PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Supersedes AO DAQE-AN0107920004-11 dated March 14, 2011
Is Derived From Additional Information dated October 30, 2024
REVIEWER COMMENTS

1. Comment regarding 10-Year Review: This is a 10-Year Review to update the language, format, and layout of the approval order to match current DAQ permitting standards. Currently, the only equipment remaining on site is the Rip Rap Plant and associated mobile generator. The source has requested to maintain the equipment list as is in the event the equipment is brought back for future production. Thus, there were no changes to the equipment or emissions at this time.
Additionally, the facility did not estimate the emissions of CO2 equivalent (CO2e) for the previous AO. It is assumed that CO2e emissions are primarily released from combustion units on site. The source has three (3) diesel fuel engines that can produce CO2e. The DAQ has estimated that CO2e emissions are 3,052 tons per year using AP-42 Table 3.3-1 and Table 3.4-1. The next time this
source goes through a modification, the equipment list and emissions should be updated to reflect the processes that are actually occurring on site and actual PM2.5 emissions. Because the source is located in Utah County which is a Nonattainment Area for PM2.5, R307-312 Aggregate Processing Operations for PM2.5 Nonattainment Areas shall apply to the source. Thus, the
visible emission opacities for the crushers, screens, and conveyors have been updated to reflect the more stringent conditions of R307-312. Other conditions of the AO have been updated. For example, Conditions II.B.4.a and II.B.4.a.1 of the prior AO have been separated into production and operation limits with their respective recordkeeping requirements. The same was done with Conditions II.B.5.a and II.B.5.a.1 of the prior AO. Additionally, Conditions II.B.2.d and II.B.2.e of the prior AO have been combined. [Last updated February 20, 2025]
2. Comment regarding Federal Rule Applicability: 40 CFR 60 Subpart OOO: Standards of Performance for Nonmetallic Mineral processing Plants In 1997 with a discussion with EPA Representative Keith Brown, it was decided that NSPS Subpart OOO did not apply to the crushers, screens, or conveyors on site. One of the reasons for this is that the slag that the facility is processing is not considered a non-metallic mineral. If the facility were to process other materials that would fit into the definition of a non-metallic mineral, like sand and gravel, then Subpart OOO would then apply. Because the source is only operating the Rip Rap Plant
and associated mobile generator, Subpart OOO applies to the crushers, screens, and conveyors associated in the rip rap process. Therefore, the source is currently subject to this subpart. 40 CFR 60 Subpart IIII: Standards of Performance for Stationary Compression Ignition Internal Combustion Engines 40 CFR 60 Subpart IIII applies to owners and operators of stationary compression ignition internal combustion engines that commence construction, reconstruction, or modification after July 11, 2005. The source operates a 306 hp engine for the rip rap plant that is subject to this subpart. 40 CFR 63 Subpart ZZZZ: National Emissions Standards for Hazardous Air Pollutants for

Engineer Review N107920005: Harsco Environmental- Plant #12 (Geneva Slag Operations) April 9, 2025 Page 13
Stationary Reciprocating Internal Combustion Engines 40 CFR 63 Subpart ZZZZ applies to owners and operators of stationary reciprocating internal
combustion engines at major or area sources of HAP emissions. This source is an area source of HAP emissions. Thus, the source is subject to this subpart. [Last updated February 20, 2025] 3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following:
1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous
Air Pollutants 4. Any Title IV affected source The source is not a major source nor a Title IV affected source. The source is not subject to 40 CFR 61. The source is subject to 40 CFR 60 (NSPS) Subpart OOO and 40 CFR 63 (MACT) Subpart
ZZZZ. Subpart ZZZZ exempts the source from the obligation to obtain a permit under Title V. However, Subpart OOO does not exempt the source from the obligation to obtain a permit under Title V. Therefore, Title V applies to the source as an area source. [Last updated February 20, 2025]

Abstract
Heckett MultiServ/Harsco Metals Americas (Harsco) has requested a modification to their current AO,
DAQE-AN0107920001 -09. The requested modification is for addition of a rip rap plant and one diesel
generator to their Geneva Steel plant. The generator will be used to supply power to the rip rap plant.
The location of this equipment will be at the current slag processing operation located at approximately
1500 North Geneva Road, Vineyard, Utah. This source is located in Utah County, which is a non-
attainment area of the NAAQS for PMJO. PM25, and a maintenance area for CO (Provo City Only). NSPS
40 CFR 60 Subpart A (General Provisions) and Subpart IIII (Standards of Performance for Stationary
Compression Ignition Internal Combustion Engines), MACT 40 CFR 63 Subpart A (General Provisions)
and Subpart ZZZZ (Nati onal Emission Standards for Hazardous Air Pollutants for Reciprocating Internal
Combusti on Engines) regulations apply to this source. Title V of the 1990 Clean Air Act does not apply
to this source as Subpai1 IIII and ZZZZ have an area source exemption from the Title V Program.
Emissions from the rip rap plant and generator will be limited by the amount of material processed and
fuel consumed by the generator. The erni ssion increases from the proposed addition of equipment are
below the 25 ton threshold necessary for Harsco to acquire emission offset credits.
As a result of these changes. the potential emissions, in tons per year, will change as foll ows: PM 10

ABSTRACT
Heckett MultiServ/Div. of Harsco Corp (Harsco) has requested a modification to their current AO
DAQE-AN0107920001-09. The requested modification is for addition of a rip rap plant and one diesel
generator to their Geneva Steel plant. The generator will be used to supply power to the rip rap plant.
The location of this equipment will be at the current slag processing operation located at approximately
1500 North Geneva Road, Vineyard, Utah. This source is located in Utah County, which is a non-
attainment area of the NAAQS for PM10, PM25, and a maintenance area for CO (Provo City Only). NSPS
40 CFR 60 Subpart A (General Provisions) and Subpart IIII (Standards of Performance for Stationary
Compression Ignition Internal Combustion Engines), MACT 40 CFR 63 Subpart A (General Provisions)
and Subpart ZZZZ (NESHAP for Reciprocating Internal Combustion Engines) regulations apply to this
source. Title V of the 1990 Clean Air Act does not apply to this source as Subpart IIII and ZZZZ have an
area source exemption from the Title V Program. Emissions from the rip rap plant and generator will be
limited by the amount of material processed and fuel consumed by the generator. The emission increases
from the proposed addition of equipment are below the 25 ton threshold necessary for Harsco to acquire
emission offset credits.
As a result of these changes, the potential emissions, in TPY, will change as follows: PM10 (Including
PM25) + 0.29, PM2.s + 0.16, NOx + 5.85, S02 + 0.0002, CO+ 0.47, VOC +0.19, HAPs + 0.005.
The sitewide emissions from this operation will result in the following potential emissions, in TPY: PM10
(Including PM25) = 84.18, PM2.5 = 14.37, NOx = 23.77, S02 = 0.28, CO= 5.23, VOC = 0.65, HAPs =
0.015.
The NOI for the above-referenced project has been evaluated and has been found to be consistent with the
requirements of UAC R307. Air pollution producing sources and/or their air control facilities may not be
constructed, installed, established, or modified prior to the issuance of an AO by the Executive Secretary
of the Utah Air Quality Board.
A 30-day public comment period will be held in accordance with UAC R307-401-7. A notification of the
intent to approve will be published in The Daily Herald on January 25, 2011. During the public comment
period the proposal and the evaluation of its impact on air quality will be available for the public to
review and provide comment. If anyone so requests a public hearing within 15 days of publication, it will
be held in accordance with UAC R307-401-7. The hearing will be held as close as practicable to the
location of the source. Any comments received during the public comment period and the hearing will be
evaluated. The proposed conditions of the AO may be changed as a result of the comments received.

to this source as Subpart IIII and ZZZZ have an area source exemption from the
Title V Program. Emissions from the rip rap plant and generator will be limited
by the amount of material processed and fuel consumed by the generator. The
emission increases from the proposed addition of equipment are below the 25 ton
threshold necessary for Harsco to acquire emission offset credits.
As a result of these changes, the potential emissions, in tons per year, will change
as follows: PM10 (Including PM25) + 0.29, PM2.5 + 0.16, NOx + 5.85, S02 +
0.0002, CO+ 0.47, VOC +0.19, HAPs + 0.005.
The sitewide emissions from this operation will result in the following potential
emissions, in tons per year: PM 10 (Including PM2.5) = 84.1 8, PM2.5 = 14.37, NOx
= 23.77, S02 = 0.28, CO= 5.23, VOC = 0.65, HAPs = 0.015.
The completed engineering evaluation and air quality impact analysis showed that the proposed project
meets the requirements of federal air quality regulations and the State air quality rules. The Executive
Secretary intends to issue an Approval Order pending a 30-day public comment period. The project
proposal, estimate of the effect on local air quality and draft Approval Order are available for public
inspection and comment at the Utah Division.of Air Quality, 195 North 1950 West, Salt Lake City, UT
84116. Written comments received by the Division at this same address on or before February 24, 2011
will be considered in making the final decision on the approval/disapproval of the proposed project. Email
comments will also be acce pted at [e-mail]. If anyone so requests to the Executive Secretary at
DAQE-NN01077920004-l l

AT THE OLD GENEVA STEEL PLANT
1.0 INTRODUCTION
Meteorological Solutions Inc. (MSI) was retained by Harsco Metals to prepare a Notice
of Intent (NOI) to address proposed modifications to Harsco Metals slag processing operations at
the old Geneva Steel site in Vineyard, Utah. This NOI addresses the increase in emissions from
the addition of a 362 HP Tier 1 diesel engine and an 850 ton per hour rip rap plant. Harsco
Metals current Approval Order for slag processing operations at the old Geneva Steel plant is
DAQE-INO 107920001-08.
1.1 Facility Description
The Harsco Metals operation being performed at the old Geneva Steel site is located in
Utah County at 1500 North Geneva Road, Vineyard, Utah. The Universal Transverse Mercator
(UTM) coordinates in NAD 27 for the site are:
• 436,130 meters East
• 4,463,260 meters North
An aerial view of the site is presented in Figure 1.1. Figure 1.2 presents the site location
on a topographical map.
When these modifications are operational, operating hours for the rip rap plant and
generator are anticipated to be 16 hours per day, five days per week, and 52 weeks per year.

2.0 PROCESS DESCRIPTION
Harsco Metals operates a slag repro cessing facility at the old Geneva Steel plant site in
Vineyard, Utah. The slag reprocessing facility consists of an open hearth slag plant and blast
furnace slag plant ( consisting of crushers, screens, conveyor transfer points and diesel
generators). For this NOi, an 850 ton per hour rip rap plant equipped with a vibrating grizzly
feeder will screen products to stockpiles and a 362 HP Tier 1 diesel engine, which will provide
the power to the rip rap plant, are proposed. Figure 2.1 presents a process flow diagram for the
rip rap plant.

3.0 AIR EMISSIONS
Potential to emit (PTE) emission estimates were provided by Harsco Metals. These
emission estimates are based on manufacturer and vendor data, EPA guidance as published in
Compilation of Air Pollution Emission Factors, Volume I: Stationary Point and Area Sources or
AP-42 1, specifically Section 11.19.2 Crushed Stone Processing and Pulverized Mineral
Processing, fuel type, and anticipated operating hours. The proposed generator will meet EPA
Tier 1 standards. Potential controlled emissions for the rip rap plant and generator are presented
in Table 3-1 and in Appendix A. These PTE emissions are based on a maximum operating
schedule of 16 hours per day, five days per week, and 52 weeks per year or 4,160 operating
hours annually. Emissions from front end loaders and storage pile are included in Harsco's
current approval order.

Besides the inherent moisture of the material, application of water through use of a water
truck will be used as needed to minimize fugitive emissions.
For the generator, available control measures include proper engine maintenance,
combustion controls, and use of ultra-low sulfur fuel. No add-on pollution control equipment
such as selective catalytic reduction or catalytic oxidation systems is proposed.

4.0 BEST AVAILABLE CONTROL TECHNOLOGY
Per Utah Air Rules R307-400, best available control technology (BACT) is defined as an
emissions limitation (including a visible emissions standard) based on the maximum degree of
reduction for each air contaminant which would be emitted from any proposed stationary source
or modification which the executive secretary, on a case-by-case basis, taking into account
energy, environmental, and economic impacts and other costs, determines is achievable for such
source or modification through application of production processes or available methods,
systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion
techniques for control of such pollutant. BACT analyses for the emissions from the proposed
generator are discussed in the following sections.
4.1 BACT Analysis for Fugitive PM10 Sources
Screening and conveying of slag material creates fugitive PM10 emissions. The most
common control technology used to control fugitive PM 1o is the application of water to maintain
moisture throughout the screening process. Wet scrubbers, cyclones, and ESPs are typically
eliminated from the BACT analysis because these emission control technologies are either
infeasible in a temperature variable outdoor environment, or because they are not considered
effective for total particulate control for screening operation. In most cases, baghouse control is
also eliminated from the BACT analysis before energy, economic, or environmental impacts are
addressed due to operational constraints and is cost prohibitive for screening operations. Thus,
the final options that would be available for BACT include:
• Inherent Moisture/No Additional Control; and
• Water Spray Control.
Harsco Metals 4-1 NOi
The Inherent Moisture/No Additional Control option was eliminated from the
technologies evaluated for BACT, as it could result in emissions of PM10 which may exceed
UDAQ fugitive opacity requirements. After removing those options that would be operationally
restrictive (wet scrubbers, cyclones, and ESPs), cost prohibitive options (baghouses) and the
options that would not provide adequate control (relying on inherent moisture of material), the
only BACT option is water application. Therefore, the application of water is defined as BACT
for the rip rap plant.
4.2 BACT Analysis for Generators
The proposed industrial engine consists of a diesel-powered generator, which has the
potential to create PM10, PM2.s, NOx, S02, CO, VOCs, and HAPs.
BACT for industrial engines of the sizes proposed has been established as good process
design and sound operating practices. Good process design includes proper and preventative
maintenance of the engines to ensure high efficiency of fuel combustion. Sound operating
practices for the engines involves using low sulfur-fuels and operating the engines only at the
load necessary.

The definitions and general requirements found in R307-101 including R307-101-3,
version of code of federal regulations incorporated by reference will apply to the Harsco Metals
proposed modifications.
Harsco Metals 5-1 NOi
5.2 R307-102 -General Requirements: Broadly Applicable Requirements
Emission of air contaminants in sufficient quantities to cause air pollution as defined in
R307-101-2 is prohibited. The State statute provides for penalties up to $50,000/day for violation
of State statutes, regulations, rules or standards. In addition, the owner or operator of any
stationary air contaminant source in Utah shall furnish to the Board the periodic reports and any
other information as the Board may deem necessary to determine whether the source is in
compliance with Utah and Federal regulations and standards.
Any person submitting information pursuant to R307-102 may request that such
information be treated as a trade secret or on a confidential basis, in which case the Executive
Secretary and Board shall so treat such information. If no claim is made at the time of
submission, the executive secretary may make the information available to the public without
further notice.
5.3 R307-107 General Requirements: Unavoidable Breakdown
The unavoidable breakdown provisions of R307-l 07 will apply to the Harsco Metals slag
reprocessing operation. A breakdown for any period longer than 2 hours will be reported to the
Executive Secretary within 3 hours of the beginning of the breakdown if reasonable, but in no
case longer than 18 hours after the beginning of the breakdown. Within 7 calendar days of the
beginning of any breakdown of longer than 2 hours, a written report shall be submitted to the
Executive Secretary which shall include the cause and nature of the event, estimated quantity of
pollutant (total and excess), time of emissions and steps taken to control the emissions and to
prevent recurrence.
5.4 R307-150 -Emission Inventories
Emission inventories will be submitted on or before ninety days following the effective
date of this rule and thereafter on or before April 15 of each year following the calendar year for
which an inventory is required.
Harsco Metals 5-2 NOi
Harsco Metals will submit an inventory every third year beginning with calendar year
2002 for all emissions units including fugitive emissions. The inventory will include PM10,
PM2.s, oxides of sulfur, oxides of nitrogen, carbon monoxide, volatile organic compounds,
ammonia, other chargeable pollutants, and hazardous air pollutants not exempted in R307-l 50-8.
For each pollutant, the inventory shall include the rate and period of emissions, excess or
breakdown emissions, startup and shut down emissions, the specific emissions unit which is the
source of the air pollution, composition of air contaminant, type and efficiency of the air
pollution control equipment, and other information necessary to quantify operation and
emissions and to evaluate pollution control efficiency. The emissions of a pollutant will be
calculated using the source's actual operating hours, production rates, and types of materials
processed, stored, or combusted during the inventoried time period.
5.5 R307-165 -Emission Testing
Emission testing is required at least once every five years of all sources with established
emission limitations specified in approval orders issued under R307-401.
5.6 R307-201 -Emission Standards: General Emission Standards
It is anticipated that the Harsco Metals operation will be subject to the visible emission
standards presented in R307-201. Emissions from the diesel engines, except locomotives,
manufactured after January 1, 1973 shall be of a shade or density no darker than 20% opacity,
except for station motion no farther than 100 yards or for stationary operation not exceeding
three minutes in any hour. Visible emissions exceeding the opacity standards for short time
periods as the result of initial warm up, start-up or shutdown of a facility, installation or
operation, or unavoidable combustion irregularities which do not exceed three minutes in length
shall not be deemed a violation provided that the Executive Secretary finds that adequate control
technology has been applied.
Harsco Metals 5-3 NOi
-
Harsco Metals shall minimize visible and non-visible emissions during start-up or
shutdown of a facility, installation, or operation through the use of adequate control technology
and proper procedures. Emissions shall be brought into compliance with these requirements by
reduction of the total weight of contaminants discharged per unit of time rather than by dilution
of emissions with clean air. EPA Method 9 will be utilized to determine opacity from stationary
sources.
5.7 R307-210 -Stationary Sources
The provisions of 40 Code of Federal Regulations (CFR) Part 60, effective on July 1,
2006, except for Subparts Cb, Cc, Cd, Ce, BBBB, DDDD, and HHHH, are incorporated by
reference. The New Source Performance Standards as found in 40 CFR Part 60 that Harsco
Metals will be subject to include Subpart A and Subpart IHI.
The provisions of 40 CFR Part 60 Subpart A applies to each affected facility as specified
in the relevant NSPS regulation for that source type. Subpart A contains general requirements
for notifications, monitoring, performance testing, reporting, recordkeeping, and operation and
maintenance provisions.
40 CFR Part 60 Subpart IHI, Standards of Performance for Stationary Compression
Ignition Internal Combustion Engines, will apply to the 362 HP diesel generator.
5.8 R307-305 -Nonattainment and Maintenance Areas for PM10: Emission Standards
This rule establishes emission standards and work practices for sources located in PM10
nonattainment and maintenance areas to meet the reasonably available control measures. This
includes visible emissions from existing installations except diesel engines shall be of a shade or
density no darker than 20% opacity. Visible emissions shall be measured using EPA Method 9.
Emissions from diesel engines, except locomotives, shall be of a shade or density no darker than
20% opacity, except for starting motion no farther than 100 yards or for stationary operation not
exceeding three minutes in any hour.
Harsco Metals 5-4 NOi
-
5.9 R307-309 -Nonattainment and Maintenance Areas for PM10: Fugitive Emissions
and Fugitive Dust
Fugitive emissions from any source shall not exceed 15 % opacity. Opacity observations
of emissions from stationary sources shall be conducted in accordance with EPA Method 9.
Opacity caused by fugitive du st shall not exceed: (a) 10% at the property boundary; and (b) 20%
on site. Opacity shall not apply when the wind speed exceeds 25 miles per hour and the owner or
operator is taking appropriate actions to control fugitive dust. If the source has a fugitive du st
control plan approved by the executive secretary, control measures in the plan are considered
appropriate. Any person owning or operating a new or existing source of fugitive dust, including
storage, hauling or handling operations, or engaging in clearing or leveling of land one-quarter
acre or greater in size, earthmoving, excavation, or movement of trucks or construction
equipment over cleared land one-quarter acre or greater in size or access haul roads, or engaging
in demolition activities including razing homes, buildings or other structures shall submit a plan
to control fugitive dust to the executive secretary no later than 30 days after the source becomes
subject to R307-309.
5.10 R307-401 -Permit: New and Modified Sources
This rule establishes the application and permitting requirements for new installations
and modifications to existing installations throughout the State of Utah. According to R307-401
any person intending to make modifications or relocate an existing installation which will or
might reasonably be expected to increase the amount or change the effect of, or the character of,
air contaminants di scharged, so that such installation may be expected to become a source or
indirect source of air pollution shall submit to the executive secretary a NOI and receive an
approval order prior to initiation of construction.
The NOI shall include the information described in R307-401-5 to determine whether the
proposed construction will be in accord with applicable requirements of these rules. Within 30
days after receipt of a NOI, or any additional information necessary to the review, the executive
secretary shall advise the applicant of any deficiency in the NOI or the information submitted.
Harsco Metals 5-5 NOi
6.0 OFFSET REQUIREMENTS AND EMISSION IMPACT ANALYSIS
New sources which have a potential to emit, or modified sources which are located in or
impact a PM10 nonattainment area and produce an emission increase equal to or exceeding the
tonnage total of combined PM10, sulfur dioxide, and oxides of nitrogen are required to obtain an
enforceable offsets:
• For a total of 50 tons/year or greater, an offset of 1.2: 1 of the emission increase is
required.
• For a total of25 tons/year but less than 50 tons/year, an offset of 1:1 of the emission
increase is required.
For the offset determinations, PM10, sulfur dioxide, and oxides of nitrogen shall be
considered on an equal basis. For the proposed modification, the total of PM10, sulfur dioxide,
and oxides of nitrogen emissions was estimated to be 14.1 tons. Thus, based on the PTE
emissions from the proposed modification, offset requirements will not be met. In addition, the
PTE emissions from the proposed modification are well below the criteria pollutant thresholds
that are required to conduct a dispersion modeling analysis.
Emissions of HAPS were calculated and HAP air quality analysis was conducted in
accordance with Utah Administrative Code R307-410-5. To determine which HAPs, if any,
required modeling, the UDAQ's 2007 ACGIH Threshold Limit Values (TL Vs), Toxic Screening
Levels (TS Ls) and Emission Threshold Values (ETV s) spreadsheet was utilized. Based on the
methodology in R307-410-5, the emission rates of all HAPs were below the ETV levels; thus, no
dispersion modeling of HAPs was required.

SUMMARY OF NOTICE OF INTENT INFORMATION
Description of Proposal:
Additions: Harsco operates a slag processing plant at the old Geneva Steel site in Vinyard, Utah. The slag
reprocessing plant consists of an open hearth slag plant and blast furnace slag plant (consisting of
crushers, screens, conveyor transfer points and diesel generators). To assist in processing of slag
material, a rip rap plant (consisting of a vibrating grizzly feeder for screening products to stockpiles and
three conveyors) and a portable ·diesel generator, for power generation, will be installed.
The rip rap plant wi II be limited to screening 1,500,000 tons of processed slag material.
The amount of fuel consumed by the 306 HP generator wi II be Ii mited to 58,500 gallons per year.
Deletions:
All mobile source emissions associated with haul roads have been calculated in previous permits. The
amount of vehicle miles traveled will be the limiting factor associated with the on-site haul road activity
and a permit condition will be applicable to this activity.
Summary of Emission Changes and Totals:
The emissions listed below are an estimate of the total potential emissions from the source. Some
rounding of emissions is possible. All values given are in tons per year.

assured with the use of a 20% opacity limit on the generator. U1tra low sulfur fuel will be
considered that the sulfur content of fu el will not exceed 15 ppm. [Last updated December 7,
2010]
2. BACT review regarding Rip Rap Plant -Haul Road Traffic
BACT for the haul road traffic associated with the Rip Rap plant will remain as is for the current
permit. A Fugitive Dust Control Plan must be complied with that ensures water trucks will be
utilized for control of fu giti ve dust emiss ions from the roadways. Al so in addition to water
trucks, the amount of vehicle miles traveled is limited to 188,887 miles per rolling 12-month
period. This limitation is a required permit condition. [Last updated December 7, 2010]
3. BACT review regarding Rip Rap Plant -Vibrating Grizzly and Convey ors
BACT for the Vibrating Grizzly and Conveyors wi ll be the use of water spray control. Water
sprays shall be installed as necessary on conveyor transfer and drop points as necessary to
ensure the 20% opacity limitations of th is permit are not exceeded. [Last updated December 7,

l. Comment on an item originating in_ regarding Slag Reprocessing Faci lity
NSPS 000 Applicability: In 1997 with a discussion with EPA Representative Keith Brown, it
was decided that NSPS Subpart 000 did not apply to the crushers, screens, or conveyors on
site. One of the reasons for this is that the slag that the facility is processing is not considered a
non-metallic mineral. If the facility were to process other materials that would fit into the
definition of a non-metallic mineral, like sa nd and gravel, then Subpart 000 would then apply.
[Last updated June 17, 2010]
2. Comment on an item originating in regarding Slag Reprocessing Facility
Tailpipe Emissions: The existing AO contained emissions and limitations for mobile equipment.
DAQ does not regulate these emissions with the issuance of AOs; therefore, these limitations
were removed from the AO and the emissions from the PTE totals were also removed. [Last
updated June 17, 2010]
3. Comment on an item originating in regarding Rip Rap Plant
Haul Road Emissions from Rip Rap Plant installation.
: The previous permitting actions took into consideration 188,889 vehicle miles traveled (vmt)
for haul trucks, loader activity and pot carriers. With the addition of the Rip Rap plant their will
be a shift in operations. Less activity wi ll take place in the areas of the Blast Furnace and Open
Hearth slag plants. This shift will create the ability for Harsco to include all haul, loader, and
pot carrier traffic under the cun-ent emissions calculated for previous AO's. Their will be an
additional condition in the permit to limit the vmt on-site from these vehicl es to what has been
calculated for the previous AOs. [Last updated December 2, 2010)

1.0 INTRODUCTION
Meteorological Solutions Inc. (MSI) was retained by Harsco Metals to prepare a Notice
of Intent (NOI) to address proposed modifications to Harsco Metals slag processing operations at
the old Geneva Steel site in Vineyard, Utah. This NOI addresses the increase in emissions from
the addition of a 306 HP diesel engine and an 850 ton per hour rip rap plant. Harsco Metals
current Approval Order for slag processing operations at the old Geneva Steel plant is DAQE-
IN0107920001-08.
1.1 Facility Description
The Harsco Metals operation being performed at the old Geneva Steel site is located in
Utah County at 1500 North Geneva Road, Vineyard, Utah. The Universal Transverse Mercator
(UTM) coordinates in NAD 27 for the site are:
• 436,130 meters East
• 4,463,260 meters North
An aerial view of the site is presented in Figure 1.1. Figure 1.2 presents the site location
on a topographical map.
When these modifications are operational, operating hours for the rip rap plant and
generator will be limited to 3900 hours in any 12-month rolling period.

2.0 PROCESS DESCRIPTION
Harsco Metals operates a slag reprocessing facility at the old Geneva Steel plant site in
Vineyard, Utah. The slag reprocessing facility consists of an open hearth slag plant and blast
furnace slag plant ( consisting of crushers, screens, conveyor transfer points and diesel
generators). For this NOI, an 850 ton per hour rip rap plant equipped with a vibrating grizzly
feeder will screen products to stockpiles and a 306 HP diesel engine, which will provide the
power to the rip rap plant, are proposed. Figure 2.1 presents a process flow diagram for the rip
rap plant.

3.0 AIR EMISSIONS
Potential to emit (PTE) emission estimates were provided by Harsco Metals. Generator
emission estimates are based on manufacturer specific engine data and EPA guidance as
published in Compilation of Air Pollution Emission Factors, Volume I: Stationary Point and
Area Sources or AP-42 1 Section 3.3 Gasoline and Diesel Engines and proposed operating hours.
For the rip rap plant, emission estimates were based on AP-42 Section 11.19.2 Crushed Stone
Processing and Pulverized Mineral Processing and anticipated operating hours. Potential
controlled emissions for the rip rap plant and generator are presented in Table 3-1 and in
Appendix A. Engine specific data are also presented in Appendix A. PTE emissions are based
on a maximum of 3,900 operating hours in any 12-month rolling period.
Fugitive particulate estimates in the existing AO are based on 2,800,000 tons of material
throughput and 108,000 vehicle miles traveled (VMT) by the loaders/haul trucks and 80,889
VMT for the pot carriers. Due to no steel made and changes in raw material location, Harsco's
current operating scenario has resulted in only 1,400,000 tons of material processed and 77,000
VMT. •
The proposed rip rap plant and associated operations will add 1,500,000 tons of material
processed and approximately 40,000 VMT to the current operating scenario. Total '(MT for the
current and proposed operations is estimated to be 117,000 VMT which is well below the
188,889 VMT that emissions in the current approval order were based on.

Besides the inherent moisture of the material, application of water through use of a water
truck will be used as needed to minimize fugitive emissions.
For the generator, available control measures include proper engine maintenance,
combustion controls, and use of ultra-low sulfur fuel. No add-on pollution control equipment
such as selective catalytic reduction or catalytic oxidation systems is proposed.
Harsco Metals 3-2 NOi
4.0 BEST AVAILABLE CONTROL TECHNOLOGY
Per Utah Air Rules R307-400, best available control technology (BACT) is defined as an
emissions limitation (including a visible emissions standard) based on the maximum degree of
reduction for each air contaminant which would be emitted from any proposed stationary source
or modification which the executive secretary, on a case-by-case basis, taking into account
energy, environmental, and economic impacts and other costs, determines is achievable for such
source or modification through application of production processes or available methods,
systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion
techniques for control of such pollutant. BACT analyses for the emissions from the proposed
generator are discussed in the following sections.
4.1 BACT Analysis for Fugitive PM10 Sources
Screening and conveying of slag material creates fugitive PM10 emissions. The most
common control technology used to control fugitive PM10 is the application of water to maintain
moisture throughout the screening process. Wet scrubbers, cyclones, and ESPs are typically
eliminated from the BACT analysis because these emission control technologies are either
infeasible in a temperature variable outdoor environment, or because they are not considered
effective for total particulate control for screening operation. In most cases, baghouse control is
also eliminated from the BACT analysis before energy, economic, or environmental impacts are
addressed due to operational constraints and is cost prohibitive for screening operations. Thus,
the fmal options that would be available for BACT include:
• Inherent Moisture/No Additional Control; and
• Water Spray Control.
Harsco Metals 4-1 NO!
The Inherent Moisture/No Additional Control option was eliminated from the
technologies evaluated for BACT, as it could result in emissions of PM10 which may exceed
UDAQ fugitive opacity requirements. After removing those options that would be operationally
restrictive (wet scrubbers, cyclones, and ESPs), cost prohibitive options (baghouses) and the
options that would not provide adequate control (relying on inherent moisture of material), the
only BACT option is water application. Therefore, the application of water is defined as BACT
for the rip rap plant.
4.2 BACT Analysis for Generators
The proposed diesel-fired generator has the potential to create PM10, PM2.s, NOx, S02,
CO, VOCs, and HAPs emissions.
BACT for industrial engines of the sizes proposed has been established as good process
design and sound operating practices. Good process design includes proper and preventative
maintenance of the engines to ensure high efficiency of fuel combustion. Sound operating
practices for the engines involves using low sulfur-fuels and operating the engines only at the
load necessary.

version of code of federal regulations incorporated by reference will apply to the Harsco Metals
proposed modifications.
Harsco Metals 5-1 NO!
5.2 R307-102 -General Requirements: Broadly Applicable Requirements
Emission of air contaminants in sufficient quantities to cause air pollution as defined in
R307-101-2 is prohibited. The State statute provides for penalties up to $50,000/day for violation
of State statutes, regulations, rules or standards. In addition, the owner or operator of any
stationary air contaminant source in Utah shall furnish to the Board the periodic reports and any
other information as the Board may deem necessary to determine whether the source is in
compliance with Utah and Federal regulations and standards.
Any person submitting information pursuant to R307-102 may request that such
information be treated as a trade secret or on a confidential basis, in which case the Executive
Secretary and Board shall so treat such information. If no claim is made at the time of
submission, the executive secretary may make the information available to the public without
further notice.
5.3 R307-107 General Requirements: Unavoidable Breakdown
The unavoidable breakdown provisions of R307-107 will apply to the Harsco Metals slag
reprocessing operation. A breakdown for any period longer than 2 hours will be reported to the
Executive Secretary within 3 hours of the beginning of the breakdown if reasonable, but in no
case longer than 18 hours after the beginning of the breakdown. Within 7 calendar days of the
beginning of any breakdown of longer than 2 hours, a written report shall be submitted to the
Executive Secretary which shall include the cause and nature of the event, estimated quantity of
pollutant (total and excess), time of emissions and steps taken to control the emissions and to
prevent recurrence.
5.4 R307-150 -Emission Inventories
Emission inventories will be submitted on or before ninety days following the effective
date of this rule and thereafter on or before April 15 of each year following the calendar year for
which an inventory is required.
Harsco Metals 5-2 NOi
Harsco Metals will submit an inventory every third year beginning with calendar year
2002 for all emissions units including fugitive emissions. The inventory will include PM10,
PM2_5, oxides of sulfur, oxides of nitrogen, carbon monoxide, volatile organic compounds,
ammonia, other chargeable pollutants, and hazardous air pollutants not exempted in R307-150-8.
For each pollutant, the inventory shall include the rate and period of emissions, excess or
breakdown emissions, startup and shut down emissions, the specific emissions unit which is the
source of the air pollution, composition of air contaminant, type and efficiency of the air
pollution control equipment, and other information necessary to quantify operation and
emissions and to evaluate pollution control efficiency. The emissions of a pollutant will be
calculated using the source's actual operating hours, production rates, and types of materials
processed, stored, or combusted during the inventoried time period.
5.5 R307-165 -Emission Testing
Emission testing is required at least once every five years of all sources with established
emission limitations specified in approval orders issued under R307-401.
5.6 R307-201 -Emission Standards: General Emission Standards
It is anticipated that the Harsco Metals operation will be subject to the visible emission
standards presented in R307-201. Emissions from the diesel engines, except locomotives,
manufactured after January 1, 1973 shall be of a shade or density no darker than 20% opacity,
except for station motion no farther than 100 yards or for stationary operation not exceeding
three minutes in any hour. Visible emissions exceeding the opacity standards for short time
periods as the result of initial warm up, start-up or shutdown of a facility, installation or
operation, or unavoidable combustion irregularities which do not exceed three minutes in length
shall not be deemed a violation provided that the Executive Secretary finds that adequate control
technology has been applied.
Harsco Metals 5-3 NO!
Harsco Metals shall minimize visible and non-visible emissions during start-up or
shutdown of .:t facility, installation, or operation through the use of adequate control technology
and proper procedures. Emissions shall be brought into compliance with these requirements by
reduction of the total weight of contaminants discharged per unit of time rather than by dilution
of emissions with clean air. EPA Method 9 will be utilized to determine opacity from stationary
sources.
5.7 R307-210 -Stationary Sources
The provisions of 40 Code of Federal Regulations (CFR) Part 60, effective on July 1,
2006, except for Subparts Cb, Cc, Cd, Ce, BBBB, DDDD, and HHHH, are incorporated by
reference. The New Source Performance Standards as found in 40 CFR Part 60 that Harsco
Metals will be subject to include Subpart A and Subpart IIII.
The provisions of 40 CFR Part 60 Subpart A applies to each affected facility as specified
in the relevant NSPS regulation for that source type. Subpart A contains general requirements
for notifications, monitoring, performance testing, reporting, record.keeping, and operation and
maintenance provisions.
40 CFR Part 60 Subpart IIII, Standards of Performance for Stationary Compression
Ignition Internal Combustion Engines, will apply to the 306 HP diesel generator.
5.8 R307-305 -Nonattainment and Maintenance Areas for PM10: Emission Standards
This rule establishes emission standards and work practices for sources located in PM10
nonattainment and maintenance areas to meet the reasonably available control measures. This
includes visible emissions from existing installations except diesel engines shall be of a shade or
density no darker than 20% opacity. Visible emissions shall be measured using EPA Method 9.
Emissions from diesel engines, except locomotives, shall be of a shade or density no darker than
20% opacity, except for starting motion no farther than 100 yards or for stationary operation not
exceeding three minutes in any hour.
Harsco Metals 5-4 NOi
5.9 R307-309 -Nonattainment and Maintenance Areas for PM10: Fugitive Emissions
and Fugitive Dust
Fugitive emissions from any source shall not exceed 15% opacity. Opacity observations
of emissions from stationary sources shall be conducted in accordance with EPA Method 9.
Opacity caused by fugitive dust shall not exceed: (a) 10% at the property boundary; and (b) 20%
on site. Opacity shall not apply when the wind speed exceeds 25 miles per hour and the owner or
operator is taking appropriate actions to control fugitive dust. If the source has a fugitive dust
control plan approved by the executive secretary, control measures in the plan are considered
appropriate. Any person owning or operating a new or existing source of fugitive dust, including
storage, hauling or handling operations, or engaging in clearing or leveling of land one-quarter
acre or greater in size, earthmoving, excavation, or movement of trucks or construction
equipment over cleared land one-quarter acre or greater in size or access haul roads, or engaging
in demolition activities including razing homes, buildings or other structures shall submit a plan
to control fugitive dust to the executive secretary no later than 30 days after the source becomes
subject to R307-309.
5.10 R307-401 -Permit: New and Modified Sources
This rule establishes the application and permitting requirements for new installations
and modifications to existing installations throughout the State of Utah. According to R307-401
any person intending to make modifications or relocate an existing installation which will or
might reasonably be expected to increase the amount or change the effect of, or the character of,
air contaminants discharged, so that such installation may be expected to become a source or
indirect source of air pollution shall submit to the executive secretary a NOI and receive an
approval order prior to initiation of construction.
The NOI shall include the information described in R307-401-5 to determine whether the
proposed construction will be in accord with applicable requirements of these rules. Within 30
days after receipt of a NOI, or any additional information necessary to the review, the executive
secretary shall advise the applicant of any deficiency in the NOI or the information submitted.

6.0 OFFSET REQUIREMENTS AND EMISSION IMP ACT ANALYSIS
New sources which have a potential to emit, or modified sources which are located in or
impact a PM10 nonattainment area and produce an emission increase equal to or exceeding the
tonnage total of combined PM10, sulfur dioxide, and oxides of nitrogen are required to obtain an
enforceable offsets:
• For a total of 50 tons/year or greater, an offset of 1.2:1 of the emission increase is
required.
• For a total of25 tons/year but less than 50 tons/year, an offset of 1:1 of the emission
increase is required.
For the offset determination, emission increases contained in the current December 2008
Approval Order (DAQE-IN0107920001-08) and proposed emission increases contained in this
NOi were reviewed since the emission increase requests have occurred within a two-year period.
For the offset determinations, PM10, sulfur dioxide (S02), and oxides of nitrogen (NOx) are
considered on an equal basis. For the proposed modification, the total of PM10, S02, and NOx
emissions was estimated to be 6.14 tons. The total PM10, S02, and NOx emissions, as listed in
DAQE-IN0107920001-08, are 18.76 tons (PM10 + 0.56, NOx + 17.92, and S02 +0.28). Thus,
total emission increases of recently permitted emissions and proposed emission increases are
24.9 tons. This is below the offset threshold of 25 tons. In addition, the PTE emissions from the
proposed modification are below the criteria pollutant thresholds that are required to conduct a
dispersion modeling analysis.
Emissions of HAPS were calculated and HAP air quality analysis was conducted in
accordance with Utah Administrative Code R307-410-5. To determine which HAPs, if any,
required modeling, the UDAQ's 2007 ACGIH Threshold Limit Values (TLVs), Toxic Screening
Levels (TSLs) and Emission Threshold Values (ETV s) spreadsheet was utilized. Based on the
methodology in R307-410-5, the emission rates of all HAPs were below the ETV levels; thus, no
dispersion modeling of HAPs was required.

RE: Revised NOi for Harsco Metals
I'm just getting back from being out of town. As per the VMT information, I
understand that these estimates were in the previous NOi that was not
prepared by MSI. According to Harsco, the VMT's currently permitted for are
mu~~ higher than are actually occurring and with the requested changes, any
add1t1onal VMT's would still be covered by the original permitted estimates.
If you need calculations, I'll have to pull something together later in the
week.
Just let me know how to proceed and have a great day!
Sincerely,
Linda Conger

Subject: Re: Revised NOi for Harsco Metals
Hi Linda,
One more quick question for you as I want to make sure I understand this
correctly.
In Section 3.0 Air Emissions of your revised NOi document you have addressed
Fugitive emissions from 108,000 vehicle miles traveled (VMT) (loaders/haul
trucks) and 80,889 VMT by Pot Carriers for a total of 188,889 VMT. This
number is what fugitive haul road/loader/pot carrier emissions were
calculated based upon.
You are also stating that under the current operating scenario only 77,000
VMT are being utilized.
Under the proposed scenario there would only be approximately 40,000 VMT
necessary for the 1,500,000 tons of processed material. Therefore, the
approximate 117,000 VMT necessary to include the current operations and
proposed operation is the estimated VMT for both operations.
In order to ensure no emission increase will occur I need to see a copy of
the calculations which were used for the determination of emissions from the
188,889 VMT. For some reason the file here does not contain those numbers.
If you could provide those to me that would be great.
I appreciate your assistance.
Jon

Jon,
Please find attached the revised NOi for Harsco Metals. As you will see in
this NOi, Harsco will utilize a 306HP diesel generator and has limited the
operating hours for the generator and rip rap plant to 3900 based on a
12-month rolling average. Generator emission estimates are based on
manufacturer engine performance data adjusted for elevation. In addition, a
discussion of the fugitive particulates from haul roads/loaders, etc. and
why emissions have been accounted for in previous NOl's is presented in
Section 3.
Two hard copies of this NOi will go out in the mail tomorrow to your
attention.
If you have any questions, please feel free to contact MSI. I will be out
of the office next week but am available on my cell at 801-556-9188.
Sincerely,

1.0 INTRODUCTION
Meteorological Solutions Inc. (MSI) was retained by Harsco Metals to prepare a Notice
of Intent (NOi) to address proposed modifications to Harsco Metals slag processing operations at
the old Geneva Steel site in Vineyard, Utah. This NOi addresses the increase in emissions from
the addition of a 306 HP diesel engine and an 850 ton per hour rip rap plant. Harsco Metals
current Approval Order for slag processing operations at the old Geneva Steel plant is DAQE-
IN0107920001-08.
1.1 Facility Description
The Harsco Metals operation being performed at the old Geneva Steel site is located in
Utah County at 1500 North Geneva Road, Vineyard, Utah. The Universal Transverse Mercator
(UTM) coordinates in NAD 27 for the site are:
• 436,130 meters East
• 4,463,260 meters North
An aerial view of the site is presented in Figure 1.1. Figure 1.2 presents the site location
on a topographical map.
When these modifications are operational, operating hours for the rip rap plant and
generator will be limited to 3900 hours in any 12-month rolling period.

2.0 PROCESS DESCRIPTION
Harsco Metals operates a slag reprocessing facility at the old Geneva Steel plant site in
Vineyard, Utah. The slag reprocessing faci lity consists of an open hearth slag plant and blast
furnace slag plant ( consisting of crushers, screens, conveyor transfer points and diesel
generators). For this NOI, an 850 ton per hour rip rap plant equipped with a vibrating grizzly
feeder will screen products to stockpiles and a 306 HP diesel engine, which will provide the
power to the rip rap plant, are proposed. Figure 2.1 presents a process flow diagram for the rip
rap plant.

3.0 AIR EMISSIONS
Potential to emit (PTE) emission estimates were provided by Harsco Metals. Generator
emission estimates are based on manufacturer specific engine data and EPA guidance as
published in Compilation of Air Pollution Emission Factors, Volume I: Stationary Point and
Area Sources or AP-42 1 Section 3.3 Gasoline and Diesel Engines and proposed operating hours.
For the rip rap plant, emission estimates were based on AP-42 Section 11.19.2 Crushed Stone
Processing and Pulverized Mineral Processing and anticipated operating hours. Potential
controlled emissions for the rip rap plant and generator are presented in Table 3-1 and in
Appendix A. Engine specific data are also presented in Appendix A. PTE emissions are based
on a maximum of 3,900 operating hours in any 12-month rolling period.
Fugitive particulate estimates in the existing AO are based on 2,800,000 tons of material
throughput and 108,000 vehicle miles traveled (VMT) by the loaders/haul trucks and 80,889
VMT for the pot carriers. Due to no steel made and changes in raw material location, Harsco's
current operating scenario has resulted in only 1,400,000 tons of material processed and 77,000
VMT.
The proposed rip rap plant and associated operations will add 1,500,000 tons of material
processed and approximately 40,000 VMT to the current operating scenario. Total VMT for the
current and proposed operations is estimated to be 117,000 VMT which is well below the
188,889 VMT that emissions in the current approval order were based on.

Besides the inherent moisture of the material, application of water through use of a water
truck will be used as needed to minimize fugitive emissions.
For the generator, available control measures include proper engine maintenance,
combustion controls, and use of ultra-low sulfur fuel. No add-on pollution control equipment
such as selective catalytic reduction or catalytic oxidation systems is proposed.

4.0 BEST AVAILABLE CONTROL TECHNOLOGY
Per Utah Air Rules R307-400, best available control technology (BACT) is defined as an
emissions limitation (including a visible emissions standard) based on the maximum degree of
reduction for each air contaminant which would be emitted from any proposed stationary source
or modification which the executive secretary, on a case-by-case basis, taking into account
energy, environmental, and economic impacts and other costs, determines is achievable for such
source or modification through application of production processes or available methods,
systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion
techniques for control of such pollutant. BACT analyses for the emissions from the proposed
generator are discussed in the following sections.
4.1 BACT Analysis for Fugitive PM10 Sources
Screening and conveying of slag material creates fugitive PM10 emissions. The most
common control technology used to control fugitive PM10 is the application of water to maintain
moisture throughout the screening process. Wet scrubbers, cyclones, and ESPs are typically
eliminated from the BACT analysis because these emission control technologies are either
infeasible in a temperature variable outdoor environment, or because they are not considered
effective for total particulate control for screening operation. In most cases, baghouse control is
also eliminated from the BACT analysis before energy, economic, or environmental impacts are
addressed due to operational constraints and is cost prohibitive for screening operations. Thus,
the final options that would be available for BACT include:
• Inherent Moisture/No Additional Control; and
• Water Spray Control.
Harsco Metals 4-1 NOi
The Inherent Moisture/No Additional Control option was eliminated from the
technologies evaluated for BACT, as it could result in emissions of PM10 which may exceed
UDAQ fugitive opacity requirements. After removing those options that would be operationally
restrictive (wet scrubbers, cyclones, and ESPs), cost prohibitive options (baghouses) and the
options that would not provide adequate control (relying on inherent moisture of material), the
only BACT option is water application. Therefore, the application of water is defined as BACT
for the rip rap plant.
4.2 BACT Analysis for Generators
The proposed diesel-fired generator has the potential to create PM10, PM2.s, NOx, S02,
CO, VOCs, and HAPs emissions.
BACT for industrial engines of the sizes proposed has been established as good process
design and sound operating practices. Good process design includes proper and preventative
maintenance of the engines to ensure high efficiency of fuel combustion. Sound operating
practices for the engines involves using low sulfur-fuels and operating the engines only at the
load necessary.

The definitions and general requirements found in R307-I01 including R307-I01-3,
version of code of federal regulations incorporated by reference will apply to the Harsco Metals
proposed modifications.
Harsco Metals 5-1 NOi
5.2 R307-102 -General Requirements: Broadly Applicable Requirements
Emission of air contaminants in sufficient quantities to cause air pollution as defined in
R307-I01-2 is prohibited. The State statute provides for penalties up to $50,000/day for violation
of State statutes, regulations, rules or standards. In addition, the owner or operator of any
stationary air contaminant source in Utah shall furnish to the Board the periodic reports and any
other information as the Board may deem necessary to determine whether the source is in
compliance with Utah and Federal regulations and standards.
Any person submitting information pursuant to R307-102 may request that such
information be treated as a trade secret or on a confidential basis, in which case the Executive
Secretary and Board shall so treat such information. If no claim is made at the time of
submission, the executive secretary may make the information available to the public without
further notice.
5.3 R307-107 General Requirements: Unavoidable Breakdown
The unavoidable breakdown provisions ofR307-107 will apply to the Harsco Metals slag
reprocessing operation. A breakdown for any period longer than 2 hours will be reported to the
Executive Secretary within 3 hours of the beginning of the breakdown if reasonable, but in no
case longer than 18 hours after the beginning of the breakdown. Within 7 calendar days of the
beginning of any breakdown of longer than 2 hours, a written report shall be submitted to the
Executive Secretary which shall include the cause and nature of the event, estimated quantity of
pollutant (total and excess), time of emissions and steps taken to control the emissions and to
prevent recurrence.
5.4 R307-150 -Emission Inventories
Emission inventories will be submitted on or before ninety days following the effective
date of this rule and thereafter on or before April 15 of each year following the calendar year for
which an inventory is required.
Harsco Metals 5-2 NOi
-
Harsco Metals will submit an inventory every third year beginning with calendar year
2002 for all emissions units including fugitive emissions. The inventory will include PM10,
PM2_5, oxides of sulfur, oxides of nitrogen, carbon monoxide, volatile organic compounds,
ammonia, other chargeable pollutants, and hazardous air pollutants not exempted in R307-150-8.
For each pollutant, the inventory shall include the rate and period of emissions, excess or
breakdown emissions, startup and shut down emissions, the specific emissions unit which is the
source of the air pollution, composition of air contaminant, type and efficiency of the air
pollution control equipment, and other information necessary to quantify operation and
emissions and to evaluate pollution control efficiency. The emissions of a pollutant will be
calculated using the source's actual operating hours, production rates, and types of materials
processed, stored, or combusted during the inventoried time period.
5.5 R307-165 -Emission Testing
Emission testing is required at least once every five years of all sources with established
emission limitations specified in approval orders issued under R307-401.
5.6 R307-201 -Emission Standards: General Emission Standards
It is anticipated that the Harsco Metals operation will be subject to the visible emission
standards presented in R307-201. Emissions from the diesel engines, except locomotives,
manufactured after January 1, 1973 shall be of a shade or density no darker than 20% opacity,
except for station motion no farther than 100 yards or for stationary operation not exceeding
three minutes in any hour. Visible emissions exceeding the opacity standards for short time
periods as the result of initial warm up, start-up or shutdown of a facility, installation or
operation, or unavoidable combustion irregularities which do not exceed three minutes in length
shall not be deemed a violation provided that the Executive Secretary finds that adequate control
technology has been applied.
Harsco Metals 5-3 NOi
Harsco Metals shall minimize visible and non-visible emissions during start-up or
shutdown of a facility, installation, or operation through the use of adequate control technology
and proper procedures. Emissions shall be brought into compliance with these requirements by
reduction of the total weight of contaminants discharged per unit of time rather than by dilution
of emissions with clean air. EPA Method 9 will be utilized to determine opacity from stationary
sources.
5.7 R307-210 -Stationary Sources
The provisions of 40 Code of Federal Regulations (CFR) Part 60, effective on July 1,
2006, except for Subparts Cb, Cc, Cd, Ce, BBBB, DDDD, and HHHH, are incorporated by
reference. The New Source Performance Standards as found in 40 CFR Part 60 that Harsco
Metals will be subject to include Subpart A and Subpart IIII.
The provisions of 40 CFR Part 60 Subpart A applies to each affected facility as specified
in the relevant NSPS regulation for that source type. Subpart A contains general requirements
for notifications, monitoring, performance testing, reporting, recordkeeping, and operation and
maintenance provisions.
40 CFR Part 60 Subpart IIII, Standards of Performance for Stationary Compression
Ignition Internal Combustion Engines, will apply to the 306 HP diesel generator.
5.8 R307-305 -Nonattainment and Maintenance Areas for PM10: Emission Standards
This rule establishes emission standards and work practices for sources located in PM10
nonattainment and maintenance areas to meet the reasonably available control measures. This
includes visible emissions from existing installations except diesel engines shall be of a shade or
density no darker than 20% opacity. Visible emissions shall be measured using EPA Method 9.
Emissions from diesel engines, except locomotives, shall be of a shade or density no darker than
20% opacity, except for starting motion no farther than 100 yards or for stationary operation not
exceeding three minutes in any hour.
Harsco Metals 5-4 NOi
5.9 R307-309 -Nonattainment and Maintenance Areas for PM10: Fugitive Emissions
and Fugitive Dust
Fugitive emissions from any source shall not exceed 15% opacity. Opacity observations
of emissions from stationary sources shall be conducted in accordance with EPA Method 9.
Opacity caused by fugitive dust shall not exceed: (a) 10% at the property boundary; and (b) 20%
on site. Opacity shall not apply when the wind speed exceeds 25 miles per hour and the owner or
operator is taking appropriate actions to control fugitive dust. If the source has a fugitive dust
control plan approved by the executive secretary, control measures in the plan are considered
appropriate. Any person owning or operating a new or existing source of fugitive dust, including
storage, hauling or handling operations, or engaging in clearing or leveling of land one-quarter
acre or greater in size, earthmoving, excavation, or movement of trucks or construction
equipment over cleared land one-quarter acre or greater in size or access haul roads, or engaging
in demolition activities including razing homes, buildings or other structures shall submit a plan
to control fugitive dust to the executive secretary no later than 30 days after the source becomes
subject to R307-309.
5.10 R307-401 -Permit: New and Modified Sources
This rule establishes the application and permitting requirements for new installations
and modifications to existing installations throughout the State of Utah. According to R307-401
any person intending to make modifications or relocate an existing installation which will or
might reasonably be expected to increase the amount or change the effect of, or the character of,
air contaminants discharged, so that such installation may be expected to become a source or
indirect source of air pollution shall submit to the executive secretary a NOi and receive an
approval order prior to initiation of construction.
The NOi shall include the information described in R307-401-5 to determine whether the
proposed construction will be in accord with applicable requirements of these rules. Within 30
days after receipt of a NOi, or any additional information necessary to the review, the executive
secretary shall advise the applicant of any deficiency in the NOi or the information submitted.
Harsco Metals 5-5 NOi
6.0 OFFSET REQUIREMENTS AND EMISSION IMPACT ANALYSIS
New sources which have a potential to emit, or modified sources which are located in or
impact a PM10 nonattainment area and produce an emission increase equal to or exceeding the
tonnage total of combined PM 10, sulfur dioxide, and oxides of nitrogen are required to obtain an
enforceable offsets:
• For a total of 50 tons/year or greater, an offset of 1.2: 1 of the emission increase is
required.
• For a total of 25 tons/year but less than 50 tons/year, an offset of 1: 1 of the emission
increase is required.
For the offset determination, emission increases contained in the current December 2008
Approval Order (DAQE-IN0107920001-08) and proposed emission increases contained in this
NOI were reviewed since the emission increase requests have occurred within a two-year period.
For the offset determinations, PM10, sulfur dioxide (S02), and oxides of nitrogen (NOx) are
considered on an equal basis. For the proposed modification, the total of PM10, S02, and NOx
emissions was estimated to be 6.14 tons. The total PM10, S02, and NOx emissions, as listed in
DAQE-IN0107920001-08, are 18.76 tons (PM10 + 0.56, NOx+ 17.92, and S02 +0.28). Thus,
total emission increases of recently permitted emissions and proposed emission increases are
24.9 tons. This is below the offset threshold of 25 tons. In addition, the PTE emissions from the
proposed modification are below the criteria pollutant thresholds that are required to conduct a
dispersion modeling analysis.
Emissions of HAPS were calculated and HAP air quality analysis was conducted in
accordance with Utah Administrative Code R307-4I0-5. To determine which HAPs, if any,
required modeling, the UDAQ's 2007 ACGIH Threshold Limit Values (TL Vs), Toxic Screening
Levels (TSLs) and Emission Threshold Values (ETVs) spreadsheet was utilized. Based on the
methodology in R307-410-5, the emission rates of all HAPs were below the ETV levels; thus, no
dispersion modeling of HAPs was required.

METALS RECOVERY & SLAG PROCESSING. Harsco
Metals processes the remaining slag left from Geneva Steel's
Blast Furnaces and Q-BOP. Products include scrap iron, and
railroad ballast. Most scrap iron is now sold to Nucor Steel and
some steel processing centers.
Blast furnace and QBOP slag processing involves loading slag
into a feed hopper, which routes the material to screens and
crushers, and under magnets to removed metallic material.
Material that does not pass through the screen is often re-routed
through the crusher and screen, then conveyed and stored by
size. The only equipment remaining on site and operating is the
Rip Rap Plant and associated mobile generator. The Open-
Hearth Slag Plant and the Blast Furnace Slag Plant have been
demolished, and all associated equipment has been removed
from the site.
