SUPPLEMENTARY INFORMATION:

I. Background

    On September 10, 1993, the Louisiana Department of Environmental 
Quality

[[Page 31036]]

(LDEQ) submitted to the EPA a SIP revision incorporating PAMS into the 
ambient air quality monitoring network of State or Local Air Monitoring 
Stations (SLAMS) and National Air Monitoring Stations (NAMS). The State 
will establish and maintain PAMS as part of its overall ambient air 
quality monitoring network.
    Section 182(c)(1) of the Act and the General Preamble 1 
require that the EPA promulgate rules for enhanced monitoring of ozone, 
oxides of nitrogen (NOX), and volatile organic compounds (VOC) no 
later than 18 months after the date of the enactment of the Act. In 
addition, the Act requires that, following the promulgation of the 
rules relating to enhanced ambient monitoring, the State must commence 
actions to adopt and implement a program, based on these rules, to 
improve monitoring for ambient concentrations of ozone, NOX and 
VOC and to improve monitoring of emissions of NOX and VOC.
---------------------------------------------------------------------------

    \1\ ``General Preamble for the Implementation of Title I of the 
Clean Air Act Amendments of 1990,'' 57 FR 13515, dated April 16, 
1992.
---------------------------------------------------------------------------

    The final PAMS rule was promulgated by the EPA on February 12, 1993 
(58 FR 8452). Section 58.40(a) of the rule requires the State to submit 
a PAMS network description, including a schedule for implementation, to 
the Administrator within six months after promulgation or by August 12, 
1993. Further, section 58.20(f) requires the State to provide for the 
establishment and maintenance of a PAMS network within nine months 
after promulgation of the final rule or by November 12, 1993.
    On July 1, 1993, the LDEQ submitted to the EPA a proposed SIP 
revision which included a PAMS network description. The LDEQ held a 
public hearing on the proposed PAMS SIP revision on August 23, 1993. No 
comments were received either during the public hearing or the public 
comment period with the exception of one written comment submitted by 
the EPA as discussed below.
    On September 10, 1993, the State submitted the official PAMS SIP 
revision. Louisiana's PAMS SIP revision is intended to meet the 
requirements of section 182(c)(1) of the Act and effect compliance with 
the PAMS regulations promulgated on February 12, 1993, and codified at 
40 CFR part 58.
    On September 27, 1993, the LDEQ submitted to the EPA a revised PAMS 
network description including a schedule for implementation. (The EPA 
conditionally approved the network description on April 21, 1994, and 
granted final approval of the network description on October 13, 1995.)
    It should be noted that, since network descriptions may change 
annually, they are not part of the SIP as recommended by the EPA's 
``Guideline for the Implementation of the Ambient Air Monitoring 
Regulations 40 CFR Part 58 (November 1979).'' The network description 
is negotiated and approved during an annual review as required by 40 
CFR sections 58.25, 58.36, and 58.46. EPA did, however, require States 
to provide a copy of the proposed PAMS network description, including 
phase-in schedule, on file for public inspection during the public 
notice/comment period for the PAMS SIP revision or, alternatively, 
provide information to the public upon request concerning the State's 
plans for implementing the rules. As stated earlier, Louisiana included 
a network description and implementation schedule in the proposed PAMS 
SIP revision.
    On November 17, 1993, the EPA sent the Governor of Louisiana a 
letter finding the September 10, 1993, PAMS SIP submittal 
administratively complete.

II. Analysis of State Submittal

    The Louisiana PAMS SIP revision will provide Louisiana with the 
authority to establish and operate the PAMS sites, secure State funds 
for PAMS and provide the EPA with the authority to enforce the 
implementation of PAMS, since their implementation is required by the 
Act.
    The criteria used to review the proposed SIP revision are derived 
from the PAMS regulations codified at 40 CFR Part 58; the EPA's 
``Guideline for the Implementation of the Ambient Air Monitoring 
Regulations 40 CFR part 58''; a September 2, 1993, memorandum from G. 
T. Helms, Office of Air Quality Planning and Standards, entitled, 
``Final Boilerplate Language for the PAMS SIP Submittal''; the Act; and 
the General Preamble.
    The Louisiana PAMS SIP revision provides that the State will 
implement PAMS as required in 40 CFR Part 58, as amended February 12, 
1993. The State will amend its SLAMS and its NAMS monitoring systems to 
include the PAMS requirements. It will develop its PAMS network design 
and establish monitoring sites pursuant to 40 CFR part 58 in accordance 
with an approved network description and as negotiated with the EPA 
through the section 105 grant process on an annual basis. To date, the 
State has successfully implemented a PAMS network as required in 40 CFR 
part 58.
    The Louisiana PAMS SIP revision also includes a provision to meet 
quality assurance requirements as contained in 40 CFR part 58, appendix 
A. The State also assures that the State's PAMS monitors will meet 
monitoring methodology requirements contained in 40 CFR part 58, 
appendix C. Lastly, the State assures that the Louisiana PAMS network 
will be phased in over a period of five years as required in 40 CFR 
58.44. The State's PAMS SIP submittal and the EPA's technical support 
document are available for viewing at the EPA Region 6 office and the 
LDEQ's Baton Rouge office as outlined under the ADDRESSES section of 
this FR document.
    The State addressed, in the final PAMS SIP submittal, EPA Region 
6's comment on the proposed SIP that the SIP should include a clear 
statement that the LDEQ intends to implement PAMS pursuant to 40 CFR 
part 58 as amended February 12, 1993.

III. Rulemaking Action

    In this action, the EPA is approving the revision to the Louisiana 
Ozone SIP for PAMS. The EPA has reviewed this revision to the Louisiana 
SIP and is approving it as submitted because it meets the requirements 
of section 182(c)(1) of the Act and the appropriate sections of 40 CFR 
part 58.
    Copies of the State's SIP revision and the Technical Support 
Document (TSD) detailing EPA's review of the SIP revision are available 
at the address listed in the ADDRESSES section above. For a detailed 
analysis of the SIP revision, the reader is referred to the TSD.
    The EPA is publishing this action without prior proposal because 
the Agency views this as a noncontroversial revision and anticipates no 
adverse comments. However, in a separate document in this Federal 
Register publication, the EPA is proposing to approve the SIP revision 
should adverse or critical comments be filed. Thus, today's direct 
final action will be effective August 19, 1996, unless by July 19, 
1996, adverse or critical comments are received.
    If the EPA receives such comments, this action will be withdrawn 
before the effective date by publishing a subsequent document that will 
withdraw the final action. All public comments received will then be 
addressed in a subsequent final rule based on this action serving as a 
proposed rule. The EPA will not institute a second comment period on 
this action. Any parties interested in commenting on this action should 
do so at this time. If no such comments are

[[Page 31037]]

received, the public is advised that this action will be effective 
August 19, 1996.
    The EPA has reviewed this request for revision of the federally-
approved SIP for conformance with the provisions of the Act as amended 
November 15, 1990. The EPA has determined that this action conforms 
with those requirements.
    Nothing in this action should be construed as permitting, allowing 
or establishing a precedent for any future request for revision to any 
SIP. Each request for revision to a SIP shall be considered separately 
in light of specific technical, economic, and environmental factors and 
in relation to relevant statutory and regulatory requirements.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., the EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed of final rule on small entities. Small entities include 
small businesses, small not-for-profit enterprises, and government 
entities with jurisdiction over populations that are less than 50,000.
    The SIP revision approvals under section 110 and subchapter I, part 
D, of the Act do not create any new requirements, but simply approve 
requirements that the State is already imposing. Therefore, because the 
Federal SIP approval does not impose any new requirements, the EPA 
certifies that this proposed rule would not have a significant impact 
on any small entities affected. Moreover, due to the nature of the 
Federal-State relationship under the Act, preparation of a regulatory 
flexibility analysis would constitute Federal inquiry into the economic 
reasonableness of State actions. The Act forbids the EPA to base its 
actions concerning SIP's on such grounds. Union Electric Co. v. 
U.S.E.P.A., 427 U.S. 246, 256-266 (S. Ct. 1976); 42 U.S.C. section 
7410(a)(2).
    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(Unfunded Mandates Act), signed into law on March 22, 1995, the 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 
the private sector, of $100 million or more. Under section 205, the 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 the EPA to establish a 
plan for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    The EPA has determined that the approval action promulgated today 
does not include a Federal mandate that may result in estimated costs 
of $100 million or more to 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.
    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the procedures published in the 
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a 
July 10, 1995, memorandum from Mary Nichols, Assistant Administrator 
for Air and Radiation. The Office of Management and Budget has exempted 
this regulatory action from Executive Order 12866 review.
    Under section 307(b)(1) of the Act, 42 U.S.C. 7607(b), petitions 
for judicial review of this action must be filed in the United States 
Court of Appeals for the appropriate circuit by August 19, 1996. 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).)
