[IA-13-1-6572a; FRL-5210-7]
Approval and Promulgation of Implementation Plans and Section
111(d) Plans; State of Iowa, Polk County
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: This final action approves the State Implementation Plan (SIP)
revision submitted by the state of Iowa on behalf of Polk County, and
approves the addition of an emissions limit for sulfuric acid mist from
sulfuric acid manufacturing to Iowa's section 111(d) plan.
The state's revision involves modifications to the Polk County air
pollution control rules. Polk County is an attainment area for all
criteria pollutants. The Polk County air rules were revised to make
them consistent with the state of Iowa's rules contained in the Iowa
Administrative Code (IAC), which have been previously approved by EPA
as meeting the requirements of the Clean Air Act.
DATES: This final rule is effective August 14, 1995 unless by July 13,
1995 adverse or critical comments are received.
ADDRESSES: Copies of the state submittal and the EPA-prepared technical
support document (TSD) 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
and Radiation Docket and Information Center, 401 M Street, S.W.,
Washington, DC 20460.
FOR FURTHER INFORMATION CONTACT: Christopher D. Hess at (913) 551-7213.
SUPPLEMENTARY INFORMATION: Beginning with its initial submission in
1972, the state of Iowa has operated a Federally approved SIP pursuant
to the requirements of the Clean Air Act (CAA). During the past two
decades, numerous revisions and updates have been made to the SIP in
response to new Federal requirements.
The state of Iowa's section 111(d) plan for the control of sulfuric
acid mist emissions from existing sulfuric acid production plants and
for the control of fluoride emissions from existing phosphate
fertilizer plants was approved by EPA in a Federal Register notice,
under the Code of Federal Regulations Part 62 (50 FR 52920), published
December 27, 1985.
REVIEW OF STATE SUBMITTAL: On May 5, 1994, the state of Iowa submitted
to EPA Polk County Ordinance No. 132, which [[Page 31091]] modifies the
Polk County Board of Health regulation Chapter 5, Air Pollution. Polk
County Ordinance No. 132, which was adopted by the Polk County Board of
Supervisors on October 26, 1993, and became effective December 2, 1993,
made a number of revisions to the Polk County air pollution control
regulations. The state has provided evidence of control regulations.
The state has provided evidence of the lawful adoption of regulations,
public notice, and public hearing requirements.
The state has requested that these revisions be approved as a
modification of the SIP, with the exception of the following articles
and sections: Chapter V, Article VI, Section 5-16 (n) and (p) (Specific
Emissions Standards); Chapter V, Article VIII (Emission of Odors;
Slaughterhouses; Reduction of Animal Matter); and Chapter V, Article
XIII (Variances). The revisions include air pollution control
definitions that parallel those in the IAC and in various Federal
requirements for state programs; for example, definitions relating to
new source permitting.
Other revisions that were made in the Polk County air pollution
control regulations include the following items.
1. Visible Emission Measurement. In Chapter V, Articles III and IV,
Sections 5-6, 5-8, and 5-9, references to the Ringelmann Chart as a
measure of visible emissions were deleted, leaving opacity as the
standard by which visible emissions are measured. The opacity standard
by which visible emissions are measured has not been modified from that
in the approved SIP. The deletion of the Ringelmann Chart as a measure
of visible emissions makes the requirements consistent with the EPA-
approved, state rules, in chapter 23, sections 3(d) and 4(12).
2. Stack Testing. In Chapter V, Article VII, Section 5-18, the
conditions that must be satisfied when stack emission tests are
required were revised to include earlier notification of stack testing
by equipment owners. The revisions make the requirements consistent
with the state rule in chapter 25, section 1(7).
3. Fuel-Burning Permit Exemptions. In Chapter V, Article X,
Sections 5-33 and 5-39, the capacity of fuel-burning equipment that is
exempt from needing a permit was reduced from equipment with a capacity
of less than 50 million Btu per hour input (in the previously approved
SIP) to equipment with a capacity of less than 10 million Btu per hour
input.
Additionally, the exemption from needing a permit for fuel-burning
equipment for indirect heating with a capacity less than one million
Btu per hour input when burning No. 1 or No. 2 fuel, exclusively, was
deleted. These revisions expand the coverage of emission-control
requirements for fuel-burning sources. In addition, the revisions make
these local requirements consistent with the state rule in chapter 22,
section 1(2).
4. Sulfuric Acid Emissions Limits. Polk County Ordinance No. 132
also sets emissions limits for sulfuric acid mist from sulfuric acid
manufacturing. The sulfuric acid mist emissions limit, as set in the
ordinance, is 0.5 pounds of sulfuric acid mist per ton of acid
produced. This is identical to the limit contained in EPA's ``Final
Guideline Document: Control of Sulfuric Acid Mist Emissions from
Existing Sulfuric Acid Production Units'' (EPA-450/2-77-019).
For additional information on revisions made in the Polk County air
pollution control regulations, the reader may refer to EPA's TSD
prepared for this Iowa SIP revision.
EPA Action: EPA is taking final action to approve the revisions to
the SIP and 111(d) plan submitted on May 5, 1994, for the state of
Iowa, Polk County. As discussed previously, this does not include the
rules contained in Chapter V, Article VI, Section 5-16(n) and (p);
Chapter V, Article VIII; and Chapter V, Article XIII.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any SIP or 111(d) plan. Each request for a revision to the
SIP or 111(d) 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
CAA, and 111(d) plan approvals under section 111 of the CAA do not
create any new requirements, but simply approve requirements that the
state is already imposing. Therefore, because the Federal SIP approval
and 111(d) plan approval do not impose any new requirements, EPA
certifies that they do 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 regulatory flexibility analysis would
constitute Federal inquiry into the economic reasonableness of state
action. The CAA 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)).
The Office of Management and Budget has exempted these actions from
review under Executive Order 12866.
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by August 14, 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)).
The EPA is publishing this action without prior proposal because
the Agency views this as a noncontroversial amendment and anticipates
no adverse comments. However, in a separate document in the Federal
Register publication, the EPA is proposing to approve the SIP revisions
and 111(d) plan revision should adverse or critical comments be filed.
If the EPA receives such comments, this action will be withdrawn
before the effective date by publishing a subsequent notice that will
withdraw the final action. All public comments received will then be
addressed in a subsequent rule based on this action serving as a
proposed rule. The 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.
