I. Background

A. Delegation of NESHAP

    Section 112(l) of the Clean Air Act, as amended in 1990 (CAA), 
authorizes EPA to delegate to state or local air pollution control 
agencies the authority to implement and enforce the standards set out 
in the Code of Federal Regulations, Title 40 (40 CFR), part 63, 
National Emission Standards for Hazardous Air Pollutants for Source 
Categories. On November 26, 1993, EPA promulgated regulations, codified 
at 40 CFR part 63, Subpart E (hereinafter referred to as ``Subpart 
E''), establishing procedures for EPA's approval of state rules or 
programs under section 112(l) (see 58 FR 62262). Subpart E was later 
amended on September 14, 2000 (see 65 FR 55810).
    Any request for approval under CAA section 112(l) must meet the 
approval criteria in 112(l)(5) and Subpart E. To streamline the 
approval process for future applications, a state or local agency may 
submit a one-time demonstration that it has adequate authorities and 
resources to implement and enforce any CAA section 112 standards. If 
such demonstration is approved, then the state or local agency would no 
longer need to resubmit a demonstration of these same authorities and 
resources for every subsequent request for delegation of CAA section 
112 standards. However, EPA maintains the authority to withdraw its 
approval if the State does not adequately implement or enforce an 
approved rule or program.

B. ADEQ Delegations

    On July 17, 1998, EPA published a direct final action delegating to 
the Arizona Department of Environmental Quality (ADEQ) several NESHAP 
and approving ADEQ's delegation mechanism for future standards (see 63 
FR 38478). That action explained the procedure for EPA to grant 
delegations to ADEQ by letter, with periodic Federal Register listings 
of standards that have been delegated. On April 17, 2008, ADEQ 
requested delegation of the following NESHAP contained in 40 CFR part 
63:
     Subpart DDDD--NESHAP: Plywood and Composite Wood Products
     Subpart DDDDD--NESHAP for Industrial, Commercial, and 
Institutional Boilers and Process Heaters
    On June 4, 2008, EPA granted delegation to ADEQ for these NESHAP, 
along with any amendments to previously-delegated NESHAP, as of July 1, 
2006. Today's action is serving to notify the public of the June 4, 
2008, delegations and to codify these delegations into the Code of 
Federal Regulations.

C. PDEQ Delegations

    On June 28, 1999, EPA published a direct final action delegating to 
the Pima County Department of Environmental Quality (PDEQ) several 
NESHAP and approving PDEQ's delegation mechanism for future standards 
(see 64 FR 34560). That action explained the procedure for EPA to grant 
delegations to PDEQ by letter, with periodic Federal Register listings 
of standards that have been delegated. On May 23, 2008, PDEQ requested 
delegation of the following NESHAP contained in 40 CFR part 63:
     Subpart J--NESHAP for Polyvinyl Chloride and Copolymers 
Production
     Subpart MM--NESHAP for Chemical Recovery Combustion 
Sources at Kraft, Soda, Sulfite, and Stand-Alone Semichemical Pulp 
Mills
     Subpart XX--National Emission Standards for Ethylene 
Manufacturing Process Units: Heat Exchange Systems and Waste Operations
     Subpart DDDD--NESHAP: Plywood and Composite Wood Products
     Subpart WWWWW--National Emission Standards for Hospital 
Ethylene Oxide Sterilizers
     Subpart YYYYY--NESHAP for Area Sources: Electric Arc 
Furnace Steelmaking Facilities
     Subpart ZZZZZ--NESHAP for Iron and Steel Foundries Area 
Sources
     Subpart BBBBBB--NESHAP for Source Category: Gasoline 
Distribution Bulk Terminals, Bulk Plants, and Pipeline Facilities
     Subpart CCCCCC--NESHAP for Source Category: Gasoline 
Dispensing Facilities
     Subpart DDDDDD--NESHAP for Polyvinyl Chloride and 
Copolymers Production Area Sources
     Subpart EEEEEE--NESHAP for Primary Copper Smelting Area 
Sources
     Subpart FFFFFF--NESHAP for Secondary Copper Smelting Area 
Sources
     Subpart GGGGGG--NESHAP for Primary Nonferrous Metals Area 
Sources--Zinc, Cadmium, and Beryllium
     Subpart HHHHHH--NESHAP: Paint Stripping and Miscellaneous 
Surface Coating Operations at Area Sources
     Subpart LLLLLL--NESHAP for Acrylic and Modacrylic Fibers 
Production Area Sources
     Subpart MMMMMM--NESHAP for Carbon Black Production Area 
Sources
     Subpart NNNNNN--NESHAP for Chemical Manufacturing Area 
Sources: Chromium Compounds
     Subpart OOOOOO--NESHAP for Flexible Polyurethane Foam 
Production and Fabrication Area Sources
     Subpart PPPPPP--NESHAP for Lead Acid Battery Manufacturing 
Area Sources
     Subpart QQQQQQ--NESHAP for Wood Preserving Area Sources

[[Page 47548]]

     Subpart RRRRRR--NESHAP for Clay Ceramics Manufacturing 
Area Sources
     Subpart SSSSSS--NESHAP for Glass Manufacturing Area 
Sources
     Subpart TTTTTT--NESHAP for Secondary Nonferrous Metals 
Processing Area Sources
    On June 16, 2008, EPA granted delegation to PDEQ for these NESHAP, 
along with any amendments to previously-delegated NESHAP, as of 
February 1, 2008. Today's action is serving to notify the public of the 
June 16, 2008, delegations and to codify these delegations into the 
Code of Federal Regulations.

II. EPA Action

    Today's document serves to notify the public of the delegation of 
NESHAP to ADEQ on June 4, 2008, and to PDEQ on June 16, 2008. Today's 
action will codify these delegations into the Code of Federal 
Regulations.

III. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
delegation request that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7412(l); 40 CFR 63.91(b). 
Thus, in reviewing state delegation submissions, our role is to approve 
state choices, provided that they meet the criteria of the CAA. 
Accordingly, this action merely updates the list of approved 
delegations in the Code of Federal Regulations and does not impose 
additional requirements beyond those imposed by state law. For that 
reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the delegation submission is not approved to apply in Indian 
country located in the state, and EPA notes that it will not impose 
substantial direct costs on tribal governments or preempt tribal law.
    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. EPA will submit a report containing this action 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).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by October 14, 2008. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements (see section 307(b)(2)).
