Approval and Promulgation of Air Quality Implementation Plans;
Delaware; Particulate Matter (PM-10): Group III Areas State
Implementation Plan
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is approving a State implementation plan (SIP) revision
submitted by the State of Delaware. This revision establishes and
requires the implementation of primary and secondary particulate matter
standards consistent with the national ambient air quality standards
(NAAQS) for particulate matter (PM-10). The intended effect of this
action is to approve four (4) regulations, amended by Delaware in order
to conform with the requirements established for Group III areas for
PM-10. This action is being taken under Section 110 of the Clean Air
Act.
EFFECTIVE DATE: This action will become effective June 6, 1994 unless
notice is received by May 6, 1994 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 Thomas J. Maslany, Director, Air,
Radiation, and Toxics Division, U.S. Environmental Protection Agency,
Region III, 841 Chestnut Building, Philadelphia, PA 19107. Copies of
the documents relevant to this action are available for public
inspection during normal business hours at the Air, Radiation, and

SUPPLEMENTARY INFORMATION: On April 26, 1988, the Delaware Department
of Natural Resources and Environmental Control submitted a revision to
the Delaware State implementation plan (SIP) to achieve and maintain
the national ambient air quality standards (NAAQS) for particulate
matter (PM-10). The revision consists of: (1) Regulation 1--
``Definitions and Administrative Principles''; (2) Regulation 3--
``Ambient Air Quality Standards''; (3) Regulation 15--``Air Pollution
Alert and Emergency Plan''; and (4) Regulation 25--``Requirements for
Preconstruction Review''.
The April 26, 1988 submittal also contained revised cutpoints for
the motor vehicle exhaust emissions testing program in Delaware and a
newly-adopted volatile organic compound (VOC) control regulation for
equipment leaks at synthetic organic chemical manufacturing industry
(SOCMI) facilities. The former was addressed under a separate
rulemaking at 55 FR 3402. The latter is also being addressed under a
separate rulemaking. This notice will address only that portion of the
State of Delaware's April 26, 1988 submittal pertaining to PM-10.
The April 26, 1988 submittal is consistent with the SIP revision
requirements for PM-10 Group III areas as detailed in the July 1, 1987
Federal Register notice (52 FR 24672). The amended Delaware regulations
are consistent with the NAAQS for PM-10, and specify:
PM-10 as an indicator of particulate matter.
exceedance levels.
reference methods for measurement of PM-10.
emergency episode plan revisions to include PM-10.
Prevention of Significant Deterioration (PSD) regulation
standards for both PM-10 and Total Suspended Particulate (TSP), with
standards for emission rates and significant monitoring concentrations.
Summary of SIP Revision
On July 1, 1987, EPA promulgated national ambient air quality
standards (NAAQS) for particulate matter with an aerodynamic diameter
less than or equal to a nominal 10 micrometers (PM-10) (52 FR 24634).
The PM-10 standards replace the total suspended particulate (TSP)
standards promulgated by EPA in 1971. Also on July 1, 1987, EPA
promulgated changes to the policies and regulations by which it will
implement the NAAQS for PM-10 in 40 CFR parts 51 and 52 (52 FR 24672).
Using the classification criteria established at 52 FR 24672, EPA
has preliminarily designated areas within each State as Group I, II, or
III based upon an area's probability of attaining the PM-10 standard.
The July 1, 1987 Federal Register notice requires State implementation
plan (SIP) revisions for all classified Group I, II, and III areas and
indicates the SIP revision requirements for each classification.
On August 7, 1987, the State of Delaware was classified at 52 FR
29383 as follows:
Group III--The entire State of Delaware.
The Clean Air Act as amended (1990 Amendments) did not affect the
requirements established for Group III areas. The July 1, 1987 Federal
Register requires States to seek approval of SIP revisions as required
under the preconstruction review program and to codify other minor
regulatory changes as needed. It is presumed that the existing Delaware
SIP is adequate to demonstrate attainment and maintenance of the NAAQS
for PM-10 in all Group III areas in the State. On April 26, 1988, the
State of Delaware responded to the July, 1, 1987 Federal Register by
submitting four (4) regulations amended to reflect the revised
particulate matter standards as a SIP revision. This SIP revision
addresses Group III areas only.
EPA Evaluation
EPA has evaluated Delaware's SIP revision request and concluded the
following: (1) The amended regulations conform with the revised primary
and secondary NAAQS for PM-10; (2) the amended regulations are clearly
enforceable; and (3) the applicable requirements of 40 CFR part 51 have
been met. A more detailed evaluation is provided in the Technical
Support Document available upon request from the Regional EPA office
listed in the ADDRESSES section of this notice.
EPA is approving this SIP revision without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. These revisions to Delaware's regulations have
been effective in the State since March 29, 1988. This action will be
effective June 6, 1994 unless, by May 6, 1994, notice is received that
adverse or critical comments will be submitted. If such notice is
received, this action will be withdrawn before the effective date by
simultaneously publishing two subsequent notices. One notice will
withdraw the final action and another will begin a new rulemaking by
announcing a proposal of the action and establishing a comment period.
If no such comments are received, the public is advised that this
action will be effective on June 6, 1994.
Final Action
EPA is approving the four (4) regulations submitted by the Delaware
Department of Natural Resources and Environmental Control as a revision
to the Delaware SIP. EPA's review of this material indicates that it
conforms to the requirements of 40 CFR parts 51 and 52, and to the July
1, 1987 promulgation of NAAQS for PM-10 in the Federal Register.
The Agency has reviewed this request for revision of the Federally-
approved State implementation plan for conformance with the provisions
of the 1990 Amendments enacted on November 15, 1990. The Agency has
determined that this action conforms with those requirements
irrespective of the fact that the submittal preceded the date of
enactment.
Nothing in this action shall 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 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 Clean Air Act, 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).
This SIP revision establishing revised particulate matter standards
in Delaware has been classified as a Table 3 action for signature by
the Acting 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. On January 6, 1989, the Office of
Management and Budget (OMB) waived Table 2 and Table 3 SIP revisions
from the requirements of section 3 of Executive Order 12291 for a
period of two years. EPA has submitted a request for a permanent waiver
for Table 2 and 3 SIP revisions. OMB has agreed to continue the waiver
until such time as it rules on EPA's request. This request is still
applicable under Executive Order 12866, which superseded Executive
Order 12291 on September 30, 1993.
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 June 6, 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) of the Clean Air
Act.)
