SUPPLEMENTARY INFORMATION:

I. Summary of State Submittal

    On November 15, 1993, the Wisconsin Department of Natural Resources 
(WDNR) submitted to the USEPA 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 the 
overall ambient air quality monitoring network.
    Section 182(c)(1) of the Act and the General Preamble (57 FR 13515) 
require that USEPA 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.
    The final PAMS rule was promulgated by USEPA on February 12, 1993 
(58 FR 8452). Section 58.40(a) of the revised rule requires the State 
to submit a photochemical assessment monitoring network description, 
including a schedule for implementation, to the Administrator within 6 
months after promulgation or by August 12, 1993. Further, Sec. 58.20(f) 
requires the State to provide for the establishment and maintenance of 
a PAMS network within 9 months after promulgation of the final rule or 
November 12, 1993.
    On August 12, 1993, the Lake Michigan Air Directors Consortium 
(LADCO) submitted an alternative PAMS network description on behalf of 
the LADCO States of Wisconsin, Illinois, and Indiana, including a 
schedule for implementation. This submittal is currently being reviewed 
by the USEPA and is intended to satisfy the requirements of 
Sec. 58.40(a). A joint network description and implementation schedule 
is allowed by Sec. 58.40(a)(3) for States where the State's PAMS 
network requires monitoring stations in different States and/or 
Regions. Since network descriptions may change annually, they are not 
part of the SIP as recommended by the Guideline for the Implementation 
of the Ambient Air Monitoring Regulations 40 CFR 58. However, the 
network description is negotiated and approved during an annual review 
as required by 40 CFR 58.25 and 58.36 and the revision to be codified 
at Sec. 58.46.
    On November 15, 1993, Wisconsin submitted to the USEPA a proposed 
revision to the Wisconsin ozone SIP. This submittal included a copy of 
rule 144.31(1)(g) of the Wisconsin Administrative Rule, ``Air pollution 
control; powers and duties,'' and supplementary information 
demonstrating that the WDNR has the authority to conduct ambient air 
quality monitoring and other activities to determine the magnitude of 
air pollution throughout the State. This would encompass establishing 
and maintaining a PAMS network. A letter finding the submittal complete 
was sent to the State on January 4, 1994.
    The Wisconsin PAMS SIP revision is intended to meet the 
requirements of section 182(c)(1) of the Act and affect compliance with 
the PAMS regulations, to be codified at 40 CFR part 58, as promulgated 
on February 12, 1993.
    The WDNR held a public hearing on the PAMS on November 11, 1993.

II. Analysis of State Submittal

    The Wisconsin PAMS SIP revision will provide Wisconsin with the 
authority to establish and operate the PAMS sites, secure State funds 
for PAMS and provide the USEPA with 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, to be codified at 40 CFR part 58, the 
Guideline for the Implementation of the Ambient Air Monitoring 
Regulations 40 CFR Part 58 (USEPA-450/4-78-038, OAQPS, November 1979), 
the September 2, 1993 memorandum from G. T. Helms entitled Final 
Boilerplate Language for the PAMS SIP Submittal, the Act and the 
General Preamble.
    The September 2, 1993 memorandum from G. T. Helms entitled Final 
Boilerplate Language for the PAMS SIP Submittal stipulates that the 
PAMS SIP, at a minimum, must: enable the monitoring of criteria 
pollutants, such as ozone and NO2 and non-criteria pollutants, 
such as NOx, NO, speciated VOC, including carbonyls, as well as 
meteorological parameters; provide a copy of the approved (or proposed) 
PAMS network description, including the phase-in schedule, for public 
inspection during the public notice and/or comment period provided for 
in the SIP revision or, alternatively, provide information to the 
public upon request concerning the State's plans for implementing the 
rules; make reference to the fact that PAMS will become a part of the 
State or local air monitoring stations (SLAMS) network; and provide a 
statement that SLAMS will employ Federal reference (FRM) or equivalent 
methods while most PAMS sampling will be conducted using methods 
approved by the USEPA which are not FRM or equivalent.
    The Wisconsin SIP revision provides that the network will measure 
ambient levels of ozone, NOx, speciated VOC, including 
hydrocarbons and carbonyls and meteorological data. During the public 
comment period and hearing, Wisconsin provided a copy of the proposed 
alternative PAMS network description, including a schedule of 
implementation, to the public upon request to Ralph Patterson of the 
WDNR. The SIP revision provides that each station in the air quality 
surveillance network provided for by this SIP will be termed a SLAMS. 
Finally, the SIP revision provides that the methods used in SLAMS will 
be reference or equivalent methods as defined by USEPA at 40 CFR 50.1, 
while the methods used in PAMS will be approved by USEPA on a regional 
basis as part of its approval of the network descriptions.

III. Rulemaking Action

    USEPA approves the revision to the Wisconsin ozone SIP for PAMS.
    Because USEPA considers today's action noncontroversial and 
routine, we are approving it today without prior proposal. The action 
will become effective on May 17, 1994. However, if we receive notice by 
April 18, 1994, that someone wishes to submit adverse comments, then 
USEPA will publish: (1) A document that withdraws the action, and (2) a 
document that begins a new rulemaking by proposing the action and 
establishing a comment period.
    Nothing in this action should be construed as permitting, allowing 
or establishing a precedent for any future request for revision to any 
SIP. The USEPA shall consider each request for revision to the SIP in 
light of specific technical, economic, and environmental factors and in 
relation to relevant statutory and regulatory requirements.
    This action has been classified as a Table 3 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225). A revision to the SIP processing 
review tables was approved by the Acting Assistant Administrator for 
Office of Air and Radiation on October 4, 1993 (Michael Shapiro's 
memorandum to Regional Administrators). A future notice will inform the 
general public of these tables. Under the revised tables this action 
remains classified as a Table 2. On January 6, 1989, the Office of 
Management and Budget (OMB) waived Table 2 and 3 SIP revisions from the 
requirements of section 3 of Executive Order 12291 for a period of 2 
years (54 FR 2222). The USEPA has submitted a request for a permanent 
waiver for Table 2 and 3 SIP revisions. The OMB has agreed to continue 
the waiver until such time as it rules on USEPA's request. This request 
continued in effect under Executive Order 12866 which superseded 
Executive order 12291 on September 30, 1993.
    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., USEPA 
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, USEPA may certify that the rule will not have a 
significant 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.
    Because the USEPA's approval of this program does not impose any 
new regulatory requirements on small businesses, I certify that it does 
not have a significant economic impact on any small entities affected.
    Under section 307(b)(1) of the Act, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by May 17, 1994. 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).
    The Agency has reviewed this request for revision of the federally 
approved State Implementation Plan for conformance with the provisions 
of the Act enacted on November 15, 1990.
