Approval and Promulgation of Implementation Plans; South 
Carolina: Revisions to State Implementation Plan; Clarification

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; clarification.

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

SUMMARY: EPA is clarifying its approval of revisions to the South 
Carolina State Implementation Plan (SIP), published in the Federal 
Register on December 7, 2006. EPA's action modified South Carolina's 
federally approved Regulation 61-62.1 ``Definitions and General 
Requirements,'' by revising the definition of Volatile Organic 
Compounds (VOC). This action merely clarifies the list of compounds 
which are excluded from the definition of VOC.

DATES: This action is effective June 4, 2007.

ADDRESSES: EPA has established a docket for this action under Docket 
Identification No. EPA-R04-OAR-2005-SC-0005. All documents in the

SUPPLEMENTARY INFORMATION: 

I. What Is the Background for This Action?

    Through a direct final rulemaking, published in the Federal 
Register on December 7, 2006, (71 FR 70880), EPA approved revisions to 
the South Carolina SIP. These revisions were submitted on October 24, 
2005, by the South Carolina Department of Health and Environmental 
Control (SC DHEC). The purpose of EPA's action was to revise the 
definition of VOC. Specifically, that SIP revision updated the 
nomenclature for compounds excluded from the definition of VOC in SC 
Regulation 61-62.1, to be consistent with the Federal rule published on 
November 29, 2004, (69 FR 69298). It also added four compounds to the 
list of those excluded from the definition of VOC, on the basis that 
they make a negligible contribution to ozone formation, also consistent 
with the Federal rule. Additionally, the revision added the compound t-
butyl acetate (TBAC or TBAc) to the list of compounds excluded from the 
definition of VOC for purposes of emissions limitations or VOC content 
requirements. EPA is clarifying the action taken on December 7, 2006, 
due to feedback that the rulemaking was not clear in its intent.

II. EPA's Action

    The purpose of this action is only to clarify a previous action and 
no substantial changes are being made. Below is the list of the 
compounds presented in the December 7, 2006, rulemaking, which updates 
the nomenclature for the following compounds excluded from the 
definition of VOC in the South Carolina SIP:
     (CF3) 
2CFCF2OC2H5 to (2-
(ethoxydifluoromethyl)-(1,1,1,2,3,3,3-heptafluoropropane)
     CFC-113 (1,1,2-trichloro-1,2,2-trifluoroethane)
     CFC-114 (1,2-dichloro-1,1,2,2-tetrafluoroethane)
     HCFC-123 (1,1,1-trifluoro-2,2-dichloroethane)
     HCFC-134a (1,1,1,2-tetrafluoroethane)
     HCFC-141b (1,1-dichloro-1-fluoroethane)
     HCFC-142b (1-chloro-1,1-difluoroethane)
     HFE-7100 (1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxybutane) or 
(C4F9OCH3)

[[Page 30705]]

     HFE-7200 (1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane) or 
(C4F9OC2H5)
     Methylene chloride (dichloromethane)
     Perchloroethylene (tetrachloroethylene); and 
perfluorocarbon compounds that fall into these classes:
    (i) Cyclic, branched, or linear, completely fluorinated alkanes;
    (ii) cyclic, branched, or linear, completely fluorinated alkanes;
    (iii) cyclic, branched, or linear, completely fluorinated ethers 
with no unsaturations;
    (iv) sulfur containing perfluorocarbons with no unsaturations and 
with sulfur bonds only to carbon and fluorine.

Additionally, the 2006 action added the following five compounds to the 
list of those excluded from the definition of VOC:

     HFE-7000 (1,1,1,2,2,3,3-heptafluoro-3-methoxy-propane) or 
(n-C3F7OCH3)
     HFE-7500 (3-ethoxy-1,1,1,2,3,4,4,5,5,6,6,6-dodecafluoro-2-
(trifluoromethyl) hexane
     HFC-227ea (1,1,1,2,3,3,3-heptafluoropropane)
     Methyl formate (HCOOCH3)
     The following compound(s) are defined as VOC only for 
purposes of all recordkeeping, emissions reporting, photochemical 
dispersion modeling and inventory requirements that apply to VOC and 
shall be uniquely identified in emission reports; they are not, 
however, defined as VOC for purposes of VOC emissions limitations or 
VOC content requirements: T-butyl acetate (TBAC or TBAc).
    EPA has determined that today's action falls under the ``good 
cause'' exemption in section 553(b)(3)(B) of the Administrative 
Procedure Act (APA) which, upon finding ``good cause,'' authorizes 
agencies to dispense with public participation where public notice and 
comment procedures are impracticable, unnecessary, or contrary to the 
public interest. Public notice and comment for this action are 
unnecessary because today's action to provide clarification of those 
compounds exempted from the definition of VOC, has no substantive 
impact on EPA's December 7, 2006, approval. The clarification for the 
list of compounds exempted from the definition of VOC, in EPA's direct 
final rule published on December 7, 2006, makes no substantive 
difference to EPA's analysis as set out in that rule. In addition, EPA 
can identify no particular reason why the public would be interested in 
being notified of this clarification or in having the opportunity to 
comment on the clarification prior to this action being finalized, 
since this clarification action does not change EPA's analysis for the 
update to the nomenclature for those compounds excluded from the 
definition of VOC, and the addition of five compounds to the list of 
those excluded from the definition of VOC.
    EPA also finds that there is good cause under APA section 553(d)(3) 
for this clarification to become effective on the date of publication 
of this action. Section 553(d)(3) of the APA allows an effective date 
less than 30 days after publication ``as otherwise provided by the 
agency for good cause found and published with the rule.'' 5 U.S.C. 
553(d)(3). The purpose of the 30-day waiting period prescribed in APA 
section 553(d)(3), is to give affected parties a reasonable time to 
adjust their behavior and prepare before the final rule takes effect. 
Today's rule, however, does not create any new regulatory requirements 
such that affected parties would need time to prepare before the rule 
takes effect. Rather, today's rule simply clarifies EPA's December 7, 
2006, rulemaking. For these reasons, EPA finds good cause under APA 
section 553(d)(3), for this clarification to become effective on the 
date of publication of this action.

III. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. For this 
reason, this action is also not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action 
merely clarifies the nomenclature and the list of compounds excluded 
from the definition of VOC in the South Carolina SIP as approved in 
EPA's December 7, 2006, rulemaking, and imposes no additional 
requirements beyond those imposed by state law. Accordingly, the 
Administrator certifies that this rule will not have a significant 
economic impact on a substantial number of small entities under the 
Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule 
clarifies the nomenclature and the list of compounds excluded from the 
definition of VOC in the South Carolina SIP as approved in EPA's 
December 7, 2006, rulemaking, notice and does not impose any additional 
enforceable duty beyond that required by state law, it does not contain 
any unfunded mandate or significantly or uniquely affect small 
governments, as described in the Unfunded Mandates Reform Act of 1995 
(Pub. L. 104-4).
    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000). This action also does not have Federalism 
implications because it does not have substantial direct effects on the 
states, on the relationship between the national government and the 
states, or on the distribution of power and responsibilities among the 
various levels of government, as specified in Executive Order 13132 (64 
FR 43255, August 10, 1999). This action merely clarifies the 
nomenclature and the list of compounds excluded from the definition of 
VOC in the South Carolina SIP as approved in EPA's December 7, 2006, 
rulemaking, and does not alter the relationship or the distribution of 
power and responsibilities established in the CAA. This rule also is 
not subject to Executive Order 13045, ``Protection of Children from 
Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 
1997), because it is not economically significant.
    In reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the CAA. In this 
context, in the absence of a prior existing requirement for the State 
to use voluntary consensus standards (VCS), EPA has no authority to 
disapprove a SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP submission that otherwise 
satisfies the provisions of the CAA. Thus, the requirements of section 
12(d) of the National Technology Transfer and Advancement Act of 1995 
(15 U.S.C. 272 note) do not apply. This rule does not impose an 
information collection burden under the provisions of the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    The Congressional Review Act, U.S.C. section 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. EPA will submit a report containing this 
rule and other

[[Page 30706]]

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. 
804(2).
    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 3, 2007. 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)).
