**Approval and Promulgation of Air Quality Implementation Plans;**  **Louisiana; Revisions To Control Volatile Organic Compound Emissions**  **for Surface Coatings and Graphic Arts**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve State Implementation Plan (SIP) revisions for control of volatile organic compounds (VOCs) adopted by Louisiana on June 20, 2009 and August 20, 2010, and submitted to EPA on August 31, 2010. EPA is also proposing to approve a SIP revision for control of emission of organic compounds which was proposed by Louisiana on January 20, 1011. EPA issued Control Techniques Guidelines (CTGs) in 2006, 2007 and 2008; Louisiana’s rule revisions being proposed for approval in this action were developed in response
to these CTGs. Because Louisiana has not yet finalized the January 20th revision to the VOC rules, we are proposing to approve this SIP revision in parallel with Louisiana’s rulemaking
activities. If the final version of the VOC rule adopted by Louisiana is changed from the proposed version which is being ‘‘ parallel processed’’ today, EPA will withdraw this rulemaking and propose a new rulemaking with the final VOC rule adopted by Louisiana. If there are no changes to the ‘‘ parallelprocessed’’ version, EPA will proceed with final rulemaking on the version finally adopted by Louisiana and submitted to EPA. EPA is proposing to approve these revisions because they enhance the Louisiana SIP by improving
VOC emission controls in Louisiana. EPA is also proposing to find that these revisions meet Reasonably Available Control Technology (RACT) requirements. These revisions meet statutory and regulatory requirements, and are consistent with EPA’s guidance. This action is being taken under section 110 and part D of the Clean Air Act (CAA).

Outline

I. What action is EPA proposing?
II. What is ‘‘ parallel processing ’’ , and why are we using it to process a Louisiana

revision? III. Why is EPA proposing this action? IV. What are the requirements of Louisiana’s
VOC rule revisions? V. Statutory and Executive Order Reviews

I. What action is EPA proposing?

EPA is proposing to approve SIP
revisions for control of emission of organic compounds adopted by Louisiana on June 20, 2009, and August 20, 2010, and submitted to EPA on August 31, 2010. We are also proposing to approve, by parallel processing, a
revision for control of emission of organic compounds proposed by Louisiana on January 20, 2010. The revisions submitted on August 31, 2010, are included as Appendices A and B of the LDEQ submittal entitled, ‘‘VOC RACT Control Technique Guidelines ’’ dated August 2010. Together, these revisions include updates to the following Louisiana rules: Chapter 1 General Provisions, amendments to § 111 Definitions; Chapter 21 Control of Emission of Organic Compounds, amendments to § 2123 Organic Solvents, and § 2143 Graphic Arts (Printing) by Rotogravure, Flexographic, Offset Lithographic, Letterpress, and Flexible Package Printing Processes. Also, EPA is proposing to approve, by parallel processing, the VOC rule revision proposed January 20, 2011, which is a small wording change. In a letter to EPA dated February 7, 2011, the State of Louisiana requested ‘‘ parallel processing ’’ and a provided a schedule for final adoption of this VOC rule

revision.

We are proposing to approve these revisions because they enhance the Louisiana SIP by improving control of
emissions from VOC sources in
Louisiana. These revisions reflect changes in response to CTGs issued in 2006, 2007 and 2008: Consumer and Commercial Products Group II: Control Techniques Guidelines in Lieu of Regulations for Flexible Packaging Printing Materials, Lithographic Printing Materials, Letterpress Printing Materials, Industrial Cleaning Solvents, and Flat Wood Paneling Coatings (71 FR 58745, October 5, 2006); Consumer and
Commercial Products: Control Techniques Guidelines in Lieu of Regulations for Paper, Film, and Foil Coatings; Metal Furniture Coatings; and Large Appliance Coatings (72 FR 57215, October 9, 2007); Consumer and Commercial Products, Group IV: Control Techniques guidelines in Lieu of Regulations for Miscellaneous Metal Products Coatings, Plastic Parts Coatings, Auto and Light-Duty Truck Assembly coatings, Fiberglass Boat Manufacturing Materials, and Miscellaneous Industrial Adhesives (73 FR 58481, October 7, 2008).

In addition, we are proposing that
these revisions meet RACT requirements for these source categories. These revisions meet statutory and regulatory requirements, and are consistent with EPA’s guidance. EPA is proposing approval of these revisions pursuant to section 110 and part D of
the CAA.

II. What is ‘‘parallel processing’’ , and why are we using it to process a

Louisiana revision?

At the request of the State of Louisiana, approval of its revision, published in the Louisiana Register January 20, 2011, is being proposed under a procedure called ‘‘ parallel processing ’’ whereby EPA proposes rulemaking action concurrently with the State’s procedures for amending its regulations (40 CFR part 51, Appendix V, section 2.3).

Under parallel processing, EPA proposes rulemaking action concurrently with the State’s proposed rulemaking. If the State’s proposed revision is changed, EPA will evaluate that subsequent change and may publish another notice of proposed rulemaking. If no change is made, EPA will publish a final rulemaking on the revisions after responding to any submitted comments. Final rulemaking


### 14604 Federal Register / Vol. 76, No. 52 / Thursday, March 17, 2011 / Proposed Rules

action by EPA will occur only after the SIP revision has been fully adopted by Louisiana and submitted formally to EPA for incorporation into the SIP. In addition, any action by the State resulting in undue delay in the adoption of the rules may result in a re-proposal, altering the approvability of this SIP revision. The parallel processing of the January 20, 2011 revision is appropriate
because it accommodates a minor wording change and no further change is anticipated. The State’s January 20, 2011, proposed revision and their letter of February 7, 2011 are available in the
docket for this action.

III. Why is EPA proposing this action?

A primary purpose of these rules is to improve control of VOC emissions in various parishes in Louisiana. Our approval of the revised Louisiana regulations will make them federally enforceable. Also, these rules satisfy the requirement to adopt VOC RACT rules for the CTG documents issued by EPA in 2006, 2007, and 2008.

These revised requirements for control of VOC emissions will help to
attain and maintain the 8-hour ozone standard in Louisiana parishes. These rules satisfy in part the requirement in
the Clean Air that VOC RACT rules be adopted for ozone nonattainment areas. This includes the Baton Rouge 8-hour

ozone nonattainment area. Sections 172(c)(1) and 182 of the Act require
areas that are classified as moderate or above for ozone nonattainment to adopt RACT requirements for sources that are subject to CTGs issued by EPA and for

‘‘major sources ’’ of VOCs and nitrogen oxides (NO X ), which are ozone

precursors. See 42 U.S.C. sections 7502 (c)(1) and 7511a (b) and (f). RACT is
defined as the lowest emissions limitation that a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility (44 FR 53762; September 17, 1979). A CTG provides
information on the available controls for a source category and provides
information about RACT for the category.

As discussed previously, EPA issued new CTGs in 2006, 2007 and 2008. EPA
has reviewed Louisiana’s new VOC rule revisions with respect to RACT requirements and the recommendations in the new CTGs and proposes to find
that these revisions meet RACT. Based on our analysis, we find that these VOC rule revisions enhance the SIP by providing clarification and additional control requirements for reducing emissions from volatile organic compounds, and also that these revisions meet RACT requirements. EPA is proposing to find that for the CTG categories included in this rule-making,
Louisiana has RACT-level controls.
Additional information about RACT and
EPA’s evaluation of Louisiana’s rule
revisions for RACT for this action is provided in the TSD, including TSD Appendix B. In a related but separate rulemaking, EPA plans to evaluate the RACT/RACM submittal provided by Louisiana on August 31, 2010. This will include analysis of RACT for NO X and also for VOC categories other than thoseincluded here, as well as RACT for nonmajor sources.

IV. What are the requirements of
Louisiana’s VOC rule revisions?

This proposed approval of Louisiana’s
VOC rule revisions affects Louisiana’s rules in both Chapter 1 General Provisions and Chapter 21 Control of Emission of Organic Compounds, specifically Chapter 1 § 111 Definitions, Chapter 21 Subchapter B. Surface Coatings § 2123 Organic Solvents, and Subchapter H. Graphic Arts § 2143 Graphic Arts (Printing) by Rotogravure, Flexographic, Offset Lithographic, Letterpress, and Flexible Package Printing Processes. Applicability under these rules includes requirements that vary by parish, and is briefly discussed below. Louisiana’s Chapter 1 definitions, and Chapter 21 controls for VOC emissions, cover many categories of sources. This rulemaking affects sources covered by the Louisiana Administrative Code (LAC) Chapters and Subchapters listed in the following table. However, to determine whether a specific facility in a Louisiana parish will be affected by one or more of the above revisions, please see Louisiana’s
associated rule revisions included in the
docket.

V. Statutory and Executive Order

Reviews

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet
the criteria of the Clean Air Act. Accordingly, this action merely proposes to approve State law as meeting Federal requirements and does not impose additional requirements beyond those imposed by State law. For that reason, this action:

• Is not a ‘‘ significant regulatory

action’’ subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44

U.S.C. 3501 et seq. );

• Is certified as not having a significant economic impact on a
substantial number of small entities under the Regulatory Flexibility Act (5

U.S.C. 601 et seq. );

• 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);

• Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);

• Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act;
and

• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

In addition, this proposed rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing to approve the State Implementation Plan (SIP) submission submitted by the State of South Carolina, through the Department
of Health and Environmental Control (DHEC), to demonstrate that the State meets the requirements of sections 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 1997 8-hour ozone national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation,
maintenance and enforcement of each NAAQS promulgated by the EPA, which is commonly referred to as an

‘‘ infrastructure ’’ SIP. South Carolina
certified that the South Carolina SIP contains provisions that ensure the 1997 8-hour ozone NAAQS are implemented, enforced, and maintained in South Carolina (hereafter referred to as

‘‘ infrastructure submission’’ ). South Carolina’s infrastructure submission, provided to EPA on December 13, 2007, addressed all the required infrastructure
elements for the 1997 8-hour ozone NAAQS.
