ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN45-3a; FRL-5698-5]


Approval and Promulgation of Implementation Plans; Indiana

AGENCY: Environmental Protection Agency (USEPA).

ACTION: Direct final rule.

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

SUMMARY: On September 20, 1996, Indiana submitted a request to 
incorporate revisions to the definitions of ``nonphotochemically 
reactive hydrocarbon'' and ``volatile organic compounds'' (VOC) into 
the Indiana State Implementation Plan (SIP). The term ``VOC'' denotes 
chemical compounds which react with nitrogen dioxide (NO2) and 
sunlight to form ozone. The term ``nonphotochemically reactive 
hydrocarbon'' refers to chemical compounds which USEPA has determined 
will not react with NO2 and sunlight to form ozone. In this 
action, USEPA is approving the State's request to incorporate into the 
SIP the revisions to these definitions through a ``direct final'' 
rulemaking; the rationale for this approval is set forth below. Part of 
this submittal is in response to USEPA's May 4, 1995 conditional 
approval of the State's VOC definition. Among other things, in this 
rulemaking, USEPA is finding that the condition identified in USEPA's 
May 4, 1995 action have been satisfied; therefore, USEPA is converting 
the conditional approval to a full approval. Elsewhere in this Federal 
Register, USEPA is proposing approval and soliciting comment on these 
direct final actions; if adverse comments are received, USEPA will 
withdraw the direct final rule and address the comments received in a 
new final rule; otherwise, no further rulemaking will occur on the 
State's request to incorporate revisions to these definitions into the 
Indiana SIP.

DATES: This action will be effective June 17, 1997 unless adverse 
comments not previously addressed by the State or USEPA are received by 
May 19, 1997. If the effective date of this action is delayed due to 
adverse comments, timely notice will be published in the Federal 
Register.

ADDRESSES: Written comments should be sent to: J. Elmer Bortzer, Chief, 
Regulation Development Section, Air Programs Branch (AR-18J), U.S. 
Environmental Protection Agency, 77 West Jackson Boulevard, Chicago, 
Illinois 60604.
    Copies of the Indiana submittal are available for public review 
during normal business hours, between 8:00 a.m. and 4:30 p.m., at the 
above address. A copy of this SIP revision is also available for 
inspection at: Office of Air and Radiation (OAR) Docket and Information 
Center (Air Docket 6102), Room 1500, U.S. Environmental Protection 
Agency, 401 M Street, S.W., Washington, D.C. 20460.

SUPPLEMENTARY INFORMATION:

I. Background

    1. On May 4, 1995 (60 FR 22241), USEPA conditionally approved as a 
SIP revision the State of Indiana's modified definition of 
``nonphotochemically reactive hydrocarbon'' at Title 326 Indiana 
Administrative Code (326 IAC) 1-2-48 and of ``VOC'' at 325 IAC 1-2-90. 
The intention of these revisions was to comport with the February 2, 
1992 revisions to the Federal definition of ``VOC'' (57 FR 3945). In 
addition to making the changes authorized by the revised Federal 
definition, Indiana also added ``vegetable oils'' as an exclusion to 
the VOC definition. This additional exclusion was added at the request 
of commentors who cited August 21,1990 and August 4, 1992 EPA policy 
memoranda in support of their request. As discussed more fully in the 
May 4, 1995 rulemaking, this exclusion was not consistent with Federal 
requirements. By letter dated December 14, 1994, Indiana committed to 
the necessary rule revision to correct this identified deficiency, thus 
providing the basis for the Agency's conditional approval.
    2. In addition, on October 5, 1994 (59 FR 3945), USEPA excluded two 
compounds determined to be negligibly photochemically reactive from the 
Federal definition of VOC--''parachlorobenzotrifluoride'' (PCBTF) and 
``cyclic, branched, or linear completely methylated siloxanes.'' In 
response to this Federal action, Indiana modified its definition of 
``nonphotochemically reactive hydrocarbon'' at 326 IAC 1-2-48 to 
include these two compounds.
    3. The September 20, 1996 SIP revision request also includes an 
additional change to the State's definition of ``nonphotochemically 
reactive hydrocarbon'' at 326 IAC 1-2-48--the addition of ``acetone.'' 
This modification reflects USEPA's June 16, 1995 (60 FR 31634) final 
rule which added acetone to the list of organic chemicals considered to 
have negligible photochemical reactivity.
    4. By this direct final rule, USEPA finds that the conditions of 
USEPA's May 4, 1995 rulemaking have been satisfied. The conditional 
approval is, therefore, converted to a full approval. Furthermore, the 
additional definitional revisions submitted by Indiana are consistent 
with the applicable Federal definition and are, therefore, approvable.

II. Rulemaking Action

    Because the Indiana SIP revision requests are consistent with 
changes to the Federal requirements, USEPA is approving them for 
incorporation in the Indiana SIP. The deletion of the exclusion of 
``vegetable oil'' from the definition of ``VOC'', codified at 326 IAC 
1-2-90, satisfies USEPA's May 4, 1995 (60 FR 22241) conditional 
approval of 326 IAC 1-2-48 and 1-2-90, and means that ``vegetable oil'' 
will be regulated as a ``VOC.''. The approval of these rules supersedes 
USEPA's earlier conditional approval of them.
    The USEPA is publishing this action without prior proposal because 
USEPA views this as a noncontroversial revision and anticipates no 
adverse comments. However, in a separate document in this Federal 
Register publication, the USEPA is proposing to approve the SIP 
revision should adverse or critical comments be filed. This action will 
be effective on June 17, 1997 unless, by May 19, 1997, adverse or 
critical comments are received.
    If the USEPA receives such comments, this action will be withdrawn 
before the effective date by publishing a subsequent rulemaking 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 USEPA 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 comments are received, the public is 
advised that this action will be effective on June 17, 1997.
    Nothing in this action should be construed as permitting, 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, economic, and environmental 
factors and in relation to relevant statutory and regulatory 
requirements.

III. Administrative Requirements

A. Executive Order 12866

    This action has been classified as a Table 3 action for signature 
by the

[[Page 19056]]

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 D. Nichols, Assistant Administrator for 
Air and Radiation. The Office of Management and Budget (OMB) has 
exempted this regulatory action from Executive Order 12866 review.

B. Regulatory Flexibility.

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., USEPA 
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, USEPA 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 (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 Act, preparation of a flexibility 
analysis would constitute Federal inquiry into the economic 
reasonableness of the State action. The Act forbids USEPA to base its 
actions concerning SIPs on such grounds. Union Electric Co. v. 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, USEPA must undertake various actions 
in association with 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 the private sector, of $100 million 
or more. This Federal action approves pre-existing requirements under 
state or local law, and imposes no new Federal requirements. 
Accordingly, no additional costs to state, local, or tribal 
governments, or the private sector, result from this action.

D. Submission to Congress and the General Accounting Office

    Under 5 section 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, USEPA 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 the rule in today's 
Federal Register. This rule is not a major rule as defined by 5 section 
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 June 17, 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)).
