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. NDEP Delegations

    On May 27, 1998, EPA published a direct final action delegating to 
the NDEP several NESHAP and approving NDEP's delegation mechanism for 
future standards (see 63 FR 28906). That action explained the procedure 
for EPA to grant future delegations to NDEP by letter, with periodic 
Federal Register listings of standards that have been delegated. On 
August 19, 2011, NDEP requested delegation of the following NESHAP 
contained in 40 CFR part 63:
     The amendments to Subpart LLL--NESHAP from the Portland 
Cement Manufacturing Industry, as set forth in 75 FR 54970 (September 
9, 2010).
     The amendments to Subpart ZZZZ--NESHAP for Stationary 
Reciprocating Internal Combustion Engines, as set forth in 75 FR 51570 
(August 20, 2010) and 76 FR 12863 (March 9, 2011).
     Subpart DDDDD--NESHAP for Industrial, Commercial, and 
Institutional Boilers and Process Heaters.
     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 HHHHHH--NESHAP: Paint Stripping and Miscellaneous 
Surface Coating Operations at Area Sources.
     Subpart JJJJJJ--NESHAP for Industrial, Commercial, and 
Institutional Boilers Area Sources.
     Subpart VVVVVV--NESHAP for Chemical Manufacturing Area 
Sources.
     Subpart WWWWWW--NESHAP: Area Source Standards for Plating 
and Polishing Operations.
     Subpart XXXXXX--NESHAP Area Source Standards for Nine 
Metal Fabrication and Finishing Source Categories.
     Subpart ZZZZZZ--NESHAP: Area Source Standards for 
Aluminum, Copper, and Other Nonferrous Foundries.

[[Page 11391]]

     Subpart AAAAAAA--NESHAP for Area Sources: Asphalt 
Processing and Asphalt Roofing Manufacturing.
     Subpart BBBBBBB--NESHAP for Area Sources: Chemical 
Preparations Industry.
     Subpart CCCCCCC--NESHAP for Area Sources: Paints and 
Allied Products Manufacturing.
     Subpart EEEEEEE--NESHAP: Gold Mine Ore Processing and 
Production Area Source Category.
    On October 6, 2011, EPA granted delegation to NDEP for these 
NESHAP, along with any amendments made to previously-delegated NESHAP 
as of July 1, 2010. Today's action is serving to notify the public of 
the October 6, 2011, delegation 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 NDEP on October 6, 2011. Today's action will codify these 
delegations into the CFR.

III. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve delegation 
requests that comply with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7412(l); 40 CFR 63.91(b). Thus, in 
reviewing delegation submissions, EPA's role is to approve State 
choices, provided that they meet the criteria of the CAA. Accordingly, 
this action merely approves State law as meeting Federal requirements 
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 CAA; and
     Does not provide EPA with the discretionary authority to 
address disproportionate human health or environmental effects with 
practical, appropriate, 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 
delegations are 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 CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by April 27, 2012. 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. Parties with objections to this direct final rule are 
encouraged to file a comment in response to the parallel notice of 
proposed rulemaking for this action published in the Proposed Rules 
section of today's Federal Register, rather than file an immediate 
petition for judicial review of this direct final rule, so that EPA can 
withdraw this direct final rule and address the comment in the proposed 
rulemaking. This action may not be challenged later in proceedings to 
enforce its requirements (see section 307(b)(2)).

    Authority: This action is issued under the authority of Section 
112 of the Clean Air Act, as amended, 42 U.S.C. Section 7412.
