Delegation of National Emission Standards for Hazardous Air

Pollutants for Source Categories; State of Arizona, Arizona Department of Environmental Quality, Pima County Department of Environmental

Quality

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

SUMMARY: EPA is amending certain regulations to reflect the current delegation status of national emission standards for hazardous air pollutants (NESHAP) in Arizona. Several NESHAP were delegated to the

Arizona Department of Environmental Quality on June 4, 2008, and to the

Pima County Department of Environmental Quality on June 16, 2008. The purpose of this action is to update the listing in the Code of Federal

Regulations.

DATES: This rule is effective on October 14, 2008, without further notice, unless EPA receives adverse comments by September 15, 2008. If we receive such comments, we will publish a timely withdrawal in the

Federal Register to notify the public that this direct final rule will not take effect.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR- 2008-0555, by one of the following methods:

  4. Background

    1. 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.

    2. 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.

    3. 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

      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.

  5. 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.

  6. 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)).
