40 CFR Part 52

[SIPTRAX No. PA63-1-7032a; FRL-5211-1]


Approval and Promulgation of Air Quality Implementation Plans; 
Commonwealth of Pennsylvania: Determination of Attainment of Ozone 
Standard by the Pittsburgh-Beaver Valley and Reading Ozone 
Nonattainment Areas and Determination Regarding Applicability of 
Certain Reasonable Further Progress and Attainment Demonstration 
Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA has determined that the Pittsburgh-Beaver Valley and 
Reading ozone nonattainment areas have attained the National Ambient 
Air Quality Standard (NAAQS) for ozone. This determination is based 
upon three years of ambient air monitoring data for the years 1992-94 
that demonstrate that the ozone NAAQS has been attained in these areas. 
On the basis of this determination, EPA is also determining that 
certain reasonable further progress and attainment demonstration 
requirements, along with certain other related requirements, of Part D 
of Title I of the Clean Air Act (CAA) are not applicable to these areas 
as long as these areas continue to attain the ozone NAAQS.

EFFECTIVE DATE: This action will become effective July 10, 1995 unless 
notice is received on or before June 26, 1995 that adverse or critical 
comments will be submitted. If the effective date is delayed, timely 
notice will be published in the Federal Register.

ADDRESSES: Comments may be mailed to Marcia L. Spink, Associate 
Director, Air Programs, Mailcode 3AT00, U.S. Environmental Protection 
Agency, Region III, 841 Chestnut Building, Philadelphia, Pennsylvania 
19107. Copies of the documents relevant to this action are available 
for public inspection during normal business hours at the Air, 
Radiation, and Toxics Division, U.S. Environmental Protection Agency, 
Region III, 841 Chestnut Building, Philadelphia, Pennsylvania 19107.

SUPPLEMENTARY INFORMATION:

I. Background

    Subpart 2 of Part D of Title I of the Clean Air Act (CAA) contains 
various air quality planning and state implementation plan (SIP) 
submission requirements for ozone nonattainment areas. EPA believes it 
is reasonable to interpret provisions regarding reasonable further 
progress (RFP) and attainment demonstrations, along with certain other 
related provisions, so as not to require SIP submissions if an ozone 
nonattainment area subject to those requirements is monitoring 
attainment of the ozone standard (i.e., attainment of the NAAQS 
demonstrated with three consecutive years of complete, quality assured 
air quality monitoring data). As described below, EPA has previously 
interpreted the general provisions of subpart 1 of part D of Title I 
(sections 171 and 172) so as not to require the submission of SIP 
revisions concerning RFP, attainment demonstrations, or contingency 
measures. As explained in a memorandum dated May 10, 1995, from John S. 
Seitz, Director, Office of Air Quality Planning and Standards to the 
Regional Air Division Directors, entitled ``Reasonable Further 
Progress, Attainment Demonstration, and Related Requirements for Ozone 
Nonattainment Areas Meeting the Ozone National Ambient Air Quality 
Standard'', EPA believes it is appropriate to interpret the more 
specific RFP, attainment demonstration and related provisions of 
subpart 2 in the same manner.
    First, with respect to RFP, section 171(1) states that, for 
purposes of part D of Title I, RFP ``means such annual incremental 
reductions in emissions of the relevant air pollutant as are required 
by this part or may reasonably be required by the Administrator for the 
purpose of ensuring attainment of the applicable national ambient air 
quality standard by the applicable date.'' Thus, whether dealing with 
the general RFP requirement of section 172(c)(2), or the more specific 
RFP requirements of subpart 2 for classified ozone nonattainment areas 
(such as the 15 percent plan requirement of section 182(b)(1)), the 
stated purpose of RFP is to ensure attainment by the applicable 
attainment date.\1\ If an area has in fact attained the standard, the 
stated purpose of the RFP requirement will have already been fulfilled 
and EPA does not believe that the area need submit revisions providing 
for the [[Page 27894]] further emission reductions described in the RFP 
provisions of section 182(b)(1).

    \1\EPA notes that paragraph (1) of subsection 182(b) is entitled 
``PLAN PROVISIONS FOR REASONABLE FURTHER PROGRESS'' and that 
subparagraph (B) of paragraph 182(c)(2) is entitled ``REASONABLE 
FURTHER PROGRESS DEMONSTRATION,'' thereby making it clear that both 
the 15 percent plan requirement of section 182(b)(1) and the 3 
percent per year requirement of section 182(c)(2) are specific 
varieties of RFP requirements.
    EPA notes that it took this view with respect to the general RFP 
requirement of section 172(c)(2) in the General Preamble for the 
Interpretation of Title I of the Clean Air Act Amendments of 1990 (57 
FR 13498 (April 16, 1992)), and it is now extending that interpretation 
to the specific provisions of subpart 2. In the General Preamble, EPA 
stated, in the context of a discussion of the requirements applicable 
to the evaluation of requests to redesignate nonattainment areas to 
attainment, that the ``requirements for RFP will not apply in 
evaluating a request for redesignation to attainment since, at a 
minimum, the air quality data for the area must show that the area has 
already attained. Showing that the State will make RFP towards 
attainment will, therefore, have no meaning at that point.'' (57 FR 
13564)<SUP>2

    \2\See also ``Procedures for Processing Requests to Redesignate 
Areas to Attainment,'' from John Calcagni, Director, Air Quality 
Management Division, to Regional Air Division Directors, September 
4, 1992, at page 6 (stating that the ``requirements for reasonable 
further progress * * * will not apply for redesignations because 
they only have meaning for areas not attaining the standard'') 
(hereinafter referred to as ``September 1992 Calcagni memorandum'').
---------------------------------------------------------------------------

    Second, with respect to the attainment demonstration requirements 
of section 182(b)(1), an analogous rationale leads to the same result. 
Section 182(b)(1) requires that the plan provide for ``such specific 
annual reductions in emissions * * * as necessary to attain the 
national primary ambient air quality standard by the attainment date 
applicable under this Act.'' As with the RFP requirements, if an area 
has in fact monitored attainment of the standard, EPA believes there is 
no need for an area to make a further submission containing additional 
measures to achieve attainment. This is also consistent with the 
interpretation of certain section 172(c) requirements provided by EPA 
in the General Preamble to Title I, as EPA stated there that no other 
measures to provide for attainment would be needed by areas seeking 
redesignation to attainment since ``attainment will have been 
reached.'' (57 FR 13564; see also September 1992 Calcagni memorandum at 
page 6.) Upon attainment of the NAAQS, the focus of state planning 
efforts shifts to maintenance of the NAAQS and the development of a 
maintenance plan under section 175A.
    Similar reasoning applies to the contingency measure requirements 
of section 172(c)(9). EPA has previously interpreted the contingency 
measure requirement of section 172(c)(9) as no longer being applicable 
once an area has attained the standard since those ``contingency 
measures are directed at ensuring RFP and attainment by the applicable 
date.'' (57 FR 13564; see also September 1992 Calcagni memorandum at 
page 6.) Similarly, as the section 172(c)(9) contingency measures are 
linked with the RFP requirements of section 182(b)(1), the requirement 
no longer applies once an area has attained the standard.
    EPA emphasizes that the lack of a requirement to submit the SIP 
revisions discussed above exists only for as long as an area designated 
nonattainment continues to attain the standard. If EPA subsequently 
determines that such an area has violated the NAAQS, the basis for the 
determination that the area need not make the pertinent SIP revisions 
would no longer exist. The EPA would notify the State of that 
determination and would also provide notice to the public in the 
Federal Register. Such a determination would mean that the area would 
have to address the pertinent SIP requirements within a reasonable 
amount of time, which EPA would establish taking into account the 
individual circumstances surrounding the particular SIP submissions at 
issue. Thus, a determination that an area need not submit one of the 
SIP submittals amounts to no more than a suspension of the requirement 
for so long as the area continues to attain the standard.
    The State must continue to operate an appropriate air quality 
monitoring network, in accordance with 40 CFR part 58, to verify the 
attainment status of the area. The air quality data relied upon to 
determine that the area is attaining the ozone standard must be 
consistent with 40 CFR part 58 requirements and other relevant EPA 
guidance and recorded in EPA's Aerometric Information Retrieval System 
(AIRS).
    The determinations that are being made with this Federal Register 
notice are not equivalent to the redesignation of the area to 
attainment. Attainment of the ozone NAAQS is only one of the criteria 
set forth in section 107(d)(3)(E) that must be satisfied for an area to 
be redesignated to attainment. To be redesignated the state must submit 
and receive full approval of a redesignation request for the area that 
satisfies all of the criteria of that section, including the 
requirement of a demonstration that the improvement in the area's air 
quality is due to permanent and enforceable reductions and the 
requirements that the area have a fully-approved SIP meeting all of the 
applicable requirements under section 110 and Part D and a fully-
approved maintenance plan.
    Furthermore, the determinations made in this notice do not shield 
an area from future EPA action to require emissions reductions from 
sources in the area where there is evidence, such as photochemical grid 
modeling, showing that emissions from sources in the area contribute 
significantly to nonattainment in, or interfere with maintenance by, 
other nonattainment areas. EPA has authority under sections 
110(a)(2)(A) and 110(a)(2)(D) to require such emission reductions as 
necessary and appropriate to deal with transport situations.

II. Analysis of Air Quality Data

    EPA has reviewed the ambient air monitoring data for ozone 
(consistent with the requirements contained in 40 CFR part 58 and 
recorded in AIRS) for the Pittsburgh-Beaver Valley and Reading moderate 
ozone nonattainment areas in the Commonwealth of Pennsylvania from 1992 
through the present time. On the basis of that review EPA has concluded 
that the area attained the ozone standard during the 1992-94 period and 
continues to attain the standard at this time.
    The current design value for the Pittsburgh-Beaver Valley 
nonattainment area, computed using ozone monitoring data for 1992 
through 1994, is 121 parts per billion (ppb). The average annual number 
of expected exceedances is 0.7 for that same time period. The current 
design value for the Reading nonattainment area, computed using ozone 
monitoring data for 1992 through 1994, is 105 ppb. The average annual 
number of expected exceedances is 0.3 for that same time period. An 
area is considered in attainment of the standard if the average annual 
number of expected exceedances is less than or equal to 1.0. Thus, 
these areas are no longer recording violations of the air quality 
standard for ozone. A more detailed summary of the ozone monitoring 
data for the area is provided in the Technical Support Document for 
this notice.
    EPA is making these determinations without prior proposal. However, 
in a separate document in this Federal Register publication, EPA is 
proposing to make these determinations should adverse or critical 
comments be filed. This action will be effective July 10, 1995 unless, 
within 30 days of publication, adverse or critical comments are 
received.
    If EPA receives such comments, this action will be withdrawn before 
the effective date by publishing a subsequent notice that will withdraw 
[[Page 27895]] 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. 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 received, the public is 
advised that this action will be effective on July 10, 1995.

Final Action

    EPA has determined that the Pittsburgh-Beaver Valley and Reading 
ozone nonattainment areas have attained the ozone standard and continue 
to attain the standard at this time. As a consequence of this 
determination, the requirements of section 182(b)(1) concerning the 
submission of the 15 percent plan and ozone attainment demonstration 
and the requirements of section 172(c)(9) concerning contingency 
measures are not applicable to the area so long as the area does not 
violate the ozone standard. Since these areas will not be required to 
submit 15 percent plans or attainment demonstrations, these areas will 
not be in the control strategy period for conformity purposes for so 
long as the areas do not violate the standard. However, the Pittsburgh-
Beaver Valley and Reading areas, which are already demonstrating 
conformity to a submitted maintenance plan pursuant to 40 CFR Part 51, 
section 51.448(i), may continue to do so, or the Commonwealth may elect 
to withdraw the applicability of the submitted maintenance plan budget 
for conformity purposes until the maintenance plan is approved. The 
applicability may be withdrawn through the submission of a letter from 
the Governor or his or her designee. If the applicability of the 
submitted maintenance plan budget is withdrawn for transportation 
conformity purposes, the build/no-build and less-than-1990 tests will 
apply until the maintenance plan is approved.
    EPA emphasizes that these determinations are contingent upon the 
continued monitoring and continued attainment and maintenance of the 
ozone NAAQS in the affected area. When and if a violation of the ozone 
NAAQS is monitored in the Pittsburgh-Beaver Valley or Reading 
nonattainment areas (consistent with the requirements contained in 40 
CFR part 58 and recorded in AIRS), EPA will provide notice to the 
public in the Federal Register. Such a violation would mean that the 
area would thereafter have to address the requirements of section 
182(b)(1) and section 172(c)(9) since the basis for the determination 
that they do not apply would no longer exist.
    As a consequence of the determination that these areas have 
attained the NAAQS and that the RFP and attainment demonstration 
requirements of section 182(b)(1) do not presently apply, the sanctions 
clocks started by EPA on January 18, 1994, for failure to submit these 
requirements is hereby stopped since the deficiency for which the clock 
was started no longer exists.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any state implementation plan. Each request for revision to 
the state implementation plan 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., 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 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. Today's determination does not create any new requirements, but 
suspends the indicated requirements. Therefore, because this notice 
does not impose any new requirements, I certify that it does not have a 
significant impact on any small entities affected.
    Under Sections 202, 203, and 205 of the Unfunded Mandates Reform 
Act of 1995 (``Unfunded Mandates Act''), signed into law on March 22, 
1995, EPA must undertake various actions in association with proposed 
or final rules that include a Federal mandate that may result in 
estimated costs of $100 million or more to the private sector, or to 
State, local, or tribal governments in the aggregate.
    EPA's final action does not impose any federal intergovernmental 
mandate, as defined in section 101 of the Unfunded Mandates Act, upon 
the State. No additional costs to State, local, or tribal governments, 
or to the private sector, result from this action, which suspends the 
indicated requirements. Thus, EPA has determined that this final action 
does not include a 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 action has been classified as a Table 2 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 
an October 4, 1993 memorandum from Michael H. Shapiro, Acting Assistant 
Administrator for Air and Radiation. The OMB has exempted this 
regulatory action from E.O. 12866 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 July 25, 1995. 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)).
