ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[IA-15-1-7173; FRL-5287-2]
Approval and Promulgation of Implementation Plans; State of Iowa
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This final action approves the State Implementation Plan (SIP)
revision submitted by the state of Iowa. The revision includes special
requirements for nonattainment areas, compliance and enforcement
information, and adoption of EPA definitions. These revisions
strengthen the SIP with respect to attainment and maintenance of
established air quality standards.
effective DATE: This rule is effective on November 29, 1995.
ADDRESSES: Copies of the documents relevant to this action are
available for public inspection during normal business hours at the
Environmental Protection Agency, Air Branch, 726 Minnesota Avenue,
Kansas City, Kansas 66101; and EPA Air & Radiation Docket and
Information Center, 401 M Street SW., Washington, DC 20460.
FOR FURTHER INFORMATION CONTACT: Christopher D. Hess at (913) 551-7213.
SUPPLEMENTARY INFORMATION: On June 23, 1995, the EPA published a direct
final rule (60 FR 32601-3263) for an SIP revision and received one
adverse comment concerning special requirements for nonattainment
areas. Therefore, the EPA is addressing that comment and taking final
action.
Public Comment
As indicated in EPA's direct final notice at 60 FR 32601, the state
has deleted subrule 22.5(2)c. This provision exempted sources in
secondary particulate matter nonattainment areas from offset
requirements if they could show that offsets were not reasonably
available.
In response to this change, a commenter noted that the rule enabled
an applicant to ``demonstrate'' that emission offsets were not
reasonably available. The commenter further stated that deleting this
rule was too restrictive and should not be approved.
Background and Response to Comment
The rule in question concerns the requirement for emission offsets
in nonattainment areas. The Act, as amended in 1990, requires a source
in an area designated nonattainment to achieve offsets so that even
with emission increases from the new source,
[[Page 55199]]
there is reasonable further progress towards attainment in the area.
Iowa's preamended rule was developed for certain particulate matter
nonattainment areas. The purpose was to attain the national ambient air
quality standards for total suspended particulate matter (TSP). Under
the TSP standards (which had a secondary standard in addition to the
primary standard), some areas in Iowa were nonattainment for the
secondary standard, but not for the primary standard. The rule relating
to reasonably available offsets did not apply in primary nonattainment
areas.
After promulgation of the new PM10 standard in 1987 (which
replaced the TSP standard), the distinction between primary and
secondary standards for particulate lost its regulatory significance
since EPA set the same levels for the primary and secondary PM10
standards (see 40 CFR 50.6).
In other words, if Iowa had any particulate matter nonattainment
areas under the new standard, such areas would necessarily be in
violation of both the primary and secondary standard. Therefore, the
provisions of the former 22.5(2)c would not apply. In addition, since
Iowa currently has no designated particulate nonattainment areas, there
are no particulate matter offset requirements in effect.
Iowa has chosen to amend its new source review rules to meet the
requirements of the Act. Iowa is also in the process of making
additional revisions to its rules to meet the requirements of section
110 and part D of title I of the Act to address the primary SO2
nonattainment area in Muscatine. Iowa's decision to eliminate the
``reasonably available'' offset provision is consistent with its
overall effort to meet the requirements of the Act, as amended in 1990.
Therefore, because it is consistent with the Act, and for the
reasons stated in EPA's June 23, 1995, notice, EPA is approving the
Iowa revision.
EPA Action
EPA is taking final action to approve revisions submitted on
October 18, 1994, and January 26, 1995, for the state of Iowa.
Nothing in this action should be construed as permitting, allowing,
or establishing a precedent for any future request for a revision to
any SIP. Each request for a revision to the SIP shall be considered
separately in light of specific technical, economic, and environmental
factors, and in relation to relevant statutory and regulatory
requirements.
SIP 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, EPA 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
Act, preparation of a regulatory flexibility analysis would constitute
Federal inquiry into the economic reasonableness of state action. The
Act forbids EPA to base its actions concerning SIPs on such grounds
(Union Electric Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 (S.Ct. 1976);
42 U.S.C. 7410(a)(2)).
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 E.O. 12866 review.
Unfunded Mandates
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.
Through submission of this SIP, the state has elected to adopt the
program provided for under section 110 of the Clean Air Act. These
rules may bind state and local governments to perform certain actions
and also require the private sector to perform certain duties. To the
extent that the rules being finalized for approval by this action will
impose new requirements, sources are already subject to these
regulations under state law. Accordingly, no additional costs to state
or local governments, or to the private sector, result from this final
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 or local governments in the aggregate or to the private sector.
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 December 29, 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).)
