ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[OK-8-1-5772a; FRL-6457-7]


Approval and Promulgation of Implementation Plans; Oklahoma; 
Recodification of Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The EPA is taking direct final action approving into the 
Oklahoma State Implementation Plan (SIP), subchapters of the Oklahoma 
Department of Environmental Quality (ODEQ) Air Pollution Control Rules 
adopted by the State Legislature on March 30, 1994. These Rules, 
submitted by the Governor to EPA on May 16, 1994, replace most of the 
existing ODEQ regulations in the Oklahoma SIP. The EPA is taking no 
action on subchapters of the submittal that are either not equivalent 
to, or are not in, the current Oklahoma SIP-approved regulations. 
Approval of this action will make the numbering format and 
administrative terms of the subchapters being approved consistent with 
that of the current ODEQ air quality control regulations. The changes 
are administrative in nature and do not substantively revise the 
current SIP.

DATES: This rule is effective on January 3, 2000 without further 
notice, unless EPA receives adverse comment by December 3, 1999. If EPA 
receive such comment, EPA will publish a timely withdrawal in the 
Federal Register informing the public that this rule will not take 
effect.

ADDRESSES: Written comments on this action should be addressed to Mr. 
Thomas H. Diggs, Chief, Air Planning Section (6PD-L), at the EPA Region 
6 Office listed below. Copies of documents relevant to this action are 
available for public inspection during normal business hours at the

SUPPLEMENTARY INFORMATION: Throughout this document whenever ``we'' is 
used, we mean EPA.

I. What Is the Purpose of This Action?

    This action approves a recodification of the ODEQ regulations in 
the Oklahoma SIP adopted by the Oklahoma Legislature on March 30, 1994, 
and submitted by the Governor of Oklahoma on May 16, 1994, as a 
revision to the Oklahoma SIP. The EPA is approving subchapters of the 
submittal that are equivalent to the current SIP-approved regulations 
replaced. The EPA is taking no action on subchapters that have not 
previously been approved into the Oklahoma SIP or are not equivalent to 
the existing SIP-approved regulations.

II. Why Is EPA Taking This Action?

    The ODEQ has used four different numbering systems for its air 
quality control regulations since the original Oklahoma SIP was 
approved by EPA on May 31, 1972 (37 FR 10887). Regulations in the 
current Oklahoma SIP have been approved under three of these numbering 
systems.
    The ODEQ air quality control regulations approved with the original 
Oklahoma SIP were numbered with a one or two digit number such as 
Regulation Number 4 and Regulation Number 15. Regulations approved by 
EPA under this numbering system were approved in 40 CFR part 52, 
Secs. 52.1920(b) to 52.1920(c)(21). Some ODEQ regulations approved 
under this system are still in the Oklahoma SIP.
    Between 1981 and 1991, the ODEQ used a numbering system such as 
Regulation 1.1, Regulation 1.4.4, and Regulation 4.1 for its air 
quality control regulations. Regulations were approved by EPA under 
this numbering system at 40 CFR 52.1920(c)(24) to 52.1920(c)(41) and 
52.1920(c)(47).
    In 1990 the Oklahoma State Legislature passed the Oklahoma 
Administrative Procedures Act which mandated a common format for all 
Oklahoma rules and regulations. To meet the requirements of the 
Administrative Procedures Act, the Air Quality Service of the Oklahoma 
State Department of Health recodified the Oklahoma air pollution 
control regulations into the Oklahoma Administrative Code, Title 310, 
Chapter 200 (OAC:310:200), Oklahoma Air Pollution Control Rules. As 
required by the Oklahoma Administrative Procedures Act, the Oklahoma 
Air Pollution Control Rules contained no substantive changes, but was a 
change in format only. The Governor of Oklahoma submitted the 
recodified regulations to EPA on July 1, 1992, as a revision to the 
Oklahoma SIP.
    The EPA has approved two revisions to the ODEQ regulations in the 
Oklahoma SIP in this numbering system submitted after the July 1, 1992, 
submittal. The revisions were submitted to EPA on December 10, 1992, 
and May 16, 1994. Subchapter 31 (OAC:310:200-31), Control of Emissions 
of Sulfur Compounds, adopted by the State March 24, 1993, and submitted 
by the Governor on December 10, 1992, was approved by EPA on July 15, 
1993 (58 FR 38060), at 40 CFR 52.1920(c)(43). Subchapter 23 
(OAC:310:200-23), Control of Emissions from Cotton Gins, adopted by the 
State on March 24, 1993, and submitted by the Governor on May 16, 1994, 
was approved by EPA on May 14, 1997 (62 FR 26393), at 40 CFR 
52.1920(c)(44).

    (Note: The May 16, 1994, submittal of Subchapter 23 
(OAC:310:200-23) was a completely separate submittal from the May 
16, 1994, submittal being acted upon in this action.)

    Before EPA could take action on the recodified regulations 
submitted July 1, 1992, the Air Quality Service, in 1993, became the 
Air Quality Division of the newly created ODEQ. This necessitated the 
transfer of the Air Pollution Control Rules from OAC:310:200 to new 
OAC:252:100. The recodification of the regulations to OAC:252:100 was 
adopted by the Oklahoma Legislature on March 30, 1994, published in the 
Oklahoma Register on May 16, 1994, effective May 26, 1994, and 
submitted by the Governor of Oklahoma to EPA as a revision to the 
Oklahoma SIP on May 16, 1994. There were no substantive changes in the 
regulations. No regulations or revisions to regulations in the Oklahoma 
SIP have been approved under this numbering system.
    The intent of this Federal Register action is to approve the 
regulations in the May 16, 1994, submittal that are equivalent to the 
current SIP-approved regulations. The EPA is taking no action on 
subchapters of the submittal that are not equivalent to the current 
SIP-approved regulations being replaced, or on subchapters that have 
not previously been approved into the SIP.

[[Page 59630]]

III. What Regulations in the May 16, 1994, Submittal Are Not Being 
Acted Upon in This Action?

    Subchapter 8 (Operating Permits), subchapter 11 (Alternative 
Emissions Reduction Permits), subchapter 21 (Particulate Matter 
Emissions from Wood-Waste Burning Equipment), and appendix D 
(Particulate Matter Emission Limits for Wood Waste Burning Equipment) 
are not being acted upon in this action because equivalent regulations 
are not in the current Oklahoma SIP.
    Subchapter 7 (Permits) is not being approved in this recodification 
because it is a substantial revision to the current SIP-approved 
regulation. As a result, the following ODEQ regulation remains in the 
Oklahoma SIP: Regulation 1.4 (Air Resources Management Permits 
Required) as approved by EPA on August 25, 1983 (48 FR 38636), at 
Sec. 52.1920(c)(26); January 31, 1991 (56 FR 03781), at 
Sec. 52.1920(c)(38); and July 23, 1991 (56 FR 33717), at 
Sec. 52.1920(c)(41). This subchapter will be addressed in a future 
rulemaking.
    Subchapter 41 (Control of Emission of Hazardous and Toxic Air 
Contaminants) is not being acted on in this rulemaking because it is 
not equivalent to the current SIP-approved regulations. As a result, 
the following ODEQ regulation remains in the Oklahoma SIP: Regulation 
3.8, (Control of Emission of Hazardous Air Contaminants), as approved 
by EPA on August 15, 1983 (48 FR 36819), at Sec. 52.1920(c)(27).

IV. What Oklahoma SIP Regulations Are Being Replaced by This 
Action?

    The table below cross-references subchapters in the May 16, 1994, 
submittal of OAC:252:100 that EPA is approving in this action with 
previous citations of the regulations. The third (1992) codification is 
not shown because it is identical to the current codification except 
that ``252:100'' in the current codification was ``310:200'' in the 
third codification. The titles shown are the proposed new SIP titles. 
In some cases these titles are different from the current SIP-approved 
titles. The current SIP-approved regulations are shown with an ``*'' 
following the regulation numbers. In some cases, such as new subchapter 
1, parts of two former codifications are in the current SIP. An ``*'' 
in the first column means the current SIP regulations were approved 
under the 1992 ``310-200'' codification.

V. What Changes Have Been Made to the Regulations?

    This section summarizes changes to the regulations initially made 
in OAC:300:200 and carried over into OAC:252:100.

A. Format Changes

    The new numbering system is considerably different from the first 
two numbering systems. A subchapter number has been assigned to the 
group of rules previously identified by regulation numbers. Some 
subchapters are further divided into parts. The numbers initially 
assigned to subchapters and parts are all odd numbers to allow for 
future expansions of the rules.
    Subchapters and parts are divided into groups of related sections. 
A section may be further subdivided into subsections, paragraphs, 
subparagraphs, units, and subunits.

B. Administrative Wording Changes

    The regulations also underwent administrative wording changes 
necessitated by the transfer of the

[[Page 59631]]

administration of the regulations to the newly created ODEQ and the 
resultant transfer of the Oklahoma Air Pollution Control Regulations to 
OAC:252:100 as well as style changes to be consistent with that 
preferred by the State. For example, the term ``Executive Director'' 
replaced the word ``Commissioner'' and the terms ``Chapter'' and 
``Subchapter'' replaced the word ``Regulation.'' Two tables in the 
support document for this action show the administrative wording 
changes versus the terms replaced.

C. Changes to Definition Sections

    Subchapter 1, General Provisions, contains definitions for Chapter 
100. Almost all definitions previously approved by EPA in other ODEQ 
SIP-approved regulations are included in subchapter 1, section 1-3, 
Definitions, as well as in the subchapter, part, or section they apply 
to. Some individual terms and terms with more than one definition in 
section 1-3 are restricted to specific subchapters, parts, or sections.
    All definitions in Chapter 100 have a standard introductory 
paragraph which gives the part or section the definitions pertain to. 
All defined terms are in double quotes followed by the word ``means'' 
followed by the definition of the term. Terms within each definitions 
section have been placed in alphabetical order. Definitions not 
previously approved by EPA in the State General Definitions section 
were approved into the SIP in the Regulations they apply to.

D. Other Changes

    A Purpose section is the first section of each subchapter. Some 
regulations in the earlier codifications did not have a Purpose 
section.
    Most sections and subsections and some paragraphs and subparagraphs 
formerly without titles have been given titles.
    Most of the tables in the old regulations are in appendices at the 
end of Chapter 100. New sections in the subchapters reference the 
tables in the appendices.

VI. Final Action

    The EPA is approving ODEQ Air Pollution Control Rules (OAC:252:100) 
adopted by the State on March 30, 1994, and submitted by the Governor 
on May 16, 1994, except for subchapters 7, 8, 11, 21, 41, and appendix 
D. The regulations being approved replace the current ODEQ regulations 
in the Oklahoma SIP except for Regulation 1.4 (Air Resources Management 
Permits Required) and Regulation 3.8 (Control of Emission of Hazardous 
Air Contaminants). The changes are administrative in nature and do not 
substantively revise the current SIP.
    The EPA is publishing this rule without prior proposal because we 
view this as a noncontroversial amendment and anticipate no adverse 
comments. However, in the ``Proposed Rules'' section of today's Federal 
Register publication, we are publishing a separate document that will 
serve as the proposal to approve the SIP revision if adverse comments 
are received. This rule will be effective on January 3, 2000 without 
further notice unless we receive adverse comment by December 3, 1999. 
If EPA receives adverse comments, we will publish a timely withdrawal 
in the Federal Register informing the public that the rule will not 
take effect. We will address all public comments in a subsequent final 
rule based on the proposed rule. We will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time.

VII. Administrative Requirements

A. Executive Order (E.O.) 12866

    The Office of Management and Budget (OMB) has exempted this 
regulatory action from E.O. 12866, entitled ``Regulatory Planning and 
Review.''

B. Executive Order 12875

    Under E.O. 12875, EPA may not issue a regulation that is not 
required by statute and that creates a mandate upon a State, local or 
tribal government, unless the Federal government provides the funds 
necessary to pay the direct compliance costs incurred by those 
governments, or EPA consults with those governments. If EPA complies by 
consulting, E.O. 12875 requires EPA to provide to the OMB a description 
of the extent of EPA's prior consultation with representatives of 
affected State, local and tribal governments, the nature of their 
concerns, copies of any written communications from the governments, 
and a statement supporting the need to issue the regulation. In 
addition, E.O. 12875 requires EPA to develop an effective process 
permitting elected officials and other representatives of State, local 
and tribal governments ``to provide meaningful and timely input in the 
development of regulatory proposals containing significant unfunded 
mandates.''
    Today's rule does not create a mandate on State, local, or tribal 
governments. The rule does not impose any enforceable rules on any of 
these entities. This action does not create any new requirements but 
simply approves requirements that the State is already imposing. 
Accordingly, the requirements of section 1(a) of E.O. 12875 do not 
apply to this rule.

C. Executive Order 13045

    Executive Order 13045, entitled ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997), applies to any rule that: (1) is determined to be ``economically 
significant'' as defined under E.O. 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    The EPA interprets E.O. 13045 as applying only to those regulatory 
actions that are based on health or safety risks, such that the 
analysis required under section 5-501 of the Order has the potential to 
influence the regulation. This final rule is not subject to E.O. 13045 
because it approves a State program.

D. Executive Order 13084

    Under E.O. 13084, EPA may not issue a regulation that is not 
required by statute, that significantly or uniquely affects the 
communities of Indian tribal governments, and that imposes substantial 
direct compliance costs on those communities, unless the Federal 
government provides the funds necessary to pay the direct compliance 
costs incurred by the tribal governments, or EPA consults with those 
governments. If EPA complies by consulting, E.O. 13084 requires EPA to 
provide to the OMB, in a separately identified section of the preamble 
to the rule, a description of the extent of EPA's prior consultation 
with representatives of affected tribal governments, a summary of the 
nature of their concerns, and a statement supporting the need to issue 
the regulation. In addition, E.O. 13084 requires EPA to develop an 
effective process permitting elected officials and other 
representatives of Indian tribal governments ``to provide meaningful 
and timely input in the development of regulatory policies on matters 
that significantly or uniquely affect their communities.''
    Today's rule does not significantly or uniquely affect the 
communities of Indian tribal governments. This action does not involve 
or impose any requirements that affect Indian tribes. Accordingly, the 
requirements of

[[Page 59632]]

section 3(b) of E.O. 13084 do not apply to this rule.

E. Regulatory Flexibility Act

    The Regulatory Flexibility Act, 5 U.S.C. 600 et seq., generally 
requires an agency to conduct a regulatory flexibility analysis of any 
rule subject to notice and comment rulemaking requirements unless the 
agency certifies that the rule will not have a significant economic 
impact on a substantial number of small entities. Small entities 
include small businesses, small not-for-profit enterprises, and small 
governmental jurisdictions. This final rule will not have a significant 
impact on a substantial number of small entities because SIP approvals 
under section 110 and subchapter I, part D of the Federal Clear Air Act 
(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 create any new requirements, I certify 
that this action will not have a significant economic impact on a 
substantial number of small entities. Moreover, due to the nature of 
the Federal-State relationship under the Act, preparation of a 
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, 255-66 (1976); 42 U.S.C. 7410(a)(2).

F. 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 annual costs to State, 
local, or tribal governments in the aggregate; or to private sector, of 
$100 million or more. Under section 205, 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 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 annual 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 requirements. Accordingly, no additional costs to State, 
local, or tribal governments, or to the private sector, result from 
this action.

G. Submission to Congress and the Comptroller General

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit 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 United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major'' rule as defined by 5 U.S.C.
