SUPPLEMENTARY INFORMATION: On April 26, 1995, the Commonwealth of
Pennsylvania submitted a revision to its State implementation plan
(SIP) for Allegheny County pertaining to the USX Corporation's Clairton
Works. The intended result of the revision is to minimize air pollution
control equipment unavailability. This action will significantly reduce
the potential for excessive sulfur dioxide (SO2) emissions from
the facility.
Background
On January 30, 1991, EPA notified Pennsylvania of EPA's intention
to start the process of redesignating the ``Clairton Area'' in
Allegheny County as nonattainment for SO2 pursuant to section
107(d)(3) of the Clean Air Act. The Clairton Area is defined as the
area inclusive of Lincoln, Liberty, Glassport and Port Vue Boroughs and
the City of Clairton in Allegheny County, Pennsylvania. In response to
EPA's letter, the Commonwealth of Pennsylvania requested on March 3,
1991 that the Clairton Area be redesignated as nonattainment. As a
result, the Clairton Area was proposed to be redesignated as
nonattainment for SO2 on September 22, 1992 (57 FR 43846).
The basis of EPA's determination to redesignate the Clairton Area
as nonattainment for SO2 was the recording of monitored violations
of the 24-hour national ambient air quality standard (NAAQS) for
SO2 in 1986 and 1988 and of the 3-hour NAAQS in 1985, 1986, and
1988. The SO2 monitor that recorded these violations is located in
the Borough of Glassport.
Upon investigation into the cause of the monitored violations, it
was determined that the exceedances were primarily attributable to the
USX Corporation's Clairton Works coking facility located in the City of
Clairton. After discussions with the Allegheny County Health Department
Bureau of Environmental Quality Division of Air Quality and USX, each
of the monitored exceedances correlated with specific sulfur-removal
equipment failures and outages at the Clairton Works. Further, USX
detailed the significant pollution abatement equipment modification and
enhancement program it was implementing at the time to address the
equipment failures and outages. USX was adding redundant pollution
control devices at its coke oven gas desulfurization facility to
greatly reduce SO2 emissions from the facility. Since the
improvement program was initiated, there was a documented reduction in
monitored SO2 concentrations and no monitored exceedances of the
NAAQS recorded since 1990.
Based on this information, EPA deferred the redesignation of this
area to nonattainment on December 21, 1993 (58 FR 67334). The deferral
was contingent upon the codification of the pollution equipment
improvements at the USX Clairton Works into the Pennsylvania State
implementation plan (SIP) revision for Allegheny County. On April 26,
1995, Pennsylvania submitted a request that EPA approve an official
State implementation plan (SIP) revision request for Allegheny County
pertaining to the USX Clairton Works.
Summary of SIP Revision
The April 26, 1995 SIP revision consists of an enforcement order
and agreement (EOA) entered into between the Allegheny County Health
Department and USX Corporation. EPA is specifically approving the
introductory portion of the EOA, the section entitled ``I. Order'' in
its entirety, and two attachments to the EOA. The remainder of the EOA
pertains to certain enforcement provisions agreed to between Allegheny
County and USX. These provisions are not relevant to the SIP revision.
The EOA, entered into between the County and USX on November 17,
1994, establishes general operating procedures at the Clairton Works
regarding certain air pollution control devices. Specifically, the EOA
requires USX to maintain and operate the following control devices: two
Claus Plants at the Clairton Works coke oven gas desulfurization
facility; a hydrogen cyanide (HCN) destruct unit with two catalytic
reactors; a vacuum carbonate unit with two absorber columns, two axi
compressors, and two strippers; and, spare heat exchangers. The goal of
the EOA is to require redundancy of control devices in order to
minimize unavailability of such devices during normal plant operations.
The result of the EOA will be minimized equipment outages and
breakdowns. This action will foster the continued maintenance of the
NAAQS for SO2 in the area surrounding the facility. Because the
area of concern has been monitoring attainment for a number of years
and the previously monitored violations were directly attributable to
pollution control equipment malfunctions and breakdowns, the existing
federally-approved SO2 emission limit for the Clairton Works
continues to be adequate.
Evaluation of State Submittal
In order to evaluate the approvability as a SIP revision of
Pennsylvania's April 26, 1995 submittal, the critical factors to be
considered are (A) whether the revised implementation plan demonstrates
attainment and maintenance of the national ambient air quality
standards (NAAQS) and (B) whether issues of enforceability arise. The
following is an discussion of each of these factors; a more detailed
evaluation is provided in a Technical Support Document available upon
request from the Regional EPA office listed in the ADDRESSES section of
this notice.
A. Impacts on Attainment/Maintenance on the NAAQS
As mentioned earlier, the Clairton Area is currently designated as
attainment for SO2. The EOA promotes continued maintenance of the
NAAQS for SO2 in the area of concern. Since USX began its
pollution control device modification and enhancement program at the
Clairton Works in the early 1990's, the ambient air quality monitors in
the Clairton Area have indicated a
[[Page 43014]]
significant improvement in air quality with regards to SO2. For
the last four years, the three monitoring stations most impacted by the
Clairton Works have recorded maximum annual arithmetic means that are
less than 60 percent of the annual NAAQS (80 g/m3) and
maximum 24-hour averages that are 75 percent of the 24-hour standard
(365 g/m\3\). This provides a strong indication that the
improvements at Clairton Works has had a direct benefit on ambient air
quality in terms of SO2 and that the NAAQS for SO2 should
continue to be maintained.
B. Enforceability Issues
The EOA requires USX to properly maintain and operate a number of
pollution control devices to ensure maximum availability of those
devices during plant operation. The EOA fully articulates the
expectations of USX in terms of the type of equipment that is to be
maintained, the capacity of that equipment, and the required
availability of the equipment. The EOA also indicates the level of
diligence that is to be applied to the operation and maintenance of the
control devices. The EOA requires USX to report any event that causes
the breakdown or unavailability of any of the equipment specified in
the EOA.
EPA is approving this SIP revision without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. However, in a separate document in this Federal
Register publication, EPA is proposing to approve the SIP revision
should adverse or critical comments be filed. This action will be
effective October 17, 1995 unless, by September 18, 1995, adverse or
critical comments are received.
If 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. 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 October 17, 1995.
Final Action
EPA is approving the Pennsylvania SIP revision for the USX Clairton
Works in Allegheny County.
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.
SIP approvals under section 110 and subchapter I, part D of the
Clean Air 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
Administrator certifies that it does not have a significant impact on
any small entities affected. Moreover, due to the nature of the
Federal-State relationship under the CAA, preparation of a flexibility
analysis would constitute Federal inquiry into the economic
reasonableness of State action. The Clean Air Act forbids EPA to base
its actions concerning SIP's on such grounds. Union Electric Co. v.
U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
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 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, EPA 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 approval 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.
Through submission of this State implementation plan or plan
revision, the State and any affected local or tribal governments have
elected to adopt the program provided for under section 110 of the
Clean Air Act. These rules may bind State, local and tribal governments
to perform certain actions and also require the private sector to
perform certain duties. To the extent that the rules being approved by
this action will impose no new requirements; such sources are already
subject to these regulations under State law. Accordingly, no
additional costs to State, local, or tribal governments, or to the
private sector, result from this action. EPA has also determined that
this final action does not include a 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 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
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 October 17, 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 to approve a revision to Pennsylvania's SIP
for Allegheny County pertaining to the USX Clairton Works may not be
challenged later in proceedings to enforce its requirements. (See
section 307(b)(2).)
