American Castings, LLC
Pryor Foundry (Facility ID 802)
Pryor, Mayes County, Oklahoma
Located at Mid-America Industrial Park (Lat. 36.230/Long. -95.275)
Directions: From US Highway 412 in Mayes County, travel east from the
Chouteau exit on Highway 69 to Highway 412B, travel north
for approximately 4 miles into the Mid-America Industrial
Park. Facility is on the east side of the highway.
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.
PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 2
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.
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
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
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
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

EUG C - Core and Mold Operations
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
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
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.

Melting is accomplished using electric induction. No fuel combustion is involved and grease
and oils imported with the scrap are removed in the preheating process (discussed below).
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
Induction Furnaces, with an assumption that 95.6% is PM10, based on Table AP-42 12.10-9,
(1/95) “Particle Size Distribution Data”, Shakeout. PM10 emissions for tapping/refining were
calculated at 80% of the total PM emission obtained from the FIRE emission factors Version 5.0

Particulate Emissions from Material Handling/Preheating
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 (NOX, CO, VOC, and SO2) Emissions from Combustion Equipment
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
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.

All these emission units are fired on natural gas. AP-42 (7/98) Table 1.4-2 lists natural gas total
PM emissions to be 7.6 lbs/million scf or about 0.0076 lbs/MMBTU, which is in compliance. The
permit will require the furnaces and heaters to be fired only with commercial grade natural gas.
Section 19-12 limits particulate emissions from emission points in an industrial process based on
process weight rate, as specified in Appendix G. As shown in the following table, all emission
points are in compliance with Subchapter 19.

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,
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.
PERMIT MEMORANDUM 2014-2107-TVR2 DRAFT 28

SECTION VII. FEDERAL REGULATIONS
PSD, 40 CFR Part 52 [Not Applicable to This Project]
Final total facility emissions are greater than the threshold of 250 TPY of any single regulated
pollutant. However, emission increases from this project are less than the significance levels (40
TPY NOX, 100 TPY CO, 40 TPY VOC, 40 TPY SO2, 25 TPY PM10, and 75K TPY CO2e). Any
future increases of emissions must be evaluated for PSD if they exceed those levels.
NSPS, 40 CFR Part 60 [Not Applicable]
Subpart Z, Standards of Performance for Ferroalloy Production Facilities.
Subparts AA, Standards of Performance Steel Plants: Electric Arc Furnace.
Subparts AAa, Standards of Performance Steel Plants: Electric Arc Furnaces and Argon-Oxygen
Decarburization.
Subpart IIII, Stationary Compression Ignition Internal Combustion Engines, affects stationary
compression ignition (CI) internal combustion engines (ICE) based on power and displacement
ratings, depending on date of construction, beginning with those constructed after July 11, 2005.
Stationary CI ICE that commence construction after July 11, 2005 where the stationary CI ICE
are manufactured after April 1, 2006 and are not fire pump engines, or are manufactured as a
certified National Fire Protection Association (NFPA) fire pump engine after July 1, 2006 and
stationary CI ICE that modify or reconstruct their stationary CI ICE after July 11, 2005 are
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.

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
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
Compliance Assurance Monitoring.

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
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.

Fee Paid
Payment of $7,500 was submitted to satisfy the fee for a Title V permit renewal.
Tier Classification And Public Review
This application has been determined to be a Tier II based on the request to renew a Title V
permit. The applicant has submitted an affidavit that they are not seeking a permit for land use or
for any operation upon land owned by others without their knowledge. The affidavit certifies that
the applicant owns the real property.
The applicant will publish a “DEQ Notice Of Tier II Permit Application Filing” and a “DEQ
Notice Of Tier II Draft Permit” in a local newspaper for 30 day public review. In addition, a
copy of the draft permit will be available at the AQD office in Oklahoma City, and on the Air
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.
