DATE : January 2 1 , 2015
SUBJECT : Determination of Maximum Achievable Control Technology (MACT) for Specialty Coating Operations in the Aerospace Manufacturing and Rework Facilities Source Category

1.0 INTRODUCTION Section 112 of the Clean Air Act (CAA) requires the U.S. Environmental Protection Agency (EPA) to establish technology

- based standards for listed source categories. These technology

-based standards are often referred to as maximum achievable control technology (MACT) standards. The Aerospace NESHAP (40 CFR part 63, subpart GG) regulates hazardous air pollutant ( HAP ) emissions from facilities that are major sources of HAP and are engaged, either in part or in whole, in the manufacture or rework of commercial, civil, or military aerospace vehicles or components. Subpart GG currently requires the use of MACT to reduce HAP emissions from the following operations: cleaning; primer, topcoat and chemical milling maskant application; depainting; and waste storage and handling. The rule does not currently regulate the application of specialty coatings that are defined in Appendix A to subpart GG

. Subpart GG defines a specialty coating as a coating that, even though it meets the definition of a primer, topcoat, or self

- priming topcoat, has additional performance criteria beyond thos e of primers, topcoats, and self

- priming topcoats for specific applications. These performance criteria may include, but are not limited to, temperature or fire resistance, substrate compatibility, antireflection, temporary protection or marking, sealing, adhesively joining substrates, or enhanced corrosion protection. There are 59 separate categories of specialty coatings that are defined in Appendix A to subpart GG.

The EPA is proposing to now regulate specialty coatings based on MACT . EPA is proposing to us e the coating categories that are listed in Appendix A to subpart GG . These same coating categories are addressed in the control techniques guideline (CTG) document for aerospace manufacturing and rework (hereafter referred to as the Aerospace CTG). 1

### Section 112(d)(2) calls for the EPA to promulgate national technology

- based emission standards for each category or subcategory of sources that is listed in accordance with 112(c). For “major sources” that emit or have the potential to emit any single HAP at a rate of 10 tons or more per year or any combination of HAP at a rate of 25 tons or more per year, these technology

-based standards must reflect the maximum reductions of HAP achievable (after considering cost, energy requirements, and non

- air health and environmental impacts) and are commonly referred to as MACT standards. CAA section 112(d)(3) explicitly describes the minimum control level allowed for MACT standards

– that is the minimum control level that may be deemed the maximum degree of achievab le HAP reductions . The MACT floors for existing sources cannot be less stringent than the average emissions limitation achieved by the best performing 12 percent of sources in the category or subcategory (or by the best

- performing five sources for categori es or subcategories with fewer than 30 sources). For new sources, the MACT floor cannot be less stringent than the emission control that is achieved in practice by the best controlled similar source. In developing MACT standards, the EPA must also consider control options that are more stringent than the floor, commonly referred to as beyond

- the

- floor control options. The EPA may establish standards more stringent than the floor based on considerations of the cost of achieving the emissions reductions, any non
- air quality health and environmental impacts and energy requirements. Most aerospace coatings contain a mixture of organic solvents and/or inorganic HAP. The organic HAP emissions from the application of specialty coatings occurs from the evaporation of organic solvents during mixing, application, and drying. Emissions of inorganic HAP from spray

- applied coating operations, typically metal compounds (e.g., lead, chromium, or cadmium compounds), occur when paint particles do not adhere to the surface be ing coated (a.k.a., overspray). The organic and inorganic emissions from coating application occur in large open areas, such as hangars, or partially or fully enclosed spaces, such as within spray booths.
Section 2 .0 of this memorandum presents a summary of the sources of data that were used to conduct the MACT analysis and Section 3 .0 presents the MACT determination for specialty coating operations.

2.0 SOURCES OF AVAILABLE CONTROL TECHNOLOGY INFORMATION In order to identify the best performing sources, the EPA collected information on control technologies and the emission limitations achieved by facilities with specialty coating operations in the aerospace industry . The EPA consulted the following sources of data: the EPA’s RACT/BACT/LAER Clearinghouse, the California Statewide Best Available Control Technology (BACT) Clearinghouse, and regional and state regulations. In addition, as part of the risk and technology review (RTR) of the Aerospace NESHAP required by section 1 12(d)(6) of the CAA , the EPA sent out a comprehensive information collection request (ICR) to all known facilities in February 2011. The ICR requested information on material usage and control techniques used on all of the regulated and unregulated emissio n sources at aerospace facilities

.

2

### Responses to the ICR were received from 109 facilities using specialty coatings

. The ICR data represented almost 5,000 different applications of specialty coatings (i.e., the use of a separate specialty coating formulation at a separate aerospace facility).


### 2. 1 2011 ICR Data for Specialty Coatings Information from the 2011 ICR submittals was used to identify facilities with specialty coating operations. The data were reported on Form C

- 1, Coatings. Th ese coating data included total volume of coating for each formulation, physical property data (as

- applied), specialty coating type, HAP name, and HAP content and whether the coating was applied in a spray booth

. We applied the following filters to the C

- 1 data of the ICR to remove materials that were not specialty coatings :

• Removed materials that were reported in the survey responses that were already covered under subpart GG as primers, topcoats, or chemical milling maskants.

• Removed coatings that were not actually used (i.e., volume or coating usage was reported as zero)

.

• Removed facilities that were no longer in operation and facilities that were not actually subject to subpart GG. The ICR data represented about 6,300 individual specialty coating appl ications (the combination of a specific coating at an individual facility) at 109 facilities. In about 5, 2 00 cases, the specialty coating category was identified by the respondent; in the remaining cases the category was not identified and could not be determined from other reported information

. The majority of spray

- applied specialty coatings were applied in spray booths. The database of responses to the 2011 ICR was also reviewed to determine the technologies and practices reported by industry. Add

- on co ntrol devices for control of organic HAP emissions were reported, including thermal oxidizers and carbon adsorbers; however, these controls are not widely used in the source category for specialty coating operations. Add

- on controls were reported at only three facilities and for only eight types of specialty coatings. These controlled specialty coatings represented 23 reported applications of specialty coatings, out of about 5, 3 00 reported specialty coating applications (about 0.5 percent) and represented
o nly about 0.6 percent of the specialty coating gallons reported in the 2011 ICR.


### 2. 2 State and Regional Regulations In addition to the ICR data , we examined a variety of state and local regulations for aerospace surface coating operations , including the Maricopa County Air Quality Department in Arizona, the Connecticut Department of Energy and Environmental Protection, Delaware Department of Natural Resources and Environmental Control, Maryland Department of the Environment, Missouri Department of Natural Resources, Pennsylvania Department of Environmental Protection, Texas Commission on Environmental Quality, and in California the regulations for the San Diego, Bay Area, South Coast, and Eastern Kern Air Quality Management Districts (see Appendix 1 ). These regulations generally include specialty coating VOC emission limits in grams per liter of coating (less water and exempt compounds) for the specialty coating types based on the Aerospace CTG , which are summarized in Appendix 1

.

### 2. 3 RACT/BACT/LAER Clearinghouse Database Under the EPA's New Source Review (NSR) program, if a company is planning to build a new plant or modify an existing plant such that criteria air pollution emissions will increase by a certain amount, then the company must obtain an NSR permit. The NSR permit is a construction permit which generally requires the company to minimize air pollution emissions by changing the process to prevent air pollution and/or installing air pollution control equipment. The terms “RACT,” “BACT,” and “LAER” are acronyms for different program requirements relevant to the NSR program. RACT, or Reasonably Available Control Technology, is required on existing sources in areas that are not meeting national ambient air quality standards (non

- attainment areas). BACT, or Best Available Control Technology, is required on new or modified major sources in clean areas (attainment areas). LAER, or Lowest Achievable Emission Rate, is required on new or modified major sources in non

- attainment
areas.
BA CT and LAER (and sometimes RACT) are determined on a case

- by

- case basis, usually by State or local permitting agencies. The EPA established the RACT/BACT/LAER Clearinghouse, or RBLC, to provide a central data base of air pollution technology information (including past BACT and LAER decisions contained in NSR permits) to promote the sharing of information among permitting agencies and to aid in future case

- by

- case determinations. However, data in the RBLC are not limited to sources subject to RACT, BACT, and LAER requirements. Noteworthy prevention and control technology decisions and information may be included even if they are not related to past RACT, BACT, or LAER decisions. The RBLC contains over 5,000 air pollution control permit determinations that can help identify appropriate technologies to mitigate most air pollutant emission streams. It was designed to help permit applicants and reviewers make pollution prevention and control technology decisions for stationary air pollution sources, and include s data submitted by several U.S. territories and all 50 States on over 200 different air pollutants and 1,000 industrial processes. The RBLC provides several options for searching the permit database on

- line to locate applicable control technologies. On October 7, 2014 we conducted a search of RBLC entries for permits since 1980. We searched under the process code for Aerospace Surface Coating (41.001) which resulted in information on 32 facilities and 55 surface coating processes. The results are presented in Appendix 2 . Most of the processes relating to specialty coatings did not require a BACT review. Two facilities were identified using add

- on controls for surface coating of aircraft, but it is not clear whether these facilities were including specialty coating application in the controlled coating operations. One entry for the Boeing (Everett, WA) facility indicated high

volume, l ow
- pressure (HVLP), electrostatic airless and modified high

- efficiency air

- assisted airless spray equipment for corrosion inhibitor and sealing activities. A search using the keyword “Aerospace” resulted in 4 matching facilities, but these were already inc luded in the results using the process code for Aerospace Surface Coating. A search of the California’s Statewide BACT Clearinghouse yielded only a single result, which was also identified in the RBLC search described above.

4

### Finally, a search of Washington State’s records of permits for aerospace facilities identified a final Prevention of Significant Deterioration (PSD) permit dated September 10, 2014 , for the Boeing facility in Everett, WA

. 2 

### In this, the PSD permit considers BACT for VOC coating operations as complying with all applicable VOC emission standards of the Aerospace NESHAP. The accompanying technical support document identified add

- on control technologies, including a regenerative thermal oxidizer (RTO), but concluded these were not considered BACT after taking into account energy, environmental, and economic impacts. 3 

### This BACT analysis addressed all surface coating, and did not specifically address specialty coating operations.

3 .0 MACT FLOOR ANALYSIS FOR SPECIALTY COATIN G OPERATIONS 

### 3. 1 Using the 2011 ICR D ata The EPA considered a MACT analysis for specialty coatings based on the 2008 data that were submitted in response to the 2011 ICR. The EPA calculated the total organic HAP emissions from each specialty coating formulation taking into account the capture efficiency of the spray booth, if present, and the destruction or removal efficiency for any add

- on controls, if present. Refer to the memorandum “Aerospace Manufacturing and Rework Facilities RTR Modeling File Preparation,” November 2014, for more a more detailed description of the emission calculation procedures. The ICR data also included the mass of coatings solids from each specialty coating and the volume of each coating used. The EPA attempted to perform MACT floor rankings f or each specialty coating category, applying the criteria for MACT in section 112(d)(3), and summarized in section 1.0 of this
memo. From the organic HAP emissions and the mass solids and coating volume, the EPA was able to calculate the emission rate for each specialty coating in pounds ( lbs ) organic HAP per lb coating solids , and also in lb organic HAP per gallon coating. Unfortunately, the EPA determined that the specialty coating data submitted in the 2011 ICR were not of sufficient quality to perform a MACT analysis in this manner. The EPA determined that in many cases, the same coatings were classified by the reporting facilities into multiple different specialty coating categories , or the coating was simply identified as “specialty

. ” This indicated that the facilities did not carefully consider the specialty coating category definitions in Appendix A to subpart GG in selecting the specialty coating category to include in their ICR responses. The result is that the MACT floor for different categories could potentially be based on data from the same coating formulations, and those formulations would not be representative of the coatings that actually belong in those categories. About 5,000 specialty coatings formulations were reported in the ICR. The EPA did not have enough information from the ICR to resolve those cases where the same coating formulation was reported in multiple categories or reported as only “specialty.”

### However, the ICR data did allow EPA to investigate the feasibility of developing emission limits for specialty coatings using VOC content limits from the Aerospace CTG as surrogates for HAP content limits, similar to the approach used to regulate emissions f rom primers and topcoats. For each specialty coating category, the EPA calculated the industry

- wide weighted

- average HAP and volatile contents for the specialty coatings reported in the 2011 ICR

. The weighted

- average volatile and HAP contents were calculated for each category as the sum of the volatiles or the HAP fo r a category, divided by the sum of the liters reported for that category. The use of the industry

- wide weighted

- average for each specialty category minimized the effect of coatings that may have been mis

- categorized by the reporting facilities. The EPA
wa s not able to calculate the weighted

- average VOC content of each specialty coating category because VOC content was not reported in the ICR. Therefore, the EPA had to use the volatile content as a surrogate for the VOC content; in addition, the volatile co ntent could not be corrected for water content or exempt compounds. The EPA then plotted the average volatile contents and average HAP contents against the VOC content limits that are in the Aerospace CTG, and also plotted the HAP contents against the vol atile contents. In all three cases , there is a positive correlation : between the average volatile contents of the coating categories and the CTG VOC limits, between the average HAP contents per category and the CTG VOC limits, and between the average HAP content s and the average volatile content s per category. These positive correlations were present even though many of the specialty coatings are used at facilities that are not currently subject to VOC content limits for specialty coatings , and even though we have observed some errors in how coatings were categorized

. The EPA believes that the results of these comparisons of the weighted average HAP content and volatile content to the CTG VOC content limits for each specialty category reaffirms the relatio nship between HAP and VOC content for specialty coatings, and indicates that VOC content limits would be an appropriate basis for determining MACT for HAP content

. 

### 3. 2 Identified Control Measures for Specialty Coating Operations from RBLC and State Rules VOC emissions from specialty coating operations at aerospace manufacturing and rework facilities are addressed in the final Aerospace CTG document, which established presumptive RACT limits for VOC’s. The presumptive RACT limits for specialty coatings were based on the VOC limits contained in state VOC rules in California. We compared the state rule VOC limits for the aerospace industry to the VOC limits in the Aerospace CTG and identified several differences in the VOC content limits for certain sp ecialty coating categories. These differences generally affect about one

- quarter of the specialty coating categories (although each state or regional regulation may differ from the CTG in only a handful of categories), and the limits differ by less than 20 0 grams VOC per liter of coating. However, because of other differences between these state and regional rules and the Aerospace CTG, EPA has concluded that these differences in the VOC limits do not constitute more stringent emission limitations compared to the VOC limits in the Aerospace CTG. First, in many cases where a state rule has a lower VOC limit than the CTG, the state rule has also added coating categories with VOC limits equal to or higher than the CTG limits. For

6

### example, one state rule has a lower limit for fuel tank coatings, but has an additional category for “rapid cure” fuel tank coatings that is the same as the CTG VOC limit. In other cases, the state rule has different applicability from the Aerospace NESHAP or the CTG. For example, the South Coast Air Quality Management District, California, Rule 1124 does not apply the surface coating VOC limits to the recoating of assembled aircraft at rework facilities if the original coating formulation is used , The SCAQMD rule also includes exemptions for certain applications and low volumes of coatings that are not found in either the CTG or the Aerospace NESHAP. These differences in the categories and applicability minimize the effect of differences in the VOC content limits. Second, not all categories of specialty coatings are used at all Aerospace Manufacturing and Rework Facilities. For the specialty categories with more stringent VOC limits, the EPA does not have data to confirm that facilities exist in those jurisdiction s that are using those coatings and actually have to comply with the more stringent VOC limits. For example , regional rules established in Eastern Kern Air Pollution Control District, California and Maricopa County Air Quality, Arizona contain lower limits than the limits for several categories in the Aerospace CTG. However, the 2011 ICR data submitted by facilities in these two districts did not include formulations in these specialty categories; therefore, the EPA could not determine whether these more stringent limits in these two district rules were actually being achieved. The EPA would need to show that facilities are actually using coatings subject to these more stringent limits to confirm that these more stringent limits constitute the MACT floor acc ording to section 112(d)(3) of the CAA. Finally, many of the areas with more stringent VOC limits than in the CTG have climates that are warmer and drier than in most other parts of the United States, and this type of climate is more conducive to the use of low

- VOC coatings because it helps promote expeditious curing of the coatings under ambient conditions. In cooler and more humid areas, the coatings require the use of a solvent carrier and/or thermal curing. The Aerospace NESHAP and CTG, on the other h and, must establish HAP and VOC limits that are applicable across the United States. It is not practical to establish MACT limits for coatings based on regional climate differences for this
source c ategory.
The EPA did not have sufficient data to calculate the VOC emissions from the specialty coatings to determine whether the facilities were emitting at the levels of the VOC limits, or at a level below the VOC limits. Therefore, the EPA assumed facilities were emitting at the VOC limits of the specialty co ating categories for these comparisons. The review of state and local rules also identified several rules that require specialty coatings to be applied with the same high

- efficiency application methods that are required for primers and topcoats in subpart GG and that are also prescribed for primers and topcoats in the Aerospace CTG. This requirement is more stringent than the model rule found in the Aerospace CTG, which exempts specialty coatings from the requirement to use the high efficiency application methods that are specified for primers and topcoats. The use of high efficiency application methods for spray applied specialty coatings can achieve emission reductions through reduced coating consumption resulting from more efficient transfer of coating to the part with less coating overspray.

### 3. 3 MACT Floor and MACT for Organic HAP Emissions In place of using the ICR data to determine MACT for specialty coating operations, we based the MACT analysis on state VOC rules for specialty coating operations (using VOC as a surrogate for HAP) , and also considered the information collected from a review of the RBLC and state permitting databases

. Based on the state VOC rules and the other information sources considered, the MACT floor for aerospace manufacturing and rework specialty coating application operations is organic HAP content limits that are equivalent to the VOC content limits for specialty coatings included in the Aerospace CTG , which have been adopted by states to reduce emissions from specialty co ating operations in ozone non

- attainment areas

. This MACT determination is based on the fact that these VOC limits are currently being achieved by at least 12 percent of the operating facilities in a total population of 109 operating aerospace and rework facilities that reported using specialty coatings in the 2011 ICR. The facilities complying with the CTG limits for specialty coatings are located in ozone non

attainment areas where state VOC rules have been developed based on the Aerospace CTG , and the EPA does not have any information to indicate that facilities are achieving emission limitations lower than the required VOC limits

. Therefore, these VOC limits represent the MACT floor for specialty coatings. The EPA has not identified any achievable emis sion limitations more stringent than the MACT floor , or technologies that could be transferred and applied to specialty coatings operations . Therefore , the MACT for organic HAP emissions from specialty coatings is equal to the MACT floor limits based on th e Aerospace CTG for both new and existing operations

. In addition, we have identified the use of high

- efficiency application equipment for spray applied coatings as the MACT floor for specialty coating application operations. This determination is based on the fact that at least 11 facilities in California’s air pollution control districts are currently subject to district rules that require high

- efficiency application equipment for all coating operations, including specialty coatings. These 11 facilities represent 10 percent of the 109 facilities that reported using specialty coatings in the 2011 ICR , and the majority of the top 12 percent of facilities with specialty coating operations. ( In this case of coating application methods, the method required at the majority of facilities is taken as a measure of the central tendency in place of a numerical average.) Therefore, these 11 facilities constitute the MACT floor for specialty coatings application methods. We have not identified any control options more stringent than the use of high

- efficiency application methods for spray

- applied coating operations , so the MACT floor is also MACT for specialty coating application methods for both new and existing operations

. Based on the information from the 2011 ICR, the RBLC, and review of the state and local rules, we have not established that add

- on control techniques are feasible as MACT for specialty coating application operations for the aerospace industry. In the respo nses to the 2011 ICR, some facilities indicated that they employ the use of add

- on control devices to reduce organic HAP emissions (i.e., thermal oxidizers and carbon adsorbers) from surface coating operations, and may be using these controls for eight spe cialty coatings categories . However, these add

- on controls are not widely used in the source category and are used in only about 0.5 percent of specialty coating applications and for about 0.6 percent of coating gallons used

. At the facilities with add

- on controls, the controls are not used for all the reported specialty coatings at those

8

### facilities , and are not used for all of the specialty coatings within a category at a single facility. The EPA does not have enough data to reliably determine the emission limitation achieved by these facilities with the add

- on controls for the specific specialty coating categories. Also, as mentioned in section 2.1, the PSD review for the Boeing ( Everett , WA) facility did not consider add

- on control technologies, including RTO, as feasible for aerospace surface coating operations after taking into account energy, environmental, and economic impacts.
Where these add

- on controls are used for specialty coating operations, they are often used primarily to control other emissio n sources with higher emission concentrations in the exhaust, and may be used only for specialty coating operations as a secondary benefit. The EPA did not have facilities reporting the use of add

- on controls only for specialty coating operations without
o ther sources being controlled by the add

- on controls

. In the development of NESHAP for certain other surface coating source categories, the EPA had identified applications in which add

- on control technology wa s feasible for the reduction of HAP emissions. However, these situations are typically automated surface coating operations where the coating process can be totally enclosed and human coating applicators (such as spray gun operators in a spray booth) are not needed. 4 

### The ability to use a total enclosure allows for an emission stream with a relatively small volume and high HAP and VOC concentrations to be captured and sent to the add

- on control device. These conditions allow for more cost

- effective treatment of the stream because of the lower volume of the stream and the increased fuel value of the combustible HAP and VOC in the stream. The use of automated coating operations is not feasible for specialty surface coating in the aerospace industry because the size and variety of the parts being coated requires the use of human coating operators, and this means that HAP and VOC concentrations must be minimized to comply with worker safety standards. For these reasons, the EPA did not consider add

- on controls to be feasible as MACT for specialty coating op erations in the aerospace manufacturing and rework source category.


### 3. 4 MACT Floor and MACT for Inorganic HAP Emissions The MACT floor level for control of inorganic HAP emissions from spray
- applied specialty coating s is determined to be equivalent to the current requirements for control of inorganic HAP emissions from the spray application of primers and topcoats in the Aerospace NESHAP , as provided in 40 CFR 63.745(g). The predominant method used to control inorganic HAP emissions from all spray

- applied coating operations (including specialty coatings) is the use of a spray booth with a particulate filter to capture overspray particles that contain inorganic HAP as pigments . The Aerospace NESHAP currently requires the us e of spray booths with filters meeting minimum efficiency requirements for the spray application of primers and topcoats that contain inorganic HAP. ( 40 CFR 63.745(g)) Based on the results of the 2011 ICR, the EPA has determined that the vast majority of spray
- applied specialty coatings are currently applied in spray booths. It is likely that these specialty coatings are applied in the same spray booths as primers and topcoats, or at least

4 See, for example, 40 CFR 63, subpart KKKK, NESHAP for Metal Can Surface Coating, and subpart SSSS, NESHAP for Metal Coil Surface Coating.



### 9

### in spray booths that are very similar to those used for primer and topcoat operations. Therefore, the same inorganic HAP emission limitations that are applied to primer and topcoat operations
are also applicable to specialty coating operations , and these constitute the MACT floor for the control of inorganic HAP from speci alty coatings

. We have not identified any control options more stringent than the use of spray booths with high

- efficiency filters to control inorganic HAP emissions from spray

- applied specialty coating operations , so the MACT floor is also MACT for both n ew and existing operations

.
