ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[OK-13-1-7080a, FRL-5822-3]
Approval of a Revision to a State Implementation Plan; Oklahoma;
Revision to Particulate Matter Regulations
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The EPA is approving revisions to the Oklahoma State
Implementation Plan (SIP) submitted by the Governor on May 16, 1994.
This action approves revisions to the Oklahoma SIP by adopting new
rules and opacity requirements to control particulate matter emissions
from new, modified, and existing cotton gin operations. Approval of
this revision will strengthen the SIP by making it Federally
enforceable. In addition, the new rules will simplify the process
weight regulations in the State.
DATES: This action is effective on July 14, 1997, unless critical or
adverse comments are received by June 13, 1997. If the effective date
is delayed, timely notice will be published in the Federal Register.
ADDRESSES: Comments should be mailed to Mr. Thomas Diggs, Chief, Air
Planning Section (6PD-L), EPA Region 6, 1445 Ross Avenue, Suite 700,
Dallas, Texas 75202-2733. Copies of the State's submittal and other
information relevant to this action are available for inspection during
normal business hours at the following locations:

SUPPLEMENTARY INFORMATION:
I. Background
The revisions to this SIP action respond to the requirements of
Section 110 of the Federal Clean Air Act (the Act), as amended in 1990.
Section 110 requires States to adopt and submit to the Administrator a
plan which provides for implementation, maintenance, and enforcement of
the primary and secondary standards for the State. Code of Federal
Regulations (CFR), 40 Part 50.6 defines the level of the National
primary and secondary 24-hour ambient air quality standards (NAAQS) for
particulate matter as 150 micrograms per cubic meter (g/
m3), 24-hour average concentration and 50 g/
m3, annual arithmetic mean. Although Oklahoma is in
attainment of the standards for particulate matter, submission and
approval of this revision serves to strengthen the SIP in Oklahoma by
making it federally enforceable.
This SIP action approves the new cotton gin requirements and
opacity rules developed by the State of Oklahoma in consultation with
EPA and the affected industry. The new rules require cotton gins to
install specific control equipment and to meet a 20 percent visible
emissions limit. The affected sources from this action are located
throughout the State, but predominately in rural areas. Previously,
Oklahoma did not have specific rules for cotton gin operations.
Instead, this category of source was regulated under existing general
particulate matter rules. These rules serve to strengthen the existing
SIP by superseding the general requirements and by making them
federally enforceable. In addition, they are applicable to new,
existing, and modified gins.
During the development of the State rules, Oklahoma referenced
various other State requirements and the EPA Visible Emissions (VE)
performance testing methods in 40 CFR Part 60, Appendix A. The approved
method for determining VE is Reference Method 9 (Method 9 or RM 9).
Method 9 discusses how to make visual determinations of opacity for
emissions from stationary sources. The mechanism for determining VE by
States has often included the use of an opacity regulation to assist in
meeting or maintaining the particulate matter air quality standard.
II. Analysis of State Submittal
Emission Limit
Fugitive emissions from the cotton gin burr hopper dumping area
have been a major source of complaints from inhabited areas. Amendments
to the State rules update the control requirements for cotton gins
throughout Oklahoma by specifying the emissions limitations and
specific control measures to be utilized by new, modified, or existing
cotton gins. To control fugitive emissions from burr hoppers during
dumping, the use of total enclosure at existing gin sites located
within the corporate city limits of any city or within 300 feet of two
or more occupied establishments is required. All new gin sites are
required to install and use a total enclosure on the burr hopper.
Action must also be taken to minimize fugitive dust emissions during
transportation and other operations. An opacity limit of 20 percent is
set for discharges. This opacity limit, however, may be increased for
particulates but only after the owner/operator can demonstrate to the
satisfaction of the Oklahoma Air Quality Council at a public hearing
that their controls meet State requirements and do not violate the
National Ambient Air Quality Standards (NAAQS).
Emission Control Equipment
The Oklahoma cotton gin rule specifies the 1D/3D cyclone as the
approved control equipment on high-pressure exhausts. This gives higher
control efficiencies than the 2D/2D cyclone which is commonly used in
cotton gin operations and has a comparable cost. Some facilities in
Oklahoma have voluntarily installed 1D/3D cyclones prior to the
adoption of this State regulation. However, to minimize the adverse
economic impact, a phased-in approach is taken on existing facilities
allowing continued use of 2D/2D cyclones until repair costs are no
longer cost effective. Facilities will then be required to replace the
older equipment with 1D/3D equipment.
For low-pressure exhausts, the use of 70 mesh or finer screens (or
approved equivalent) is required. This is the most effective of the
sizes considered (70, 80, and 100 mesh). The new rules provide equal or
superior control of emissions compared with that provided for the
cotton gin industry by the existing
[[Page 26394]]
general particulate matter control rules and guidelines.
Recordkeeping
All new, modified, or existing cotton gins are required to comply
with the State rules and are required to maintain a log documenting the
daily process weight, hours of operation, and air emission control
equipment replacement schedule or repair costs.
III. Final Action
These rules have been developed with the cooperation of the
affected industry, and use a control technology basis for determination
of compliance. The rules are needed because the industry represents a
significant source of particulate matter emissions and fugitive dust
previously controlled by general particulate matter control rules and
guidelines.
The EPA is approving the State's SIP revision and the adopted new
rules pertaining to opacity requirements for cotton gin operations in
Oklahoma. The EPA has reviewed the submittal for consistency with the
Act, EPA regulations, and EPA policy. The EPA has determined that the
rules meet the Act's requirements for revision to the SIP and today is
approving under section 110 the above mentioned cotton gin rules.
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 this FR
publication, the EPA is proposing to approve these SIP revisions should
adverse or critical comments be received. This action will be effective
July 14, 1997, unless adverse or critical comments are received by June
13, 1997.
If the EPA receives such comments, this action will be withdrawn
before the effective date by publishing a subsequent action that will
withdraw the final action. All public comments received will be
addressed in a subsequent final 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. If no such adverse comments are received, the
public is advised that this action will be effective on July 14, 1997.
Nothing in this action should be construed as permitting or
allowing or establishing a precedent for any future request for
revision to any SIP. Each request for revision to the SIP shall be
considered separately in light of specific technical, economical, and
environmental factors and in relation to relevant statutory and
regulatory requirements.
IV. Administrative Requirements
A. Executive Order (E.O.) 12866
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 Executive Order 12866 review.
B. Regulatory Flexibility Act
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. See 5 U.S.C. 603 and 604.
Alternatively, the 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 population of less than
50,000.
The 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, I certify 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.
See Union Electric Co. v. U.S. EPA, 427 U.S. 246, 256-66 (1976); 42
U.S.C. 7410(a)(2)).
C. Unfunded Mandates
Under section 202 of the Unfunded Mandates Reform Act of 1995,
signed into law on March 22, 1995, EPA must prepare a budgetary impact
statement to accompany any proposed or final rule that includes a
Federal mandate that may result in estimated costs to State, local, or
tribal governments in the aggregate; or to private sector, of $100
million or more. Under section 205, the EPA must select the most cost-
effective and least burdensome alternative that achieves the objectives
of the rule and is consistent with statutory requirements. Section 203
requires the EPA to establish a plan for informing and advising any
small governments that may be significantly or uniquely impacted by the
rule.
The 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. The Federal action approves
preexisting requirements under State or local law, and imposes no new
Federal requirements. Accordingly, no additional costs to the State,
local, or tribal governments, or to the private sector, result from
this action.
D. Submission to Congress and the General Accounting Office
Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business
Regulatory Enforcement Fairness Act of 1996, the EPA submitted a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives and the Comptroller General of the
General Accounting Office prior to publication of this rule in today's
Federal Register. This rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
E. Petitions for Judicial Review
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 July 14, 1997. 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).
