One copy of this section should be filled out for each air contaminant source (emissions unit) covered by thisPTI/PTIO application identified in Section I, Question 5. See the application instructions for additional information.

Air Contaminant Source Installation or Modification Schedule - Check all that apply (must be completed regardless of

date of installation or modification):

New installation (for which construction has not yet begun, in accordance with OAC rule 3745-31-33). When will you beginto install the air contaminant source?after installation permit has been issued

SCC Codes - List all Source Classification Code(s) (SCC) that describe the process(es) performed by this air contaminant

source (e.g., 1-02-002-04).

See Facility Profile

Emissions Information - The following table requests information needed to determine the applicable requirements and the

compliance status of this air contaminant source with those requirements. Suggestions for how to estimate emissions may

be found in the instructions to the Emissions Activity Category (EAC) forms required with this application. If you need further

assistance, contact your District Office/Local Air Agency representative.

If total potential emissions of HAPs or any Toxic Air Contaminant (as identified in OAC rule 3745-114-01) are greater

than 1 ton/yr, fill in the table for that (those) pollutant(s). For all other pollutants, if “Emissions before controls (max),

lb/hr” multiplied by 24 hours/day is greater than 10 lbs/day, fill in the table for that pollutant.

Actual emissions are calculated including add-on control equipment. If you have no add-on control equipment,

“Emissions before controls” will be the same as “Actual emissions”.

Actual emissions and Requested Allowable should be based on operating 8760 hr/yr unless you are requesting federally

enforceable operating restrictions to limit emissions. If so, calculate emissions based on requested operating restrictions

and describe in your calculations.

If you use units other than lbs/hr or ton/yr, specify the units used (e.g., gr/dscf, lb/ton charged, lb/MMBtu, tons/12-

months).

Requested Allowable (ton/yr) is often equivalent to Potential to Emit (PTE) as defined in OAC rule 3745-31-01 and OAC

rule 3745-77-01.

One copy of this section should be filled out for each air contaminant source (emissions unit) covered by thisPTI/PTIO application identified in Section I, Question 5. See the application instructions for additional information.

Air Contaminant Source Installation or Modification Schedule - Check all that apply (must be completed regardless of

date of installation or modification):

New installation (for which construction has not yet begun, in accordance with OAC rule 3745-31-33). When will you beginto install the air contaminant source?after installation permit has been issued

SCC Codes - List all Source Classification Code(s) (SCC) that describe the process(es) performed by this air contaminant

source (e.g., 1-02-002-04).

See Facility Profile

Emissions Information - The following table requests information needed to determine the applicable requirements and the

compliance status of this air contaminant source with those requirements. Suggestions for how to estimate emissions may

be found in the instructions to the Emissions Activity Category (EAC) forms required with this application. If you need further

assistance, contact your District Office/Local Air Agency representative.

If total potential emissions of HAPs or any Toxic Air Contaminant (as identified in OAC rule 3745-114-01) are greater

than 1 ton/yr, fill in the table for that (those) pollutant(s). For all other pollutants, if “Emissions before controls (max),

lb/hr” multiplied by 24 hours/day is greater than 10 lbs/day, fill in the table for that pollutant.

Actual emissions are calculated including add-on control equipment. If you have no add-on control equipment,

“Emissions before controls” will be the same as “Actual emissions”.

Actual emissions and Requested Allowable should be based on operating 8760 hr/yr unless you are requesting federally

enforceable operating restrictions to limit emissions. If so, calculate emissions based on requested operating restrictions

and describe in your calculations.

If you use units other than lbs/hr or ton/yr, specify the units used (e.g., gr/dscf, lb/ton charged, lb/MMBtu, tons/12-

months).

Requested Allowable (ton/yr) is often equivalent to Potential to Emit (PTE) as defined in OAC rule 3745-31-01 and OAC

rule 3745-77-01.

lb/hr” multiplied by 24 hours/day is greater than 10 lbs/day, fill in the table for that pollutant.

Actual emissions are calculated including add-on control equipment. If you have no add-on control equipment,

“Emissions before controls” will be the same as “Actual emissions”.

Actual emissions and Requested Allowable should be based on operating 8760 hr/yr unless you are requesting federally

enforceable operating restrictions to limit emissions. If so, calculate emissions based on requested operating restrictions

and describe in your calculations.

If you use units other than lbs/hr or ton/yr, specify the units used (e.g., gr/dscf, lb/ton charged, lb/MMBtu, tons/12-

Report – Petmin USA Incorporated

1.0 INTRODUCTION & SCHEDULE

Petmin USA Incorporated (Petmin) proposes a project (hereinafter referred to as the Project) to

construct and operate a new facility to produce merchant pig iron (MPI). The projected annual

production is 470,000 tons MPI per year. The maximum theoretical plant capacity (assuming 8,760

hours per year production) is 526, 738 tons MPI per year. The new facility will be located within

the Kinder Morgan (KM) Pinney Dock facility at 1149 East Fifth Street, Ashtabula, Ohio.

The proposed Project constitutes a new major stationary sourcea under the federal Prevention of

Significant Deterioration (PSD) preconstruction permitting regulations. Ohio EPA administers the

PSD preconstruction review process as part of its Permit to Install (PTI) program, approved in its

State Implementation Plan. This engineering report, and supporting forms and attachments,

comprise a complete PTI application package for the Project, including the requisite elements

described in Ohio Administrative Code (OAC) §3745-31-11 through 20.

Once constructed, the Petmin plant will also be required to apply for and obtain a Part 70 (also

known as “Title V”) federal operating permit.

As demonstrated in this report, with respect to the federal list of Hazardous Air Pollutants (HAPs),

the plant is classified an area source (i.e., below the thresholds for a major HAP source).

The principal raw material to produce MPI consists of iron pellets. KM will provide logistic

services to handle incoming iron ore pellets and outgoing pig iron ingots on a contract basis. The

ship unloading, storage and transfer of iron pellets to the new Petmin manufacturing facility will

be performed by KM.

The scope, or boundary of the Project described in this engineering report begins at the receipt of

iron pellets from KM at the new Petmin plant and ends with the production of cast nodular pig

iron shapes as its final product. Slag produced as a byproduct transfers ownership and

responsibility immediately upon being tapped from the electric arc furnace. Its handling is also

outside the boundary of the project. A waste gas (principally composed of carbon dioxide) is also

proposed to be transferred to a third-party for purification and sale as an alternative to Petmin

discharging the waste gas. Under this operational scenario, the environmental treatment of this gas

stream becomes the responsibility of the third part gas purification plant owner. These project

boundary limits are presented in detail in this engineering report.

a Please note that the use of italics in this report denotes a term with a specific regulatory definition.

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 2 -

This report and supporting information comprising a complete PTI application was submitted to

Ohio EPA Division of Air Pollution Control in September 2018. A DRAFT PTI was issued

November 14, 2018. A public notice was published November 16, 2018. A public meeting was

held December 20, 2018. Ohio EPA extended the requisite comment period by 19 days to January

4, 2019. Following its response to comments, Ohio EPA issued a FINAL PTI on February 6, 2019.

The permit application and technical report were based on the best available information. This

revision to the report updates a number of parameters associated with the project to reflect final

design values. The overall scope of the project, the applicable federal and state requirements, and

the air pollution control technology have not changed.

1.1 Updates from Previous Reports

The first technical report was submitted September 10, 2018, and was subsequently revised in

October 2018 as follows:

• Revision to the Ladle Heater, from a single heater rated at 19.15 MMBtu/hour to three

heaters, each rated at 9.0 MMBtu/hour. Total facility emissions are not changing from this

revision, only the emissions from the ladle heater emissions unit. This is because the ladle

heaters vent to the EAF baghouse and its emissions are calculated based on the maximum

production rate, which isn’t changing.

• Other various minor corrections to descriptions of emissions units throughout the report.

• Updated modeling, Section 5, due to requests from Ohio EPA.

This revision incorporates a number of final design aspects to the project. These updates are listed

as follows:

• CO emission rate for the EAF updated, triggering BACT review for CO emissions.

• Minor change to the Electric Arc Furnace production rate, with a corresponding change to

the NOx emission rate from the EAF.

• Particulate matter emission rate updated for fabric filters to use an absolute (i.e., outlet

concentration-based) efficiency, with corresponding expansion of BACT section.

• Addition of two additional emergency engines to the Project, for fire protection.

• Consideration of the third-party CO2 Processing Plant as a medium-term overall Project

objective in as a novel technology for a DRI manufacturing facility, but not required in the

PTI for operation of the plant. Sulfur control requires a thermal oxidizer and an absorption

tower (scrubber) to convert the sulfur by oxidation to SO2, then absorb the gas into an

aqueous phase for reaction with a neutralizing agent and subsequent offsite shipment.

• Addition of a wet scrubber to treat stripped wastewater – in order to absorb ammonia in

gas phase to an aqueous phase for offsite shipment and disposal.

• Refinement of PM calculations for material handling, based on final design details of

transfer operations.

• Clarification that the third-party slag processing company takes ownership of the slag at

the furnace.

• Corresponding updates to the ambient impact analysis (air dispersion modeling report).

• Minor corrections to technical descriptions based on review by the process engineering

design team.

1.2 Project Schedule

Key milestones in the current project schedule are as follows. Future permit issuance dates are

targets. Petmin is committed to providing complete and detailed responses to comments or

questions during the review period to facilitate timely and efficient review by Ohio EPA staff.

2.0 PROJECT AND PROCESS DESCRIPTION

The Project consists of the construction and operation of a facility to produce Merchant Pig Iron

(MPI) from iron pellets. More specifically, Petmin will produce nodular pig iron, the highest purity

grade of merchant pig iron.

Merchant pig iron contains at least 92% iron, for a degree of purity of around 96%. It is typically

separated into three main categories:

1. basic pig iron: used mainly in electric arc steelmaking

2. foundry pig iron (also known as haematite pig iron): used in mainly in the manufacture

of grey iron castings in cupola furnaces

3. high purity pig iron (also known as nodular pig iron): used in the manufacture of ductile

[also known as nodular or spheroidal graphite – SG] iron castings.1

Table 3 presents the proportion of chemical components contained in merchant pig iron.

Merchant Pig Iron Chemical Components

MPI Types Iron Carbon Silicon Manganese Sulfur Phosphorus

Basic Pig Iron 92% 3.5 – 4.5% <1.5% 0.5 – 1.0% <0.05% <0.12%

Haematite Pig Iron 92% 3.5 – 4.5% 1.5 – 3.5% 0.5 – 1.0% <0.05% <0.12%

Ductile/Nodular Pig Iron 92% 3.5 – 4.5% 0.05 – 2.0% <0.05% <0.05% <0.04%

Annual potential production is 526,739tons. The fundamental manufacturing process is an

established and proven technology – the direct reduction of iron pellets to form Direct Reduced

Iron (DRI). However, purification via smelting in an electric arc furnace (EAF) to produce MPI is

a novel technology. As described in this section, Petmin will be employing a technologically

advanced process for heat recovery and in-process recycling and reuse of process gases.

Natural gas is used as a reducer source (i.e., to produce reducing gases), as well as for fuel for

combustion to provide heat energy to the preheating furnace. A description of the process is found

in the following section.

2.1 Project Location

The Project will be located within the footprint of the Kinder Morgan Pinney Dock (KM) facility,

in the county and city of Ashtabula, as indicated by the arrow in the map in Figure 1. The site is

approximately 575 feet above sea level.

2.2.1 Pellet Unloading and Handling

Ships bearing iron ore pellets will arrive at the KM dock. Most will self-unload to a storage pile

on the dock. KM will transfer the pellets into a hopper discharging to a Petmin feed conveyor belt.

The inclined conveyor belt crosses above the railroad tracks and feeds the Petmin screening

building. As there is no pellet storage in the production facility, the pellet material handling will

be essentially a continuous process beginning with the first hopper.

As shown in the following Material Handling Flowchart, KM initially handles the iron pellets for

Petmin. With respect to operations and air quality permitting, KM has responsibility for the pellets

up to the transfer point into the pellet hopper. The Project emissions begin at this transfer point.

Figure 3: Material Handling Flowchart

The pellets are screened in the screening building to remove fines, which are transferred offsite.

Pellets are sprayed with a slurry made from cement and recycled process water to coat the pellets

before going into the reactor following a curing period.

2.2.2 DRI Reactor and Process Gas Loop

In the reactor, the direct reduction of iron oxides into metallic iron is accomplished by reacting the

iron pellets in a countercurrent fashion with reducing gases. Oxygen attached chemically to the

iron reacts with hydrogen (H2) and carbon monoxide (CO), therein producing highly metallized

pellets, called direct reduced iron (DRI).

Reducing gases are generated directly by in-situ reforming of natural gas inside the reactor. Once

treated, the reaction gases are reintroduced into the reactor with a fresh natural gas make-up. For

this process, called “Zero Reformer” (ZR), the reactor could be imagined as two reactors in series:

1. A top cylindrical zone is where the reduction reactions determine the product metallization;

and

2. An intermediate zone, which is the more active zone, for in-situ reforming, pellet reduction

and the carburization reactions that control the final carbon content of the product.

The bottom cone is used only for discharging the product into the hoppers before being transferred

to the EAF.

The iron ore pellets are fed to the top of the reactor, via hoppers, and flow by gravity through the

hot reducing gases, which are ascending the reactor bed in a counter-current fashion. Natural gas

is continuously added to process gas. This mixture of natural gas and process gas is heated to a

temperature of 950°C (1,740°F) in a process gas heater and then mixed with oxygen in order to

increase its temperature by partial and controlled combustion before being finally fed to the

reactor. The distribution of gas across the bed of the reactor is uniform and ensures intimate

contact between gas and solid pellets.

The metallic iron of the pellet acts as the catalyst of the methane cracking reaction, and the gas is

converted into reforming gas (H2 and CO). The operating temperature in the reactor is maintained

above 1,080°C (1,980°F).

The primary reforming reactions are:

CH4 + CO2 → 2CO + 2H2

CH4 + H2O → CO + 3H2

These reactions occur in the lower part of the reaction zone, which means that hydrogen and carbon

monoxide are produced in the intermediate zone of the reactor and move toward the upper part of

the reactor, where they encounter the iron ore pellets, primarily consisting of Fe2O3. The reaction

Page 65: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

with hydrogen and carbon monoxide produces water and carbon dioxide, respectively. This

reduction reaction simultaneously converts the Fe2O3 to metallic iron (Fe). The primary reduction

reactions are:

Fe2O3 + 3H2 → 2Fe + 3H2O

Fe2O3 + 3CO → 2Fe + 3CO2

Reduction and carburization reactions take place simultaneously in the cylindrical portion of the

reactor, depending on the temperature (heat energy), which is the main driving force for the

kinetics of each particular reaction. Based on the operating temperatures of the ZR process, the

hydrogen-based dry reduction reactions are favored, allowing the production of DRI with a high

level of metallization.

The catalyst, in this case the iron (Fe) in the pellet, is continuously regenerated by the counterflow

of gases with the fall of the pellets by gravity into the reactor. The carburization reaction which is

favored in the ZR process has the advantage of producing DRI with more than 90% of the carbon

fixed as Fe3C.

A rotary valve, located at the bottom of the vessel, regulates the continuous gravity flow of the

charge downward through the reactor. DRI is distributed into two pressurized buffer bins (EAF

bins) by automated mechanisms. From these EAF bins, the hot DRI, now containing 94%

metalized iron, is transferred into the EAF feed hopper.

At the reactor exit, the process gas temperature is around 400°C to 450°C (750°F – 840°F). In

passing through a heat recovery unit, the thermal energy of this gas is recovered in the form of

steam. The process gas is then passed through a quench followed by a venturi, which effects both

the extraction of solids as well as cooling of the gas. Scrubbed gas is then passed through a process

gas separator where the quench water is separated from the process gas. The quench water is sent

to the plant’s wastewater treatment unit for solids recovery. Once cleaned, it is reused as

quenching water. The scrubbed gas exiting the separator is further cooled and condensed in a

quenching cooling tower. The gas is then compressed and aftercooled. One portion of the

quenched gas is fed to the process gas heater as a combustible, while another portion is sent to the

CO2 removal unit. Once the CO2 is removed, the compressed process gas is mixed with make-up

natural gas and is reheated by the process gas heater, thus closing the reduction gas cycle.

The condensed water is sent to the cooling tower and once cooled is sent back to the reduction unit

as a quenching and cooling agent.

During normal process conditions, a pilot flame will always be present in order to ensure rapid

lighting of the flare in the presence of gas. This flare also allows the process gas to be burned in

a safe manner during shutdown and start-up of the reactor and also during certain transitory

conditions (for example when the quality of the process gas is such that it cannot be used as a

combustible for the process gas heater). It is anticipated that during the first year of operation, the

startups and shutdowns could be more frequent while the plant is fully commissioned and

debugged. At that point, it is expected that typically two or three startups /shutdowns may be

encountered each year.

2.2.3 CO2 Removal

CO2 must be removed from gas exiting the reduction reactor in order to avoid being accumulated

in the process gas that is used as a reducing element. The system is composed of two columns

along with peripheral equipment. The first column is used to absorb the acid gases (CO2 and H2S)

and the second releases acid gases and regenerates amine. CO2 and H2S are extracted by

absorption. Gas circulates in the absorber and enters into contact while going countercurrent to

the methyl diethanolamine solution (MDEA at a concentration of around 50%) containing no

absorbed acid gases (regenerated amine).

The gas at the top of the absorber is washed with water in order to prevent amine build-up in the

treated gas. Demineralized water is continuously added in the absorber to make up for the water

lost in the purified process gas and in the acid gases of the regenerator.

From the absorber, the amine solution containing absorbed acid gases (enriched amine) is heated

via a heat exchanger and sent to the desorption column where it is further heated with a reboiler,

allowing carbon dioxide (CO2) and hydrogen sulfide (H2S) to be released. From the regenerator

exit, water vapor is extracted by a condenser.

Finally, the regenerated amine solution is returned to the absorber after being cooled to achieve

the required temperature while the process gas is returned to the reduction unit.

Part of the regenerated amine flow is filtered with activated carbon and centrifuged in order to

avoid the build-up of solids to extend the useful life. The centrifugation will generate a sludge,

containing mainly iron dust and a mix of water and MDEA. The sludge will be disposed of off-

site.

The gas containing CO2 and H2S may then be treated in either one of the following two options.

Petmin is requesting a permit that allows for operation under Scenario 2, which also covers

operation under Scenario 1 in order to account for uncertainties associated with the operation,

reliability, and long-term viability of a gas purification plant.

Scenario 1 – Gas Purified for Sale

In this scenario, the gas stream is sold to an independent third-party who processes the gas in a

CO2 Processing Plant onsite. This separate facility purchases the CO2 gas stream from the Petmin

facility as its feedstock and purifies the CO2. This process is described in more detail in Section

3.

The CO2 Processing Plant receives the CO2 that contains H2S. The sulfur is removed in the third-

party’s gas purification process, and the purified CO2 is sold on the commercial market.

Petmin recognizes that the CO2 processing plant will require planned maintenance activities.

Typically, these maintenance events will be planned and executed at the same time the DRI plant

is undergoing planned maintenance activities. Petmin also recognizes that the CO2 plant could

require some type of unscheduled maintenance or repair activity, or equipment breakdown of some

type, that would necessitate the temporary shutdown and “maintenance or safety bypass” of the

CO2 recovery plant.

Bypass of the CO2 Processing Plant requires a means to remove the hydrogen sulfide (H2S) from

the gas. For this reason, Petmin will have a thermal oxidizer in the bypass vent to oxidize the H2S

to sulfur dioxide, followed by a liquid, packed tower scrubber to remove the sulfur dioxide prior

to discharge of the resultant gas stream to the atmosphere via the PGH stack.

Scenario 2 – Gas Treated to Remove Sulfur and Discharged to Atmosphere

As a new venture with a degree of uncertainty, Petmin recognizes a number of possible situations

whereby CO2 purification/sale may not be practicable, or the CO2 Processing Plant may experience

a long-term shutdown. Under Scenario 2, the sulfur is removed from the CO2 offgas with the

sulfur-lean gas thereafter being discharged to atmosphere.

Just as in the “bypass mode” described in Scenario 1, the CO2 (with its contaminant H2S) is treated

in two steps:

• Oxidation of the H2S to SO2 with a thermal oxidizer, then

• Removal of the SO2 with an absorption column (i.e., packed tower scrubber), transferring

the sulfur, in dissolved solid salt form, to wastewater for pretreatment and discharge to the

City of Ashtabula. The SO2 scrubber will be designed to achieve a 98 percent removal

efficiency.

Addressing the Two Possible Operating Scenarios in the Permit to Install

Petmin is requesting authorization to operate under Scenario 2. This authorization also provides

Petmin the flexibility to operate under Scenario 1.

2.2.4 H2S Injection

Dimethyl disulfide (DMDS) is first heated by being mixed with a portion of the process gas and

then injected into a small, molybdenum and cobalt-based catalyst bed, where it is converted to H2S

and then added to make-up gas (maximum concentration of 25 ppmvd) upstream of the process gas

heater. The H2S allows the internal surfaces of the process gas heater to be protected from

corrosion. As noted above, the H2S exits the process gas loop and is oxidized to sulfur dioxide,

which is removed with a scrubber.

2.2.5 Reduction Process Start-up

The reactor takes approximately twenty-four hours to start up. Initially during start-up, the reactor

is empty, cold and pressurized with N2 gas. The feed rate of the package boiler is increased. The

reduction circuit is pressurized with nitrogen. The process gas heater and the reduction-sector

compressor are started, and iron pellets are fed to the reactor, which is full for around eleven hours

of start-up. The amine solution is preheated using steam from the package boiler. During this

time, only nitrogen is fed into the reduction circuit. Starting from the tenth hour of start-up, before

adding natural gas as a reducing agent, the preheated gases are sent to the gas quencher. The

temperature at the exit of the process gas heater gradually increases and reaches 850°C (1,560°F)

after eleven hours of start-up.

During the twelfth hour of start-up, injection of natural gas as a reducing agent commences, oxygen

is added downstream of the process gas heater, process gas is gradually formed, and, starting from

the thirteenth hour, reducing gas is fed to the reactor and the reduction of pellets commences. Over

a period of around four to six hours, part of the process gas exiting the reactor is sent to the flare

as it does not have the required quality to be used as fuel in the process gas heater. The other part

is sent to the CO2 removal unit.

Over the next eight hours, the flowrates of natural gas (as a source of reducing gas) and process

gas reach their desired values and the adjustment of operation parameters allows for the operation

to reach steady-state. At the end of the twenty-fourth hour, the DRI has the desired quality and

the normal production rate is attained.

Over several hours, the DRI metallization rate is less than the desired level. The off-spec DRI

produced during start-up is sent to a conveyor where its temperature is reduced through direct

contact with water in a quenching cooling conveyor. The off-spec DRI (also called “Remet”) is

Page 69: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

recovered, temporarily stockpiled, and returned to the iron ore pellet conveyor feed hopper where

it is fed at a low input rate.

2.2.6 Reduction Process Shutdown

During the first five hours of reduction process shutdown, the production rate is gradually slowed,

until the injection of natural gas as a reducing agent is halted, the addition of combustion oxygen

is stopped (downstream of the process gas heater) and the CO2 removal unit is shutdown. Starting

from the sixth hour, the feeding of reducing gas to the reactor is replaced by nitrogen and reducing

gas is diverted to the gas washer. Process gas from the reactor is then sent to the flare. The reactor

is emptied. The amine solution is cooled.

The temperature of the process gas heater is gradually decreased until the fourteenth hour when it

is completely shut down. Over the next six hours, the reactor is completely emptied, and the

reducing gas compressor is shut down. The reduction circuit, including the reactor is finally

purged with nitrogen for the last two hours of shutdown.

2.2.7 Smelting in the Electric Arc Furnace and Pig Iron Casting

The hot DRI pellets are liquefied in an electric arc furnace (EAF) at around 1,500°C (2,730°F),

producing two distinct phases: metal and slag. The heat of melting of the pellets is achieved using

an electric current generated by three graphite electrodes.

A buffer silo (receiving hopper) is needed to couple the continuous reduction process to the semi‐

continuous melting process. The average feed rate to the EAF is 60.13 tons per hour. The EAF

operating cycle is known as a tap-to-tap cycle. The function of the feed rate and the electrical

supply as a function of time elapsed is described below.

• The total melting cycle lasts approximately 132 minutes.

• The hot DRI (approximately 675°C, 1,250° F) is fed to the EAF at a rate of 1.2 tons per

minute for around 60 minutes.

• The feed rate is then increased to around 1.4 tons per minute for approximately forty to

forty-five minutes and eventually diminishes to close to 1.2 tons per minute over the last 5

to 7 minutes.

• While the DRI is being loaded, the electric supply varies between 32 and 37 MW.

• The heat produced by the electric arc furnace melts the DRI at a temperature above 1,500°C

(2,730° F).

• During the next twenty minutes, the electric current ceases, and the loading of the EAF is

interrupted. The slag is deposited, the batch is sampled, and the metal is tapped.

Page 70: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Petmin USA Incorporated

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 15 -

• Once the tapping is finished, around 12 minutes are necessary to prepare the equipment for

the next cycle. During this period the level of the graphite electrodes is adjusted.

• Total yield per cycle is approximately 132.3 tons of liquid metal and 20.7 tons of slag.

In order to minimize heat losses during the transport of hot DRI between the reactor and the EAF,

the reactor is approximately thirty meters higher and placed near the EAF in order to feed by

gravity.

During the loading of DRI in the EAF, a mixture of lime and dololime is added (around 0.88 ton

per batch). Bauxite may also be added to adjust the characteristics of the slag. This flux agent

facilitates the separation of impurities contained in the pellets and is essential to controlling the

quality of the pig iron.

Metal, now containing more than 96% iron, is poured into ladles and transported to the pig caster,

which is cooled by direct contact with water. Water evaporates upon contact with hot metal and

make-up water is added to the circuit. Pig iron product drops from the pig caster to an outdoor

bunker before being moved to a storage pile awaiting shipment.

The slag byproduct is transferred to an independent third party at the point of its formation, i.e.,

pouring into the slag pots owned and transported by the third-party. The Slag Processing

Contractor (SPC) slag pot transport vehicle moves the pot containing molten slag to a slag

processing area operated by the SPC where the slag is decanted, cooled, and solidified. Once

cooled and solidified, the slag is broken into blocks which are then transported by the SPC to the

SPC’s processing facility.

2.2.8 EAF Fume Capture System

The primary fumes generated during DRI melting will be extracted through the hood around the

electrodes on the furnace roof, by a water-cooled duct. The connection between the furnace hood

and water-cooled ducts is obtained with a movable sliding skirt foreseen to allow the change of

the gap for the air inlet; the sliding skirt is located on the first fixed duct. After this connection,

before the fixed cooling duct line, the arrangement of a settling chamber – or drop out box (DOB)

– will allow for the combustion of CO and separation of the heaviest particles of dust from the off‐

gasses.

The main parameter to be controlled for optimum primary fume suction, according to the EAF

working conditions, is the pressure inside the furnace. For maintenance reasons, the pressure probe

is located inside the furnace duct elbow. The target is to have slightly positive pressure in the EAF

Page 71: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Report – Petmin USA Incorporated

- 16 -

to avoid the direct suction and consequent infiltration of fresh air, which would unnecessarily

oxidize the EAF bath.

The secondary fume generated during the various furnace operating phases is controlled with a

canopy hood located on the main building roof. The canopy hood is designed according to the

EAF dimensions and levels to maintain the required ventilation inside the main melt shop building.

Figure 4: Primary and Secondary EAF Hoods

Figure 4 shows only the primary and secondary EAF hoods. There are additional hoods dedicated

to ladles, casting, bins, loading, etc. which ensure that the entire EAF building is evacuated to the

baghouse.

2.2.9 Auxiliary Boiler

A package boiler, with a heat input capacity of 15.2 million BTU per hour, will supply the steam

necessary to the CO2 removal unit as well as the energy necessary during the start-ups and

shutdowns of the facility. The vast majority of the time, the auxiliary boiler will function at a

minimal load.

2.2.10 Storage Silos

Lime, dololime and bauxite will be stored in silos (capacity of 120 m3 each) outside of the smelting

and casting building. The vent on each silo will be connected to the EAF baghouse duct system.

3.0 FEDERAL & STATE RULE APPLICABILITY

This section presents a summary of program applicability, and emissions limitations and standards

that apply to the proposed Project.

The Project is located in Ashtabula, OH, which is designated as attainment or unclassified for all

air pollutants for which a National Ambient Air Quality Standard (NAAQS) has been established.

Therefore, the federal regulations for Prevention of Significant Deterioration (PSD) apply for all

relevant pollutants.

3.1 Defining the Scope of the Project for Regulatory Analysis and Permitting

A first step in evaluating regulatory applicability involves defining the scope, or battery limits of

the Petmin Project. Under its EPA-approved NSR rules, Ohio EPA retains the ultimate discretion

to make source determinations.

3.1.1 Kinder Morgan Terminal a Separate Stationary Source

As described in Section 2, KM will be contracted to provide iron pellets to the Petmin hopper. At

its Pinney Dock Terminal, KM routinely provides unloading, storage and material handling

services for various bulk commodities and general cargoes. The terminal encompasses 310 acres,

with 200 acres of open storage, with a storage capacity of 7 million tons. Transportation modes

are by water (Lake Erie), railroad (Norfolk Southern and CSX) and major roadways (Ohio State

Route 11, Interstate 90 and the Ohio Turnpike).

At plant capacity of 526,739tons MPI production, Petmin will require 874,200 tons per year of

iron pellets. As a conservatively high estimate, a three-month supply onsite would be 218,500

tons, or 2.5 percent of KM’s storage capacity. The Terminal typically handles on the order of 6 to

8 million tons per year of bulk commodities (limestone, iron ore, mineral sands, agri-products,

rock salt, coal, coke, etc.). Therefore, the iron ore pellets handled for transfer to Petmin will

represent on the order of 10 percent of the Terminal’s typical throughput.

On April 30, 2018, U.S. EPA issued clarifying guidance (referenced hereinafter as the “Common

Control Memorandum”) for purposes of determining when, for New Source Review purposes, a

facility is not under common control, and thus is its own unique “stationary source.2 Following

the principles of this guidance, KM and Petmin are clearly distinct, separate stationary sources for

purposes of NSR applicability. Key facts include:

1. No Common Control – According to the Common Control Memorandum, “the most relevant

considerations should be whether entities have the power to direct the actions of other entities to

the extent that they affect the applicability of and compliance with permitting requirements.”

• KM and Petmin share no common ownership. Petmin will have no control over, or “power to

direct” KM’s pollutant-emitting or permit compliance activities.

• KM has distinctly separate ownership, management, employees, and environmental staff.

• KM has its own, longstanding Ohio Permit to Install and Operate for its terminal operations,

with existing capacity for handling Petmin’s iron pellets, as described in Section 2 of this

report.

• KM is not dependent on Petmin for compliance with any portion of the requirements associated

with the material handling of iron pellets for delivery to Petmin.

• KM and Petmin will have a mutually beneficial contract for the supply of iron pellets to the

Petmin hopper. However, neither has the power or ability to direct the relevant activities of the

other.

2. Line of Demarcation – As described in Section 2, a clear line of demarcation sets the battery limits

for KM activities relative to Petmin. Petmin takes responsibility for the iron pellets at the feed

hopper supplying the Petmin plant.

3. Dissimilar operations, as shown by Standard Industrial Codes (SIC):

• Petmin SIC: 3312

• KM SIC: 4213 – Marine Cargo & Handling

In conclusion, Petmin does not control KM simply because KM will store Petmin’s iron pellets

and transfer those pellets to the hopper that feeds Petmin’s conveyor system. Second, there is no

indication that Petmin has any power or authority over other activities at KM. KM simply handles

a feedstock under a mutually beneficial arms-length arrangement between the two wholly-separate

business entities. Under the Common Control Memorandum, it appears clear that U.S. EPA would

not consider Petmin and KM part of the same stationary source.

3.1.2 Carbon Dioxide Plant a Separate Stationary Source

As described in Section 2, Petmin is seeking a mutually beneficial arrangement with a specialty

gases producer to sell its untreated CO2 from the DRI reactor gas recovery loop as feedstock to a

CO2 Processing Plant. If proven to be viable, CO2 capture and treatment provides the

environmental benefit of reducing greenhouse gas emissions from manufacturing MPI.

Plant Description

As described in Section 2, Petmin is requesting a Permit to Install that provides for, but does not

require, the operation of a CO2 Processing Plant. The CO2 Processing Plant, if constructed, will

require an approximately ¾ acre footprint, with a total of up to as much as 5 acres for material

handling (truck staging and/or rail siding). The exact site of the plant has not yet been determined

Page 75: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

but will be sited as close to the Petmin equipment as possible in order to obviate a booster

compressor.

The CO2 feedstock stream will contain the following low-level contaminants that require removal

to produce 4.0 grade CO2: hydrogen sulfide, hydrogen, carbon monoxide and methane.

The precise design details of the gas purification process are under development by potential third-

parties. In one current proposal, the independent company will compress the feed stream raw

process gas, rich in CO2 from approximately 3 to 6 pounds per square inches gauge pressure (psig)

to approximately 320 psig. Hydrogen sulfide will be removed via a scavenger process. Water will

be removed from the stream in several stages of the process. Methane, hydrogen and carbon

monoxide will be removed via regenerative chemical adsorption processes. Nitrogen will be

removed in a distillation and boiling process.

Purified CO2 will be liquefied and subcooled to approximately (minus) -10 F° and then stored at

between 250 and 275 psig. After removal of the impurities, the plant will provide approximately

15 tons per hour (~30,700 pounds per hour) of 99.99+ percent purity 4.0 grade CO2.

The H2S will be removed and the sulfur-bearing adsorption media handled as follows (or

equivalent process):

The sulfur is adsorbed in a two-bed, lead / lag setup with a material such as Axens AxTrap 4513, which

is a patent-pending, high-capacity non-hazardous granular media specifically designed for use in the

removal of H2S. The media adsorbs contaminant level carbonyl sulfide, mercaptans and organic

sulfides, if present, from CO2 for total sulfur control. It is comprised of a porous mixed zinc-metal

oxide formed on a stable inert base along with an inorganic adsorption phase specific for heavier sulfur

compounds.

The beds are designed for an estimated 180 days on line (per bed) and then switched while the spent

bed is being replenished. The spent material is ether sent back to Axens or landfilled (non-hazardous).

Methane and CO are removed as separate streams of the Carbon Dioxide Plant (CDP) purification

steps. Depending on final costs and technical details, there are two possibilities:

• Methane and CO will be sold back to Petmin and reintroduced with the feed gas to the DRI; or

• Methane and CO will be flared, with a minimum removal efficiency of 98%,

The CDP will obtain its own PTIO from Ohio EPA, if one is required. (Note: It may be the case

that no PTIO is required). Similarly, the CDP will also have permitting and compliance

Page 76: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

responsibility for wastewater discharges, solid waste, and other applicable environmental

programs.

The CDP will take ownership of the untreated gas stream. The CDP will also assume responsibility

for its plant’s equipment malfunctions and, if it were to occur, the associated release of

uncontrolled feedstock gas. The CDP may also be responsible for acceptance of feedstock gas

during Petmin startup and shutdown.

As noted above, CDP details have not been finalized. Petmin is seeking a PTI that provides for

operation of its plant with or without a CDP.

While not critical to the following analysis of “common control,” it is also noteworthy that the

determination of independent control for a CDP does not impact program applicability for Petmin.

The controlled emissions of CO and methane are minor source level emission rates.

• Controlled CO emissions are less than 10 tons per year.

• Controlled methane emissions are less than 10 tons per year.

• Even if Petmin did have ownership responsibility for these emissions (which, according to the

Common Control Memorandum, they would not) the Petmin Project would remain below the

significance threshold for CO. Petmin already triggers BACT review for Greenhouse Gas

Emissions. The additional methane emissions would be trivially small.

Analysis with Respect to the Common Control Memorandum

This business relationship closely matches the situation described in the Common Control

Memorandum. There, a collocated independent business entity is purchasing landfill gas and

purifying it to pipeline quality natural gas. In the case here, an independent business will be

purchasing untreated CO2 as feedstock and purifying it to high quality CO2.

In both cases, the ownership and management of the gas purchaser/purification plant is clear. The

company that produces the gas as a byproduct of its principal operation has no ownership,

management, or other nexus that would suggest “control” of the gas purification plant. Key facts

include:

1. No Common Control – According to the Common Control Memorandum, “the most relevant

considerations should be whether entities have the power to direct the actions of other entities to

the extent that they affect the applicability of and compliance with permitting requirements.”

• The Carbon Dioxide Plant (CDP) and Petmin would share no common ownership. Petmin

would have no control over, or “power to direct” the CDP’s pollutant-emitting or permit

compliance activities.

• The CDP would have distinctly separate ownership, management, employees, and

environmental staff.

• The CDP would acquire its own PTIO, if one is required. The CDP is not dependent on Petmin

for compliance with any portion of the requirements associated with the purification and sale

of the CO2.

• The CDP and Petmin would have a mutually beneficial contract for the purchase of feedstock,

then the CDP’s purification and resale, of high grade CO2.

2. Line of Demarcation – A clear line of demarcation sets the battery limits for the CDP activities

relative to Petmin. The CDP takes responsibility for the CO2 gas stream at a single designated point

in a closed vent system from Petmin that feeds the CDP.

3. Dissimilar operations, as shown by Standard Industrial Codes (SIC):

• Petmin SIC: 3312

• CDP SIC: 2813 – Industrial Gases

In conclusion, Petmin would not control the CDP. The CDP will purchase the untreated CO2 gas

stream and take responsibility at the transfer point. Second, there is no indication that Petmin

would have any power or authority over other activities at the CDP. Petmin simply would supply

a feedstock under a mutually beneficial arms-length arrangement between the two wholly-separate

business entities. Under the Common Control Memorandum, it appears clear that U.S. EPA would

not consider Petmin and the CDP part of the same stationary source.

3.1.3 Slag Processor a Separate Stationary Source

In addition to the untreated CO2 described in the previous section, the other principal byproduct

from the Petmin manufacturing process is metallurgical slag.

Petmin is negotiating with an independently owned third-party Slag Processing Company (SPC)

to take ownership and responsibility (using the SPC’s equipment) of the slag at its point of

generation, i.e., as it is poured from the EAF into the SPC-owned slag pots. The third-party vendor

will also manage the slag stockpile. No processing of slag is proposed to be performed onsite,

although the third-party vendor may need to break up the slag into a manageable size prior to

loading tri-axle dump trucks and moving the slag off-site.

As described in Section 2 of this report, slag is poured to the slag pot from the EAF; then, metal,

now containing more than 96% iron, is poured from the EAF into ladles and transported to the pig

caster, which is cooled by direct contact with water and by contact with the air. Water evaporates

upon contact with hot metal and make-up water is added to the circuit.

Each SPC-owned slag pot can hold several EAF loads. The SPC transports the pot containing

cooled and solidified slag to the storage area. Close to ground level, the transport vehicle angles

Page 78: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

- 23 -

the pot and the block of slag falls to the ground. From there, the slag is transported via the

contractor to an outside facility.

The SPC and Petmin are clearly distinct, separate stationary sources for purposes of NSR

applicability. Key facts include:

1. No Common Control – According to the memorandum, “the most relevant considerations

should be whether entities have the power to direct the actions of other entities to the extent that

they affect the applicability of and compliance with permitting requirements.”

• The SPC and Petmin share no common ownership. Petmin will have no control over, or “power

to direct” the SPC’s pollutant-emitting or permit compliance activities.

• The SPC has distinctly separate ownership, management, employees, and environmental staff.

• The SPC will have its own, separate, minor source PTIO with Ohio EPA, if one is required.

• The SPC is not dependent on Petmin for compliance with any portion of the requirements

associated with the slag processing from receipt to its shipment offsite.

• The SPC and Petmin will have a mutually beneficial contract for the handling and removal of

slag. However, neither has the power or ability to direct the relevant activities of the other.

2. Line of Demarcation – A clear line of demarcation sets the battery limits for SPC activities relative

to Petmin. The SPC takes ownership and control of the slag upon its discharge from the furnace

into the SPC-owned slag pot.

3. Dissimilar operations, as shown by Standard Industrial Codes (SIC):

• Petmin SIC: 3312

• SPC SIC: 3295 – Minerals and Earths, Ground or Otherwise Treated

In conclusion, Petmin does not control the SPC simply because it transfers ownership of its slag

byproduct. Second, there is no indication that Petmin has any power or authority over other

activities at the SPC. Petmin simply supplies a byproduct which then becomes a feedstock for the

SPC under a mutually beneficial arms-length arrangement between the two wholly-separate

business entities. Under the Common Control Memorandum, it appears clear that U.S. EPA would

not consider Petmin and the SPC part of the same stationary source.

3.2 Federal Rule Applicability

This section summarizes the applicability of federal rules and standards to the Project and its

emissions.

3.2.1 Prevention of Significant Deterioration (PSD)

As confirmed with Ohio EPA Division of Air Pollution Control, the manufacture of MPI categorizes

Petmin into one of the source categories in OAC 3745-31(NNN)(2)(a). Therefore, the major source

Page 79: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Environmental Protection Agency, et al. No. 12-1146, June 23, 2014, GHGs subject to PSD review only

if the proposed project is subject to PSD review for at least one non-GHG regulated NSR pollutant.

Project emissions of oxides of nitrogen (NOx), carbon monoxide (CO) and greenhouse gases (GHG)

exceed the major source threshold. Therefore, the Project triggers PSD review. The Project then

triggers PSD review for all PSD pollutants that exceed the significant emission rate. As shown in the

above table, the Project triggers PSD review for:

• Oxides of nitrogen (NOx)

• Carbon monoxide (CO)

• Particulate matter less than 10 microns (PM10)

• Particulate matter less than 2.5 microns (PM2.5)

• Greenhouse gases (GHG)

OAC 3745-31-11 through -20 are the regulations for PSD in Ohio. Any new major stationary source

or major modification of an existing major source located in an air quality attainment area3 must

undergo a PSD review. Consistent with Ohio PSD regulations and EPA guidance, the PSD review

consists of the following elements:

• An analysis of best available control technology (BACT) for emissions of those pollutants

for which the project results in a significant net emissions increase from the source.

• An air quality impact analysis to demonstrate that the proposed project will not exceed the

NAAQS for CO and NOx, and thus will not lead to significant deterioration in air quality;

• A Class I impact analysis to demonstrate the proposed project will not impact Class I

protected wilderness areas.

• An additional impacts analysis (e.g., impacts on soil, vegetation, visibility) to demonstrate

that additional impacts resulting from the proposed project are not expected.

Sections 4, 5, and 6 of this report present the results of these analyses.

3.2.2 National Emission Standards for Hazardous Air Pollutants (NESHAP)

MACT Subpart ZZZZ - Stationary Reciprocating Internal Combustion Engines

The Project will include two emergency generators, two emergency fire protection pumps, and one

black start generator. The emergency generators and fire protection pumps, excluding emergency

3.2.4 Preconstruction Permit Requirements

OAC 3745-31-02(A) provides that a Permit to Install (PTI) is required from Ohio EPA prior to

initiating construction or modification of a source of air contaminants unless specifically exempted

in OAC 3745-31-03. The PTI issued by Ohio EPA fulfills the preconstruction permitting

requirements under federal PSD rules. A construction permit is required for the Petmin project.

This report and its attachments are provided as a complete application package, compiled to

include all the various elements required for issuance of a PSD permit.

OAC 3745-31-05 requires all new sources to minimize emissions using the best available

project does not involve a generator. The CAIR are not applicable. Note that both cited state rules

were rescinded on January 29, 2018.

3.2.6 Title V Federal Operating Permit Program

Petmin is subject to rule 40 CFR 70 and OAC 3745-77, as a major facility under these rules. The

application process for a Title V operating permit for a new stationary source in Ohio begins after

the issuance of the final PTI and after the plant has begun operations. Petmin will be required to

submit an application for a Title V operating permit within one year of startup. The PTI authorizes

the operation of the plant until a final Title V permit is issued by Ohio EPA. For a new source, the

Title V permit typically mirrors the PTI in its facility and emissions-unit specific terms and

conditions.

3.2.7 Compliance Assurance Monitoring

The EAF baghouse is subject to the requirements of 40 CFR 64. A CAM plan is required by 40

CFR 64.2(a) because the EAF is subject to a PM standard and uses a control device to reduce

uncontrolled emissions that would exceed the major source threshold. A CAM Plan will be

submitted with the Title V permit application.

3.2.8 Other Applicable Emission Limitations and Standards

No other federal emission limitations or standards have been found to apply to the proposed

project.

3.3 State of Ohio Regulations & Standards

This section summarizes the applicability of Ohio-specific regulations and standards.

3.3.1 General Requirements

The following rules apply to all sources or air contaminants in Ohio for which a PTI is required.

Annual Emissions Fee

Ohio EPA will assess a separate fee based on the total annual emissions from the facility.

Emissions are self-reported in accordance with Ohio Administrative Code (OAC) Chapter 3745-

78. This fee assessed is based on a fee schedule in ORC section 3745.11 and funds Ohio EPA's

permit compliance oversight activities.

Scheduled Maintenance

Scheduled maintenance of air pollution control equipment must be performed in accordance with

OAC rule 3745-15-06(A). If scheduled maintenance requires shutting down or bypassing any air

pollution control equipment, the operator must also shut down the emissions unit(s) served by the

air pollution control equipment during maintenance, unless the conditions of OAC rule 3745-15-

06(A)(3) are met. Any emissions that exceed permitted amount(s) under the permit (unless

specifically exempted by rule) must be reported as deviations.

Malfunction Reporting

A reportable malfunction of any emissions unit(s) or any associated air pollution control system,

must reported to the Ohio EPA District Office in accordance with OAC rule 3745-15-06(B).

Malfunctions that must be reported are those that result in emissions that exceed permitted

emission levels. The permittee has the responsibility to evaluate control equipment breakdowns

and operational upsets to determine if a reportable malfunction has occurred.

Ohio EPA Authorization to Inspect, Require Tests, Request Information

Under Ohio law, the Director or his authorized representative may inspect the facility, conduct

tests, examine records or reports to determine compliance with air pollution laws and regulations

and the terms and conditions of the permit. The permittee is required to provide, within a

reasonable time, specific types of information Ohio EPA requests either verbally or in writing.

Prohibition of Air Pollution Nuisances

The final PTI and OAC rule 3745-15-07 prohibit operation of the air contaminant source(s)

regulated under this permit in a manner that causes a nuisance. Ohio EPA can require additional

controls or modification of the requirements of this permit through enforcement orders or judicial

enforcement action if, upon investigation, Ohio EPA determines existing operations are causing a

nuisance.

Emissions Unit-Specific Exemptions

Certain emissions units are permanently exempt from obtaining a PTI, as listed in OAC rule 3745-

31-02. Certain emissions units are exempt from air pollution control requirements and from PTI

requirements based on de minimis emission rates of regulated air pollutants and HAPs, pursuant

to OAC rule 3745-15-05. However, the potential to emit from these otherwise exempt units must

be included in the facility-wide potential to emit analysis for purpose of major source applicability

criteria.

Opacity

OAC 3745-17-07(A) limits opacity from stacks to 20% as a six-minute average and OAC 3745-

17-07(B) limits opacity from non-stack (fugitive) sources to 20% as a three-minute average. For

new sources, a lower limit is often established as part of the BAT determination.

3.3.2 Criteria of the Director and Best Available Technology

OAC rule 3745-31-05 stipulates that a PTI shall be approved and issued based on an application

satisfactorily demonstrating that the installation and operation will employ Best Available

Technology (with specific exceptions noted).

(Note: State BAT should not be confused with the generally more stringent federal requirement

for a Project to meet BACT for the pollutants that exceed a significant emission rate).

"Best available technology" or "BAT" means any combination of work practices, raw

material specifications, throughput limitations, source design characteristics, an evaluation

of the annualized cost per ton of air pollutant removed, and air pollution control devices

that have been previously demonstrated to the director of environmental protection to

operate satisfactorily in this state or other states with similar air quality on substantially

similar air pollution sources.

In general, BAT determinations are made by Ohio EPA in accordance with an Ohio EPA

Interoffice Memo issued February 7, 2014.4

3.3.3 Particulate Matter

OAC 3745-17-08 requires control measures be implemented for sources of fugitive dust in areas

of the state defined by Appendix A. The city of Ashtabula, including the Petmin site, are included

in Appendix A.

OAC 3745-17-10(B)(1) limits particulate emissions from gas-fired boilers and heaters to not more

than 0.020 pound per million BTU actual heat input.

OAC 3745-17-11(A)(2) limits particulate emissions from processes by applying two different

calculations, one based on maximum throughput of processed materials, and the other based on

the uncontrolled emission rate. This rule is rarely relevant to new emissions units, as a lower limit

or control requirement is established in its place under the BACT or BAT requirement.

3.3.4 Sulfur Dioxide Emissions

OAC 3745-18-06(A) exempts natural gas combustion from the sulfur dioxide limits. OAC 3745-

18-06(E) calculates an emission limit from process sources in Ashtabula County based on their

maximum process weight rate, in tons per hour, with the equation: 30 P0.67. As with the calculated

particulate matter limits, the allowable emission rate calculation for sulfur dioxide often yields an

unreasonably high value that is replaced with a lower BAT limit.

3.3.5 Control of Oxides of Nitrogen (NOx)

OAC 3745-110 requires that reasonably available control technology (RACT) be applied to any,

“very large boiler, large boiler, mid-size boiler, small boiler, stationary combustion turbine,

stationary internal combustion engine, or reheat furnace”, unless exempted by OAC 3745-110(K),

which includes:

(1) Any industrial boiler having a maximum heat input of less than or equal to twenty mmBtu/hr.

(2) Any emergency standby boiler, stationary internal combustion engine, or stationary combustion

turbine which operates less than five hundred hours during any consecutive twelve-month period.

However, the owner or operator of the emergency standby engine, boiler, or turbine shall maintain

for a period of not less than three years, in a bound log book, or other format acceptable to the

director, a list of the dates and number of hours the emergency standby engine operated.

Petmin has no equipment or processes to which this rule applies. Neither the process gas heater

nor the EAF are included in the regulated units described in the applicability statements. The

miscellaneous natural gas-fired equipment is exempted (and below the defined input capacity for

‘small boiler’) and the emergency generators are also exempted.

NOx-emitting sources will, however, be limited as a result of the BACT analysis as part of the PSD

review.

3.4 State of Ohio Regulations and Standards – By Emissions Unit

This section provides a summary of the Ohio emissions limitations and standards applicable to

each specific emissions unit. The table lists the state rules applicable to each emissions unit. The

subsequent discussion will concentrate on the best available technology (BAT) approach being

3.4.1 Process Gas Heater

The reduction gas, consisting of H2 and CO, is heated by the process gas heater combusting natural

gas supplemented by a lesser amount of CO and H2 recovered in the reconditioning loop. The process

gas heater emits only the products of combustion, utilizing a total of 218.9 million BTU per hour

input capacity low-NOx burners.

Opacity Standard

The process gas heater is defined as ‘fuel-burning equipment’ and exhausts through a stack.

Therefore, the standard of 20% opacity as a 6-minute average and associated exceptions in OAC rule

3745-17-07(A) apply.

PM Standard

The limit of 0.020 pounds PM per million BTU of gaseous fuels combusted in OAC rule 3745-17-

10(B) is also applicable. The unit burns a combination of natural gas and process gas. The unit can

be expected to be inherently compliant with this limit based on the use of these clean gaseous fuels.

- 34 -

SO2 Standard

The county-specific sulfur dioxide rule (OAC 3745-18-10) does not list Petmin and the general

emission limitations in OAC 3745-18-06 are not applicable to this combustion unit.

BAT

The emissions unit is subject to the PM and opacity limits described above. BAT for NOx is equivalent

to the selected technology discussed in the BACT review.

Petmin requests that the BAT for NOx be expressed as a source design characteristic. The proposed

process gas heater burner is designed to emit no more than 0.064 pounds NOx per million BTU

heat input.

3.4.2 Quenching & Wastewater Treatment Waste Gas

The quenching and wastewater treatment system normally operates at a de minimis level except

during startup and shutdown, when process gas is vented to the flare in order to combust the hydrogen

and carbon monoxide. There is only one planned shutdown and startup per year.

PM Standards

The process gas contains only combustion-related PM. Therefore, OAC rule 3745-17-11 does not

apply.

Opacity Standards

The visible emission standards do not apply to an “air contaminant source which is not subject to any

mass emission limitation in paragraphs (B)(3) and (B)(4) of rule 3745-17-08 of the Administrative

Code, or rule 3745-17-09, 3745-17-10 or 3745-17-11 of the Administrative Code.”

SO2 Standard

The county-specific sulfur dioxide rules (OAC 3745-18-10) do not list Petmin and the process

limitations in OAC 3745-18-06(E) do not apply to this source because OAC 3745-18-06(C) exempts

sources with process weight rates less than 1,000 pounds per hour.

BAT

Potential emissions of all criteria pollutants do not exceed 10 tons per year; therefore, the BAT

requirement is not triggered.

3.4.3 Ladle Preheat

The ladle preheat consists of three lances burning natural gas which are used to bring the pouring

ladles to a temperature where the refractory lining will not be damaged by thermal shock during

subsequent tapping.

PM Standards

The ladle preheat contains only combustion-related PM. Table I of OAC rule 3745-17-11 relates

process weight rate (PWR) to an allowable emission rate. Only natural gas is introduced into the

process and gaseous fuels are excluded from the definition of PWR in both OAC rule 3745-17-01 and

17-11(A)(4). Table I imposes an emission limit of 0.551 pounds PM per hour for processes with a

PWR equal to zero. Figure 2 of OAC rule 3745-17-11 does not apply because the UMRE is less than

10 pounds per hour.

Opacity Standards

The ladle preheat emissions are captured and exhausted through the EAF baghouse. Therefore, the

OAC rule 3745-17-07(A) standard of 20% opacity as a 6-minute average, and associated

exceptions, applies to the ladle preheat emissions as they exit that baghouse.

SO2 Standard

The county-specific sulfur dioxide rules (OAC 3745-18-10) do not list Petmin and the process

limitations in OAC 3745-18-06(E) do not apply to this source because OAC 3745-18-06(C) exempts

sources with process weight rates less than 1,000 pounds per hour.

BAT

Potential emissions of all criteria pollutants do not exceed 10 tons per year; therefore, the BAT

requirement is not triggered.

3.4.4 EAF, Pouring and Casting

DRI from the reactor is stored in bins before batch-loading to the EAF. A complete cycle of the

EAF is designed to process 153 tons of DRI over approximately 132 minutes, consisting of 112

minutes of smelting and 20 minutes for tapping to the ladle, yielding 132.3 tons of metal and 20.7

tons of slag. Slag is transferred to a slag pot for removal. Metal is transferred to the ladle and

subsequently poured into a water-cooled ingot casting line to produce the final product.

The EAF, ladle preheat, slagging, pouring and casting processes are located in the same building,

which is designed to fully capture the associated emissions and direct them to a baghouse. The

- 36 -

main EAF evacuation duct leads to a knock-out box where flow is reduced to settle large particles

and air is introduced to combust the CO in the hot gases and provide cooling prior to entering the

baghouse.

PM Standard

Table 1 of OAC rule 3745-17-11 requires an allowable PM limit to be calculated using the process

weight rate (P), defined for P > 30 as E = 55.0(P)0.11 – 40.0. The EAF will be able to produce 153

tons of metal and slag during a 132-minute batch. Allowable emissions for a 69.5 ton per hour

process weight rate are therefore 47.70 pounds per hour.

Figure II contains a second equation to calculate allowable emissions using the uncontrolled mass

rate of emissions (UMRE). There are no available estimates of UMRE for the EAF: AP-42 only

shows a controlled emission factor and the supplier of Petmin’s equipment provides only a design

outlet concentration for the fabric filter. However, an examination of Figure II indicates that the

proposed design outlet concentration would necessarily comply with Figure II or else be associated

with a UMRE of less than 10 pounds per hour and not be subject to Figure II.

Therefore, both methods of calculating an allowable emission rate from OAC rule 3745-17-11

yield results that are less restrictive than that resulting from BAT and BACT.

Opacity Standard

The EAF and associated processes are subject to OAC rule 3745-17-11 and exhaust through a

stack. Therefore, the OAC rule 3745-17-07(A) standard of 20% opacity as a 6-minute average,

and associated exceptions, applies.

BAT

The fumes generated during the smelting in the EAF are extracted from the roof of the furnace via

a flexible suction pipe cooled with water leading to a sedimentation chamber (“drop-out box”).

The overall ventilation system is designed to maintain a negative pressure inside the building, and

vent it to the EAF baghouse. This feature, along with the capture system for the EAF, provides a

capture efficiency that is presumed to be 100 percent. The configuration of the sedimentation

chamber makes it possible to separate coarse particles from the gas and the addition of air to the

hot gas (800° C) further combusts remaining CO.

The BAT limit will be equivalent to the BACT limit for CO and NOx.

Page 92: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Petmin requests that the BAT for NOx be expressed as a monthly allowable emission rate. The

proposed emissions from the EAF are based on the manufacturer’s NOx emission factor of 1.4

pounds per ton of metal times 60.13 tons of metal per hour, operating 8,760 hours per year, and

converted to tons: 1.4 x 60.13 x 8,760 ÷ 2,000 = 368.72 tons per year. As a monthly value, 368.72

÷ 12 = 30.7 tons NOx per month.

Petmin requests that the BAT for CO be expressed as a source design characteristic.

Petmin requests that the BAT for PM be expressed as a source design characteristic. The proposed

EAF baghouse is designed to emit no more than 0.0025 grain PM per standard cubic foot of exhaust

gas.

3.4.5 Material Handling

Material handling operations controlled by Petmin include the transfer, conveying, and screening of

iron ore pellets that have been loaded into the conveying system hopper by a third party.

Materials produced in the EAF are not expected to contain fines. Partially reduced iron ore pellets

(Remet) diverted from the reduction reactor during startup or shutdown have already had fines

removed during processing. Slag is a solid that is not processed on site. (Note: It may be necessary to

break large pieces to facilitate truck loading, but this operation is performed by an independent third

party). Ingots (“pigs”) are solid cast metal. Handling pigs for shipment is not expected to result in

particulate emissions as there would be negligible fines or dust.

Fluxes are pneumatically conveyed to storage silos and fed to the process through closed feeders

inside a building vented to the EAF baghouse. These material handling operations are considered to

be de minimis.

PM Standards

The transfer, conveying, and screening of iron ore pellets has the potential to generate fugitive dust

and is subject to OAC rule 3745-17-08. The rule prescribes control measures that must be taken to

minimize or eliminate such emissions, i.e., application of water or other dust suppressants to open

sources or the capture of fugitive emissions with venting to fabric filters.

Opacity Standards

The visible emission standards in OAC rule 3745-17-07(B)(1) are applicable because the site is located

within an Appendix A area. Visible emissions of fugitive dust are limited to 20% opacity as a 3-minute

average.

BAT

Potential emissions of PM10 exceed 10 tons per year and therefore the BAT requirement is

applicable. The BAT limit is equivalent to the BACT requirement.

The conveyors and transfer points will be designed to minimize or eliminate visible emissions of

fugitive dust. Where appropriate, e.g., screens, emissions will be captured and vented to a

baghouse with a maximum designed outlet concentration of 0.0025 gr/dscf.

3.4.6 Roadways and Parking Areas

Petmin leases land within an existing facility that has its own permitted roadways. Contractually,

Petmin is responsible for roadways only on its own leased property. The calculations provided

with this application provide detailed information concerning these roadway segments and

associated traffic.

PM Standards

The operation of vehicles on plant roads has the potential to generate fugitive dust and is subject to

OAC rule 3745-17-08. The rule prescribes control measures that must be taken to minimize or

eliminate such emissions, i.e., application of water or other dust suppressants to open sources.

Opacity Standards

The visible emission standards in OAC rule 3745-17-07(B)(1) are applicable because the site is

located within an Appendix A area. Visible emissions of fugitive dust are limited to 20% opacity

as a 3-minute average.

BAT

Potential emissions all criteria pollutants do not exceed 10 tons per year and therefore the BAT

requirement is not triggered.

3.4.7 Emergency Engines and Black Start Generators

The emergency generators and fire protection pumps are sized to maintain vital functions in the

event of a power outage. They do not have the capacity to provide the power needed to sustain

production operations. The black start generator will provide power only during startup from a

cold condition. These startups are expected to occur, ideally only one time, but, accounting for

unplanned shutdowns, a few times per year.

All five diesel engines will be current models meeting the Tier 4 requirements and subject to

MACT subpart ZZZZ and NSPS subpart IIII, as described in 3.2 and below. The federal rules for

limit operation to less than 100 hours per year for maintenance and readiness testing. There is no

limit on the number of hours allowed during emergencies.

PM Standards

The emergency generators are “stationary large internal combustion engines” and will comply with

OAC rule 3745-17-11(B)(5)(b). The fire protection pumps and the black start generator are

“stationary small internal combustion engines” and will comply with OAC rule 3745-17-

11(B)(5)(a).

Opacity Standards

The emergency engines and black start generator exhaust through stacks. Therefore, the standard

of 20% opacity as a 6-minute average, and associated exceptions, applies to each stack.

SO2 Standard

The sulfur dioxide limit for the emergency generators is specified in OAC 3745-18-06(G) because

it will be greater than ten MM Btu per hour total rated capacity; the black start generator will be

less than ten MM Btu per hour total rated capacity and exempted by OAC 3745-18-06(B).

BAT

Potential emissions all criteria pollutants do not exceed 10 tons per year and therefore the BAT

requirement is not triggered.

4.0 BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS This section presents the BACT analysis for the Project.

4.1 Introduction

The source is located in Ashtabula County, which is currently designated as attainment or

unclassifiable for PM/PM10/PM2.5, NOx, CO, SO2, and VOC. Therefore, these pollutants were

reviewed pursuant to the PSD Program.

As summarized in Section 3.2, the Project is subject to PSD review for the following pollutants:

• Oxides of nitrogen (NOx)

• Carbon monoxide (CO)

• Particulate matter less than 10 microns (PM10)

• Particulate matter less than 2.5 microns (PM2.5)

• Greenhouse Gases (GHG)

BACT is an emission limitation based on the maximum degree of reduction of each pollutant

subject to the PSD requirements. In accordance with the “Top-Down” Best Available Control

Technology Guidance Document outline in the 1990 draft U.S. EPA New Source Review Workshop

Manual (the Manual), this BACT analysis takes into account the energy, environmental, and

economic impacts on the source. The BACT analysis addresses the above four pollutants.

Reductions may be determined through the application of available control technologies, process

design, and/or operational limitations. Such reductions are necessary to demonstrate that the

emissions remaining after application of BACT will not cause or contribute to significant

deterioration of air quality, thereby protecting public health and the environment.

The “Top-Down” approach in the Manual is summarized as the following 5-step process:

Table 1: Identify all control technologies.

Table 2: Eliminate technically infeasible options.

Table 3: Rank remaining control technologies by control effectiveness.

Table 4: Evaluate the most effective controls and document results.

Table 5: Select BACT.

BACT must also, at a minimum, meet any applicable New Source Performance Standard (NSPS)

under 40 CFR, Part 60 and Maximum Achievable Control Technology (MACT) standard under

40 CFR Part 61 – 63. For this Project, as described in Section 3, NSPS standards apply only to

the emergency engines and black start generators; no MACT standards are applicable.

BACT review for that pollutant. The units are listed in the decreasing order of maximum emission

rates; the BACT analysis will also follow this sequence, as “returns on investment” in controls (in

The operation of the EAF was described in Section 2. An EAF can be described as a furnace

heating charged materials by the way of an electric arc.

An electric arc furnace used for steelmaking consists of a refractory-lined vessel, usually water-

cooled in larger sizes, covered with a retractable roof, and through which one or more graphite

electrodes enter the furnace. The furnace is primarily split into three sections:

• The shell, which consists of the sidewalls and lower steel bowl;

• The hearth, which consists of the refractory that lines the lower bowl; and

• The roof, which may be refractory-lined or water-cooled, and can be shaped as a section

of a sphere. The roof also supports the refractory delta in its center, through which one or

more graphite electrodes enter.

A typical alternating current furnace has three electrodes. The arc is formed between the charged

material and the electrode. The charge is heated both by current passing through the charge and

by the radiant energy evolved by the arc. The electric furnaces can be categorized as direct arc or

indirect arc. Both types of units are suited for the melting of high melting point alloys such as

steels.

The picture below shows an electric arc furnace.

Figure 5: Electric Arc Furnace

In the EAF, NOx will be produced at the electric arc. There is a substantial difference between

conventional EAF operations for steelmaking and the Petmin EAF designed for MPI production.

The principal difference between an EAF used in steelmaking and the Petmin EAF is the arc

exposure. In conventional steelmaking the arc is protected by a foamy slag layer that minimizes

the contact with the surrounding atmosphere. For MPI production, the arc is totally exposed to the

furnace atmosphere, which increases nitrogen oxidation (formation of thermal NOx). This EAF

operation is similar to an EAF designed for stainless steel-making, where the molten bath operates

with no foamy slag.

The Petmin EAF is a unique, first-of-its-kind design for MPI production. NOx formation is

complex, and difficult to predict for a new technology. Emission factors for NOx were developed

based on a proprietary model by its design engineers.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

US EPA has compiled the following general set of potential options for reducing NOx5. Potential

application to the Petmin EAF is described for each option, quoted directly from the EPA manual.

Method 1. Reducing Temperature – Reducing combustion temperature means avoiding the

stoichiometric ratio (the exact ratio of chemicals that enter into reaction). Essentially, this

technique dilutes calories with an excess of fuel, air, flue gas, or steam. Combustion controls use

different forms of this technique and are different for fuels with high and low nitrogen content.

This option generally applies to combustion processes. It is infeasible for the Petmin EAF. The

temperature cannot be reduced.

Method 2. Reducing Residence Time – Reducing residence time at high combustion

temperatures can be done by ignition or injection timing with internal combustion engines. It can

also be done in boilers by restricting the flame to a short region in which the combustion air

becomes flue gas. This is immediately followed by injection of fuel, steam, more combustion air,

or recirculating flue gas. This short residence time at peak temperature keeps the vast majority of

nitrogen from becoming ionized. This bears no relationship to total residence time of a flue gas in

a boiler. This option generally applies to combustion processes. It is infeasible for the Petmin

EAF. The residence time cannot be reduced.

Method 3. Chemical Reduction of NOx – This technique provides a chemically reducing (i.e.,

reversal of oxidization) substance to remove oxygen from nitrogen oxides. Examples include

Selective Catalytic Reduction (SCR) which uses ammonia, Selective Non-Catalytic Reduction

(SNCR) which use ammonia or urea, and Fuel Reburning (FR). Non-thermal plasma, an emerging

technology, when used with a reducing agent, chemically reduces NOx. All of these technologies

attempt to chemically reduce the valence level of nitrogen to zero after the valence has become

higher. Some low-NOx burners also are based partially on this principle. According to the process

engineering design firm applying this EAF technology to MPI production, it is not possible due to

conditions of the furnace.

More specifically, SCR is not feasible since it requires clean and hot exhaust gases where the NOx

waste gas is introduced. In the EAF for MPI production, the waste gas stream is hot and it carries

dust, then it is cleaned only when it is cold. Operating a SCR system under its hot condition would

simply clog the scrubbing system.

When evaluating technical feasibility, it should be recognized that, with enough engineers, time,

and money, a system could, in theory, be designed and built as long as it does not violate the laws

of thermodynamics. In this sense, it could be theoretically possible to construct an exhaust gas

reheat system and SCR control downstream of the EAF baghouse. With a starting point of 171°F

and 356,000 acfm, the waste gas would first need to be heated to the 480°F to 800°F range where

SCR reactions occur.6 At 500°F, the waste gas stream would increase to 542,000 acfm, plus

additional combustion gases required for reheating (plus additional NOx formation). A technically

feasible control strategy is an “available technology” that has been demonstrated to function

efficiently on an emissions unit that is identical or similar to the unit under review7. Applying

SCR technology in this manner would be impractical, has not been demonstrated on a similar unit,

and is ruled out as technically infeasible.

Selective Non-Catalytic Reduction (SNCR) uses a reducing agent, typically urea or ammonia,

injected directly into the exhaust of combustion processes such as coal-fired boilers at a point

where the temperature is between 1,800° and 2,100°F. Conditions in the EAF exhaust do not

match SNCR applicability. This technology is technically infeasible.

Other chemical reduction technologies are also infeasible:

• Non-Selective Catalytic Reduction (NSCR), the NOx reduction technology used on fuel

rich combustion systems such as automobiles (with downstream oxidation catalyst) is only

applicable to combustion systems such as reciprocating engines. There are no known

applications of NSCR to a source similar to the EAF.

• Non-thermal plasma is an emerging technology under development on a laboratory scale

and has not been proven for large-scale application.

Method 4. Oxidation of NOx – This technique intentionally raises the valence of the nitrogen ion

to allow water to absorb it (i.e., it is based on the greater solubility of NOx at higher valence). This

is accomplished either by using a catalyst, injecting hydrogen peroxide, creating ozone within the

air flow, or injecting ozone into the air flow. Non-thermal plasma, when used without a reducing

agent, can be used to oxidize NOx. A scrubber must be added to the process to absorb N2O5

emissions to the atmosphere. Any resultant nitric acid can be either neutralized by the scrubber

liquid and then sold (usually as a calcium or ammonia salt), or collected as nitric acid to sell to

customers. These technologies are generally not suitable for use on the EAF and are technically

infeasible. One emerging technology, discussed below, is not considered to be an “available

technology,” as it has not yet been proven in similar sources.

EMx™ (SCONOX) is an add-on control device that catalytically oxidizes NO to NO2 and then

adsorbs the NO2 onto a potassium carbonate coated surface. The potassium carbonate is

Page 101: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

regenerated using steam injected hydrogen, to react with the nitrates and nitrites to form water and

elemental nitrogen. This technology has been demonstrated on relatively small combined-cycle

gas turbines. Use on pre-cleaned EAF gas with iron fines would foul or plug the catalytic oxidation

process, and this technology would be infeasible. Moreover, this technology has not been applied

to an EAF or similar source.

LoTOx™ is a technology where ozone is injected into the waste gas stream to oxidize insoluble

NOx to soluble N2O2, which predominantly reacts in moisture to form nitric acid. The nitric acid,

along with N2O2 and nitrous acid, are removed using a caustic scrubber, i.e., absorption tower.

Despite being ruled out as economically infeasible at a cost of $84,000 per ton of NOx removed, a

demonstration project was planned for a DRI-fed indurating furnace at the former Essar Steel

facility in Minnesota.8 After bankruptcy proceedings, the plant is still considered to be under

construction by Mesabi Metallics LLC, with a construction completion target date unknown at this

time. Further, it is unknown at this time whether the demonstration project will be pursued.

Therefore, this technology remains unproven for an EAF, and is eliminated as technically

infeasible.

Method 5. Removal of nitrogen from combustion – This is accomplished by removing nitrogen

as a reactant either by: (1) using oxygen instead of air in the combustion process; or (2) using ultra-

low nitrogen content fuel to form less fuel NOx. This option is not feasible for an EAF; there is no

fuel or combustion process.

Method 6. Sorption, both adsorption and absorption – Treatment of flue gas by injection of

sorbents (such as ammonia, powdered limestone, aluminum oxide, or carbon) can remove NOx

and other pollutants (principally sulfur). There have been successful efforts to make sorption

products a marketable commodity. This kind of treatment has been applied in the combustion

chamber, flue, and baghouse. The use of carbon as an adsorbent has not led to a marketable

product. The sorption method is often referred to as using a dry sorbent, but slurries also have

been used. The use of dry sorbents and slurries has been proven for sulfur dioxide treatment but

is not proven for NOx control. This technology is infeasible for the EAF.

Method 7. Combinations of these methods – Many of these methods can be combined to achieve

a lower NOx concentration than can be achieved alone by any one method. With none of the above

approaches considered feasible for the EAF, a combination method is also not feasible.

As additional research to identify available technologies, EAFs were searched via the EPA

RACT/BACT/LAER Clearinghouse database. No new control technologies were discovered from

this search.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

No feasible add-on control technology was found for this emissions unit. This EAF is a one-of-a-

kind design for smelting DRI, in which the arc is directly exposed to the furnace atmosphere, with

no foamy slag layer. The emission factor for the EAF was developed based on a similar design

used in making stainless steel.

Step 4: Evaluate the Most Effective Controls and Document Results

A “no add-on controls” case is the most effective control for the Petmin EAF.

BACT Emission Limitations at Other Facilities

The EPA database system, RACT/BACT/LAER clearinghouse (RBLC), provides emission limit

data for industrial processes throughout the United States. The US EPA Workshop Manual

stipulates that a BACT analysis should also include a technology review of similar sources. The

units found, based on a search of permits issued in the last 10 years, were all carbon steel processes;

no stainless steel EAF was listed in the database.

Based on the emission factor provided by the EAF design team, at capacity the Petmin EAF will

emit 368.72 tons NOx annually to manufacture 526,739tons MPI, which translates to 1.4 pounds

of NOx emitted per ton of finished MPI. This summary table confirms what was previously known,

that the use of a direct arc, with no foamy slag layer between the arc and metal, results in higher

temperatures and NOx formation than EAFs in conventional steel-making.

The unique Petmin EAF is not directly comparable to any of these units listed in the table. Further,

the Petmin EAF provides other environmental benefits, in producing high-purity, nodular grade

merchant pig iron in an energy efficient manner that can compete with producers on a global

market. These benefits are not reflected in the NOx emissions values. Furthermore, the emission

factor is based on an emissions model developed by the furnace manufacturer. NOx formation is

highly complex. As typical for unique, emerging-technology processes, the emission factor can

be re-evaluated upon source measurement (stack testing) when the unit achieves its design

production rate.

Not listed in the RBLC database, a recent PSD permit for a stainless steel EAF in Alabama was

modified to account for high thermal NOx formation that had been mischaracterized in the original

permit application. The original permit, issued for 0.35 pounds NOx per ton metal production, was

modified to 1.0 pounds NOx per ton metal, based on stack test results.9

Another stainless steel facility, North American Stainless, in KY, has two EAFs that have

undergone PSD review. One has an emission rate of 1.32 pounds NOx per ton plus 0.578 pounds

per ton from the Argon Oxygen Decarburization step, for a total emission rate from smelting

operations of 1.898 pounds NOx per ton of metal produced. The other EAF is 1.0 plus 0.58 for a

total emission rate of 1.58 pounds NOx per ton of metal produced. The excerpt from this permit

Step 5: Select BACT

Based on the information presented above, the NOx BACT option selected is no add-on controls,

and a NOx emission factor of 1.4 pounds NOx per ton of MPI production. Therefore, BACT for

this unique piece of equipment consists of:

• NOx emissions of 1.4 pounds NOx per ton of MPI produced;

• Direct Evacuation Control (DEC) for capture of air contaminants, as described in Section

2 of this report.

4.3.2 Process Gas Heater

The Process Gas Heater (PGH) is a natural gas-fired heater that has been custom engineered for

Petmin to supply the process gas at the optimum temperature, flow and pressure to the DRI reactor.

Some cleaned process gas from the reconditioning loop, containing hydrogen, methane, and carbon

monoxide, is also burned. The PGH has been specified with low-NOx burners.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

Low NOx Burners

“Low NOx burners reduce NOx by accomplishing the combustion process in stages. Staging

partially delays the combustion process, resulting in a cooler flame which suppresses thermal NOx

formation. NOx emission reductions of 40 to 85 percent (relative to uncontrolled emission levels)

have been observed with low NOx burners.”10 It is important to note that the actual reduction

achievable is also highly dependent on the specific application.

The use of Low NOx burners is a minimum standard in the industry and is considered the

“baseline” for the Project. Low NOx burner technology applied to the custom-designed PGH

achieves a NOx emission rate of 40 ppmv, which translates to an emission factor of 0.064 pounds

NOx per million BTU of heat input.

SCR

The SCR process chemically reduces the NOx molecule into molecular nitrogen and water vapor.

A nitrogen-based reagent such as ammonia is injected into the ductwork, downstream of the

combustion unit. The waste gas mixes with the reagent and enters a reactor module containing

catalyst. The hot flue gas and reagent diffuse through the catalyst. The reagent reacts selectively

with the NOx within a specific temperature range and in the presence of the catalyst and oxygen.11

Preliminary design data indicate that combining SCR would reduce the NOx emission rate from

Ranking the feasible controls by effectiveness:

• Low NOx with SCR: 75% reduction

• Low NOx: Baseline

Step 4: Evaluate the Most Effective Controls and Document Results

Cost Evaluation - SCR

A cost estimate for SCR was developed using U.S. EPA’s Office of Air Quality Planning &

Standards “Air Pollution Control Cost Estimation Spreadsheet for Selective Catalytic Reduction,

May 2016.” The worksheet is provided as Appendix 2.

Source-specific data input to the model include the fuel type, NOx emission rate, expected

reduction, air flow, exhaust temperature, and site elevation. A urea-based reagent system for the

supply of ammonia was selected for safety reasons at the heavy industrial-type site.

The default interest rate of 7 percent was used, consistent with OAQPS regulatory analyses12.

In this context, n is the control system economic life, which, as stated above, typically varies from

10 to 20 years. The interest rate (i) used in this Manual is a pretax marginal rate of return on

private investment of 7% (annual). This value, which could also be thought of as a “real private

rate of return”, is used in most of the OAQPS cost analyses and is in keeping with current OAQPS

guidelines and the Office of Management and budget recommendation for use in regulatory

analyses.

The Chemical Engineering Plant Cost Index (CEPCI) was updated from the 2012 value of 584.6

to June 2018 of 601.17. The current CEPCI is not available in the public domain. As an unbiased

estimate, the value was estimated from the January 2018 CEPCI, then scaling the value based on

the June-to-January increase in the Consumer Price Index. (Note: this was an extremely minor

adjustment and had an insignificant impact on final, annualized costs).

The “average” life listed in Ohio Engineering Guide 46 Table 5-3 is 10 years, and the “high”

equipment life 20 years for either a catalytic incinerator or for an absorber. As this unit would be

well maintained, but is also in a severe service environment in the metals industry, a midpoint 15-

year equipment life was selected.

Otherwise, default values were selected in the analysis.

The total Capital Cost (dollar values presented to the nearest three significant figures) for SCR for

the PGH is estimated to be $3.63 million dollars. The total annualized cost is estimated to be

$555,000. 46 tons of NOx would be removed, at a cost of $12,100 per ton of NOx removed.

A recent PSD project in Ohio13 presented a BACT Control Technology Economic Impact Analysis

for a much larger natural gas-fired (1,687 v. 218.9 MM BTU/hr) DRI preheater/reformer of a

different design. A pro forma total capital cost estimate created using the OAQPS SCR estimator

using the source-specific input data for this DRI facility is $13.7 million, v. the $24.4 million

estimate presented by the permittee in the application. Given these data, the OAQPS estimator

provided a value that is only 56% of the total capital cost presented by the applicant. This

comparison suggests that the OAQPS estimator used in this analysis may be biased low for

developing a total, installed capital cost for SCR on a DRI preheater.

Similar Source

The HYL Zero Reformer and its Process Gas Heater and associated gas reconditioning loop

comprise a proprietary, custom, unique design. An earlier version of this technology has been

installed for one other U.S. project, at Consolidated Environmental Management, a division of

Nucor, at a plant near Convent, LA. No other similar sources were identified.

In that case, SCR was selected, along with Low NOx burners, as BACT. That BACT also

mentioned the use of low-nitrogen fuel, as the reactor top gas containing CO and H2 that is used to

supplement natural gas in the PGH would be considered “low nitrogen,” thereby partially

eliminating the NOx component that comes from fuel-bound nitrogen. This is also the case for the

Petmin Project. This feature is integral to the Zero Reformer process.

A significant difference exists in controls cost effectiveness between the LA project and Petmin’s

due to economies of scale. The LA plant is designed for annual production of 6.6 million tons pig

iron, from two DRI reactors. At 3.3 million tons capacity, each PGH/reactor has seven (7) times

the capacity of the Petmin Project. The cost of add-on controls is much lower, in dollars per ton,

at this scale. By increasing the input capacity of the PGH by 7, and re-running the SCR cost

estimator, the cost effectiveness changes from $12,100 per ton to $7,500 per ton (keeping other

key parameters – interest rate, equipment life, reagent and energy costs, etc. the same).

The EPA cost estimator indicates that total air pollution control (APC) capital cost, when

increasing pig iron production capacity by six, from 526,739tons to 3.3 million tons, increases

from $3.63 million to $12.9 million. This economy of scale tendency in APC equipment is also

described in Ohio EPA Engineering Guide 46, as the “six tenths factor.” For a first-pass estimate

of total capital cost, to scale the capital cost for a seven-fold increase in size, the multiplier would

be 7 raised to the power of 0.6, which equals 3.2. Scaling the estimated cost for the Petmin SCR

system by 3.2 yields an estimate of $11.6 million, which is in reasonable agreement with the $12.9

value from the OAQPS cost estimator.

In other words, it is expected and predictable that APC becomes significantly more cost effective

with economies of scale. This known relationship also explains how SCR technology can be cost

effective at the much larger LA plant’s Zero Reformer process, but not cost effective for the much

smaller Petmin project.

Step 5: Select BACT

Natural gas-fired Low-NOx burners (supplemented with integral low-nitrogen fuel) are cost

effective.

SCR add-on controls are technically feasible. However, $12,100 per ton of NOx removed is not

economically feasible.

BACT consists of low NOx burners, use of natural gas supplemented with an integral low-nitrogen

fuel source, and good combustion practices.

4.3.3 Ladle Preheaters

After tapping from the EAF, metal is kept molten by preheating the ladles used for pouring the

finished MPI into ingots, also known as “pigs.” Natural gas torches are used for this purpose, as

is common in the metals industry. Combustion of natural gas results in NOx emissions, with a

calculated maximum annual emission rate of 27.87 tons per year. The ladles are equipped with a

hood that is directed to the EAF baghouse.

A review of the RBLC database, a study of PSD permits obtained for other sources, and generally

available technical literature indicate that no additional controls, beyond the use of good

combustion practices and the use of natural gas, have been successfully applied to reduce NOx

emissions from ladle preheating. BACT is the use of natural gas and good combustion practices.

The operation of the EAF was described in Section 2.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Fabric Filter – Fabric filters are the standard in the iron and steel industry for most

PM10/PM2.5 control applications. Baghouses often are capable of 99.9% removal efficiencies, and

baghouse removal efficiency is relatively level across the particle size range.

The main operating limitation of a baghouse is that its operating temperature is limited by the bag

material. Most filter materials are limited to 200°F to 300°F. Some materials like glass fiber or

Nomex™ may be operated at 400°F, but are more expensive. Baghouses also do not operate well

when there is a significant amount of moisture in the stream being treated. The moisture causes

the particulates to form a very thick, wet and heavy cake that plugs the bags and cannot be

removed. The plugging significantly reduces or blocks the airflow increasing the pressure drop

across the bags or completely making the unit inoperable. High moisture levels can also weaken

some bag materials (e.g., polyester) due to hydrolysis, resulting in reduced bag life.

Baghouse control efficiency under normal loading conditions typically is in the 99+ percent range.

Reduced efficiencies will occur when the inlet particle concentration is low. Baghouse controls

Page 114: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

do not significantly affect the temperature of the stream being treated; therefore, condensable PM

control is limited to particulates present in a filterable form in the baghouse when it is being treated.

Another disadvantage of baghouses is high energy use. High efficiency filter media in baghouses

require higher pressure drops than electrostatic precipitators (ESPs). On high-flow volume

sources, the increase in pressure drop for a baghouse vs. ESP can result in significant increases in

electrical energy use. Therefore, baghouses are most effective controlling sources with filterable

particulates and less effective controlling hot exhaust streams with condensable particulates.

Baghouses are the most effective means of controlling directly emitted filterable PM2.5 because

filters are best at controlling small particles.

Method 2. Wet Scrubber – Wet scrubbers, also termed particulate scrubbers, remove particles

from waste gas by capturing the particles in liquid droplets (usually water) and separating the

droplets from the gas stream. The droplets transport the particulate out of the gas stream.

Scrubbers may capture particulates through the following mechanisms:

• Impaction of the particle directly into a target droplet.

• Interception of the particle by a target droplet as the particle comes near the droplet.

• Diffusion of the particle through the gas surrounding the target droplet until the particle is

close enough to be captured.

Scrubbers are generally classified according to the liquid contacting mechanism used. The most

common scrubber designs are spray-chamber scrubbers, cyclone spray chambers, orifice and wet

impingement scrubbers, and venturi scrubbers.

Operating conditions inside of a scrubber can be very corrosive if acid gases are present in the

waste gas, and highly abrasive PM can cause erosion problems. These conditions lead to reduced

equipment operating life and/or increased capital cost for materials of construction. Scrubber

control efficiency under normal loading conditions typically is in the 95 to 99+ percent range.

Scrubber efficiency is typically a function of pressure drop across the scrubber. Consequently,

higher collection efficiencies will consume more electrical power to operate the scrubber blower.

The temperature of an exhaust gas may be reduced in a wet scrubber due to evaporative cooling

by the scrubber water. Since wet scrubbers use water, they may also capture PM composed of

water-soluble salts. Therefore, wet scrubbers are more likely to control condensable particulates

than a baghouse or dry ESP. Reduced efficiencies will occur when the inlet particle concentration

is low. Outlet concentrations achieved will depend on the size range and nature of the particles.

Wet scrubbers are not as effective as baghouses and ESPs in controlling directly emitted filterable

PM2.5.

Method 3. Electrostatic Precipitators (ESP) – An ESP applies electric forces to separate

suspended particles from the flue gas stream. In an ESP, an intense electrostatic field is maintained

between high-voltage discharge electrodes, typically wires or rigid frames, and grounded

collecting electrodes, typically plates. A corona discharge from the discharge electrodes ionizes

the gas passing through the precipitator, and gas ions subsequently ionize the particles. The

electric field drives the negatively charged particles to the collecting electrodes. Periodically, the

collecting electrodes are rapped mechanically to dislodge collected PM, which falls into hoppers

for removal. Collector dust is removed from the precipitator for disposal, recycling or

reprocessing.

Since ESPs use electrical forces for particle collection, the electrical properties of the particles can

adversely impact ESP operation. Particles with high resistivity may not readily accept an electric

charge and will be difficult to collect. Particles with high conductivity or magnetic properties,

such as iron, will strongly adhere to the collection plates and be difficult to remove.

ESP control efficiency under normal loading conditions typically is in the 98 to 99+ percent range.

Reduced efficiencies will occur when the inlet particle concentration is low. ESPs are very

effective at removing particles larger than 1 micron. ESPs use electrostatic force to move

particulates to the collection plates. This increases the effectiveness of impaction and interception

collection mechanisms. However, electrostatic forces diminish as particle sizes decrease.

Therefore, they are not as effective as baghouses on particles 1 micron and smaller where diffusion

is the primary particulate control mechanism. Travel distances are larger in ESPs than in fabric

filters; therefore, they are not as effective as filtration in capturing sub-micron particles.

Method 4. Wet Electrostatic Precipitators (Wet ESP) – A wet ESP operates in the same manner

as a dry ESP; it applies electric forces to separate suspended particles from the flue gas stream.

However, particle removal in a wet ESP is accomplished with water sprays instead of mechanical

cleaning methods. In a wet ESP, an intense electrostatic field is maintained between high-voltage

discharge electrodes, typically wires or rigid frames, and grounded collecting electrodes, typically

plates. A corona discharge from the discharge electrodes ionizes the gas passing through the

precipitator, and gas ions subsequently ionize the particles. The electric field drives the negatively

charged particles to the collecting electrodes. As a result of using water sprays, wet ESPs generate

wastewater which must be treated to remove suspended particles and dissolved solids.

Wet ESP water sprays are effective at removing material collected on the ESP plates, but may

require more maintenance than dry ESPs in order to keep the water spray system working properly.

Wet ESP control efficiency under normal loading conditions typically is in the 98 to 99+ percent

range. Reduced efficiencies will occur when the inlet particle concentration is low. Outlet

concentrations achieved will depend on the size range and nature of the particles being filtered.

Wet ESP control efficiency for PM2.5 is similar to dry ESP controls for the reasons noted above.

Method 5. Mechanical Collectors – Mechanical collectors use a variety of mechanical forces to

collect PM:

• Inertial separators use inertia and gravity to remove the larger particles from the smaller

ones.

• Cyclones use centrifugal force to separate PM from gas streams.

Drop-out boxes are typically used as inertial separators. Larger particles are trapped in drop-out

boxes as the inertia they contain forces them to go straight as the rest of the gas stream turns to

flow into and out of the drop-out box. Particles are also removed by gravitational settling in the

drop-out box. Inertial separators can only remove the larger dust particles (>75 microns). They

are typically used upstream of other control devices in high inlet dust loading cases.

Cyclone separators are designed to remove particles by inducing a vortex as the gas stream enters

the chamber, causing the exhaust gas stream to flow in a spiral pattern. Centrifugal forces cause

the larger particles to concentrate on the outside of the vortex and consequently slide down the

outer wall and fall to the bottom of the cyclone, where they are removed. The cleaned gas flows

out of the top of the cyclone.

There are two principal types of cyclones: tangential entry and axial entry. In tangential entry

cyclones, the exhaust gas enters an opening located on the tangent at the top of the unit. In axial

flow cyclones, the exhaust gases enter at the middle of one end of a cylinder and flow through

vanes that cause the gas to spin. A peripheral stream removes collected particles while the cleaned

gas exits at the center of the opposite end of the cylinder.

Overall cyclone control efficiencies range from 50 to 99 percent with higher efficiencies being

achieved with large particles and low efficiencies for smaller particles (<PM10 and PM2.5).

Mechanical separators are often used upstream of other PM control devices to reduce the loading

on the primary control device. This improves overall control efficiency and may reduce the overall

cost of the control system when the waste gas is heavily laden with PM.

(*nominal efficiencies listed for PM10 control)

Potential control alternatives were ranked for effectiveness in controlling PM10/PM2.5 emissions

from the EAF. As noted, in general, fabric filters, if feasible, are the most effective APC method

in the metals industry.

Step 4: Evaluate the Most Effective Controls and Document Results

Fabric filters or baghouses are an industry standard for PM10/PM2.5 control in many applications.

Baghouses are capable of 99+% removal efficiencies. Baghouse removal efficiency is relatively

level across the particle size range so that excellent control of all particle sizes can be obtained.

Baghouses can be effectively applied to most dry dust sources, but are not typically effective at

very high temperatures that may burn the filter material.

Electrostatic precipitators are common dust control devices that are good at trapping dusts within

certain applications. ESPs applied to materials within the correct resistivity range can, in certain

cases, achieve very high removal efficiencies, up to 99.5%. ESPs typically have a higher initial

capital cost than baghouse controls. The presence of iron in the exhaust stream makes it likely that

the collected particulate would be difficult to remove from the plates. In addition, a wet ESP

would create a wastewater stream that would cause other environmental issues.

High-energy wet scrubbers are technically feasible and achieve good control efficiencies.

However, scrubber systems have very high pressure drops that result in high system operating

costs. They also require water treatment and sludge disposal that are not required for other PM

control options.

Mechanical collectors are effective at removing large dust particles using centrifugal forces.

However, fine dusts are typically not as effectively removed, due to the high gas stream velocity

that must be established, often keeping smaller particles entrained in the stream.

Step 5: Select BACT

An important distinction in this Project is that the particulate matter is estimated to be as much as

80 percent by weight of PM2.5. Given the expected particle size distribution of the EAF exhaust

gas, a fabric filter baghouse is the top control technology.14

Page 118: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

- 63 -

Based on the top-down BACT analysis, the best available control technology is a mechanical

collector (drop-out box) followed by a fabric filter baghouse.

Efficiency for a baghouse in the iron and steel industry is specified on an absolute basis, i.e., at a

continuous, guaranteed minimum performance in units of outlet concentration, in units of mass

per unit volume of gas. Petmin has specified a baghouse guaranteed to achieve an absolute

efficiency of 0.0025 grains per dry standard cubic feet.

Dust Capture, Baghouse Operation

The baghouse will be “pulse‐jet negative pressure” type, designed for high filtering velocity with

bag cleaning performed by means of compressed air. The filter will be constructed of separate

cells that can be isolated by dampers. Inside the filter, the flow of gases is upward, crossing the

polyester felt bags from the outside to the inside. The bags have mechanical and physical

characteristics to withstand abrasion and chemical aggression, and can operate continuously to a

maximum working temperature of 130°C. The dust particles remain attached to outside the bag

surface and are cleaned periodically by a compressed air pulse‐jet. The cleaning cycle time is

adjustable and depends on the operating phase and will be set during start up and operation.

The primary fumes generated during DRI melting will be extracted through the hood around the

electrodes on the furnace roof, by a water-cooled duct. The connection between the furnace hood

and water-cooled ducts is obtained with a movable sliding skirt to allow the change of the gap for

the air inlet; the sliding skirt is located on the first fixed duct. On the first part of the first water

cooled duct there will be a sliding cooled elbow to avoid dust deposit and to allow EAF roof

opening and maintenance works on the furnace. After this connection, before the fixed cooling

duct line, the arrangement of a settling chamber – or drop out box (DOB) – will facilitate additional

oxidation of CO and will separate the heaviest particles of dust from the off‐gasses.

Further cooling is achieved in the remaining part of the water‐cooled hot gas line. The main

parameter to be controlled for a correct primary fume suction, according to the EAF working

conditions, is the pressure inside the furnace; for maintenance reasons, the pressure probe is

located inside the furnace elbow. The target is to have slightly positive pressure in the EAF and

that is the reason why there is no water-cooled elbow on the EAF roof, so to avoid the direct

suction and consequent infiltration of fresh air, which would unnecessarily oxidize the EAF bath.

The secondary fume generated during the various furnace operating phases is controlled with a

canopy hood located on the main building roof. The canopy hood is designed according to the

EAF dimensions and operating parameters. The canopy hood is also used to maintain the required

ventilation inside the main melt shop building. In summary, BACT for PM10 and for PM2.5 for the

EAF and the pig casting operation consists of:

• Capture designed for full capture of particulate matter from the EAF

• Drop-out box pre-collector for removal of large particles, followed by

• Fabric filter (baghouse) designed to achieve an absolute efficiency of 0.0025 grain per dry

standard cubic foot percent control of filterable particulate matter

4.4.2 Material Handling and Screening

Iron ore pellets are loaded onto Petmin’s covered conveyor system by an independent third party.

Pellets are conveyed to a screening operation to remove fines before continuing to the production

building. Pellets are coated with a cement slurry prior to charging to the reactor.

Control of fugitive emissions is dependent upon the proximity of dust generation points to the

control equipment. Iron ore pellets are roughly spherical in shape, requiring conveyor belts to

have only gradual slope. Collection of dust is simplified in Petmin’s design for the screening and

production buildings, with a central dust collection system. At the tip area where pellets are loaded

into the hoppers, there is also dust suppression at the transfer points, utilizing a suppressing spray

to blanket and suppress airborne particulate matter.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Fabric Filter – Fabric filters are the standard in the iron and steel industry for most

PM10/PM2.5 control applications. Baghouses often are capable of 99.9% removal efficiencies, and

baghouse removal efficiency is relatively level across the particle size range.

Local collection hoods routed to fabric filters with enhanced filter media are the most efficient

means of removing PM10/PM2.5 from dusty sources. The advantage of local collection hoods and

bag filters is that air flows from individual collection points in the system can be adjusted to

increase or decrease collection rates, increasing the effectiveness of the system. The fabric filter

is largely insensitive to variability in dust loading that could occur during iron oxide screening,

transfers and other operations. For these reasons, local collection hoods and baghouse filters are

the industry standard for the control of particulate from iron ore pellet handling.

Method 2. Wet Scrubber – Wet scrubbers, also termed particulate scrubbers, remove particles

from waste gas by capturing the particles in liquid droplets (usually water) and separating the

droplets from the gas stream. The droplets transport the particulate out of the gas stream.

Scrubbers were described in the previous subsection.

Method 3. Electrostatic Precipitators (ESP) – An ESP applies electric forces to separate

suspended particles from the flue gas stream. In an ESP, an intense electrostatic field is maintained

between high-voltage discharge electrodes, typically wires or rigid frames, and grounded

collecting electrodes, typically plates. A corona discharge from the discharge electrodes ionizes

the gas passing through the precipitator, and gas ions subsequently ionize the particles. The

electric field drives the negatively charged particles to the collecting electrodes. Periodically, the

collecting electrodes are rapped mechanically to dislodge collected PM, which falls into hoppers

for removal. Collector dust is removed from the precipitator for disposal, recycling or

reprocessing.

ESPs were described in the previous subsection.

Method 4. Centrifugal Collectors – Centrifugal collectors use cyclonic action to separate

particles from the gas stream. In a typical cyclone, the gas stream enters a vessel at an angle and

is spun rapidly. The centrifugal force created by the circular flow throws the particles toward the

wall of the cyclone. After striking the wall, these particles fall into a hopper located beneath the

cyclone. Single-cyclone separators create a dual vortex to separate coarse particles from fine. The

main vortex spirals downward and carries most of the coarser dust particles. The inner vortex

created near the bottom of the cyclone spirals upward and carries finer dust particles. Multiclones

consist of a number of small diameter cyclones, operating in parallel and having a common gas

inlet and outlet. Multiclones operate on the same principle as cyclones by creating a main

downward vortex and an ascending inner vortex. Multiclones are more efficient than single

cyclones because they are longer and smaller in diameter. The longer length provides longer

residence time while the smaller diameter creates greater centrifugal force. These two factors

result in better separation of dust particulates. The pressure drop of multiclone collectors is higher

than that of single-cyclone separators. Typical removal efficiency is 80%.

Method 5. Wet Suppression – Fine mists of water applied to dust generating sources, such as

bulk material drop points, reduce dust emissions by impacting small particulates with water. The

wetted particulate becomes heavier and quickly settles out of the air, reducing airborne dust.

Alternatively, material may be thoroughly wetted prior to handling, which suppresses the

generation of dust when the material is disturbed. Typical removal efficiency is 50% - 90%.

Method 6. Covered Conveyors and Enclosed Transfer Points – Covered conveyors are an

application of partial enclosures and wind screens that are specific to conveyor systems. The

conveyor hoods work to help prevent wind from lifting dust particles from materials being

transported on the conveyor. Similarly, enclosed transfer points work to isolate material drop

points between conveyors from the surrounding weather conditions. Enclosed transfer points are

typically designed with minimized material drop heights to reduce dust generated by materials

being transferred.

Potential control alternatives were ranked for effectiveness in controlling PM10/PM2.5 emissions

from the material handling and screening operations. The baghouse is the top control option.

Step 4: Evaluate the Most Effective Controls and Document Results

Fabric filters or baghouses are an industry standard for PM10/PM2.5 control in many applications.

Baghouses are capable of up to 99.9% removal efficiencies. As described in the previous

subsection, a dust collection system is specified to achieve a specific outlet concentration, i.e.,

absolute efficiency. Baghouse removal efficiency is relatively level across the particle size range

so that excellent control of all particle sizes can be obtained. Baghouses are not sensitive to

variations in loading rates.

Review of the EPA RACT/BACT/LAER Controls (RBLC) database confirms that the use of a

fabric filter constitutes BACT. An absolute control efficiency of 0.0025 grains per dry standard

cubic foot compares favorably to the most recent DRI project, where a venturi scrubber option

achieving 0.0075 grains per dry standard cubic foot was determined to meet BACT.

Step 5: Select BACT

Based on the top-down BACT analysis, the best or “top” available control technology is the use

of covered conveyors for material transfer, and a fabric filter baghouse achieving 0.0025 grain per

dry standard cubic foot control of PM10/PM2.5. The screening building will be vented to a baghouse

for collection of fines. Once pellets have entered the production building, emissions are captured

and plant air exits through the EAF baghouse.

Covered conveyors and enclosed transfer points will be installed to limit emissions from material

handling activities outside of buildings where individual dust generation sources are small and

scattered across a wide area. In summary, BACT consists of:

• Covered conveyors and transfer points

• At the tip area where pellets are loaded into the hoppers, dust suppression at the transfer

points, utilizing a suppressing spray to blanket and suppress airborne particulate matter.

• Fabric filter (baghouse) with a design efficiency of 0.0025 grain per dry standard cubic

foot on PM10 and PM2.5.

4.4.3 Roadways and Parking Areas

Petmin’s facility is located on a leased site within the perimeter of an existing, permitted industrial

facility. Facility roadways are therefore contiguous with other controlled roads.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Commercial Dust Suppressants – Chemical surface stabilizers act to agglomerate

particles on road surfaces. These larger particles are less likely to become airborne due to wind or

passing vehicles. Surface stabilizers must be reapplied periodically as they are broken down by

traffic and rain events. Efficiencies of 95% can be achieved.

Method 2. Wet Suppression – The use of water suppression can control PM10/PM2.5 emissions

by up to 95%, although it must be applied more frequently than chemical dust suppressants. Water

is typically applied using a water truck, i.e., a truck-mounted sprayer.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

1. Commercial Dust Suppressants - 95%

2. Wet Suppression - 95%

Potential control alternatives were ranked equally effective in controlling PM10/PM2.5 emissions

from the roadways and parking areas.

Step 4: Evaluate the Most Effective Controls and Document Results

Commercial dust suppressants and Wet suppression are equally effective in controlling fugitive

dust from roadways. The main differences between the options are the required frequency of

reapplication. Water costs less and has lower potential for soiling vehicles and contaminating

nearby surface water.

Step 5: Select BACT

Based on the top-down BACT analysis, the best available control technology is wet suppression,

due to having comparable control efficiency, fewer possible environmental issues, and lower cost.

In summary, BACT consists of applying wet suppression to roadways, if required, based on routine

visual assessments.

4.4.4 Fuel Burning Equipment (Process Gas Heater, Ladle Preheat, Flare, and Startup Boiler

The listed equipment burns natural gas as the primary fuel. Natural gas is recognized as a “clean”

fuel with respect to potential emissions of particulate matter. The process gas heater and flare also

burn some process gas, consisting principally of hydrogen and carbon monoxide. All will emit

particulate matter as the products of incomplete combustion. Larger carbon compounds due to

incomplete combustion are typically filterable. Smaller organics that are not completely

combusted can be gaseous at typical flue gas temperatures, and later condense after being emitted

by the source. Control technologies that rely upon direct filtration or capture of solid particles may

be ineffective at controlling condensable particulate matter. In the case of natural gas combustion,

half or more of total particulate is generally assumed to be condensable.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Good Combustion Practices – Good combustion practices are used to reduce

emissions of PM10/PM2.5, as well as other pollutants, by optimizing conditions in the combustion

zone of a fuel burning source. Particulate emissions from the burning of fuels are usually due to

the incomplete combustion of hydrocarbon fuel but may also be due to inorganic particles present

in the fuel as an impurity. Good combustion practices typically entail introducing the proper ratio

of combustion air to the fuel, maintaining a minimum temperature in the firebox of the combustor,

or a minimum residence time of fuel and air in the combustion zone. By employing good

combustion practices, both the filterable and condensable fractions of particulate matter normally

emitted may be greatly reduced.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

1. Good Combustion Practices - 50%

Page 125: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

- 70 -

A review of the potential control options, and combination of options, was conducted to identify

the most effective strategy for controlling PM10/PM2.5 emissions from the combustion of natural

gas. Petmin has identified good combustion practices as the most effective and technically feasible

control option.

Step 4: Evaluate the Most Effective Controls and Document Results

Good combustion practices can be effective at reducing PM10/PM2.5 emissions generated from

the incomplete combustion of hydrocarbon fuels, because the technique limits both the filterable

and condensable fractions of particulate emissions. Because of this property unique to the control

technology set, and the fact that the majority of particulates generated by natural gas combustion

are condensable, good combustion practices ranks the highest of the identified control

technologies.

Step 5: Select BACT

Based on the top-down BACT analysis, the best available technology for controlling PM10/PM2.5

from the fuel burning equipment is the use of natural gas, supplemented by hydrogen and carbon

monoxide from recycled gas, and good combustion practices. Petmin will maintain good

combustion practices to control the generation of PM10/PM2.5 emissions that could otherwise occur

from incomplete combustion of natural gas and process gas.

4.4.5 Emergency Engines, Fire Pumps, and Black Start Generator

The listed equipment burns ultra-low sulfur diesel fuel as the primary fuel. Larger carbon

compounds due to incomplete combustion are typically filterable. Smaller organics that are not

completely combusted can be gaseous at typical flue gas temperatures, and later condense after

being emitted by the source. Control technologies that rely upon direct filtration or capture of

solid particles may be ineffective at controlling condensable particulate matter.

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Good Combustion Practices – Good combustion practices are used to reduce

emissions of PM10/PM2.5, as well as other pollutants, by optimizing conditions in the combustion

zone of a fuel burning source. Particulate emissions from the burning of fuels are usually due to

the incomplete combustion of hydrocarbon fuel, but may also be due to inorganic particles present

in the fuel as an impurity. Good combustion practices typically entail introducing the proper ratio

of combustion air to the fuel, as well as proper design and maintenance of equipment. By

employing good combustion practices, both the filterable and condensable fractions of particulate

matter normally emitted may be greatly reduced.

Method 2. Emergency Generator Classification – The proposed diesel generators and fire

protection pumps are classified as emergency generators. The black start generator is not defined

as an emergency generator but will operate only during startup from a cold condition. Each of the

units is limited by federal requirements to operate no more than 100 hours per year for maintenance

and readiness testing. Otherwise, operation is limited to emergency conditions or a black start

condition. These limitations effectively minimize PM10/PM2.5 emissions.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

1. 1. Limitation on Hours for Maintenance and Readiness Testing 98.8%

(100 hours out of 8,760)

2. Good Combustion Practices – 50%

A review of the potential control options, and combination of options, was conducted to identify

the most effective strategy for controlling PM10/PM2.5 emissions from the combustion of diesel

fuel. Petmin has identified good combustion practices, in combination with very limited operation,

as the most effective control option.

Step 4: Evaluate the Most Effective Controls and Document Results

Good combustion practices can be effective at reducing PM10/PM2.5 emissions generated from

the incomplete combustion of hydrocarbon fuels, because the technique limits both the filterable

and condensable fractions of particulate emissions. Operating fewer than 100 hours per year for

maintenance and readiness testing results in zero emissions approximately 99% of the time.

Step 5: Select BACT

Based on the top-down BACT analysis, the best available technology for controlling PM10/PM2.5

from the generators is good combustion practices, combined with limited operation. Petmin will

maintain good combustion practices in all fuel burning equipment to control the generation of

PM10/PM2.5 emissions due to incomplete combustion of diesel fuel.

4.4.6 Storage Piles

Petmin will have storage piles of two materials: Remet (partially-reduced iron ore pellets, which

are taken back to the pellet loading hopper; and pig iron castings. As described previously in this

report, Remet is an off-specification, partially reduced iron that is produced in extremely limited

quantity, ideally only during plant startup/shutdown. As shown in the calculations provided with

this application, the emissions from storage piles are minimal, and qualify in Ohio rules as “de

minimis” units.

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 72 -

Steps 1 & 2: Identify all Control Technologies and Eliminate Technically Infeasible Options

Method 1. Reduction of Fines – Fugitive dust is a result of fine particulate in the stored material

being entrained in the air as a result of pile disturbance and/or high wind conditions. If there are

no particles light enough to be windborne, there will be no emissions.

For the materials stored by Petmin, Remet has had fines removed from the pellets before

processing; pig iron castings are cooled/solidified metal. Remet is only produced during upset and

startup/shutdown conditions, which will be minimized to the extent possible.

Method 2. Commercial Dust Suppressants – Chemical surface stabilizers act to agglomerate

particles on storage piles. These larger particles are less likely to become airborne due to wind or

disturbances. Surface stabilizers must be reapplied periodically after rain events and as stock is

moved from the piles. Efficiencies of 95% can be achieved.

Method 3. Wet Suppression – The use of water suppression can control PM10/PM2.5 emissions

by up to 95%, although it must be applied more frequently than chemical dust suppressants. Water

is typically applied using a sprayer or sprinkler.

Step 3: Rank Remaining Control Technologies by Control Effectiveness

1. Reduction of Fines – 99%

2. Commercial Dust Suppressants - 95%

3. Wet Suppression - 95%

A review of the potential control options, and Petmin’s stockpiled materials, was conducted to

identify the most effective strategy for controlling PM10/PM2.5 emissions from the storage piles.

All listed options are comparable.

Step 4: Evaluate the Most Effective Controls and Document Results

Reduction of fines is the first option, if it can be achieved, due to its simplicity. Commercial

dust suppressants and Wet suppression are equally effective in controlling fugitive dust from

storage piles. The main differences between the latter two options are the required frequency of

reapplication. Water costs less and has lower potential for contaminating nearby surface water.

Step 5: Select BACT

Based on the top-down BACT analysis, the best available control technology for storage piles is

the reduction of fines in the stored material. As a contingency, wet suppression is preferred to

other dust suppressants due to having comparable control efficiency, fewer possible environmental

issues, and lower cost. In summary, BACT consists of:

Page 128: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

• Minimal fines in stored materials

• Wet suppression is not expected to be required based on the materials and quantities in

storage piles.

4.4.7 Cooling Tower

The cooling towers are equipped with drift eliminators. Emission calculations show that total PM

emissions are 0.019 tons per year. Control beyond the use of drift eliminators is not feasible.

BACT is the use of drift eliminators.

4.5 Greenhouse Gases (GHG)

GHG are minimized from the PGH by use of clean-burning natural gas as fuel; good combustion

practices, by optimizing the air-to-fuel ratio; operating the burners in a manner to obtain the

maximum heat output per unit of carbon combusted; and recovering/recycling unburned reduction

gases in the reducing gas reconditioning loop, including methane.

The technology used in the reducing gas reconditioning loop, chemical absorption, could, in

theory, be applied to the PGH waste gas stream. However, unlike the reconditioning loop, the

exhaust gas from the PGH does not contain the recoverable CO and H2 that can be reused in the

process, which made CO2 separation an economically viable possibility. Chemical absorption is

not an “available technology” for a simple combustion unit.

Calcium cycle separation uses quicklime (CaO) to capture CO2 to form limestone, which can be

reheated to release CO2 in a concentrated stream and regenerating the quicklime for reuse. This

technique is in the R&D phase and is not considered an “available” technology.

A remaining technology to consider is carbon capture and sequestration (CCS). In theory, CCS

involves capturing and concentrating CO2 from its source by separating it from the PGH gas

stream, then transporting it, then storing it away from the atmosphere for a long period of time,

such as in underground geological formations or in the deep ocean. CCS is not an “available

technology” for use to Petmin to capture and sequester the CO2 from the PGH.

Petmin’s end product, nodular pig iron, is purified to a degree that requires less processing by its

end users. Fundamentally, the production of NPI reduces GHG downstream.

With no technically feasible options available BACT consists of:

• Good combustion practices

• Production of NPI, a high-purity product that results in lower GHG emissions by end users

It should be noted that the Petmin project planners and designers maintain a long-range objective

to sell the CO2-rich waste gas from the gas conditioning loop to a gas processing plant owned and

operated by an independent third party. This novel, innovative approach is not a demonstrated

technology in DRI production, and is, therefore, above and beyond BACT-level controls.

However, if and when demonstrated to be practicable, it is possible that a 50% GHG reduction

could be achieved through innovative separation of CO2 sold as a feedstock to a third-party

processor.

4.5.2 Other Emissions Units

Carbon present in the DRI melt or from sublimation/oxidation of the electrodes is inherent to the

process. GHG formation is minimized by the use of electrical energy as the heat source;

conservation of energy by well-designed refractory and good operating practices. No add-on

controls or other technology (as described in the previous section) are technically feasible.

The remaining emissions units are relatively small combustion units that are either:

• Fueled with natural gas, and operated with good combustion practices; or

• Emergency or black start-up engines with minimal expected run time and

correspondingly minimal GHG emissions.

No additional control measures are technically feasible for these units.

4.6.1 Electric Arc Furnace

The Tenova EAF design engineering team provided the following information to establish BACT

for CO emissions.

Description

The EAF is a cylindrical vessel with a diameter of 21 feet. The walls of the furnace are completely

refractory lined. The hearth or bottom of the furnace is thick refractory, and the roof is water-

cooled. Carbon electrodes pass through openings at the top of the furnace and are 24 inches (610

mm) in diameter. Electric current is carried from a transformer, through support arms, and into the

Page 131: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

- 76 -

electrodes where the metallic bath completes the electric circuit. The electrodes deliver the power

to the furnace in the form of an electric arc between the electrode and the furnace charge and bath.

The arc itself is a plasma of hot, ionic gasses in excess of 6,000°F (3,300°C).Unlike most EAFs,

which are charged with steel scrap and sometimes with Direct Reduced Iron (DRI) to produce

liquid steel, this novel unit is designed to be fed with high carbon DRI to produce hot pig iron.

Pig iron is an alloy of iron and carbon with higher carbon content than steel. Therefore, the process

is much higher in carbon than an EAF producing steel. Unlike most EAFs producing steel, there

is no oxygen injection; by contrast, the Petmin EAF uses a reducing atmosphere. Under this

condition CO is the combustion product of carbon because of the low amount of oxygen. CO is

emitted as a byproduct.

CO Emissions

In the EAF, possible sources of the carbon are from the DRI, possible additions of carbon, and the

furnace electrodes. More specifically, the EAF generates CO as a result of oxidation of carbon that

is introduced into the furnace charge to refine the metal bath. Sublimation and subsequent

oxidation of the carbon electrode is also expected to occur. Several operating parameters impact

CO emissions, including the amount of carbon, oxygen, temperature within the EAF, composition

of the DRI charged, and operating practices.

Step 1: Identify all Control Technologies

Possible alternatives for control of CO emissions from the EAF were identified as follows:

• Flare CO Emissions

• DEC Controls

• Post Combustion Reaction in DEC Circuit and Chamber

• Oxygen Injection

• CO Oxidation Catalyst and Catalytic Incineration

• EFSOP™ (Expert Furnace System Optimization Process)

Step 2: Eliminate Technically Infeasible Options

Flaring

Flaring of blast furnace gases and Basic Oxygen Furnace (BOF) gases is quite common in the iron

and steel industry. Flare stacks are used to burn off non-recoverable flammable gases. However,

the flaring option is used when the heating value and the auto-ignition temperature of the off-gases

are within their flammability limit. In the exhaust gas from the Petmin EAF, the CO concentration

is a few thousand ppm, much lower than the concentration required for flaring. (The lower

Page 132: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

- 77 -

flammability limit for CO is 125,000 ppm.) Direct flaring is not a technically feasible option in

this case. Further, based on review of available information, there is no known application of

flaring raw EAF exhaust gases. This technology was eliminated from further consideration.

DEC Controls

A Direct Shell Evacuation Control (DEC) system is comprised of a water-cooled duct connected

to the EAF via the furnace roof’s “fourth hole”. The duct is connected to the melt shop canopy

collector system. During melting and refining, a neutral or slightly negative pressure is maintained

in the furnace to withdraw exhaust gases through the DEC. Where the DEC duct meets the “fourth

hole”, an adjustable gap exists that allows combustion air to enter, providing oxygen to oxidize

CO and any other combustible species. The DEC system allows excellent emissions capture,

promotes combustion of CO and combustibles to a certain extent, and requires the lowest air

volume compared to other EAF capture devices.

The capability is limited due to the cyclic operating schedule (i.e., hot-cold cycling). Thermal

oxidation of CO to CO2 requires temperatures above 1,200°F (650°C). In the Petmin EAF, exhaust

gas temperatures will fluctuate during each melt and often drop below 1,200°F (650°C). It is

estimated that this would occur for several minutes during each melt. The minimum temperature

that would be encountered is estimated to be approximately 350°F (180°C). Thus, during these

periods, the thermal destruction efficiency would be expected to decrease, resulting in significant

CO emissions. Consequently, this control alternative is considered reasonably efficient for

oxidation of residual concentrations of CO but with limitations due to the temperature cycling

intrinsic to the melt cycle.

Post Combustion Reaction in DEC Circuit and Chamber

The principle of destruction in this technology is to raise the EAF exhaust gases in the primary

suction circuit with auxiliary fuel firing to a sufficiently high temperature for a minimum time to

facilitate oxidation through post combustion. Combustion chambers are usually utilized, and their

configuration must provide effective mixing in the chamber with an acceptable residence time.

Post combustion naturally takes place while combustion air is drawn into the circuit and reacts

with CO and other combustibles contained in the offgas.

Again, the reaction depends on various parameters – most importantly, gas temperature and

combustible content. (See also the discussion of “Oxygen Injection” in the next subsection).

Effectively controlling the reactions would require post–combustion system, including burners and

associated controls that can assure ignition of the gas mixture whenever necessary. Based on a

review of available resources, this technology has not been applied on EAFs in the United States;

also, the feasibility of these units to significantly reduce CO emissions, without resulting in severe

Page 133: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

operation problems, is unknown. Such units are expected to consume large quantities of natural

gas and oxygen, resulting in excessive annual operating costs and increased NOx emissions.

Precise performance guarantees are difficult to estimate because of the lack of operating

experience. Further, due to the heat and particulate loading, the burners that supply the auxiliary

fuel would have a short life expectancy and may sustain severe maintenance and reliability

problems.

Additionally, a single or multiple duct burner system would not be able to heat the relatively cool

gases from the EAF during cold cycling.

Potentially, there are three locations where post combustion chambers can be installed, (i.e,

upstream or downstream the mixing point of the DEC duct with the main duct, or downstream

of the baghouse).

• Locating a post combustion chamber upstream of the mixing point of the DEC circuit with

the main duct would take advantage of the elevated temperatures in the gas stream.

However, at this location, the post combustion chamber would be subject to extremely high

particulate loading. The units would be exposed to foul frequently from the particulate

accumulation, resulting in severe maintenance and reliability concerns. This option would

be technically difficult to implement and operate, and is considered infeasible.

• Locating a post combustion chamber downstream of the mixing point of the DEC duct with

the main duct would be at a much lower temperature in the exhaust gas stream.

Nevertheless, at this location, the post combustion chamber would still be subject to high

particulate loading, with the same fouling, maintenance and reliability concerns. Moreover,

the higher gas flow at lower temperatures would greatly increase the auxiliary fuel

requirements. Combustion of additional fuel will result in increases in NOx emissions.

Finally, after post-combustion the gas would need to be cooled down again, in order to be

filtered in the baghouse. This option is technically infeasible.

• The post combustion chamber could be installed downstream of the EAF baghouse.

However, at this location fuel consumption and NOx emission concerns would be

considered extreme to a point of practical infeasibility.

Oxygen Injection

A theoretical means of reducing CO would be oxygen injection at the entrance of the ductwork to

increase oxidation of the available CO to CO2. Oxygen injection directly into the furnace to reduce

CO emission levels is an experimental operating practice in Europe used to increase the heat input

to the melt, but the practice has not been demonstrated to reduce CO emissions.

Typically, as already described, the DEC system draws air into the duct, creating an oxygen-rich

mixture of EAF exhaust gases after the gap, where CO is naturally oxidized. The addition of

oxygen is expected to convert little if any CO to CO2. The capability is also limited due to the

cyclic operating schedule (i.e., hot-cold cycling). Thermal oxidation of CO to CO2 requires

temperatures above 1,200°F (650°C). Exhaust gas temperatures will fluctuate during each melt

and often drop below 1,200°F (650°C). It is estimated that this would still occur for several minutes

during each melt, although with a lower frequency and duration than in the DEC control case. The

minimum temperature that would be encountered is estimated to be approximately 350°F (180°C).

Thus, during these periods, the thermal destruction efficiency would decrease significantly,

resulting in elevated CO emissions.

This control alternative is not considered efficient and is eliminated from further consideration in

this analysis.

CO Oxidation Catalyst and Catalytic Incineration

Catalytic incinerators or oxidizers use a bed of catalyst that facilitates the overall combustion of

combustible gases. The catalyst increases the reaction rate and allows the chemical conversion at

lower temperatures than a thermal incinerator. The catalyst is typically a porous noble metal

material, which is supported in individual compartments in the unit. An auxiliary fuel-fired burner

ahead of the bed heats the entering exhaust gases to approximately 600°F (316°C) to maintain

proper bed temperature.

The temperature of the exhaust gases from the EAF will vary significantly during the various

stages of the heat (212° to 1,300° F, or 100° to 700° C). Thus, the temperature will be below the

minimum 500°F (260°C) threshold for effective operation of the catalysts during much of its

operation. In addition, the wide variation in temperature would make operation of a catalyst

impractical. Lastly, the particulate loading in the exhaust gas stream is anticipated to be too high.

Masking effects, such as plugging and coating of the catalyst surface, would almost certainly result

in impractical maintenance requirements, and would significantly degrade the performance of the

catalyst. Trace metals that could occasionally be present in the exhaust stream are generally

considered poisons to catalysts and deactivate the available reaction sites on the catalyst surface.

PM can also build up on the catalyst, effectively blocking the porous catalyst matrix and rendering

the catalyst inactive. In cases of significant levels of poisoning compounds and particulate loading,

catalyst replacement costs are significant.

As in the thermal incineration (post-reaction chamber) discussion, there are two potential locations

where the catalyst bed could be installed, i.e. upstream or downstream of the EAF baghouse. For

the same reasons discussed earlier (e.g., fouling due to PM), the upstream location is considered

technically infeasible.

Alternatively, the catalyst could be installed downstream of the EAF baghouse. However, even at

this location, fouling due to PM could occur, and further, the exhaust would be at a much lower

temperature and with highly increased gas flow. These factors would greatly increase the auxiliary

fuel requirements. The associated combustion of additional auxiliary fuel would result in an

overwhelming increase in natural gas consumption, resulting in increases in emissions (especially

NOx) to the atmosphere.

Based on a review of the available information resources, there is no application of a catalytic

incineration system or an oxidation catalyst to control CO emissions from an EAF. This control

option, while theoretically feasible, is considered to be infeasible as a practical matter to install a

catalytic thermal oxidizer on a variable exhaust stream of several hundred thousand cubic feet per

minute exhaust flow, for CO control. With no known applications for use on an EAF, this option

is eliminated from consideration.

EFSOP™ (Expert Furnace System Optimization Process)

EFSOP® is a burner optimization label that Tenova uses to sell their burner and control systems.

It is an off-gas based process control system which measures off-gas from the melting process on

a continuous basis and uses the output in conjunction with a computer model to optimize furnace

operations and reduce overall conversion costs. A conditioning system cleans the offgas sample

and a portion of it is analyzed for carbon monoxide (CO), carbon dioxide (CO2), hydrogen (H2)

and oxygen (O2).

This technology has been established and Tenova has several installations operating worldwide,

which have measured and analyzed data from millions of heats. In steel producing EAFs, typical

combustion efficiency of CO conversion to CO2 varies from 25-70% for the heat cycle.

The EFSOP® system provides on-line measurements in real-time of what is occurring as the

furnace emissions are exhausted. An added advantage is that the system can be used to control

post-combustion systems installed into the furace. This optimizes furnace combustion, increases

production and saves energy. Steelmakers have reported energy savings of 20kWh/ton of steel and

tap-to-tap time reductions of 2 to 3 minutes with EFSOP®.

The EFSOP® system analyzes the furnace off-gas just before the combustion gap to quantify the

amount of carbon monoxide (CO) in the off-gas. The CO results from the incomplete combustion

of oxygen and fuel in the furnace shell. Some furnace practices and charge mixes also cause high

levels of hydrogen (H2) in the off-gas streams. Together, these combustible gases can make up

over 30 per cent of the furnace offgas and they represent a tremendous loss of energy in the

steelmaking process.

The EFSOP® system allows the steelmaker to tailor the operation of the DEC system to match the

actual requirements of the process. In steel producing EAFs, usually provided with an oxygen

injection system and burners, the continuous fume analysis of the furnace off-gas allows the

steelmaker to conduct controlled post-combustion into the furnace, before it escapes into the DEC

system, thus capturing some of the energy that would be otherwise lost in the off-gas.

In the Petmin EAF, designed for DRI consumption, neither oxygen injection nor oxy-fuel burners

are present or desirable. While the EFSOP® system could be used to analyze the off-gas, there are

no corresponding parameters for optimizing key parameters for CO control. Thus, this technology

would not be effective for the Petmin EAF, and is eliminated from consideration.

DEC Controls is the only feasible control option identified.

The right-hand column indicates what the ton-per-year limitation would be for Petmin, if it had

the pound CO per ton metal produced allowable value in the listed permit.

AP-42 lists several emission factors for CO from EAFs that range from 1.0 to more than 3.8 pounds

CO per ton. This wide variability is not explained, but is likely a result of factors that include:

• Amount of carbon in the raw melt, and/or charged;

• The amount of arc drawn into the EAF

• The effectiveness of the slag practice

• The number of charges

• EAF temperature, and

• Production rate

Step 5: Select BACT

The use of a DRI fed EAF in hot metal production is a novel technology. Proprietary emissions

modeling by the design engineering team indicate that the value corresponding to 1.8 pounds per

ton of product as indicated in the AP-42 rating “B” can be achieved with the use of a DEC Control

system. This emission limitation clearly indicates satisfactory environmental performance when

compared to the “similar” sources listed above.

Petmin also suggests a term in the PTI that the DEC system must be operating at all times the EAF

is in operation.

4.6.2 Other Emissions Units

The remaining emissions units are either:

• Combustion units using natural gas as fuel. CO formation is minimized following good

combustion practices. No add-on CO controls are in the realm of feasibility for these clean-

burning units; or

• Emergency use only or black startup engines with operation limited to 100 hours per year

for maintenance and readiness testing, as well as their emergency or black-start only

functions. Federal rules limit operation time and corresponding emissions of CO to

minimal annual values. Controls beyond these limitations would not be feasible.

5.0 Ambient Air Quality Analysis

As described in previous sections of this report, Petmin is proposing to construct and operate a

new facility located in Ashtabula County. The new facility will be located within the Kinder

Morgan (KM) Pinney Dock facility at 1149 East Fifth Street, Ashtabula, Ohio.

The Petmin facility is a new major stationary source. The Ashtabula area is presently designated

as in attainment for all pollutants. The potential emissions of NOx and CO associated with the

proposed new facility are greater than the major source threshold (100 tpy for a source in the 28

categories listed) in Prevention of Significant Deterioration (PSD) rules; therefore, the Project will

be subject to PSD requirements.

The potential emissions of SO2 and VOC will be below the significance thresholds listed in the

PSD rules and Ohio EPA Modeling Guidance document. PM10, and PM2.5 exceed the modeling

significance thresholds. These pollutants will be modeled in addition to NOx and CO. No air toxic

(listed in OAC §3745-114) exceeds the modeling threshold.

As part of the PSD permitting process, an air quality impact analysis is required to demonstrate

that the proposed emissions from the project (i.e., that includes the above-listed emissions units),

in conjunction with emissions from other existing off-site sources, will not cause any exceedances

of applicable National Ambient Air Quality Standards (NAAQS) for NO2, CO, PM10, and PM2.5.

Further, the study will demonstrate that the emissions associated with this project will not exceed

the available PSD increment.

The modeling study was performed by AYER Quality Engineering LLC (AYER) of Cincinnati,

OH. Joseph N. Hollowell, P.E. performed the analysis, with review by Matthew Ayer, Senior

Consultant.

The modeling study was performed following the procedures in Guideline for Air Quality Models15

(Supplement W to 40 CFR §51) and Engineering Guide #69: Air Dispersion Modeling Guidance,16

Ohio EPA Division of Air Pollution Control, Revised November 14, 2018. As described in more

detail in subsequent sections to this report, the U.S. EPA AERMOD model was selected for this

study.

5.1 Site Area Characteristics

Certain site area characteristics, including wind climatology, land use classification, and terrain

analysis, are necessary components of the dispersion modeling analysis.

5.1.1 Wind Climatology

The Petmin MPI manufacturing plant will be located in Ashtabula (Ashtabula County), in

northeastern Ohio, on the Pinney Dock Terminal property on Lake Erie in the City of Ashtabula.

The facility is approximately 48 miles (77 km) northeast of downtown Cleveland, and

approximately 34 miles (54 km) southwest of Erie, PA International Airport. Terrain in the

vicinity is flat to rolling, with elevations ranging from 525 feet (160 meters) to 650 feet (198

meters) within 5 km of the facility.

Figure 5 is a five-year composite wind rose generated from meteorological data provided by Ohio

EPA.17 The figure graphically summarizes the frequencies of wind speeds and directions.

5.1.2 Land Use Classification

Air dispersion models require that the land use in the vicinity of the source be classified as either

URBAN or RURAL so as to assign the proper dispersion coefficients. In modeling studies, a

binary typing scheme can be used to delineate urban versus rural land use in the vicinity of the

project. The predominant land use is then selected in the model (RURAL or URBAN). In this

particular case, a detailed analysis was not necessary. RURAL dispersion coefficients were

selected because it is immediately apparent that the land surrounding the site is predominantly

undeveloped rural areas and Lake Erie. Figure 8 shows a Google Earth image18 of the where the

facility will be located.

Figure 8: Google Earth Image of the Location of the Proposed Petmin Facility

5.1.3 Terrain Analysis

National Elevation Data (NED) digital terrain data were used in the model, obtained from the

United States Geological Survey (USGS) website as 1/3 arc second series topographic map data.

AERMAP is used with the NED digital terrain data files to establish receptor coordinates,

elevations, and “hill heights” (height scale) for model input.

5.2 Pre-Application Air Quality Monitoring

Ohio EPA collects continuous ambient monitoring data and has concurred that it is representative

for the site and fulfills the pre-application monitoring requirement for this PSD analysis. The Ohio

EPA has discretionary authority to exempt an applicant from performing onsite meteorological

monitoring if either (1) the predicted ambient impact caused by the modification, i.e., the highest

concentrations are less than the prescribed significant monitoring value (Table 18). As shown in

Section 5.5 and Table 24, the modeled annual NO2 and 8-hour CO concentrations from Petmin are

both below the Significant Monitoring Concentrations. The NO2 data collection site (Monitor ID

Number 39-035-0073) is located in the city of Cleveland approximately 77 kilometers (48 miles)

distant from Petmin. The ozone data collection site (Monitor ID Number 39-007-1001) is located

obtained from a nearby monitor in Cleveland (GT Craig NCore, Monitor ID Number 39-035-

0060).

Missing data were substituted using the averages of the surrounding hourly values for gaps of less

than five hours. Gaps of greater than five hours were filled in using one of two ways. For the five

ozone data gaps greater than five hours, the following substitutions were used:

• 85 hours in 2015 from August 21 at 15:00 to August 25 at 3:00. These values were filled

in using the data from the same hours from 2016.

• 22 hours in 2017 from March 8 at 14:00 to March 9 at 11:00. These values were filled in

using the data from the same hours from 2016.

• 13 hours in 2017 from March 23 at 1:00 to March 23 at 13:00. These values were filled

in using the data from the same hours from 2016.

• 19 hours in 2017 from November 8 at 21:00 to November 9 at 15:00. These values were

filled in using the data from the same hours from 2016.

• 27 hours in 2017 from November 27 at 10:00 to November 28 at 12:00. These values were

filled in using the data from the same hours from 2016.

For each NO2 gap greater than five hours, the 98th percentile value for the particular season-hour

was used to fill in the missing data. For example, if Hour 6 in March were missing, then the 98th

percentile concentration of Hour 6 for all days in the Spring season was used. Continuing this

example, if there were 92 Hour 6 values in the Spring season (March through May) for each year,

the 98th percentile value was calculated from these 92 values using the Microsoft Excel “percentile

function.” This procedure is followed for each of the four years. Then, the average of these four

98th-percentile values is input to the model to fill the gap.

Data gap-filling and calculation of season-hour concentrations were performed in Microsoft

Excel.™ These files have previously been provided to Ohio EPA as supplements to the air

dispersion modeling study protocol.

AERMOD20 has several options for inputting background concentration data. For ozone, the

hourly concentration data file was used. AERMOD then merges (or “pairs”) the hourly data with

the meteorological data.

For NO2 background data, EPA guidance stipulates the use of average concentration data, with

several averaging options. For this study, the hourly background data for NO2 was converted to a

season-hour-average table for use in the model. In this approach, the hourly data is converted by:

and then

• Averaging over the four-year period, 2014-2017, of data to obtain a single value for each

hour in each season.

there is a significant impact to air quality. If the modeling indicates a significant impact, the impact

area will be determined. The impact area is defined as the circular area with a radius extending

from the source to (1) the most distant point where approved dispersion modeling predicts a

significant ambient impact will occur, or (2) a modeling receptor distance of 50 km, whichever is

less. If the preliminary analysis indicates a significant increase may occur, then a full impacts

analysis is required. The full impact analysis requires modeling all sources within 50 km that may

impact ambient concentrations within the significant impact area.

5.4.1 AERMOD Modeling System

The AERMOD computer model was selected for the air dispersion modeling study. The American

Meteorological Society/Environmental Protection Agency Regulatory Model Improvement

Committee (AERMIC) was formed to introduce state-of-the-art modeling concepts into the EPA's

air quality models. Through AERMIC, the AERMOD modeling system was selected to

incorporate air dispersion based on planetary boundary layer turbulence structure and scaling

concepts, including treatment of both surface and elevated sources, in both simple and complex

terrain.

AERMOD is a steady-state plume dispersion model for assessment of pollutant concentrations

from a variety of sources. AERMOD simulates transport and dispersion from multiple point, area,

or volume sources based on an up-to-date characterization of the atmospheric boundary layer.

Sources may be located in rural or urban areas, and receptors may be located in simple or complex

terrain. AERMOD accounts for building wake effects (i.e., plume downwash) based on the Plume

Rise Model Enhancements (PRIME) building downwash algorithms. The model employs hourly

sequential preprocessed meteorological data to estimate concentrations for a broad range of

averaging periods, including one hour, one year, and multiple years. AERMOD is designed to

operate in concert with two pre-processor codes: AERMET, which processes meteorological data

for input to AERMOD, and AERMAP, which processes terrain elevation data and generates

receptor information for input to AERMOD.

AERMOD, contained in the commercially available Beeline Software package (BEEST),21 was

used for this analysis. This software is updated with the most recent version of the AERMOD

dispersion model and input data preprocessors, as follows:

• AERMOD version 19191

• AERMAP version 18081

• AERMET version 9191

• AERMINUTE version 15272

• AERSURFACE version 13016

The following options were used:

• Regulatory default options with the Tier 3 OLM option selected for NO2

• Terrain heights with intermediate terrain processing

• Building downwash

5.4.2 Receptor Grid

The entire KM Pinney Dock site is restricted from public access, by a combination of Lake Erie

docks, with the land perimeter entirely fenced, with a security gate at the main entrance. This

fenceline is used for the modeling study. A receptor grid was established, with receptors placed

along the property line spaced 25 meters apart. The NED data was obtained in GeoTIFF22 files

that make up a 50 km box surrounding the Petmin facility. Receptors for modeling against the

Significant Impact Levels (SIL) were then established onto a rectangular (Cartesian) grid as

follows:

• Spaced 50 meters apart outside the property line, out to a distance of 1 km from the property

line;

• Spaced 100 meters apart up to a distance of 2 km from the property line;

• Spaced 250 meters apart up to a distance of 5 km from the property line;

• Spaced 500 meters apart up to a distance of 10 km from the property line; and

• Spaced 1,000 meters apart up to a distance of 40 km from the property line.

AERMAP was used with the NED digital terrain data files to establish receptor coordinates,

elevations, and “hill heights” (height scale) for model input. Figure 9 shows this receptor grid.

5.4.5 Option Selected for One-Hour NO2 Modeling

The Tier 3 Ozone Limiting Method (OLM) was selected in AERMOD for modeling NOx

emissions. This method uses hourly ozone background data, aligned with the corresponding

season-hour NO2 background data.

As a result of change to 40 CFR Part 51, Appendix W - Guideline on Air Quality Models, the

OLM method is now available as a regulatory-default option within the EPA-preferred AERMOD

dispersion model. However, it must still be approved by U.S. EPA; therefore, a further justification

of the use of the OLM is included below.

In order to justify the use of OLM for the purpose of determining compliance with the Federal 1-

hour NO2 standard in this modeling study, the five requirements noted in Section 3.2.2.(e) are met

as follows:

Page 151: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

3.2.2 (e)(i). The model has received a scientific peer review;

As noted in a memorandum from EPA23 “Since AERMOD is the preferred model for dispersion

for a wide range of applications, the focus of the alternative model demonstration for use of the

OLM/PVMRM options within AERMOD is on the treatment of NOx chemistry within the model

and does not need to address basic dispersion algorithms within AERMOD.” Therefore, the

following will address the basic chemistry of each of the non-regulatory options.

Basic OLM Chemistry:

To provide some background, the following is a simplified explanation of the basic chemistry

relevant to the OLM. First, the relatively high temperatures typical of most combustion sources

promote the formation of NO2 by the following thermal reaction:

2 NO + O2 → 2 NO2

For “in-stack” formation of NO2, the OLM assumes a default 10% of the NOx in the exhaust is

converted to NO2 by this reaction, and no further conversion by this reaction occurs once the

exhaust leaves the stack. The remaining percentage of the NOx emissions is assumed to be nitric

oxide (NO).

As the exhaust leaves the stack and mixes with the ambient air, the NO reacts with ambient ozone

(O3) to form NO2 and molecular oxygen (O2):

NO + O3 → NO2 + O2 Oxidation of NO by ambient O3

The OLM assumes that at any given receptor location, the amount of NO that is converted to NO2

by this reaction is proportional to the ambient O3 concentration. If the O3 concentration is less

than the NO concentration, the amount of NO2 formed by this reaction is limited. If the O3

concentration is greater than or equal to the NO concentration, all of the NO is assumed to be

converted to NO2.

In the presence of radiation from the sun, ambient NO2 can be destroyed:

NO2 + sunlight → NO + O Photo-dissociation of NO2

As a conservative assumption, the OLM ignores this reaction.

Page 152: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Petmin USA Incorporated

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 97 -

Another reaction that can form NO2 in the atmosphere is the reaction of NO with reactive

hydrocarbons (HC):

NO + HC → NO2 + HC' Oxidation of NO by reactive HC

The OLM also ignores this reaction. This may be a non-conservative assumption with respect to

NO2 formation in urban/industrial areas with relatively large amounts of reactive HC emissions.

The chemistry for the OLM model has received scientific peer review as noted in "Sensitivity

Analysis of PVMRM and OLM in AERMOD".24 Also, the following documents posted on EPA’s

Support Center for Regulatory Air Modeling (SCRAM) website indicate that both models (OLM

and PVMRM) have been peer-reviewed:

of Short-Term NO2 Concentrations, Journal of the Air Pollution Control Association,

Contract No. 18-9010-12. MACTEC Federal Programs, Inc., RTP, NC.

These documents demonstrate that the OLM model has received appropriate scientific peer review.

3.2.2 (e)(ii). The model can be demonstrated to be applicable to the problem on a

theoretical basis;

The OLM model has been reviewed and the chemistry has been widely accepted by EPA as being

appropriate for addressing the formation of NO2 and the calculation of NO2 concentration at

receptors downwind. Additionally, the "Sensitivity Analysis of PVMRM and OLM in AERMOD"

report would indicate OLM/PVMRM provides a better estimation of the NO2 impacts compared

to other screening options.

The requirement of 3.2.2 (e)(ii) is: Can the model (OLM or PVMRM) be demonstrated to be

applicable to the problem on a theoretical basis? As noted in the document entitled “Sensitivity

Analysis of PVMRM and OLM in AERMOD”, “This report presents results of a sensitivity

analysis of the PVMRM and OLM options for NOx to NO2 conversion in the AERMOD dispersion

model. Several single source scenarios were examined as well as a multiple-source scenario. The

average conversion ratios of NO2/NOx for the PVMRM option tend to be lower than for the OLM

option and for the Tier 2 option or the Ambient Ratio Method (ARM2) which uses 0.5 as the

default minimum ratio and 0.9 as the default maximum ratio for both the annual average and the

hourly average. The sensitivity of the PVMRM and OLM options to emission rate, source

parameters and modeling options appear to be reasonable and are as expected based on the

formulations of the two methods. For a given NOx emission rate and ambient ozone concentration,

the NO2/NOx conversion ratio for PVMRM is primarily controlled by the volume of the plume,

whereas the conversion ratio for OLM is primarily controlled by the ground-level NOx

concentration.

Overall the PVMRM option appears to provide a more realistic treatment of the conversion of NOx

to NO2 as a function of distance downwind from the source than OLM or the other NO2 screening

options (Hanrahan, 1999a; Hanrahan, 1999b). No anomalous behavior of the PVMRM or OLM

options was identified as a result of these sensitivity tests.”

Based on this report for both OLM/PVMRM it appears to be applicable to the problem at hand,

i.e., the prediction of NO2 formation. As noted by the author, these options provide a more accurate

estimation of NO2 impacts compared to other screening options.

3.2.2 (e)(iii). The data bases which are necessary to perform the analysis are available

and adequate;

Five years (2013-2017) of both hourly processed meteorological data (Erie, PA/Buffalo, NY) and

concurrent hourly ozone monitoring data are available for this modeling application. Hourly ozone

concentrations from the Ashtabula monitoring station (19 km from the facility) will be input to

AERMOD for each year modeled (2013-2017). These data sets have been processed into

AERMOD-ready formats and are adequate for use with AERMOD-OLM.

The in-stack ratio that will be used for the sources in the model is the default ratio of 0.5 for all

sources, including the offsite sources.

3.2.2 (e)(iv). Appropriate performance evaluations of the model have shown that the

model is not biased toward underestimates;

Page 154: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

Petmin USA Incorporated

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 99 -

It has been shown in the sensitivity analysis (discussion on item 3.2.2 (e)(ii) above), that the OLM

provides similar but more conservative results than PVMRM. Therefore, it is reasonable to assume

that the OLM would also provide an unbiased estimate of concentration. (A formal, agency-

reviewed assessment of bias has not yet been published for the OLM option.)

3.2.2 (e)(v). A protocol on methods and procedures to be followed has been established.

The methods and procedures for conducting an assessment for determining compliance with the

federal 1-hour NAAQS are contained within this document. Specific OLM inputs are discussed

here. The in-stack ratio of NO2/NOx for all of the sources will be set to the default value of 0.5.

The default value of 0.9 will be used for the ambient equilibrium ratio in OLM.

5.5 Modeling Results – SIL

The model was executed for the Petmin emissions units. As shown in Table 24, the analysis

indicated that the predicted offsite impacts for just these emissions units were below the Significant

Impact Levels (SIL) for CO (1-hour and 8-hour) and annual PM10. NO2 (1-hour and annual), PM2.5

(24-hour and annual), and PM10 (24-hour) were all above the respective SIL. Since these impacts

exceeded the modeling significance level, i.e., the project results in a significant impact for these

pollutants. Therefore, a full impacts (a.k.a. cumulative or interactive) analysis is required to

demonstrate compliance with the 1-hour and annual NO2, the 24-hour and annual PM2.5, and the

24-hour PM10 NAAQS, including secondary formation of PM2.5.

The full impacts analysis for all of the pollutants and averaging periods was performed using the

40 km grid developed as described in Section 5.4.2. Secondary impacts of PM2.5 from NOx and

SO2 will be addressed later in the report in Section 5.10.

5.6 Full Impacts Analysis

A cumulative analysis for NO2 (1-hour and annual), PM2.5 (24-hour and annual), and PM10 (24-

hour only) was performed in accordance with Ohio EPA Modeling Guidance:

If maximum predicted impacts of a pollutant due to proposed emission increases from the

existing facility are at or above applicable SILs and there are nearby sources of that pollutant

that could significantly interact with emissions from the facility’s proposed modification, the

predicted air quality impacts from the existing facility as modified, along with predicted air

quality impacts from nearby significantly interacting sources, should be added to

representative background levels and compared to applicable NAAQS. If the results are below

applicable NAAQS, the facility, as proposed to be modified, is considered to be in compliance

with NAAQS for that pollutant.

5.6.1 Facility Emissions

The modeled emission rates for the new Petmin facility are shown in Tables 21 and 22 above. The

emission values are based on each emissions unit’s potential to emit (PTE) for both hourly and

annual emissions.

5.6.2 Nearby Significantly Interacting Sources

Ohio EPA was consulted to obtain the data for nearby sources relevant to the significant impact

area. A database of sources was obtained from the Ohio EPA25 and was filtered to extract those

sources located in Ashtabula, Geauga, Lake, and Trumbull Counties. The database included

emission rates and stack parameters for most of the sources.

For those sources which will be included in the model that had missing information, an additional

request was made to Ohio EPA and the missing information was provided via email26.

As confirmed with Ohio EPA, the only PSD source in the vicinity of Ashtabula County is the

Cristal USA Inc., Ashtabula Complex Plant 1 (Facility ID: 0204010200). As a PSD source, the

emissions units at this facility were included in the model.

All sources within the Significant Impact Areas (SIA) with potential allowable emissions rates

greater than the PSD significant emission rates (40 tpy NOx, 10 tpy PM2.5) must also be included.

All sources that could potentially interact with the facility were included based on the ‘20D’

approach. Under this approach, the excluded sources are those whose potential allowable

emissions in tpy are less than 20 times the distance between the closest of the modeled units at

Petmin, in kilometers. Any source located greater than 25 km from Petmin were automatically

excluded from the model per The Guideline on Air Quality Models (Appendix W of 40 CFR 51).

Sources modeled are shown in Table 25.

5.8 Modeling Results – PSD Increment

Next, modeling was performed to determine what fraction of the PSD increment the new emissions

units consume. The baseline concentration is defined for each pollutant (and relevant averaging

time) and it is the ambient concentration existing at the time of the trigger date (October 1, 2008

for NO2). Significant deterioration is said to occur when the amount of new pollution would

exceed the applicable PSD increment. This analysis is also necessary to verify that the new Petmin

facility and all of the PSD projects in a 50 km area around the facility do not consume the entire

increment (or more than the increment). The PSD increments for Class II Areas are shown in

Table 31. Ohio EPA has a policy that a new source cannot consume more than one-half of the

available PSD increment. There is no increment for the 1-hour NO2, 1-hour CO, or 8-hour CO

standards. The 24-hour PM2.5 and PM10 increments are the high-second-high values and the annual

increments are the maximum values over five years.

In addition to the Petmin facility, there is only one other facility which triggered PSD in the area,

the Cristal Complex Plant 1 with their final PSD permit issued on October 1, 2008. Therefore,

these are the only sources modeled against the PSD increment. Available increment varies in time

and space. The predicted maximum annual impact at the single highest-case receptor from the

combination of the Project and the existing PSD sources (in this case one facility) is shown in the

following table. Given the minimal impact relative to the increment, it was not necessary to

evaluate what specific fraction of available increment is consumed by the Project at this or any

other receptors.

5.9 Ozone Analysis

On April 30, 2019, U.S. EPA issued guidance on the development of Modeled Emission Rates for

Precursors (MERPs) as a Tier 1 demonstration tool for ozone and fine particulate matter (PM2.5)

under PSD.27 This guidance addresses the MERPs and how to use them to demonstrate that the

Project will not result in quantifiable ozone formation.

Report – Petmin USA Incorporated

September 2018 (Updated December 2019)

- 108 -

Under this guidance, the Petmin proposed NOx emissions increase of 484.57 tons per year is above

the lowest 8-hr ozone MERP value of 126 tons per year of any source modeled in the Ohio Valley

Climate Zone (see Table 4-1 of the MERPs guidance). Proposed VOC emissions are less than the

PSD Significant Emission Rate of 40 tons per year and, therefore, do not require evaluation. Since

the NOx emissions are above the MERP, ozone impacts would be expected to exceed the critical

ozone air quality threshold of 1 ppb. Therefore, further analysis is required.

Since the NOx emissions are above the lowest (most conservative) NOx MERP for 8-hour ozone

in the Ohio Valley Climate Zone of the US, Appendix A of the guidance was used to identify a

comparable hypothetical source that is considered most representative of this source.

The selection of the hypothetical site used for this analysis was straightforward. First, the two

nearest sites, Tuscarawas County, OH (Source 12 in Appendix A of the guidance) and Macomb,

MI (Source 11) are essentially identical in distance from the Project (180 and 186 km,

respectively).

A glance at regional topography and the wind roses for the sites indicate that both terrain and wind

pattern (speeds and directions) are extremely similar between the Macomb, MI site and the Project

site in Ashtabula, OH. The Macomb site is characteristic of the Great Lakes region in key

parameters that influence pollutant travel and ozone formation – wind speed, wind direction,

terrain and general climatology. In contrast, the Tuscarawas County site is located in an area of

complex terrain, with a strong wind frequency from the Southeast and dissimilar speed

distribution, presumably from river valley influences. Figure 11 shows a wind rose plot28 of

meteorological data from a site in Ashtabula County. Figure 12 shows a wind rose plot of

meteorological data from a site in Tuscarawas County, and Figure 13 shows a wind rose plot of

meteorological data from a site in Macomb County.

Figure 13: Wind Rose Plot of Met Data in Macomb County

The Macomb site was selected as the most representative for this analysis in evaluating predicted

ozone formation as a function of NO2 emission rate.

With the elevated emissions releases shown in Appendix A of the guidance, the source derived

NOx MERPs for the 8-hour ozone standard are calculated for source 11 using the equation from

Section 5 of the MERP guidance. These values range from 532 to 875 tons per year as shown in

the calculations below.

• MERP for Source 11 EUS Region Short Release (tpy) = 1.0 ppb x (500 tpy/0.941 ppb) = 531 tpy

• MERP for Source 11 EUS Region Elevated Release (tpy) = 1.0 ppb x (500 tpy/0.936 ppb) = 534 tpy

• MERP for Source 11 EUS Region Elevated Release (tpy) = 1.0 ppb x (1000 tpy/1.703 ppb) = 587 tpy

• MERP for Source 11 EUS Region Elevated Release (tpy) = 1.0 ppb x (3000 tpy/3.426 ppb) = 876 tpy

Because the lowest calculated MERPs shown above is larger than the proposed Project NOx

emission increase, the ozone air quality impacts from the Projects would be expected to be less

than the critical air quality threshold. No further analysis is required based on this screening

procedure.

5.10 Secondary PM2.5 Analysis

The same guidance from April 2019 that was used for the ozone analysis was used for the PM2.5

analysis. Direct PM2.5 emissions were modeled using AERMOD. Both the NOx and SO2

emissions are well below the lowest (most conservative) daily and annual PM2.5 MERP values of

any source modeled in the Ohio Valley or Upper Midwest Climate Zones in the continental US.

However, the NOx and SO2 precursor contributions along with direct PM2.5 contributions are

considered together to determine if the project source’s air quality impact of PM2.5 would exceed

the critical air quality threshold. Because the modeling results for direct PM2.5 emissions were

above the PM2.5 SIL, the secondary analysis for comparison with the SIL is not needed. Scenario

B in Section 4.1.3 of the guidance was followed for a cumulative impact analysis for PM2.5

NAAQS. In this case, the analysis for the secondary formation of PM2.5 from NOx and SO2 are

added to the direct-modeled PM2.5 emissions, including the relevant surrounding sources and also

the background. The calculated total concentration is then compared with the NAAQS for

compliance demonstration purposes. The equations used for the analysis of the primary and

secondary impacts of daily and annual PM2.5 along with the calculations are shown below.

As shown above, the primary and secondary PM2.5 impacts for both the 24-hour and annual

averaging periods are each less than their respective NAAQS as shown above. These results

indicate that the critical air quality threshold would not be exceeded when considering the

combined impacts of these primary and secondary precursors on both daily and annual PM2.5. No

additional modeling is required beyond this screening-level procedure.

5.11 Summary

AERMOD predicts that the construction of the new Petmin facility results in offsite impacts that

exceed the NO2 (1-hour and annual), PM2.5 (24-hour and annual), and PM10 (24-hour) significant

impact levels (SIL). Therefore, a full impacts analysis was conducted to evaluate the maximum

ambient impacts from those pollutants for comparison to the NAAQS. The results of this full

impacts analysis indicate that the construction of the new Petmin facility and other interactive

sources result in maximum offsite impacts below the NAAQS for the modeled pollutants.

The results also indicate that less than one-half of the available PSD increment is consumed from

the Petmin facility and the only other PSD source (Cristal Complex Plant 1) in the area. The offsite

impacts are below the SILs for the PM10 annual averaging period and CO for both the 1-hour and

8-hour averaging periods; therefore, no further analysis was required for PM10 annual or CO. Since

NOx and SO2 emissions create secondary PM2.5, an analysis was performed following U.S. EPA

guidance. This analysis indicates that the critical air quality threshold would not be exceeded when

considering the combined impacts of these primary and secondary precursors on both daily and

annual PM2.5.

Electronic files associated with this study have been transmitted to Ohio EPA Division of Air

Pollution Control (DAPC). The list of files is included in Appendix 3.

6.0 ADDITIONAL IMPACTS ANALYSIS

All PSD applications must include an additional impacts analysis that assesses the impact of air,

ground, and water pollution on soils, vegetation, and visibility caused by the proposed emission

increases and associated growth. The additional impacts analysis generally has four parts:

• growth;

• ambient air quality impact analysis;

• soils and vegetation impacts; and

• visibility impairment.

The additional impacts analysis is performed consistent with the requirements of OAC §3745-31-

17 (Attainment Provisions – Additional Impacts Analysis). The only pollutants for which the

project will exceed the PSD significant emission rates are NOx, CO, and Greenhouse Gases

(GHG). Per the U.S. EPA’s guidance, the additional impacts analyses requirements do not apply

to the emissions of GHGs for a project.29 Therefore, only the impacts of NOx and CO emissions

are addressed in this analysis. The following sections address these four aspects to the project and

demonstrate “no additional impacts.”

6.1 Growth Impact Analysis

The purpose of the growth analysis is to quantify the associated industrial, commercial, and

residential growth that will occur as a result of the project, and to evaluate secondary emissions

that will occur from that projected growth.

The growth analysis addresses only permanent economic growth attributable to the proposed

project. Short-term or temporary impacts, such as construction, are not considered permanent

growth and, therefore, are not addressed as additional impacts.

The proposed project is expected to result in approximately 110 new permanent, full-time positions

at the site. The Pinney Dock site has been previously developed for industrial and commercial use,

with supporting transportation infrastructure (water, rail and roadway). Petmin anticipates that the

workforce will be drawn largely from the surrounding communities. As a result of the relatively

self-contained nature of Petmin’s manufacturing operations, no related industrial growth is

expected to accompany the operation of the plant. In summary, secondary emissions associated

with the incremental growth as a result of this project will be insignificant.

6.2 Ambient Air Quality Analysis

The ambient air quality analysis projects the air quality which will exist in the area of the proposed

source or modification from the growth analysis after it begins operation. No sources of secondary

air emissions were identified that could warrant adding to the ambient air quality analysis

presented in modeling section of this study.

6.3 Soils and Vegetation Analysis

Gaseous emissions of air pollutants can lead to deterioration of soil quality and subsequently

impact vegetation. For most types of soils and vegetation, ambient concentrations of criteria

pollutants below the secondary national ambient air quality standards (NAAQS) will not result in

harmful effects.

Modeled NO2 concentrations from the proposed project are well below the well below the NAAQS

for NO2 (100 g/m3 as an annual average).

As shown in the modeling section, the predicted annual average NO2 concentration at the worst-

case receptor is 5.10 μg/m3 (2.83 x 10-3 ppmv NO2), including background.

A study from EPA Region 7 concluded:

In periods of two weeks or greater duration with intermittent exposures of several hours

per day, adverse effects on growth and yield start to appear when the concentration of NOx

reaches the range of 0.1 to 0.5 ppm, depending on the species of plant, nature of effect, and

conditions of exposure.30

The predicted concentration is approximately two orders of magnitude below the range at which

adverse effects have been observed for NOx-sensitive plants. Therefore, no impact on soils and

vegetation is predicted.

In the case of CO, no secondary NAAQS has been established. There is no known impact on soils

and vegetation associated with CO emissions that meet the primary NAAQS.

6.4 Visibility

A Level I visibility analysis for the proposed project emissions was conducted using the U.S. EPA

VISCREEN model. Maximum annual emission rates of NOx and particulate were input. Typically,

the distances used in this model are the nearest and furthest Class I Areas. In this case, there are

no Class I areas within 300 km. According to the model, “although VISCREEN is designed

primarily for assessing plume visual impacts in Class I areas, it can also be applied in PSD Class

Page 170: PTI/PTIO Application A0066143 Petmin USA Incorporated ... · 1. 2. 3.--Petmin USA Incorporated - 0204012023 Page 1 PTI/PTIO Application - A0066143 Division of Air Pollution Control

II areas. In such cases these distances can be specified arbitrarily.”31 For this analysis, per the

protocol response from Ohio EPA32, the distances to the State Game Lands #314 in Erie County,

PA, (24 km and 27 km for the minimum and maximum distances, respectively), were used. The

results, presented in Appendix 4, indicate that the project impacts will not exceed the visibility

screening criteria. Therefore, a refined analysis of visibility impacts is not warranted.

Furthermore, there are no scenic vistas, airports, or other areas near the site that would be affected

by trace reductions in visibility.

6.5 Class I Area Impacts Analysis

There are no Class I areas located within 300 km of the proposed project. Based on the Federal

Land Manager (FLM) guidance:

Therefore, the Agencies will consider a source locating greater than 50 km from a Class I area

to have negligible impacts with respect to Class I AQRVs if its total SO2, NOx, PM10, and

H2SO4 annual emissions (in tons per year, based on 24-hour maximum allowable emissions),

divided by the distance (in km) from the Class I area (Q/D) is 10 or less. The Agencies would

not request any further Class I AQRV impact analyses from such sources.33

The nearest Class I area is Otter Creek Wilderness, which is 348 km from Petmin. The Q/D for

the project is approximately 1.5, well below the FLM’s guidance threshold of 10. Therefore, no

further AQRV analysis is required for the Project.

PM10 emissions are based on the minimum, guaranteed absolute efficiency of the baghouse, and the gas flow rate.

The maximum fraction of PM2.5 was provided by the EAF design engineer team.

Calculations, except for PM2.5 (see footnote), are based on AP-42 emission factors for minimills, which typically have less

consistent and controlled inputs. These factors are expected to be conservative. AP-42 emission factors for sulfur, lead and

specific organic compounds were not used because they are not expected to be present in process inputs.

A complete cycle of the EAF processes 153 tons of DRI and flux over ~132 minutes, consisting of ~112 minutes of smelting

and ~20 minutes for tapping to the ladle, yielding ~132.3 tons of metal and ~20.7 tons of slag.

The fumes generated during the smelting are extracted from the roof of the furnace via a flexible suction pipe cooled with

water leading to a sedimentation chamber ( “drop-out box”). The configuration of the sedimentation chamber makes it

possible to separate coarse particles from the gas and the addition of air to the hot gas (800 °C) combusts most of CO.

The final emission factor was provided by the EAF design engineers.

Iron ore pellets are stored and loaded to Petmin's conveying system by Kinder Morgan. Pellets are

screened to remove undersized material. Other materials, i.e., slag and ingots are solidified metal from the

EAF and are not included here because they are not expected to contain fines.

Emission factors for PM2.5 from screening and transfer points are shown in AP-42 Section 11.19.2 as "ND",

or "No Data". The controlled emission factors for the same processes show values for both PM10 and

PM2.5. The ratio of the controlled emission factors for the two pollutants was applied to the uncontrolled

PM10 emission factor to calculate a PM2.5 emission factor.

Indoor transfer points and the screening operation are in buildings which are kept under negative pressure

by the applicable baghouses. Capture efficiency is presumed to be 100%. Baghouse control efficiency is

used to calculate these emissions

Iron ore pellets are received, stored, and loaded into Petmin's pellet handling system by Kinder-Morgan (K-M). Petmin has no pellet storage piles. Iron

ingots are stored by Petmin briefly before transfer to K-M or a third party. Remet is stored in two separate piles onsite. These temporary storage piles

are addressed below.

Remet consists of partially-reduced iron pellets. Moisture content is set at 1.5%, based on company information. Fines are estimated by the equipment

manufacturer at 0.5%. Remet is only produced during shutdown of the process and Petmin estimates that the maximum throughput is 8,000 metric tons

per year.

The pig iron from the process is cast into small ingots and placed in a stockpile prior to loading on trucks. The ingots handling of is not included in these

calculations because they have negligible fines and handling is not expected to result in negligible emissions.

These calculations predict emission rates below the de minimis threshold (OAC rule 3745-15-05) from all storage piles combined. Therefore, these units are listed in

the application as "de minimis."
