40 CFR Part 52
[AZ17-1-6090; FRL-4847-9]
Approval and Promulgation of Implementation Plans; Arizona State
Implementation Plan Revision, Maricopa County Air Pollution Control
Division
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve revisions to the Arizona State
Implementation Plan (SIP) adopted by the Maricopa County Air Pollution
Control Division (MCAPCD) on April 6, 1992 and November 16, 1992. The
Arizona Department of Environmental Quality (DEQ) submitted these
revisions to EPA on June 29, 1992 and February 4, 1993. The revisions
concern MCAPCD's Rule 350, Storage of Organic Liquids at Bulk Plants
and Terminals; Rule 351, Loading of Organic Liquids; Rule 352, Gasoline
Delivery Vessels, and a new rule, Rule 337, Graphic Arts. These rules
control volatile organic compound (VOC) emissions from printing
materials, and from the storage, loading, and transport of organic
liquids including gasoline. The intended effect of proposing approval
of these rules is to regulate emissions of VOCs in accordance with the
requirements of the Clean Air Act, as amended in 1990 (CAA or the Act).
EPA's final action on this notice of proposed rulemaking (NPR) will
incorporate these rules into the federally approved SIP. EPA has
evaluated each of these rules and is proposing to approve them under
provisions of the CAA regarding EPA action on SIP submittals, SIPs for
national primary and secondary ambient air quality standards and plan
requirements for nonattainment areas.
DATES: Comments must be received on or before April 11, 1994.
ADDRESSES: Comments may be mailed to: Daniel A. Meer, Chief, Rulemaking
Section (A-5-3), Air and Toxics Division, U.S. Environmental Protection
Agency, Region 9, 75 Hawthorne Street, San Francisco, CA 94105.

SUPPLEMENTARY INFORMATION:
Background
On March 3, 1978, EPA promulgated a list of ozone nonattainment
areas under the provisions of the Clean Air Act, as amended in 1977
(1977 CAA or pre-amended Act), that included Maricopa County. 43 FR
8964, 40 CFR 81.303. On March 19, 1979, EPA changed the name and
modified the geographic boundaries of the ozone nonattainment area of
Maricopa Country to the Maricopa Association of Governments (MAG) Urban
Planning Area. 44 FR 16391, 40 CFR 81.303. On February 24, 1984, EPA
notified the Governor of Arizona, pursuant to section 110(a)(2)(H) of
the pre-amended Act, that MCAPCD's portion of the Arizona SIP was
inadequate to attain and maintain the ozone standard and requested that
deficiencies in the existing SIP be corrected (EPA's SIP-Call, 49 FR
18827, May 3, 1984). On May 26, 1988, EPA again notified the Governor
of Arizona that MCAPCD's portion of the Arizona SIP was inadequate to
attain and maintain the ozone standard and requested that deficiencies
relating to VOC controls and the application of reasonably available
control technology (RACT) in the existing SIP be corrected (EPA's
second SIP-Call, 53 FR 34500, September 7, 1988). On November 15, 1990,
the Clean Air Act Amendments of 1990 were enacted. Public Law 101-549,
104 Stat. 2399, codified at 42 U.S.C. 7401-7671q. In amended section
182(a)(2)(A) of the CAA, Congress statutorily adopted the requirement
that nonattainment areas fix their deficient RACT rules for ozone and
established a deadline of May 15, 1991 for states to submit corrections
of those deficiencies.
Section 182(a)(2)(A) applies to areas designated as nonattainment
prior to enactment of the amendments and classified as marginal or
above as of the date of enactment. It requires such areas to adopt and
correct RACT rules pursuant to pre-amended section 172(b) as
interpreted in pre-amended guidance.1 EPA's SIP-Calls used that
guidance to indicate the necessary corrections for specific
nonattainment areas. The MAG Urban Planning Area is classified as
moderate2; therefore, this area was subject to the RACT fix-up
requirement and the May 15, 1991 deadline.
---------------------------------------------------------------------------
\1\Among other things, the pre-amended guidance consists of
those portions of the proposed post-1987 ozone and carbon monoxide
policy that concern RACT, 52 FR 45044 (November 24, 1987); ``Issues
Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations,
Clarification to Appendix D of November 24, 1987 Federal Register
Notice'' (Blue Book) (notice of availability was published in the
Federal Register on May 25, 1988); and the existing control
technique guidelines (CTGs).
\2\The MAG Urban Planning Area retained its designation of
nonattainment and was classified by operation of law pursuant to
sections 107(d) and 181(a) upon the date of enactment of the CAA.
See 55 FR 56694 (November 6, 1991).
---------------------------------------------------------------------------
The State of Arizona submitted several revised RACT rules for
incorporation into its SIP on June 29, 1992 and February 4, 1993,
including the rules being acted on in this document. This document
addresses EPA's proposed action for MCAPCD's Rule 350, Storage of
Organic Liquids at Bulk Plants and Terminals; Rule 351, Loading of
Organic Liquids; Rule 352, Gasoline Delivery Vessels; and Rule 337,
Graphic Arts. The submitted Rules 350, 351, and 337 were found to be
complete on September 8, 1992, while Rule 352 was found to be complete
on March 10, 1993, pursuant to EPA's completeness criteria that are set
forth in 40 CFR part 51, appendix V3. The rules are being proposed
for approval into the SIP. Arizona's complete submittal of Rules 350,
351, and 337 satisfies the deficiency for which a finding of
nonsubmittal, dated October 22, 1991, was made and stopped the
sanctions clock. However, the Federal Implementation Plan (FIP) clock
will not stop until EPA approves the rules.
---------------------------------------------------------------------------
\3\EPA adopted the completeness criteria on February 16, 1990
(55 FR 5830) and, pursuant to section 110(k)(1)(A) of the CAA,
revised the criteria on August 26, 1991 (56 FR 42216).
---------------------------------------------------------------------------
Rules 350 and 351 control VOC emissions from the storage and
loading of organic liquids including gasoline. Rule 352 controls VOC
emissions from gasoline delivery tanks, while Rule 337 controls VOC
emissions from graphic art materials, such as inks. VOCs contribute to
the production of ground level ozone and smog. The rules were adopted
as part of the division's efforts to achieve the National Ambient Air
Quality Standard (NAAQS) for ozone and in response to EPA's SIP-Calls
and the section 182(a)(2)(A) CAA requirement. The following is EPA's
evaluation and proposed action for these rules.
EPA Evaluation and Proposed Action
In determining the approvability of a VOC rule, EPA must evaluate
the rule for consistency with the requirements of the CAA and EPA
regulations, as found in section 110 and part D of the CAA and 40 CFR
part 51 (Requirements for Preparation, Adoption, and Submittal of
Implementation Plans). The EPA interpretation of these requirements,
which forms the basis for today's action, appears in the various EPA
policy guidance documents listed in footnote 1. Among those provisions
is the requirement that a VOC rule must, at a minimum, provide for the
implementation of RACT for stationary sources of VOC emissions. This
requirement was carried forth from the pre-amended Act.
For the purpose of assisting state and local agencies in developing
RACT rules, EPA prepared a series of Control Technique Guideline (CTG)
documents. The CTGs are based on the underlying requirements of the Act
and specify the presumptive norms for what is RACT for specific source
categories. Under the CAA, Congress ratified EPA's use of these
documents, as well as other Agency policy, for requiring States to
``fix-up'' their RACT rules. See section 182(a)(2)(A). The CTGs
applicable to Rule 350 are: (1) CTG EPA-450/2-77-035, Control of
Volatile Organic Emissions from Bulk Gasoline Plants; (2) CTG EPA-450/
2-78-047, Control of Volatile Organic Emissions from Petroleum Liquid
Storage in External Floating Roof Tanks, and (3) CTG EPA-450/2/77-036,
Control of Volatile Organic Emissions from Storage of Petroleum Liquids
in Fixed-Roof Tanks. The CTGs applicable to Rule 351 are: (1) CTG EPA-
450/2-77-035, Control of Volatile Organic Emissions from Bulk Gasoline
Plants; and (2) CTG EPA-450/2-77-026, Control of Hydrocarbons from Tank
Truck Gasoline Loading Terminals. The CTG document applicable to Rule
352 is CTG EPA 450/2-78-022, Control of Volatile Organic Compound Leaks
from Gasoline Tank Trucks. Finally, the documents which apply to Rule
337 are: (1) CTG EPA-450/2-78-033, Control of Volatile Organic
Emissions from Existing Stationary Sources, Volume VIII: Graphic Arts-
Rotogravure and Flexography; and (2) the document entitled
``Recordkeeping Guidance Document for Surface Coating Operations and
the Graphic Arts Industry'' (EPA 340/1-88-003). Further interpretations
of EPA policy are found in the Blue Book, referred to in footnote 1. In
general, these guidance documents have been set forth to ensure that
VOC rules are fully enforceable and strengthen or maintain the SIP.
MCAPCD's Rule 350, Storage of Organic Liquids at Bulk Plants and
Terminals, includes the following significant changes from the current
SIP:
1. Applicability of the rule is specific to storage of organic
liquids.
2. A definitions section has been added.
3. Standards for floating roofs and requirements for seals and
fabric of the roofs have been added.
4. Recordkeeping and inspection provisions have been added.
5. A compliance schedule with full compliance by 18 months has been
added.
6. Provisions for records on stored liquids including their vapor
pressures have been added.
7. Test methods for determining compliance have been added.
MCAPCD's Rule 351, Loading of Organic Liquids, includes the
following significant changes from the current SIP:
1. A definitions section has been added.
2. Standards have been added limiting emissions to 0.29 pounds of
VOC per 1,000 gallons of liquid transferred.
3. Operating, repair, and testing requirements have been added.
4. Exemption of tanks with liquids which were not for sale has been
deleted. Recordkeeping provisions for other exempt tanks have been
added.
5. Annual leak detection tests and monthly visual leak monitoring
are now required, and the leak test method has been clarified.
6. A compliance schedule requiring full compliance within 18 months
has been added.
7. Test methods for determining compliance with the emission limits
and vapor pressure limits have been added.
MCAPCD's Rule 352, Gasoline Delivery Vessels, includes the
following significant changes from the current SIP:
1. A definitions section has been added.
2. Standards for vapor tightness of the delivery vessels and test
methods to use in the determination have been added.
3. Provisions for registering and identifying tanks which pass the
vapor tightness test have been added.
4. Provisions for recordkeeping have also been added.
MCAPCD's Rule 337, Graphic Arts, is a new rule and contains the
following significant standards: (1) VOC content of graphic art
materials is limited to 2.5 lbs/gal; (2) overall control efficiency of
65% for noncompliant materials is required; and (3) graphic materials
sold are required to be labeled with the VOC content. There are also
provisions for monitoring and for recordkeeping and reporting.
EPA has evaluated the submitted rules and has determined that they
are consistent with the CAA, EPA regulations, and EPA policy.
Therefore, MCAPCD's Rules 350, Storage of Organic Liquids at Bulk
Plants and Terminals; 351, Loading of Organic Liquids; 352, Gasoline
Delivery Vessels; and 337, Graphic Arts, are being proposed for
approval under section 110(k)(3) of the CAA as meeting the requirements
of section 110(a) and part D.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any state implementation plan. Each request for revision to
the state implementation plan shall be considered separately in light
of specific technical, economic, and environmental factors and in
relation to relevant statutory and regulatory requirements.
Regulatory Process
Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA
must prepare a regulatory flexibility analysis assessing the impact of
any proposed or final rule on small entities. 5 U.S.C. 603 and 604.
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small businesses, small not-for-profit enterprises and
government entities with jurisdiction over populations of less than
50,000.
SIP approvals under sections 110 and 301 and subchapter I, part D
of the CAA do not create any new requirements, but simply approve
requirements that the State is already imposing. Therefore, because the
Federal SIP-approval does not impose any new requirements, it does not
have a significant impact on any small entities affected. Moreover, due
to the nature of the Federal-state relationship under the CAA,
preparation of a regulatory flexibility analysis would constitute
Federal inquiry forbids EPA to base its actions concerning SIPs on such
grounds. into the economic reasonableness of state action. The CAA
Union Electric Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 (S.Ct. 1976);
42 U.S.C. 7410(a)(2).
This action has been classified as a Table 2 action by the Regional
Administrator under the procedures published in the Federal Register on
January 19, 1989 (54 FR 2214-2225), as revised by an October 4, 1993,
memorandum from Michael H. Shapiro, Acting Assistant Administrator for
Air and Radiation. A future notice will inform the general public of
these tables. On January 6, 1989, the Office of Management and Budget
(OMB) waived Table 2 and Table 3 SIP revisions (54 FR 222) from the
requirements of Section 3 of Executive Order 12291 for 2 years. The EPA
has submitted a request for a permanent waiver for Table 2 and Table 3
SIP revisions. The OMB has agreed to continue the waiver until such
time as it rules on EPA's request. This request continues in effect
under Executive Order 12866 which superseded Executive Order 12291 on
September 30, 1993.
