National Emission Standards for Hazardous Air Pollutants: Aerospace Manufacturing and Rework Facilities
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule; amendments.
SUMMARY: This action proposes to amend the national emission standards for hazardous air pollutants (NESHAP) for Aerospace Manufacturing and Rework Facilities to include a separate emission standard for exterior primers used for large commercial aircraft components (parts or assemblies) or fully assembled large commercial aircraft at existing facilities that produce fully assembled large commercial aircraft. We are proposing these amendments based on review of data that support significant technical concerns of an aircraft manufacturer's ability to achieve the current 350 grams per liter (g/L) (2.9 pounds per gallon (lb/gal)) hazardous air pollutant (HAP) and volatile organic compound (VOC) content limit requirements when using exterior primers.

Why Are We Taking This Action?
On September 1, 1995, we promulgated the NESHAP for Aerospace Manufacturing and Rework Facilities (60 FR 45948). The NESHAP contains standards to control organic HAP and VOC emissions from primer application operations. These standards require the use of a primer with an organic HAP and VOC content level of 350 g/L (2.9 lb/gal) or less (40 CFR 63.745(c)(1),(2)) where no add-on control system is used, or the use of a control system to reduce the organic HAP and VOC emissions to the atmosphere by 81 percent or greater (Sec. 63.745(d)). We set these standards at the maximum achievable control technology (MACT) floor for new and existing sources.
In the preamble to the proposed NESHAP (59 FR 29241), we explained the basis of the MACT floor for primer application operations. We established the MACT floor for existing facilities based on the weighted average VOC content that represented the average of the top 12 percent of facilities. Because of the limited available data on the corresponding organic HAP content, we proposed a HAP content limit at the same level as the VOC content limit. Also, in applying these standards within the source category, we did not identify any technical reason to distinguish between the different types of market segments (commercial or military), or the work type (original equipment manufacture or rework). Therefore, we applied these standards to all market segments within the source category.
In public comments received on the proposed rule, aircraft manufacturers raised concerns about the inclusion of exterior primers for large commercial aircraft in the data set for the MACT floor on primer operations. The industry expressed concerns about whether a suitable exterior primer would be available by the September 1, 1998 NESHAP compliance deadline for existing sources. However, at that time, industry did not provide adequate supporting data to justify separate treatment of exterior primers for large commercial aircraft.
Recently, an aircraft manufacturer raised these same concerns and submitted additional data indicating that it has not been able to find a satisfactory exterior primer for use in manufacturing and assembling large commercial aircraft that will meet the current HAP and VOC content limits in the NESHAP and their own performance needs. This aircraft manufacturer has stated that several factors exist that create a distinction between facilities that produce fully assembled large commercial aircraft and facilities that manufacture other types of aerospace components and vehicles. One of the primary differences is the annual utilization rates for large commercial aircraft versus other aircraft. Large commercial aircraft often remain in constant use with multiple take-offs and landings daily and much higher annual flight hours than other aircraft. The total flight time, flight frequency, and flight altitudes for large commercial aircraft are often much higher than for other types of aircraft, such as defense aircraft and general aviation aircraft. These higher utilization rates associated with large commercial aircraft create distinct stresses for the paint systems used. In addition, the largest of the commercial aircraft are often designed for overseas travel (transcontinental routes) which creates a greater exposure to salt, a strong corrosive agent. Finally, this aircraft manufacturer has stated that differing paint requirements, such as replicability of color and gloss, and differing maintenance requirements due to its large number of customers (200 plus), are also factors that can contribute to the acceptability of a paint system. This aircraft manufacturer expressed significant technical concern about its ability to find an exterior primer that would provide adequate protection to large commercial aircraft without pitting or peeling and that would meet the VOC and HAP content standards for primers. This aircraft manufacturer has stated that available low-VOC exterior primers have very different physical and chemical properties, such as the rheology and cross-link density of the coating, from the primers that were in use when the MACT floor was established in 1995. Primers that were in use at that time contained 1,1,1
[[Page 3644]]
trichloroethane (TCA) but TCA has since been phased out due to its adverse effect on the stratospheric ozone layer. New TCA-free, high solids/low-VOC primers represent a distinct technology from the previous TCA primer technology. The manufacturer has stated that this has resulted in changes to the performance characteristics of the primer, particularly the adhesion, flexibility, and impact resistance, which have resulted in a greater chance of the coatings peeling and pitting. This aircraft manufacturer provided summary test data on the 50 exterior primers tested since the Aerospace NESHAP was promulgated.
The compliance date for the NESHAP was September 1, 1998. We have granted compliance extensions based on this issue; however, these extensions expired September 1, 1999.
Today, we are proposing to amend the current emission limits contained in 40 CFR 63.745(c)(1) and (2) for primer operations with no add-on control systems by proposing a separate emission limit of 650 g/ L (5.4 lb/gal) or less of organic HAP and VOC for exterior primers as applied to large commercial aircraft components (parts or assemblies) or fully assembled large commercial aircraft at existing affected sources that produce fully assembled large commercial aircraft; and an emission limit of 350 g/L (2.9 lb/gal) or less of organic HAP and VOC for exterior primers as applied to large commercial aircraft components (parts or assemblies) or fully assembled large commercial aircraft at new affected sources that produce fully assembled large commercial aircraft. Our bases for these amendments are data recently submitted to us by a manufacturer of large commercial aircraft and a reevaluation of the original data used to establish the MACT floor for primer application operations. Also based on the fact that TCA-based primer is no longer available, as previously discussed, we reevaluated the original data used to establish the MACT floor for primer application operations of 350 g/L (2.9 lb/gal) or less of organic HAP and VOC.
In order to determine if a separate limit should be established for exterior primers used on large commercial aircraft at existing facilities that produce fully assembled large commercial aircraft, we considered whether these facilities are distinct from other segments of the industry. Because large commercial aircraft often have much higher annual utilization rates and greater exposure to corrosive environments, creating the need for higher performance coating systems, and the manufacturer of such aircraft has many different customer specifications it must satisfy, we determined that a separate limit should be established for these facilities. We then re-evaluated the original data only for facilities that manufactured fully assembled large commercial aircraft. In our re-evaluation of the data, we identified four facilities which manufactured fully assembled large commercial aircraft. To account for the fact that TCA-based primer is no longer available, we removed all TCA-based primer data. The data from these four facilities on the annual usage of primers used in the primer operations for large commercial aircraft had a VOC content that ranged from 650 g/L (5.3 lb/gal) to 670 g/L (5.6 lb/gal). A more detailed discussion of this analysis can be found in the Docket (No. A- 92-20) within the document titled, ``MACT Floor for Aerospace Commercial Aircraft Original Equipment Operations--Interior and Exterior Primers.''
The Clean Air Act requires that emission standards for HAP established under section 112(d)(2) be based on ``* * * the maximum degree of reduction in emissions of the hazardous air pollutants subject to this section * * * that the Administrator, taking into consideration the cost of achieving such emission reduction, and any non-air quality health and environmental impacts and energy requirements, determines is achievable for new or existing sources in the category or subcategory to which such emission standards applies * * *.'' This basis is commonly referred to as MACT.
Section 112(d)(3) further clarifies the minimum acceptable stringency for the MACT level of emission reduction. For new sources, MACT shall be no ``* * * less stringent than the emission control that is achieved in practice by the best controlled similar source, as determined by the Administrator.'' For existing sources, MACT ``* * * shall not be less stringent, and may be more stringent than--
(A) the average emission limitation achieved by the best performing 12 percent of the existing sources * * * in the category or subcategory for categories and subcategories with 30 or more sources, or
(B) the average emission limitation achieved by the best performing five sources * * * in the category or subcategory for categories or subcategories with fewer than 30 sources.''
In prior rulemaking where fewer than five sources exist, we have based the MACT floor for existing sources on the average emission limitation achieved by all the sources. Use of the arithmetic average would result in a VOC content of 655 g/L. This method for calculating the MACT floor yields a number that does not correspond to an actual VOC content of primer used at these facilities. Therefore, we determined the MACT floor for these four facilities based on the median VOC content for primer operations at these facilities. The MACT floor for primer operations at these facilities is 650 g/L (5.4 lb/gal) or less of organic HAP and VOC. This represents the existing source MACT floor for all primer operations at facilities that manufacture fully assembled large commercial aircraft.
We then considered exterior versus interior primers. The data recently submitted to us by the aircraft manufacturer relate only to technical problems concerning the use of ``exterior'' primers at existing facilities that manufacture fully assembled large commercial aircraft. We do not have any data indicating that similar problems exist with the use of interior primers at these facilities. We believe that the 350 g/L (2.9 lb/gal) level has already been demonstrated to be an achievable level of control for interior primers used at facilities that manufacture fully assembled large commercial aircraft. Therefore, we propose to go beyond the MACT floor level of control (650 g/L (2.9 lb/gal) or less of organic HAP and VOC to 350 g/L (2.9 lb/gal) or less of organic HAP and VOC for interior primer operations used at existing and new facilities that manufacture fully assembled large commercial aircraft.
We are not proposing to establish MACT at a level beyond the MACT floor for exterior primers used on large commercial aircraft at facilities that produce fully assembled large commercial aircraft. This is because we believe that meeting a standard more stringent than a 650 g/L level is not technically achievable for all existing commercial production facilities that manufacture and assemble large commercial aircraft at this time. However, the manufacturer in question has stated that it will continue to test and evaluate exterior primers, used to manufacture and assemble large commercial aircraft, with the goal of achieving the current content limit of 350 g/L. Should this manufacturer find an exterior primer that meets its specifications and is lower than the proposed content limit of 650 g/L prior to promulgation of these proposed amendments, we intend to promulgate an emission limit for exterior primers used on large commercial aircraft at facilities that manufacture fully
[[Page 3645]]
assembled large commercial aircraft that would be at this lower level.
For new sources, section 112(d)(3) states that MACT ``* * * shall not be less stringent than the emission control that is achieved in practice by the best controlled similar source, as determined by the Administrator.''
Based on our reevaluation of these original data, the new source MACT floor for primer operations used on large commercial aircraft at facilities that produce fully assembled large commercial aircraft is 650 g/L (5.4 lb/gal) or less of organic HAP and VOC. This represents the ``best controlled similar source'' from these four facilities. Since the original data were collected, new high-solids chemistry, without TCA, has been employed to achieve the 350 g/L levels. Some existing sources may not be able to use this new technology, combined with other changes to low-HAP and low-VOC topcoats and new application techniques, because of design constraints in their overall operation. The use of this technology may only be feasible for facilities with maximum flexibility in physical plant, climate control, contaminant control (keeping the surface clean prior to primer application), etc. However, for a new source that manufactures fully assembled large commercial aircraft, the operation as a whole could be designed to accommodate the new high-solids technology. Indeed, at least one large commercial aircraft facility is currently using this technology (Boeing Long Beach facility, formerly the McDonnell Douglas facility). This is new information that is not in the original data set used to determine the MACT floor.
Based on the recent data provided, EPA concludes that although technological problems exist at the 350 g/L level for most of the existing facilities, manufacturers can design new facilities with this new technology in mind. Thus, we believe that it is appropriate to set MACT above the floor for new facilities. As a result, we propose to set the limit for exterior primer used on large commercial aircraft at new facilities that produce fully assembled large commercial aircraft at 350 g/L (2.9 lb/gal) or less of organic HAP and VOC.
Although we are not addressing other sectors of the industry, such as the military, in today's proposal, we reviewed the data from the remainder of the responses to section 114 questionnaires for these sectors of the aerospace manufacturing and rework industry that perform primer operations. Our preliminary analysis indicates that the MACT floor for these sectors of the industry would also be in the range of 650 g/L, assuming that we removed the TCA-based data from the data set. However, even if the floor for these sectors were to change, we would see no reason not to adopt the current 350 g/L limit as an above-the- floor requirement. We have received no information indicating that this limit is not achievable for these sectors of the industry. In addition, on September 1, 1998, we issued amendments to the Aerospace NESHAP (63 FR 46533) that set new standards for the control of organic HAP and VOC emissions from primer and topcoat application operations for general aviation rework facilities. We believe that those standards resolved any similar problems for the general aviation rework facilities. Therefore, the proposed organic HAP and VOC emission limit of 650 g/L (5.4 lb/gal) or less for exterior primers applies only to large commercial aircraft components (parts or assemblies) or fully assembled large commercial aircraft at existing affected sources that produce fully assembled large commercial aircraft.
In deciding how to define ``large commercial aircraft,'' we evaluated several different criteria. A review of current Federal Aviation Agency (FAA) regulations revealed two definitions of large aircraft in the Code of Federal Regulations, Title 14 (-) Aeronautics and Space. Under title 14, part 1, general definitions are provided which are applicable for the majority of FAA regulations, sub-chapters A through K. Part 1.1 of title 14 defines large aircraft as ``an aircraft of more than 12,500 pounds, maximum certified take-off weight.'' Under 14 CFR 268.1, which is a regulation applicable to air carriers known as air taxi operators and commuter air carrier operations, large aircraft is defined as ``any aircraft designed to have a maximum passenger capacity of more than 60 seats or a maximum payload capacity of more than 18,000 pounds.'' These definitions suggest the use of maximum certified take-off weight, maximum payload capacity, or maximum passenger capacity as possible criteria to define large aircraft. However, factors cited in the data submitted by the aircraft manufacturer indicated that total flight time, flight frequency and flight altitudes were distinguishing criteria which create more demanding performance characteristics for exterior primers used to manufacture and assemble large commercial aircraft. This suggests that one or all of these criteria could serve as another possible alternative for defining large commercial aircraft.
Based on our review of the data, we believe that the weight of the aircraft is the best defining factor. Greater weight frequently is related to aircraft that are designed to have greater flight time, flight frequency and flight altitude. After reviewing the FAA definitions of large aircraft, we believe that maximum take-off weight would be an appropriate criterion to define large commercial aircraft. The maximum take-off weight is well known and documented within the industry. However, based on the data received, the current definition within FAA regulations (a maximum take-off weight of 12,500 lbs) does not characterize the size of the aircraft where we believe the problems exist for exterior primers.
With respect to the second part of this definition, ``commercial,'' this manufacturer has not indicated that this is a problem for the large military aircraft it manufactures. Therefore, we are defining the term commercial to exclude large aircraft manufactured for military use.
We are proposing to define a large commercial aircraft as an aircraft of more than 110,000 pounds, maximum certified take-off weight manufactured for non-military use. We are requesting comments on this definition along with the use of the other criteria discussed for defining large commercial aircraft.

What Provisions of the Aerospace NESHAP Would These Proposed Amendments Affect?
We are proposing to amend section 63.745(c)(1) and (2) of the NESHAP by adding a separate HAP and VOC content limit of 650 g/L for exterior primers applied to large commercial aircraft components (parts or assemblies) or fully assembled large commercial aircraft at existing affected sources that produce fully assembled large commercial aircraft.
-
Whom Would These Proposed Amendments Affect?
These proposed amendments would affect you if you are the owner or operator of an existing or new exterior primer application operation at a facility that, either in part or in whole, manufactures and assembles large commercial aircraft and is a major source as defined in 40 CFR 63.2.

What Are the Administrative Requirements for This Proposal?
-
Executive Order 12866, Regulator Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA must
[[Page 3646]]
determine whether the regulatory action is ``significant'' and, therefore, subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The Executive Order defines ``significant regulatory action'' as one that is likely to result in standards 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 entitlement, grants, user fees, or loan programs or the rights and obligations 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.
It has been determined that this proposed rule is not a ``significant regulatory action'' under the terms of Executive Order 12866 and is, therefore, not subject to OMB review.
-
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 is determined to be ``economically significant'' as defined under Executive Order 12866, and 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, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation 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 regulation. This proposal is not subject to Executive Order 13045 because it is based on technology performance and not on health or safety risks.
-
Paperwork Reduction Act
These proposed amendments would not impose any new information collection requirements would result in no change to the currently approved collection. The OMB has approved the information collection requirements contained in the Aerospace Manufacturing and Rework Facilities NESHAP under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB Control Number 2060-0314.
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 regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.
-
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 purposes of assessing the impacts of today's proposed amendments on small entities, small entity is defined as: (1) A small business that has less than 1,500 employees; (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.
After considering the economic impacts of today's proposed amendments on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. These proposed amendments will not impose any requirements on small entities. They affect only manufacturers of large commercial aircraft. There are no small-entity manufacturers of large commercial aircraft.

Unfunded Mandates Reform Act
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 to 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.
Today's proposed amendments contain no Federal mandates (under the regulatory provisions of title II of the UMRA) for State, local, or tribal governments or the private sector. These proposed amendments would amend certain existing emission limits in a de-regulatory manner and would not impose any new enforceable duty on any State, local or tribal governments or the private sector. Thus, today's proposed amendments are not subject to the requirements of sections 202 and 205 of the UMRA. The EPA has determined that this rule contains no regulatory requirements that might significantly or uniquely affect small governments. Thus, today's proposed amendments are not subject to the requirements of section 203 of the UMRA.

Executive Order 13084, Consultation and Coordination With Indian Tribal Governments
Under Executive Order 13084, EPA may not issue a regulation that is not required by statute, that significantly or uniquely affects the communities of Indian tribal governments, and that imposes substantial direct compliance
[[Page 3647]]
costs on those communities, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by the tribal governments, or EPA consults with those governments. If EPA complies by consulting, Executive Order 13084 requires EPA to provide to OMB, in a separately identified section of the preamble to the rule, a description of the extent of EPA's prior consultation with representatives of affected tribal governments, a summary of the nature of their concerns, and a statement supporting the need to issue the regulation. In addition, Executive Order 13084 requires EPA to develop an effective process permitting elected officials and other representatives of Indian tribal governments ``to provide meaningful and timely input in the development of regulatory policies on matters that significantly or uniquely affect their communities.''
Today's proposed amendments do not significantly or uniquely affect the communities of Indian tribal governments. Accordingly, the requirements of section 3(b) of Executive Order 13084 do not apply to these proposed amendments.
-
National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law No. 104-113, section 12(d) (15 U.S.C. 272 note), directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., material specifications, test methods, sampling and analytical procedures, and business practices) that are developed or adopted by one or more voluntary consensus standard bodies. The NTTAA directs EPA to provide Congress, through OMB, with explanations when EPA decides not to use available and applicable voluntary consensus standards.
These proposed action amendments do not involve technical standards. Therefore, EPA is not considering the use of any voluntary consensus standards.
-
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.''
Under Section 6 of Executive Order 13132, EPA may not issue a regulation that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by State and local governments, or EPA consults with State and local officials early in the process of developing the proposed regulation. The EPA also may not issue a regulation that has federalism implications and that preempts State law, unless the Agency consults with State and local officials early in the process of developing the proposed regulation.
These proposed amendments do not have federalism implications. They 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. These proposed amendments would amend portions of an existing rule, the Aerospace NESHAP, in a de-regulatory manner. They would not impose any obligations on State or local governments. Thus, the requirements of section 6 of the Executive Order do not apply to this rule.
