National Emission Standards for Hazardous Air Pollutants: Surface Coating of Large Appliances

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

SUMMARY: This action promulgates national emission standards for hazardous air pollutants (NESHAP) for existing and new facilities that apply surface coatings to large appliances. These final standards implement section 112(d) of the Clean Air Act (CAA) which requires the Administrator to regulate emissions of hazardous air pollutants (HAP) listed in section 112(b) of the CAA. The intent of the standards is to protect the public by requiring new and existing major sources to control emissions to the level attainable by implementing the maximum achievable control technology (MACT).

Sources typically emit the following HAP: glycol ethers, methylene diphenyl diisocyanate, methyl ethyl ketone, toluene, and xylene. These compounds account for over 80 percent of the nationwide HAP emissions from this source category. These pollutants can cause reversible or irreversible toxic effects to people following exposure.

EFFECTIVE DATE: This rule is effective July 23, 2002. The incorporation by reference of certain publications listed in today's final rule is approved by the Director of the Federal Register as of July 23, 2002.

SUPPLEMENTARY INFORMATION:

Docket. The docket is an organized and complete file of all the information considered by EPA in the development of rulemaking. The docket is a dynamic file because material is added throughout the rulemaking process. The docketing system is intended to allow members of the public and industries involved to readily identify and locate documents so that they can effectively participate in the rulemaking process. The contents of the docket, including the BID for the proposed and promulgated standards and the EPA responses to significant comments will serve as the record in case of judicial review. (See section 307(d)(7)(A) of the CAA.) The regulatory text and other materials related to today's final rule are available for review in the docket, or copies may be mailed on request from the Air and Radiation Docket and Information Center by calling (202) 260-7548. A reasonable fee may be charged for copying docket materials. Worldwide Web (WWW). In addition to being available in the docket, an electronic copy of today's final rule will also be available on the WWW through the Technology Transfer Network (TTN). Following signature by the EPA Administrator, a copy of the final rule will be posted on the TTN's policy and guidance page for newly proposed or promulgated rules at http://www.epa.gov/ttn/oarpg. The TTN provides information and technology exchange in various areas of air pollution control. If more information regarding the TTN is needed, call the TTN HELP line at (919) 541-5384.

Regulated Entities. If your facility applies surface coatings to large appliance parts or products, you may be a regulated entity. Categories and entities potentially regulated by the final standards are shown in the following table. This table is slightly different from the table contained in the proposal preamble at 65 FR 81135. The changes made to the table between proposal and promulgation are the result of public comments. These changes clarify the types of facilities that will be affected by the promulgated standards.

[[Page 48255]]

As in the proposal, major sources classified under other NAICS codes will be subject to the standards if they perform large appliance surface coating operations and meet the other applicability criteria. Conversely, some facilities listed under these codes may not be affected because some of the codes in the table cover products that are not defined as large appliances for the purposes of the rule.

This table is not intended to be exhaustive, but rather provides a guide for entities likely to be regulated by this action. To determine whether your facility is subject to the rule, you should carefully examine the applicability criteria in Sec. 63.4081 of the rule. If you have questions regarding how this action applies to a particular entity, consult the appropriate EPA Regional Office representative.

Judicial Review. The NESHAP for large appliance surface coating operations was proposed on December 22, 2000 (65 FR 81134). Under section 307(b)(1) of the CAA, judicial review of NESHAP is available only by the filing of a petition for review in the U.S. Court of Appeals for the District of Columbia Circuit by September 23, 2002. Only those objections to the rule which were raised with reasonable specificity during the period for public comment may be raised during judicial review. Under section 307(b)(2) of the CAA, the requirements that are the subject of today's final rule may not be challenged later in civil or criminal proceedings brought by EPA to enforce the requirements.

1. Background

   1. What Is the Source of Authority for Development of NESHAP?

      Section 112 of the CAA requires us to list categories and subcategories of major sources and area sources of HAP and to establish NESHAP for the listed source categories and subcategories. The category of major sources covered by the final NESHAP was listed on July 16, 1992 (57 FR 31576) under the Surface Coating Processes industry group. Major sources of HAP are those that have the potential to emit considering controls, in the aggregate, 10 tons per year (tpy) or more of any HAP or 25 tpy or more of any combination of HAP.

   2. What Criteria Do We Use in the Development of NESHAP?

      Section 112 of the CAA requires that we establish NESHAP for the control of HAP from both existing and new major sources. The CAA requires the NESHAP to reflect the maximum degree of reduction in emissions of HAP that is achievable. This level of control is commonly referred to as the MACT.

      The MACT floor is the minimum control level allowed for NESHAP and is defined under section 112(d)(3) of the CAA. In essence, the MACT floor ensures that the standard is set at a level that assures that all major sources achieve the level of control at least as stringent as that already achieved by the better-controlled and lower-emitting sources in each source category or subcategory. 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. The MACT standards for existing sources can be less stringent than the standards for new sources, but they cannot be less stringent than the average emission limitation achieved by the best-performing 12 percent of existing sources in the category or subcategory (or the best performing five sources for categories or subcategories with fewer than 30 sources).

      In developing MACT, we also consider control options that are more stringent than the floor. We may establish standards more stringent than the floor based on consideration of the cost of achieving the emission reductions, any health and environmental impacts, and energy requirements.

2. What Changes and Clarifications Have We Made to the Proposed Standards?

   In response to public comments received on the proposed standards, we made several changes in developing the final rule. While some of the changes were designed to make our intentions clearer, other changes had a direct effect on the degree of coverage of the standards. The substantive comments and our responses and rule changes are summarized in the following sections. A more detailed summary can be found in the BID for the final rule which is available from several sources (see ADDRESSES).

   1. Scope of Source Category

      In the proposal, we defined the regulated community for the standards to be facilities that apply surface coatings to large appliances or components of large appliances. In the proposal BID and the table of regulated entities in the proposal preamble (65 FR 81135, December 22, 2000), we stated that the facilities are generally included under the following NAICS codes (and their SIC code equivalents): 335221 (3631) household cooking appliances, 335222 (3632) household refrigerator and home freezer, 335224 (3633) householdlaundry equipment manufacturing, 335228 (3639) other major household appliances, 333415 (3585) air-conditioning and warm air heating equipment and commercial and industrial refrigeration equipment, and 333319 (3589) service appliance. We cautioned that some facilities and products with these codes do not fit under the large appliance category, and similarly, there may be facilities under other codes that do in fact coat large appliances. Thus, these industrial codes were given as a guide but were not intended to be used as the only basis for determining applicability of the rule.

      The codes listed above are associated with household cooking equipment, refrigerators/freezers, laundry equipment, and floor vacuums and polishers, and various types of

      [[Page 48256]]

      commercial and industrial heating, ventilation, and refrigeration equipment. Table 2-1 in the proposal BID listed examples of large appliances that are produced by facilities in these categories.

      Several commenters stated that the scope of the category as proposed was overly broad and confusing. They felt that we had included several products not normally considered to be large appliances, and that these products should be regulated under the miscellaneous metal parts and products NESHAP currently under development. As an alternative, if EPA decided not to change the mix of products defined to be large appliances, one commenter suggested that we change the name of the source category to better match the product mix being represented.

      In addition, commenters asked for clarification on the applicability of the rule to certain coatings such as porcelain enamel, powder coatings, and asphalt interior soundproofing. The final rule clarifies that the aforementioned coatings are considered coatings for the purposes of the rule and will be subject to subpart NNNN. We also clarified that phosphating (a form of pretreatment) and metal plating are excluded as coatings in subpart NNNN.

      Our proposed definition of the large appliances source category was formed using the six SIC/NAICS codes as a foundation, and then including the products under those codes that we believed should be included as large appliances. Some commenters expressed confusion when comparing the preamble table to BID Table 2-1. We have clarified the scope of the source category by including definitions for large appliance product and large appliance part in the final rule. The definitions list the parts and products intended to be regulated under the final rule, and they supercede the listing in Table 2-1 of the proposal BID. We also modified the proposal preamble table and are including it in the BID for the final rule. We have added Commercial Laundry Equipment and have deleted Floor Waxing/Polishing and Motor Vehicle Air-Conditioning, in keeping with our intent at proposal. In addition, we have also deleted heat transfer coils and large commercial and industrial chillers from the table and from coverage by the large appliances NESHAP.

      A few commenters stated that the heat transfer coils used to cool fluids in refrigeration and air-conditioning systems typically have unique coating formulation requirements, and suitable coatings are not available in a low-HAP formulation. The need for special coatings arises from the complex geometry of heat transfer coils, as well as exposure requirements in food processing and other special environments. The coating information we collected and used to determine the MACT floor did not contain coatings used specifically for heat transfer coils. The commenters asked that this large appliance component be removed from the large appliances category and regulated under the miscellaneous metal parts and products NESHAP.

      We have examined the submitted data and arguments and have concluded that the data analyzed since proposal offer sufficient justification to revise the scope of the source category. Therefore, we have excluded heat transfer coils from coverage under the large appliances NESHAP.

      A trade organization and one manufacturer of large commercial and industrial chillers (equipment that produces chilled water for use in a number of industrial processes including heating, ventilating, and air conditioning (HVAC) applications) commented that large chillers are very different from other products included as large appliances. They said that large HVAC products are produced in much lower volumes than white goods and are often custom designed. Furthermore, they are often subjected to outdoor environments requiring that they meet strict performance criteria, and they have a longer expected life. Commercial and industrial chillers are much larger than most other large appliances and are painted after assembly. Therefore, they cannot be put through a baking oven to cure the coatings, which restricts the coatings available for use.

      We requested additional supporting data on large chiller equipment coating operations and the available coatings. We also visited one of the few facilities that manufactures that equipment. Our evaluation of the chiller coating operations led us to determine that large commercial and industrial chillers should be excluded from the Large Appliances category for the reasons described by the commenter.

   2. Definitions

      We have added definitions for large appliance product and large appliance part to the final rule. These definitions include ``white goods'' appliances, as well as certain HVAC equipment used in commercial and industrial applications. However, specifically excluded from the definition of large appliance product are heat transfer coils, large commercial and industrial chillers, and motor vehicle air- conditioning units.

      We added several other new definitions in response to comments and to increase the clarity of the rule. Newly defined terms include adhesive, facility maintenance, heat transfer coil, large commercial and industrial chillers, and month. Clarifying changes were also made to the proposed definitions for coating operation, manufacturer's formulation data, and surface preparation.

   3. Overlap With Other NESHAP Categories

      Several commenters requested that the final rule provide compliance flexibility for facilities that coat a variety of items in addition to large appliances or large appliance components. Such facilities may be affected by several coating NESHAP, such as the standards for large appliances, miscellaneous metal parts and products, and plastic parts and products. They sought a regulatory approach that would allow facilities to opt specific coating operations or product lines, that are collateral to large appliance coating operations, out of the rule and into either the miscellaneous metal parts and products rule under development or the plastic parts and products rule that is also under development. Commenters also believed that plants coating types of items with a wider use beyond large appliances (such as motors, handles, hinges, etc.) should have the choice of those operations being covered by either the miscellaneous metal or plastic parts rule, even if the specific items are designed to be used on large appliances.

      We understand that many facilities may find it beneficial to consolidate their regulatory coverage for a number of different types of coating operations (such as large appliances, miscellaneous metal parts, and plastic parts) into a single NESHAP. Consolidation may reduce the amount of records, reports, or compliance calculations that the facility would have to maintain. To address the issue of multiple regulatory coverage, we are including a new provision in the final rule that allows the consolidation sought by the commenters. Under this approach, as an alternative to complying separately with multiple coating NESHAP, a facility may choose to be subject to the requirements of only one applicable NESHAP, provided it is the most stringent of the applicable subparts. The test for stringency is a demonstration that the facilitywide HAP emissions from all surface coating operations will be less than or equal to the emissions achieved by complying separately with

      [[Page 48257]]

      all applicable subparts of 40 CFR part 63.

      There are many facilities that apply surface coatings to a variety of items that may be used on large appliances, but which also have application to other types of products. We agree that such multi- purpose items are not exclusively large appliance parts and may be considered more appropriately miscellaneous metal parts or plastic parts. Therefore, we are excluding these items from coverage under the final rule. However, if a large appliance source prefers to have all its coating operations subject to only one coating NESHAP to consolidate recordkeeping and reporting requirements, the source would have the option described above of complying with only the most stringent applicable NESHAP.

   4. Other Changes and Clarifications

      A number of commenters found the proposed compliance options confusing and some suggested variations on the way these options should be applied.

      One of the commenters believed that the calculations, monthly compliance determinations, and recordkeeping required under the compliant material option should not apply to coating operations that use only powder coatings that contain no HAP. The commenter suggested relevant portions of the proposed requirements that he believed should not be applicable to these powder coating operations.

      We have reviewed the proposed calculations, compliance determinations, and recordkeeping requirements for the compliant material option and believe the commenter identified a need to clarify the rule language. The proposed language would have required an affected source choosing the compliant material option and using only powder coatings and non-HAP cleaning materials to determine the mass fraction of organic HAP, the volume fraction of solids, and the density for each coating, and then to determine the ratio of organic HAP to coating solids. Records and certain reports would have had to include such calculations. We did not intend to require this unnecessary calculation for non-HAP coatings at proposal. Clearly, if a coating contains no organic HAP, it is not useful to record and report such calculations since the result is obviously zero kilogram (kg) organic HAP per liter of coating solids. Therefore, we have added a provision in Sec. 63.4141(a) and (d) of the final rule specifying that if the mass fraction of organic HAP in a coating is zero, as determined according to Sec. 63.4141(a) (through test results or manufacturer's formulation data), then the source is not required to determine the volume fraction of coating solids and density or to calculate the organic HAP content. This new provision applies to all types of coatings that contain no organic HAP, not just powder coatings. For such a coating, Sec. 63.4141(d) of the final rule specifies that the organic HAP content equals zero and no calculation is required. The following notification, reporting, and recordkeeping sections of the rule were also revised to fully incorporate this provision: Secs. 63.4110(b)(8) and (b)(8)(i), 63.4120(d)(2), and 63.4130(c), (c)(1), (f), and (g). We believe that these changes are responsive to the commenter's concerns, and that they retain only the requirements that are essential for compliance and enforcement purposes.

      Some commenters asked whether different compliance options could be combined for the same coating operation in order for sources to gain more flexibility in the way coatings and other materials are used in an operation. We proposed three compliance options: Option 1 when using compliant materials, Option 2 when determining emission rate without add-on controls, and Option 3 when using emission controls. The three proposed compliance options address different situations and were intended to be applied on a one-at-a-time basis (see Sec. 63.4091 introductory language). Both Options 1 and 2 cannot logically be used on one coating operation at the same time. If all coatings meet the limit and all thinners and cleaners are HAP-free, then Option 1 could be used and, thus, there would be no need to combine data elements for multiple coatings, thinners, and cleaning materials to derive an emission rate (required for Option 2). If the coatings, thinners, and cleaning materials do not meet the Option 1 criteria, or if the source owner or operator chooses not to use Option 1, then Option 2 must be used (or Option 3 if an add-on control device is in use). In no case may coatings, thinners, and cleaning materials accounted for under one option be included in the accounting under another option. Because the compliance options are designed to accommodate different situations and, due to the lack of compelling information or justification for the commenter's suggested rule change, the final compliance option provisions are the same as proposed.

      Additionally, one commenter believed that a clarification was needed for proposed Sec. 63.4081(a)(3), which excluded certain categories of surface coating from coverage by the rule, such as facility maintenance operations. The commenter wanted the rule to make specific mention of the paint booths that are used for maintaining manufacturing equipment. We agree with the commenter that the rule should not apply to paint booths or to other surface coating equipment used exclusively to coat something other than large appliances. If, however, the paint booth or equipment is sometimes used for large appliance surface coating, it would be subject to the standards during those times and would need to be considered part of the affected source. It also is subject to the standards if it is used for cleaning of equipment used in coating operations, e.g., application equipment, hangers, and racks (see Sec. 63.4081(c)(6) and the definition of coating operation in Sec. 63.4181). To clarify our intent, we have included the following definition of facility maintenance in the final rule: Facility maintenance means the routine repair or refurbishing (including surface coating) of the tools, equipment, machinery, and structures that comprise the infrastructure of a facility or that are necessary for the facility to function in its intended capacity. It does not mean cleaning of equipment that is part of a large appliances coating operation.

      One commenter suggested that EPA establish a low-use exemption threshold for military installations where military members could apply coatings at on-base hobby shops and housing areas to repair personally owned appliances. Generally, in hobby shops, the prevailing coating application would involve hand-held, non-refillable aerosol containers. However, individuals using hobby shop facilities may also apply the coatings by methods other than hand-held aerosol cans. In the proposal, we excluded hand-held aerosol container coatings from the rule but did not exclude other coating application methods, specifically those related to hobby shops. However, in considering this comment, we concluded that coating application by individuals who repair, refurbish, or recoat large appliances or other types of products at military hobby shops or base housing areas does not compare to the coating operations conducted at facilities that apply coatings as a step in the production of large appliances. Therefore, these coating activities are not subject to the standards. We believe that expanding the exclusion in Sec. 63.4081(d)(4) to include hobby shops is a more appropriate way to address this issue than creating a low-use exemption that would necessitate coating usage recordkeeping at the hobby shop. Therefore, Sec. 63.4081(d)(4) of the final rule excludes research or

      [[Page 48258]]

      laboratory facilities; janitorial, building, and facility maintenance operations; hobby shops operated for non-commercial purposes; and the use of hand-held, non-refillable aerosol containers.

      In addition to the changes described above, we noted several areas of the proposed rule that warrant revision even though commenters did not object to them. The changes are necessary so that the provisions properly reflect our intent and are consistent with other surface coating NESHAP under development. As proposed, Sec. 63.4100(a)(2) indicated that affected sources using the emission rate with add-on controls options would not have to comply with the standards during periods of startup, shutdown, and malfunction. This provision is often found in NESHAP in which compliance with the standards is based solely on the results of a short-term initial performance test and short-term averaging of continuous monitoring results thereafter. After proposal of the large applicances NESHAP, we realized that this provision is not appropriate for the surface coating NESHAP when these short-term test and monitoring results are only one component of a compliance determination that determines emissions over a long period of time, which in this case is a month. For the large appliances NESHAP, the source owner or operator will use the performance test and continuous monitoring results in combination with data on coatings and other materials used over a month's period of time. These components will be combined to calculate a monthly organic HAP emission rate. Since there may be many startups and shutdowns of a coating operation over the course of a month as part of normal operation, it is not appropriate to exempt such periods from compliance with the standards. The rule does require in Sec. 63.4100(d) that you develop and operate according to a startup, shutdown, and malfunction plan, and Sec. 63.6163(h) provides the following: ``Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that occur during a period of startup, shutdown, or malfunction of the emission capture system, add-on control device, or coating operation that may affect emission capture or control device efficiency are not violations if you demonstrate to the Administrator's satisfaction that you were operating in accordance with the startup, shutdown, and malfunction plan. The Administrator will determine whether deviations that occur during a period of startup, shutdown, or malfunction are violations according to the provisions in Sec. 63.6(e).'' We believe that this provision along with a month-long compliance period that will accommodate potential short-term higher emission rates that might occur due to startup, shutdown, or malfunction are adequate and that the proposed exemption is not necessary or appropriate. Therefore, it is not included in the final standards.

      Another change we made to the rule is intended to simplify the compliance provisions for the emission rate with add-on controls option. We removed Sec. 63.4162, which was proposed to provide explicit instructions for determining compliance with the emission rate with add-on controls option when the coating operation is operated under several different operating conditions. We found after proposal, however, that this section as proposed added unnecessary complexity to the standards, and that the compliance provisions are adequate without it. Therefore, we removed it from the final standards.

      To provide consistency with other surface coating NESHAP, we added provisions in Sec. 63.4167(b)(3) and (4) to allow sources an alternative to the proposed operating limits for catalytic oxidizers that require monitoring of inlet and outlet temperature before and after the catalyst bed and the temperature difference across the bed. This alternative allows you to monitor only the temperature before the catalyst bed if you develop and follow an onsite inspection and maintenance plan for the catalytic oxidizer. For some sources, this would be a preferable alternative. Another addition we made to provide consistency is a description of continuous monitoring requirements for concentrators in Sec. 63.4167(e) and (f) and in Table 1 to the subpart. As proposed, a source using a concentrator would have had to seek and obtain approval from the permitting authority for the continuous monitoring it wanted to use to comply with the operating limits since we did not include such monitoring provisions in the proposed standards. Because we have included these provisions in the final standards, a source can comply with them and, therefore, avoid having to apply for and obtain specific approval unless it wishes to monitor something different than what is specified in the new provisions. The concentrator monitoring requirements are the same as those in other surface coating NESHAP under development.

      In addition to the revisions described above, we have made clarifying editorial changes throughout the rule to ensure it accurately expresses our intent and to promote consistency with other surface coating NESHAP currently under development. These changes do not affect the stringency of the requirements since they are only clarifications of the proposed provisions.

3. What Are the Final Standards?

   1. What Is the Source Category?

      The large appliances source category includes facilities that apply coatings to large appliance parts or products. The rule applies to facilities that are a major source, are located at a major source, or are part of a major source of HAP emissions. Large appliances include ``white goods'' such as ovens, refrigerators, freezers, dishwashers, laundry equipment, trash compactors, water heaters, comfort furnaces, and electric heat pumps. Large appliances also include most HVAC equipment intended for any application. However, not included in the source category are motor vehicle air-conditioning units, heat transfer coils, and large commercial and industrial chillers. Other coating operations not included in the source category are: the coating of large appliance parts that have a wider use beyond large appliances (such as handles or fasteners), repair or maintenance painting of large appliance parts or products used by a facility, the surface coating of heat transfer coils or large commercial and industrial chillers, research or laboratory facilities and facility maintenance operations, and hobby shops operated for non-commercial purposes.

   2. What Is the Affected Source?

      The affected source includes all of the activities that involve coatings, thinners, and cleaning materials used in large appliance coating operations. These activities include: (1) Surface preparation of the large appliance parts or products; (2) preparation of coatings for application; (3) applying the coatings; (4) flash-off, drying, or curing of the coatings; (5) cleaning of coating equipment; (6) storage of coatings, thinners, and cleaning materials; (7) conveying of these materials; and (8) handling and conveying of waste materials generated by the coating operations.

   3. What Are the Emission Limits?

      The emission limits are different for existing and new sources and have not changed since proposal. For an existing source, you must limit organic HAP emissions to no more than 0.13 kg/liter (1.1 pound (lb)/ gallon (gal)) of coating solids used during each compliance

      [[Page 48259]]

      (monthly) period. For a new or reconstructed source, you must limit emissions to no more than 0.022 kg/liter (0.18 lb/gal) of coating solids. These limits apply to the total of all coatings, thinners, and cleaning materials used in coating operations at the affected source.

      There are three compliance options available for meeting the emission limits. The compliant material option requires that each coating used in the operation meet the limit, and each thinner and cleaning material must contain no organic HAP. Under the emission rate without add-on controls option, you may average all of the coatings, thinners, and cleaning materials together and demonstrate that the overall emission rate is in compliance with the applicable limit. The emission rate with add-on controls option applies to coating operations for which add-on controls are used to meet the limit. Under this option, you must meet certain operating limits for the capture systems and control devices and follow a work practice plan for your material storage, mixing, conveying, and spills.

   4. What Are the Testing and Initial and Continuous Compliance Requirements?

      Existing sources will have to be in compliance no later than July 25, 2005. New and reconstructed sources will have to be in compliance by this same date or upon startup, whichever is later. The initial compliance period begins on the compliance date and ends on the last day of the first full month following this date, except that for new or reconstructed sources required to conduct performance tests the initial compliance period ends on the last day of the first full month following the test. Note that ``month'' means a calendar month or a similar pre-specified period in order to accommodate facility accounting periods. The performance test may be conducted up to 180 days after the compliance date.

      As discussed earlier, the owner or operator must select one of three compliance options for each coating operation, but may change the approach used for any operation at any time. For the compliant material and emission rate without add-on controls option, you will determine the mass of organic HAP in coatings, thinners, and cleaning materials and the volume fraction of coating solids either from manufacturer's formulation data or from test results using the methods in the final rule. Alternative test methods may be used with EPA's approval, and the test method results will prevail over manufacturer's formulation data for compliance purposes. If you use the emission rate with add-on controls option, you need to determine the mass of organic HAP and volume fraction of coating solids as in the other two options and also the capture and control efficiencies of the add-on controls by means of a performance test. As part of this test, you must establish operating limits that can be used on a continuous basis to demonstrate compliance with the emission limit. The final rule specifies the parameters to monitor for the types of emission control systems commonly used in the industry. If the monitoring results indicate no deviations from the operating limits, you would assume the control system is continuing to provide the same control efficiency as demonstrated in the test. If the combination of this efficiency and the total mass of organic HAP in materials used in controlled coating operations continues to be within the applicable emission limit, then continuous compliance is shown for those operations.

   5. What Are the Notification, Recordkeeping, and Reporting Requirements?

      If you are subject to the standards, you must comply with the applicable requirements in the NESHAP General Provisions, subpart A of 40 CFR part 63. The General Provisions notification requirements include: initial notifications, notification of performance test if you are complying using a capture system and control device, Notification of Compliance Status, and additional notifications for affected sources with continuous monitoring systems. The General Provisions also require certain records and periodic reports. Records must be kept for at least 5 years with 2 years of that time being at the facility, and they may be kept in electronic form as long as they are readily available for review.

4. What Are the Environmental, Energy, Cost, and Economic Impacts?

   1. What Are the Air Impacts?

      We estimate that nationwide organic HAP emissions will be reduced by approximately 1.080 megagrams/year (Mg/yr) (1,191 tpy) from existing sources. This represents a 45 percent reduction from the emissions baseline of 2,394 Mg/yr (2,639 tpy).

      For new sources, we are assuming that most will use state-of-the- art coatings (predominantly powder coatings) even in the absence of the standards. These coatings will produce emission levels at or below the requirements of the final standards. Therefore, we are not attributing any emissions reductions from new sources to the final standards.

   2. What Are the Non-Air Health, Environmental, and Energy Impacts?

      As at proposal, we have found that there are no significant expected non-air health, environmental, or energy impacts associated with the final standards. We reached this conclusion by considering the likely control approaches that will be used by existing and new sources. The use of low-HAP coating technologies will not produce any significant impacts on health, energy requirements, or the environment.

   3. What Are the Cost and Economic Impacts?

      The costs for facilities to comply with the final standards result from the switch to reformulated (lower-HAP) coatings, thinners, and cleaning materials. There will also be annual costs for meeting the monitoring, recordkeeping, and reporting (MRR) requirements of the rule.

      For existing sources, the total nationwide annual cost in the 5th year of the standards is estimated to be $1.63 million. This includes approximately $0.48 million of direct costs associated with materials usage and $1.15 million for recordkeeping and reporting.

      For new sources, only the costs of MRR apply. We estimate the annual cost in the 5th year for all new sources to be $341,000.

      Our economic impact analysis showed the economic impacts of the promulgated standards to generally be minimal, with projected price increases and production decreases of less than 0.01 percent. Social costs are estimated at approximately $1.62 million in the 5th year for existing sources, with the burden being shared fairly equally between consumers and producers. No firms or facilities are expected to become at risk of closure due to the final standards. For more information, consult the ``Economic Impact Analysis of the Proposed NESHAP: Surface Coating of Large Appliances'' (Docket No. A-97-41).

5. What Are the Administrative Requirements?

   1. Executive Order 12866, Regulatory Planning and Review

      Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA must determine whether the regulatory action is ``significant'' and therefore subject to the Office of Management and Budget (OMB) review and the requirements of

      [[Page 48260]]

      the Executive Order. The Executive Order defines ``significant regulatory action'' as one that is likely to result in a rule that may:

      (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities;

      (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

      (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligation of recipients thereof; or

      (4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

      Pursuant to the terms of Executive Order 12866, it has been determined that this rule is not a ``significant regulatory action'' because none of the listed criteria apply to this action. Consequently, this action was not submitted to OMB for review under Executive Order 12866.

   2. Executive Order 13045, Protection of Children From Environmental Health Risks and Safety Risks

      Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any rule that: (1) Is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, EPA must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned rule is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

      The EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under section 5-501 of the Executive Order has the potential to influence the rule. These final standards are not subject to Executive Order 13045 because they do not establish an environmental standard based on an assessment of health or safety risks. No children's risk analysis was performed because no alternative technologies exist that would provide greater stringency at a reasonable cost. Furthermore, this rule has been determined not to be ``economically significant'' as defined under Executive Order 12866.

   3. Executive Order 13132, Federalism

      Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ``meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' ``Policies that have federalism implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.''

      This final rule does not have federalism implications. It will not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. Pursuant to the terms of Executive Order 13132, it has been determined that this rule does not have ``federalism implications'' because it does not meet the necessary criteria. Thus, Executive Order 13132 does not apply to this rule.

   4. Executive Order 13175, Consultation and Coordination With Indian Tribal Governments

      Executive Order 13175, entitled ``Consultation and Coordination with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), requires EPA to develop an accountable process to ensure ``meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.'' This final rule does not have tribal implications, as specified in Executive Order 13175. No tribal governments own or operate large appliance surface coating facilities. Thus, Executive Order 13175 does not apply to this rule.

   5. Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use

      This rule is not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) because it is not a significant regulatory action under Executive Order 12866.

   6. Unfunded Mandates Reform Act of 1995

      Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with ``Federal mandates'' that may result in expenditures by State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost-effective, or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective, or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements.

      The EPA has determined that this final rule does not contain a Federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any 1 year. The maximum total annual cost of this rule for any year has been estimated to be slightly less than $2 million. Thus, today's final rule is not subject to the requirements of sections 202 and 205 of the UMRA. In addition, EPA has determined that these standards contain no regulatory requirements that might significantly or uniquely affect small governments because they contain no requirements that apply to such

      [[Page 48261]]

      governments or impose obligations upon them. Therefore, today's final rule is not subject to the requirements of section 203 of the UMRA.

   7. Regulatory Flexibility Act (RFA), as Amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601, et seq.

      The RFA generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions.

      For the purposes of assessing the impacts of today's final rule on small entities, small entity is defined as: (1) A small business ranging from 100-1,000 employees or less than $3.5 million in annual sales; (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.

      In accordance with the RFA and SBREFA, EPA conducted an assessment of these standards on small businesses within the large appliance coating industry. Based on Small Business Administration size definitions and reported sales and employment data, EPA's survey identified 221 facilities that apply surface coatings to large appliances. These facilities, which include major and area sources, are owned by 84 companies. Of these companies, 34 are small businesses. Although small businesses represent about 40 percent of the companies within the source category, they are expected to incur only 10 percent of the total industry compliance costs. Under the final standards, the average annual compliance cost share of sales for small businesses is only 0.20 percent, with 26 of the 34 small businesses not expected to incur any additional costs because they are area sources or are permitted as synthetic minor HAP emission sources. After reviewing the range of costs to be borne by small businesses, EPA has determined the costs are typically small and that this action will not have a significant impact on a substantial number of small entities.

      Although this final rule will not have a significant economic impact on a substantial number of small entities, EPA has nonetheless worked aggressively to minimize the impact of these standards on small entities, consistent with our obligations under the CAA. We solicited input from small entities during the data-gathering phase of the proposed rulemaking. We are including compliance options that give small entities flexibility in choosing the most cost-effective and least burdensome alternative for their operation. For example, a facility could purchase and use low-HAP coatings (i.e., pollution prevention) that meet the final standards instead of using add-on capture and control systems. This method of compliance can be demonstrated with minimum burden by using purchase and usage records. No testing of materials will typically be required as the facility owner will be allowed to show that their coatings meet the emission limits by providing formulation data supplied by the manufacturer.

   8. Paperwork Reduction Act

      The information collection requirements for these final standards will be submitted for approval to OMB under the Paperwork Reduction Act, 44 U.S.C. 3501, et seq. An Information Collection Request (ICR) document has been prepared by EPA (ICR No. 1954.01) and a copy may be obtained from Susan Auby by mail at U.S. EPA, Office of Environmental Information, Collection Strategies Division (2822T), 1200 Pennsylvania Avenue, NW, Washington, DC 20460, by e-mail at auby.susan@epa.gov, or by calling (202) 566-1672. A copy may also be downloaded off the internet at http://www.epa.gov/icr. The information requirements are not effective until OMB approves them.

      The information requirements are based on notification, recordkeeping, and reporting requirements in the NESHAP General Provisions (40 CFR part 63, subpart A), which are mandatory for all operators subject to national emission standards. These recordkeeping and reporting requirements are specifically authorized by section 114 of the CAA (42 U.S.C. 7414). All information submitted to EPA pursuant to the recordkeeping and reporting requirements for which a claim of confidentiality is made is safeguarded according to Agency policies set forth in 40 CFR part 2, subpart B.

      The final standards require maintaining records of all coatings, thinners, and cleaning materials data and calculations used to determine compliance. This information includes the volume used during each monthly compliance period, mass fraction organic HAP, density, and, for coatings only, volume fraction of coating solids.

      If an add-on control device is used, records must be kept of the capture efficiency of the capture system, destruction or removal efficiency of the add-on control device, and the monitored operating parameters. In addition, records must be kept of each calculation of the affected sourcewide emissions for each monthly compliance period and all data, calculations, test results, and other supporting information used to determine this value.

      The MRR burden in the 5th year after the effective date of the promulgated rule is estimated to be 32,000 labor hours at a cost of $1.50 million for new and existing sources.

      Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information.

      An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's rules are listed in 40 CFR part 9 and 48 CFR chapter 15. The OMB control number(s) for the information collection requirements in this rule will be listed in an amendment to 40 CFR part 9 or 48 CFR chapter 15 in a subsequent Federal Register.

1. National Technology Transfer and Advancement Act

   As noted in the proposed rule, section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113 (15 U.S.C. 272 note), directs the EPA to use voluntary consensus standards (VCS) in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. The VCS are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by one or

   [[Page 48262]]

   more VCS bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable VCS.

   This rulemaking involves technical standards. The EPA cites the following standards in this rule: EPA Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 4, 24, 25, 25A, 204, 204A-F, and 311. Consistent with the NTTAA, EPA conducted searches to identify VCS in addition to these EPA methods. No applicable VCS were identified for EPA Methods 1A, 2A, 2D, 2F, 2G, 204, 204A-F, and 311. The search and review results have been documented and are placed in the docket (Docket No. A-97-41) for this rule.

   The four VCS described below were identified as acceptable alternatives to EPA test methods for the purposes of this rule.

   The VCS, ASME PTC 19-10-1981-Part 10, ``Flue and Exhaust Gas Analyses,'' is cited in this rule for its manual method for measuring the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas. This part of ASME PTC 19-10-1981-Part 10 is an acceptable alternative to Method 3B.

   The VCS, ASTM 1475-98, ``Standard Test Method for Density of Liquid Coatings, Inks, and Related Products,'' is cited in this rule for determining the density of coatings and the volatile matter in coatings.

   The two VCS, ASTM D2697-86 (Reapproved 1998), ``Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' and ASTM D6093-97, ``Standard Test Method for Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium Gas Pycnometer,'' are cited in this rule as acceptable alternatives to EPA Method 24 to determine the volume solids content of coatings. Currently, EPA Method 24 does not have a procedure for determining the volume of solids in coatings. These standards augment the procedures in Method 24, which currently states that volume solids content be calculated from the coating manufacturer's formulation.

   Six VCS: ASTM D1475-90, ASTM D2369-95, ASTM D3792-91, ASTM D4017- 96a, ASTM D4457-85 (Reapproved 91), and ASTM D5403-93 are already incorporated by reference (IBR) in EPA Method 24. Five VCS: ASTM D1979- 91, ASTM D3432-89, ASTM D4747-87, ASTM D4827-93, and ASTM PS9-94 are IBR in EPA Method 311.

   In addition to the VCS EPA uses in this rule, the search for emissions measurement procedures identified eleven other VCS. The EPA determined that nine of these eleven standards identified for measuring emissions of the HAP or surrogates subject to emission standards in this rule were impractical alternatives to EPA test methods for the purposes of this rule. Therefore, EPA does not intend to adopt these standards for this purpose. For further information on the determination of the eleven methods, see the docket for this rulemaking (Docket A-97-41).

   Sections 63.4130, 63.4141, 63.4161, 63.4165, and 63.4166, and Table 1 of subpart NNNN list the EPA testing methods included in the final standards. Under Sec. 63.7(f) of Subpart A of the General Provisions, a source may apply to EPA for permission to use alternative test methods in place of any of the EPA testing methods.

   10. Congressional Review Act

       The Congressional Review Act, 5 U.S.C. 801, et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. The EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a major rule as defined by 5 U.S.C. 804(2).

          What This Subpart Covers

          Sec. 63.4080 What is the purpose of this subpart?

          This subpart establishes national emission standards for hazardous air pollutants for large appliance surface coating facilities. This subpart also establishes requirements to demonstrate initial and continuous compliance with the emission limitations.

          Sec. 63.4081 Am I subject to this subpart?

          (

          1. You are subject to this subpart if you own or operate a facility that applies coatings to large appliance parts or products, and is a major source, is located at a major source, or is part of a major source of emissions of hazardous air pollutants (HAP), except as provided in paragraph (d) of this section. A major source of HAP emissions is any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit any single HAP at a rate of 9.07 megagrams (Mg) (10 tons) or more per year or any combination of HAP at a rate of 22.68 Mg (25 tons) or more per year. You are not subject to this subpart if your large appliance surface coating facility is located at, or is part of, an area source of HAP emissions. An area source of HAP emissions is any stationary source or group of stationary sources located within a contiguous area and under common control that is not a major source.

             (b) The large appliance surface coating source category includes any facility engaged in the surface coating of a large appliance part or product.

         Compliance Requirements for the Compliant Material Option

         Sec. 63.4140 By what date must I conduct the initial compliance demonstration?

         You must complete the initial compliance demonstration for the initial compliance period according to the requirements in Sec. 63.4141. The initial compliance period begins on the applicable compliance date specified in Sec. 63.4083 and ends on the last day of the first full month after the compliance date. If the compliance date occurs on any day other than the first day of a month, then the initial compliance period extends through the end of that month plus the next month. The initial compliance demonstration includes the determination according to Sec. 63.4141 and supporting documentation showing that, during the initial compliance period, you used no coating with an organic HAP content that exceeded the applicable emission limit in Sec. 63.4090, and that you used no thinners or cleaning materials that contained organic HAP.

         Sec. 63.4141 How do I demonstrate initial compliance with the emission limitations?

         You may use the compliant material option for any individual coating operation, for any group of coating operations in the affected source, or for all the coating operations in the affected source. You must use either the emission rate without add-on controls option or the emission rate with add-on controls option for any coating operation(s) in the affected source for which you do not use this option. To demonstrate initial compliance using the compliant material option, the coating operation or group of coating operations must use no coating with an organic HAP content that exceeds the applicable emission limit in Sec. 63.4090 and must use no thinner or cleaning material that contains organic HAP, as determined according to this section during the initial compliance period. Any coating operation(s) for which you use the compliant material option is not required to meet the operating limits or work practice standards required in Secs. 63.4092 and 63.4093, respectively. To demonstrate initial compliance with the emission limitations using the compliant material option, you must meet all the requirements of this section for the coating operation(s) using this option. Use the procedures in this section on each coating, thinner, and cleaning material in the condition it is in when it is received from its manufacturer or supplier and prior to any alteration. You do not need to redetermine the HAP content of coatings, thinners, or cleaning materials that have been reclaimed onsite and reused in the coating operation(s) for which you use the compliant material option, provided these materials in their condition as received were demonstrated to comply with the compliant material option. If the mass fraction of organic HAP of a coating equals zero, determined according to paragraph (a) of this section, and you use the compliant material option, you are not required to comply with

         [[Page 48270]]

         paragraphs (b) and (c) of this section for that coating.

         (

      1. Determine the mass fraction of organic HAP for each material used. You must determine the mass fraction of organic HAP for each coating, thinner, and cleaning material used during the compliance period by using one of the options in paragraphs (a)(1) through (5) of this section.

         (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 311 for determining the mass fraction of organic HAP. Use the procedures specified in paragraphs (a)(1)(i) and (ii) of this section when performing a Method 311 test.

         (i) Count each organic HAP that is measured to be present at 0.1 percent by mass or more for Occupational Safety and Health Administration (OSHA)-defined carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds. For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 percent of the material by mass, you do not have to count it. Express the mass fraction of each organic HAP you count as a value truncated to four places after the decimal point (for example, 0.3791).

         (ii) Calculate the total mass fraction of organic HAP in the test material by adding up the individual organic HAP mass fractions and truncating the result to three places after the decimal point (for example, 0.763).

         (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may use Method 24 to determine the mass fraction of nonaqueous volatile matter and use that value as a substitute for mass fraction of organic HAP.

         (3) Alternative method. You may use an alternative test method for determining the mass fraction of organic HAP once the Administrator has approved it. You must follow the procedure in Sec. 63.7(f) to submit an alternative test method for approval.

         (4) Information from the supplier or manufacturer of the material. You may rely on information other than that generated by the test methods specified in paragraphs (a)(1) through (3) of this section, such as manufacturer's formulation data if they represent each organic HAP that is present at 0.1 percent by mass or more for OSHA-defined carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP compounds. For example, if toluene (not an OSHA carcinogen) is 0.5 percent of the material by mass, you do not have to count it. If there is a disagreement between such information and results of a test conducted according to paragraphs (a)(1) through (3) of this section, then the test method results will take precedence.

         (5) Solvent blends. Solvent blends may be listed as single components for some materials in data provided by manufacturers or suppliers. Solvent blends may contain organic HAP which must be counted toward the total organic HAP mass fraction of the materials. When test data and manufacturer's data for solvent blends are not available, you may use the default values for mass fraction of organic HAP in these solvent blends listed in Table 3 or 4 of this subpart. If you use the tables, you must use the values in Table 3 for all solvent blends that match Table 3 entries, and you may only use Table 4 if the solvent blends in the materials you use do not match any of the solvent blends in Table 3, and you only know whether the blend is aliphatic or aromatic. However, if the results of a Method 311 test indicate higher values than those listed on Table 3 or 4 of this subpart, the Method 311 results will take precedence.

         (b) Determine the volume fraction of coating solids for each coating. You must determine the volume fraction of coating solids (liters of coating solids per liter of coating) for each coating used during the compliance period by a test, by information provided by the supplier or the manufacturer of the material, or by calculation as specified in paragraphs (b)(1) through (3) of this section.

         (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' or D6093- 97, ``Standard Test Method for Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium Gas Pycnometer'' (incorporated by reference, see Sec. 63.14) to determine the volume fraction of coating solids for each coating. Divide the nonvolatile volume percent obtained with the methods by 100 to calculate volume fraction of coating solids.

         (2) Information from the supplier or manufacturer of the material. You may obtain the volume fraction of coating solids for each coating from the supplier or manufacturer.

         (3) Calculation of volume fraction of coating solids. If the volume fraction of coating solids cannot be determined using the options in paragraphs (b)(1) and (2) of this section, you must determine it using Equation 1 of this section:

         [GRAPHIC] [TIFF OMITTED] TR23JY02.018

         Where:

         Vs= volume fraction of coating solids, liters coating solids per liter coating. mvolatiles= total volatile matter content of the coating, including HAP, volatile organic compounds (VOC), water, and exempt compounds, determined according to Method 24 in appendix A of 40 CFR part 60, grams volatile matter per liter coating. Davg= average density of volatile matter in the coating, grams volatile matter per liter volatile matter, determined from test results using ASTM Method D1475-98, ``Standard Test Method for Density of Liquid Coatings, Inks, and Related Products'' (incorporated by reference, see Sec. 63.14) information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure materials. If there is disagreement between ASTM Method D1475-98 test results and other information sources, the test results will take precedence.

         (c) Determine the density of each coating. Determine the density of each coating used during the compliance period from test results using ASTM Method D1475-98, ``Standard Test Method for Density of Liquid Coatings, Inks, and Related Products'' (incorporated by reference, see Sec. 63.14), information from the supplier or manufacturer of the material, or reference sources providing density or specific gravity data for pure materials. If there is disagreement between ASTM Method D1475-98 test results and other information sources, the test results will take precedence.

         (d) Determine the organic HAP content of each coating. Determine the organic HAP content, kg organic HAP per liter coating solids, of each coating used during the compliance period, using Equation 2 of this section, except that if the mass fraction of organic HAP equals zero, then the organic HAP content also equals zero and you are not required to use Equation 2 to calculate the organic HAP content:

         [GRAPHIC] [TIFF OMITTED] TR23JY02.019

         Where:

         Hc= organic HAP content of the coating, kg organic HAP per liter coating solids. Dc= density of coating, kg coating per liter coating, determined according to paragraph (c) of this section.

         [[Page 48271]]

         Wc= mass fraction of organic HAP in the coating, kg organic HAP per kg coating, determined according to paragraph (a) of this section. Vs= volume fraction of coating solids, liters coating solids per liter coating, determined according to paragraph (b) of this section.

         (e) The organic HAP content for each coating used during the initial compliance period must be less than or equal to the applicable emission limit in Sec. 63.4090; and each thinner and cleaning material used during the initial compliance period must contain no organic HAP, determined according to paragraph (a) of this section. You must keep all records required by Secs. 63.4130 and 63.4131. As part of the Notification of Compliance Status required in Sec. 63.4110, you must identify the coating operation(s) for which you used the compliant material option and submit a statement that the coating operation(s) was (were) in compliance with the emission limitations during the initial compliance period because you used no coatings for which the organic HAP content exceeds the applicable emission limit in Sec. 63.4090, and you used no thinners or cleaning materials that contain organic HAP, determined according to paragraph (a) of this section.

         Sec. 63.4142 How do I demonstrate continuous compliance with the emission limitations?

         (

      1. For each compliance period, to demonstrate continuous compliance, you must use no coating for which the organic HAP content, determined according to Sec. 63.4141(d), exceeds the applicable emission limit in Sec. 63.4090, and use no thinner or cleaning material that contains organic HAP, determined according to Sec. 63.4141(a). Each month following the initial compliance period described in Sec. 63.4140 is a compliance period.

         (b) If you choose to comply with the emission limitations by using the compliant material option, the use of any coating, thinner, or cleaning material that does not meet the criteria specified in paragraph (a) of this section is a deviation from the emission limitations that must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(d).

         (c) As part of each semiannual compliance report required by Sec. 63.4120, you must submit a statement that you were in compliance with the emission limitations during the reporting period because you used no thinners or cleaning materials that contained organic HAP, and you used no coatings for which the organic HAP content exceeded the applicable emission limit in Sec. 63.4090.

         (d) You must maintain records as specified in Secs. 63.4130 and 63.4131.

         Compliance Requirements for the Emission Rate Without Add-On Controls Option

         Sec. 63.4150 By what date must I conduct the initial compliance demonstration?

         You must complete the initial compliance demonstration for the initial compliance period according to the requirements of Sec. 63.4151. The initial compliance period begins on the applicable compliance date specified in Sec. 63.4083 and ends on the last day of the first full month after the compliance date. If the compliance date occurs on any day other than the first day of a month, then the initial compliance period extends through the end of that month plus the next month. The initial compliance demonstration includes the calculations according to Sec. 63.4151 and supporting documentation showing that the organic HAP emission rate for the initial compliance period was equal to or less than the applicable emission limit in Sec. 63.4090.

         Sec. 63.4151 How do I demonstrate initial compliance with the emission limitations?

         You may use the emission rate without add-on controls option for any individual coating operation, for any group of coating operations in the affected source, or for all of the coating operations in the affected source. You must use either the compliant material option or the emission rate with add-on controls option for any coating operation(s) in the affected source for which you do not use this option. To demonstrate initial compliance using the emission rate without add-on controls option, the coating operation(s) must meet the applicable emission limit in Sec. 63.4090 but not the operating limits or work practice standards in Secs. 63.4092 and 63.4093, respectively, during the initial compliance period. You must meet all of the requirements of this section to demonstrate initial compliance with the applicable emission limit in Sec. 63.4090 for the coating operation(s). When calculating the organic HAP emission rate according to this section, do not include any coatings, thinners, or cleaning materials used on coating operations for which you use the compliant material option or the emission rate with add-on controls option. You do not need to redetermine the mass of organic HAP in coatings, thinners, or cleaning materials that have been reclaimed onsite and reused in the coating operation(s) for which you use the emission rate without add-on controls option.

Instead, you must maintain a log detailing the operation and maintenance of the emission capture system, add-on control device, and continuous parameter monitors during the period between the compliance date and the performance test. You must begin complying with the operating limits for your affected source on the date you complete the performance tests specified in paragraph (b)(1) of this section. This requirement does not apply to solvent recovery systems for which you conduct liquid- liquid material balances according to Sec. 63.4161(h).

         Sec. 63.4161 How do I demonstrate initial compliance?

         You may use the emission rate with add-on controls option for any coating operation, for any group of coating operations in the affected source, or for all of the coating operations in the affected source. You may include both controlled and uncontrolled coating operations in a group for which you use this option. You must use either the compliant material option or the emission rate without add-on controls option for any coating operation(s) in the affected source for which you do not use this option.

         (f) Calculate the organic HAP emission reduction for each controlled coating operation. Determine the mass of organic HAP emissions reduced for each controlled coating operation during the compliance period. The emissions reduction determination quantifies the total organic HAP emissions that pass through the emission capture system and are destroyed or removed by the add-on control device. Use the procedures in paragraph (g) of this section to calculate the mass of organic HAP emissions reduction for each controlled coating operation using an emission capture system and add-on control device other than a solvent recovery system for which you conduct liquid- liquid material balances. For each controlled coating operation using a solvent recovery system for which you conduct a liquid-liquid material balance, use the procedures in paragraph (h) of this section to calculate the organic HAP emissions reduction.

         (g) Calculate the organic HAP emissions reduction for controlled coating operations not using liquid-liquid material balance. For each controlled coating operation using an emission capture system and add- on control device other than a solvent recovery system for which you conduct liquid-liquid material balances, calculate organic HAP emissions reduction, using Equation 1 of this section, by applying the emission capture system efficiency and add-on control device efficiency to the mass of organic HAP contained in the coatings, thinners, and cleaning materials that are used in the coating operation served by the emission capture system and add-on control device during the compliance period. For any period of time a deviation specified in Sec. 63.4163(c) or (d) occurs in the controlled coating operation, including a deviation during a period of startup, shutdown, or malfunction, you must assume zero efficiency for the emission capture system and add-on control device. For the purposes of completing the compliance calculations, you must treat the materials used during a deviation on a controlled coating operation as if they were used on an uncontrolled coating operation for the time period of the deviation. You must not include those materials in the calculations of organic HAP emissions reduction in Equation 1 of this section.

To demonstrate continuous compliance with the applicable emission limit in Sec. 63.4090, the organic HAP emission rate for each compliance period determined according to the procedures in Sec. 63.4161 must be equal to or less than the applicable emission limit in Sec. 63.4090. Each month following the initial compliance period described in Sec. 63.4160 is a compliance period.

         (b) If the organic HAP emission rate for any compliance period exceeded the applicable emission limit in Sec. 63.4090, this is a deviation from the emission limitation for that compliance period and must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g).

         (c) You must demonstrate continuous compliance with each operating limit required by Sec. 63.4092 that applies to you as specified in Table 1 to this subpart.

         (1) If an operating parameter is out of the allowed range specified in Table 1 to this subpart, this is a deviation from the operating limit that must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g).

         (2) If an operating parameter deviates from the operating limit specified in Table 1 to this subpart, then you must assume that the emission capture system and add-on control device were achieving zero efficiency during the time period of the deviation. For the purposes of completing the compliance calculations specified in Sec. 63.4161, you must treat the materials used during a deviation on a controlled coating operation as if they were used on an uncontrolled coating operation for the time period of the deviation. You must not include those materials in the calculation of organic HAP emissions reductions in Equation 1 of Sec. 63.4161.

         (d) You must meet the requirements for bypass lines in Sec. 63.4168(b). If any bypass line is opened and emissions are diverted to the atmosphere when the coating operation is running, this is a deviation that must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g). For the purposes of completing the compliance calculations specified in Sec. 63.4161, you must treat the materials used during a deviation on a controlled coating operation as if they were used on an uncontrolled coating operation for the time period of the deviation. You must not include those materials in the calculation of organic HAP emissions reductions in Equation 1 of Sec. 63.4161.

         (e) You must demonstrate continuous compliance with the work practice standards in Sec. 63.4093. If you did not develop a work practice plan, or you did not implement the plan, or you did not keep the records required by Sec. 63.4130(k)(9), this is a deviation from the work practice standards that must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g).

         (f) As part of each semiannual compliance report required in Sec. 63.4120, you must submit a statement that you were in compliance with the emission limitations during the reporting period because the organic HAP emission rate for each compliance period was less than or equal to the applicable emission limit in Sec. 63.4090, and you achieved the operating limits required by Sec. 63.4092 and the work practice standards required by Sec. 63.4093 during each compliance period.

         (g) During periods of startup, shutdown, and malfunction of the emission capture system, add-on control device, or coating operation that may affect emission capture or control device efficiency, you must operate in accordance with the SSMP required by Sec. 63.4100(d).

         (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that occur during a period of startup, shutdown, or malfunction of the emission capture system, add-on control device, or coating operation that may affect emission capture or control device efficiency are not violations if you demonstrate to the Administrator's satisfaction that you were operating in accordance with the SSMP. The Administrator will determine whether deviations that occur during a period of startup, shutdown, or malfunction are violations according to the provisions in Sec. 63.6(e).

         (i) [Reserved]

         (j) You must maintain records as specified in Secs. 63.4130 and 63.4131.

         Sec. 63.4164 What are the general requirements for performance tests?

         (

      1. You must conduct each performance test required by Sec. 63.4160 according to the requirements in Sec. 63.7(e)(1) and under the conditions in this section unless you obtain a waiver of the performance test according to the provisions in Sec. 63.7(h).

         (1) Representative coating operation operating conditions. You must conduct the performance test under

         [[Page 48277]]

         representative operating conditions for the coating operation. Operations during periods of startup, shutdown, or malfunction and periods of nonoperation do not constitute representative conditions. You must record the process information that is necessary to document operating conditions during the test and explain why the conditions represent normal operation.

         (2) Representative emission capture system and add-on control device operating conditions. You must conduct the performance test when the emission capture system and add-on control device are operating at a representative flow rate, and the add-on control device is operating at a representative inlet concentration. You must record information that is necessary to document emission capture system and add-on control device operating conditions during the test and explain why the conditions represent normal operation.

         (b) You must conduct each performance test of an emission capture system according to the requirements in Sec. 63.4165 and of an add-on control device according to the requirements in Sec. 63.4166.

         (c) The performance test to determine add-on control device organic HAP destruction or removal efficiency must consist of three runs as specified in Sec. 63.7(e)(3) and each run must last at least 1 hour.

         Sec. 63.4165 How do I determine the emission capture system efficiency?

         You must use the procedures and test methods in this section to determine capture efficiency as part of the performance test required by Sec. 63.4160.

         (

      1. You may assume the capture system efficiency is 100 percent if both of the conditions in paragraphs (a)(1) and (2) of this section are met:

         (1) The capture system meets the criteria in Method 204 of appendix M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the enclosure to an add-on control device.

         (2) All coatings, thinners, and cleaning materials used in the coating operation are applied within the capture system; coating solvent flash-off and coating, curing, and drying occurs within the capture system and the removal or evaporation of cleaning materials from the surfaces they are applied to occurs within the capture system. For example, this criterion is not met if parts enter the open shop environment when being moved between a spray booth and a curing oven.

         (b) If the capture system does not meet both of the criteria in paragraphs (a)(1) and (2) of this section, then you must use one of the three protocols described in paragraphs (c), (d), and (e) of this section to measure capture efficiency. The capture efficiency measurements use TVH capture efficiency as a surrogate for organic HAP capture efficiency. For the protocols in paragraphs (c) and (d) of this section, the capture efficiency measurement must consist of three test runs. Each test run must be at least 3 hours duration or the length of a production run, whichever is longer, up to 8 hours. For the purposes of this test, a production run means the time required for a single part to go from the beginning to the end of production which includes surface preparation activities and drying or curing time.

         (c) Liquid-to-uncaptured-gas protocol using a temporary total enclosure or building enclosure. The liquid-to-uncaptured-gas protocol compares the mass of liquid TVH in materials used in the coating operation, to the mass of TVH emissions not captured by the emission capture system. Use a temporary total enclosure or a building enclosure and the procedures in paragraphs (c)(1) through (6) of this section to measure emission capture system efficiency using the liquid-to- uncaptured-gas protocol.

         (1) Either use a building enclosure or construct an enclosure around the coating operation where coatings, thinners, and cleaning materials are applied, and all areas where emissions from these applied coatings and materials subsequently occur, such as flash-off, curing, and drying areas. The areas of the coating operation where capture devices collect emissions for routing to an add-on control device, such as the entrance and exit areas of an oven or spray booth, must also be inside the enclosure. The enclosure must meet the applicable definition of a temporary total enclosure or building enclosure in Method 204 of appendix M to 40 CFR part 51.

         (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to determine the mass fraction of TVH liquid input from each coating, thinner, and cleaning material used in the coating operation during each capture efficiency test run. To make the determination, substitute TVH for each occurrence of the term VOC in the methods.

         (3) Use Equation 1 of this section to calculate the total mass of TVH liquid input from all the coatings, thinners, and cleaning materials used in the coating operation during each capture efficiency test run.

         [GRAPHIC] [TIFF OMITTED] TR23JY02.013

         Where:

         TVHused= total mass of TVH liquid input from all coatings, thinners, and cleaning materials used in the coating operation during the capture efficiency test run, kg. TVHi= mass fraction of TVH in coating, thinner, or cleaning material, i, that is used in the coating operation during the capture efficiency test run, kg TVH per kg material. Voli= total volume of coating, thinner, or cleaning material, i, used in the coating operation during the capture efficiency test run, liters. Di= density of coating, thinner, or cleaning material, i, kg material per liter material. n = number of different coatings, thinners, and cleaning materials used in the coating operation during the capture efficiency test run.

         (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure the total mass, kg, of TVH emissions that are not captured by the emission capture system; they are measured as they exit the temporary total enclosure or building enclosure during each capture efficiency test run. To make the measurement substitute TVH for each occurrence of the term VOC in the methods.

         (i) Use Method 204D if the enclosure is a temporary total enclosure.

         (ii) Use Method 204E if the enclosure is a building enclosure. During the capture efficiency measurement, all organic compound emitting operations inside the building enclosure, other than the coating operation for which capture efficiency is being determined must be shut down, but all fans and blowers must be operating normally.

         [[Page 48278]]

         (5) For each capture efficiency test run, determine the percent capture efficiency of the emission capture system, using Equation 2 of this section:

         [GRAPHIC] [TIFF OMITTED] TR23JY02.014

         Where:

         CE = capture efficiency of the emission capture system vented to the add-on control device, percent. TVHused= total mass of TVH liquid input used in the coating operation during the capture efficiency test run, kg. TVHuncaptured= total mass of TVH that is not captured by the emission capture system and that exits from the temporary total enclosure or building enclosure during the capture efficiency test run, kg.

         (6) Determine the capture efficiency of the emission capture system as the average of the capture efficiencies measured in the three test runs.

         (d) Gas-to-gas protocol using a temporary total enclosure or a building enclosure. The gas-to-gas protocol compares the mass of TVH emissions captured by the emission capture system to the mass of TVH emissions not captured. Use a temporary total enclosure or a building enclosure and the procedures in paragraphs (d)(1) through (5) of this section to measure emission capture system efficiency using the gas-to- gas protocol.

         (1) Either use a building enclosure or construct an enclosure around the coating operation where coatings, thinners, and cleaning materials are applied and all areas where emissions from these applied coatings and materials subsequently occur such as flash-off, curing, and drying areas. The areas of the coating operation where capture devices collect emissions generated by the coating operation for routing to an add-on control device, such as the entrance and exit areas of an oven or a spray booth, must also be inside the enclosure. The enclosure must meet the applicable definition of a temporary total enclosure or building enclosure in Method 204 of appendix M to 40 CFR part 51.

         (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to measure the total mass, kg, of TVH emissions captured by the emission capture system during each capture efficiency test run as measured at the inlet to the add-on control device. To make the measurement, substitute TVH for each occurrence of the term VOC in the methods.

         (i) The sampling points for the Method 204B or 204C measurement must be upstream from the add-on control device and must represent total emissions routed from the capture system and entering the add-on control device.

         (ii) If multiple emission streams from the capture system enter the add-on control device without a single common duct, then the emissions entering the add-on control device must be simultaneously measured in each duct, and the total emissions entering the add-on control device must be determined.

         (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to measure the total mass, kg, of TVH emissions that are not captured by the emission capture system; they are measured as they exit the temporary total enclosure or building enclosure during each capture efficiency test run. To make the measurement, substitute TVH for each occurrence of the term VOC in the methods.

         (i) Use Method 204D if the enclosure is a temporary total enclosure.

         (ii) Use Method 204E if the enclosure is a building enclosure. During the capture efficiency measurement, all organic compound emitting operations inside the building enclosure other than the coating operation for which capture efficiency is being determined must be shut down, but all fans and blowers must be operating normally.

         (4) For each capture efficiency test run, determine the percent capture efficiency of the emission capture system, using Equation 3 of this section:

         [GRAPHIC] [TIFF OMITTED] TR23JY02.015

         Where:

         CE = capture efficiency of the emission capture system vented to the add-on control device, percent. TVHcaptured= total mass of TVH captured by the emission capture system as measured at the inlet to the add-on control device during the emission capture efficiency test run, kg. TVHuncaptured= total mass of TVH that is not captured by the emission capture system and that exits from the temporary total enclosure or building enclosure during the capture efficiency test run, kg.

         (5) Determine the capture efficiency of the emission capture system as the average of the capture efficiencies measured in the three test runs.

         (e) Alternative capture efficiency protocol. As an alternative to the procedures specified in paragraphs (c) and (d) of this section, you may determine capture efficiency using any other capture efficiency protocol and test methods that satisfy the criteria of either the DQO or LCL approach as described in appendix A to subpart KK of this part.

         Sec. 63.4166 How do I determine the add-on control device emission destruction or removal efficiency?

         (

      1. For all types of add-on control devices, use the test methods as specified in paragraphs (a)(1) through (5) of this section.

         (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as appropriate, to select sampling sites and velocity traverse points.

         (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 60, as appropriate, to measure gas volumetric flow rate.

         (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as appropriate, for gas analysis to determine dry molecular weight. You may also use as an alternative to Method 3B, the manual method for measuring the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas in ANSI/ASME, PTC 19.10-1981, ``Flue

         [[Page 48279]]

         and Exhaust Gas Analyses'' (incorporated by reference, see Sec. 63.14).

         (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack gas moisture.

         (5) Methods for determining gas volumetric flow rate, dry molecular weight, and stack gas moisture must be performed, as applicable, during each test run.

         (b) Measure total gaseous organic mass emissions as carbon at the inlet and outlet of the add-on control device simultaneously, using either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in paragraphs (b)(1) through (3) of this section. You must use the same method for both the inlet and outlet measurements.

         (1) Use Method 25 if the add-on control device is an oxidizer and you expect the total gaseous organic concentration as carbon to be more than 50 parts per million (ppm) at the control device outlet.

         (2) Use Method 25A if the add-on control device is an oxidizer and you expect the total gaseous organic concentration as carbon to be 50 ppm or less at the control device outlet.

         (3) Use Method 25A if the add-on control device is not an oxidizer.

         (c) If two or more add-on control devices are used for the same emission stream, then you must measure emissions at the outlet of each device. For example, if one add-on control device is a concentrator with an outlet for the high-volume, dilute stream that has been treated by the concentrator, and a second add-on control device is an oxidizer with an outlet for the low-volume, concentrated stream that is treated with the oxidizer, you must measure emissions at the outlet of the oxidizer and the high-volume dilute stream outlet of the concentrator.

         (d) For each test run, determine the total gaseous organic emissions mass flow rates for the inlet and the outlet of the add-on control device, using Equation 1 of this section. If there is more than one inlet or outlet to the add-on control device, you must calculate the total gaseous organic mass flow rate using Equation 1 of this section for each inlet and each outlet and then total all of the inlet emissions and total all of the outlet emissions.

         [GRAPHIC] [TIFF OMITTED] TR23JY02.016

         Where:

         Mf= total gaseous organic emissions mass flow rate, kg/per hour (h). Cc= concentration of organic compounds as carbon in the vent gas, as determined by Method 25 or Method 25A, parts per million by volume (ppmv), dry basis. Qsd= volumetric flow rate of gases entering or exiting the add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, dry standard cubic meters/hour (dscm/h). 0.0416 = conversion factor for molar volume, kg-moles per cubic meter (mol/m \3\) (@ 293 Kelvin (K) and 760 millimeters of mercury (mm Hg)).

         (e) For each test run, determine the add-on control device organic emissions destruction or removal efficiency, using Equation 2 of this section.

         [GRAPHIC] [TIFF OMITTED] TR23JY02.017

         Where:

         DRE = add-on control device organic emissions destruction or removal efficiency, percent. Mfi= total gaseous organic emissions mass flow rate at the inlet(s) to the add-on control device, using Equation 1 of this section, kg/h. Mfo= total gaseous organic emissions mass flow rate at the outlet(s) of the add-on control device, using Equation 1 of this section, kg/h.

         (f) Determine the emission destruction or removal efficiency of the add-on control device as the average of the efficiencies determined in the three test runs and calculated in Equation 2 of this section.

Use the data collected during the performance test to calculate and record the average temperature just before the catalyst bed during the performance test. This is the minimum operating limit for your catalytic oxidizer.

         (4) You must develop and implement an inspection and maintenance plan for your catalytic oxidizer(s) for which you elect to monitor according to paragraph (b)(3) of this section. The plan must address, at a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) of this section.

         (iii) Annual internal and monthly external visual inspection of the catalyst bed to check for channeling, abrasion, and settling. If problems are found, you must take corrective action consistent with the manufacturer's recommendations and conduct a new performance test to determine

         [[Page 48280]]

         destruction efficiency according to Sec. 63.4166.

         (c) Carbon adsorbers. If your add-on control device is a carbon absorber, establish the operating limits according to paragraphs (c)(1) and (2) of this section.

         (1) During the performance test, you must monitor and record the condenser outlet (product side) gas temperature at least once every 15 minutes during each of the three test runs.

         (2) Use the data collected during the performance test to calculate and record the average condenser outlet (product side) gas temperature maintained during the performance test. This average condenser outlet gas temperature is the maximum operating limit for your condenser.

         (e) Concentrators. If your add-on control device includes a concentrator, you must establish operating limits for the concentrator according to paragraphs (e)(1) through (4) of this section.

         (1) During the performance test, you must monitor and record the desorption concentrate stream gas temperature at least once every 15 minutes during each of the three runs of the performance test.

         (2) Use the data collected during the performance test to calculate and record the average temperature. This is the minimum operating limit for the desorption concentrate gas stream temperature.

         (3) During the performance test, you must monitor and record the pressure drop of the dilute stream across the concentrator at least once every 15 minutes during each of the three runs of the performance test.

         (2) Calculate and record the average gas volumetric flow rate or duct static pressure for the three test runs for each capture device. This average gas volumetric flow rate or duct static pressure is the minimum operating limit for that specific capture device.

         Sec. 63.4168 What are the requirements for continuous parameter monitoring system installation, operation, and maintenance?

         (

      1. General. You must install, operate, and maintain each CPMS specified in paragraphs (c), (e), (f), and (g) of this section according to paragraphs (a)(1) through (6) of this section. You must install, operate, and maintain each CPMS specified in paragraphs (b) and (d) of this section according to paragraphs (a)(3) through (5) of this section.

         (1) The CPMS must complete a minimum of one cycle of operation for each successive 15-minute period. You must have a minimum of four equally spaced successive cycles of CPMS operation in 1 hour.

         (2) You must determine the average of all recorded readings for each successive 3-hour period of the emission capture system and add-on control device operation except as specified in paragraph (a)(6) of this section.

         (3) You must record the results of each inspection, calibration, and validation check of the CPMS.

         (4) You must maintain the CPMS at all times and have available necessary parts for routine repairs of the monitoring equipment.

         (5) You must operate the CPMS and collect emission capture system and add-on control device parameter data at all times that a controlled coating operation is operating except during monitoring malfunctions, associated repairs, and required quality assurance or control activities (including, if applicable, calibration checks and required zero and span adjustments).

         (6) You must not use emission capture system or add-on control device parameter data recorded during monitoring malfunctions, associated repairs, out-of-control periods, or required quality assurance or control activities when calculating data averages. You must use all the data collected during all other periods in calculating the data averages for determining compliance with the emission capture system and add-on control device operating limits.

         (7) A monitoring malfunction is any sudden, infrequent, not reasonably preventable failure of the CPMS to provide valid data. Monitoring failures that are caused in part by poor maintenance or careless operation are not malfunctions. Except for periods of required quality assurance or control activities, any period during which the CPMS fails to operate and record data continuously as required by paragraph (a)(1) of this section, or generates data that cannot be included in calculating averages as specified in paragraph (a)(6) of this section, is a deviation from the monitoring requirements.

         (b) Capture system bypass line. You must comply with the requirements of paragraphs (a)(3) through (5) and (b)(1) and (2) of this section for each emission capture system that contains bypass lines that could divert emissions away from the add-on control device to the atmosphere.

         (1) You must monitor or secure the valve or closure mechanism controlling the bypass line in a nondiverting position in such a way that the valve or closure mechanism cannot be opened without creating a record that the valve was opened. The method used to monitor or secure the valve or closure mechanism must meet one of the requirements specified in paragraphs (b)(1)(i) through (iv) of this section.

         (i) Flow control position indicator. Install, calibrate, maintain, and operate according to the manufacturer's specifications a flow control position indicator that takes a reading at least once every 15 minutes and provides a record indicating whether the emissions are directed to the add-on control device or diverted from the add-on control device.
