SECTION I. INTRODUCTION

American Castings, LLC (AMC or applicant) submitted an application received on October 27,

2014 to renew their Title V permit. American Castings is a steel foundry that manufactures

ductile iron and gray iron castings (SIC 3321). The facility is a major source of criteria

pollutants emitting at PSD (Prevention of Significant Deterioration) levels. It is also a major

source of hazardous air pollutants (HAPs).

AMC requested changes to their existing permit, Permit No. 2006-166-TVR (M-2). The list of

changes was revised as a result of discussion with AMC and their reviews of the working

document for this renewal TV Permit, No. 2014-2107-TVR2. The revised list of changes is

itemized below. These changes were deemed to be a significant modification and are being

tracked as a separate permit application, Permit No. 2006-166-TVR (M-3) but have been

included in this Title V renewal permit.

Remove limit of nine (9) molds per hour on M-9 and replace with limit on sand usage in

tons per hour and tons per day. Based on the calculation methodology for emissions from

pouring, cooling and shakeout, the number of molds for M-9 is irrelevant to the

calculation. Thus eliminating the limit on number of molds will not result in any changes

to emissions.

Combine and reorder various emissions points within the EUGs in order to better group

the like-kind equipment in each EUG. This change was made as a convenience in the

way the facility accounts for emissions and did not involve changing any individual

limits or combining limits into a cap limit.

Recombine EUG M – Pouring and Cooling with EUG N – Shakeout to be one EUG as in

the original Title V permit, to be called EUG M - Molding, Pouring, Cooling and

Shakeout and reestablish the associate text concerning derivation of emissions limits.

This change is to return to the original grouping as presented in the original Title V

permit and did not result in any changes to emissions limits.

Correct the emissions limits for Emissions Points S-1, S-2 through S-5 and S-6 to reflect

what has been permitted since the original permit and also to retain the additional limit of

1.5 TPY-PM10 established for S-7, a new shot blast unit permitted under by Permit No.

2006-166-TVR (M-1). This was a correction to re-incorporate what was permitted under

Permit No. 2006-166-TVR (M-1). The justification for this project and PSD analysis

were presented in the application for that permit as well as in that permit.

Revise specific conditions to not reference emissions sources that have been historically

removed. No limits were changed or affected by this revision.

Include changes approved in Permit No. 2006-166-TVR (M-2). This is only to

incorporate what was permitted under Permit No. 2006-166-TVR (M-2). The

justification for this project and PSD analysis were presented in the application for that

permit as well as in that permit.

Revise CAM Plan for the M-8 Carrier Barrelhorse to reflect a baghouse control instead of

a wet scrubber. The baghouse was installed with notification from AMC. This is

allowed under Specific Condition No. 6 of the current operating permit, which states

“Alternative control equipment may be used provided the control efficiency is equivalent

or higher than those listed.” The baghouse has a higher control efficiency than the

scrubber and therefore results in a slight reduction of emissions.

SECTION II. FACILITY DESCRIPTION

The facility currently includes three 23-ton coreless induction furnaces for melting ductile iron.

The facility-wide pouring rate is limited to 26 tons per hour and 187,200 tons per year from the

previous permit and the limits are PSD (Prevention of Significant Deterioration) limits.

Operating all three furnaces simultaneously provides for a maximum melting rate of 26 TPH

allowing for slagging and charging. Also included are facilities for receiving, forming,

recovering, and disposing of sand used to make molds for the melted metals. A painting

operation places weatherproofing coating on some products. A detailed description of each area

in the foundry follows.

Scrap Handling/Preheating/Metal Melting/Refining

Low-manganese steel, foundry returns, and pig iron are loaded into storage bins from railroad

cars and other sources. Approximately 25 percent of this operation occurs outdoors and 75

percent occurs inside the foundry building. A typical charge weighs approximately 10 tons and

consists of 53 percent foundry returns, 5 percent pig iron, and 42 percent low manganese steel.

Page 3: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 3

The charge composition can change with material price consideration and/or availability. The

charge is weighed in scaled hoppers and transferred to a preheat conveyor. The Venetta Furnace,

a natural gas fired preheater with a maximum heat input of 23.52 MMBTU/hr, heats the scrap to

approximately 800 degrees Fahrenheit to remove oil and moisture from the scrap. The preheat

charge is then loaded into a charge bucket which is lifted by crane, and the charge is put into a

melt furnace.

Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The

melting operations are divided between the melt furnaces and the holding furnaces. The melt

furnaces melt solid metals into a molten stage so that alloys may be added. The composition of

the charge depends upon the specific metal characteristics required. Addition of alloys is done to

improve properties of the castings. Alloying generally consists of 500 to 600 pounds of graphite,

50 pounds of silicon carbide, 15 to 20 pounds of ferrosilicon, and 10-15 pounds of

ferromanganese. Molten metal is tapped by tilting the furnace and pouring through a spout to

one of three, 42-ton or one 45-ton holding furnaces. The holding furnaces maintain the

temperature of the melt at the desired pouring temperature of 2,750oF. Slag removal is done as

part of normal operations of both the melt furnaces and the holding furnaces. Slag removal

reduces the amount of melted metal that reaches the rest of the sources in the foundry by 6%.

However, to be conservative emissions are based on 26 tons/hour.

When a holding furnace is full and the charge attains the desired temperature the metal is tapped

into a ladle containing magnesium ferrosilicon. The introduction of magnesium into the iron

improves its crystalline properties and facilitates the transition from gray to ductile iron. Ductile

iron is formed as a steel matrix containing spheroidal particles (or nodules) of graphite. Ordinary

cast iron contains flakes of graphite. Each flake acts as a crack, which makes cast iron brittle.

Ductile irons have high tensile strength and are silvery in appearance. The metal is then

transferred to pouring ladles and ferrosilicon is added for further refining. Such refining further

improves the properties of the ductile iron. Both the transfer and pouring ladles are heated by

natural gas-fired heaters.

Mold Making

Green Sand Mold Making

The green sand molding process is used to make forms used to shape the exterior of the castings.

The green sand molding process uses sand from the green sand shake-out. Sand separated by

shake-out is passed through the rotary screens and a sand cooler before it is recycled to the core

or mold lines.

The Simpson Multi-cooler Sand Cooler was authorized by Permit No. 97-125-TV (M-2) for the

Line 6 Green Sand Molding line. The sand cooler is used to condition the sand prior to reuse.

The sand cooler system is installed in-line with the existing sand mold handling system, at a

point after mold shake-out has occurred. From shakeout, hot sand travels down a conveyor belt

underneath a cross-belt magnetic separator, dumps onto another conveyor belt, which is covered,

where the sand is then transported outside the main building to a sand tower which houses the

sand cooler. Inside the sand tower, the sand drops into a bucket elevator and is conveyed

upwards to a rotary screen. The sand passes through the rotary screen to a storage silo. Sand

exits the storage silo via a vibratory feeder and enters into the sand cooler. The sand cooler is an

Page 4: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 4

enclosed tank with paddles to lift and drop the sand to allow cooling by heat transfer to the air,

which is being drawn through the cooler by a fan. Air discharging from the sand cooler is

directed into a baghouse, along with other pick-up air points within the sand tower. Particulate

fines collected in the baghouse are returned to the process stream by a new conveyor, installed to

eliminate the trucking and disposal of this material. Cooled sand exits the cooler onto another

conveyor belt which transports the sand back into the sand handling system inside the main

building and dumps the sand onto another conveyor belt. This transfer point is covered, under

vacuum, and pulls any particulate to a baghouse. The emissions associated with such are

minimal.

Reclaimed sand, new silica sand, bentonite clay, sea coal, and water are used to make forms used

to shape the exterior of the castings. Additional conditioning occurs in sand mullers and mixers

which prepare the sand and binders for the cores and molds. Bentonite clay and water are used

as the binding agents. Particulate matter emissions from the rotary screens, sand mullers, and

shake-out are controlled by baghouse at 99% efficiency. After mixing, the sand mixture is

transferred to the molding machines, where it is simultaneously packed mechanically over the

top and bottom portions of the pattern. Once the sand mixture has been properly molded, the

patterns are withdrawn from the forms, using a release agent to facilitate release. Removal of the

pattern leaves a cavity inside the mold that forms the outside of the casting. Cores (described

below) are then set to produce the internal voids in the castings. After the finished mold

(exterior form and core) is prepared, a conveyor transports the mold to pouring where molten

metal from the melt shop is poured into molds.

PUNB Mold Making

Phenolic urethane no-bake (PUNB) molding utilizes a three-part, phenolic urethane binding

system where chemical reactions take place at ambient temperatures. The first part of the PUNB

process uses a phenolic resin, the second part contains an isocyanate component, and part three is

a liquid catalyst. PUNB parts 1, 2, and 3 are mixed with silica sand in a mixer. Silica sand

consists of reclaimed sand from the shake-out process and fresh silica from the sand bin. From

the sand bin, the sand is sent through a preheater and into the mixer. A typical charge consists of

80 percent reclaimed sand and 20 percent fresh silica sand. Resins (PUNB parts 1 and 2), PUNB

catalyst, and iron oxide are also added to the mixer. After mixing, the sand mixture is conveyed

to the mold line where the molds are formed manually. The cope (top half) is assembled first,

followed by the drag (bottom). After assembly, the molds are rotated to allow separation from

the pattern using a release agent. Some of the molds are then washed with a water-based

graphite refractory slurry, cured, and dried with an electric infrared heater. After drying, cores

from the core room are set into place, and the cope is rotated and set in place on top of the drag.

A weight is then added to the mold to prevent cope lift due to metal pressure during pouring.

The weighted molds are then routed to the pouring lines for casting.

Core Making Operations

Cores are molded sand shapes used to make the internal voids in castings. The Core Room uses

three different processes to make cores: a) shell, b) phenolic urethane cold box (PUCB), and c)

phenolic urethane no-bake (PUNB). Sand is recycled from the mold lines shakeouts and reused

in the core room in the PUCB and PUNB processes. Part of the cores from the PUCB and the

Page 5: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 5

PUNB core processes are given a protective wash. This is accomplished by dipping the cores

into a graphite refractory water-based slurry. The washed cores are then dried in two natural

gas-fired drying ovens. Core mud may be used to repair damaged portions of a core. The cores

from all three processes, each described following, are transferred to molding lines for insertion

into the mold.

Phenolic Urethane Cold Box (PUCB) Process

The PUCB process utilizes a phenolic cold box binding system. With this system, sand is mixed

with the three different parts of the organic binder chemicals. The first part is the phenolic resin,

the second part is an isocyanate, and the third is the catalyst (gaseous dimethylethylamine or

DMEA). The sand is mixed with the phenolic and isocyanate resins in a mixer. There are eleven

core machines. The mixed sand with resin is then put into core boxes which are gassed with the

catalyst, causing the resin to bind to the sand and to make the core. DMEA emissions are

controlled by an acid/caustic scrubber with a 95% control efficiency which uses caustic soda and

sulfuric acid to neutralize the DMEA emissions. A release agent is applied to the core boxes to

allow removal of the core from the core box after the core is made. Some of the cores are then

sent to the core wash process. Core mud is utilized, as needed, to finish out the cores. The cores

are then baked by a 2.5 MMBTUH natural gas fired oven and then sent to the mold lines for

insertion. Particulate matter emissions from the mixers and the sand storage are captured by a

99% efficient baghouse. The current chemical binders are stored in two 6,000 gallon bulk

storage tanks.

Phenolic Urethane No-Bake (PUNB) Process

The PUNB process is a three-part, phenolic urethane no-bake binding system where chemical

reactions take place at ambient temperatures. The first part of the PUNB process uses a phenolic

resin, the second part contains an isocyanate component, and part three is a liquid catalyst.

PUNB parts 1, 2, and 3 are mixed with silica sand in a mixer. After mixing, the sand is sent to

the core box to be molded into the proper core shapes. A release agent is used to facilitate

removal of the finished cores. Some of the cores are then sent to the core wash process. Core

mud is applied as needed to finish the cores. The cores are then dried by a 2.5 MMBTUH

natural gas oven and sent to the mold lines for insertion. Under EUG C - Core and Mold

Operations, the facility currently operates one PUNB core sand mixer, designated as C-20. The

new mixer is designated as CB-20. Particulate matter emissions from the new mixer will be

controlled by the same baghouse serving the existing equipment, having 95% efficiency.

Chemical binders used in this process are stored in two 6,000 gallon bulk storage tanks.

Shell Process

The old shell core machines, C-1 through C-6, have been removed from the site and machines C-

26 and C-27 were added by Permit No. 97-125-TV (M-4). The shell process utilizes sand coated

with phenolic resin and hexamethylenetetramine. The sand is charged into the shell machines

and heat is applied from combustion of natural gas. The resin coating is a thermosetting type,

which bonds together when the heat is applied. The pattern or core box temperature usually

varies between 350o and 450

oF. A release agent is used to allow separation of the core from the

pattern. The shell cores are then sent to the mold lines for insertion into the molds.

Pouring, Cooling, and Shakeout

Page 6: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 6

After the molten metal has solidified in the molds, the hot castings are routed through cooling

tunnels. When cooling is finished, the castings are separated from the form/core mold sand via a

shake-out process. Castings are then routed to the finishing and cleaning area. Any remaining

sand is cleaned off the castings by a shot-blast machine in the finishing area. A screening

conveyor reclaims the sand and recycles it through a rotoclaim bin into the sand bin. Particulate

matter emissions from the shake-out and sand handling are controlled by a dry dust collection

system at 98% efficiency.

Finishing

Metal finishing removes sand and unwanted appendages, prepares the castings surface, and

includes a quality assurance step. Castings from the Green Sand lines and the PUNB line are

sent to the finishing area. De-spurring, blasting, and grinding are all performed in this area. De-

spurring removes unwanted appendages such as spurs, gates, and risers by hitting with a sledge

hammer. Remaining sand is cleaned off the castings by a shot-blast machine. The abrasive blast

cleans the castings by removing any remaining mold sand and scale. Additional touch-up

including grinding and surface repair is performed, and castings are then sent for final inspection.

Particulate matter is controlled with a dry collection system at 98% efficiency.

Painting

Some finished castings are painted based on product requirements. The castings undergo rinsing

in a multistage bath consisting of detergent wash, tap water rinse, phosphoric acid rinse, tap

water rinse, and a final deionized water rinse. Two natural gas-fired burners, 2.5 MMBTUH, are

used to warm the soap and first water baths. Thoroughly rinsed castings are sent to a 5,000

gallon water-based, electrodeposition paint dip system. The paint consists of a paste that

provides the color, an epoxy paint resin that provides the medium, and the solvents.

Formaldehyde has been discussed in previous permit memorandums for use as a biocide. The

facility has discontinued the use of formaldehyde. Components and deionized water are pumped

into the tank and mixed. Paint is added from a replenishing tank to maintain a constant level.

The painted castings undergo a post rinsing and are sent to a 4.0 MMBTUH natural gas-fired

oven to cure at 450oF. Following the oven, the castings are cooled by the chiller’s water sprays.

Emergency Engines

The facility has one 760-hp Cummins emergency diesel generator. Emissions are based on 500

operating hours per year. The unit is an insignificant activity.

SECTION IV. EMISSIONS

Emissions of criteria pollutants are directly proportional to the melt rates and the associated raw

material handling. In general, these emissions can be calculated using available throughput-

based emissions factors, in units of lbs/ton-metal poured or lbs/ton-sand used. Individual

throughput rates for most emissions units are listed in the equipment section. Actual throughput

rates may be less, depending on demand. Steel throughput is generally reduced by about 6% past

the melting area due to slagging and charging. Material usages are based on facility

requirements for processing 26 ton/hr of metal melt. Combustion emissions from natural gas-

fueled equipment are based on AP-42 (7/98), Tables 1.4-2 and 1.4-3. The pouring process also

generates combustion-like emissions, for which emissions factors are taken from a variety of

technical sources detailed in later discussion.

The source for the derivation of the original PM emissions factor for sand handling system is

referenced in the memorandum of Permit No. 97-125-TV, page 12 as 3.6 lb/ton sand handled

from AP-42 (10/86), Table 7.10-4 [now Table 12.10-7 (1/95)]. This emission factor was

normalized to units of lbs-PM/ton-metal using a 6.78:1 sand-to-metal ratio. PM10 was then based

10% of PM from “An Inventory of Iron Foundry Emissions,” Modern Castings, 1972.

3.6 lbs-PM/ton-sand x 6.78 sand/metal ratio = 24.41 lbs-PM/ton-metal

PM10 = 24.41 tons/year x 0.10 PM10/PM = 2.41 lbs-PM/ton-metal (2.44 rounded)

Annual Limit = 2.44 lbs-PM10/ton-metal x 151,840 tons metal x 1-ton/2,000-lbs x 0.05

controlled = 9.27 TPY

This annual limit was assigned to A-2 and A-3, the Sand Muller 1, GSML #406 and the Simpson

Multi-cooler MC-200, GSML #406.

VOC Emissions from Core and Mold Operations

The method for calculating emissions of VOCs generated from the mixing and curing of cores

and molds in the Title V permit was a mass balance based on 50% evaporation of the VOC

content of the core binders. Permit No. 97-125-TV (M-3) changed the 50% evaporation factor to

that determined from a test procedure developed and conducted by the Ohio Cast Metals

Page 11: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 11

Association (OCMA) as part of a Memorandum of Understanding between OCMA and the Ohio

Environmental Protection Agency. This test procedure is a simple mass balance method which

involves weighing the pre-mix ingredients, mixing them and then recording incremental weight

loss measurements until cure time has been achieved. The specifics of the method are in the

permit conditions. The tests will be conducted by the vendor(s) of the binder material(s). The

permit also allows for EPA Method 24 or EPA Method 24A.

Limits on material usage rates were eliminated from previous permits because compliance with

the VOC limit now depends on the emission factor specific to the product, which can change

from one product to the next. Emission factors are not specified in this permit because they will

be specific to each product. Therefore material usage can change with changes in the product

emission factor.

Limits on hourly VOC emission rates were removed in Permit No. 97-125-TV (M-5) to

accommodate elimination of certain requirements to comply with OAC 252:100-41, Part 5, that

appeared to no longer be needed. However, these limits were restored in Permit No. 2006-166-

TVR because it is believed that they were utilized in the PSD and Title V permits in the air

dispersion modeling that was used to check compliance with the NAAQS. From permit No. 95-

527-C (PSD), ‘VOC is not limited directly by NAAQS. Rather, it is regulated as an ozone

precursor. EPA developed a method for predicting ozone concentrations based on VOC and

NOX concentrations in an area. The ambient impacts analysis utilized these tables from

"VOC/NOX Point Source Screening Tables" (Richard Scheffe, OAQPS, September, 1988). The

Scheffe tables utilize increases in NOX and VOC emissions to predict increases in ozone

concentrations. Based on this method, incremental ozone impacts for added emissions were

conservatively estimated at 29.95 µg/m3. Therefore, VOC limits, in pounds per hour and tons

per year, were restored from the Title V permit, but as modified in permit No. 97-125-TV (M-1).

Particulate Emissions from Core and Mold Operations

Emissions calculation methods and limits are carried forward from previous permits. The

applicant uses an emissions factor of 1.1 lbs-PM/ton-metal poured from AP-42, Table 12.10-7

for core making and baking, and as noted above from Permit No. 97-125-TV, an assumption that

Page 12: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 12

PM10 and PM2.5 are 10% of PM. An existing baghouse already controlling emissions from the

existing process provides a control efficiency of 95%.

From the memorandum of Permit No. 97-125-TV, emission factors in units of lbs-PM/ton-sand

were normalized to units of lbs-PM/ton-metal using a 6.78:1 sand-to-metal ratio. PM10 was then

based 10% of PM from “An Inventory of Iron Foundry Emissions,” Modern Castings, 1972. The

above emissions factor is already expressed in lbs-PM/ton-metal poured. For C-20B, having a

maximum capacity of 250 TPH sand throughput, this would be 36.87 TPH metal pour except

that AMC has a facility-wide pour limit of 26.0 tons per hour or 187,200 tons per year.

Therefore, emissions associated with melting, holding, and refining primarily include particulate

matter (PM). Calculations for these emissions are carried forward from the Title V

memorandum, with revisions for clarification. PM10 emissions for melting and holding were

calculated using the total PM emission factor from AP-42 (1/95), Table 12.10-3, Electric

Calculations for emissions of particulate matter from material handling and preheating are taken

from the Title V permit memorandum which states: “Associated emissions include PM10 from

material handling, 25% outdoor and 75% indoor, and pre-heating which also results in

combustion gases. Emission factors are based on “An Inventory of Iron Foundry Emissions,”

Modern Castings, 1972. An emission factor for PM30 was given and an engineering estimate that

15% was PM10 from handling and make-up and 45% from charge pre-heating was used. All

sources are uncontrolled.” Based on the factors given in the table shown below, apparently the

75% factor was applied to “Charge Make-up” emissions.

Criteria pollutants are generated as a result of combustion of natural gas fuel in process heaters.

Emissions were calculated using AP-42 1.4-1 for boilers/heaters less than 100 MMBTU/hr and

the total combined heat input rating. Individual equipment items and their heat input ratings are

detailed in the “Equipment” section above. The total combined rating of combustion equipment

is 55.52 MMBTUH. This combined calculation is applicable because all heaters are rated less

than 100 MMBTUH and therefore have the same emissions factors. The results of the

calculation for each pollutant are tabulated below.

Particulate Emissions from Shotblasting and Grinding

PM10 emissions from shotblasting and grinding for Permit No. 2006-166-TVR (M-1) were based

on a total PM emission factor of 17 lb/ton-metal handled from AP-42 (5/03), Table 12.10-7,

“Cleaning, Finishing”, and an assumption that PM10 can be calculated as 10% of PM. This

method replaces the one from the previous permit where emissions from shotblasting were taken

from “An Inventory of Iron Foundry Emissions,” Modern Castings, 1972, and from EPA-600/2-

80-021, U.S. EPA, 1987.

An analysis to demonstrate that a significant increase has not occurred from the new blast unit

was presented by the applicant, based on the potential to emit. Using an uncontrolled PM

emissions factor (from AP-42, Table 12-10.7) of 17 lbs-PM/ton of iron and a control efficiency

of 98% results in controlled emissions of 15 TPY. Assuming 10% is PM10 and PM2.5 resulted in

1.5 TPY PM10 and 1.5 TPY PM2.5. The applicant also stated that the new blast unit will not

create any associated emissions or debottlenecking from other processes.

Additionally, the new shot blast unit will not increase the amount of total particulate matter

generated from finishing operations. Therefore, total PM emissions are not increased from

current operations and are represented in the table below as in previous permit memorandums.

SECTION VI. OKLAHOMA AIR POLLUTION CONTROL RULES

OAC 252:100-1 (General Provisions) [Applicable]

Subchapter 1 includes definitions but there are no regulatory requirements.

OAC 252:100-2 (Incorporation by Reference) [Applicable]

This subchapter incorporates by reference applicable provisions of Title 40 of the Code of

Federal Regulations listed in OAC 252:100, Appendix Q. These requirements are addressed in

the “Federal Regulations” section. NESHAP EEEEE is applicable to this facility.

OAC 252:100-3 (Air Quality Standards and Increments) [Applicable]

Subchapter 3 enumerates the primary and secondary ambient air quality standards and the

significant deterioration increments. At this time, all of Oklahoma is in “attainment” of these

standards. In addition, modeled emissions from the proposed facility, conducted for PSD and Title

V permitting, demonstrated that the facility would not have a significant impact on air quality.

OAC 252:100-5 (Registration, Emissions Inventory and Annual Operating Fees) [Applicable]

Subchapter 5 requires sources of air contaminants to register with Air Quality, file emission

inventories annually, and pay annual operating fees based upon total annual emissions of regulated

pollutants. Emission inventories were submitted and fees paid for previous years as required.

OAC 252:100-8 (Permits for Part 70 Sources) [Applicable]

Part 5 includes the general administrative requirements for Part 70 permits. Any planned

changes in the operation of the facility that result in emissions not authorized in the permit and

that exceed the “Insignificant Activities” or “Trivial Activities” thresholds require prior

notification to AQD and may require a permit modification. Insignificant activities refer to those

individual emission units either listed in Appendix I or whose actual calendar year emissions do

not exceed the following limits.

5 TPY of any one criteria pollutant

2 TPY of any one hazardous air pollutant (HAP) or 5 TPY of multiple HAP or 20%

of any threshold less than 10 TPY for a HAP that the EPA may establish by rule

Emission limitations and operational requirements necessary to assure compliance with all

applicable requirements for all sources are taken from the permit application, or are developed

from the applicable requirement.

OAC 252:100-9 (Excess Emissions Reporting Requirements) [Applicable]

Except as provided in OAC 252:100-9-7(a)(1), the owner or operator of a source of excess

emissions shall notify the Director as soon as possible, but no later than 4:30 p.m. the following

working day of the first occurrence of excess emissions in each excess emissions event. No later

than thirty (30) calendar days after the start of any excess emission event, the owner or operator

of an air contaminant source from which excess emissions have occurred shall submit a report

for each excess event describing the extent of the event and the actions taken by the owner or

operator in response to this event. Request for mitigation, as described in OAC 252:100-9-8,

shall be included in the excess emissions event report. Additional reporting may be required in

Page 25: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 25

the case of ongoing emission events and in the case of excess emissions reporting required by 40

CFR Parts 60, 61, or 63.

OAC 252:100-13 (Open Burning) [Applicable]

Open burning of refuse and other combustible material is prohibited except as authorized in the

specific examples and under the conditions listed in this subchapter.

OAC 252:100-19 (Particulate Matter (PM)) [Applicable]

Section 19-4 regulates emissions of PM from the combustion of fuel in any new and existing fuel-

burning unit, with emission limits based on maximum design heat input rating. Fuel-burning unit

is defined in OAC 252:100-19 as any internal combustion engine or gas turbine, or other

combustion device used to convert the combustion of fuel into usable energy. Thus, the gas-fired

equipment listed in the following EUG tables is subject to the requirements of this subchapter.

Appendix C specifies a PM emission limitation of 0.60 lb/MMBTU for all equipment at this

facility with a heat input rating of 10 MMBTUH or less, and a limit of 0.49 lb/MMBTU for the

23.52 MMBTUH Venetta Furnace.

The permit will require some of the listed operations to use dry controls. These controls will be

monitored for compliance with this subchapter.

OAC 252:100-25 (Visible Emissions and Particulates) [Applicable]

No discharge of greater than 20% opacity is allowed except for short-term occurrences that consist

of not more than one six-minute period in any consecutive 60 minutes, not to exceed three such

periods in any consecutive 24 hours. In no case shall the average of any six-minute period exceed

60% opacity. Monitoring of pollution control equipment is a requirement of the permit to assure

compliance with this standard.

OAC 252:100-29 (Fugitive Dust) [Applicable]

No person shall cause or permit the discharge of any visible fugitive dust emissions beyond the

property line on which the emissions originated in such a manner as to damage or to interfere with

the use of adjacent properties, or cause air quality standards to be exceeded, or to interfere with the

maintenance of air quality standards. Fugitive sources are contained within the facility, therefore,

fugitive emissions will not interfere with the use of adjacent properties.

OAC 252:100-31 (Sulfur Compounds) [Part 5 Applicable]

Part 5 limits sulfur dioxide emissions from new fuel-burning equipment (constructed after July 1,

1972). For gaseous fuels the limit is 0.2 lb/MMBTU heat input averaged over 3 hours. The

permit requires the use of pipeline natural gas as defined in Part 72 having 0.5 grains TRS/100

scf to ensure compliance with Subchapter 31.

OAC 252:100-33 (Nitrogen Oxides) [Not Applicable]

This subchapter limits new gas-fired fuel-burning equipment with rated heat input greater than or

equal to 50 MMBTUH to emissions of 0.20 lbs of NOX per MMBTU, three-hour average. There

are no equipment items that exceed the 50 MMBTUH threshold. The largest of the units is the

Venetta Furnace, rated at 23.5 MMBTUH, which is less than the 50 MMBTUH applicability

threshold.

OAC 252:100-35 (Carbon Monoxide) [Not Applicable]

This subchapter affects gray iron cupolas, blast furnaces, basic oxygen furnaces, petroleum

catalytic cracking units, and petroleum catalytic reforming units. It requires removal of 93% or

more of CO by “complete secondary combustion” from new sources and also from existing

sources located in or significantly impacting a non-attainment area for CO. “Gray iron cupola”

means shaft-type furnace used for the melting of metals usually consisting of, but not limited to,

Page 27: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 27

the furnace proper, tuyeres, fans or blowers, tapping spout, charging equipment, gas-cleaning

devices and other auxiliaries. Shaft furnaces used for processing non-metallic materials are not

included under this definition but are included in the definition of process equipment. This

facility, among other processes, manufactures gray iron castings but has no gray iron cupolas or

any other of the listed processes subject to this rule. There are no affected sources.

OAC 252:100-37 (Volatile Organic Compounds) [Part 5 and Part 7 Applicable]

Part 3 requires storage tanks with a capacity of 400 gallons or more and storing a VOC with a

vapor pressure greater than 1.5 psia to be equipped with a permanent submerged fill pipe or with

an organic vapor recovery system. The only fuel tank on-site stores diesel having a vapor

pressure less than 1.5 psia and has a capacity less than 400 gallons.

Part 5 limits the VOC content of coatings used in coating lines and operations. Based on mixture

requirements the coating will have a maximum content of 3.52 lbs/gallon. This content accounts

for all solvent and is in compliance with the 4.8 lb/gal limit for maintenance finishes.

Part 7 requires fuel-burning equipment to be operated and maintained so as to minimize VOC

emissions. Temperature and available air must be sufficient to provide essentially complete

combustion. The combustion equipment, as listed above in the applicability section for

Subchapter 19, is designed to provide essentially complete combustion of organic materials.

OAC 252:100-42 (Toxic Air Contaminants (TAC)) [Applicable]

This subchapter regulates toxic air contaminants (TAC) that are emitted into the ambient air in

areas of concern (AOC). Any work practice, material substitution, or control equipment required

by the Department prior to June 11, 2004, to control a TAC, shall be retained, unless a

modification is approved by the Director. Since no AOC has been designated there are no

specific requirements for this facility at this time.

OAC 252:100-43 (Testing, Monitoring, and Recordkeeping) [Applicable]

This subchapter provides general requirements for testing, monitoring and recordkeeping and

applies to any testing, monitoring or recordkeeping activity conducted at any stationary source.

To determine compliance with emissions limitations or standards, the Air Quality Director may

require the owner or operator of any source in the state of Oklahoma to install, maintain and

operate monitoring equipment or to conduct tests, including stack tests, of the air contaminant

source. All required testing must be conducted by methods approved by the Air Quality Director

and under the direction of qualified personnel. A notice-of-intent to test and a testing protocol

shall be submitted to Air Quality at least 30 days prior to any EPA Reference Method stack tests.

Emissions and other data required to demonstrate compliance with any federal or state emission

limit or standard, or any requirement set forth in a valid permit shall be recorded, maintained,

and submitted as required by this subchapter, an applicable rule, or permit requirement. Data

from any required testing or monitoring not conducted in accordance with the provisions of this

subchapter shall be considered invalid. Nothing shall preclude the use, including the exclusive

use, of any credible evidence or information relevant to whether a source would have been in

compliance with applicable requirements if the appropriate performance or compliance test or

procedure had been performed.

subject to this subpart. §60.4205 specifies the standards for owners and operators of emergency

stationary CI internal combustion engines.

The 760-horsepower Cummins emergency engine was manufactured and constructed prior to the

threshold dates and is therefore not affected under this subpart.

None of the listed subparts affect induction furnaces.

NESHAP, 40 CFR Part 61 [Not Applicable]

There are no emissions of any of the regulated pollutants: arsenic, asbestos, benzene, beryllium,

coke oven emissions, mercury, radionuclides, or vinyl chloride.

NESHAP, 40 CFR Part 63 [Subpart EEEEE Applicable]

Subpart MMMM, National Emission Standards for Hazardous Air Pollutants for Surface Coating

of Miscellaneous Metal Parts and Products, establishes national emission standards for hazardous

air pollutants (NESHAP) for miscellaneous metal parts and products surface coating facilities.

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 29

This subpart does not apply to a coating operation conducted at a facility where the facility uses

only coatings, thinners and other additives, and cleaning materials that contain no organic HAP,

as determined according to §63.3941(a). Therefore, this facility is not subject to the rule.

Subpart ZZZZ, Reciprocating Internal Combustion Engines (RICE). This subpart affects

existing, new, or reconstructed stationary RICE located at a major or area source of HAP

emissions.

Existing compression ignition emergency stationary RICE with a site rating of more than 500

brake HP located at a major source of HAP emissions do not have to meet the requirements of

this subpart and of subpart A of this part. Therefore the Cummins emergency engine has no

requirements to meet under either of the aforementioned subparts.

Subpart EEEEE, National Emission Standards for Hazardous Air Pollutants (NESHAP) for Iron

and Steel Foundries, establishes national emission standards for hazardous air pollutants (HAPs)

for iron and steel foundries that are, or are part of, a major source of HAP emissions. This

subpart also establishes requirements to demonstrate initial and continuous compliance with the

emission limitations, work practice standards, and operation and maintenance requirements in

this subpart. Based on information in the existing Title V permit, this facility is a major source

of HAPs for purposes of this subpart and is therefore an affected source. The date of compliance

for existing facilities was April 23, 2007, and April 22, 2005, for the work practice standards.

§63.7690 - Emissions limitations. The facility is subject to the PM standards of §63.7690(a)(5).

For each pouring station at an existing iron and steel foundry, emissions discharged through a

conveyance to the atmosphere must not exceed either 0.010 gr/dscf of PM, or (ii) 0.0008 gr/dscf

of total metal HAP. Based on the definitions of conveyance, metal melting furnace (which does

not include the holding furnaces and ladles), only the pouring lines appear to be subject to an

emissions rate standard. Testing performed in August and October 2006 demonstrated

compliance with the standard of 0.01 gr/dscf for both pouring lines. The results of the testing are

summarized later in this memorandum.

The facility is also subject to the opacity standard of §63.7690(a)(7). For each building or

structure housing any iron and steel foundry emissions source at the iron and steel foundry,

fugitive emissions discharged to the atmosphere from foundry operations must not exhibit

opacity greater than 20 percent (6-minute average), except for one 6-minute average per hour

that does not exceed 27 percent opacity. The EHS Manager for the facility submitted by letter

dated April 30, 2007, certification that the initial opacity testing had been performed on that day

and that no opacity was observed.

The facility does not conduct triethylamine (TEA) cold box mold or core making TEA and is

therefore not subject to requirements associated with this pollutant.

§63.7700 - Work practice standards. The facility is subject to the requirements of this section

except for §63.7700(d) which pertains to furan core and mold making. See the following

discussion in §63.7744 for documenting compliance.

§63.7730 - Performance tests or other initial compliance demonstrations. As required by

§63.7(a)(2), an initial compliance performance test must be conducted no later than 180 calendar

days after the compliance date that is specified in §63.7683 (April 23, 2007). Initial compliance

with the work practice standards in §63.7700 must be demonstrated no later than 30 calendar

days after April 22, 2005.

§63.7731 - The facility is required to conduct subsequent performance tests to demonstrate

compliance with the opacity limit in §63.7690(a)(7) no less frequently than once every 6 months.

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 30

§63.7744 - Demonstrating continuous compliance with the work practice standards. The facility

must maintain records that document continuous compliance with the certification requirements

in §63.7700(b) or with the procedures in the scrap selection and inspection plan required in

§63.7700(c). Records documenting compliance with the scrap selection and inspection plan

must include a copy (kept onsite) of the procedures used by the scrap supplier for either

removing accessible mercury switches or for purchasing automobile bodies that have had

mercury switches removed, as applicable. For a scrap preheater at an existing iron and steel

foundry, the facility must operate and maintain each gas-fired preheater such that the flame

directly contacts the scrap charged to demonstrate continuous compliance with the requirement

§63.7700(e)(1). If the facility chooses to meet the work practice standard in §63.7700(e)(2), the

facility must keep records to document that the scrap preheater charges only material that is

subject to and in compliance with the scrap certification requirements in §63.7700(b). The

facility complies with this rule under §63.7700(b) and §63.7700(e)(1). A report dated August

13, 2008, for an FCE performed on June 17, 2008, states “An existing affected source must

comply with the work practice standards in § 63.7700 (b) or (c), as applicable, no later than April

22, 2005. Initial demonstration of compliance with these work practice standards is

accomplished by providing a certification with the initial notification of compliance status.

Semiannual compliance reports are then due January 31 and July 31 of each year or the required

information may be submitted with the TV Annual Compliance Certifications and Semiannual

Reports. The facility submitted the initial notification of compliance status on September 24,

2004, and the facility has submitted the semiannual compliance reports with the ACCs and

SARs.”

§63.7751 - Reports. The facility is subject to the requirements of this section.

§63.7752 - Records. The facility is subject to the requirements of this section.

§63.7753 – Records maintenance. The facility is subject to the requirements of this section.

Subpart DDDDD, National Emission Standards for Hazardous Air Pollutants for Industrial,

Commercial and Institutional Boilers and Process Heaters, establishes national emission

limitations and work practice standards for hazardous air pollutants (HAP) emitted from at major

sources of HAP. This subpart also establishes requirements to demonstrate initial and

continuous compliance with the emission limitations and work practice standards. The following

table lists the process combustion sources at the facility.

The following exclusions and definitions apply to this discussion.

Pursuant to §63.7491, the types of boilers and process heaters listed in paragraphs (a) through (n)

of this section are not subject to this subpart.

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 31

(d) A hot water heater as defined in this subpart.

(h) Any boiler or process heater that is part of the affected source subject to another subpart of

this part, such as boilers and process heaters used as control devices to comply with subparts JJJ,

OOO, PPP, and U of this part.

“Process heater means an enclosed device using controlled flame, and the unit's primary

purpose is to transfer heat indirectly to a process material. Process heaters are devices in which

the combustion gases do not come into direct contact with process materials.”

“Hot water heater means a closed vessel with a capacity of no more than 120 U.S. gallons in

which water is heated by combustion of gaseous, liquid, or biomass/bio-based solid fuel and is

withdrawn for use external to the vessel.”

The Venetta Furnace is covered by NESHAP EEEEE and is therefore not subject to this rule.

The Ladle Heaters are open flame into the ladles to dry them, which does not meet the definition

of a process heater and are therefore not affected sources under this rule.

The Tank Heaters meet the definition of hot water heater and are therefore not subject.

The Paint Oven does not meet the definition of process heater and is therefore not an affected

source under this rule.

The Shell Core Heaters do not meet the definition of process heater and are therefore not affected

sources under this rule.

The Core Ovens are covered by NESHAP EEEEE and are therefore not subject to this rule.

CAM, 40 CFR Part 64 [Applicable]

This part applies to any pollutant-specific emissions unit at a major source that is required to obtain

an operating permit, for any application for an initial operating permit submitted after April 18,

1998, that addresses “large emissions units,” or any application that addresses “large emissions

units” as a significant modification to an operating permit, or for any application for renewal of an

operating permit, if it meets all of the following criteria.

It is subject to an emission limit or standard for an applicable regulated air pollutant

It uses a control device to achieve compliance with the applicable emission limit or standard

It has potential emissions, prior to the control device, of the applicable regulated air

pollutant of 100 TPY or 10/25 TPY of a HAP

There are some emissions units for which the capacity rating is not known. Note that from Part

70, “Potential to emit” (PTE) means the maximum capacity of a stationary source to emit any air

pollutant under its physical and operational design. Any physical or operational limitation on the

capacity of a source to emit an air pollutant, including air pollution control equipment and

restrictions on hours of operation or on the type or amount of material combusted, stored, or

processed, shall be treated as part of its design if the limitation is enforceable by the

Administrator. Therefore, since the existing Title V permit has an enforceable limit on

throughput that is considered an operational limitation that is enforceable, the uncontrolled PTE

Page 32: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 32

must take that into consideration and the maximum capacity rating is not a factor in determining

the PTE. Based on this criteria, the following emissions units have potential pre-control

emissions of 100 TPY or more.

Potential pre-control emissions from A-3, the Simpson Multi-cooler, and M-15, the Vulcan Sand

Reclamation, exceed major source levels and each utilizes a baghouse to maintain compliance

with OAC 252:100-19, OAC 252:100-25, and the permit emissions limits. The definition of

control device excludes inherent process equipment. From 40 CFR Part 64, “Inherent process

equipment means equipment that is necessary for the proper or safe functioning of the process, or

material recovery equipment that the owner or operator documents is installed and operated

primarily for purposes other than compliance with air pollution regulations. Equipment that

must be operated at an efficiency higher than that achieved during normal process operations in

order to comply with the applicable emission limitation or standard is not inherent process

equipment. For the purposes of this part, inherent process equipment is not considered a control

device.” The applicant has realized the need to reuse the particulate fines collected in the

baghouse and has installed a return conveyor to re-circulate these fines to the process. Permit

No. 97-125-TV (M-2) determined that the baghouse for the Simpson Multi-cooler is inherent to

the process and CAM will not be required for the A-3. M-15 has an enforceable permit limit of

4.4 tons per year, controlled. Uncontrolled emissions at 95% control efficiency are 88 tons per

year. Therefore, CAM is required only for M-8. Following is an outline of applicant’s proposed

Chemical Accident Prevention Provisions, 40 CFR Part 68 [Not Applicable]

This facility will not process or store more than the threshold quantity of any regulated substance

(Section 112r of the Clean Air Act 1990 Amendments). The facility uses commercial natural gas

fuel which is comprised of mainly methane, a regulated substance per CAAA 90 Section 112(r).

However, this substance is not stored on-site. The small quantity which is in the pipelines on the

facility is much less than the 10,000 pound threshold and therefore is excluded from all

requirements including the Risk Management Plan.

Stratospheric Ozone Protection, 40 CFR Part 82 [Subparts A and F Applicable]

These standards require phase out of Class I & II substances, reductions of emissions of Class I

& II substances to the lowest achievable level in all use sectors, and banning use of nonessential

products containing ozone-depleting substances (Subparts A & C); control servicing of motor

vehicle air conditioners (Subpart B); require Federal agencies to adopt procurement regulations

which meet phase out requirements and which maximize the substitution of safe alternatives to

Class I and Class II substances (Subpart D); require warning labels on products made with or

containing Class I or II substances (Subpart E); maximize the use of recycling and recovery upon

disposal (Subpart F); require producers to identify substitutes for ozone-depleting compounds

under the Significant New Alternatives Program (Subpart G); and reduce the emissions of halons

(Subpart H).

Subpart A identifies ozone-depleting substances and divides them into two classes. Class I

controlled substances are divided into seven groups; the chemicals typically used by the

manufacturing industry include carbon tetrachloride (Class I, Group IV) and methyl chloroform

(Class I, Group V). A complete phase-out of production of Class I substances is required by

Page 34: OKLAHOMA DEPARTMENT OF ENVIRONMENTAL QUALITY · Initial metal melting is done in the three, 23-ton coreless electric induction furnaces. The melting operations are divided between

PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 34

January 1, 2000 (January 1, 2002, for methyl chloroform). Class II chemicals, which are

hydrochlorofluorocarbons (HCFCs), are generally seen as interim substitutes for Class I CFCs.

Class II substances consist of 33 HCFCs. A complete phase-out of Class II substances,

scheduled in phases starting by 2002, is required by January 1, 2030.

Subpart F applies to any person servicing, maintaining, or repairing appliances. This subpart

also applies to persons disposing of appliances, including small appliances and motor vehicle air

conditioners. In addition, this subpart applies to refrigerant reclaimers, technician certifying

programs, appliance owners and operators, manufacturers of appliances, manufacturers of

recycling and recovery equipment, approved recycling and recovery equipment testing

organizations, persons selling class I or class II refrigerants or offering class I or class II

refrigerants for sale, and persons purchasing class I or class II refrigerants. The purpose of this

subpart is to reduce emissions of class I and class II refrigerants and their substitutes to the

lowest achievable level by maximizing the recapture and recycling of such refrigerants during

the service, maintenance, repair, and disposal of appliances and restricting the sale of refrigerants

consisting in whole or in part of a class I and class II ODS in accordance with Title VI of the

Clean Air Act.

Standard Conditions included in the permit address required work practices to be used during the

maintenance, service, repair, or disposal of appliances, leak repair requirements, standards for

recycling and recovery equipment, technician certification, and recordkeeping requirements.

Additional applicable requirements are found in the rule.

SECTION VIII. COMPLIANCE

Inspection

A full compliance evaluation was conducted by Drake Hanna of AQD on June 9, 2016.

Violations related to requirements of NESHAP DDDDD including the applicability notification,

burner tune-up, and one-time energy assessment have been corrected. An area of concern related

to emissions reporting is pending the results of the next EI report.

Testing

Testing to confirm compliance with the standards for particulate matter (PM) set in NESHAP

Subpart EEEEE for pouring emissions was performed for the Green Sand Molding Line on

August 8 and 9, 2006, and for the No-Bake Molding Line on October 4, 2006. The facility was

in compliance. The standards and results of the tests are illustrated in the following table.

Quality section of the DEQ web page at www.deq.state.ok.us.

Information on all permit actions is available for review by the public in the Air Quality section of

the DEQ Web page: www.deq.state.ok.us/.

SECTION IX. SUMMARY

Based on the information submitted by the applicant and the estimated potential emissions

associated with this project, this modification does not result in a significant emission increase or

a significant net emission increase and the facility is not required to get a construction permit for

this modification.

Ambient air quality standards are not threatened at this site. There are no active Air Quality

compliance or enforcement issues that would affect the issuance of this permit. Issuance of the

operating permit is recommended contingent on Public and EPA reviews.
