Area Source Control Strategies

The area source RACT analysis consisted of a thorough review of the entire area source inventory for anthropocentrically derived direct PM 2.5 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

.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no longer represents current industry practice, we consider ed other state rules as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 show ed 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 minorsources 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.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 o f 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. Inspections 2009 2010 2011 2012 Totals

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 delegate d compliance program that incorporates all of the secondary considerations. The following provides examples of how the Ut ah 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 expand ed in newly regulated counties. This value is based on EPA’s past default value used in previous SIPs as a conservative approach

.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/m 3 PM 10 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 PM 2.5 woodburningcurtailment program requirements. R307-302 has been amended as part of this SIP to

include a much lower no burn action level of 25 μg/m 3 of PM 2.5 , with a contingency in the rule to lower it to 15 μg/m 3 . 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/m 3 , 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 PM 2.5 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 HealthDepartment 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 PM 2.5 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 theiropacity 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 . S ome sources initially had difficulty finding commercial
available s olvents 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 acatalyst 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 ha s 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

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.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/m 3 PM 10 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.

CMB Calculated Source Contributions Measured on February 14, 1996

Lindon, Utah

Source PM 10

Impact μg/m 3

Coke Oven 8.98

Blast Furnace 7.64

Automobile Tailpipe 0.60

Woodburning 7.12

Road Dust 53.79

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/m 3

. As the above table indicates, on the highest day measured in 1996, the CMB model estimated a wood burning impact of 7.12 μg/m 3

. The amount of reduction from 42.7 μg/m 3 in 1989 to 7.1 μg/m 3 in 1996, equates to a 83% reduction. This represents the amount of reduction in wood burning that actually occurred during the highestPM10 concentrations days from 1989 to 1996. Since the PM10 concentrations in the 1996 episode were above the 120 μg/m 3 level, 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/m 3 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/m 3 , the PM10 concentrations were in the 60 to 80 μg/m 3 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:

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 PM 2.5. 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 PM 10 and PM 2.5 areas. 2. The sole source registry will be re-opened because the expansion of the rule applicability. 3. The red-alert cut point for PM 2.5 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 PM 2.5. 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.DAQ-080-12 Page 2

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.R307-302 November 5, 2012 Page 1 of 3

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 contactwith 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 perweek 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.195 North 1950 West • Salt Lake City, Utah Mailing Address: P.O. Box 144820 • Salt Lake City, Utah 84114-48 20 Telephone (801) 536-4000 • Fax (801) 536-4099 • T.D.D. (801) 536- 4414

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 PM 2.5 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 adv ance notice of rulemaking. The Utah Restaurant Association was sent an advance copy of the propos ed 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 comm ent. 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 cata lyst with a control efficiency of 80%, we are confident th at the catalysts would perform at above 90% efficiency. On a chain-driven charbr oiler, 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 ExitDAQ-007-13 Page 2

estimated that 10% of the emissi ons 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 instal led and heated. In other words, an opacity reading is all that is necessary to determine if one is installed and ope rating correctly. Therefore, to resolve the Boards concern, we have amended the rule by remo ving 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 reducti on 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

__________________________________________________________________ ____________________

On September 5, 2012, as part of the PM 2.5 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 PM 2.5 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.DAQ-100-12 Page 2

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 PM 2.5 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 PM 2.5 emissions.

DAQ Response: Language has been added to include PM 2.5 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.R307-307 November 21, 2012 Page 1 of 2

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 appl icant 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.Reduction

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.

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 PM 2.5 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.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.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/m 3 . 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/m 3 differential when fugitive dust cannot be directly measured from a source? b. Assuming PM 10 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.DAQ-093-12 Page 4

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 PM 10 nonattainment area was designated, the entire Salt Lake County became nonattainment and the shift was made to secondary formation of PM 10 during wintertime inversions. Unpaved roads are not a significant contributor to PM 10 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.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 PM 2.5 and much less of PM 10 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.

### 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-AN010565 0018 -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.

### Existing Actual Emissions (from 2008 inventory) for the Hansen-Lehi Pit

PM10 PM2.5 SO2 NOx VOC CO NH3 Benzene Chlorine HCl

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.

### 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 suppressant s (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.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.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 require d to comply with R307-312 to reduce emissions by December 14, 2015.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.

### 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 1 st

to March 1 st ), 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.Results of Analysis

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

Nonattainment Areas.

______________________ ____________________ ____________________ _________________

Rule R307-312, Aggregate Processing Operations for PM 2.5 Nonattainment Areas, was proposed as part of

the PM 2.5 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 PM 2.5 emissions from the hot mix asphalt PM 2.5 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.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 PM 2.5 nonattainment or maintenance areas. The language in R307-312 was changed to the following: “PM 2.5 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 PM 2.5 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 PM 2.5 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.DAQ-102-12 Page 3

2) RACT for Hot Mix Asphalt Plants:

The RACT for Hot Mix Asphalt Plants does not adequately address PM 2.5 emissions and without adequate basis in the record, relies on an emission limit that is almost 20 years old.

DAQ Response – Stack testing for PM 2.5 has not been conducted in Utah for hot mix asphalt plants. Test methodology for condensable PM 2.5 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 PM 2.5 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” isDAQ-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) PM 10 SIP Conflict:

Parts of R307-312 may conflict with the Utah PM 10 SIP for Geneva Rock Products: Hansen Pit and

Mount Jordan Pit. The PM 10 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 PM 2.5 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 PM 10 SIP
for Geneva Rock Products. The PM 10 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 PM 10 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 PM 2.5 removed. Water application was estimated to cost only $651 per ton of PM 2.5 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.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 PM 2.5 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.

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 PM 2.5 nonattainment

areas and add a new section for industrial solvent cl eaning 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 tr eats 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 ma de 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 industr ial solvent cleaning section for areas already regulated under separate rules.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 t echnology 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 wa ste 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 Boar d adopt the amendments to R307-335.R3307-335 November 5, 2012 Page 1 of 5

6 **R307-335-2. Applicability.** 7
R307-335 applies to all degreasing or solvent cleaning operations 8 that use VOCs and that are located in PM10 and PM2.5 nonattainment 9 and maintenance plan areas as defined in 40 CFR 81.345 (July 1, 2011)[ 10 Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties]. 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 "Freeboard ratio" means the freeboard height (distance between 24 solvent line and top of container)divided by the width of the degreaser. 25 "Industrial solvent cleaning" means operations performed using 26 a liquid that contains any VOC, or combination of VOCs, which is used 27 to clean parts, tools, machinery, equipment and work areas. Cleaning 28 operations include, but are not limited to, spraying, wiping, [dipping, 29 ]flushing, and purging. 30 "Open top vapor degreaser" means the batch process of cleaning 31 and removing soils from metal surfaces by condensing low solvent vapor 32 on the colder metal parts. 33 "Separation operation" means any process that separates a mixture 34 of compounds and solvents into two or more components. Specific 35 mechanisms include extraction, centrifugation, filtration, and 36 crystallization. 37 "Solvent metal cleaning" means the process of cleaning soils from 38 metal surfaces by cold cleaning, open top vapor degreasers, or 39 conveyorized degreasing. 40

41 **R307-335-4. Cold Cleaning Facilities.** 42 No owner or operator shall operate a degreasing or solvent 43 cleaning operation unless conditions in R307-335-4(1) through (7) are 44

met. 45 (1) A cover shall be installed which shall remain closed except 46 during actual loading, unloading or handling of parts in cleaner. 47 The cover shall be designed so that it can be easily operated with 48 one hand if: 49 (a) The volatility of the solvent is greater than 2 kPa (15 mm 50 Hg or 0.3 psi) measured at 38 degrees C (100 degrees F), 51 (b) The solvent is agitated, or 52R3307-335 November 5, 2012 Page 2 of 5

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 tocommercial/industrial applications.

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 commercia l and industrial applicati ons. R307-342 applies to any person who manufactures, sells, supplies, or appli es 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 PM 2.5 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 sen t 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 suffi cient time for manufactures and suppliers to sell their existing inventory.

Advance notifications to major manufacturers outsi de the state will be made through the ACA.DAQ-004-13 Page 2

Reasonable Available Control Technology (RACT) Analysis

EPA issued the Control Techniques Guidelines (C TG) 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 analys is of existing state and local emission reduction approaches as follows.

In 1998, the California Air Resources Board issued a gui dance document for the industry that was based on eight existing California air pollution control district ru les. 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 reduc ing the availability of higher VOC content adhesives and sealants

within the nonattainment areas.

Variability Between CTG and OTC
CTG OTC Proposed Rule
Applicability threshold 5,475 lb./yr. 200 lb./yr. 200 lb./yr.

VOC reductions for cleaning materials Work practices –

no VOC limits Work practices and

VOC limits on cleaning materials Work practices

and VOC limits on cleaning materials
Product labeling None VOC content limits printed on product VOC content limits printed on product

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 th e 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% pl us 2% for the more stringent proposed rule for a
CE of 75%.

RE is a term that describes a method to account for the r eality 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 comp liance with the coating limits thereby simplifyingDAQ-004-13 Page 3

compliance. We normally apply an RE of 80% for ne w rulemaking; however, because this rule is based on national product development and delivery, an RE of 100% is applied (AirC ontrolNET 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 de velopment 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.

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 theapplicability 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.195 North 1950 West • Salt Lake City, Utah Mailing Address: P.O.

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 or ganic compound (VOC) emissions from wood furniture manufacturing.

The rule reduces VOCs by requiring ow ners and operators of wood furn iture manufacturing operations to use coatings with a VOC content established in the ru le 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 Co mpound 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 pub lic comment R307-350. The public comment period was held from October 1 to November 1, 2012. Pub lic 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 coa ting limits. We recognize that the CTG is dated, which is why we originally proposed to reduce the app licability from 25 tons per year (tpy) to 5 tpy. Upon re-evaluation of this rule and in comparison to othe r 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 reasonableDAQ-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 r ecommendation 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 a pplicability 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 recomm ended 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 ma nufacturing coatings and solvents with higher

limits. This is not a statewide rule. Manufactur ers 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.DAQ-113-12 Page 3

8. Cost control documentation is not verifiable.

Response: The cost for extending the current co ating limits was taken from the South Coast Air Quality Management District (SCAQMD) rule in 1996, $1,414 = $2,260/to n VOC removal in 2011

dollars.

9. Control efficiency (CE) documentation is lacking.

Response: The control efficiency was derived fro m 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 no t 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 Qua lity 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 applicab ility 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.R307-343 November 27, 2012 Page 1 of 6

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 forpaper 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 18.195 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

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.DAQ-108-12 Page 2

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.R307-344 November 26, 2012 Page 1 of 3

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.195 North 1950 West • Salt Lake City, Utah Mailing Address: P.O.

SUBJECT: FINAL ADOPTION: R307-345. Fabric and Vinyl Coatings.

_____________________________________________________________________________________

The purpose of this rule is to limit volatile orga nic compound (VOC) emissions from fabric and vinyl coating operations, which use roll, knife, or rotograv ure coaters and drying ovens. This rule replaces R307-

340-6.

The rule reduces VOCs by requiring ow ners 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, Pa per, 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 stat e 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 coa ting limits. EPA commented that the South Coast Air Quality Management Distri ct (SCAQMD) Rule 1128 and the San Joaquin Valley Air Pollution Control District (SJVAPCD) Rule 4607 lim its 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.DAQ-112-12 Page 2

On September 5, 2012, the Board proposed for pub lic comment R307-348. The public comment period was held from October 1 to November 1, 2012. Pub lic 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 am ended 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 effectivenes s are very different than what DAQ cited.

Response: DAQ derived its values from the CTG. Co st was adjusted to present value. EPA did not explain the reference used in CoST to estimate a variability of over $2,0 00/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 lo wer VOC control limits will increase cost and result in control efficiency increase. We will apply th e 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 no t 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 Qua lity Standards and Regional Haze Regulations, EPADAQ-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.

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

SUBJECT: FINAL ADOPTION: R307-346. Meta l 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 ow ners and operators of metal furnitu re surface coatings operations to use coatings with a VOC content established in the ru le 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 pub lic comment R307-348. The public comment period was held from October 1 to November 1, 2012. Pub lic 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.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 pe rmit, 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 contro l device. We believe that defining generic capture efficiency requirements in rules is counterproduc tive. 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 manuf acturing coatings with higher limits. This is not a statewide rule. Manufacturers produce a wide va riety of products and those facilities that cannot substitute for a product with a lower VOC content w ill 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 cu rrent 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 manufact ures’ 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 fro m 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/to n in 1990 dollars = $2,020/ton in 2011 VOC removal

is more realistic.

8. The rule effectiveness (RE) of 90% in Davis and Sa lt 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 OzoneDAQ-106-12 Page 3

and Particulate Matter National Ambient Air Qua lity 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 complia nce data for Davis and Salt Lake counties for the existing rule. That data shows that Range 1 of the guidance coul d be applied. We chose the lower value of 90% within Range 1 because we are tightening the contro l limits per the CTG, which will require timely response by sources within these counties.

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 be lieve 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 contro l efficiency. We believe that the cost would be more in line with $2,027/ton, especially with the a ddition 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 Sa lt 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 OzoneDAQ-105-12 Page 3

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,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.195 North 1950 West • Salt Lake City, Utah Mailing Address: P.O.

DATE: November 20, 2012

SUBJECT: FINAL ADOPTION: R307-348. Magnet Wire Coatings.

The purpose of this rule is to limit volatile organi c compound (VOC) emissions from ovens of magnet wire coating operations.

On September 5, 2012, the Board proposed for pub lic comment R307-348, which replaces the magnet wire coating section of R307-340.

The rule reduces VOCs by requiring ow ners and operators of coating ov ens to use coatings with a VOC content established in the rule, to use add-on contro ls 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 (Alternativ e 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 hazar dous 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 th e 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.DAQ-096-12 Page 2

We concluded that the current rule meets RACT objectives.

The public comment period was held from October 1 to N ovember 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 r ead “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 PM 10 and PM 2.5 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 b een added for Box Elder and Tooele counties.

4. The compliance schedule should be extended for thr ee years to accommodate those that may be newly regulated and have to add engineering controls. Response: Sources in Davis and Salt Lake counties ar e subject to this rule as of the effective date because the rule is the same as the requirements pres ently in R307-340-9. In other words, there is no change for those sources. A three year implem entation 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 requi rement 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 inform ation 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. Re quiring testing protocol for all area sources does not meet the economic reasonableness test. Any facility th at is sufficiently large to have add-on controls would require a permit, in which t esting and reporting are addressed.

4. No VOC limits on cleaning solvents are included. Response: We disagree. DAQ is proposing an indus trial cleaning rule (R307-335-7) that applies to all

industries that is the same as th e EPA reference to SCAQMD.

5. The rule does not include a capture effici ency 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 refinishin g rule includes this same provision because EPA recognizes that capture efficiency cannot always be standardized.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 fo r 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 Qua lity 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 histor y to reference, therefore, DAQ applied the former

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

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 theNESHAP 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.195 North 1950 West • Salt Lake City, U tah Mailing Address: P.O. Box 1448 2 0 • Salt Lake City, U tah 84114

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.DAQ -109-12

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. Th ere 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.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.R307-349 November 21 , 2012 Page 1 of 2

R307-350 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 newly regulated counties as a conservative

measure.RACT Analysis Summary

The 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 published in 1978. EPA published the new source performance standards (NSPS) in 1988 and an Alternate Control Techniques document in 1994. Further, EPA promulgated a NESHAP in 2004. EPA developed the recommendations in the 2008 CTG after reviewing the cited references.

DATE: November 26, 2012

SUBJECT: FINAL ADOPTION: R307-350. Miscellaneous Metal Parts and Products Coatings.

______________________________________________________________________________________

The purpose of this rule is to limit volatile orga nic compound (VOC) emissions from miscellaneous metal parts and products coati ng 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 Pa rts Coatings (CTG), EPA 453/R-08-003, September 2008. This guidance document provides a presumptive RACT. This CTG supersedes the original CTG published in 1978. EPA published th e new source performance standards (NSPS) in 1988 and an Alternate Control Techniques document in 1994. Further, EPA promulgated national emission standards for hazardous air pollutants (NESHAP) in 2004. EPA deve loped the recommendations in the 2008 CTG after reviewing the cited references.

On September 5, 2012, the Board proposed for pub lic comment R307-350. The public comment period was held from October 1 to November 1, 2012. Pub lic hearings were held on October 15, 16, and 17. Public comments were received from EPA, Nucor, Am erican Coatings Association, Boeing, Hill Air Force Base (HAFB), and ATK.DAQ-103-12 Page 2

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 t ons 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 c ontrol device. DAQ believes that defining generic capture efficiency requirements in rules is count erproductive. 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 rewo rded to exclude the director’s discretion, but retains the transfer efficiency requirement.

6. Cost control documentation is lacking and the 35% c ontrol 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 re ductions for VOC limits for cleaning solvents and we are adopting strict VOC limits for cleaning solv ents. 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 Sa lt 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 Qua lity Standards and Regional Haze Regulations, EPA 12/2005. That guidance bases RE on past enforcement history for the industry. When a rule is newlyDAQ-103-12 Page 3

regulating in an area, there is no enforcement histor y 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 complia nce data for Davis and Salt Lake counties for the existing rule. That data shows that Range 1 of the guidance coul d be applied. We chose the lower value of 90% within Range 1 because we are tightening the contro l 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 th e 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 b een 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 th at only the recommended work practices, but not the recommended VOC limits and application methods, a pply to the following types of coatings.” The rule is consistent with guidance. No change is warranted.

6. The implementation schedule should be delayed for th ree 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 typ es 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 tho se that were, in fact, in error were corrected.DAQ-103-12 Page 4

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 m unitions 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 covere d under miscellaneous metals. Our review indicates that exemptions in R307-350 should no t 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 di rectly from the recommendation within the CTG.

Staff Recommendation: Staff recommends the Board adopt R307-350 as amended.R307-350 November 26, 2012 Page 1 of 8

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.RACT Analysis Summary

SUBJECT: FINAL ADOPTION: R307-351. Graphic Arts.

______________________________________________________________________________________

The purpose of this rule is to limit volatile orga nic compound (VOC) emissions from printing operations. This rule replaces R307-340-12.

The rule reduces VOCs by requiring ow ners and operators to use coati ngs 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 finding s 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 c onsideration 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 an alysts have projected negative three percent industry growth for the next four years. At the same time, the industry NESHAP has spurredDAQ-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. Pub lic 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 R307-3 40-12 is 100 tons per year (tpy). Emission standards in the proposed rule have been re duced to 25 tpy, in keeping with the CTG recommendations. The applicability for work prac tices 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 “RAC T-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/to n, 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 reach es 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.DAQ-116-12 Page 3

5. Minimal number of limits on VOC content of clean ing solvents included. SJVUAPCD and SCAQMD specify a maximum that is lower than the 2006 CTG.

Response: Our industrial solvent cleaning requi rements 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 ru le 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 manuf acturing coatings with higher limits. This is not a statewide rule. Manufacturers produce a wide va riety 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 implementati on 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 a nd data sheets so that they can distribute their products nationwide.

7. Clarify why DAQ has chosen to use 90% control e fficiency for dryer emissions for all offset lithographic and letterpress printing when the 20 06 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 Qua lity 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 Da vis, 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 thres hold has been substantially lowered.DAQ-116-12 Page 4

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 de finition as to what ink is considered a solvent containing ink to differentiate specialty printing operations from flexographi c 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) shou ld 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 co ating 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 addr essed in the proposed rule in the definition for ‘printing operation.’DAQ-116-12 Page 5

10. The definition for “Flexographic Press” should be rem oved. It is it confusing and unnecessary as there is a definition for “Flexographic printing” which expl ains the printing process well enough for printing operations to determine which contro l requirements apply to them.

Response: We disagree. The definition of ‘flexogr aphic press,’ particularly the last sentence in the definition, serves as clarification of the units invol ved, 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 n ecessary 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 requirement s for fountain solution for heatset web offset lithographic operations of 1.6% alcohol or less (by we ight) 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 th e phrase “as applied” from subsections 2(a)(ii) and 2(a)(iii).

14. Subsection R307-351-6(2)(b)(i) includes requireme nts for fountain solution for sheetfed offset lithographic operations of 5.0% alcohol or less (by we ight) 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 operationa l 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 e qual.” 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.DAQ-116-12 Page 6

17. Remove the requirement to document device contro l efficiency in R307-351-8. Replace it with a requirement to operate the unit per the manufacturer recommendation.

Response: Emission control efficiency demons tration is necessary to show compliance. The provisions of R307-351-8 have been inserted in to each applicable standard subsection.

18. The implementation schedule requires compliance fo r 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 doc ument, 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 a pprove for final adoption R307-351 as amended.R307-351 November 27, 2012 Page 1 of 9

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.195 North 1950 West • Salt Lake City, Utah Mailing Address: P.O.

DATE: November 26, 2012

SUBJECT: FINAL ADOPTION: R307-352. Metal Contai ner, Closure, and Coil Coatings.

______________________________________________________________________________________

The purpose of this rule is to reduce volatile orga nic compound (VOC) emissions from the coating of metal coils, cans, pails, and lids.

The rule reduces VOCs by requiring ow ners and operators to use coati ngs 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, Pa per, 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 Manageme nt 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 pub lic comment R307-352. The public comment period was held from October 1 to November 1, 2012. Pub lic 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 corr ected by removing requirements for drums from this

rule.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, reporti ng 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 b een modified to define generic coating.

4. The applicability section does not include coil coating.

Response: The applicability section has been restructured. Coil coa ting 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 am ended 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 ma nufacturing 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 curre nt 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 manufact ures’ labeling indicates to us that major manufacturers already provide information on to to tal 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.DAQ-111-12 Page 3

10. The cost estimate for rule implementation is not verifiable.

Response: DAQ used the cost from the EPA datab ase 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 Qua lity 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.

THROUGH: Bryce C. Bird, Executive Secretary

FROM: Joel Karmazyn, Environmental Scientist

DATE: November 26, 2012

SUBJECT: PROPOSE FOR PUBLIC COMMENT: Change in Proposed Rule. R307-353. Plastic Part Coatings.

______________________________________________________________________________________

The purpose of this rule is to limit volatile organi c compound (VOC) emissions from plastic part coating lines. The rule reduces VOCs by requiring owners and ope rators of plastic part co atings 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 Pa rts Coatings (CTG), EPA 453/R-08-003, September 2008. This guidance document provides a presumptiv e 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 pub lic comment R307-350. The public comment period was held from October 1 to November 1, 2012. Pub lic 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.DAQ-107-12 Page 2

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 th e 90% efficiency applies to the c ontrol device or the control system. The overall control is not specified.

Response: The 90% efficiency applies to the contro l device. We believe that defining generic capture efficiency requirements in rules as counterproduc tive. 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 b een 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% c ontrol 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 stri ct 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 no t 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 OzoneDAQ-107-12 Page 3

and Particulate Matter National Ambient Air Qua lity 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).

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 PM 2.5 State Implementation Plan (SIP).

The reasonable available control technology (RAC T) analysis process was based on the following:

1. Two EPA-issued documents—Control Techniqu es 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) a pplies 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 strippi ng 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 ch loride. This does not apply to R307-354.

c. Spray guns to be High Volume, Low Pressure (H VLP), or electrostatic, air-assisted airless, or airless. Spray gun cleaning must be done in either an enclosed cleaning machine, byDAQ-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 pain t 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 la ter 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, docume ntation from the spray gun manufacturer proving the gun is an HVLP or otherwise permitted spray gun, and other requirements associated with methylene chloride use. A ll 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, a nd San Joaquin Valley Unified Air Pollution Control District (SJVU APCD) rule.

The proposed rule was released for public comment from Oc tober 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17. This propo sal 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 ru le will increase cost. The cost of equipment will go up, citing tens of thousands to hun dreds 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 c ontaining 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 forw ard 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 alread y 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.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 langua ge 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 othe r regulated regions.

Response: This rule applies to the general popula tion 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 th an 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 c ontinuous 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.DAQ-104-12 Page 4

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 th e applicability threshold is reduced to all emitters at this juncture. Even at this threshold, industr y 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 whethe r 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 cont rols 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 woul d 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 a nd sale of noncompliant co atings, as well as labeling requirements.

Response: Manufacturers are not constrained in manuf acturing coatings with higher limits. This is not a statewide rule. Manufacturers produce a wide va riety 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 cu rrent 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 corres ponding products that meet those limits.DAQ-104-12 Page 5

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 c ontrol 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 Qua lity 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 appr ove for final adoption of R307-354 as amended.R307-354 November 26, 2012 Page 1 of 5

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 PM 2.5 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), C ontrol of Volatile Organic Compound Emissions from Coating Operations at Aerospace Manufact uring and Rework Operations, EPA-453/R-97- 004, December 1997. Area source CTGs are presu mptive 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 withoutDAQ-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 ma tter is fully addressed in the detailed response

to comments below.

2. Review of the following aerospace rules: Miss ouri and San Joaquin Valley Air Pollution Control District (SJVAPCD). Both of these jurisdictions cr afted 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 Joa quin 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 thei r operations and regula tions 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 Novemb er 1, 2012. Comments were received from Boeing, Hill Air Force Base, ATK, Am erican Coating Association, and EPA. Industry, as a whole, requested that we restore the exemptions le ft out of the model rule and lower the add-on control efficiency to 81% because of the dilution air that o ccurs 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 obviou s 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 Cleani ng, 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 us es 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 acr oss 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, si milar to the considerations given to the aerospace industry. For the aerospace industry, this is refl ected 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 anDAQ-110-12 Page 3

equitable threshold. Recognizing that 5 tp y may pose some technical challenges, we are recommending increasing the threshold to 10 tpy.

5. The timeframe for enclosed gun cleaner repair s hould 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. Fift een 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 adju sted 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, whic h by definition excludes non-VOC organic solvents; however, this has been clarified by adding the exem ption 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 anti que 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 inser tion 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.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 th e 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 s ite-specific system requirements.

The model rule states that facilities that comply w ith 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 indu stry asked DAQ during the stakeholder process to avoid duplicability, we di d not include testing requirements.DAQ-110-12 Page 5

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 w ould 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 accurate ly 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 th an those in the San Joaquin rule.

Response: It is important to di fferentiate small repair/reworking op erations that are referred to as general aviations from the large scale aerospace faciliti es. The definition for “general aviation rework facility” has been added, taken directly from 40 CFR 63.

The primer and topcoat limits are identical to tho se 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. Th e 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 cap ture 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 appr opriately addressed by permitting engineers who develop site specific requirements base d 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.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 effici ency. 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 Qua lity 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.R307-355 November 26, 2012 Page 1 of 6

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 PM 2.5 . The rule prohibits future sale and distribution of certain appliances with continuous pilot lights.

The rule was posted in the Utah Bulletin for pub lic 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 a pprove R307-356 for final adoption as amended.R307-356 October 5, 2012 Page 1 of 2

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).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 re ductions beyond those required by the federal rule.

The OTC most current rule for 2014 includes limits fo r new categories and includes an optional prohibition on the use of chlorinated toxic compounds and ozone de pleting compounds in certain consumer products.

Stakeholders

Advance notice of rulemaking was made to the na tional and local stakeholders. Staff worked collaboratively with the stakeholders to produce two optional rules:

Option 1: Consumer products rule without a prohibiti on 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 manuf acture, 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. (A CA) 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 a ccount 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 re view which should be added to the 39.2%. The Mid-Atlantic Regional Air Management Association, In c. 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% VOCDAQ-012-13 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 mode l 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 Chie f 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 assu me that the current cost for the proposed rule is around $3,000/ton.

Staff Recommendation: Staff recommends the Boar d propose for public comment R307-357, option 2 because it provides the greatest degree of environmental protection.Rule: R307-3 61 . 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

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 implementa tion 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 th e use of rust preventative coatings unless the rust preventative limit was identical to the indust rial 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.R307-361 August 28, 2013 Page 1 of 24

SUBJECT: PROPOSE FOR PUBLIC COMMENT: Amend R307 -335; R307-342 through 350; and

R3 07-352 through 355.

_____________________________________________________________________________________

The EPA has indicated its intention to approve the area source coatings rules for the PM 2.5 State Implementation Plans as Reasonable Available Con trol 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 work ed 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 eac h

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. A dhesives and Sealants

. The rule is based on the most current Ozone Transport Commission Model Rule which requires an overall capture and con trol efficiency of at least 85%.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. F abric 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 presumpt ive 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 CTG

recommended 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 NS PS 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 b ased 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 wa s 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.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, Con trol 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. Auto motive 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%.

### 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.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 A ir

Quality Management District (SCAQMD) : R ule 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. SCAQMD : R ule 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.

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 appl ies 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 inanimal 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 manipulatio n 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 us ing 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$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 syste m.

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 Poult ry 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 r em oving 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, the n 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,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

wa s 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

a n 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 PM 2.5 secondary formation. Consequently, th e 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.
