I. Background

A. Delegation of NESHAPs

    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

[[Page 36679]]

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. Maricopa County Delegations

    On October 30, 1996, EPA approved the Maricopa County Air Quality 
Department's program for accepting delegation of CAA section 112 
standards that are unchanged from Federal standards as promulgated (see 
61 FR 55910). On March 2, 2000, EPA published a direct final action 
delegating to Maricopa County several NESHAPs (see 65 FR 11231). That 
action explained the procedure for EPA to grant future delegations to 
Maricopa by letter, with periodic Federal Register listings of 
standards that have been delegated. On April 21, 2006, Maricopa 
requested delegation of the following NESHAPs contained in 40 CFR Part

[[Page 36680]]

    On May 16, 2006, EPA granted delegation to Maricopa County for 
these NESHAPs, along with any amendments to previously-delegated 
NESHAPs, as of July 1, 2004. Today's action is serving to notify the 
public of the May 16, 2006, delegation and to codify these delegations 
into the Code of Federal Regulations.
    Maricopa County also included a request for delegation of the 
Federal List of Hazardous Air Pollutants, Petitions Process, Lesser 
Quantity Designations, Source Category List codified at 40 CFR Part 63, 
Subpart C. This Subpart does not need to be delegated under the Clean 
Air Act section 112(l) approval process. EPA does not delegate to state 
or local agencies the authority to make changes to this Federal list of 
pollutants, and Subpart C does not contain any provisions or 
authorities requiring implementation by state or local agencies. As a 
result, EPA is not taking action to delegate 40 CFR Part 63, Subpart C 
or its amendments to Maricopa County.

C. San Joaquin Valley Delegations

    On September 28, 2004, the San Joaquin Valley Unified Air Pollution 
Control District (SJVUAPCD) requested, through the California Air 
Resources Board, delegation of authority to implement and enforce a 
number of 40 CFR Part 61 and Part 63 NESHAP as they apply to area 
sources. The request was limited to standards that were incorporated by 
reference in SJVUAPCD Rule 4002, amended on May 20, 2004. The 
delegation request was also limited in scope to area sources because 
the delegation of these standards had already been granted with respect 
to major sources.
    On October 31, 2005, EPA granted to SJVUAPCD the delegation of 40 
CFR Part 63 NESHAP that are applicable to area sources and incorporated 
by reference in SJVUAPCD Rule 4002, as amended on May 20, 2004. The 
delegation did not include any standards that are not incorporated by 
reference in the May 20, 2004, version of Rule 4002. If Rule 4002 is 
amended in the future, SJVUAPCD will need to submit a new request for 
delegation of any area source NESHAP that are newly incorporated into 
Rule 4002. Today's action is serving to notify the public of the 
October 31, 2005, delegations and to codify these delegations into the 
Code of Federal Regulations.

D. NDEP Delegations

    On May 27, 1998, EPA published a direct final action delegating to 
the Nevada Division of Environmental Protection (NDEP) several NESHAPs 
and approving NDEP's delegation mechanism for future standards (see 63 
FR 28906). That action explained the procedure for EPA to grant 
delegations to NDEP by letter, with periodic Federal Register listings 
of standards that have been delegated. On April 4, 2006, NDEP requested 
delegation of the following 40 CFR Part 63 NESHAPs and amendments:

     Amendments to Subpart LL--NESHAP for Primary Aluminum 
Production Plants, as published in 70 FR 66280 (November 2, 2005)
     Amendments to Subpart EEE--NESHAP for Hazardous Waste 
Combustors, as published in 70 FR 59401 (October 12, 2005)
     Amendments to Subpart QQQ--NESHAP for Primary Copper 
Smelting, as published in 70 FR 40672 (July 14, 2005)
     Amendments to Subpart RRR--NESHAP for Secondary 
Aluminum Production, as published in 70 FR 57513 (October 3, 2005)
     Subpart FFFF--NESHAP: Miscellaneous Organic Chemical 
Manufacturing, as published in 70 FR 38553 (July 1, 2005) and 
amended in 70 FR 51269 (August 30, 2005)
     Amendments to Subpart UUUU--NESHAP for Cellulose 
Products Manufacturing, as published in 70 FR 46683 (August 10, 
2005)
     Amendments to Subpart WWWW--NESHAP: Reinforced Plastic 
Composites Production, as published in 70 FR 50117 (August 25, 2005)
     Amendments to Subpart CCCCC--NESHAP for Coke Ovens: 
Pushing, Quenching, and Battery Stacks, as published in 70 FR 44285 
(August 2, 2005)
     Subpart EEEEE--NESHAP for Iron and Steel Foundries, as 
published in the July 1, 2005, Code of Federal Regulations

    On May 9, 2006, EPA granted delegation to NDEP for these NESHAPs, 
along with any amendments to previously-delegated NESHAPs, as of July 
1, 2005. Today's action is serving to notify the public of the May 9, 
2006, delegations and to codify these delegations into the Code of 
Federal Regulations.
    NDEP also included a request for delegation of amendments to the 
regulations implementing CAA sections 112(g) and 112(j), codified at 40 
CFR Part 63, Subpart B. These requirements need not be delegated under 
the section 112(l) approval process. When promulgating the regulations 
implementing section 112(g), EPA stated its view that ``the Act 
directly confers on the permitting authority the obligation to 
implement section 112(g) and to adopt a program which conforms to the 
requirements of this rule. Therefore, the permitting authority need not 
apply for approval under section 112(l) in order to use its own program 
to implement section 112(g)'' (see 61 FR 68397). Similarly, when 
promulgating the regulations implementing section 112(j), EPA stated 
its belief that ``section 112(l) approvals do not have a great deal of 
overlap with the section 112(j) provision, because section 112(j) is 
designed to use the title V permit process as the primary vehicle for 
establishing requirements'' (see 59 FR 26447). Therefore, state or 
local agencies implementing the requirements under sections 112(g) and 
112(j) do not need approval under section 112(l). As a result, EPA is 
not taking action to delegate 40 CFR Part 63, Subpart B, to NDEP.

II. EPA Action

    Today's document serves to notify the public of the delegation of 
NESHAPs to Maricopa County on May 16, 2006, to SJVUAPCD on October 31, 
2005, and to NDEP on May 9, 2006. Today's action will codify these 
delegations into the Code of Federal Regulations.

III. Administrative Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. For this 
reason, this action is also not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action 
merely updates the list of approved delegations in the Code of Federal 
Regulations and imposes no additional requirements. Accordingly, the 
Administrator certifies that this rule will not have a significant 
economic impact on a substantial number of small entities under the 
Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule 
does not impose any additional enforceable duty beyond that required by 
state law, it does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4).
    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000). This action also does not have Federalism 
implications because it does not have substantial direct effects on the 
States, on the relationship between the national government and the 
States, or on the distribution of power and responsibilities among the 
various

[[Page 36681]]

levels of government, as specified in Executive Order 13132 (64 FR 
43255, August 10, 1999). This action merely updates the list of 
already-approved delegations, and does not alter the relationship or 
the distribution of power and responsibilities established in the CAA. 
This rule also is not subject to Executive Order 13045 ``Protection of 
Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997), because it is not economically significant.
    In reviewing state delegation submissions, our role is to approve 
state choices, provided that they meet the criteria of the CAA. In this 
context, in the absence of a prior existing requirement for the State 
to use voluntary consensus standards (VCS), EPA has no authority to 
disapprove state submissions for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a state 
submission, to use VCS in place of a state submission that otherwise 
satisfies the provisions of the CAA. Thus, the requirements of section 
12(d) of the National Technology Transfer and Advancement Act of 1995 
(15 U.S.C. 272 note) do not apply. This rule does not impose an 
information collection burden under the provisions of the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    The Congressional Review Act, 5 U.S.C. section 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 
rule 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. 
section 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 August 28, 2006. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule 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)).
