Area Source Control Strategies 

The area source RACT analysis consisted of a thorough review of the entire area 

source inventory for anthropocentrically derived direct PM2.5 and precursors 

constituents. There was no emission threshold level established in the review process 

instead, the analysis centered on whether reasonable control measures are available 

for a given source category. The following table identifies these categories as well as 

the pollutant(s) likely to be controlled, and provides some remarks as to whether a 

control strategy was ultimately pursued. In considering what source categories might 

be considered, Utah made use of EPA recommendations (technical guidance’s known 

as CTG’s) as well as control strategies from other states. DAQ evaluated each strategy 

for technical feasibility as part of the RACT analysis. The screening column in the table 

identifies whether or not a strategy was retained for rulemaking or screened out for 

impracticability.

RACT Rulemaking Process 

EPA published Control Techniques Guidelines (CTGs) and Alternative Control 

Techniques documents (ACTs) for VOCs for a host of emission sources. The CTGs are 

used to presumptively define VOC RACT. The VOC ACTs describe available control 

techniques and their cost effectiveness, but do not define presumptive RACT levels as 

the CTGs do. Therefore, CTG’s are given highest priority in rule development. 

5.b.i - 2
Where a CTG does not exist for an emission source or where a CTG is so dated that it 

no longer represents current industry practice, we considered other state rules as 

reference sources. 

Additional reference sources include: the Ozone Transport Commission (OTC) and the 

Northeast States for Coordinated Air Use Management. 

Emission Reductions 

SIP rule credits are based on emission reductions for each rule. Emission reductions 

are calculated as follows: 

 Emission Reduction = [control efficiency (CE) x rule effectiveness (RE)] x rule 

 penetration (RP) 

Control Efficiency (CE) 

CE is a term that defines the expected emission reduction by implementing a rule. CE is 

normally derived from a CTG, however, some CTG’s did not provide emission reduction 

information that could be used to derive the CE or the data is dated. In cases where the 

CTG cannot be accurately referenced, we derive our CE’s from other sources, such as, 

the EPA database, AirControlNet and other state rulemaking background 

documentation. 

Rule Effectiveness (RE) 

RE is a term that describes a method to account for the reality that not all facilities 

covered by a rule are in compliance with the rule 100% of the time. RE also accounts 

for the fact that control equipment does not always operate at optimum control 

efficiency. EPA issued guidance on how to derive the RE value in a rule as part of an 

ozone and regional haze guidance document; Attachment 2: Non-Point Source Rule 

Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone and 

Particulate Matter National Ambient Air Quality Standards and Regional Haze 

Regulations, EPA 12/2005. This guidance document established three RE ranges for 

non-point sources: Range 1, 86-100%, Range 2, 70-85% and Range 3, less than 70%. 

Greatest emphasis is placed on historical enforcement within a given industrial sector 

thus Range 1 for example, requires that 90% of facilities inspected in the source 

category are in compliance. 

A review of compliance and complaint data showed that all source categories inspected 

by DAQ in the last five years are within Range 1. The following section provides 

supporting compliance data. 

Compliance Data Analysis 

All major sources receive a complete compliance inspection annually and all minor 

sources receive a complete compliance inspection every five years, as per the DAQEPA compliance agreement. Miscellaneous inspections occur while inspectors are in 

the field and by chance come across a suspected violation. Miscellaneous inspections 

are predominantly conducted of area sources that turn out to be deminimis issues. 

Warning letters are issued for minor infractions as a way to educate the regulated 

community. Compliance advisories are issued when an inspector suspects a violation 

has occurred that should be further investigated or require follow-up documentation 

from the source to resolve the issue. Settlements are resolved violations with fines. 

5.b.i - 3
Compliance of residential solid fuel burning on restricted days is addressed separately. 

The prevalent violations in 2009 were due to excess emissions from operations that 

occurred beyond permit constraints and failure to test. Failure to submit notice of intent 

to operate was the second most common violation. There were also higher numbers of 

opacity exceedances from equipment operations than in subsequent years. 

The predominant violation in 2010 was due to failure to file a notice of intent for 

installation of new equipment, modifications of equipment or transfer location of mobile 

equipment. One rare occurrence was noted for use of a non-complaint VOC based 

coating. 

Eight facilities failed to conduct testing under Subpart OOO, Standards of Performance 

for Nonmetallic Mineral Processing Plants, in 2011. Two facilities in 2009 and 2010 and 

four facilities in 2012 also failed to conduct that testing. 

The large numbers of violations in 2012 were related to operations in excess of their 

permit constraints. There were also some failures to conduct testing and a few stack 

test failures. 

Compliance History Related to Area Sources 

 The two open burning violations relate to the general burning rule R307-202. 

 The eight exceedance of fugitive dust opacity relate to R307-205 (attainment area) 

or R307-309 (nonattainment area), Fugitive Emissions and Fugitive Dust. 

 There were only 12 failures to maintain recordkeeping and only one of those was for 

an area source, which was an automotive shop. 

 The 50 emission exceedances are for major/minor sources which are not area 

sources.

 Only one non-complaint VOC based coating violation was noted that related back to 

the entire area source coating rules. 

 The remaining advisories are related to installation and/or transfer of equipment and 

permit exceedances that were not area source rule related. 

This compliance data verifies that a RE within Range 1 can be applied for most of the 

area source rules. 

RE Secondary Considerations 

EPA also included secondary considerations in their guidance in determining RE. 

Secondary considerations include: the level of detail applied during inspections, whether 

inspections are unannounced, frequency of inspections, enforcement authority and 

ability to issue fines, inspector training, source compliance testing (stack testing) and 

other associated considerations. 

Utah has an established delegated compliance program that incorporates all of the 

secondary considerations. The following provides examples of how the Utah 

compliance program meets or exceeds the secondary considerations in determining 

RE: 

 All major and minor sources are stack tested on 1-5 year frequency. 

 Permits conditions require O&M instructions on hand and we inspect to make sure 

they are present. 

 Unmanned and federal sites require advance inspection notice. Otherwise, all 

inspections are unannounced. 

 DAQ has the authority to impose punitive measures. 

 Major sources are inspected annually, at a minimum. Minor sources are inspected 

every five years. 

 EPA’s HPV policy was implemented when it was issued. 

 Permits include conditions that require operator training and recordkeeping. 

 Inspectors are trained in excess of the minimum two weeks suggested by EPA and 

updated as necessary. 

 Source testing schedules are maintained. 

 DAQ conducts follow-up inspections. 

RE Rating Rationale 

1. Since the DAQ compliance program meets or exceeds all secondary considerations 

established in the EPA guidance, we apply full credit for secondary considerations in 

all rulemaking, with no further discussion in the rulemaking of these secondary 

considerations. 

2. Where a current rule is already in place, we applied an RE within Range 1 based on 

meeting the primary compliance consideration and meeting all of the secondary 

consideration discussed above. 

 

3. An RE=80% was applied where a new rules is put in place and where an existing 

rule is being expanded in newly regulated counties. This value is based on EPA’s 

past default value used in previous SIPs as a conservative approach. 

5.b.i - 5
Rule Penetration (RP) 

“Rule penetration is an estimate of the percentage of emissions emitted by facilities 

covered by a regulation” (Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze 

Regulations, page 18, EPA 12/2005). 

Matrix 

RP = 100% where no threshold, apply to all 

RP = 98% for rule threshold of 2.7 tpy and when rule requires high efficiency add-on 

control 

RP = 95% for rule threshold of 5 - 10 tpy and construction related emissions 

Cost Effectiveness 

The RACT analysis includes cost consideration. Cost was derived from a CTG, the EPA 

database AirControlNet, or other information from other state rulemaking. Costs have 

been adjusted for the most current available market information - year 2011. 

Specific Rule Discussion 

R307-302. Solid Fuel Burning Devices in Box Elder, Cache, Davis, Salt Lake, Tooele, 

Utah and Weber counties. 

The wood burning restriction program in Davis, Salt Lake, Utah and Weber counties is a 

mature program, dating back to the early 1990’s with strong public and media support. 

The media provides wide broadcast of burning restrictions. Compliance is based on 

annual smoke complaints during red days which have steadily declined and DAQ 

smoke patrol of complaint areas. The smoke patrol will canvas an area for at least two 

hours to assure complete coverage. DAQ expects enhanced smoke patrol efficiency 

with the acquisition of a FLIR thermal imaging camera that will allow inspectors to direct 

a beam onto an exhaust stack/chimney from their vehicles. The FLIR camera can 

distinguish between water vapor from wood smoke where a home has a combined 

heater-stove exhaust. 

Cache County has a wood burning ordinance called Mandatory Restriction in Cache 

County on Use of Solid Fuel and Used Oil Burning Devices in place with strong public 

and media support. Their highest noncompliance has been 10-12 complaints/year. 

DAQ has noted a long history of 20-30 complaints per year for this major metropolitan 

area of Utah. A compliance analysis from 2009 demonstrated that even though the rule 

was newly applied in four counties in 2012, compliance based on complaint history, has 

been flat. 

DAQ conducted a modeling analysis in the 1997 to assess the level of compliance with 

the previous no burn action level of 120 μ/m3 PM10 in Utah County. That study 

concluded that control effectiveness was 83%, as measured in 1996. The actual 

effectiveness is expected to be greater than 83%, based on new PM2.5 woodburning 

5.b.i - 6
curtailment program requirements. R307-302 has been amended as part of this SIP to 

include a much lower no burn action level of 25 μg/m3 of PM2.5, with a contingency in 

the rule to lower it to 15 μg/m3. These lower action levels dramatically restricts the 

amount of burning that is allowed today in comparison to when the modeling study was 

conducted. At 15 μg/m3, wood burning would be prohibited for nearly the entire wood 

burning season. 

The use of wood as a heating source has declined since the 1990’s because 

economical natural gas is widely distributed throughout the Wasatch Front and because 

there are no hardwood forests in Utah. Quality wood must be trucked into the Wasatch 

Front. Gas fireplaces in new development are common in the Wasatch Front. 

The amended R307-302 also restricts sales of solid fuel devices to Phase II devices or 

EPA qualified fireplaces. DAQ also banned the sales of outdoor wood boilers in the 

Wasatch Front under a separate rule. 

DAQ applied a phase-in rule effectiveness schedule for all counties based on; 1) the 

high baseline compliance assessed in 1997, 2) the stringent rule amendments that will 

substantially reduce the number of burning days, 3) DAQs ability to enforce the rule with 

new monitoring instrumentation and 4) the reduction of wood burning already occurring 

in the Wasatch Front. The following phase-in schedule was applied: 

 2014 90%

 2017 92.5% 

 2019 95%

R307-303. Commercial Cooking 

DAQ applied a default RE of 80% for new rulemaking even though we expect that 

compliance will be higher. We base our belief on high compliance because DAQ is 

working with county health departments to draft county ordinances that would have food 

inspectors conduct compliance inspections of the ovens during their routine restaurant 

inspections. 

EPA staff requested information on the number of prospective ovens that apply to this 

rule and the frequency of inspections conducted by food inspectors per year. Most fast 

food restaurants prefer to use under-fire grills. Burger King is the predominant user of 

chain-driven charbroilers. There are a total of 41 Burger Kings in the PM2.5 

nonattainment counties as follows: 

Box Elder 1 

 Cache 2 

 Davis 4 

 Salt Lake 20

 Tooele 1 

 Utah 7 

 Weber 6 

According to the Salt Lake County Health Department web page, routine inspections 

“are typically unannounced and are completed 1 to 4 times per year depending on the 

establishment’s risk level (based on the complexity of food types, processes and meal 

volume).” Michele Cook, Food Safety Supervisor for the Weber-Morgan Health 

Department stated that Burger King is inspected twice a year. The Utah County Health 

5.b.i - 7
Department inspects all Burger Kings twice a year (personal communications with 

Division of Environmental Health). It would appear that health departments generally 

conduct multiple inspections a year. 

An advantage of applying catalytic technology to these ovens is that an inspector can 

determine compliance immediately by looking at the exhaust. There is no in between 

effectiveness, that is, the catalysts is either doing its job or it’s spent. None the less, we 

have included a 20% opacity limit in the rule. 

The high inspection rates by the health departments lead us to have a high comfort 

regarding compliance of this rule. 

R307-309. Fugitive Emissions and Fugitive Dust 

DAQ applied an RE of 80% for all counties because many counties and cities have 

fugitive dust ordnances and because nearly every one of the over 4,000 active permits 

contains a fugitive dust control requirement. 

The fugitive dust program has been in existence since the 1990’s. There are two rules, 

R307-309 is for the PM nonattainment counties and R307-205 is a statewide rule. 

R307-309 was amended in 2012 to add the PM2.5 counties and an entire new framework 

was created based on historical comments we have received from EPA on dust issues 

(both SIP and exceptional events). A departmental task force spent a year researching 

RACT for fugitive dust and compared other western state programs to ours. The task 

group than considered EPA’s comments in developing a set of recommendations to 

DAQ management that included: 

 Linking the fugitive dust plan submission to the online stormwater permit tool 

because these programs share a common regulated community that was more 

cognizant of the need to file stormwater permits than fugitive dust plans. 

 Restructuring the dust plan requirements based on best management practices 

(BMPs) that were defined during the research phase of the project. The task group 

spent another year drilling down the details for each BMP, than programmed the 

BMPs into the online stormwater-fugitive dust tool. The result has been an 

exponential growth in fugitive dust plan filings. 

DAQ receives a number of dust complaints each year. Overall, the number of dust 

complaints has significantly decreased since 2008. Very few complaints are actually 

due to an exceedance of the standards. There were only eight violations from 2009 to 

2012 out of 2,126 inspections. Compliance history for this rule exceeds 99%. This data 

suggests that the RE should actually be raised in the SIP. 

R307-312. Aggregate Processing Operations for PM2.5 Nonattainment Areas 

R307-312 establishes emission standards for sources in the aggregate processing 

industry, including aggregate processing equipment, hot mix asphalt plants, and 

concrete batch plants. We applied a default RE of 80% for new rulemaking even though 

there is evidence that compliance is near 100% for at least the opacity limit in the rule. 

According to EPA, most facilities already comply with the opacity limits in the rule (FR 

Vol 74, Issue 80, April 28, 2009, page 19300). We reviewed the 186 compliance 

advisories for the last four years. We found eight facilities that had not conducted their 

5.b.i - 8
opacity testing under Subpart OOO and were required to do so. No facility failed to meet 

the standard. There were no violations issued to these facilities regarding the opacity 

standard in the rule. 

The second part of the rule requires asphalt plants to switch fuel sources in the winter. 

Facilities have been doing so before the rule because of the economic incentive. 

We believe that the 80% RE applied in the SIP is overly conservative. 

R307-335. Degreasing and Solvent Cleaning Operations 

This rule is divided into two sections, the first is the tank degreasing portion that has its 

roots in the 1994 degreasing MACT and the second portion is the new section, R307-

335-7. Industrial Solvent Cleaning, which is based on that EPA Control Techniques 

Guidelines document. 

According to EPA comments of July 2, 2012, enforcement records show there are only 

six tank sources located within Salt Lake, Utah, Weber, Summit and Box Elder counties. 

DAQ reviewed the 186 compliance advisories for the four years and could only find one 

violation in 2009 in Salt Lake County for improper tank cover management. Given the 

small number of sources and one violation, we concluded there is a high compliance 

rate which would be higher than the 80% that was used in the SIP. 

R307-335-7 is a new section that has already resulted in numerous inquiries for DAQ 

support in meeting the rule. Some sources initially had difficulty finding commercial 

available solvents that meet the VOC and/or vapor pressure standards recommended in 

the EPA CTG. Consequently, this section of the rule has been amended in 2013 and 

2014 to address the shortcomings of the CTG recommendation. 

DAQ applied an RE of 80% for this portion of the rule based on DAQ’s in-depth 

knowledge of source operations where this portion of the rule applies. 

Surface Coating Rules 

R307-340 was the original surface coatings rule that incorporated all of the coating 

categories. That rule was over 20 years old when it was repealed in 2012 and replaced 

with individual rules for each coating category. Each new coating rule was also updated 

to the most current RACT standard. These rules include: 

R307-344. Paper, Film & Foil Coating 

R307-345. Fabric & Vinyl Coating 

R307-346. Metal Furniture Surface Coating 

R307-347. Large Appliance Surface Coating 

R307-348. Magnet Wire Coating 

R307-349. Flat Wood Panel Coating 

R307-350, Miscellaneous Metal Parts & Products Coating 

R307-351. Graphic Arts 

R307-352. Metal Containers, Closure & Coil Coating 

R307-343. Wood Manufacturing remained a stand-alone surface coating rule. This rule 

was also amended to the most current RACT standard. 

Only one violation of the 186 compliance advisories for the last four years was 

associated with all of these rules. The violation was for excess temperature setting on a 

5.b.i - 9
catalyst at a printing facility. REs of 80% for newly regulated counties and an RE of 90% 

for those counties where the rules have been in place since the 1990’s were applied. 

The compliance history supports the RE selections. 

New Surface Coating Rules 

The following are new surface coating rules that become effective in all of the 

nonattainment counties. 

R307-353. Plastic Parts Coating – Plastic parts coating, like graphic arts, occur in a 

wide variety of commercial and industrial settings. In fact, it is so widely spread, that 

EPA was not able to conduct a complete assessment of its use for the miscellaneous 

metal and plastic parts coating CTG (personal communications with Kim Tea, EPA). 

This is important to note because we are bound to come across plastic coating 

operations in diverse settings during inspections. While DAQ did not regulate this 

activity in the past, inquiries were made of our compliance personnel to find out if they 

had come across any suspect activities which they can now pursue. We were not able 

to identify any facility which we would investigate specifically for this new rule. Given the 

diverse use of plastic coating and our knowledge that there are no outstanding facilities 

to pursue, a RE of 80% is warranted. 

R307-354. Automotive Refinishing – While this is a new rule, DAQ has been inspecting 

automotive refinishing facilities that have permits. A review of the last four years of 

compliance advisories indicates that there was one violation cited for failure to maintain 

records at an auto body facility. DAQ applied a RE of 80% for this rule because the rule 

applicability is at 2.7 tpy, which is below our permit threshold of 5 tpy. 

R307-355. Control of Emissions from Aerospace Manufacture & Rework Facilities – 

DAQ worked closely with the aerospace industry on this rule development because of 

the rule complexity and the existence of a MACT on which these facilities have based 

their business model. Boeing advised DAQ that most aerospace facilities are already 

complying with this rule because it is very similar to the MACT. Therefore, we believe 

that a RE of at least 80% is warranted. 

Other New Rules 

These new rules are based on national product development programs with REs at 

100%, consistent with use by other states and substantiated in many instances by 

Pechan (AirControlNET, 2006). 

R307-342. Adhesives & Sealants 

R307-356. Appliance Pilot Light 

R307-357. Consumer Products

Discussion 

The wood burning restriction program in Davis, Salt Lake, Utah and Weber counties is a 

mature program, dating back to the early 1990’s with strong public and media support. 

The media provides wide broadcast of burning restrictions. Compliance is based on 

annual smoke complaints during red days which have steadily declined and DAQ 

smoke patrol of complaint areas. The smoke patrol will canvas an area for at least two 

hours to assure complete coverage. DAQ expects enhanced smoke patrol efficiency 

with the acquisition of a FLIR thermal imaging camera that will allow inspectors to direct 

a beam onto an exhaust stack/chimney from their vehicles. The FLIR camera can 

distinguish between water vapor from wood smoke where a home has a combined 

heater-stove exhaust. 

5.b.i - 11
Cache County has a wood burning ordinance called Mandatory Restriction in Cache 

County on Use of Solid Fuel and Used Oil Burning Devices in place with strong public 

and media support. Their highest noncompliance has been 10-12 complaints/year. 

DAQ has noted a long history of 20-30 complaints per year for this major metropolitan 

area of Utah. A compliance analysis from 2009 demonstrated that even though the rule 

was newly applied in four counties in 2012, compliance has been flat. 

DAQ conducted a modeling analysis in the 1990’s to assess the level of compliance 

with the previous no burn action level of 120 μ/m3 PM10 in Utah County. The following is 

an excerpt of that study. 

The highest PM10 concentrations in Utah County over the past few years occurred during a 1996 

episode, where concentrations approached the 24-hour NAAQS. Speciated PM10 data were 

analyzed from the Lindon monitor for this period. A Chemical Mass Balance (CMB) model source 

apportionment analysis of this episode was performed to identify the amount of contribution from 

the various sources that were originally identified in the 1989 design day CMB source 

apportionment. This episode represents the highest measured PM10 concentration in Utah 

County since the projected 1993 attainment date, when all control strategies were to be in place. 

Source contributions estimated by the CMB model during this episode can be used to evaluate 

the effectiveness of the controls placed on them. In particular, a comparison of the amount of 

reduction in wood burning impacts due to the wood burning curtailment program was performed 

using the CMB model results. 

The following table represents the source contributions during the 1996 episode. As this table 

indicates, the amount of wood burning impacts have dropped considerably since the design day 

in 1989.

Secondary Nitrate 36.80

Road Salting 2.11

Unaccounted 29.97

Total Measured 147.00

The amount of wood burning impact reduction from the design day, measured on February 18, 

1989, to the highest measured day in 1996 is calculated. On this design day, the CMB model 

estimated a wood burning impact of 42.7 μg/m3. As the above table indicates, on the highest day 

measured in 1996, the CMB model estimated a wood burning impact of 7.12 μg/m3. The amount 

of reduction from 42.7 μg/m3in 1989 to 7.1 μg/m3in 1996, equates to a 83% reduction. This 

represents the amount of reduction in wood burning that actually occurred during the highest 

5.b.i - 12
PM10 concentrations days from 1989 to 1996. Since the PM10 concentrations in the 1996 

episode were above the 120 μg/m3level, a wood burning ban was in affect. Thus, the 83% 

reduction is a good indicator of the effectiveness of the wood burning curtailment program used in 

Utah County. 

Additional PM2.5 Related Woodburning Control Requirements 

In 1997, a PM 2.5 NAAQS was established and Subsection R307-302-2, UACR was amended to 

include a woodburning ban when ambient concentration of PM2.5 reached levels of 52 μg/m3 as 

measured by the real-time monitor located at the Lindon monitoring site. This new additional 

woodburning restriction, based on measured PM2.5 concentrations, in affect lowers the 

concentration level that triggers the woodburning ban. Previous winter monitoring data indicated 

that when the PM2.5 levels reached 52 μg/m3, the PM10 concentrations were in the 60 to 80 

μg/m3 range. This lower PM10 level, under which a woodburning curtailment is required by law, 

further reduces the amount of woodburning emissions that will occur from levels experienced in 

1996. Therefore, because of the new PM2.5 restrictions, the control effectiveness of the 

woodburning curtailment program is expected to be better than 83%, as measured in 1996. 

Conclusion 

In conclusion, the control effectiveness of the woodburning curtailment program is calculated to 

reduce the 1989 design day impacts from woodburning by at least 83%. As indicated above, the 

actual effectiveness is expected to be greater than 83%, based on new PM 2.5 woodburning 

curtailment program requirements. 

DAQ applied a phase-in rule effectiveness schedule for all counties based on; 1) the 

high baseline compliance assessed in 1997, 2) the stringent rule amendments that will 

substantially reduce the number of burning days, 3) DAQs ability to enforce the rule with 

new monitoring instrumentation and 4) the reduction of wood burning already occurring 

in the Wasatch Front. The following phase-in schedule was applied: 

 2014 90%

 2017 92.5% 

 2019 95%

SUBJECT: FINAL ADOPTION: R307-302. Solid Fuel Burning Devices in Box Elder, Cache, Davis, 

Salt Lake, Tooele, Utah, and Weber Counties; and R307-207. Residential Fireplaces and 

Solid Fuel Burning Devices.

______________________________________________________________________________________ 

The Board approved for public comment the amendments to the two residential fireplace and stove rules as 

part of the State Implementation Plan (SIP) for PM2.5. R307-207 applies to attainment areas while R307-

302 applies to nonattainment and maintenance areas. 

The title of each rule has been revised to include all solid fuel burning devices. This change permits us to 

regulate residential coal burning. This is the predominate change made to R307-207. 

Revisions to R307-302: 

1. The applicability has been redefined to include the entire PM10 and PM2.5 areas. 

2. The sole source registry will be re-opened because the expansion of the rule applicability. 

3. The red-alert cut point for PM2.5 has been reduced from 35 to 25 micrograms per cubic meter. A 

contingency plan cut-point of 15 micrograms per cubic meter has been added for PM2.5.

4. Sale and distribution of non-EPA certified/qualified stoves is prohibited. Existing non-EPA 

certified/qualified stove units may remain in a residential dwelling as part of a real estate 

transaction, so long as the unit remains intact within the real property for sale. 

The public comment period was held from September 1 to October 1, 2012. Two individuals and one civic 

organization submitted comments supporting the proposal for R307-302.

A public hearing was held on September 12, 2012. Two individuals representing their neighborhood 

submitted a petition against R307-302, but that petition was based on a misunderstanding of the rule by the 

parties. They incorrectly believed that the proposed rule would prohibit their ability to continue using their 

current wood stoves. 

Staff Recommendation: Staff recommends the Board approve R307-207 as proposed and R307-302 as 

amended.

DAQ applied a default RE of 80% for new rulemaking even though we expect that 

compliance will be higher. We base our belief on high compliance because DAQ is 

working with county health departments to draft county ordinances that would have food 

inspectors conduct compliance inspections of the ovens during their routine restaurant 

inspections. 

RACT Analysis Summary 

There are no EPA guidance documents for this emission source. The analysis was 

based on review of the Bay Area Air Quality Management District and the San Joaquin 

Valley Air Pollution District RACT analyses and the City of Aspen rule. Direct contact 

with staff at these three air districts were made to gain actual implementation and frontline performance information and cost, including operational and maintenance cost 

(O&M). 

Emissions from under-fire charbroiling are substantial and are not covered under R307-

303. Unfortunately, current technological options are limited and overly expensive. The 

California air districts that have rules in place require installation of a water scrubber or 

electronic precipitator for restaurants that charbroil very large amounts of meat per 

5.b.i - 19
week using under-fire units that are ten square feet in size. The City of Aspen requires a 

specific water scrubber which only one restaurant has been able to install at this time. 

These add-on controls have a low efficiency and their cost for this application is around 

$15,000/ton of pollutant removal. The City of Aspen restaurant spends $5,000/quarter 

on O&M for that unit. UDAQ is tracking the progress of innovative technology 

demonstrations for future rulemaking consideration. These include: 

 The South Coast Air Quality Management District has partnered with the 

University of California Riverside to test control technologies. One promising 

technology is manufactured by FMI Products. FMI has submitted an under-fire 

hood installed heated catalysts for testing. 

 EPA contracted with Innova Tech to develop a low cost, low O&M under-fire 

charbroiling filtration device.

SUBJECT: FINAL ADOPTION: R307-303. Commercial Cooking. 

______________________________________________________________________________________ 

On July 11, 2012, the Board proposed for public comment R307-303, which established a control limit of 

at least 80% reduction for PM2.5 and volatile organic compounds using catalytic oxidation on chain-driven 

charbroilers used in food service establishments. 

The public comment period was held from August 1 to August 31, 2012. No comments were received. A 

public hearing was held on August 15, 2012. No one appeared at the hearing. 

Staff made sure that key stakeholders were given advance notice of rulemaking. The Utah Restaurant 

Association was sent an advance copy of the proposed rule. Corporate Burger King was contacted by 

telephone to advise them of the rulemaking. 

EPA submitted written comments on September 19, 2012, to which staff responded to in the Board memo 

of December 5, 2012. 

During the December Board meeting, the Board directed staff to revise the rule to require a control limit of 

75% and to release that revision for public comment. The Board was concerned that no vendor would 

certify a catalyst with a control efficiency at 80%. The public comment period was held from December 1 

to December 31, 2012. No comments were received. 

Even though vendors may not certify a catalyst with a control efficiency of 

80%, we are confident that the catalysts would perform at above 90% 

efficiency. On a chain-driven charbroiler, meat is placed onto the chaindriven platform at the entry point, travels under the grill and exits at the other 

end. The entry and exit points are sources of fugitive emissions. It is 

Entry 

 Exit 

5.b.i - 21
DAQ-007-13 

Page 2 

estimated that 10% of the emissions are lost through these points. In other words, about 90% of the 

emissions flow by the catalyst. The manufacturers do not want to be accountable for fugitive losses. 

We also know from the Bay Area Air Quality Management District’s experience with these catalysts that 

they work immediately upon being installed and heated. In other words, an opacity reading is all that is 

necessary to determine if one is installed and operating correctly. Therefore, to resolve the Boards 

concern, we have amended the rule by removing the efficiency requirement. 

SIP Credit 

Emission reductions are calculated as follows: 

Emission Reduction = [control efficiency (CE) x rule effectiveness (RE)] x rule penetration (RP) 

CE is a term that defines the expected emission reduction by implementing a rule. In this case, the CE is 

the expected efficiency of the catalysts. The efficiency of this type of catalysts is 90-95%. For this case, 

we assume a conservative value of 90%. 

RE is a term that describes a method to account for the reality that not all facilities covered by a rule are in 

compliance with the rule 100% of the time. We normally apply an RE of 80% for new rulemaking. 

RP is an estimate of the percentage of emissions emitted by facilities covered by a regulation. We are 

applying an RP of 100% based on the matrix defined in the SIP when a rule applies to all 

applicable units/facilities. 

Emission Reduction = [90% x 80%] x 100% = 72% SIP reduction for chain-driven charbroiling 

Staff Recommendation: Staff recommends the Board adopt R307-303, Commercial Cooking, as amended.

conducted as part of that SIP. The rule was amended by expanding the applicability to 

include PM2.5 nonattainment areas. The road salt criteria in the rule were not modified 

therefore, no new RACT analysis was necessary.

SUBJECT: FINAL ADOPTION: R307-307. Road Salting and Sanding. 

______________________________________________________________________________________ 

On September 5, 2012, as part of the PM2.5 state implementation plan, the Board proposed for public 

comment amendments to R307-307. The proposed changes expanded the applicability of R307-307 to 

include the entire PM2.5 nonattainment area. The new areas added to this rule would be required to be in 

compliance by January 1, 2014. 

A public comment period was held from October 1 to November 1, 2012, and there were public hearings 

held on October 15, 16 and 17. During the public comment period, we received comments from the Utah 

Department of Transportation (UDOT) and EPA. We are making several recommended changes to the 

proposed rule based on these comments. 

UDOT Comments 

1. In the interest of public safety, UDOT needs to apply grit material to certain segments of roadway that 

are within the nonattainment areas. UDOT submitted a list of roadway segments that they specifically 

requested be exempt from the requirements of R307-307-4(1). 

DAQ Response: We agree that in the interest of public safety these roadways should be exempt from 

these requirements. The rule has been changed to reflect this. 

2. The rule should use a word like “abrasives” instead of “sand” as there are several types of abrasives 

other than sand that are used on the roads. 

DAQ Response: We agree and have changed language throughout the rule to clarify that the rule 

applies to sand and other abrasives.

EPA Comments 

1. Section R307-307-1 was revised to provide boundaries based on geological landmarks. This section 

needs to be changed to specify that the boundary is for all PM2.5 nonattainment areas by incorporating 

by reference 40 CFR 81.345. 

DAQ Response: Section R307-307-1 is changed to incorporate by reference the July 1, 2011, version 

of 40 CFR 81.345. 

2. The provision of R307-307-4 should be revised to include PM2.5 emissions. 

DAQ Response: Language has been added to include PM2.5 emissions. 

3. The rule contains apparent director’s discretion provisions which cannot be approved by the EPA. 

DAQ Response: We have removed the director discretion language. 

Staff Recommendation: Staff recommends R307-307 be adopted as amended.

Discussion 

The fugitive dust program has been in existence since the 1990’s. R307-309 was 

amended in 2012 to add the PM2.5 counties and an entire new framework was created 

based on historical comments we have received from EPA on dust issues (both SIP and 

exceptional events). A departmental task force spent a year researching RACT for 

fugitive dust and compared other western state programs to Utah’s. The RACT analysis 

also included a review of the WRAP Fugitive Dust Handbook and internal engineering 

and inspectors insights. The following table provides a summary of our analysis.

 South Coast, Washoe, Clark and Maricopa Counties have stringent opacity requirements ranging from no visible dust at 

property boundary, no visible dust any time, to limiting visible dust to five minutes within an hour. Impetus: serious 

nonattainment. 

 Washoe, Clark and Maricopa Counties have more stringent high wind requirements. Generally speaking, they include the 

option to cease operations or institute contingency measures. Impetus: serious nonattainment. 

The outcome of that analysis was: 

o Utah’s rule is generally more stringent than most based on the 1⁄4 acre 

applicability. 

o The high wind provision in R307-309 was being miss-interpreted by EPA and 

to some extent, the regulated community. 

o More stringent requirements for emission management under high wind 

conditions are necessary. 

o Control measures in R307-309 are suggested but not required. 

The task group provided the following recommendations: 

1. Re-word the high wind provision in R307-309 so that it is clear that sources 

must continue to implement control measures. 

2. Require a high wind contingency plan. 

3. Removed 30-day dust plan filing window. 

4. Require that dust generating activities may not commence before obtaining 

approved dust plan. 

5. Develop best management practices (BMPs) for all dust source categories. 

6. Replace the suggested control measures language in R307-309 with 

requirement to implement BMPs. 

7. Create a one-stop shop for a stormwater permit and fugitive dust control plan 

filing. Offer an online tool using a regulatory decision logic that will guide the 

applicant through the process. A correctly completed application results in an 

instant online fugitive dust plan. 

All of the task force recommendations were incorporated into the amended rule.

DAQ receives a number of dust complaints each year. Overall, the number of dust 

complaints has significantly decreased since 2008. Very few complaints are actually 

due to an exceedance of the standards. There were only eight violations from 2009 to 

2012 out of 2,126 inspections. Compliance history for this rule exceeds 99%. This data 

suggests that the RE’s should actually be higher than the credits taken in the SIP.

DATE: October 25, 2012 

SUBJECT: FINAL ADOPTION: R307-309. Nonattainment and Maintenance Areas for PM10 and 

PM2.5: Fugitive Emissions and Fugitive Dust. 

______________________________________________________________________________________ 

On July 11, 2012, the Board proposed for public comment amendments to R307-309. The proposed 

amendments to the rule included expanding the rule applicability to the PM2.5 nonattainment counties, 

clarifying that EPA Method 9 is used to measure opacity, requiring sources to comply with their fugitive 

dust plans when winds exceed 25 miles per hour, adding high-wind contingency measures, and requiring 

sources to submit a fugitive dust control plan before commencing activities. 

The public comment period for this proposal was from August 1 to August 31, 2012, and received 

comments from industry and environmental associations. A public hearing was held on August 15, 2012, 

and representatives from an aggregate operation provided written and verbal statements. 

The following is a summary of the major public comments specific to this rulemaking and DAQ’s 

corresponding responses: 

1. The rule should only apply to the defined nonattainment areas. 

Response: We concur, and have amended the applicability to be only those areas within the 

nonattainment area boundaries. 

2. Existing fugitive dust control plans approved under AO’s should be recognized as meeting the 

requirements under the amended rule. 

Response: We concur, and have amended the rule to state that dust control plans submitted before 

December 3, 2012, will have met the filing requirement. This is intended to clarify that existing plans 

are not subject to re-filing. 

5.b.i - 33
DAQ-093-12

Page 2 

We received separate comments from industry and EPA related to this issue, i.e., that mining, tailings 

and ponds are more complex projects than those predominately addressed under R307-309-6. The 

1992 rule approved by EPA had separate fugitive dust plan filing requirements for these sources than 

from general construction. We agree with commenters that these sources should be separately 

addressed in greater detail as has historically been the case. We have amended the rule to require more 

detailed fugitive dust control plans for these sources. 

3. The 30-day compliance schedule for newly regulated areas is insufficient time.

Response: We concur with this comment for Sections R307-309-10 and 11, and have extended the 30-

day compliance schedule for newly regulated sources to 90 days for those sections only. However, 30 

days is sufficient time for new sources to be in compliance with all other requirements of the rule. 

4. The 1⁄4 acre applicability should be increased to 5 or more acres. 

Response: The 1⁄4 acre applicability has its roots in EPA’s emission factor analysis for dust from 

construction. This applicability also exists in our current statewide rule for construction, R307-205. 

Therefore, we are not proposing any changes for either R307-309 or R307-205. 

5. The rule should allow the use of the nearest meteorological station to determine wind speed. 

Response: Wasatch Front meteorological conditions are complex and subject to localized effects that 

would not be captured by regional meteorological stations. 

6. Modify the requirement for “hourly” watering to “frequent” watering during high wind events. 

Response: We believe that a requirement for “hourly” watering is more definitive and easier to monitor 

for compliance. 

7. Fugitive emissions should be measured prior to emission control. 

Response: We do not concur, because by definition, fugitive emissions cannot be routed through a 

stack vent, making this technically challenging. 

8. Opacity measurements for fugitive emissions should be “above the source at a point equal to the height 

of the emission source or 20 feet, whichever is greater.” 

Response: We measure fugitive emissions using EPA’s Method 9. 

9. It is not appropriate to use EPA’s Method 9 averaging periods for measuring emissions from moving 

vehicles. 

Response: We apply a modified Method 9 without averaging periods. 

10. Dust control on roads should be limited to non-public unpaved roads. 

Response: Road is defined in R307-101-2 as “any public or private road.” Industrial sources use both 

public and private roads, and in the event that they create fugitive dust emissions, they are accountable, 

regardless of the type of road where the emissions are created. 

11. It is not clear whether an approval process exists for the fugitive dust control plan. 

Response: We agree, and have amended the rule accordingly in R307-309-6(2). 

12. Fugitive dust could be included in definition of fugitive emission; thereby, fugitive dust could be 

subject to opacity limits for fugitive emissions. 

Response: The definitions for fugitive dust and fugitive emissions in R307-101-2 are clearly distinct. 

Fugitive dust is not a part of fugitive emissions. 

5.b.i - 34
DAQ-093-12

Page 3 

13. The requirement for pre-event contingencies for high wind events should include the option for an 

alternate control measure other than those identified in the rule. 

Response: We concur, and have amended the rule to allow an alternate measure approved by the 

Director.

14. The rule merely suggests control measures. 

Response: Regrettably, we did not include a hard copy of the online tool as part of the public comment 

documents which would have shown that the rule requires the use of specific best management 

practices. 

15. The rule lacks record keeping requirement(s). 

Response: We concur, and have amended the rule to include record keeping requirements. 

16. The rule should include monitoring methods. (An extensive description was provided.) 

Response: We do not concur because the detailed recommendations are impractical when dealing with 

fugitive dust. 

17. The opacity limits are not reasonably available control measure (RACM) or reasonable available 

control technology (RACT). The following recommendation is an option taken from the Western 

Regional Air Partnership (WRAP) dust handbook that should be used for RACM or RACT: 

“Prohibit visible dust emissions beyond property line and limit an upwind/downwind PM10 

differential to 50μg/m3

. Limit visible dust emissions to 100 feet from origin.” 

Response: Various chapters in the WRAP handbook provide example control limits employed by 

jurisdictions. The commenter proposed limit comes from the South Coast Air Quality Management 

District (SCAQMD) Rule 403. SCAQMD has made a determination that this limit is best available 

control measures (BACM) for SCAQMD. However, RACT/BACM determination should be made 

based on Utah-specific conditions. The WRAP handbook states that “the handbook is not intended to 

suggest any preferred method to be used...but rather to outline the most commonly adopted 

methodologies...” The opacity limit used by DAQ is included in the same citations as the limit 

proposed by the commenter. We believe that the commenter’s proposed limit is not reasonable 

because of the many implementation problems it poses, and therefore is not RACT. Our specific 

concerns are: 

a. How would one determine compliance with the 50μg/m3

 differential when fugitive dust cannot 

be directly measured from a source? 

b. Assuming PM10 is used as an indicator, would each fugitive dust source be required to 

purchase and place upwind and downwind real time monitors? Most fugitive dust sources are 

minor sources (rule applicability - 1⁄4 acre). 

c. How would the DAQ determine property boundary under field conditions during compliance 

inspections? 

d. How would DAQ compliance staff enforce the 100 feet limit, especially under open traffic 

conditions which could be hazardous? 

We have made a determination that the current opacity limit is RACT for Utah and do not believe the 

commenter’s proposal would be beneficial because it cannot be implemented.

EPA Comments: 

EPA submitted written comments stating that the rule cannot be approved without incorporating the 

fugitive dust control plan best management practices presently contained in the online tool, thereby making 

those requirements enforceable. This amendment required a format change to R307-309-6. 

EPA pointed out that the last version of the rule approved by EPA was R307-1-4.05 effective in 1992 and 

that subsequent rule amendments have not been approved by EPA. EPA believes that removing certain 

requirements pertaining to traffic volume on unpaved roads and the high wind exemption are relaxation of 

the regulation. Therefore, EPA is requesting that we conduct a 110(l) demonstration to prove that there has 

not been rule backsliding. We developed the required 110(l) demonstration and it was posted to the Utah

Bulletin for public comment from November 1 to December 3, 2012. The 110(l) demonstration and R307-

1-4.05 are attached.

Traffic Volume 

Control measures for unpaved roads based on the number of vehicle trips per day were established in the 

rule as part of the Total Suspended Particulate plan in 1982. The application of the rule focused on 

industrial roads, such as haul roads, within the limited nonattainment boundary that existed at that time. 

When the PM10 nonattainment area was designated, the entire Salt Lake County became nonattainment and 

the shift was made to secondary formation of PM10 during wintertime inversions. Unpaved roads are not a 

significant contributor to PM10 during inversions. DAQ staff and metropolitan planners determined that 

there were not many unpaved roads left, and those that were left were subject to permitting and Best 

Available Control Technology requirements, as well as the fugitive dust plan requirements in the rule.

Therefore, the provisions of the rule dealing with traffic volume were removed. 

High Wind Exemption 

It is well recognized that there are location-specific wind speed thresholds that, once attained, make dust 

control measures less to non- effective. EPA is currently proposing a uniform wind threshold of 25 mph 

for exceptional events, with the option for states to submit data supporting a lower threshold. Recognizing 

this practical/technical limitation, we included a waiver from meeting the opacity requirements in R307-

309-5 when wind speed exceeds 25 mph. This waiver from the opacity standard has caused missinterpretation by EPA. EPA believes that we are exempting sources from the rule during high winds. We 

have had numerous discussions with EPA on this issue in order to resolve this misinterpretation; 

nonetheless, this issue remains unresolved. Therefore, we have reinforced the rule to add language that 

clearly explains the opacity waiver is effective only if 1) the source continues to implement accepted 

control measures during high winds, and 2) a high wind contingency plan has been implemented. If a 

source does not meet the requirements of 1) and 2), the opacity limits in the rule and permit conditions 

apply and will be enforced. 

The following are EPA’s other substantive comments: 

1. The rule does not include enforceable conditions where sections of the rule states that controls “may 

include.” 

Response: The words “may include” in Sections 10 and 11 have been changed to “must” and the 

associated control measures have been reworded so that sources understand that they must make a 

selection where options are provided. 

5.b.i - 36
DAQ-093-12

Page 5 

2. The rule does not state that sources must comply with all sections of the rules at all times.

Response: This is a fundamental requirement of any regulation. It is not necessary to state the obvious 

unless there are specific conditions that warrant detailed discussion; therefore, we have determined that 

no change is necessary. 

3. It is not clear if a new fugitive dust control plan is required when sources make modifications. 

Response: We agree, and have added a clarification to R307-309-6(3). 

4. What happens when a source is not required to have a storm water permit? How does that work with 

the online tool? 

Response: The tool has a decision matrix that determines a source regulatory requirement(s) and acts 

accordingly. 

5. Agriculturally-derived dust other than from burning is not exempt. How do we enforce agricultural 

compliance with the rule? 

Response: We agree, and have revised the exemption in R307-309-3 to exempt all agricultural 

activities, consistent with the exemption in the EPA-approved version of the rule dated 1992. 

6. Fugitive dust plans must be approved, and not just accepted. 

Response: We agree, and have amended R307-309-6(2) accordingly. 

7. Why is road salting exempt from the rule? 

Response: Fugitive dust is not generated by road salting during a winter storm. After a storm event, 

the materials are either dissolved or deposited (depending on chemical/physical composition) on 

roadway shoulders or swept into storm drains. Filter speciation data shows that road salting 

contributes less than 1% of PM2.5 and much less of PM10 on average. Other rules (R307-307) require 

that salt applied to roadways be at least 92% pure salt. Further, it is not feasible to expect highway 

personnel to sweep or wash every inch of roadway after each and every salting. 

8. EPA questions the opacity measurement method for mobile sources.

Response: EPA Method 9 is not intended to measure opacity for mobile sources. In the absence of an 

EPA method, we developed a reasonable method over 25 years ago. 

9. The rule does not have any test methods, recordkeeping, or reporting requirements to make the rule 

enforceable.

Response: We agree, and have added recordkeeping requirements. We specify test methods for 

fugitive emissions and stationary sources as EPA Method 9 and a practical method for mobile sources. 

We do not require reporting from any area source rule, but rather rely on EPA’s requirement for a triannual emissions inventory report. 

Staff Recommendation: Staff recommends the Board approve R307-309 as amended.

Geneva Rock Products 

Point of the Mountain Facility

(Hansen-Lehi Pit and Mount Jordan Pit) 

Site ID:

10565 & 12776 

Description of Facility: 

The Geneva Rock Products Point of the Mountain Facility is an aggregate processing facility 

that consists of the Hansen-Lehi Pit and the Mount Jordan Pit. The Hansen-Lehi Pit is on the 

east side of I-15 and the Mount Jordan Pit is on the west side of I-15. Aggregate material is 

mined from open pits and processed in aggregate processing equipment. The processed 

aggregate is then sent off site or used to produce concrete or hot mix asphalt. The equipment 

at the Point of the Mountain Facility consists of crushers, screens, conveyors, other aggregate 

processing equipment, hot mix asphalt equipment (dryers, baghouses, heaters, storage bins, 

etc), concrete batch plant equipment (mixers, baghouses, storage silos, boilers, etc.), and 

various diesel generators. 

Current Permits: 

DAQE-AN0105650018-09 dated November 30, 2009 (Hansen-Lehi) 

DAQE-AN0127760005-09 dated April 2, 2009 (Mount Jordan) 

SIP:

The Geneva Rock Products Point of the Mountain Facility was listed in 2.2.P in the 1994 SIP 

and in Section IX, Part H (e) in the 2005 SIP. These sections have been included in this 

document. 

5.b.i - 49
Existing Actual Emissions (from 2008 inventory) for the Hansen-Lehi Pit

82.81 26.02 14.13 102.11 18.61 58.25 0 0 0 0

Emissions Information / Discussion 

The emission information above is from the 2008 inventory. The facility went through a permit modification in 2009, which increased 

potential emissions; however, production at the facility was high in 2008 and has since decreased, which would result in a lower 

actual emission rate. In evaluating emission rates for the SIP, the total emissions from the facility were kept at the 2008 levels, but 

the percentage of what emissions were coming from what source were adjusted to reflect the current permit numbers. From the 

2008 inventory, 54.4% of the NOx emissions, 8.7% of the SO2 emissions, and 37.6% of the VOC emissions are tailpipe emissions 

from mobile equipment (loaders, dozers, etc.). Production limits, which are contained in the 2005 SIP, keep emissions below Title V 

thresholds. 

5.b.i - 50
PM2.5 RACT Options 

Fugitive Dust Sources (Storage Piles, Haul Roads, Exposed Areas, etc.) 

Control Options: 

Depending on the source, controls for PM2.5 emissions from fugitive dust sources could include 

the following: 

Enclosures, 

Conveyors, 

Wind Breaks, 

Chemical Suppressants, 

Water Application, 

Vegetation, 

Paving, 

Best Management Practices, 

Technical Feasibility: 

The controls listed above are all technically feasible in most situations. In active mining areas, 

the terrain is consistently changing, so the only potential options would be water application and 

best management practices. Water application may also be infeasible if the terrain prevents 

water trucks or water cannons from reaching the mining area. Chemical suppressants may also 

be technically infeasible where the chemicals could come into contact with the product and 

negatively impact the quality of the product. 

Economic Feasibility: 

The PM2.5 fraction of fugitive dust emissions is small (10% - 40% of PM10); therefore, most 

control options are considered expensive when compared to the amount of PM2.5 that is 

controlled from fugitive dust sources. 

The least expensive option for storage piles and exposed areas was chemical suppressants 

(MgCl). Chemical suppressants would cost over $24,000 per ton of PM2.5 removed from 

storage piles. This did not include the additional water that would needed to supplement the 

chemical suppressants. For haul roads, the amount of emissions is proportional to the amount 

of product produced. Paving costs are around $4,600 per ton of PM2.5 removed for haul roads 

that have 8,000,000 tons of product transported on them. All haul roads that have this amount 

of material transported on them are already paved at the Point of the Mountain Facility. Water 

application is already used on all unpaved haul roads, so no additional reductions would result 

from further evaluation of controls on haul roads. 

Implementation Schedule: 

The RACT analysis determined that no additional controls for fugitive dust sources than what is 

already being conducted at the Point of the Mountain Facility would be required. To obtain 

reductions from other fugitive dust sources, the DAQ has proposed changes to R307-309. 

5.b.i - 51
Aggregate Processing Equipment (Crushers, Screens, Conveyors, etc.) and 

Concrete Batch Plants 

Control Options: 

Controls for PM2.5 emissions from aggregate processing equipment include the following: 

Water Application, 

Enclosures, 

Add-on Control Device: 

 Baghouse, 

 Electro Static Precipitator 

 Wet Scrubber 

 Cyclone 

Technical Feasibility: 

The controls listed above are all technically feasible in most situations. Water cannot be used in 

concrete batch plants because the material must remain dry until mixing. In the mixing process 

a specified amount of water is added, and too much water will affect product quality. 

Economic Feasibility: 

Water application has been determined to be economically feasible for aggregate processing 

equipment. The additional enclosures and add-on control devices for aggregate processing 

equipment was determined to be economically infeasible. Since water cannot be used to 

control emissions from concrete batch plants, baghouse and fabric filter controls are 

economically feasible. Emission rates from this equipment vary depending on the amount of 

material being processed. The current NSPS Subpart OOO has opacity limits for new 

equipment as follows: Crushers – 12%, Screens – 7%, Conveyors – 7%, and Baghouses/Fabric 

Filters – 7%. Equipment and cost modifications to the existing equipment would be minimal for 

a source to meet these standards. 

 

Approximate Cost: 

For aggregate processing equipment, water application was determined to be around $650 per 

ton of PM2.5 removed. The existing concrete batch plant at the Point of the Mountain Facility 

already has baghouse and fabric filter controls; therefore, a cost estimate was not obtained from 

this source. 

Implementation Schedule: 

Most sources are already meeting the proposed limits above. Any modifications to existing 

equipment can be made before the June 2013. To obtain reductions from aggregate processing 

equipment and concrete batch plants throughout the PM2.5 nonattainment area, the DAQ has 

proposed R307-312 to control emissions from the aggregate processing industry. All aggregate 

processing operations, including Geneva Rock Products - Point of the Mountain Facility, will be 

required to comply with R307-312 to reduce emissions. 

5.b.i - 52
Hot Mix Asphalt Plants 

Control Options: 

Controls for PM2.5 emissions from hot mix asphalt plants include the following: 

Add-on Control Device: 

 Baghouse, 

 Electro Static Precipitator 

 Wet Scrubber 

 Cyclone 

Technical Feasibility: 

The controls listed above are all technically feasible to control filterable PM2.5 emissions. No 

controls were identified that would control condensable PM2.5 emissions from hot mix asphalt 

plants. 

Economic Feasibility: 

All controls listed above are economically feasible to control filterable PM2.5 emissions. The 

option with the highest control efficiency is the baghouse. Since 1995, filterable PM10 emission 

rates from hot mix asphalt plants have been at or lower than 0.024 grains per dry standard cubic 

foot of air (gr/dscf). If a source can meet the PM10 limit, the source can meet the same limit for 

PM2.5. A more stringent limit was not used because exact PM2.5 emission rates were not 

available. A few condensable PM emission rates were available, but values varied between 5% 

and 85% of the total PM values. Due to the inconsistent condensable emission rates and the 

lack of potential controls for condensable emissions, a limit was not included for condensable 

emissions. 

 

Approximate Cost: 

All facilities constructed after 1995 would be required to meet the 0.024 gr/dscf limit; therefore, 

there would be no cost to these facilities. Sources would be required to retrofit their plants older 

than 1995 to come into compliance with the limit. 

Implementation Schedule: 

Most sources are already meeting the proposed limits above. In the current PM10 

nonattainment areas, sources are required to conduct a stack test of permit limits every three 

years; therefore, compliance must be demonstrated within three years of issuance of the SIP. 

To obtain reductions from hot mix asphalt plants throughout the PM2.5 nonattainment area, the 

DAQ has proposed R307-312 to control emissions from the aggregate industry. All hot mix 

asphalt plants, including Geneva Rock Products - Point of the Mountain Facility, will be required 

to comply with R307-312 to reduce emissions by December 14, 2015. 

5.b.i - 53
Stationary Diesel-Fired Engines 

Control Options: 

Controls for PM2.5 emissions from stationary diesel-fired engines include the following: 

Diesel Particulate Filters (DPF) 

Engine Design: 

 Tier I 

 Tier II 

 Tier III 

 Tier IVi 

Technical Feasibility: 

DPF may be used to meet the emission standards listed under the engine design, so this 

specific technology was not evaluated. Each tier has separate requirements for different sized 

engines. 

Economic Feasibility: 

Engines that provide primary power to aggregate processing operations are usually greater than 

900 hp. Smaller engines usually operate periodically and do not generate enough emissions to 

be economically feasible to be retrofitted with controls. Costs were evaluated for engines 

greater than 900 hp, but the Geneva Rock Products - Point of the Mountain Facility does not 

have any stationary diesel-fired engines rated 900 hp or greater. Therefore, no further analysis 

was conducted for diesel-fired engines. 

5.b.i - 54
NOx & SO2 RACT Options 

Hot Mix Asphalt Plants 

Control Options: 

Controls for NOx and SO2 emissions from hot mix asphalt plants include the following: 

Low-NOx Burners, 

SCR, 

NSCR, 

SO2 Scrubber, 

Low Sulfur Fuels, 

Other Fuels Include: 

 Waste Oil 

 Fuel Oil/Heating Oil 

 Natural Gas/Propane 

Technical Feasibility: 

All the controls listed above are all technically feasible; however, SCR, NSCR, and SO2 

Scrubbers have not been used to control emissions from hot mix asphalt plants in Utah. Most 

facilities are equipped with Low-NOx burners, so further reductions cannot be obtained. The 

add-on controls listed above were not evaluated further. 

Economic Feasibility: 

Hot mix asphalt plants are able to utilize a variety of fuels. The fuel that generates the lowest 

emissions is natural gas or propane. The fuel that generates the highest emissions is 

waste/used oil. Natural gas produces approximately half of the NOx emissions that waste oil 

produces; however, the combustion of waste oil has beneficial uses in that the waste oil is not 

disposed of as a hazardous waste. The cost of the fuel used has a great effect on the final cost 

of the product. As of August 2012, natural gas was the cheapest fuel available for hot mix 

asphalt plants; however, if natural gas prices increase or if waste oil prices decrease, it may not 

be economically feasible to use natural gas. During the winter inversion season (November 1st

to March 1st), production of hot mix asphalt is significantly reduced. To allow sources the 

flexibility to utilize different fuels as necessary during the inversion season, sources will be 

required to reduce hot mix asphalt production by half when utilizing a fuel other than natural 

gas. The resulting NOx and SO2 reductions will then be reflected in the SIP model. 

Approximate Cost: 

Fuel prices vary over time. As of August 2012, there would be no cost to sources. If natural 

gas prices increase or if waste oil prices decrease, the source would be required to produce 

less product; however, since this would only apply during the inversion season, production 

would already be reduced, so it is expected that there would be minimal cost to sources. 

Implementation Schedule: 

To obtain reductions from hot mix asphalt plants throughout the PM2.5 nonattainment area, the 

DAQ has proposed R307-312 to control emissions from the aggregate industry. All hot mix 

asphalt plants, including Geneva Rock Products - Point of the Mountain Facility, will be required 

to comply with R307-312 to reduce emissions. 

5.b.i - 55
Results of Analysis 

The following was determined to represent RACT for the Geneva Rock Products - Point of the 

Mountain Facility: 

Fugitive Dust Sources – Control Strategies Listed in R307-309

All Crushers – 12% Opacity 

All Screens – 7% Opacity

All Conveyors – 7% Opacity

All Concrete Batch Plants – 7% Opacity 

All Hot Mix Asphalt Plants – 0.024 gr/dscf 

All Hot Mix Asphalt Plants – 50% production when not using natural gas during 

November 1st to March 1st

Compliance Demonstration Methodology: 

All fugitive dust sources will be required to comply with R307-309 within 30 days of the effective 

date of the rule. All hot mix asphalt plants will be required to comply with the 0.024 gr/dscf limit 

by December 14th 2015. All remaining sources will be required to comply with R307-312 by 

June 7th 2013.

DATE: November 26, 2012 

SUBJECT: FINAL ADOPTION: R307-312. Aggregate Processing Operations for PM2.5 

Nonattainment Areas. 

_______________________________________________________________________________ 

Rule R307-312, Aggregate Processing Operations for PM2.5 Nonattainment Areas, was proposed as part of 

the PM2.5 State Implementation Plan (SIP) with a public comment period from October 1, 2012, to 

November 1, 2012. Public hearings were held on October 15, 16, and 17. The Board specifically 

requested comments on the exclusion of condensable PM2.5 emissions from the hot mix asphalt PM2.5 limit 

and the appropriateness of excluding temporary hot mix asphalt plants from the requirements of R307-312. 

No comments were received regarding these requests. Written comments were received from six 

submitters and EPA. Each comment received was considered. We are recommending changes to the 

proposed rule as a result of some of these comments. The written comments received, along with our 

responses, are identified below. 

Industry Comments 

Richard Thorn with the Associated General Contractors, Larry Jardine with LeGrand Johnson Construction 

Company, John Burggraf with Lakeview Rock Products, Paul Glauser with Oldcastle Inc., and Patrick 

Clark with Staker Parson Companies submitted written comments. The comments are summarized below 

with DAQ’s response. A copy of each written comment is attached to this memo. 

1) Applicability Comments: 

Comments were received regarding the applicability of R307-312 to the entire county instead of just 

the areas of nonattainment. The commenters felt that R307-312 should only apply to the 

nonattainment areas. 

5.b.i - 57
DAQ-102-12

Page 2 

DAQ Response – R307-312 was proposed to apply to sources located in the entire counties of Box 

Elder, Cache, Davis, Salt Lake, Tooele, Utah, or Weber Counties. DAQ agrees with commenters that 

this rule should only apply to sources in PM2.5 nonattainment or maintenance areas. The language in 

R307-312 was changed to the following: “PM2.5 nonattainment and maintenance area as defined in 40 

CFR 81.345 (July 1, 2011) and geographically described as all regions of Salt Lake and Davis 

counties; all portions of the Cache Valley; all regions in Weber and Utah counties west of the Wasatch 

mountain range; in Box Elder County, from the Wasatch mountain range west to the Promontory 

mountain range and south of Portage; and in Tooele County, from the northernmost part of the Oquirrh 

mountain range to the northern most part of the Stansbury mountain range and north of Route 199.” 

2) Opacity Method Comments: 

Comments were received about the method to determine compliance with the opacity limits in R307-

312. The opacity limits in R307-312 are the same as the opacity limits in 40 CFR 60 Subpart OOO. 

The method specified in Subpart OOO is 30 minutes (five 6-minute averages). Commenters felt it was 

unreasonable to not specify this method in R307-312. Paul Glauser with Oldcastle Inc. and Patrick 

Clark with Staker Parson Companies suggested adding the following language: “During air quality 

inspections, State Inspectors would perform a six minute Method 9 observation. If the initial six 

minute average is below the opacity limit, the observation would be deemed complete. If the initial six 

minute average indicated conditions exceeding the limit, a full 30 minute reading would be required to 

determine noncompliance.” 

DAQ Response – The 30 minutes (five 6-minute averages) was left out of R307-312-4 due to the 

additional time and resources that DAQ would have to spend during compliance inspections. Due to 

the commenters making suggestions, the language for the 30 minutes (five 6-minute averages) was 

added to the rule with the following sentence: “The duration of Method 9 may be reduced to 6 minutes 

(one six-minute average) if the first six-minute average is below the limit specified in Table 1.” This 

will keep DAQ resources spent during inspections manageable, while allowing the averaging time to 

remain the same as the averaging time in 40 CFR 60 Subpart OOO. 

Public Comments 

Joro Walker with Western Resource Advocates submitted written comments. The comments are 

summarized below with DAQ’s response. 

1) Reasonable Available Control Technology (RACT) for Fugitive Dust Sources: 

Without basis in the record, the RACT for Geneva Rock Products states that "most control options are 

considered expensive when compared to the amount of PM2.5 that is controlled from fugitive dust 

sources." Reliance on the proposed changes to R307-309 to establish RACT for fugitive dust is 

unavailing as our previous comments on that rule indicate. 

DAQ Response – Details of the RACT analysis including cost of additional controls are listed in the 

technical support document (TSD) for R307-312. The TSD indicates that additional controls than what 

are already being implemented at the Geneva Rock Products: Point of the Mountain Facility would 

cost over $100,000 per ton of PM2.5 removed. In accordance with DAQ practices and previous 

evaluations, this value was determined to be too expensive to be economically feasible for the source 

to implement. R307-309 addresses reasonable controls for fugitive dust. Comments on R307-309 

were addressed during the rulemaking process for R307-309. 

5.b.i - 58
DAQ-102-12

Page 3 

2) RACT for Hot Mix Asphalt Plants: 

The RACT for Hot Mix Asphalt Plants does not adequately address PM2.5 emissions and without 

adequate basis in the record, relies on an emission limit that is almost 20 years old. 

DAQ Response – Stack testing for PM2.5 has not been conducted in Utah for hot mix asphalt plants. 

Test methodology for condensable PM2.5 is relatively new, and accurate information, including 

emission factors, is limited. The value selected as RACT is more stringent than federal New Source 

Performance Standards (NSPS) and is based on DAQ longstanding practice. This value is reasonable 

until more data can be gathered. Once additional data is gathered, a new limit could be proposed if 

determined necessary. 

EPA Comments 

EPA submitted written comments. The comments are summarized below with DAQ’s response. 

1) RACT: 

Lack of RACT analysis for the source category; e.g., no information on range of control technologies 

considered, control efficiencies, or other state rules evaluated. 

DAQ Response – A RACT analysis was conducted for the aggregate processing equipment (crushers, 

screens, & conveyors), concrete batch plants, and hot mix asphalt plants. A spreadsheet in the TSD 

included control options for each source. Each control option was given a control efficiency or 

emission rate. Technically infeasible options were determined and were not evaluated further. An 

evaluation of environmental, energy, and economic impacts was conducted for the remaining control 

options. Limits were obtained from this evaluation and are included in R307-312. Other State of Utah 

rules were not included in the TSD, because no other Utah rules address these issues. Rules in other 

states were not evaluated because Utah specific sources were involved with the creation of this rule. 

Federal rule NSPS 40 CFR 60 Subpart OOO was evaluated with this rule. 

2) Monitoring, Recordkeeping, Reporting, Testing (MRRT): 

There are no MRRT requirements in the draft rule. 

DAQ Response – There are MRRT requirements in the draft rule. R307-312-6(2) and (3) require 

sources to test PM2.5 from the hot mix asphalt plants and report the test results to the Director. A 

sentence was added to R307-312-5(2)(a) to require sources to keep records of production and fuel use 

to determine compliance with R307-312-5(2). The opacity limits in R307-312 do not have MRRT 

requirements. DAQ has a compliance monitoring strategy that is submitted to EPA annually for 

review, and these sources are included in the list of sources identified in that strategy. 

3) Definitions: 

R307-312 only has seven definitions while the South Coast Air Quality Management District 

(SCAQMD) has 54 definitions. The term “aggregate processing” is not defined in the rule. 

Compliance could be hampered by lack of definition in the rule. Consideration should be given to 

defining more terms like the SCAQMD rule. 

DAQ Response – R307-312-3 and R307-101-2 contain definitions related to R307-312. Other words 

not defined in these rules are common words defined in a standard dictionary. The term “aggregate” is 

5.b.i - 59
DAQ-102-12

Page 4 

only listed in the title and purpose of the rule. Any limits of the rule refer to “nonmetallic mineral” as 

defined in R307-312. The word aggregate has several definitions; therefore, to avoid any confusion on 

which definition this rule refers, “aggregate” will be added to the definitions section of R307-312. 

4) PM10 SIP Conflict: 

Parts of R307-312 may conflict with the Utah PM10 SIP for Geneva Rock Products: Hansen Pit and 

Mount Jordan Pit. The PM10 SIP for this source has limits on crushers of 10% opacity, on screens of 

10% opacity, on conveyor transfer points of 10% opacity, on conveyor drop points of 15% opacity. 

DAQ Response – R307-312 was written to encompass all aggregate processing plants in the PM2.5

nonattainment area; therefore, these sources were evaluated in addition to Geneva Rock Products. 

R307-312 has more stringent requirement for screens and conveyor transfer points than the PM10 SIP 

for Geneva Rock Products. The PM10 SIP for Geneva Rock Products has more stringent requirement 

for crushers than R307-312. R307-312 does not contain requirements for conveyor drop points. 

Geneva Rock Products will be required to comply with the most stringent limit, whether the limit is 

contained in R307-312, the PM10 SIP, 40 CFR 60 Subpart OOO, or other rule. 

5) Work Practice Standards: 

The draft rule does not provide any work practice standards for achieving the specified visible 

emission limits. The SCAQMD rule specifies the use of dust suppressants or other dust control 

methods to meet the visible emission standards, but does not specify work practice standards. A 

separate SCAQMD rule provides detailed work practice standards that apply to aggregate-related 

plants and cement manufacturing facilities. 

DAQ Response – Work practice standards were not included in R307-312 for several reasons. First, 

work practices for fugitive dust are mentioned in R307-309. Second, we did not want to specify the 

control a source would have to use in case a better alternative was discovered later. The DAQ requires 

compliance with the limit, not how the source decides to comply with the limit. Third, R307-309-6 

requires sources to submit a fugitive dust control plan. The fugitive dust control plan allows the source 

to specify which controls will be used to meet the limits in the rules. 

6) Alternative Controls: 

Alternate controls were not provided in the draft rule. The SCAQMD rule requires baghouses (fabric 

filters) for crushing and screening equipment, and allows for the use of dust suppressions or other dust 

control methods to meet visible emission standards as an alternative. 

DAQ Response – R307-312 does not require specific controls that a source must use. Specific controls 

were not required in case other technology was developed that was more efficient. Specific controls, 

including baghouses, were evaluated during the RACT analysis. Baghouses and other controls were 

eliminated due to economic impacts to the sources. In the RACT analysis, baghouse control was 

estimated to cost over $33,000 per ton of PM2.5 removed. Water application was estimated to cost only 

$651 per ton of PM2.5 removed. Baghouse control is only estimated to increase control efficiency by 

3%. This high additional cost for the small additional reduction is unreasonable for sources; therefore, 

baghouse control is not required in R307-312. 

5.b.i - 60
DAQ-102-12

Page 5 

7) Control Efficiency (CE): 

CE was not identified in the draft rule. 

DAQ Response – CE was not listed in R307-312; however, CE was supplied in the TSD for several 

control options. The emission rate for crushers, screens, and conveyors cannot be measured prior to 

control; therefore, the PM2.5 emission rate after control is what is limited in the rule. 

8) Rule Effectiveness (RE): 

RE of 80% is not supported. 

DAQ Response – EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 

2: Non-Point Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of 

Ozone and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, 

EPA 12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is 

newly regulating an area, there is no enforcement history to reference, therefore, DAQ applied the 

former EPA default RE of 80% that has been used in former SIP’s. 

Staff Recommendation: Staff recommends the Board adopt R307-312 as amended.

The technical specifications for this portion of the rule has not been amended and 

consistent with the EPA approved rule (2/14/2006, 71 FR 7679). 

According to EPA comments of July 2, 2012, enforcement records show there are only 

six tank sources located within Salt Lake, Utah, Weber, Summit and Box Elder counties. 

DAQ has reviewed the 186 compliance advisories for the years 2009-2012 and could 

only find one violation in 2009 in Salt Lake County for improper tank cover 

management. Given the small number of sources and one violation, we conclude there 

is a high compliance rate which would be higher than the 80% that was applied in the 

SIP.

SUBJECT: FINAL ADOPTION: R307-335. Degreasing and Solvent Cleaning Operations. 

______________________________________________________________________________________ 

On July 11, 2012, the Board proposed for public comment amendments to R307-335, Degreasing and 

Solvent Cleaning Operations. The proposed rule would expand the current rule to the PM2.5 nonattainment 

areas and add a new section for industrial solvent cleaning performed outside of degreasing tanks. 

The public comment period was held from August 1 to August 31, 2012. DAQ received many comments 

from the aerospace industry and from one industry that treats miscellaneous metals parts. A hearing was 

held on August 15, 2012. Attendees were solely from the aerospace industry. 

Summary of Public Comments: 

The aerospace industry opposed the rule because the proposed industrial solvent cleaning requirements 

could not be implemented for that industry. Staff reviewed their concerns and concurred with their 

comments. Staff resolved this issue by inserting a new exemption in the rule for the aerospace industry and 

by developing a separate rule for the aerospace industry based on an EPA model rule. 

A commenter also pointed out that the Resource Conservation and Recovery Act (RCRA) requirements 

already address waste solvent disposal and recycling. Staff concurs and has deleted that section from the 

proposed rule. 

Additional modifications were made based on public comment: 

1. The applicability was changed from county-wide to the area defined as the nonattainment area. 

2. New exemptions were added under the industrial solvent cleaning section for areas already 

regulated under separate rules. 

5.b.i - 67
DAQ-082-12 

Page 2 

3. The implementation schedule was adjusted to assure that sources regulated under the existing rule 

will continue to be regulated while sources in the rest of the nonattainment area will be required to 

comply with the rule by September 1, 2013. 

EPA Comments: 

The following is a summary of the substantive comments EPA submitted: 

1. The rule should include recordkeeping. 

 Response: Agreed. A new recordkeeping section has been added. 

2. The rule should require at least 85% control efficiency for add-on controls. 

 Response: All required control measures in the rule already provide at least 85% efficiency by virtue 

of the type of control. Carbon absorption technology efficiency degrades as activated carbon sites 

become saturated therefore, we are adding text to require continuous efficiency at 85% or greater. 

3. Increase carbon efficiency requirement above 85% if further reductions are necessary to meet 

attainment. 

 Response: Carbon absorption efficiency increases with molecular weight above 50 and is most 

efficient for high molecular weight solvents like carbon tetrachloride, which was commonly used when 

this rule was originally enacted. The RCRA waste management regulations, along with HAP air 

quality rules lead to the migration to less toxic substitutes with a lower affinity for carbon absorption. 

Current solvent use does not lend itself to reasonable higher efficiency controls; therefore, we cannot 

arbitrarily require a higher efficiency than 85%. 

Staff Recommendation: Staff recommends the Board adopt the amendments to R307-335.

RACT Analysis Summary 

EPA issued the Control Techniques Guidelines for Miscellaneous Industrial Adhesives 

(CTG), EPA-453/R-08-005, September 2008. CTGs issued for VOCs are presumptive 

RACT. EPA developed its recommended approaches in the CTG based on the analysis 

of existing state and local emission reduction approaches as follows. 

In 1998, the California Air Resources Board issued a guidance document for the 

industry that was based on eight existing California air pollution control district rules. 

The Board determined that their guidance was RACT. In 2007, the Ozone Transport 

Commission (OTC) issued a model rule for adhesives and sealants that was based on 

the 1998 RACT determination. The model rule achieves VOC reductions through two 

basic components: sale and manufacture restrictions that limit VOC content of specified 

adhesives, sealants and primers sold and use restrictions that apply to 

5.b.i - 74
commercial/industrial applications. Area source VOC reduction occurs by reducing the 

availability of higher VOC content adhesives and sealants within the nonattainment 

areas.

DATE: January 14, 2013 

SUBJECT: PROPOSE FOR PUBLIC COMMENT: R307-342. Adhesives and Sealants.

______________________________________________________________________________________ 

The purpose of this rule is to limit emissions of volatile organic compounds (VOCs) from adhesives, 

sealants and primers that apply primarily to commercial and industrial applications. R307-342 applies to 

any person who manufactures, sells, supplies, or applies any adhesive, sealant, adhesive primer, or sealant 

primer in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, or Weber counties on or after September 1, 

2014. R307-342 is being proposed as part of the PM2.5 State Implementation Plan (SIP). 

According to the Department of Workforce Services, two product manufactures in Utah may be subject to 

this rule: 

Quality Emulsions, LLC Lehi 5-9 employees No Permit 

TCR Composites, Inc. Ogden 50-99 employees Permitted for 6.6 tpy VOC 

Advance notice of prospective rulemaking was sent to these facilities. The Utah Manufacturers 

Association also received advanced rulemaking notice (see attached). 

These products are predominately manufactured outside of Utah by firms such as 3M; therefore, staff has 

collaborated with the American Coatings Association, Inc. (ACA), a trade association that represents the 

coating industry. The ACA supports this rulemaking because it is consistent with the national regulatory 

structure. ACA requested that the rule include sufficient time for manufactures and suppliers to sell their 

existing inventory. 

Advance notifications to major manufacturers outside the state will be made through the ACA.

Reasonable Available Control Technology (RACT) Analysis 

EPA issued the Control Techniques Guidelines (CTG) for Miscellaneous Industrial Adhesives, EPA453/R-08-005, September 2008. CTGs issued for VOCs are presumptive RACT. EPA developed its 

recommended approaches in the CTG based on the analysis of existing state and local emission reduction 

approaches as follows. 

In 1998, the California Air Resources Board issued a guidance document for the industry that was based on 

eight existing California air pollution control district rules. The Board determined that their guidance was 

RACT. In 2007, the Ozone Transport Commission (OTC) issued a model rule for adhesives and sealants 

that was based on the 1998 RACT determination. The model rule achieves VOC reductions through two 

basic components: sale and manufacture restrictions that limit VOC content of specified adhesives, 

sealants, and primers sold and use restrictions that apply to commercial/industrial applications. Area 

source VOC reduction occurs by reducing the availability of higher VOC content adhesives and sealants 

within the nonattainment areas.

We are recommending the OTC model approach in order to obtain maximum VOC reduction because the 

OTC is more stringent. 

Area Source Estimated VOC Reductions 

Emission reductions are calculated as follows: 

 Emission Reduction = [control efficiency (CE) x rule effectiveness (RE)] x rule penetration (RP) 

CE is a term that defines the expected emission reduction by implementing a rule. The CTG estimates a 

CE of 64% (CTG page 21) which is too low for the proposed rule because the proposed rule includes VOC 

limits on cleaning materials that are not included in the CTG. 

The EPA database AirControlNET provides a CE of 73% (page III-1293) for the 1996 version of the South 

Coast Air Quality Management District (SCAQMD) Rule 1168. The 1996 version required an 80% VOC 

emission control which is lower than the 85% in this rule; therefore, this CE is also understated. 

A reasonable CE would be to apply the SCAQMD 73% plus 2% for the more stringent proposed rule for a 

CE of 75%. 

RE is a term that describes a method to account for the reality that not all facilities covered by a rule are in 

compliance with the rule 100% of the time. In this case, national manufacturing companies will be 

responsible for providing product to Utah in compliance with the coating limits thereby simplifying 

5.b.i - 77
DAQ-004-13 

Page 3 

compliance. We normally apply an RE of 80% for new rulemaking; however, because this rule is based on 

national product development and delivery, an RE of 100% is applied (AirControlNET page III-1293 – RE 

of 100%). 

RP is an estimate of the percentage of emissions emitted by facilities covered by a regulation. Because this 

rule is based on national product development and delivery, an RP of 100% is applied (AirControlNET 

page III-1293 – RP of 100%). 

Final Emission Reduction = 75% CE or 565 ton reduction. 

Cost Estimation 

AirControlNET states that the 1996 version of the SCAQMD Rule 1168 

cost $2,202/ton VOC removed in 1990 dollars or $5,730 in 2011 

(Williamson, 2012, using economic cost method). As with the CE, this 

may be understated because of the higher VOC removal rate required in 

this rule. We intend to request cost information during the public 

comment. 

Staff Recommendation: Staff recommends the Board propose for public comment R307-342, Adhesives 

and Sealants, with a specific request for cost data.

An analysis of compliance records from 2009-2012 showed that there was no violation 

for this rule indicating an RE greater than 90% however, DAQ applied an RE of 80% as 

a conservative measure because the amended rule includes more stringent limits. 

RACT Analysis Summary 

The RACT analysis was based on the EPA Control of Volatile Organic Compound

Emissions from Wood Furniture Manufacturing Operations (CTG), EPA 453/R-96-007, 

April 1996. The CTG provides a model rule. This guidance document provides a 

presumptive RACT. 

EPA stated in their comments that the proposed rule, while meeting the CTG model, is 

outdated and that DAQ should consider reducing the applicability and coating limits. We 

recognize that the CTG is dated, which is why we originally proposed to reduce the 

5.b.i - 89
applicability from 25 tpy to 5 tpy. Upon re-evaluation of this rule and in comparison to 

other coating rules, we are now proposing to further reduce the applicability to 2.7 tpy, 

consistent with other coating rules. Lacking more current EPA guidance on coating 

limits for this industry, we believe that phasing in limits at half the current limits is a 

reasonable means to gain further VOC reductions.

DATE: November 27, 2012 

SUBJECT: PROPOSE FOR PUBLIC COMMENT: Change in Proposed Rule. R307-343. Emissions 

Standards for Wood Furniture Manufacturing Operations. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from wood furniture 

manufacturing. 

The rule reduces VOCs by requiring owners and operators of wood furniture manufacturing operations to 

use coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technology 

Guideline (CTG), Control of Volatile Organic Compound Emissions from Wood Furniture Manufacturing 

Operations, EPA 453/R-96-007, April 1996. The CTG provides a model rule. This guidance document 

provides a presumptive RACT. 

On September 5, 2012, the Board proposed for public comment R307-350. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the sole commenter. 

EPA stated in their comments that the proposed rule, while meeting the CTG model, is outdated and that 

DAQ should consider reducing the applicability and coating limits. We recognize that the CTG is dated, 

which is why we originally proposed to reduce the applicability from 25 tons per year (tpy) to 5 tpy. Upon 

re-evaluation of this rule and in comparison to other coating rules, we are now proposing to further reduce 

the applicability to 2.7 tpy, consistent with other coating rules. Lacking more current EPA guidance on 

coating limits for this industry, we believe that phasing in limits at half the current limits is a reasonable 

5.b.i - 91
DAQ-113-12 

Page 2 

means to gain further VOC reductions. Therefore, we are proposing to release for public comment the 

amended rule. We are also asking the industry to provide their costs to implement the rule. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. The rule applicability is lower than the CTG recommendation but not as low as other states. 

Response: We recognize that the CTG is dated and that the applicability should be lower than the CTG 

recommended 25 tpy. We are proposing to lower the applicability to 2.7 tpy, consistent with most of 

our other coating rules. 

3. The coating limits are consistent with the CTG, but other states have lower limits. There is also a 

labeling error on Table 1. 

Response: DAQ has re-evaluated the coating limits. We recognize that the limits are dated and have 

proposed a phase-in of lower limits. 

The labeling error in Table 1 is noted. 

4. Training and other work practices recommended in the CTG are not included. 

Response: This CTG is dated. Newer coating CTGs for other industries do not require the same work 

practices. We have modified this rule to be consistent with other coating rules. 

5. There are no VOC limits on cleaning solvents. 

Response: Agreed. The rule has been amended to include a VOC content limit on cleaning solvents. 

6. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

Monitoring, testing and reporting protocols are more suited within the site permit to fashion the 

requirements to site specificity. 

7. The rule lacks restrictions and labeling requirements for sales of coatings and solvents. 

Response: Manufacturers are not constrained in manufacturing coatings and solvents with higher 

limits. This is not a statewide rule. Manufacturers produce a wide variety of products and those 

facilities who cannot substitute with a product having a lower VOC content will have to use add-on 

controls. After all, the intent of offering an add-on control option is to permit use of material having a 

higher VOC content. The structure of this rule is the same as the current R307-340, Nonattainment 

and Maintenance Areas: Surface Coating, which has been approved by EPA in a prior state 

implementation plan. Our experience with the coating/chemical manufactures’ labeling indicates that 

major manufacturers already provide information on total VOC and exempt VOC content on their 

labels and data sheets so that they can distribute their products nationwide. 

5.b.i - 92
DAQ-113-12 

Page 3 

8. Cost control documentation is not verifiable. 

Response: The cost for extending the current coating limits was taken from the South Coast Air 

Quality Management District (SCAQMD) rule in 1996, $1,414 = $2,260/ton VOC removal in 2011 

dollars. 

9. Control efficiency (CE) documentation is lacking. 

Response: The control efficiency was derived from the CTG by dividing the expected reduction from 

the baseline emissions. However, a calculation error was made, and EPA is correct that the CE should 

be 47%. We will make the appropriate changes. 

10. The rule effectiveness (RE) of 80% is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

While enforcement data for counties where this rule currently applies indicates that we could apply the 

guidance Range 1, where we would normally apply 90%, the rule applicability has been reduced 

significantly, such that we feel 80% is more appropriate. 

Staff Recommendation: Staff recommends the Board propose for public comment R307-343 as amended.

16 "Affected source" means a wood furniture manufacturing source 

17 that meets the criteria in R307-343-2. 

18 "As applied" means the volatile organic compound and solids 

19 content of the finishing material that is actually used for coating 

20 the substrate. It includes the contribution of materials used for 

21 in-house dilution of the finishing material. 

22 [ "Capture device" means a hood, enclosed room, floor sweep, or 

23 other means of collecting solvent emissions or other pollutants into 

24 a duct so that the pollutant can be directed to a pollution control 

25 device such as an incinerator or carbon adsorber. 

26 "Certified product data sheet (CPDS)" means documentation 

27 furnished by a coating supplier or an outside laboratory that provides 

28 the volatile organic compound content by percent weight, the solids 

29 content by percent weight, and the density of a finishing material, 

30 strippable booth coating, or solvent, measured using EPA Method 24 

31 or an equivalent method, or formulation data if the coating meets the 

32 criteria specified in R307-343-7(1).] 

33 "Coating" means a protective, decorative, or functional material 

34 applied in a thin layer to a surface. Such materials may include paints,

38 booth coating that meets the emission limits specified in 

39 R307-343-4(1). 

40 [ "Control device" means any equipment that reduces the quantity 

41 of a pollutant that is emitted to the air. The device may destroy 

42 or secure the pollutant for subsequent recovery. Control devices 

43 include, but are not limited to, incinerators, carbon adsorbers, and 

44 condensers. 

45 "Control device efficiency" means the ratio of the pollution 

46 released by a control device and the pollution introduced to the control 

47 device, expressed as a fraction.] 

48 "Control system" means the combination of capture and control 

49 devices used to reduce emissions to the atmosphere. 

50 "Conventional Air Spray" means a spray coating method in which 

51 the coating is atomized by mixing it with compressed air at an air 

52 pressure greater than ten pounds per square inch (gauge) at the point 

5.b.i - 94
R307-343 November 27, 2012 Page 2 of 6 

1 of atomization. Airless, air assisted airless spray technologies, 

2 and electrostatic spray technology are not considered conventional

9 in an oven, or cured by radiation. 

10 [ "Normally closed container" means a container that is closed 

11 unless an operator is actively engaged in activities such as emptying 

12 or filling the container.] 

13 "Sealer" means a finishing material used to seal the pores of 

14 a wood substrate before additional coats of finishing material are 

15 applied. A washcoat used to optimize aesthetics is not a sealer. 

16 "Solids" means the part of the coating that remains after the 

17 coating is dried or cured; solids content is determined using data 

18 from EPA Method 24. 

19 "Stain" means any color coat having a solids content by weight 

20 of no more than 8.0% that is applied in single or multiple coats directly 

21 to the substrate, including nongrain raising stains, equalizer stains, 

22 sap stains, body stains, no-wipe stains, penetrating stains, and 

23 toners. 

24 [ "Strippable booth coating" means a coating that: 

25 (1) Is applied to a booth wall to provide a protective film to 

26 receive overspray during finishing operations; 

27 (2) Is subsequently peeled off and disposed; and 

28 (3) By achieving (1) and (2), reduces or eliminates the need 

29 to use organic solvents to clean booth walls.] 

30 "Topcoat" means the last film-building finishing material applied 

31 in a finishing system. Non-permanent final finishes are not topcoats. 

32 "Touch-up and Repair" means the application of finishing 

33 materials to cover minor finishing imperfections. 

34 "Washcoat" means a transparent special purpose coating having 

35 a solids content by weight of 12.0% or less that is applied over initial 

36 stains to protect and control color and to stiffen the wood fibers 

37 in order to aid sanding. 

38 "Washoff operations" means those operations in which organic 

39 solvent is used to remove coating from a substrate. 

40 "Wood furniture" means any product made of wood, a wood product 

41 such as rattan or wicker, or an engineered wood product such as 

42 particleboard that is manufactured under any of the following standard 

43 industrial classification codes: 2434, 2511, 2512, 2517, 2519, 2521, 

44 2531, 2541, 2599, or 5712.

R307-343 November 27, 2012 Page 4 of 6 

1 (3) Conventional air spray methods may be used under the 

2 following circumstances: 

3 (a) To apply finishing materials that have no greater than 1.0 

4 pound of VOC per pound of solids, as applied; 

5 (b) For touch-up and repair under the following circumstances: 

6 (i) The touchup and repair occurs after completion of the 

7 finishing operation; or 

8 (ii) The touchup and repair occurs after the application of stain 

9 and before the application of any other type of finishing material, 

10 and the materials used for touchup and repair are applied from a 

11 container that has a volume of no more than 2.0 gallons; 

12 (c) When the spray gun is aimed and triggered automatically, 

13 not manually; 

14 (d) When the emissions from the finishing application station 

15 are directed to a control device; 

16 (e) When the conventional air gun is used to apply finishing 

17 materials and the cumulative total usage of that finishing material 

18 is no more than 10% of the total gallons of finishing material 

19 used during the calendar year; or 

20 (f) When the conventional air gun is used to apply stain on a 

21 part for which it is technically or economically infeasible to use 

22 any other spray application technology. The following criteria shall 

23 be used, either independently or in combination, to support the 

24 affected source's claim of technical or economic infeasibility: 

25 (i) The production speed is too high or the part shape is too 

26 complex for one operator to coat the part and the application station 

27 is not large enough to accommodate an additional operator; or 

28 (ii) The excessively large vertical spray area of the part makes 

29 it difficult to avoid sagging or runs in the stain.

R307-344 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was no violation for this rule indicating an RE greater than 90% 

however, DAQ applied an RE of 80% as a conservative measure because the rule 

includes more stringent limits than the original R307-340. 

RACT Analysis Summary 

The RACT analysis was based on the EPA Control Technologies Guidelines for Paper, 

Film, and Foil Coatings (CTG), EPA 453/R-07-003, September 2007. This guidance 

document provides a presumptive RACT. In May 1977, EPA issued a CTG for surface 

coating on paper that was used in rulemaking for R307-340-5 and promulgated the new 

source performance standards (NSPS) in 1983 for coatings of pressure sensitive tape 

and labels, a subset of paper, film and foil. EPA promulgated the NESHAP in 2002 for 

5.b.i - 100
paper and other web coating. EPA developed the recommendations in the 2007 CTG 

after reviewing the earlier CTG, the NSPS and NESHAP. The VOC RACT limits were 

taken from the CTG, Table 1, page 18.

DATE: November 26, 2012 

SUBJECT: FINAL ADOPTION: R307-344. Paper, Film, and Foil Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from roll, knife, and 

rotogravure coaters and drying ovens of paper, film, and foil coating operations. This rule replaces R307-

340-5. 

The rule reduces VOCs by requiring owners and operators of paper, film, and foil coatings operations to 

use coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines for Paper, Film, and Foil Coatings (CTG), EPA 453/R-07-003, September 2007. This guidance 

document provides a presumptive RACT. In May 1977, EPA issued a CTG for surface coating on paper 

that was used in rulemaking for R307-340-5. EPA promulgated the new source performance standards 

(NSPS). In 1983 for coatings of pressure sensitive tape and labels, a subset of paper, film and foil. EPA 

promulgated the NESHAP in 2002 for paper and other web coating. EPA developed the recommendations 

in the 2007 CTG after reviewing the earlier CTG, the NSPS, and national emission standards for hazardous 

air pollutants (NESHAP). 

On September 5, 2012, the Board proposed for public comment R307-344. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the only commenter.

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records.

The applicability for this rule is as low as 2.7 tons per year. Requiring monitoring, testing and 

reporting protocol for all area sources does not meet the economic reasonableness test. Any facility 

that is sufficiently large to have add-on controls would require a permit, where these items would be 

addressed on a site specific basis. 

3. Clarify that the 90% efficiency applies to the control device or the control system. Overall control not 

specified.

Response: The 90% efficiency applies to the control device. DAQ believes that defining generic 

capture efficiency requirements in rules is counterproductive. Facility-specific requirements are more 

appropriately addressed in a permit. The CTG supports this premise stating that it is unreasonable or 

feasible to retrofit all facilities to attain a very high overall capture like 95% because it would require 

100% capture (CTG, pages 17-18). 

4. The rule does not include application and transfer efficiency requirements. 

Response: While the CTG does not provide recommendations, we agree it should be added. 

5. There are no VOC limits on cleaning solvents. 

Response: While the CTG specifically stated that EPA was not providing a recommendation for VOC 

content for cleaning materials, we believe it should be included. The rule has been amended to include 

a cleaning limit.

6. Cost control of $1,440/ton is not verifiable. EPA’s CoST Model lists $1,200-1,500/ton. 

Response: The technical support document (TSD) will be revised as follows: $1,200/ton (CTG EPA 

453/R-07-003, page 21) in 2002 dollars = $1,440/ton in 2011VOC removal. 

7. The rule effectiveness (RE) of 80% is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference. In this case, the proposed rule includes 

limits for surface coating that are not currently regulated; therefore, we applied the former EPA default 

RE of 80% that has been used in prior state implementation plans (SIPs). 

Staff Recommendation: Staff recommends the Board adopt R307-344 as amended.

RACT Analysis Summary 

1. The RACT analysis was based on the EPA Control Technologies Guidelines, 

Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles and Light-Duty 

Trucks, EPA 450/2-77-008. This guidance document provides a presumptive 

RACT. However, the CTG is aged therefore, UDAQ consider other state rules as 

part of the RACT analysis.

2. The South Coast Air Quality Management District rule 1128 and the San Joaquin 

Valley Air Pollution Control District rule 4607 were evaluated. Both rules include 

a VOC content limit of 2.2 lb/gal for these materials. UDAQ chose to adopt this 

stringent limit.

SUBJECT: FINAL ADOPTION: R307-345. Fabric and Vinyl Coatings. 

_____________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from fabric and vinyl 

coating operations, which use roll, knife, or rotogravure coaters and drying ovens. This rule replaces R307-

340-6. 

The rule reduces VOCs by requiring owners and operators of fabric and vinyl coatings operations to use 

coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines (CTGs), Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles, and Light-Duty Trucks, 

EPA 450/2-77-008. This guidance document provides a presumptive RACT. 

Initial inventory analysis conducted as part of the state implementation plan (SIP) process indicated that we 

had limited emissions from this sector, so we did not pursue further RACT analysis. Late into the SIP 

process, we discovered that there is a growing market for car wraps and emissions from this industry would 

apply to this rule. This later development has led us to re-evaluate the coating limits. EPA commented 

that the South Coast Air Quality Management District (SCAQMD) Rule 1128 and the San Joaquin Valley 

Air Pollution Control District (SJVAPCD) Rule 4607 limits are more stringent. DAQ has determined that 

coating limit reductions should be phased-in to permit industry sufficient time to adjust their business 

model, especially given this later notice.

On September 5, 2012, the Board proposed for public comment R307-348. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the only commenter. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. Other states have more stringent coating limits. 

Response: Please see above RACT summary. 

3. Clarify that the 90% efficiency applies to the control device or the control system. 

Response: The 90% efficiency applies to the control device. 

4. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year (tpy). Requiring monitoring, testing and 

reporting protocol for all area sources does not meet the economic reasonableness test. Any facility 

that is sufficiently large to have add-on controls would require a permit, in which these items will be 

addressed on a site-specific basis. 

5. The rule does not include application and transfer efficiency requirements. 

Response: Agreed. The rule has been amended to include those from the SCAQMD. 

6. There are no VOC limits on cleaning solvents. 

Response: A VOC limit on cleaning solvents has been added. 

7. The EPA CoST model cost and control effectiveness are very different than what DAQ cited. 

Response: DAQ derived its values from the CTG. Cost was adjusted to present value. EPA did not 

explain the reference used in CoST to estimate a variability of over $2,000/ton between EPA and DAQ 

values, nor did it state whether that is in 2011 dollars. EPA states that the control efficiency in their 

model is 97% but did not explain whether that is for the CTG VOC control limits or for the lower 

limits found in the California rules. Phasing in lower VOC control limits will increase cost and result 

in control efficiency increase. We will apply the 60% control efficiency in our modeling until the 

phase-in of the tighter limits in 2015. At that point, we will use 97% control efficiency. 

8. The rule effectiveness (RE) of 80% is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

5.b.i - 110
DAQ-112-12 

Page 3 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

Staff Recommendation: Staff recommends the Board approve for final adoption R307-345 as amended.

R307-346 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was no violation for this rule indicating an RE greater than 90% 

however, DAQ applied an RE of 80% in the newly regulated counties as a conservative 

measure. 

RACT Analysis Summary 

The RACT analysis was based on the EPA Control Technologies Guidelines for Metal 

Furniture Coatings (CTG), EPA 453/R-07-005, September 2007. This guidance 

document provides a presumptive RACT. This CTG supersedes the original CTG 

published in 1977. EPA published the new source performance standards (NSPS) in 

1982 and the NESHAP in 2003. The 2007 CTG incorporated recommendation from the 

5.b.i - 115
first CTG, the NSPS and the NESHAP. UDAQ chose to apply the limits directly from 

the CTG listed on page 23.

SUBJECT: FINAL ADOPTION: R307-346. Metal Furniture Surface Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from metal furniture 

surface coating operations. This rule replaces R307-340-7. 

The rule reduces VOCs by requiring owners and operators of metal furniture surface coatings operations to 

use coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines for Metal Furniture Coatings (CTG), EPA 453/R-07-005, September 2007. This guidance 

document provides a presumptive RACT. This CTG supersedes the original CTG published in 1977. EPA 

published the new source performance standards (NSPS) in 1982 and the national emission standards for 

hazardous air pollutants (NESHAP) in 2003. The 2007 CTG incorporated recommendation from the first 

CTG, the NSPS, and the NESHAP. 

On September 5, 2012, the Board proposed for public comment R307-348. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the only commenter. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

5.b.i - 117
DAQ-106-12 

Page 2 

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year. Requiring testing protocol for all area 

sources does not meet the economic reasonableness test. Any facility that is sufficiently large to have 

add-on controls would require a permit, in which monitoring, testing and reporting would be addressed 

on a site-specific basis. 

3. Clarify that the 90% efficiency applies to the control device or the control system. Overall control not 

specified. 

Response: The 90% efficiency applies to the control device. We believe that defining generic capture 

efficiency requirements in rules is counterproductive. Facility-specific requirements are more 

appropriately addressed in a permit. 

4. The rule does not include application and transfer efficiency requirements. 

Response: Agreed. The rule has been amended to include those similar to San Joaquin Valley Unified 

Air Pollution Control District (SJVUAPCD) Rule 4603. 

5. There are no VOC limits on cleaning solvents. 

Response: Agreed. The rule has been amended to include a limit consistent with those in SJVAPCD 

Rule 4603 and South Coast Air Quality Management District (SCAQMD) Rule 1107. 

6. The rule lacks restrictions related to sales or labeling requirements. 

Response: Manufacturers are not constrained in manufacturing coatings with higher limits. This is not 

a statewide rule. Manufacturers produce a wide variety of products and those facilities that cannot 

substitute for a product with a lower VOC content will have to use add-on controls. After all, the 

intent of offering an add-on control option is to permit use of materials with a higher VOC content. 

The structure of this rule is the same as the current R307-340, Nonattainment and Maintenance Areas: 

Surface Coating, which has been approved by EPA in a prior state implementation plan (SIP). Our 

experience with the automotive coating manufactures’ labeling indicates to us that major 

manufacturers already provide information on total VOC and exempt VOC content on their labels and 

data sheets so that they can distribute their products nationwide. 

7. Cost control documentation is lacking. 

Response: The cost information was taken from AirControlNet, page III-1362 because we question 

how the recommended limits in the CTG can result in a cost savings (as stated in the CTG). We 

believe that the AirControlNet value of $1,000/ton in 1990 dollars = $2,020/ton in 2011 VOC removal 

is more realistic. 

8. The rule effectiveness (RE) of 90% in Davis and Salt Lake counties and 80% in the remaining counties 

is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

5.b.i - 118
DAQ-106-12 

Page 3 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

The use of 90% was based on compliance data for Davis and Salt Lake counties for the existing rule. 

That data shows that Range 1 of the guidance could be applied. We chose the lower value of 90% 

within Range 1 because we are tightening the control limits per the CTG, which will require timely 

response by sources within these counties. 

Staff Recommendation: Staff recommends the Board approve for final adoption R307-346 as amended.

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year. Requiring monitoring, testing and reporting 

protocol for all area sources does not meet the economic reasonableness test. Any facility that is 

sufficiently large to have add-on controls would require a permit, where these items would be 

addressed on a site-specific basis. 

3. Clarify that the 90% efficiency applies to the control device or the control system. Overall control not 

specified. 

Response: The 90% efficiency applies to the control device. We believe that defining generic capture 

efficiency requirements in rules as counterproductive. Facility-specific requirements are more 

appropriately addressed in a permit. 

4. The rule does not include application and transfer efficiency requirements. 

Response: Agreed. These have been added. 

5. The rule lacks restrictions related to sales or labeling requirements. 

Response: Manufacturers are not constrained in manufacturing coatings with higher limits. This is not 

a statewide rule. Manufacturers produce a wide variety of products and those facilities who cannot 

substitute a product with a lower VOC content will have to use add-on controls. After all, the intent of 

offering an add-on control option is to permit use materials having a higher VOC content. The 

structure of this rule is the same as the current R307-340, Nonattainment and Maintenance Areas: 

Surface Coating, which has been approved by EPA in a prior SIP. Our experience with the automotive 

coating manufactures’ labeling indicates to us that major manufacturers already provide information on 

total VOC and exempt VOC content on their labels and data sheets so that they can distribute their 

products nationwide. 

6. There are no VOC limits on cleaning solvents. 

Response: While the CTG specifically addresses this issue, stating that EPA is not recommending use 

of VOC content limits for cleaning materials, we believe it should be included. The rule has been 

amended to include a cleaning limit. 

7. Cost control and control efficiency documentation is not verifiable. 

Response: We have re-evaluated the cost and control efficiency. We believe that the cost would be 

more in line with $2,027/ton, especially with the addition of VOC content limits for cleaning materials. 

Likewise we believe that EPA is correct with a control efficiency=55%. DAQ will make those 

changes. 

8. The rule effectiveness (RE) of 90% in Davis and Salt Lake counties and 80% in the remaining counties 

is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

5.b.i - 126
DAQ-105-12 

Page 3 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

The use of 90% was based on compliance data for Davis and Salt Lake counties for the existing rule. 

That data shows that Range 1 of the guidance could be applied. We chose the lower value of 90% 

within Range 1 because we are tightening the control limits per the CTG, which will require timely 

response by sources within these counties. 

Staff Recommendation: Staff recommends the Board approve for final adoption R307-347 as amended.

R307-348 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was no violation for this rule indicating an RE greater than 90% 

however, DAQ applied an RE of 80% in the newly regulated counties as a conservative 

measure. 

RACT Analysis Summary 

1. There are no EPA guidance documents (ACT or CTGs) that directly apply to this 

industry. 

2. The NESHAP - Surface Coating of Miscellaneous Metal Parts and Products, FR Vol. 

69, No. 1, January 2, 2004, applies to facilities with 10 tpy or more of any one HAP or 

25 tpy or more of any combination of HAPs. This NESHAP is not directly applicable, 

5.b.i - 131
but some components are sufficiently similar, permitting us to reference the control 

efficiency and cost information. 

3. The South Coast Air Quality Management District (SCAQMD) rule 1126 - coating 

limits and the 90% incineration efficiency requirement of the proposed R307-348 are the 

same as the SCAQMD rule 1126. 

UDAQ concluded from the RACT analysis that the emission limit is sufficiently stringent 

and that minor rule amendments were necessary to address EPA comments.

DATE: November 20, 2012

SUBJECT: FINAL ADOPTION: R307-348. Magnet Wire Coatings. 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from ovens of magnet wire 

coating operations. 

On September 5, 2012, the Board proposed for public comment R307-348, which replaces the magnet wire 

coating section of R307-340. 

The rule reduces VOCs by requiring owners and operators of coating ovens to use coatings with a VOC 

content established in the rule, to use add-on controls to achieve a 90% VOC reduction, or to use a 

combination of applying coatings with the required VOC content and add-on controls. 

The reasonable available control technology (RACT) analysis process was based on the following: 

1. There are no EPA guidance documents (Alternative Control Techniques or Control Technology 

Guidelines) that directly apply to this industry. 

2. The National Emission Standards for Hazardous Air Pollutants (NESHAP) - Surface Coating of 

Miscellaneous Metal Parts and Products, FR Vol. 69, No. 1, January 2, 2004, applies to facilities 

with 10 tons per year (tpy) more of any one hazardous air pollutant (HAP) or 25 tpy or more of any 

combination of HAPs. This NESHAP is not directly applicable, but some components are 

sufficiently similar, permitting us to reference the control efficiency and cost information. 

3. The South Coast Air Quality Management District (SCAQMD) rule 1126, approved by EPA. The 

coating limits and the 90% incineration efficiency requirement of the proposed R307-348 are the 

same in the SCAQMD rule 1126. 

5.b.i - 133
DAQ-096-12 

Page 2 

We concluded that the current rule meets RACT objectives. 

The public comment period was held from October 1 to November 1, 2012. Public hearings were held on 

October 15, 16, and 17. Hill Air Force Base and EPA provided comments. 

Hill Air Force Base Comments 

1. Exempt solvents should not be included in the VOC coating content. 

Response: Agreed. The rule has been amended accordingly. 

2. Section R307-348-4(2) (b) should be revised to read “The use of an add-on control device on magnet 

wire coating ovens....” 

Response: Agreed. The rule has been amended accordingly. 

3. The applicability should be limited to the PM10 and PM2.5 nonattainment/maintenance areas. 

Response: We believe that it is more practical to implement industrial rules on a county level; 

however, a structured implementation schedule has been added for Box Elder and Tooele counties. 

4. The compliance schedule should be extended for three years to accommodate those that may be newly 

regulated and have to add engineering controls. 

Response: Sources in Davis and Salt Lake counties are subject to this rule as of the effective date 

because the rule is the same as the requirements presently in R307-340-9. In other words, there is no 

change for those sources. A three year implementation schedule for the other counties would be 

beyond the mandatory compliance date of 2014. Those counties have until January 1, 2014, 

approximately one year. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: As explained in item 4 above, this is an established requirement presently in R307-340-9. 

The RACT analysis summary is provided above. 

2. The monitoring, recordkeeping, reporting, and testing requirements are insufficient. 

Response: The recordkeeping and reporting information in R307-348 is the same as that in SCAQMD 

rule 1126, requiring inventory and data sheet documentation as approved by EPA. Remaining 

compliance is based on documentation that add-on controls meet requirements in R307-348-6. The 

applicability for this rule is as low as 2.7 tpy. Requiring testing protocol for all area sources does not 

meet the economic reasonableness test. Any facility that is sufficiently large to have add-on controls 

would require a permit, in which testing and reporting are addressed. 

4. No VOC limits on cleaning solvents are included. 

Response: We disagree. DAQ is proposing an industrial cleaning rule (R307-335-7) that applies to all 

industries that is the same as the EPA reference to SCAQMD. 

5. The rule does not include a capture efficiency requirement for add-on controls. 

Response: Capture efficiency is addressed in the permitting process to accommodate facility and 

technological variability. The EPA-approved SCAQMD automotive refinishing rule includes this 

same provision because EPA recognizes that capture efficiency cannot always be standardized. 

5.b.i - 134
DAQ-096-12 

Page 3 

6. The rule cost and control effectiveness referenced in the technical support document (TSD) cannot be 

verified. 

Response: DAQ cited the EPA database AirControlNet, page III-1332, electrical coating. The control 

efficiency and cost in the EPA database are for the maximum achievable control technology (MACT) 

standard. This was the closest reference staff was able to find that could be used. The database cited 

1990 cost which was adjusted to current value, as explained in the TSD. 

7. The rule effectiveness (RE) of 80% for Box Elder, Cache, Tooele, Utah, and Weber counties are not 

supported and lack documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating in an area, there is no enforcement history to reference, therefore, DAQ applied the former 

EPA default RE of 80% that has been used in former SIP’s. 

Staff Recommendation: Staff recommends the Board approve for final adoption R307-348 as amended.

R307-349 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was no violation for this rule indicating an RE greater than 90% 

however, DAQ applied an RE of 80% as a conservative measure because the rule 

includes more stringent limits than the original R307-340. 

RACT Analysis Summary 

1. The RACT analysis was based on the EPA Control Technologies Guidelines for 

Flat Wood Paneling Coatings (CTG), EPA 453/R-06-004, September 2006. This 

guidance document provides a presumptive RACT. This CTG supersedes the 

original CTG published in 1978. The CTG did include consideration of the 

5.b.i - 140
NESHAP issued in 2003. For all flat wood operations, the CTG recommends the 

use of a new limit of 2.1 lb VOC/gallon or an add-on control with 90% efficiency. 

2. We also evaluated air quality rules in California. 

UDAQ concluded that the emission standard is sufficiently stringent but that the rule 

was lacking requirements for coating transfer efficiency that was added to the rule.

SUBJECT: FINAL ADOPTION: R307-349. Flat Wood Panel Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from flat wood paneling 

coating sources. This rule replaces R307-340-10. 

The rule reduces VOCs by requiring owners and operators of flat wood panel coatings operations to use 

coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines for Flat Wood Paneling Coatings (CTG), EPA 453/R-06-004, September 2006. This guidance 

document provides a presumptive RACT. This CTG supersedes the original CTG published in 1978. The 

CTG did include consideration of the national emission standards for hazardous air pollutants (NESHAP) 

issued in 2003. For all flat wood operations, the CTG recommends the use of a new limit of 2.1 lb 

VOC/gallon or an add-on control with 90% efficiency. 

We also evaluated air quality rules in California. For example, the San Joaquin Valley Unified Air 

Pollution Control District (SJVUAPCD) Rule 4606 permits higher coating limits for a variety of 

categories. We chose to amend the rule per the CTG using one coating limit across all categories. 

The estimated cost in the CTG is $2,600/ton VOC removal in 2005 dollars, assuming facilities would 

switch to stains with lower VOC content. 

 

On September 5, 2012, the Board proposed for public comment R307-349. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the only commenter.

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. Clarify that the 90% efficiency applies to the control device or the control system. 

Response: The 90% efficiency applies to the control device. 

3. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year. Requiring monitoring and testing protocol 

for all area sources does not meet the economic reasonableness test. Any facility that is sufficiently 

large to have add-on controls would require a permit, in which monitoring, testing and reporting would 

be addressed on a site specific basis. 

4. The rule does not include application and transfer efficiency requirements. 

Response: Agreed. The rule has been amended to include those similar to SJVUAPCD Rule 4606. 

5. The rule lacks restrictions related to sales or labeling requirements. 

Response: Manufacturers are not constrained in manufacturing coatings with higher VOC content. 

This is not a statewide rule. Manufacturers produce a wide variety of products and those facilities who 

cannot substitute for a lower VOC product will have to use add-on controls. After all, the intent of 

offering an add-on control option is to permit use of higher VOC limits. The structure of this rule is 

the same as the current R307-340, Nonattainment and Maintenance Areas: Surface Coating, which has 

been approved by EPA in a prior state implementation plan(SIP). Our experience with the automotive 

coating manufactures’ labeling indicates to us that major manufacturers already provide information on 

total VOC and exempt VOC content on their labels and data sheets so that they can distribute their 

products nationwide. 

6. There are no VOC limits on cleaning solvents. 

Response: Agreed. The rule has been amended to include limits consistent with those in SJVUAPCD 

Rule 4606. 

7. The 34% control efficiency (CE) is not sufficiently documented. 

Response: Agreed. In fact, it appears that we made an error in our calculations. The actual CE should 

be 60% (interior paneling) as per the CTG Appendix C, page 19. This will be corrected. 

5.b.i - 143
DAQ-109-12 

Page 3 

8. The rule effectiveness of 90% in Davis and Salt Lake counties and 80% in the remaining counties is 

not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

The use of 90% was based on compliance data for Davis and Salt Lake counties for the existing rule. 

However, we have lowered that to 80% because the emission limits have been extensively reduced in 

keeping with our other rule REs where we have made major rule revisions. 

Staff Recommendation: Staff recommends the Board adopt R307-349 as amended.

23

24 R307-349-3. Definitions.

25 The following additional definitions apply to R307-349: 

26 "Coating" means a protective, decorative, or functional material 

27 applied in a thin layer to a surface. Such materials may include 

28 paints, topcoats, varnishes, sealers, stains, washcoats, basecoats, 

29 inks, and temporary protective coatings.

30 "Finishing material" means a coating used in the flat wood panel 

31 industry, including basecoats, stains, washcoats, sealers, and 

32 topcoats.

34 decorative interior, exterior or tileboard (class I hardboard) panel 

35 to which a protective, decorative, or functional material or layer 

36 has been applied.

37 "Sealer" means a finishing material used to seal the pores of 

38 a wood substrate before additional coats of finishing material are 

39 applied. A washcoat used to optimize aesthetics is not a sealer.

40 “Strippable booth coating” means a coating that is applied to 

41 a booth wall to provide a protective film to receive overspray during 

42 finishing and that is subsequently peeled and disposed. Strippable 

43 booth coatings are intended to reduce or eliminate the need to use 

44 organic solvents to clean booth walls.

SUBJECT: FINAL ADOPTION: R307-350. Miscellaneous Metal Parts and Products Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from miscellaneous metal 

parts and products coating operations. This rule replaces R307-340-11. 

The rule reduces VOCs by requiring owners and operators of miscellaneous metal parts and products 

coatings operations to use coatings with a VOC content established in the rule or to use add-on controls to 

achieve a 90% VOC reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines for Miscellaneous Metal and Plastic Parts Coatings (CTG), EPA 453/R-08-003, September 

2008. This guidance document provides a presumptive RACT. This CTG supersedes the original CTG

On September 5, 2012, the Board proposed for public comment R307-350. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

Public comments were received from EPA, Nucor, American Coatings Association, Boeing, Hill Air Force

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

 

Response: Please see above RACT summary. 

2. The monitoring, recordkeeping, reporting, and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year. Requiring monitoring, testing, and 

reporting protocol for all area sources does not meet the economic reasonableness test. Any facility 

that is sufficiently large to have add-on controls would require a permit, where these items would be 

addressed on a site specific basis. 

3. Clarify that the 90% efficiency applies to the control device or the control system. Overall control not 

specified. 

Response: The 90% efficiency applies to the control device. DAQ believes that defining generic 

capture efficiency requirements in rules is counterproductive. Facility-specific requirements are more 

appropriately addressed in a permit. 

4. There are no VOC limits on cleaning solvents. 

Response: Agreed. The rule has been amended to include a cleaning limit. 

5. Section R307-350-6(8) allows for director’s discretion. 

Response: That section has been reworded to exclude the director’s discretion, but retains the transfer 

efficiency requirement. 

6. Cost control documentation is lacking and the 35% control efficiency (CE) from an EPA database is 

not verifiable. The 2008 CTG cites a 35% CE. 

Response: The TSD for this rule cites CE- EPA-453/R-08-003 as the source of the 35%, as EPA has 

confirmed. However, the CTG CE did not include reductions for VOC limits for cleaning solvents and 

we are adopting strict VOC limits for cleaning solvents. Essentially, our CE value is understated. 

The cost information was taken from the CTG, page 40, $1,758/ton in 2004 dollars = $2,020 in 2011. 

This value is also understated at this point when considering the cost of reducing VOC from cleaning 

solvents. This cost should also apply to special maintenance, which will be corrected in the TSD. 

7. The rule effectiveness (RE) of 90% in Davis and Salt Lake counties and 80% in the remaining counties 

is not supported and lacks documentation. 

Response: EPA directed us to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

5.b.i - 151
DAQ-103-12 

Page 3 

regulating in an area, there is no enforcement history to reference; therefore, we applied the former 

EPA default RE of 80% that has been used in former SIPs. 

The use of 90% was based on compliance data for Davis and Salt Lake counties for the existing rule. 

That data shows that Range 1 of the guidance could be applied. We chose the lower value of 90% 

within Range 1 because we are tightening the control limits per the CTG, which will require timely 

response by sources within these counties. 

Hill Air Force Base Comments 

1. R307-350 only exempts exteriors of aircraft while the aerospace rule R307-355 applies to interior and 

exterior. This overlap in rules can be resolved by revising the exemption in R307-350-3 to aerospace 

vehicles and components. This comment was also submitted by Boeing and ATK. 

Response: Agreed. The change has been made in R307-350. 

2. Include the definition of “aerospace vehicles and components.” 

Response: Agreed. A definition has been added. 

3. Include electrodeposition as an approved application method. 

Response: Agreed. It has been added to R307-350-6. 

4. Remove solvent washing in R307-350-5(2) because it is addressed in R307-350-7. 

Response: Agreed. The washing requirement should be removed from R307-350-5(2) because a VOC 

reduction limit for solvent washing has been inserted based on EPA comment. 

5. The application methods listed in R307-350-3(2) should be exempt from the entire rule. 

Response: The CTG states, “we are recommending that only the recommended work practices, but not 

the recommended VOC limits and application methods, apply to the following types of coatings.” The 

rule is consistent with guidance. No change is warranted. 

6. The implementation schedule should be delayed for three years to permit HAFB to begin the process of 

switching to low-VOC alternatives. This process will require a Department of Defense Technical 

Order change. 

Response: The compliance schedule for Davis County is September 1, 2013. Further discussion with 

base personnel indicates that this date may be sufficient. 

7. Change the applicability to those areas defined as nonattainment and maintenance areas only. 

Response: Practical implementations of certain types of rules are more effective on a county basis. 

This rule fits that criterion. No change is warranted. 

8. HAFB identified potential definition errors. 

Response: The proposed errors were reviewed and those that were, in fact, in error were corrected.

American Coatings Association (ACA) Comments 

The ACA provided suggested language for the work practice and recordkeeping section which was revised 

per EPA comments on that subject. 

ATK Comments 

1. ATK requested an exemption for surface coating of munitions consistent with the exemption provided 

by EPA under the NESHAP (EPA-453/R-03-008, August 2003, page 25). 

Response: DAQ reviewed the rational EPA provided in the NESHAP for this exemption and concurs. 

The exemption has been added. 

2. The rule should also exempt coatings that occur at research or laboratory facilities, janitorial, building 

and facility maintenance operations. 

Response: The CTG only excluded coatings from research and laboratory operations at paint research 

and manufacturing. The CTG does not address janitorial coatings and we are not sure what would 

generate sufficient VOCs to become applicable. The CTG does address building coatings, stating that 

those are architectural coatings that are not covered under miscellaneous metals. Our review indicates 

that exemptions in R307-350 should not be altered based on this comment. 

Nucor Comments 

1. Nucor is challenging the definition of baked coating. 

Response: The definition was taken directly from the CTG. 

2. Nucor is challenging the limit for “VOC less water.” 

Response: The coating limit, less water and exempt solvents, comes directly from the CTG and is the 

norm for all coating limits in all industries. 

3. Nucor is challenging the variability in the limits between air dried and baked. 

Response: The coating limits were taken directly from the CTG. 

4. The exemption for touch up and repair coatings from spray cans should be expanded to exempt these 

devices from all sections of the rule. 

Response: The exemption, as written, is derived directly from the recommendation within the CTG. 

Staff Recommendation: Staff recommends the Board adopt R307-350 as amended.

R307-351 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was one violation for excess temperature setting on a catalyst 

at a printing facility. Even with this one occurrence, an RE greater than 90% is valid 

however, DAQ applied an RE of 80% as a conservative measure for newly regulated 

counties and 90% in currently regulated counties because the rule includes more 

stringent limits than the original R307-340.

SUBJECT: FINAL ADOPTION: R307-351. Graphic Arts. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from printing operations. 

This rule replaces R307-340-12. 

The rule reduces VOCs by requiring owners and operators to use coatings with a VOC content established 

in the rule or to use add-on controls to achieve between 80 - 90% VOC reduction, dependent on the type of 

printing operation. 

The reasonable available control technology (RACT) analysis was based on the following: 

1. EPA Control Technologies Guidelines (CTG) for Offset Lithographic printing and Letterpress 

Printing, EPA 453/R-06-002, September 2006. This guidance document provides a presumptive 

RACT. The guidance document is based on findings EPA made in their initial studies dating back 

to 1993. 

2. EPA CTG for Flexible Package Printing, EPA 453/R-06-003, September 2006. This CTG 

incorporates the recommendations made in a CTG published in 1978 for rotogravure printing and 

flexible printing. The 1996 national emission standards for hazardous air pollutants (NESHAP) for 

the printing and publishing industry is also given consideration in this CTG. This CTG is also a 

presumptive RACT. 

3. Technological advancements have changed the face of the industry to the extent that the printing 

industry has modified its business model. The digital age, along with economic recession has 

resulted in negative industry growth. Business analysts have projected negative three percent 

industry growth for the next four years. At the same time, the industry NESHAP has spurred 

5.b.i - 164
DAQ-116-12 

Page 2 

significant coating reformulation nationwide, even though the NESHAP targeted larger facilities. 

Consequently, DAQ worked collaboratively with the national association, the Printing Industries of 

America, to assure that this rule reflects actual current conditions where VOC emission have 

already been reduced and that further rulemaking will not adversely impair viability of the 

industry. 

The Board proposed R307-351 for public comment on September 5, 2012. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

Public comments were received from EPA, Printing Industries of Utah, and a printing operator. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: R307-351-7 requires that records be kept of the monthly use of all materials that may be a 

source of VOC emissions including, but not limited to, inks, coatings, adhesives, fountain solution, 

cleaning materials, and solvents. 

Monitoring, reporting and testing requirements are more appropriately addressed in a facility permit 

where they may be fashioned to fit site specificity. 

3. The applicability section in the rule is less inclusive than South Coast Air Quality Management District 

(SCAQMD) and San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). 

Response: The current rule applicability in R307-340-12 is 100 tons per year (tpy). Emission 

standards in the proposed rule have been reduced to 25 tpy, in keeping with the CTG 

recommendations. The applicability for work practices that include VOC reductions for certain 

solutions and cleaners is at 2.7 tpy for all sources. 

The AirControlNet, page III-1340 states that the “RACT-level controls to small graphic arts sources” 

based on low or no VOC materials would range from $3,500-$4,800/ton in 1993 dollars. We chose to 

use the AirControlNet recommended cost of $4,150/ton, adjusted to $5,890/ton of VOC removed based 

on current value. The upper bound cost for RACT has not yet been defined. We are still conducting 

the RACT analysis for all industries; and once that is completed, we will define an upper cost 

boundary. In the interim, we are recommending that the emission standard for this rule remain at 25 

tpy. In the event that the upper cost boundary reaches above $5,890/ton, we will re-assess the need to 

revise this rule to a lower threshold. 

4. VOC standards under R307-351-4 Standards for Rotogravure, Flexographic and Specialty Printing 

Operations may be outdated. 

Response: We recognize that some aspects of the CTG’s are dated. Please refer to the discussion in 

the RACT summary and cost evaluation in comment #3 for the rational to maintain the limits as 

proposed. 

5.b.i - 165
DAQ-116-12 

Page 3 

5. Minimal number of limits on VOC content of cleaning solvents included. SJVUAPCD and SCAQMD 

specify a maximum that is lower than the 2006 CTG. 

Response: Our industrial solvent cleaning requirements in R307-335-7 offer several options for 

cleaning solvents. One of those options is to use cleaning solutions with vapor pressure less than or 

equal to eight mm Hg at 20° C. The proposed rule includes a VOC composite vapor pressure of less 

than ten mm Hg at 20° C or cleaning materials containing less than 70 weight percent VOC for offset 

lithographic and letterpress printing operations. The requirement in the proposed rule was deemed to 

be a reasonable VOC content. 

6. There are no requirements for sales or labeling of coatings or solvents. 

Response: Manufacturers are not constrained in manufacturing coatings with higher limits. This is not 

a statewide rule. Manufacturers produce a wide variety of products and those facilities who cannot 

substitute for a lower VOC product will have to use add-on controls. After all, the intent of offering an 

add-on control option is to permit use material with a higher VOC content. The structure of this rule is 

the same as the current R307-340, Nonattainment and Maintenance Areas: Surface Coating, which has 

been approved by EPA in a prior state implementation plan (SIP). Our experience with the automotive 

coating manufactures’ labeling indicates to us that major manufacturers already provide information on 

total VOC and exempt VOC content on their labels and data sheets so that they can distribute their 

products nationwide. 

7. Clarify why DAQ has chosen to use 90% control efficiency for dryer emissions for all offset 

lithographic and letterpress printing when the 2006 CTG recommended 95% for units installed after 

2006. 

Response: A 95% device control effectiveness would require 100% capture efficiency, which is not 

practically achievable in this industrial setting. 

8. The cost estimate of $5,890/ton is not verifiable. 

Response: Please refer to comment #3 above. 

9. The rule effectiveness (RE) of 90% in Davis, Salt Lake, and Utah counties and 80% in the remaining 

counties is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

The use of 90% was based on compliance data for Davis, Salt Lake, and Utah counties for the existing 

rule. That data shows that Range 1 of the guidance could be applied. We chose the lower value of 90% 

within Range 1 because the applicability threshold has been substantially lowered.

Printing Industries of Utah Comments 

1. Subsection R301-351-2 (1) states that R307-351-4 applies to specialty printing operations employing 

“solvent containing inks.” There needs to be a definition as to what ink is considered a solvent 

containing ink to differentiate specialty printing operations from flexographic printing operations. 

Response: The phrase “solvent containing ink” has been replaced with the acronym VOC in 

appropriate places within the rule. 

2. Replace the phrase “petroleum ink oils” with VOC. 

Response: Agreed. It has been replaced. 

3. Subsections R301-351-2 (4), (5), and (6) state that the applicability threshold is 2.7 tpy. The CTG 

states it should be 3 tpy. 

Response: The CTG states that the threshold(s) should be 15 lb/day which is approximately equal to 

2.7 tpy. 

4. The definition for “batch” should be added to the rule. 

Response: The word is not used in the rule; therefore, it is not necessary to add it. 

5. The definition for “composite partial vapor pressure” should be added. 

Response: Agreed. It has been added. 

6. The definition for “dampening system” should be added. 

Response: The phrase is not used in the rule; therefore, it is not necessary to add it. 

7. The definition for “sheet-fed” should be added. 

Response: This term is self-evident. It is not necessary to add this to the definitions. 

8. The definition for “blanket” should be revised as recommended. 

Response: Agreed. It has been revised. 

9. The definition for “coating” should be revised to the following: “Coating” means material applied onto 

a substrate. A printing operation which applies coating is not considered a coating operation. 

Response: We disagree with the proposed definition. The definition in the rule was taken from Title 

40 of the Code of Federal Regulations (40 CFR) 63, Subpart KK. The distinction between coating 

operation and printing operation is adequately addressed in the proposed rule in the definition for 

‘printing operation.’ 

5.b.i - 167
DAQ-116-12 

Page 5 

10. The definition for “Flexographic Press” should be removed. It is it confusing and unnecessary as there 

is a definition for “Flexographic printing” which explains the printing process well enough for printing 

operations to determine which control requirements apply to them. 

Response: We disagree. The definition of ‘flexographic press,’ particularly the last sentence in the 

definition, serves as clarification of the units involved, applicability, and originated in 40 CFR 63 

Subpart KK. 

11. The definition for “gravure” should be removed. It is it confusing and unnecessary as there is a 

definition for “Rotogravure printing.” 

Response: Agreed. It has been removed. 

12. The definitions for “roll coating,” “roll printing,” and “rotogravure coating” should be removed, as 

these definitions are not applicable to printing operations and are not necessary for operations to 

determine applicability and control requirements. 

Response: The word “roll” is used in various definitions and its association requires that they all 

remain. 

13. Subsection R307-351-6(2)(a)(i) includes requirements for fountain solution for heatset web offset 

lithographic operations of 1.6% alcohol or less (by weight) in the fountain. This needs to be changed 

to specify the control for the as applied content. The revised subsection would read as follows: (i) 

1.6% alcohol or less by weight on press (as applied) in the fountain solution. 

Response: We have resolved this by removing the phrase “as applied” from subsections 2(a)(ii) and 

2(a)(iii). 

14. Subsection R307-351-6(2)(b)(i) includes requirements for fountain solution for sheetfed offset 

lithographic operations of 5.0% alcohol or less (by weight) in the fountain. This needs to be changed 

to specify the control for the as applied content. The revised subsection would read as follows: (i) 

5.0% alcohol or less by weight on press (as applied) in the fountain solution. 

Response: We have resolved this by removing the phrase “as applied” from subsections R307-351-

6(2)(b)(ii) and (iii). 

15. Subsection R307-351-6(3)(a) includes a an operational limit which allows cleaning materials of less 

than ten mm Hg at 68 degrees Fahrenheit or cleaning materials less than 70 weight percent VOC. 

“Less than” should be changed to “less than or equal to,” per the 2006 CTG. 

Response: The Lithographic CTG does not state “or equal.” It further states that cleaning materials 

are available at “less than” that limit as well. 

16. Remove the requirement to maintain monthly record keeping. 

Response: The recordkeeping requirement has been changed to an annual basis, as per all other 

proposed coating rules. 

5.b.i - 168
DAQ-116-12 

Page 6 

17. Remove the requirement to document device control efficiency in R307-351-8. Replace it with a 

requirement to operate the unit per the manufacturer recommendation. 

Response: Emission control efficiency demonstration is necessary to show compliance. The 

provisions of R307-351-8 have been inserted into each applicable standard subsection. 

18. The implementation schedule requires compliance for sources in Salt Lake and Davis counties upon 

the rule effective date. There is no justification for this requirement. 

Response: These counties are currently regulated under R307-340. Allowing an implementation gap 

would result in “rule backsliding” which is not permissible. 

19. The Association provided additional information on retention factors, capture efficiencies and other 

requirements that they believe should be added to the rule. 

Response: Retention factor addresses the amount of VOC’s that remains on the substrate. We believe 

that this subject is best left to a guidance document, not a rule. The remaining items are most 

appropriately addressed in site permitting. 

Independent Printer Comments 

The commenter stated that he supported nearly all of the provisions of the proposed rule but the monthly 

recordkeeping, which he felt was difficult to accomplish. The monthly recordkeeping has been modified to 

annual recordkeeping. 

Staff Recommendation: Staff recommends the Board approve for final adoption R307-351 as amended.

1 “Offset lithographic printing” means a plane-o-graphic 

2 method in which the image and non-image areas are on the same 

3 plane and the ink is offset from a plate to a rubber blanket, 

4 and then from the blanket to the substrate.

CE- BAAQMD Rule 11, amended June 1999 

R307-352 is a new rule derived from the repealed R307-340 that was in place for over 

20 years. Along with establishing an individual rule for this category, the rule included 

the most current RACT control limits. An analysis of compliance records from 2009-

2012 showed that there was no violation for this rule indicating an RE greater than 90% 

however, DAQ applied an RE of 80% as a conservative measure because the rule is 

newly regulated in most counties and a new requirement was added for metal 

containers. 

RACT Analysis Summary 

The RACT analysis was based on the EPA control technologies guidelines (CTG), 

Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles and Light-Duty Trucks, 

EPA 450/2-77-008. The CTG provided a comparative analysis of existing rules, and 

based on that analysis, we used the Bay Area Air Quality Management District 

Regulation 8, Rule 11 as the primary reference source. The secondary source was 

Rule 1125 from the South Coast Air Quality Management District.

DATE: November 26, 2012 

SUBJECT: FINAL ADOPTION: R307-352. Metal Container, Closure, and Coil Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to reduce volatile organic compound (VOC) emissions from the coating of metal 

coils, cans, pails, and lids. 

The rule reduces VOCs by requiring owners and operators to use coatings with a VOC content established 

in the rule or to use add-on controls to achieve a 90% VOC reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA control technologies 

guidelines (CTGs), Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles and Light-Duty Trucks, 

EPA 450/2-77-008. The CTG provided a comparative analysis of existing rules, and based on that 

analysis, we used the Bay Area Air Quality Management District (BAAQMD) Regulation 8, Rule 11 as the 

primary reference source. The secondary source was Rule 1125 from the South Coast Air Quality 

Management District (SCAQMD). 

On September 5, 2012, the Board proposed for public comment R307-352. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

Comments were received from the American Coatings Association and EPA. 

American Coatings Association Comment 

1. Drums are regulated under this rule and the miscellaneous metals rule. 

Response: Agreed. This oversight has been corrected by removing requirements for drums from this 

rule. 

5.b.i - 180
DAQ-111-12 

Page 2 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: The RACT analysis summary is provided above. 

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. The rule applies to sources emitting down to 2.7 tons per year (tpy), but it is expected that 

facilities engaged in these industrial activities will actually be larger businesses that will require a 

permit. The permit will address monitoring, reporting and testing fashioned to meet facility-specific 

design. 

3. The definition of “coating operation” should be added to the rule. 

Response: The definition of “coil coating” has been modified to define generic coating. 

4. The applicability section does not include coil coating. 

Response: The applicability section has been restructured. Coil coating is identified in the purpose 

statement. 

5. Clarify that the 90% efficiency applies to the control device or the control system. 

Response: The 90% efficiency applies to the control device. 

6. The rule does not include application and transfer efficiency requirements. 

Response: Agreed. The rule has been amended to include those from the SCAQMD. 

7. The applicability cut-off is not clear for coil-coating. 

Response: The applicability threshold has been re-defined. The lowest applicable threshold is 2.7 tpy 

for all coating applications within R307-352. 

8. The rule lacks restrictions related to sales or labeling requirements. 

Response: Manufacturers are not constrained in manufacturing coatings with higher VOC content. 

This is not a statewide rule. Manufacturers produce a wide variety of products and those facilities who 

cannot substitute for a lower VOC product will have to use add-on controls. After all, the intent of 

offering an add-on control option is to permit use of coatings with a higher VOC content. The 

structure of this rule is the same as the current R307-340, Nonattainment and Maintenance Areas: 

Surface Coating, which has been approved by EPA in a prior state implementation plan (SIP). Our 

experience with the automotive coating manufactures’ labeling indicates to us that major 

manufacturers already provide information on to total VOC and exempt VOC content on their labels 

and data sheets. 

9. There are no VOC limits on cleaning solvents. 

Response: A VOC cleaning limit has been added. 

5.b.i - 181
DAQ-111-12 

Page 3 

10. The cost estimate for rule implementation is not verifiable. 

Response: DAQ used the cost from the EPA database AirControlNet, page III-1358 of $2,007 in 1990 

dollars, which is $3,221/ton VOC removal in current value. 

 

11. Rule effectiveness (RE) of 80% for Box Elder, Cache, Tooele, Utah, and Weber counties are not 

supported and lack documentation. 

Response: EPA directed us to use the following EPA guidance in deriving RE, Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

Staff Recommendation: Staff recommends the Board adopt R307-352 as amended.

SUBJECT: PROPOSE FOR PUBLIC COMMENT: Change in Proposed Rule. R307-353. Plastic Part 

Coatings. 

______________________________________________________________________________________ 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from plastic part coating 

lines. The rule reduces VOCs by requiring owners and operators of plastic part coatings operations to use 

coatings with a VOC content established in the rule or to use add-on controls to achieve a 90% VOC 

reduction. 

The reasonable available control technology (RACT) analysis was based on the EPA Control Technologies 

Guidelines for Miscellaneous Metal and Plastic Parts Coatings (CTG), EPA 453/R-08-003, September 

2008. This guidance document provides a presumptive RACT. EPA promulgated a national emission 

standards for hazardous air pollutants (NESHAP) in 2004. EPA developed the recommendations in the 

2008 CTG after reviewing the NESHAP. 

On September 5, 2012, the Board proposed for public comment R307-350. The public comment period 

was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. 

EPA was the sole commenter. 

EPA correctly stated that the CTG contains industrial segments that were not included in the proposed rule. 

DAQ is proposing to amend the rule by adding those industrial sectors and associated coating limits.

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see above RACT summary. 

2. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. 

The applicability for this rule is as low as 2.7 tons per year. Requiring monitoring, testing and 

reporting protocol for all area sources does not meet the economic reasonableness test. Any facility 

that is sufficiently large to have add-on controls would require a permit, where these items would be 

addressed on a site-specific basis. 

3. The rule needs to clarify that the 90% efficiency applies to the control device or the control system. 

The overall control is not specified. 

Response: The 90% efficiency applies to the control device. We believe that defining generic capture 

efficiency requirements in rules as counterproductive. Facility-specific requirements are more 

appropriately addressed in a permit. 

4. The rule lacks transfer efficiency requirements. 

Response: Agreed. The rule has been revised. 

5. The rule applicability section is not as broad as the CTG. 

Response: Agreed. The rule applicability has been revised to include the missing sectors. 

6. There are no VOC limits on cleaning solvents. 

Response: Agreed. The rule has been amended to include a cleaning limit. 

7. Cost control documentation is lacking and the 35% control efficiency (CE) from an EPA database is 

not verifiable. The 2008 CTG cites a 35% CE. 

Response: The technical support document (TSD) for this rule cites CE- EPA-453/R-08-003 as the 

source of the 35%, as EPA has confirmed. However, the CTG CE did not include reductions for VOC 

limits on cleaning solvents and we are adopting strict VOC limits on cleaning solvents. Essentially, 

our CE value is understated. 

The cost information was taken from the CTG, page 40, $1,758/ton in 2004 dollars = $2,020 in 2011. 

This value is also understated at this point when considering the cost of reducing VOC from cleaning 

solvents. 

8. The rule effectiveness (RE) of 80% is not supported and lacks documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

5.b.i - 189
DAQ-107-12 

Page 3 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior state implementation plans (SIPs). 

Staff Recommendation: Staff recommends the Board propose for public comment R307-353 as amended.

SUBJECT: FINAL ADOPTION: R307-354. Automotive Refinishing Coatings. 

______________________________________________________________________________________

The purpose of R307-354 is to limit volatile organic compound (VOC) emissions from automotive 

refinishing sources. R307-354 was proposed as part of the PM2.5 State Implementation Plan (SIP). 

The reasonable available control technology (RACT) analysis process was based on the following: 

1. Two EPA-issued documents—Control Techniques Guideline for Reduction for Volatile 

Organic Compound Emissions from Automobile Refinishing (EPA 450/3-88-009, 1988/10) 

and Alternative Control Techniques Document: Automotive Refinishing (EPA 453/R-94-031, 

1994/04). These documents provide information on the application processes, VOC emissions 

and emission reductions, and costs associated with the use of alternative coating formulations 

and equipment used in automotive refinishing operations. The control techniques guideline 

(CTG) is presumptive RACT. 

2. 40 CFR Part 63, Subpart HHHHHH - National Emission Standards for Hazardous Air 

Pollutants: Paint Stripping and Miscellaneous Surface Coating (6H). This national emission 

standards for hazardous air pollutants (NESHAP) applies to all area sources; therefore, some 

aspects of the NESHAP should be considered in this rulemaking. The NESHAP requires: 

a. All painting, paint preparation, and paint stripping to be done in an enclosed paint booth or 

filtered prep station. This area must have a roof, 3 of the 4 sides enclosed, and have a 

filtered efficiency of at least 98%. 

b. A program to reduce the usage of methylene chloride. This does not apply to R307-354. 

c. Spray guns to be High Volume, Low Pressure (HVLP), or electrostatic, air-assisted airless, 

or airless. Spray gun cleaning must be done in either an enclosed cleaning machine, by 

5.b.i - 198
DAQ-104-12 

Page 2 

hand if spray guns are disassembled, or by flushing the gun with solvent without spraying 

(atomization). Spray gun requirements do apply to R307-354. 

d. All employees conducting activities such as paint stripping and or miscellaneous surface 

coating operations must to be properly trained and retrained. These requirements are 

important but are not replicated in R307-354 because the requirements are already in place 

for all area sources. 

e. Notification of 6H compliance. New facilities must submit their notification of 

compliance (or target date of compliance) no later than 180 days after their initial set-up. 

Existing facilities must have submitted their initial notification of compliance by January 

9, 2010. Full 6H rule compliance was due January 9, 2011. 

f. Recordkeeping requirements – recordkeeping must be maintained for 5 years and must be 

kept on site for at least 2 years: painter training certification with training dates, 

documentation of filter efficiency, documentation from the spray gun manufacturer 

proving the gun is an HVLP or otherwise permitted spray gun, and other requirements 

associated with methylene chloride use. All but the methylene chloride requirements are 

beneficial regarding R307-354. 

3. Other applicable references: South Coast Air Quality Management District (SCAQMD) rule, 

Ozone Transport Commission model rule, and San Joaquin Valley Unified Air Pollution 

Control District (SJVU APCD) rule. 

The proposed rule was released for public comment from October 1 to November 1, 2012. Public hearings 

were held on October 15, 16, and 17. This proposal has elicited significant public interest and missinformation within the industry. Consequently, we provided two evening public education sessions on the 

proposal, which appear to have resolved industry concerns. 

Public and Industry Comments 

1. The insurance industry controls pricing. This rule will increase cost. The cost of equipment will go 

up, citing tens of thousands to hundreds of thousands of dollars. 

Response: Aside from the VOC limits, requirements of 6H are equal to or more stringent than this 

proposal and are already in place. The estimated cost for compliance with this rule is about $2,500/ton 

of VOC removed, which meets the reasonableness test. Cost associated with this rule are 

predominately associated with using lower VOC containing coatings. New equipment would not be 

required under this rule because sources should already be in compliance with 6H. 

 

2. Insufficient study has been conducted to move forward with this rulemaking. Water-borne products 

are inferior and will result in overall higher VOC emissions by having to re-coat. 

Response: Emission reduction studies date back to the 1990s. The industry initially proposed some 

limits to EPA when it discovered that EPA was evaluating the industry. The phase-in of the California 

rules has had a national effect because manufacturers have long ago reformulated to add product lines 

that meet the California standards. Other states already require the limits proposed in this rulemaking. 

3. There are other sources with higher VOC emissions. If you must proceed, phase it in for two years. 

Response: All VOC emitting industries in our inventory have been included in our VOC reduction 

strategy. The rule has been revised to include a phase-in schedule. 

5.b.i - 199
DAQ-104-12 

Page 3 

4. There are definitions that are not in the rule. 

Response: A review of the rule did not locate unnecessary definitions. 

5. It is unusual to include language that provides a maximum VOC emission limit as the baseline for 

requiring the use of compliant products. Besides being very difficult to measure and manage, it can 

provide an undesired bias among local businesses. 

Response: VOC emission limits for coatings is not new. The current rule R307-340 has VOC 

emission limits for a number of industries. That rule has been in effect since the 1980s and has been 

implemented under another SIP. 

6. We believe the rule should simply apply based on geography, as in all other regulated regions. 

Response: This rule applies to the general population that should not be expected to understand the 

complex alignment of the total PM nonattainment areas. Since most of the population is located within 

the nonattainment boundaries, it is easier and more practical to apply it county wide. 

7. Exempt solvents were not included. 

Response: The rule limits VOCs, so by default, any solvent not defined as a VOC is not regulated. 

However, for clarity sake, it has been included. 

8. The rule should exempt aerosol coatings. 

Response: Agreed, the exemption has been added. 

9. The rule does not address the cleaning operation and any limits on cleaning products or processes. We 

believe aerosol based cleaning products, used in a non-atomizing manner, can significantly reduce the 

amount of solvent used (and VOC emitted) for cleaning spray guns and small repair areas. 

Response: Cleaning is included in R307-354-5(1)(f). The suggested alternate cleaning method requires 

the use of solvent with vapor pressure greater than the restriction in R307-354-5(1)(f) and in our 

opinion, would result in reduced surface exposure because the solvent would come out as a small 

stream. 

10. The applicability should be based on annual usage and not potential to emit (PTE) because operations 

are not continuous processes. 

Response: We recognize that operations are not continuous but the Clean Air Act regulatory structure 

is based on PTE. 

11. Sections R307-354-5(f) and (g) are redundant because the definition of non-enclosed paint gun cleaner 

requires a recirculating pump that provides the recycled solvent. 

Response: Agreed. Item (g) has been deleted.

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: Please see RACT analysis summary above. 

2. The rule threshold PTE for applicability is 2.7 tons per year or greater, where other state rules apply to 

all emissions within this this sector. 

Response: The SCAQMD rule was phased-in over a number of years permitting the industry to learn 

how to use water-borne coatings. The VOC limits we are proposing are a radical shift for the industry 

in Utah and will adversely impact small business if the applicability threshold is reduced to all emitters 

at this juncture. Even at this threshold, industry comments have been that they will suffer economic 

hardship because they are unable to pass on the added cost since their industry model depends on the 

insurance industry compensation program. 

3. The 90% control efficiency should be clarified whether it applies to the control device or the system. 

Other rules require 85% overall control and SCAQMD requires case-specific. 

Response: It applies to the device. System controls are better addressed in permits to assure facility 

specific design features consistent with the SCAQMD rule. 

4. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. Any facility sufficiently large that it would include an add-on control would require a permit. 

The permit will address the other items consistent with the SCAQMD rule requirement fashioned to 

address facility specific design. 

5. There are no VOC limits on cleaning solvents. 

Response: Gun cleaning must either be conducted in an enclosed system with a recirculating pump or 

a non-enclosed that also includes a recirculating pump, but an added requirement that the solvent must 

be less than 100 mm Hg at 68 degrees Fahrenheit. R307-335-7, Industrial Solvent Cleaning, would 

apply for additional cleaning operations that exceed 15 lb/day where more restrictive VOC limits exist. 

SCAQMD follows the same basic strategy. 

6. There is a lack of restrictions on manufacture and sale of noncompliant coatings, as well as labeling 

requirements. 

Response: Manufacturers are not constrained in manufacturing coatings with higher limits. This is not 

a statewide rule. Manufacturers produce a wide variety of products and those facilities who cannot 

substitute a product with a lower VOC content will have to use add-on controls. After all, the intent of 

offering an add-on control option is to permit use of higher material having a higher VOC content. 

The structure of this rule is the same as the current R307-340, Nonattainment and Maintenance Areas: 

Surface Coating, which has been approved by EPA in a prior SIP. Industry product labeling currently 

display the total VOC and exempt VOC content. PPG even goes further by providing detailed state 

limit information on their website and corresponding products that meet those limits.

7. The control efficiency (CE) value in the technical support document (TSD) of $2,740/ton is not 

verifiable. EPA’s CoST model lists a cost of $2,534/ton. 

Response: The CE in the TSD is not cost, it is control efficiency, as explained in the TSD. Cost was 

derived from AirControlNet page III-1317, than adjusted for current value (also explained in the TSD). 

Since current value can be calculated in varied ways, it is not surprising that there is a difference of 

$197. 

8. The rule effectiveness (RE) of 80% for Box Elder, Cache, Tooele, Utah, and Weber counties are not 

supported and lack documentation. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE; Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, DAQ applied the former 

EPA default RE of 80% that has been used in prior SIP’s. 

Staff Recommendation: Staff recommends the Board approve for final adoption of R307-354 as amended.

SUBJECT: FINAL ADOPTION: R307-355. Control of Emissions from Aerospace Manufacture and 

Rework Facilities. 

______________________________________________________________________________________ 

The purpose of R307-355 is to limit the emissions of volatile organic compounds (VOCs) from aerospace 

coatings and adhesives, from organic solvent cleaning, and from the storage and disposal of solvents and 

waste solvent materials associated with the use of aerospace coatings and adhesives. 

R307-355 was proposed as part of the PM2.5 State Implementation Plan (SIP). The reasonable available 

control technology (RACT) analysis process for this industrial sector was based on the following: 

1. The EPA control techniques guidelines (CTG), Control of Volatile Organic Compound Emissions 

from Coating Operations at Aerospace Manufacturing and Rework Operations, EPA-453/R-97-

004, December 1997. Area source CTGs are presumptive RACT, as explained on EPA’s website 

and the CTG itself (page 4-1). The CTG provides presumptive RACT coating limits for specialty 

coatings along with a model rule. The model rule includes some exemptions that were not adopted 

in the proposed rule in order to gain greater VOC reductions. We also chose to require higher 

control efficiency (95% instead of 81%) for add-on controls to increase VOC reductions. 

The CTG does not provide cost information. It is assumed that EPA developed a RACT model 

rule that meets the reasonableness test. However, DAQ proposed a more stringent rule than the 

model rule, therefore, DAQ requested cost information from industry during the public comment 

period to assess whether the proposed rule would meet the reasonableness test. ATK provided 

comments that two components of the proposed rule would add $1.4 million dollars of capitol cost 

to control a few tons of specific VOCs. Other commenters supported ATK’s comments without 

5.b.i - 209
DAQ-110-12 

Page 2 

providing cost information. They stated that EPA took great care working with industry to craft a 

RACT model rule that DAQ should follow. This matter is fully addressed in the detailed response 

to comments below. 

2. Review of the following aerospace rules: Missouri and San Joaquin Valley Air Pollution Control 

District (SJVAPCD). Both of these jurisdictions crafted their rules generally along the model rule. 

Both jurisdictions allow more exclusions than our proposal. Missouri requires 81% add-on control 

efficiency as per the model rule, while San Joaquin requires 95%. We attempted to gain cost 

information from these jurisdictions as well but none could be located. 

3. Direct stakeholder input from Boeing, ATK, Hill Air Force Base, and L-3 Communications. 

Boeing took the leadership role in representing the aerospace industry and worked closely with 

DAQ, sharing their established experiences from their operations and regulations in Missouri. 

Substantial enhancements were made for coating limits beyond the recommendations in the CTG 

based on input from Boeing that was beneficial in increasing VOC emission reductions. 

The proposed rule was released for public comment from October 1 to November 1, 2012. Comments 

were received from Boeing, Hill Air Force Base, ATK, American Coating Association, and EPA. Industry, 

as a whole, requested that we restore the exemptions left out of the model rule and lower the add-on control 

efficiency to 81% because of the dilution air that occurs when working in aircraft hangers. The following 

are responses to public comments. 

Industry Comments 

1. Three exemptions in R307-355-6(2) are not included that are recommended in the model rule. 

Response: Agreed. It was intended to be obvious that they would be exempt from the type of 

operations being conducted, with the exception of one category, specialty coatings, which should have 

been included. The adjustment has been made to include the three missing exemptions. 

2. The exemptions in R307-355-8, Solvent Cleaning, should be added as per the model rule. 

Response: Agreed. The section has been adjusted to match the model rule. 

3. Add-on control efficiency should be reduced to 81% per the CTG because large hanger air dilutes the 

VOC concentrations. 

Response: Agreed. The section has been adjusted to match the model rule. 

4. The rule applicability should be increased from 5 tons per year (tpy) to 25 tpy as per the CTG. 

Response: The model rule recommends a range of 10 to 25 tpy, depending on the nonattainment 

status. Missouri uses 25 tpy, while the SJVAPCD uses 4 gallons/day of the specific VOC containing 

material. The density of coatings will vary, so the threshold will range from about 5-6 tpy. We 

conducted a general “threshold equitability” review across all proposed coatings rules. Some rules are 

applicable as low as 2.7 tpy and others are as high as 25 tpy. Those with higher applicability, like 

graphics arts, have been reducing their VOC usage and reformulating due to federal regulations and 

often have practical industry specific limitations, similar to the considerations given to the aerospace 

industry. For the aerospace industry, this is reflected in the many exemptions in R307-355. When 

weighting the exemptions enjoyed by the aerospace industry with the challenge to meet attainment, 

applying the 5 tpy or greater threshold already in place in the San Joaquin Valley appears to present an 

5.b.i - 210
DAQ-110-12 

Page 3 

equitable threshold. Recognizing that 5 tpy may pose some technical challenges, we are 

recommending increasing the threshold to 10 tpy. 

5. The timeframe for enclosed gun cleaner repair should be increased from 48 hours to 15 days, as per the 

CTG. 

Response: The CTG does not explain the rationale for 15 days. We pursued further discussion with 

industry to understand the need for 15 days. Fifteen days is needed to obtaining purchase order 

approval in the military and parts for older booths can take longer to acquire. The timeframe has been 

changed to 15 days. 

6. Include rule exemptions for antique aircraft and space vehicles and their components as per the CTG. 

Response: Agreed. The base museum is faced with dealing with physical limitations and working 

with older coatings. The exemption has been adjusted to match the model rule. A definition for 

antique aircraft has been added. 

7. The VOC limits should be less exempt solvents. 

Response: Agreed. The rule specifies VOC, which by definition excludes non-VOC organic solvents; 

however, this has been clarified by adding the exemption and a definition of an exempt solvent. 

8. The rule should exempt aerospace equipment that is no longer operable and intended for public display 

as per the aerospace national emission standards for hazardous air pollutants (NESHAP). 

Response: The CTG includes an exemption for antique aircraft and components, which have been 

included in the rule. We believe that exemption is the same as what is being proposed by this 

comment. 

9. R307-355-6, Application Method, should be more descriptive along the lines of the CTG and include a 

Code of Federal Regulations (CFR) citation to define equal reduction to High Volume Low Pressure 

(HVLP). 

Response: Agreed. The application methods have been more fully defined. The CFR citation has 

been added. 

10. There is duplication between subsections 1 and 2 in R307-355-7, Work Practices and Recordkeeping. 

Response: Agreed. That was an insertion error and has been corrected. 

11. Permit the use of low vapor pressure hydrocarbon based solvents in R307-355-8, Solvent Cleaning, as 

per the aerospace NESHAP. Government contracts prohibit changing cleaning solvents. 

Response: Agreed. The cleaning options have been expanded. 

12. Allow cleaning of nozzle tips of automated spray equipment systems as per 40 CFR 63.744(c)(5), the 

NESHAP. 

Response: Agreed. R307-355-8 has been amended. 

5.b.i - 211
DAQ-110-12 

Page 4 

13. Add a definition for space vehicle. 

Response: Agreed. A definition has been added. 

14. The specialty coating definition referencing 40 CFR 63 subpart GG, Appendix A is insufficient to fully 

describe it. 

Response: Agreed. The definition has been revised per the recommendation. 

15. The add-on control device option, as worded, only applies to specialty coating. 

Response: Agreed. It was an oversight and has been corrected. 

16. There is a reference to Table 1 but that has been replaced with the CFR incorporation. Table 1 should 

be deleted. 

Response: Agreed and corrected. 

17. The rule should exempt operations that utilize a control device from HVLP spray gun requirements. 

Response: Add-on controls are intended to replace the use of coating limits. Transfer efficiency is a 

separate concern. No change is warranted. 

EPA Comments 

1. There is a lack of RACT analysis to determine rule requirements. 

Response: The RACT analysis is described above. The CTG clearly defines a model rule as RACT. 

We have gone beyond the model rule by working with industry to gain greater VOC reductions, even 

when we had added back some exemptions to the rule that were not originally proposed. 

2. Clarify that the 95% efficiency applies to the control device or the control system. 

Response: It applies to the device. 

3. The monitoring, recordkeeping, reporting and testing requirements are insufficient. 

Response: The recordkeeping requirement has been expanded to explain the types of necessary 

records. The owner/operator is required to provide documentation that the control system will attain 

the requirements of R307-354-6. This rule predominantly focuses on sources that require permitting. 

The facility permit will further provide site-specific system requirements. 

The model rule states that facilities that comply with the test method requirements of the aerospace 

NESHAP, 40 CRF 63.750 are deemed to be compliant with testing requirements. Since all of the 

facilities in question are expected to be subject to the NESHAP and the industry asked DAQ during the 

stakeholder process to avoid duplicability, we did not include testing requirements.

4. There are no VOC reductions shown in Table 6.5. 

Response: Correct. This rule was a late addition to the SIP and we were unable to include it in the 

attainment demonstration which would have provided the reduction information. It was, however, 

included in the technical support document (TSD) as a proposed rule. The SIP update will include 

reductions for this rule. 

5. The CTG states on page 5-1 that states should accurately describe the sources that would be affected 

and clearly define terms. There is no definition of “general aviation rework facility.” The primer and 

topcoat VOC limits are less stringent than those in the San Joaquin rule. 

Response: It is important to differentiate small repair/reworking operations that are referred to as 

general aviations from the large scale aerospace facilities. The definition for “general aviation rework 

facility” has been added, taken directly from 40 CFR 63. 

The primer and topcoat limits are identical to those in the San Joaquin rule for aerospace. The CTG 

(page 4-4) states that limits in the NESHAP can be applied but does not state what they are. The limits 

for general aviation were taken directly from the NESHAP, 40 CFR 63.745 Section c. 

6. The San Joaquin rule has more coating categories. 

Response: DAQ adopted the limits directly from 40 CFR 63 Subpart GG, as permitted per the CTG. 

7. The rule lacks capture efficiency. The San Joaquin rule requires 90% . 

Response: As pointed out by industry commenters, they operate in large hangers where the VOCs are 

diluted by the large air mass. Placing ridged capture efficiencies that cannot be attained is 

counterproductive. Missouri recognizes this by placing this requirement essentially in the hands of the 

permit writer: 

“Control equipment, including but not limited to incineration, carbon adsorption and condensation, 

with a capture system approved by the director, provided that the owner or operator 

demonstrates, in accordance with subsection (5)(C), that the control system has a VOC reduction 

efficiency of eighty-one percent (81%) or greater.” 

DAQ likewise believes capture efficiencies are appropriately addressed by permitting engineers who 

develop site specific requirements based on facility design and function. 

8. Work practices do not specify maximum VOC content for cleaning solvent. 

Response: Please refer to R307-355-8(1) – (2). 

9. The SIP TSD does not provide cost effectiveness value. 

Response: Correct. DAQ was unable to find a value, so we asked industry for that information during 

the public comment period. Industry has not provided that information. 

5.b.i - 213
DAQ-110-12 

Page 6 

10. The EPA CoST model indicates that cost effectiveness (CE) is actually higher than the 40% applied by 

DAQ. The actual CE is between 60-61%. 

Response: A definition for CE=control efficiency. DAQ will revise the CE to 60%. 

11. Rule effectiveness (RE) of 80% is not supported. 

Response: EPA directed DAQ to use the following EPA guidance in deriving RE: Attachment 2: NonPoint Source Rule Effectiveness Ranges, Emissions Inventory Guidance for Implementation of Ozone 

and Particulate Matter National Ambient Air Quality Standards and Regional Haze Regulations, EPA 

12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newly 

regulating an area, there is no enforcement history to reference; therefore, we applied the former EPA 

default RE of 80% that has been used in prior SIPs. 

Staff Recommendation: Staff recommends the Board adopt R307-355 as amended.

SUBJECT: FINAL ADOPTION: R307-356. Appliance Pilot Light. 

______________________________________________________________________________________ 

In order to reduce volatile organic compound emission, the Board approved for public comment a new rule 

for the State Implementation Plan (SIP) for PM2.5. The rule prohibits future sale and distribution of certain 

appliances with continuous pilot lights. 

The rule was posted in the Utah Bulletin for public comment from September 1 to October 1, 2012. 

Several hearth dealers and the national association representing the hearth industry submitted the same 

comment. Commenters requested that clarification be made that the rule applies to continuous pilot and 

not intermittent pilot ignition. Staff agreed with this recommendation. 

A public hearing was held on September 12, 2012. One hearth dealer presented the same concern 

identified in the public comment. 

Staff Recommendation: Staff recommends the Board approve R307-356 for final adoption as amended.

Estimated Cost 

According to AirControlNet, the 2005 cost was $1,032/ton (page III-1307) of VOC 

removal. The New Jersey Department of Environmental Protection conducted a detailed 

cost analysis in 2005 of the OTC rule and concluded that the cost was $2,300/ton. The 

current value for $2,300/ton based on the commodity real value method is $2,650/ton. 

The initial investments were borne by industry in earlier years to reformulate. Recurring 

costs are much lower; therefore, we can assume that the current cost for the proposed 

rule is around $3,000/ton. 

VOC Reduction 

The 1998 EPA rule and 2001 CARB rule implementations provided VOC reductions in 

consumer products nationwide. We have not adjusted our inventory to account for the 

impact of these rules; therefore, it is appropriate to take full credit for VOC reductions. 

The EPA database AirControlNet states that the VOC reduction for the CARB/OTC 

consumer products rules is 39.2% (page III-1307) based on a 2005 review. It also 

states that rule effectiveness and penetration are 100%, so no reductions should be 

made to the 39.2%. 

OTC has released model rule updates since the 2005 review which should be added to 

the 39.2%. The Mid-Atlantic Regional Air Management Association, Inc. retained SRA 

International in 2011 to evaluate the OTC model rules. SRA determined that there was 

an additional 2.0% VOC reduction and 3.3% VOC (4.8% if toxic ban is included) 

reduction for the 2006 and 2010 model rules, respectively, for a total of 44.5% (46% 

with toxic ban). 

5.b.i - 225
A current estimate of further reduction for the 2014 model rule is not available. The 

2014 rule includes first time limits for sanitizers/disinfectants, paint remover and paint 

thinner. Because OTC follows CARB’s lead, we consulted with the CARB Chief of Area 

Source and Emission Inventory regarding total VOC emissions for their consumer 

product rule. The Chief stated that she did not have a compilation of the total VOC 

reduction over the history of rule amendments, but speculated that it probably 

approaches 50%. If we assume a conservative 2% increased reduction, the total VOC 

reduction would be 46.5% (48% with toxic ban). 

Total VOC reduction – 48% distributed across the SCC’s per their percentage 

contribution to products listed in the rule.

Regulatory History 

EPA promulgated a national rule in 1998 (40 CFR, Part 59, Subpart C) for consumer products. The 

California Air Resources Board (CARB) and the Ozone Transport Commission (OTC) member states have 

periodically updated their state rules to obtain VOC reductions beyond those required by the federal rule. 

The OTC most current rule for 2014 includes limits for new categories and includes an optional prohibition 

on the use of chlorinated toxic compounds and ozone depleting compounds in certain consumer products. 

Stakeholders 

Advance notice of rulemaking was made to the national and local stakeholders. Staff worked 

collaboratively with the stakeholders to produce two optional rules: 

Option 1: Consumer products rule without a prohibition of toxics or an ozone depleting compounds ban. 

Option 2: Consumer products rule with both toxics and ozone depleting chemical bans. 

National stakeholders included: 

1. The Consumer Product Specialty Association (CSPA). According to CSPA, their membership 

accounts for 75% of the products manufactured that would be regulated by this rule. CSPA 

members are companies that engage in the manufacture, formulation, distribution, and sale of 

familiar consumer products. 

2. The Personal Care Products Council (PCPC) is the leading national trade association for the 

cosmetic and personal care products industry. 

3. American Coatings Association, Inc. (ACA) represents manufacturers of adhesives. 

While we do not believe that local manufacturers would likely be impacted by this rule, the Utah 

Manufacturers Association also received notice of advanced rulemaking as a precaution. 

Stakeholders Support 

Generally speaking, the CSPA, PCPC, and ACA have told us that they support the OTC model rule 

because it offers regulatory uniformity, permitting manufacturers to produce formulations that can be 

distributed nationally. In regard to Options 1 and 2, all three organizations are neutral on either option. 

VOC Reduction 

The 1998 EPA rule and 2001 CARB rule implementations provided VOC reductions in consumer products 

nationwide. We have not adjusted our inventory to account for the impact of these rules; therefore, it is 

appropriate to take full credit for VOC reductions. 

The EPA database AirControlNet states that the VOC reduction for the CARB/OTC consumer products 

rules is 39.2% (page III-1307) based on a 2005 review. It also states that rule effectiveness and penetration 

are 100%, so no reductions should be made to the 39.2%. 

OTC has released model rule updates since the 2005 review which should be added to the 39.2%. The 

Mid-Atlantic Regional Air Management Association, Inc. retained SRA International in 2011 to evaluate 

the OTC model rules. SRA determined that there was an additional 2.0% VOC reduction and 3.3% VOC 

5.b.i - 228

Page 3 

(4.8% if toxic ban is included) reduction for the 2006 and 2010 model rules, respectively, for a total of 

44.5% (46% with toxic ban). 

A current estimate of further reduction for the 2014 model rule is not available. The 2014 rule includes 

first time limits for sanitizers/disinfectants, paint remover, and paint thinner. Because OTC follows 

CARB’s lead, we consulted with the CARB Chief of Area Source and Emission Inventory regarding total 

VOC emissions for their consumer product rule. The Chief stated that she did not have a compilation of the 

total VOC reduction over the history of rule amendments, but speculated that it probably approaches 50%. 

If we assume a conservative 2% increased reduction, the total VOC reduction would be 46.5% (48% with 

toxic ban). 

Cost 

According to AirControlNet, the 2005 cost was $1,032/ton (page III-1307) of VOC removal. The New 

Jersey Department of Environmental Protection conducted a detailed cost analysis in 2005 of the OTC rule 

and concluded that the cost was $2,300/ton. The current value for $2,300/ton based on the commodity real 

value method is $2,650/ton. The initial investments were borne by industry in earlier years to reformulate. 

Recurring costs are much lower; therefore, we can assume that the current cost for the proposed rule is 

around $3,000/ton. 

Staff Recommendation: Staff recommends the Board propose for public comment R307-357, option 2 

because it provides the greatest degree of environmental protection.

Rule: R307-361. Architectural Coatings. 

Purpose 

The purpose of this rule is to limit volatile organic compounds (VOC) emissions from 

architectural coatings by specifying maximum VOC content limits and by creating 

storage, cleanup, and labeling requirements.

Applicability 

Counties: all nonattainment counties 

Threshold: applicable to any person who supplies, sells, offers for sale, applies, or 

solicits the application of any architectural coating or who manufactures, blends or 

repackages any architectural coating.

Estimated Cost 

According to AirControlNet, the initial cost for the OTC model rule was $6,628 per ton 

VOC reduced. Since most of that cost has already been realized in previous years, it is 

reasonable to assume that the cost to implement the OTC 2011 model rule will be 

substantially lower.

RACT Analysis Summary 

The California Air Resources Board (CARB) and various California air management 

districts implemented architectural and industrial maintenance (AIM) rules in the late 

1990’s-2000 based on reasonably available control technology (RACT) analysis. 

Updates to these rules have been made several times since their inception. EPA 

promulgated a national AIM rule in January 2005 (40 CFR Part 59 Subpart D). The 

Ozone Transport Commission (OTC) developed its first model AIM rule in 2001 based 

on the work conducted by CARB in 2000. The OTC most current rule is dated 2011. 

Several OTC member states plan on updating their rules to the most current OTC 

model rule in the near future.

SUBJECT: FINAL ADOPTION: R307-361. Architectural Coatings. 

_____________________________________________________________________________________

On June 5, 2013, the Board proposed for public comment R307-361, which is based on the Ozone 

Transport Commission (OTC) Phase II model rule. The public comment period was held from July 1 to 

July 31, 2013. 

The purpose of this rule is to limit volatile organic compound (VOC) emissions from architectural coatings 

by specifying maximum VOC content limits. 

The rule is applicable to any person who supplies, sells, offers for sale, applies, or solicits the application 

of any architectural coating or who manufactures, blends or repackages any architectural coating for use 

within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties. 

Summary of Substantive Public Comments

Air Quality Board Member Kathy Van Dame 

Kathy identified typographical errors in two equations and in a few paragraphs which have been 

corrected. 

American Coatings Association (ACA) 

1. The ACA requested an extension of the implementation date to January 1, 2015, to provide industry 

ample time to reformulate certain coatings.

Response: Staff concurs and has made the change. 

2. The sell-through date should be from the rule implementation date. 

Response: Staff concurs. R307-361-5(3) has been revised to include the implementation date and the 

language in that section has been simplified. 

3. Conversion Varnish should be added to the “Most Restrictive Limit Exemption” because, by 

definition, it is a wood coating that has a lower limit.

Response: Staff concurs and has made the change. This issue was raised to key OTC committee 

members to assure that OTC member states would agree. 

4. The proposed language in R307-361-5(6) would restrict the use of rust preventative coatings unless 

the rust preventative limit was identical to the industrial maintenance limit. Since the rust preventative 

and industrial maintenance limits are the same (250 g/l), this restriction is unnecessary. The ACA 

suggests that this provision be removed.

Response: Staff does not concur. The definition for industrial maintenance is broader and more 

complex than rust preventative. No change is necessary. 

Hill Air Force Base

1. Hill Air Force Base requested an exemption for military technical data specifications identical to the 

exemptions the Board has approved for previous industrial-based VOC-content rules (e.g., R307-342.

Adhesives and Sealants). 

Response: Staff concurs with this request and has modified the exemption request by recognizing that 

Department of Defense contractors should also be exempt when they perform contractor work that 

explicitly mandates the use of military technical data specifications. A definition for military data 

specifications and an exemption for operations that are exclusively covered by Department of Defense 

military technical date have been added. 

Staff Recommendation: Staff recommends the Board adopt R307-361, Architectural Coatings, as 

amended.

THROUGH: Bryce C. Bird, Executive Secretary

FROM: Joel Karmazyn, Environmental Scientist 

DATE: June 24, 2014 

SUBJECT: PROPOSE FOR PUBLIC COMMENT: Amend R307-335; R307-342 through 350; and 

R307-352 through 355. 

_____________________________________________________________________________________ 

The EPA has indicated its intention to approve the area source coatings rules for the PM2.5 State 

Implementation Plans as Reasonable Available Control Technology (RACT), but not until 1) they are 

amended to clarify that the amount of control removal specified in each rule is based on the entire system, 

and 2) the inspection and recordkeeping requirements for these systems are expanded. We have worked 

closely with EPA to craft agreeable rule language that is ready to be proposed for public comment. 

In each of the existing rules, with the exception of R307-335, the add-on control efficiency is based on the 

control device, rather than a system-based efficiency which EPA requires; therefore, these values have 

been amended in the proposed rules. The amended values are taken from the same EPA guidance 

documents or comparative RACT rules used during the initial RACT analysis, as described below for each 

rule. 

Advanced notice of rulemaking containing a draft of the Board memo and each rule was distributed to the 

Utah Manufacturers Association, the American Coatings Association, the local aerospace industry, and the 

Utah Auto Body Association. 

R307-335. Degreasing and Solvent Cleaning Operations. 

The emission control efficiency in this rule is already based on the overall system. EPA requested that we 

add the same testing and recordkeeping requirements inserted in the coating rules. 

R307-342. Adhesives and Sealants. 

The rule is based on the most current Ozone Transport Commission Model Rule which requires an overall 

capture and control efficiency of at least 85%. 

5.b.ii.A - 1
R307-343. Emissions Standards for Wood Furniture Manufacturing Operations. 

The RACT analysis was based on the EPA’s Control Technology Guideline (CTG) document, Control of 

Volatile Organic Compound Emissions from Wood Furniture Manufacturing Operations, EPA 453/R-96-

007, April 1996. The CTG provides a model rule but does not suggest a specific overall system efficiency 

value. 

The San Joaquin Valley Air District rule 4606 was selected for the RACT comparative analysis. That rule 

requires an overall system efficiency of 85%. We are proposing the same 85% requirement. 

R307-344. Paper, Film, and Foil Coatings. 

The RACT analysis was based on the CTG, Control Technologies Guidelines for Paper, Film, and Foil 

Coatings, EPA 453/R-07-003, September 2007. EPA developed the recommendations in the 2007 CTG 

after reviewing an earlier CTG, the new source performance standards (NSPS), and national emission 

standards for hazardous air pollutants (NESHAP). Because this CTG is a comprehensive document, we are 

proposing to apply the CTG-recommended 90% overall system efficiency. 

R307-345. Fabric and Vinyl Coatings. 

The EPA CTG for this industry is aged; therefore, we consider other state rules more appropriate for our 

RACT analysis. The San Joaquin Valley Air Pollution Control District rule 4607 is a comparable rule with 

a requirement of 90% overall system efficiency. 

R307-346. Metal Furniture Surface Coatings. 

The RACT analysis was based on the CTG, Control Technologies Guidelines for Metal Furniture 

Coatings, EPA 453/R-07-005, September 2007. This guidance document provides a presumptive RACT. 

EPA developed the recommendations in the 2007 CTG after reviewing an earlier CTG, the NSPS, and 

NESHAP. Because this CTG is a comprehensive document, we are proposing to apply the CTGrecommended 90% overall system efficiency. 

R307-347. Large Appliance Surface Coatings. 

The RACT analysis was based on the CTG, Control Technologies Guidelines for Large Appliance 

Coatings, EPA 453/R-07-004, September 2007. EPA developed the recommendations in the 2007 CTG 

after reviewing an earlier CTG, the NSPS and NESHAP. Because this CTG is a comprehensive document, 

we are proposing to apply the CTG-recommended 90% overall system efficiency. 

R307-348. Magnet Wire Coatings. 

There is no CTG that directly applies to this industry; therefore, we relied on the South Coast Air Quality 

Management District rule 1126 for our comparative RACT analysis. That rule requires an overall system 

efficiency of 90%. We are proposing the same 90% requirement. 

R307-349. Flat Wood Panel Coatings. 

The RACT analysis was based on the CTG, Control Technologies Guidelines for Flat Wood Paneling 

Coatings, EPA 453/R-06-004, September 2006. The CTG recommends an overall system efficiency of 

90%. 

R307-350. Miscellaneous Metal Parts and Products Coatings. 

The RACT analysis was based on the CTG, Control Technologies Guidelines for Miscellaneous Metal and 

Plastic Parts Coatings, EPA 453/R-08-003, September 2008. EPA developed the recommendations in the 

CTG based on a review of the former CTG, the 1988 NSPS, and the 2004 NESHAP. Because this CTG is 

a comprehensive document, we are proposing to apply the CTG-recommended 90% overall system 

efficiency. 

5.b.ii.A - 2
R307-352. Metal Container, Closure, and Coil Coatings. 

The RACT analysis was based on the CTG, Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles 

and Light-Duty Trucks, EPA 450/2-77-008. The CTG provided a comparative analysis of existing rules, 

and based on that analysis, we used the Bay Area Air Quality Management District Regulation 8, Rule 11 

as the primary reference source. The secondary source was Rule 1125 from the South Coast Air Quality 

Management District. We are proposing to apply the 90% requirement as per Regulation 8 Rule 11. 

R307-353. Plastic Parts Coatings. 

The RACT analysis was based on the CTG, Control Techniques Guidelines for 

Miscellaneous Metal and Plastic Parts Coatings (EPA 453/R-08-003, September 2008) which contains 

information on plastic coating. We are proposing to apply the CTG-recommended 90% overall system 

efficiency. 

R307-354. Automotive Refinishing Coatings. 

The RACT analysis was based on the CTG, Control Techniques Guideline for Reduction for Volatile 

Organic Compound Emissions from Automobile Refinishing (EPA 450/3-88-009, 1988/10) and the 

Alternative Control Techniques Document, Automotive Refinishing (EPA 453/R-94-031, 1994/04). These 

documents do not provide a system efficiency recommendation; therefore, we are proposing to use a 

reasonable efficiency level of 90%, which is near the expected level of reduction by applying low-VOC 

coatings. 

R307-355. Control of Emissions from Aerospace Manufacture and Rework Facilities. 

The CTG, Control of Volatile Organic Compound Emissions from Coating Operations at Aerospace 

manufacturing and rework Operations, EPA-453/R-97-004, December 1997, page B-8, provides a model 

rule with a system efficiency of at least 81%. The San Joaquin Valley Air District rule 4605 was selected 

for the RACT comparative analysis. That rule requires a system efficiency of 85%. The Missouri rule 

10CSR 10-5.295 was also used as a RACT comparative rule, and it requires the control system to reduce 

VOCs by 81%. Given the warehouse size operating areas common to these sources, it would be 

challenging at best to meet an efficiency value beyond 81%; therefore, we are proposing to apply the EPA 

guidance value and the Missouri RACT value of 81%. 

Staff Recommendation: Staff recommends the Board propose R307-335; R307-342 through 350; and 

R307-352 through 355 for public comment. 

5.b.ii.A - 3
1 R307. Environmental Quality, Air Quality.

2 R307-335. Degreasing and Solvent Cleaning Operations.

3 R307-335-1. Purpose.

4 The purpose of this rule is to limit volatile organic compound 

5 (VOC) emission from degreasing and solvent cleaning operations.

 6 

7 R307-335-2. Applicability.

8 R307-335 applies to all degreasing or solvent cleaning operations 

9 that use VOCs and that are located in PM10 and PM2.5 nonattainment 

10 and maintenance plan areas as defined in 40 CFR 81.345 (July 1, 2011).

 11 

12 R307-335-3. Definitions.

13 The following additional definitions apply to R307-335:

14 "Batch open top vapor degreasing" means the batch process of 

15 cleaning and removing grease and soils from metal surfaces by 

16 condensing hot solvent vapor on the colder metal parts.

17 "Cold cleaning" means the batch process of cleaning and removing 

18 soils from metal surfaces by spraying, brushing, flushing or immersing 

19 while maintaining the solvent below its boiling point.

20 "Conveyorized degreasing" means the continuous process of 

21 cleaning and removing greases and soils from metal surfaces by using 

22 either cold or vaporized solvents.

23 “Department of Defense military technical data” means a 

24 specification that specifies design requirements, such as materials 

25 to be used, how a requirement is to be achieved, or how an item is 

26 to be fabricated or constructed.

27 "Freeboard ratio" means the freeboard height (distance between 

28 solvent line and top of container)divided by the width of the 

29 degreaser.

TO: Air Quality Board 

THROUGH: Bryce C. Bird, Executive Secretary 

FROM: Joel Karmazyn, Environmental Scientist

DATE: September 15, 2014 

SUBJECT: FINAL ADOPTION: Amend R307-335, R307-342 through R307-350, and R307-352 

through R307-355. 

______________________________________________________________________________________ 

The EPA has indicated its intention to approve the area source coatings rules for the PM2.5 State

Implementation Plans as reasonable available control technology (RACT), but not until 1) they are

amended to clarify that the amount of control removal specified in each rule is based on the entire system, 

and 2) the inspection and recordkeeping requirements for these systems are expanded. DAQ has worked 

closely with EPA to craft agreeable rule language that was proposed for public comment by the Board on 

July 2, 2014. 

The public comment period was held from August 1 to September 2, 2014. 

We received a handful of verbal inquiries from manufacturers and distributors of solvent cleaners that

service the auto industry, asking why we do not permit the use of exempt solvents for cleaning in our rules. 

The definition of volatile organic compound (VOC) in R307-101-2 was adopted from 40 CFR 51.100(s)(1)

where the EPA has determined that certain compounds are exempt. Because we have adopted the EPA

definition by reference, we do permit the use of exempt compounds for cleaning, but we do not specifically 

state it in the rules. We are proposing to clarify this point in the rules by specifying that exempt

compounds are not VOC by definition. 

Cumberland Products, an automotive specialty products manufacture, further requested an interpretation on 

how to comply with an apparent conflict in the consumer product and automotive refinishing rules. The

automotive refinishing rule R307-354-5(1)(f), requires that spray gun cleaners have a maximum vapor

pressure of 100 mm Hg at 68 degrees Fahrenheit. The consumer products rule R307-357 defines a

consumer product as follows: 

195 North 1950 West • Salt Lake City, Utah 

Mailing Address: P.O. Box 144820 • Salt Lake City, Utah 84114-4820 

Telephone (801) 536-4000 • Fax (801) 536-4099 • T.D.D. (801) 536-4414

DAQ-084-14 

Page 2 

"Consumer product" means a chemically formulated product used by household and institutional

consumers including, but not limited to, .....and automotive specialty products but does not

include other paint products,...” 

The consumer products rule specifically identifies automotive specialty products as a consumer product. 

Cumberland Products distributes these specialty automotive products to the O'Reilly Auto Parts store chain 

where both general consumers and professional automotive personnel purchase their products. Some of

these products could have a VOC content that could potentially exceed 100 mm Hg at 68 degrees

Fahrenheit. In order to resolve this conflict, we are proposing to amend R307-354-5(1)(f) to exempt

products from the vapor pressure requirement that are specifically defined in R307-357. The products that

would be exempt from the vapor pressure requirement in R307-354-5(1)(f) will be required to meet the

VOC content limit(s) in the consumer product rule R307-357. We have extensively reviewed this rule

amendment with the Consumer Specialty Products Association’s senior director of strategic issues

advocacy and received concurrence on the proposed amendment from the American Coatings Association. 

EPA has been kept apprised of all the developments regarding the auto specialty products and has not

raised any objections to them. 

Staff Recommendation: Staff recommends the Board adopt R307-348 as proposed and R307-342 through 

R307-350 and R307-352 through R307-355 as amended.

Area Source Ammonia Reasonably Available Control Technology (RACT) 

EPA defines RACT as the lowest emission limitation that a particular source is 

capable of meeting by the application of control technology (i.e., devices, systems, 

process modification, or other apparatus or techniques that reduce air pollution) that 

is reasonably available considering technological and economic feasibility. 

This section provides a discussion on ammonia control strategies that are 

technologically feasible for winter-time manure management. Manure injection and soil 

incorporation (including chemical treatments prior to land application) are not included 

as manure management strategies because these activities cannot be performed when 

the ground is frozen. 

Ammonia Inventory 

There are many winter time source categories of ammonia within the nonattainment 

area source inventory. According to the non-point source 2011 national emissions 

inventory (NEI) for Utah, most of the sources are relatively small and less than 10% of 

the inventory can be attributed to these small sources. The smaller sources include 

human respiration, domestic animals, combustion of natural gas and wood burning, 

public wastewater treatment and consumer products. The remaining ammonia 

categories within the nonattainment area are attributed to wildlife (10%), such as deer 

and 79% from livestock and poultry. Within that 79% of the inventory; cattle (60%) and 

poultry (29%) are the largest ammonia sources. The remaining 11% is from 

miscellaneous livestock such as goats, sheep and horses. Consequently, the area 

source control strategy will focus on commercial cattle and poultry operations. 

Commercial poultry operations within 

the nonattainment area are limited to 

egg laying production. There are no 

commercial broiler operations or 

turkey growers. Ammonia emissions 

for the larger poultry operations can 

be calculated using the CAFO 

database and AP-42 factors. The four 

poultry CAFO operations within the 

nonattainment area are shown in the 

figure to the right. There are two in 

Utah County, one in Box Elder County 

and one in Cache County. 

5.b.iii - 1
Cattle operations within the 

nonattainment area include dairy and 

beef production. The cattle CAFO’s and 

their ammonia emissions are shown in 

the figure to the right. There are three 

sources in Utah County, two in Weber 

County, seven in Box Elder County and 

two in Cache County. 

Ammonia Characteristics in 

Manure 

Agriculture is responsible for over 

three-fourths of the ammonia emissions 

in the USA and Canada, with animal 

production accounting for the major 

share. Ammonia becomes a constituent 

of animal waste when nitrogen-rich 

protein in feed is not completely 

converted into animal products (such 

as meat, milk, wool, and eggs). For 

example, only 25 to 35% of the nitrogen 

fed to dairy cows is converted into milk, 

with the remainder excreted in urine 

and manure in a variety of simple and 

complex forms of nitrogen. Chemical and microbial processes release ammonia into the 

air. Nitrogen in poultry manure is mainly in the form of uric acid, which also rapidly 

converts to urea and to ammonia (Bittman and Mikkelsen, 2009). 

Ammonia is a colorless, lighter than air gas with a pungent odor. Significant 

volatilization of ammonia can occur within the first 24 hours after land application of 

manure. More than 50% of the total emission of ammonia can occur within the first six 

hours after application. Ammonia volatilization is highly dependent on manure 

management techniques and environmental factors, such as temperature and wind. 

Researchers have found that 50% of total nitrogen is volatilized as ammonia at a 

temperature of 30°C compared to 35% volatilization when the temperature is 25°C. 

Wind speed will increase the rate of ammonia volatilization as the higher wind increases 

the mass transfer and air exchange between the manured surface and the atmosphere. 

(AGRI-FACTS, Agdex 538-3, February 2008). 

Summary of Other State Rules 

A search was conducted of state rules designed to control agricultural ammonia 

sources. The following state rules have been identified: 

 South Coast Air Quality Management District (SCAQMD): Rule 1127 - Emission 

Reductions from Livestock Waste. The rule is intended to control ammonia, VOC, 

and PM10 from dairy farms and associated cattle operations, composting 

operations and anaerobic digesters. The rule requires the use of best 

management practices (BMPs) for manure collection, minimization of water 

usage in corrals, manure disposal, manure disposal, composting and feed stock 

preparation. Sources may propose alternative control options. 

5.b.iii - 2
 SCAQMD: Rule 1133.2 - Emission Reductions From Co-Composting Operations. 

The rule is intended to control ammonia and VOC from all co-composting 

operations. Co-composting is defined as composting where biosolids and/or 

manure are mixed with bulking agents to produce compost. Co-composting 

includes both the active and curing phases of the composting process. The rule 

requires that all active co-composting be confined within a controlled enclosure 

with a controlled vent that permits no more than 20% release by weight. 

 San Joaquin Valley Air Pollution Control District: Rule 4565 - Biosolids, Animal 

Manure, and Poultry Litter Operations. While this rule is intended to control VOC 

from operations involving the management of biosolids, animal manure, or 

poultry litter, certain provisions may also be helpful in controlling ammonia. This 

rule only applies to major sources whose throughput consists entirely or in part of 

biosolids, animal manure, or poultry litter and the operator who landfills, land 

applies, composts, or co-composts these materials. The requirements include 

operational constraints, the use of covers and 80% VOC control efficiency. 

 Idaho permit by rule for dairy farms (IDAPA 58.01.01): The rule applies to dairy 

farms with a capacity to produce 100 or more tons of ammonia emissions per 

year. The rule prescribes various BMPs to control ammonia emissions, ranging 

from installing certain types of waste storage and treatment systems to 

implementing composting practices to exporting manure. A point value is 

assigned to each BMP. Dairy farms must employ BMPs totaling 27 points. The 

Idaho BMP’s are in line with the control strategies discussed in the next section. 

Ammonia Control Strategies in Livestock and Poultry Manure 

Dietary Manipulations 

Excess nutrients not absorbed in the digestive tract are voided in the manure 

and urine. Dietary protein provides amino acids, nitrogen, sulfur, and other elements 

needed for animal reproduction, growth, and milk or egg production. Animals use less 

than half of the nitrogen that they consume, with the remaining excreted in the feces or 

urine. Fecal and urinary nitrogen are ammonia emission sources. Limiting crude protein 

levels in the diet to only that used by the animal limits nitrogen excreted in urea or uric 

acid, which contributes to emissions. 

While reducing crude protein content will reduce nitrogen excretion and ammonia 

emissions, reductions in crude protein can severely impact animal performance. To 

effectively reduce crude protein concentrations of diets for poultry, additional 

supplementation of synthetic amino acids is needed. Animals require a specific 

ratios of available amino acids; thus, lowering crude protein levels requires 

supplementation with select amino acids that otherwise would be insufficient. Specific 

synthetic amino acids can be added to meet the nutritional needs of an animal 

according to genetic lines, age, sex, and other factors (Air Quality Education in Animal 

Agriculture, January 2012). 

Research has shown that high-quality, protein-limited diets with appropriate 

supplementation of amino acids can effectively reduce nitrogen excretion and ammonia 

emissions from poultry, dairy and beef cattle operations without a loss in 

5.b.iii - 3
animal productivity. Commonly used amino acids are lysine, methionine, and threonine. 

Other amino acids may not be economically feasible (Applegate et al., 2008). 

Researchers have found that for every one percent reduction in crude protein, there is 

an 8.5-10% reduction in ammonia in dairy beef and poultry. Addition of fermentable 

carbohydrates (bran or pulp) results in a 14% ammonia reduction (Iowa State Univ. 

Extension, 2004). 

Undesirable sulfurous compounds often originate from sulfur-containing amino acids 

and sulfur-containing mineral sources. Limiting unnecessary sources of sulfur can 

reduce emissions of hydrogen sulfide and other volatile sulfur compounds (Air Quality 

Education in Animal Agriculture, January 2012). 

Ultimately producers formulate their own feed and may rely on feed ingredients based 

on lowest market cost that will result in acceptable yield. Supplementing diets with 

amino acids other than lysine, methionine, or threonine may not be economically 

feasible at this time. 

Dietary manipulation for the purposes of reducing ammonia production would require 

monitoring of a host of physiological factors, as well as monitoring feed ratio. Given the 

many complex variables, we cannot develop a universal SIP enforceable standard that 

would yield reliable control reduction while guaranteeing productive growth and/or yield. 

Consequently, dietary manipulation is screened out as a viable strategy. 

Manure Management 

Poultry Litter Amendments 

Poultry litter is a mixture of bedding materials, excrement, spilled food and feathers. 

Acidifying litter with aluminum sulfate (alum) creates an acidic condition in the litter that 

result in converting ammonia to ammonium sulfate. Additional benefits of alum 

amendment include phosphorous binding, killing pathogens, causes the birds to grow 

faster and assist in using feed more efficiently. Due to the benefits of this practice (and 

cost-effectiveness), over one billion broiler chickens are grown with alum each year. 

The United States Department of Agriculture (USDA) supports the use of alum 

amendment through some cost-sharing programs (direct communications with Philip 

Moore, USDA). 

Poultry manure treatment with alum in broiler houses has been demonstrated to reduce 

ammonia on average by 70% (Moore et al., 1999 and 2000). Alum is normally applied 

between each flock of birds at a rate of two tons of alum per broiler house. Alum costs 

about $250/ton (USDA, Treating Poultry Litter with Aluminum Sulfate (Alum)). 

Utah does not have commercial scale broiler houses but does have four large egg 

farms within the nonattainment counties. Given the successful use of alum in broiler 

houses, we explored the possibility of extending this control strategy for hen laying litter. 

According to Philip Moore of the USDA, there has only been one good study conducted 

by the USDA on the use of liquid alum in high-rise laying hen houses. An automated 

misting delivery system was built at an Arkansas operation at a cost of $30,000. The 

system delivered 1,000 gallons of liquid alum per month onto the litter at a cost of 

5.b.iii - 4
$440/month. System testing showed ammonia levels were reduced from 70-90 ppm to 

around 10 ppm. Ammonia flux was reduced by 33%. Moore noted that the study highrise house had higher than normal ammonia levels than one would find in newer highrise houses with better management practices. Consequently, the dramatic ammonia 

reduction in this study was attributable to the very high levels of ammonia at the study 

site. Feed conversion and egg production were improved with alum such that there was 

a net return of $426/week (excluding the capitol construction cost) (Moore et al., USDA 

grant report and direct communication). Moore stated during direct communications on 

this matter that he is not aware of any egg producer using an alum system.

This control strategy may be economically beneficial if a lower cost delivery system can 

be manufactured. At this juncture, there is no reliable data to support an expected 

control efficiency based on Moore’s commentary that the ammonia levels in the project 

house were above normal. In the absence of verifiable control efficiency data and cost, 

we cannot retain this control strategy for SIP inclusion. 

Mechanical Poultry Manure Processing 

Automatic manure belt systems are belts that travel on rollers under egg laying hens. 

The belts deliver the manure to the end of the cage row where manure cross conveyors 

remove it from the hen house to a manure storage area. The manure can be more 

readily disposed of or treated on a timely basis. According to one of the larger poultry 

producers in Cache County and a representative of the Utah Farm Bureau, poultry 

houses are preferably migrating to this expensive technology because removing the 

manure immediately after generation greatly reduces the fly population, rodents and 

odor. This mechanical process in itself does not reduce ammonia volatilization but it 

does collect the manure in a central storage area permitting timely treatment before 

large quantities of ammonia can evolve. 

Composting 

Ammonia loss during composting depends on the carbon to nitrogen (C:N) ratio. 

Ammonia volatilization is significant below a C:N of 15:1. Increased use of bedding 

(wood shavings, straw, etc.) helps maintain a higher C:N ratio. Application of a 

layer of 38% zeolite, placed on the surface of a composting poultry manure, reduced 

ammonia losses by 44%(Iowa State University Extension, July 2004). Composting 

requires routine pile mixing which would likely require amendment re-application. The 

cost for this control strategy is based on the amendment used and would be expected to 

be fairly low for carbon-based amendments like straw. One of the Cache County egg 

producers is currently composting his chicken litter with wood shaving and straw, then 

selling it commercially. A representative of the Utah Farm Bureau stated that producers 

are composting year round and that the piles generate enough heat to be effective even 

in winter. Since this strategy is already in common practice, there is no reason to 

consider it further in the SIP. 

Permeable Covers 

Permeable covers, or biocovers, act as biofilters on the top of manure storage areas. 

Materials often used as covers include straw, cornstalks, peat moss, foam, geotextile 

fabric, and Leka rock. Permeable biocovers reduce emissions, in part, by reducing both 

the radiation onto the manure storage surface and the wind velocity over the liquid 

surface of the storage area. At the solution/air interface, humidity is relatively high, 

5.b.iii - 5
which creates a stabilized boundary that slows the emission rate of odorous volatiles. 

The aerobic zone within the biocover allows the growth of aerobic microorganisms 

that utilize the carbon, nitrogen, and sulfur from the emissions for growth. By further 

degrading and making use of these compounds prior to exiting the biocover, odors 

emitted from the biocover are altered and reduced. Reports of odor reductions of 40-

50% are common whenever various straw materials are used. An odor reduction 

efficiency of 85% has been noted following the use of a floating mat or corrugated 

materials. Although ammonia emission reductions are undocumented, the processes

that occur in the biocovers suggest that ammonia emissions may be reduced to the 

same extent (Iowa State University Extension, July 2004). Cost would vary greatly, with 

the greatest cost for a geotextile fabric. 

Producers who practice composting are adding straw and wood shavings as the carbon 

source, essentially incorporating biocovers into their composting process. This control 

strategy is not retained for further consideration because it is already employed to some 

degree and there is no reliable data to support an expected control effectiveness value 

for ammonia. 

Liquid-Solid Manure Separation and Storage 

Because ammonia results from the interaction of urine and feces in ruminants, efforts to 

separate them immediately upon excretion have reduced ammonia emissions 

successfully (Iowa State University Extension, July 2004). The ammonia emissions 

reductions of urine-feces segregation in cattle has been reported to range from 21% 

with a 3% sloped solid floor collection (Braam et al., 1997a) to as much as 65% using a 

V-shaped pit floor with the gutter at the V (Braam et al., 1997b). A conveyor belt system 

was reported to reduce ammonia by 47-49% (Lachance et al., 2005; Stewart et al., 

2004). All reported studies show ammonia reduction. The limiting factor is the cost of 

installing a system, maintenance, and ease versus cost of operation. Most dairies within 

the nonattainment area may already be using some liquid-solid separation method. 

Given the structural complexity involved in installing these systems and the potential for 

high cost, we believe that this option is not well suited for SIP consideration, but should 

be encouraged as part of the USDA best management practices. 

Animal Housing-Biofilters and Scrubbers 

Biofiltration is a pollution control technique using living material contained on a fixed 

surface to capture and aerobically biologically degrade pollutants. 

P.M. Ndegwa, of Washington State University, presented a review of emission 

mitigation techniques at the Mitigating Air Emissions from Animal Feeding Operations 

Conference in 2008. He reported that the literature presents a broad range of biofilter 

efficiencies in the removal of ammonia in carrier-air from 9-100%. The variability was 

attributed to the wide range of biofilter-material, bed moisture, residence time, ammonia 

loading and bed biological activity. 

System cost in 2004 was reported to be $150—200 per 1,000 cfm of air treated. 

Operational cost was estimated at $0.25 per piglet, amortized over a 3-year for a 700-

head farrow-to-wean swine facility. Reductions of ammonia emission at that operation 

was approximately 74% (Iowa State University Extension, July 2004).

Biofiltration will only work when there is a complete air capture system in place which 

limits this application in the nonattainment area to egg laying producers, who as an 

industry, have chosen to move towards installing expensive mechanical belt manure 

removal systems. If we assume that half of the poultry operators have not converted to 

a mechanical belt system and if we assume that they contribute 50% of the ammonia 

within the poultry category, the 2011 NEI ammonia value would be 919 tpy. 

To determine the expected emission reduction, we must apply the following SIP based 

equation: 

Emission Reduction = [control efficiency (CE) x rule effectiveness (RE)] x rule 

 penetration (RP)] 

For the purposes of this analysis, we assume that CE equals 74% per the value 

reported by Iowa State. 

RE is a term that describes a method to account for the reality that not all facilities will 

comply with a rule that establishes a required control strategy. It also accounts for the 

fact that control equipment does not always operate at optimum control efficiency. A 

default value of 80% is used for new rulemaking. 

RP is a term that describes the extent to which a rule applies to a regulated population. 

In this case we assume 50% of the producers have not already converted to mechanical 

belt removal systems. 

Emission Reduction =((.74)(.80RE)) x (.50RP) = 30%

Emission Reduction = 919 tpy x 30% = 276 tpy 

The non-point source 2011 NEI total ammonia value for the nonattainment area is 

11,759 tpy. The 276 tpy emission reduction would amount to a 2% annual ammonia 

reduction or nearly zero on a daily basis. It is important to note that this scenario is an 

over-simplification, best-case estimate that does not reflect actual conditions because 

an accurate inventory of hen houses and their emissions has not been made. 

Ammonia sensitivity modeling indicates that it would require a 50% daily ammonia 

reduction in order to influence PM2.5 secondary formation. Consequently, the best-case 

projected ammonia daily reduction from hen houses is insignificant. Therefore, this 

control strategy is not retained for further consideration. 

Conclusion 

There are numerous complex factors involved in ammonia agricultural controls, 

complicated by winter-time conditions, which make it impractical to derive uniform air 

quality rulemaking. Further, ammonia reductions from prospective rules indicate that the 

ammonia reductions would be insignificant and would not contribute to the SIP process. 

The USDA has derived manure BMPs that it encourages producers to follow and it 

appears that the few states that regulate agricultural ammonia have applied these 

BMPs. As presented above, many producers are actively engaged in BMP practices 

and some have an economic incentive to manage their manure in such a way as to 

reduce ammonia evolution (less ammonia loss results in a higher grade fertilizer) 

because they sell their finished compost.
