ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 63

[FRL-6545-2]


Delegation of National Emission Standards for Hazardous Air 
Pollutants for Source Categories; State of Arizona; Arizona Department 
of Environmental Quality; Maricopa County; Environmental Services 
Department

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is taking direct final action to delegate the authority to 
implement and enforce specific national emission standards for 
hazardous air pollutants (NESHAPs) to the Maricopa County Environmental 
Services Department (MC) in Arizona. The preamble outlines the process 
that MC will use to receive delegation of any future NESHAPs, and 
identifies the NESHAP categories to be delegated by today's action. EPA 
has reviewed MC's request for delegation and has found that this 
request satisfies all of the requirements necessary to qualify for 
approval. Thus, EPA is hereby granting MC the authority to implement 
and enforce the unchanged NESHAP categories listed in this rule. This 
action is also notifying the public of additional NESHAPs that were 
delegated to the Arizona Department of Environmental Quality (ADEQ) on 
November 10, 1999.

DATES: This rule is effective on May 1, 2000, without further notice, 
unless EPA receives relevant adverse comments by April 3, 2000. If EPA 
receives such comment, then it will publish a timely withdrawal in the 
Federal Register informing the public that this rule will not take 
effect.

ADDRESSES: Comments must be submitted to Andrew Steckel at the Region 
IX office listed below. Copies of the request for delegation and other 
supporting documentation are available for public inspection (docket 
number A-96-25) at the following location:
    U.S. Environmental Protection Agency, Region IX, Rulemaking Office 
(AIR-4), Air Division, 75 Hawthorne Street, San Francisco, California 
94105-3901.

FOR FURTHER INFORMATION CONTACT: Mae Wang, Rulemaking Office (AIR-4), 
Air Division, U.S. Environmental Protection Agency, Region IX, 75

SUPPLEMENTARY INFORMATION:

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 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).
    Any request for approval under CAA section 112(l) must meet the 
approval criteria in 112(l)(5) and 40 CFR Part 63, Subpart E. To 
streamline the approval process for future applications, a state or

[[Page 11232]]

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 Delegation Request

    On October 30, 1996, EPA approved the Maricopa County Environmental 
Services Department's (MC's) program for accepting delegation of 
section 112 standards that are unchanged from Federal standards as 
promulgated (see 61 FR 55910). The approved program reflects an 
adequate demonstration by MC of general resources and authorities to 
implement and enforce section 112 standards. However, formal delegation 
for an individual standard does not occur until MC obtains the 
necessary regulatory authority to implement and enforce that particular 
standard, and EPA approves MC's formal delegation request for that 
standard.
    MC informed EPA that it intends to obtain the regulatory authority 
necessary to accept delegation of section 112 standards by 
incorporating section 112 standards into local codes of regulation. The 
details of this delegation mechanism are set forth in a Memorandum of 
Agreement (MOA) between MC and EPA, and are available for public 
inspection at the U.S. EPA Region IX office (docket No. A-96-25).
    On February 1, 2000, MC requested delegation for several individual 
section 112 standards that have been incorporated by reference into the 
Maricopa County Air Pollution Control Regulations. The standards that 
are being delegated by today's action are listed in the table at the 
end of this rule.

C. ADEQ delegations

    On July 17, 1998, EPA published a direct final action delegating to 
ADEQ several NESHAPs 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 October 6, 
1999, ADEQ requested delegation of the following NESHAPs contained in 
40 CFR Part 63:
    Subpart S--NESHAP from the Pulp and Paper Industry
    Subpart LL--NESHAP for Primary Aluminum Reduction Plants
    Subpart EEE--NESHAP for Hazardous Waste Combustors
On November 10, 1999, EPA granted delegation to ADEQ for these NESHAPs. 
Today's action is serving to notify the public of the November 10, 
1999, delegation and to codify these delegations into the Code of 
Federal Regulations.

II. EPA Action

A. Delegation to Maricopa County for Specific Standards

    After reviewing MC's request for delegation of various NESHAPs, EPA 
has determined that this request meets all the requirements necessary 
to qualify for approval under CAA section 112(l) and 40 CFR 63.91. 
Accordingly, MC is granted the authority to implement and enforce the 
requested NESHAPs. These delegations will be effective on May 1, 2000. 
A table of the NESHAP categories that will be delegated to MC is shown 
at the end of this rule. Although MC will have primary implementation 
and enforcement responsibility, EPA retains the right, pursuant to CAA 
section 112(l)(7), to enforce any applicable emission standard or 
requirement under CAA section 112. In addition, EPA does not delegate 
any authorities that require implementation through rulemaking in the 
Federal Register, or where Federal overview is the only way to ensure 
national consistency in the application of the standards or 
requirements of CAA section 112.
    After a state or local agency has been delegated the authority to 
implement and enforce a NESHAP, the delegated agency becomes the 
primary point of contact with respect to that NESHAP. Pursuant to 40 
CFR sections 63.9(a)(4)(ii) and 63.10(a)(4)(ii), EPA Region IX waives 
the requirement that notifications and reports for delegated standards 
be submitted to EPA as well as to MC.
    In its February 1, 2000 request, MC included a request for 
delegation of the regulations implementing CAA section 112(i)(5), 
codified at 40 CFR Part 63, Subpart D. These requirements apply to 
state or local agencies that have a permit program approved under title 
V of the Act (see 40 CFR 63.70). MC received final interim approval of 
its title V operating permits program on October 30, 1996 (see 61 FR 
55910). State or local agencies implementing the requirements under 
Subpart D do not need approval under section 112(l). Therefore, EPA is 
not taking action to delegate 40 CFR Part 63, Subpart D to MC.
    MC also included a request for delegation of the regulations 
implementing CAA sections 112(g) and 112(j), codified at 40 CFR Part 
63, Subpart B. These requirements apply to major sources only, and 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 MC.

B. Maricopa's delegation mechanism for future standards

    Today's document serves to notify the public of the details of MC's 
procedure for receiving delegation of future NESHAPs. As set forth in 
the MOA, MC intends to incorporate by reference, into local codes of 
regulation, each newly promulgated NESHAP for which it intends to seek 
delegation. MC will then submit a letter to EPA Region IX, along with 
proof of regulatory authority, requesting delegation for each 
individual NESHAP. Region IX will respond in writing that delegation is 
either granted or denied. If a request is approved, the delegation of 
authorities will be considered effective upon the date of the response 
letter from Region IX. Periodically, EPA will publish in the Federal 
Register a listing of the standards that have been delegated. Although 
EPA reserves its right, pursuant to 40 CFR section 63.96, to review the 
appropriateness of any future delegation request, EPA will not 
institute any additional comment periods on these future delegation 
actions. Any parties interested in commenting on this procedure for 
delegating future unchanged NESHAPs should do so at this time.

[[Page 11233]]

C. Notice of Delegations to ADEQ

    Today's document serves to notify the public that on November 10, 
1999, EPA granted delegation to ADEQ for the following NESHAPs 
contained in 40 CFR Part 63:
     Subpart S--NESHAP from the Pulp and Paper Industry
     Subpart LL--NESHAP for Primary Aluminum Reduction Plants
     Subpart EEE--NESHAP for Hazardous Waste Combustors

Today's action will codify these delegations into the Code of Federal 
Regulations.

D. Opportunity for Public Comment

    EPA is publishing this rule without prior proposal because the 
Agency views this as a noncontroversial action and anticipates no 
adverse comments. However, in the Proposed Rules section of this 
Federal Register publication, EPA is publishing a separate document 
that will serve as the proposal for this action should relevant adverse 
comments be filed. This action will be effective May 1, 2000, without 
further notice unless the Agency receives relevant adverse comments by 
April 3, 2000.
    If EPA receives such comments, then EPA will publish a document 
withdrawing this final rule and informing the public that the rule will 
take effect. All public comments received will then be addressed in a 
subsequent final rule based on the proposed rule. EPA will not 
institute a second comment period on the rule. Any parties interested 
in commenting on the rule should do so at this time. If no such 
comments are received, the public is advised that this rule will be 
effective on May 1, 2000, and no further action will be taken on the 
proposed rule.

III. Administrative Requirements

A. Executive Orders 12866 and 13045

    The Office of Management and Budget has exempted this regulatory 
action from review under Executive Order 12866.
    This final rule is not subject to Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks,'' because it is not an ``economically significant'' action under 
Executive Order 12866.

B. Regulatory Flexibility Act

    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 economic 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.
    Delegations of authority to implement and enforce unchanged Federal 
standards under section 112(l) of the Clean Air Act do not create any 
new requirements but simply transfer primary implementation authorities 
to the State. Therefore, because this action does not impose any new 
requirements, the Administrator certifies that it does not have a 
significant impact on any small entities affected.

C. Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to state, local, or tribal governments in the aggregate, or to 
private sector, of $100 million or more. Under section 205, EPA must 
select the most cost-effective and least burdensome alternative that 
achieves the objectives of the rule and is consistent with statutory 
requirements. Section 203 requires EPA to establish a plan for 
informing and advising any small governments that may be significantly 
or uniquely impacted by the rule.
    EPA has determined that the delegation action promulgated does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either state, local, or tribal governments in the 
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under state or local law, and imposes no new 
Federal requirements. Accordingly, no additional costs to state, local, 
or tribal governments, or to the private sector, result from this 
action.

D. Submission to Congress and the General Accounting Office

    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 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. This rule is not a 
``major'' rule as defined by 5 U.S.C. 804(2).

E. Petitions for Judicial Review

    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 May 1, 2000. 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)).
