RIN 2120-AA64

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2019-19-06, which applies to certain Airbus SAS Model A330-202, -243, -
243F, -302, -323, and -343 airplanes. AD 2019-19-06 requires an
inspection to determine the part number and serial number of the slat
geared rotary actuators (SGRAs), and replacement of each affected SGRA
with a serviceable part. Since the FAA issued AD 2019-19-06, it was
determined that the requirements of AD 2019-19-06 may not ensure the
permanent removal from service of affected SGRAs. This proposed AD
would continue to require replacement of each affected SGRA with a
serviceable part, and would expand the applicability to include all
airplanes on which the affected part may be installed. This proposed AD
would also prohibit installation of an affected part, as specified in a
European Union Aviation Safety Agency (EASA) AD, which is proposed for
incorporation by reference. The FAA is proposing this AD to address the
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by May 24,
2021.

Discussion

    The FAA issued AD 2019-19-06, Amendment 39-19742 (84 FR 51960,
October 1, 2019) (AD 2019-19-06), which applies to certain Airbus SAS
Model A330-202, -243, -243F, -302, -323, and -343 airplanes. AD 2019-
19-06 requires an inspection to determine the part number and serial
number of the SGRAs, and replacement of each affected SGRA with a
serviceable part. The FAA issued AD 2019-19-06 to address cracking of
an SGRA, which, in combination with an independent failure on the
second SGRA of the same slat surface, could lead to an uncontrolled
movement of the affected slat surface in flight, or detachment of the
slat surface, and could possibly result in damage to the stabilizers
and reduced controllability of the airplane.

Actions Since AD 2019-19-06 Was Issued

    Since the FAA issued AD 2019-19-06, it was confirmed that the
affected parts were still installed on the airplanes specified in that
AD. It was also determined that the requirements of AD 2019-19-06 may
not ensure the permanent removal from service of affected SGRAs.
Therefore, affected parts that were removed from airplanes could later
be installed on other airplanes. EASA and the FAA have determined that
a new AD is necessary to prohibit the (re)installation of affected
parts.
    The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0245, dated November 9, 2020
(EASA AD 2020-0245) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all Airbus A330-201, A330-202, A330-203, A330-223, A330-223F, A330-
243, A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-
323, A330-341, A330-342, A330-343, A330-743L, A330-841, and A330-941
airplanes. EASA AD 2020-0245 supersedes EASA AD 2019-0093 (which
corresponds to FAA AD 2019-19-06). Model A330-743L airplanes are not
certificated by the FAA and are not included on the U.S. type
certificate data sheet; this AD therefore does not include those
airplanes in the applicability.
    This proposed AD was prompted by a report that cracks have been
found within the ring gears of the SGRAs due to a change in the
manufacturing process and inadequate post-production non-destructive
testing for potential cracking, and a determination that the
requirements of AD 2019-19-06 may not ensure the permanent removal from
service of affected SGRAs. The FAA is proposing this AD to address
cracking of an SGRA, which, in combination with an independent failure
on the second SGRA of the same slat surface, could lead to an
uncontrolled movement of the affected slat surface in flight, or
detachment of the slat surface, and could possibly result in damage to
the stabilizers and reduced controllability of the airplane. See the
MCAI for additional background information.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the
requirements of AD 2019-19-06, this proposed AD would retain certain
requirements of AD 2019-19-06. Those requirements are referenced in
EASA AD 2020-0245, which, in turn, is referenced in paragraph (g) of
this proposed AD.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0245 describes procedures for replacing each affected
SGRA, and specifies a prohibition against installation of an affected
part.
    This material is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
referenced above. The FAA is proposing this AD because the FAA
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified
in EASA AD 2020-0245 described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA initially worked with Airbus and EASA to develop a
process to use certain EASA ADs as the primary source of information
for compliance with requirements for corresponding FAA ADs. The FAA has
since coordinated with other manufacturers and civil aviation
authorities (CAAs) to use this process. As a result, EASA AD 2020-0245
will be incorporated by reference in the FAA final rule. This proposed
AD would, therefore, require compliance with EASA AD 2020-0245 in its
entirety, through that incorporation, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular
section in the EASA AD does not mean that operators need comply only
with that section. For example, where the AD requirement refers to
``all required actions and compliance times,'' compliance with this AD
requirement is not limited to the section titled ``Required Action(s)
and Compliance

Time(s)'' in the EASA AD. Service information specified in EASA AD
2020-0245 that is required for compliance with EASA AD 2020-0245 will
be available on the internet at https://www.regulations.gov by
searching for and locating Docket No. FAA-2021-0261 after the FAA final
rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 123 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                Cost on U.S.
             Action                     Labor cost          Parts cost     Cost per  product       operators
----------------------------------------------------------------------------------------------------------------
Retained action from AD 2019-19- 17 work-hours x $85 per            * $0  $1,445............  $177,735.
 06.                              hour = $1,445.
New proposed actions...........  Up to 15 work-hours x              * $0  Up to $1,275......  Up to $156,825.
                                  $85 per hour = Up to
                                  $1,275.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost estimates for the parts specified in this
  proposed AD.

    According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators. The FAA does not control warranty
coverage for affected operators. As a result, the FAA has included all
known costs in the cost estimate

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect 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.
    For the reasons discussed above, I certify this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

DOCUMENT IDENTIFICATION

Agency:	Maricopa County Air Quality Department (MCAQD or County)

SIP Approved Version:	There is no previous SIP-approved MCAQD RACT SIP for the 2008 8-hour ozone standard, nor for the 1997 8-hour ozone standard.

Subject of this TSD:	Analysis of Reasonably Available Control Technology For The 2008 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) State Implementation Plan (RACT SIP)

	Appendix 1A: Negative Declarations

	Adopted - May 24, 2017
	Submitted - June 22, 2017

Completeness Finding:   Complete by operation of law - December 22, 2017

 BACKGROUND

Volatile organic compounds (VOC) and nitrogen oxides (NOx) in the presence of sunlight can lead to the formation of ground-level ozone or "smog" which can result in significant impacts to human health and the environment. Section 182 of the Clean Air Act (CAA) requires areas that are classified as Moderate or above for ozone nonattainment to implement reasonably available control technology (RACT) for specific types of sources.

The Phoenix-Mesa, Arizona ozone nonattainment area is classified as a Moderate ozone nonattainment area for the 2008 8-hour national ambient air quality standard ("NAAQS") for ozone (May 4, 2016, 81 FR 26697 and 40 CFR 81.303). The Phoenix-Mesa, Arizona ozone nonattainment area includes portions of Maricopa and Pinal Counties, and expressly excludes portions of Indian Country. MCAQD regulates those portions of the Phoenix-Mesa, Arizona ozone nonattainment area that lie within Maricopa County.

Under CAA § 182(b)(2) and (f), the MCAQD must, at a minimum, adopt RACT-level controls for sources covered by a Control Techniques Guidelines (CTG) document and for any major stationary source of VOC or NOx. The EPA defines RACT as the "lowest emissions limitation that a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility."  44 FR 53761 (September 17, 1979). A RACT analysis should, therefore, take into account the technological and economic feasibility of controls, and may differ from source to source and location to location.

 SUBMITTAL SUMMARY

The MCAQD adopted its RACT SIP certification for the 2008 ozone standard on May 24, 2017, and the Arizona Department of Environmental Quality (ADEQ) submitted it to the EPA on June 22, 2017. The MCAQD performed its RACT SIP analysis based on an ozone non-attainment classification of "Moderate." This classification defines a major source as those facilities that emit or have the potential to emit at least 100 tons per year (tpy) of VOC or NOx. 42 USC §§ 7511a(b), (f), 7602(j).

The MCAQD's submittal includes the following documents:
 "Analysis of Reasonably Available Control Technology For The 2008 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) State Implementation Plan (RACT SIP)," dated December 5, 2016 [hereinafter "2016 RACT SIP"].

 Maricopa County Board of Supervisors' Certified Agenda Item and Action Taken on May 24, 2017.

The MCAQD's analysis includes the following elements:
       Evaluation of CTG Source Categories
       Evaluation of Non-CTG Source Categories
       Major sources identified
       Negative declarations

Further discussion is provided below.

 EPA EVALUATION

The EPA evaluated the following elements of the MCAQD submission:
 Efforts to identify non-CTG major sources within the MCAQD portion of the nonattainment area
 The bases for concluding local rules implement RACT
 Negative declarations

The MCAQD submittal contained newly-adopted rules, certifications that existing rules implement RACT, and negative declarations. This TSD addresses the categories for which the County either certified that existing rules implement RACT or provided a negative declaration.  The newly-adopted rules are addressed in separate TSDs and Federal Register notices as described in part IV below.

The following documents were also used to support our review:

 "Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard  -  Phase 2" (70 FR 71612; November 29, 2005).

The following summarizes MCAQD actions to address RACT requirements and the EPA's evaluation of those actions.

As an overview, the Department identified major sources for VOCs and NOx in Maricopa County.  They also identified RACT rules implemented for the Serious Area (1-hour) Ozone SIP dated December 2000.  The 2016 RACT SIP includes an analysis of CTG source categories and the accompanying Maricopa rules.  The Department determined which CTG source categories had no emitting facilities in Maricopa County and submitted a negative declaration for several CTG source categories.  Additionally, the Department determined which CTG source categories only had emitting facilities below the CTG threshold.  A negative declaration was also submitted for these CTG source categories.  The 2016 RACT SIP also includes an analysis of the non-CTG major source categories and the accompanying Maricopa rules.

 Efforts to identify non-CTG major sources within the MCAQD portion of the nonattainment area

      RACT is required for source categories covered by an EPA Control Techniques Guidelines document ("CTG sources") and all sources that are not covered by a CTG document but are "major sources" (i.e., for MCAQD, non-CTG sources that emit or have the potential to emit at least 100 tpy of VOCs or NOx).

      MCAQD action

      Non-CTG major sources - MCAQD's 2016 RACT SIP identifies the major sources of VOCs and NOx by facility name, and Appendix B of the 2016 RACT SIP provides a RACT analysis of non-CTG source categories.  MCAQD also provided supplementary information including a table listing the facility names, type of pollutants, source type, and applicable SIP rules.

      The table below reflects the information in MCAQD's 2016 RACT SIP and the "Supplemental Table 1  -  Major Sources of NOx and VOC in Maricopa County," showing all the major sources identified by the MCAQD with at least 100 tpy potential to emit VOC or NOx in the Maricopa County nonattainment area, and the applicable rules for these sources.  The bolded rule numbers represent rules which cover a primary emission source.

*This table contains all major sources in Maricopa County, within the nonattainment area.  However, the asterisked sources are the non-CTG major sources.

      EPA evaluation
      For major non-CTG stationary sources of VOCs or NOx, we reviewed Maricopa's list of Title V Permit sources and EPA's 2011 and 2014 National Emissions Inventory to determine if there were any major sources potentially missing from MCAQD's 2016 RACT SIP analysis and supplemental tables. We identified sources listed in the Title V Permit source list that were not included in the County's list of major sources and supplemental tables. However, we were able to determine that these sources were not, in fact, major sources for VOC or NOx.

 The MCAQD Title V Permit source list includes Butterfield Station Facility (Permit # V98003), Glendale Mun Sanitary Landfill (Permit # V97015), Northwest Regional Landfill (Permit # V97016), Skunk Creek Landfill (Permit # V97019), Southwest Regional Landfill (Permit # V97023), and SR 85 Landfill Public Works Dept (Permit # V03002). These landfills are required to have a Title V permit, but are not major sources for VOC or NOx.   Therefore, RACT is not required for these sources.
 The MCAQD Title V Permit source list shows CMC Steel Fabricators Inc (Permit # V07001) as a major source.  Upon review of the permit, this is a major source for carbon monoxide (CO), but not for VOCs or NOx. Therefore, RACT is not required for this source (CAA § 182(b)(2)).
 The current MCAQD Title V Permit source list shows Intel Corp-Ocotillo Campus (Permit # V15002) as a major source.  Upon review of the most recent permit, this has only recently become a major source for VOC and NOx.  However, the initial permit issued limited the facility-wide emissions to below the major source threshold, as did the revision of the operating permit just prior to the finalizing date of the 2016 RACT SIP adoption in December 2016. Accordingly, the facility was not a major source at the time the 2016 RACT SIP was submitted. Additionally, EPA's 2014 NEI shows emissions of 40.6 tpy VOC and 38.6 tpy NOx.  Because the facility was not a major source at the time the 2016 RACT SIP was submitted, we do not consider Intel Corp-Ocotillo Campus a major source for the purpose of the present RACT SIP. However, future RACT SIP submittals may be required to demonstrate RACT for this source.
 The MCAQD Title V Permit source list shows Marlam Industries (Permit # V97022) as a major source.  Upon review of the permit, this is a synthetic minor source of VOC (that is, the source has taken an enforceable permit limit to emit less than the major source threshold). Therefore, this is not a major source for RACT.

      There are four other sources listed in the Title V Permit Sources list which are also addressed in a supplemental table provided by MCAQD, but not identified in the 2016 RACT SIP:

 Goodrich Corporation (Permit # V97007) and Honeywell International (Permit # V97008) facilities are Title V Permitted sources operating as aerospace manufacturing sources.  However, Goodrich Corporation is a Title V Permitted sources due to HAP emissions and Honeywell International is a major source for NOx. Goodrich Corporation is not major for VOC or NOx, but is a CTG source for the Aerospace manufacturing CTG.
 Maax Spas Industries Corp (Permit # V97005) and Mesa Fully Formed LLC (Permit # V97027) are Title V Permitted sources operating as industrial adhesive sources, which is a CTG RACT category.

      Based on MCAQD's major sources list in the RACT analysis and supplemental tables, we conclude that MCAQD properly identified all major non-CTG sources requiring RACT.  These sources are listed in Table 1 of this TSD. The four sources identified from the Title V Permit Sources list that are not identified in the 2016 RACT SIP are CTG sources.

 The bases for concluding local rules implement RACT

      In 2000, the MCAQD analyzed CTG source categories to ensure that County rules covering these sources implemented RACT for the purpose of the 1-hour ozone NAAQS.  For the purpose of the 2016 RACT SIP, MCAQD analyzed these rules again to ensure that they meet current RACT. Based on this analysis, MCAQD determined that 6 VOC RACT rules and 3 NOx RACT rules needed to be revised to meet current RACT. Accordingly, MCAQD decided to revise these 6 VOC RACT rules and 3 NOx RACT rules.

      MCAQD's Appendices A and B contain analysis of the RACT source categories and the associated rules.  Appendix A describes the 15 VOC CTG categories for which the County found it had applicable sources. Appendix B describes the NOx RACT sources.  In Appendix A, the MCAQD identified the following two existing SIP-approved rules as meeting RACT:

 Rule 331 Solvent Cleaning (amended 4/21/04): MCAQD concluded that Rule 331 meets current RACT based on comparisons to the two solvent cleaning CTGs, "Control of Volatile Organic Emissions from Solvent Metal Cleaning" (EPA-450/2-77-022) and "Control Techniques Guidelines: Industrial Cleaning Solvents" (EPA-453/R-06-001).
       Complete  -  the EPA concurs that Rule 331 as approved into the SIP on December 21, 2004, meets RACT.

 Rule 337 Graphic Arts (amended 8/17/11): MCAQD concluded Rule 337 meets RACT as determined by a comparison with the relevant CTGs: "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume VIII: Graphic Arts- Rotogravure and Flexography" (EPA-430/2-78-033) and "Offset Lithographic Printing and Letterpress Printing" (EPA-453/R06-002).   The most recent revision of the rule incorporated changes such as expanding the standards section of the rule to include additional categories and requirements.
       Complete  -  the EPA approved Rule 337 into the SIP on August 27, 2019 (84 FR 44701), finding that the rule met current RACT. Accordingly, the EPA concurs that Rule 337 meets RACT.

      The County also identified in Appendices A and B the following nine rules, which it recently updated and submitted along with its 2016 RACT SIP to satisfy the RACT requirement for the listed CTG source categories:

 Rule 336 Surface Coating Operations (amended 9/2/16): MCAQD revised this rule to meet additional CTGs.  The CTGs met are: "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume II: Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles, and Light-Duty Trucks" (EPA-450/2-77-008), "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume III: Surface Coating of Metal Furniture" (EPA-450/2-77-032),  "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume V: Surface Coating of Large Appliances (EPA-450/2-77-034), "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume VI: Surface Coating of Miscellaneous Metal Parts and Products" (EPA-450/2-78-15), "Control Techniques Guidelines for Metal Furniture Coatings" (EPA-453/R-07-005), "Control Techniques Guidelines for Large Appliance Coatings" (EPA-453/R07-004), "Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts Coatings" (EPA-453/R-08-003), and "Control Techniques Guidelines For Paper, Film, and Foil Coatings" (EPA-453/R-07-003).  MCAQD concluded Rule 336 meets RACT as determined by comparisons with the CTGs.
       Addressed in separate proposal  -  the EPA believes that Rule 336 needs to be amended.  The EPA proposed a conditional approval of Rule 336 and the County's RACT demonstration for associated CTGs on January 28, 2020 (85 FR 4928), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval of the rule. If the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs. Because we have already proposed action on this rule and the associated CTG source categories, we are not proposing action on this rule in this proposal.

 Rule 342 Coating Wood Furniture and Fixtures (amended 9/2/16): MCAQD concluded Rule 342 meets RACT as determined by a comparison with the EPA's CTG, "Control of Volatile Organic Compound Emissions from Wood Furniture Manufacturing Operations" (EPA-453/R-96-007).  The latest amendment of the rule includes an updated table of VOC limits and the addition of a VOC leak detection and repair section.
       Complete  -  the EPA approved Rule 342 into the SIP on August 27, 2019 (84 FR 44701), finding that the rule met current RACT. Accordingly, the EPA concurs that Rule 342 meets RACT.

 Rule 350 Storage and Transfer of Organic Liquids (Non-Gasoline) at an Organic Liquid Distribution Facility (amended 9/2/16): MCAQD concluded Rule 350 meets RACT as determined by comparison with the EPA's two CTGs, "Control of Volatile Organic Emissions from Storage of Petroleum Liquids in Fixed Roof Tanks" (EPA-450/2-77-036) and "Control of Volatile Organic Emissions from Petroleum Liquid Storage in External Floating Roof Tanks" (EPA-450/2-78-047).
       Addressed in separate action  - The EPA conditionally approved Rule 350 and the County's RACT demonstration for associated CTGs on February 26, 2020 (85 FR 10986), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. As noted in our final action, if the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs. Accordingly, we are not acting on this rule, or the associated CTG source categories in this action.

 Rule 351 Storage and Loading of Gasoline at Bulk Gasoline Plants and Bulk Gasoline Terminals (amended 9/2/16): MCAQD concluded Rule 351 meets RACT as determined by comparison with EPA's two CTGs, "Control of Hydrocarbons from Tank Truck Gasoline Loading Terminals" (EPA-450/2-77-026) and "Control of Volatile Organic Emissions from Bulk Gasoline Plans" (EPA-450/2-77-035).
       Addressed in separate action  - The EPA conditionally approved Rule 351 and the County's RACT demonstration for associated CTGs on February 26, 2020 (85 FR 10986), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. As noted in our final action, if the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs. Accordingly, we are not acting on this rule, or the associated CTG source categories in this action.

 Rule 352 Gasoline Cargo Tank Testing and Use (amended 9/2/16): MCAQD concluded Rule 352 meets RACT as determined by comparison to EPA's CTG, "Control of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems" (EPA-450-2-78-051).
       Addressed in separate action  - The EPA conditionally approved Rule 352 and the County's RACT demonstration for associated CTGs on February 26, 2020 (85 FR 10986), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. As noted in our final action, if the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs. Accordingly, we are not acting on this rule, or the associated CTG source categories in this action.

 Rule 353 Storage and Loading of Gasoline at Gasoline Dispensing Facilities (amended 9/2/16): MCAQD concluded Rule 353 meets RACT as determined by comparison to EPA's CTG, "Design Criteria for Stage I Vapor Control Systems- Gasoline Service Stations" (EPA-450/R-75-102).
       Addressed in separate action  - The EPA conditionally approved Rule 353 and the County's RACT demonstration for associated CTGs on February 26, 2020 (85 FR 10986), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. As noted in our final action, if the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and the associated CTGs. Accordingly, we are not acting on this rule, or the associated CTG source categories in this action.

 Rule 322 Power Plant Operations (amended 9/2/16): MCAQD concluded Rule 322 meets RACT as determined by comparing NOx limits to Imperial County Rule 400.1 as well as documentation provided by stakeholders.  The rule was revised to capture more equipment and to lower NOx limits.
       Addressed in separate action  -  The EPA disapproved Rule 322 on July 20, 2020 (85 FR 43692), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. We are not acting on this rule in this action. However, because the EPA has disapproved Rule 322, there does not exist a SIP-approved rule establishing RACT level controls for sources covered by this rule. As described above, there are major sources of NOx that are covered by this rule. Accordingly, we must propose to disapprove the Maricopa County 2016 RACT SIP with respect to major sources of NOx.

 Rule 323 Fuel Burning Equipment From Industrial/Commercial/Institutional (ICI) Sources (amended 9/2/16): MCAQD concluded Rule 323 meets RACT as determined by comparing NOx limits to Imperial County Rule 400.1.  The rule was revised to lower NOx limits.
       Addressed in separate action  - The EPA conditionally approved Rule 323 on July 20, 2020 (85 FR 43692), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. If the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and its RACT obligation for major sources of NOx covered by this rule. Accordingly, we are not acting on this rule in this action.

 Rule 324 Stationary Internal Combustion (IC) Engines (amended 9/2/16): MCAQD concluded Rule 324 meets RACT as determined by comparing emissions limits in NSPS Subparts III, JJJJ, and various California SIP rules from Placer County, Sacramento, and Ventura County.
       Addressed in separate action  - The EPA conditionally approved Rule 324 on July 20, 2020 (85 FR 43692), finding that the rule mostly implemented RACT, but identifying a limited number of deficiencies. The County has committed to correct these deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. If the County corrects the identified deficiencies and the EPA approves the updated rule, the County will have met its RACT obligation for this rule, and its RACT obligation for major sources of NOx covered by this rule. Accordingly, we are not acting on this rule in this action.

      In appendix C, the County also concluded that the following rule satisfies current RACT and does not require amending for RACT. We agree with the County's assessment that no changes to this rule are needed to demonstrate RACT for the 2008 ozone standard.

 Rule 358 Polystyrene Foam Operations (amended 8/25/97): This rule is listed in the CTG RACT Spreadsheet in Appendix C. It covers operations from at least one major VOC source in the County. Additionally, MCAQD correctly submitted a negative declaration for the CTG category of Polymer Manufacturing because the two CTGs, "Control of Volatile Organic Compound Emissions from Manufacture of High Density Polyethylene, Polypropylene, and Polystyrene Resins" (EPA-450/3-83-008 (November 1983)) and "Control of Volatile Organic Compound Leaks from Synthetic Organic Chemical and Polymer Manufacturing Equipment" (EPA-450/3-83-006 (March 1984)), do not cover the same operations that are performed at the major source and are covered by Rule 358.  Since there is no CTG for the emission sources in this category, MCAQD has determined that the SIP-approved rule does meet RACT based on a RACT analysis prepared by the Eastern Research Group (ERG) on the major source, New Wincup Holding, Inc. The EPA agrees that Rule 358 as approved into the SIP on May 26, 2005 meets RACT.

 Negative declarations where there are no facilities subject to a CTG

      In lieu of adopting RACT rules, districts may adopt negative declarations for CTG source categories if there are no sources in the district covered by the CTG. Negative declarations are not required for ACTs.

      MCAQD Action
      The County reviewed its permit files and emission inventory and used standard industrial classification (SIC) codes and standard classification codes (SCC) to identify businesses subject to the various EPA CTGs. MCAQD used permitting information to also determine if facility emissions exceeded CTG thresholds.  Lastly, MCAQD staff (from Compliance and Permitting divisions) were asked about potential sources subject to CTGs. MCAQD adopted negative declarations for the CTG source categories shown in the tables in Appendix A of the 2016 RACT SIP Analysis and Appendix 1A of the submittal.  MCAQD adopted these negative declarations on May 24, 2017, and they were submitted for SIP approval on June 22, 2017. Supplemental information to MCAQD's 2016 RACT SIP states that additional research indicates there are sources subject to the aerospace and industrial adhesive CTGs.  The supplemental information also claims Rule 336 covers the CTG categories: Large Appliance Coating, Metal Furniture Coating, Cans, Coils, Paper, and Fabric Coating, and Paper, Film, and Foil Coating.

   *The EPA is proposing to disapprove the negative declaration for the Aerospace and Industrial Adhesives as described below in the conclusion section.

      EPA Evaluation
      The County certified that it examined its permit files, emissions inventory and other documentation and determined that there are either no sources or only sources below the CTG threshold in the CTG source categories listed in their negative declaration and included in Table 2. The County adopted the negative declarations on May 24, 2017, after reasonable notice and public comment. Subsequent to submission, the County conducted additional research and determined that they did in fact have applicable sources in two source categories, aerospace and industrial adhesives, making these categories inappropriate for negative declarations.

      The EPA searched the National Emissions Inventory for Maricopa County and verified that there did not appear to be facilities in the MCAQD subject to the remaining CTG categories. Accordingly, we conclude that with the exception of the aerospace and industrial adhesives categories, the submitted negative declarations are consistent with the relevant policy and guidance. However, the negative declarations for the aerospace and industrial adhesives CTGs are not approvable.

 EPA ACTIONS ON OTHER MARICOPA COUNTY RACT SIP ELEMENTS

Due to its size and complexity, the EPA is acting on the MCAQD 2016 RACT SIP submittal in five separate actions. These actions are as follows:

 On August 27, 2019 (84 FR 44701), the EPA approved Rule 342 into the SIP, finding that the rule met current RACT. This rulemaking also approved Rule 337, which had been submitted earlier and was not part of the 2016 RACT SIP submittal. Although we approved Rules 337 and 342, and found that they established RACT level controls, we did not in that action approve the 2016 RACT SIP for the associated CTG source categories. We now propose to do so in this action.
 On January 28, 2020 (85 FR 4928), the EPA proposed conditional approval of Rule 336 into the SIP, as well as conditional approval of the associated CTG source categories for the County's 2016 RACT SIP: "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume II: Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles, and Light-Duty Trucks" (EPA-450/2-77-008), "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume III: Surface Coating of Metal Furniture" (EPA-450/2-77-032),  "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume V: Surface Coating of Large Appliances (EPA-450/2-77-034), "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume VI: Surface Coating of Miscellaneous Metal Parts and Products" (EPA-450/2-78-15), "Control Techniques Guidelines for Metal Furniture Coatings" (EPA-453/R-07-005), "Control Techniques Guidelines for Large Appliance Coatings" (EPA-453/R07-004), "Control Techniques Guidelines for Miscellaneous Metal and Plastic Parts Coatings" (EPA-453/R-08-003), and "Control Techniques Guidelines For Paper, Film, and Foil Coatings" (EPA-453/R-07-003). The County has committed to correct the EPA's identified deficiencies, and ADEQ has committed to submit the updated rule within one year of the EPA's final conditional approval. If the District corrects the identified deficiencies and the EPA approves the updated rule, the District will have met its RACT obligation for this rule, and the associated CTGs. We do not propose to act on Rule 336 in this action.
 On February 26, 2020 (85 FR 10986), the EPA conditionally approved Rules 350, 351, 352, and 353 into the SIP, and also conditionally approved the associated CTG source categories for the County's 2016 RACT SIP: Control of Volatile Organic Emissions from Storage of Petroleum Liquids in Fixed-Roof Tanks (EPA - 450/ 2 - 77 - 036), Control of Volatile Organic Emissions from Petroleum Liquid Storage in External Floating Roof Tanks (EPA - 450/2 - 78 - 047), Control of Hydrocarbons from Tank Truck Gasoline Loading Terminals (EPA - 450/2 - 77 - 026), Control of Volatile Organic Emissions from Bulk Gasoline Plants (EPA - 450/2 - 77 - 035), Control of Volatile Organic Compound Leaks from Gasoline Tank Trucks and Vapor Collection Systems (EPA - 450/2 - 78 - 051), and Design Criteria for Stage I Vapor Control Systems -- Gasoline Service Stations (EPA - 450/R - 75 - 102).  The County has committed to correct the EPA's identified deficiencies, and ADEQ has committed to submit the updated rules within one year of the EPA's final conditional approval. If the County corrects the identified deficiencies and the EPA approves the updated rules, the County will have met its RACT obligation for these rules, and the associated CTGs. We do not propose to act on rules 350, 351, 352, and 353, or the associated CTGs in the County's 2016 RACT SIP in this action.
 On July 20, 2020 (85 FR 43692), the EPA conditionally approved Rules 323 and 324 into the SIP and disapproved Rule 322. The EPA did not act on the major NOx portion of the County's 2016 RACT SIP in this action. The County has committed to correct the EPA's identified deficiencies in rules 323 and 324, and ADEQ has committed to submit the updated rules within one year of the EPA's final conditional approval. If the County corrects the identified deficiencies and the EPA approves the updated rules, the County will have met its RACT obligation for the sources covered by rules 323 and 324. However, because Rule 322 has been disapproved, the County has not established RACT level controls for the major sources covered by this rule. Therefore, in the present action, the EPA is proposing to disapprove the County's RACT obligation for major sources of NOx.
 The present action  -  which is acting on the remaining elements of the 2016 RACT SIP.

 CONCLUSION

Based on our evaluation, the EPA staff recommends proposing partial approval and partial disapproval of the 2016 RACT SIP for the RACT demonstration for all source categories except those identified in section IV.2 and IV.3, above.

We recommend a disapproval on the negative declaration for the CTG categories of Industrial Adhesives and Aerospace, and an approval of the other submitted negative declarations.

In addition, we recommend an approval of the 2016 RACT SIP for sources associated with the following CTGs, because MCAQD has demonstrated that SIP-approved rules regulating these sources implement RACT levels of control: "Control of Volatile Organic Emissions from Solvent Metal Cleaning" (EPA-450/2-77-022), "Control Techniques Guidelines: Industrial Cleaning Solvents" (EPA-453/R-06-001), "Control of Volatile Organic Emissions from Existing Stationary Sources- Volume VIII: Graphic Arts- Rotogravure and Flexography" (EPA-430/2-78-033), "Offset Lithographic Printing and Letterpress Printing" (EPA-453/R06-002), and "Control of Volatile Organic Compound Emissions from Wood Furniture Manufacturing Operations" (EPA-453/R-96-007).

Finally, we recommend proposing approval for the RACT requirement for major non-CTG VOC sources, and a disapproval for major NOx sources. The MCAQD has identified all major sources of NOx and VOCs in the county, within the nonattainment area.  For VOCs, MCAQD has demonstrated that each of these sources is regulated by a SIP-approved rule that implements RACT-level controls, with the exception of one major source, which is a CTG source that is regulated by rules 350 and 351. Because all non-CTG major sources of VOC are regulated by RACT-level rules, we recommend approval for the major non-CTG VOC category.

For major NOx sources, although MCAQD has identified the appropriate universe of sources, it has not demonstrated that all of these sources are regulated by SIP-approved rules implementing RACT-level controls. On July 20, 2020, the EPA disapproved MCAQD Rule 322 and conditionally approved Rules 323 and 324 based on a limited number of deficiencies.  MCAQD has committed to address the deficiencies in rules 323 and 324, and submit rule amendments to ADEQ to submit to the EPA within one year of the EPA's final conditional approval. However, because Rule 322 was disapproved, the County has not established RACT level controls for the major sources covered by this rule.  Because there are not SIP-approved RACT level controls for all the identified major NOx sources, the RACT requirement for major NOx sources is not fulfilled and we are proposing disapproval for major NOx sources.
Table 4 below lists the CTGs, how MCAQD addressed this category in their 2016 RACT SIP submittal- with the rule or negative declaration corresponding to the CTG, and the EPA's proposed action for the source category, for those categories included within this rulemaking. Table 5 indicates whether major non-CTG VOC and NOx sources in the MCAQD are regulated by RACT rules.
