(a) Section 6.7 of Regulation 6.0 is disapproved since it could conflict with the preconstruction requirements for the prevention of significant deterioration (PSD) of air quality.

(b) Section 6.9 of Regulation 6.0 is disapproved since it could conflict with the preconstruction requirements for the prevention of significant deterioration (PSD) of air quality and the Administrator's Interpretative on Rule of December 21, 1976.

[44 FR 18491, Mar. 28, 1979, as amended at 47 FR 6017, Feb. 10, 1982]

(a) Determination of Attainment. Effective March 12, 2010 EPA has determined the Baton Rouge 1-hour ozone nonattainment area has attained the 1-hour ozone National Ambient Air Quality Standard (NAAQS). Under the provisions of EPA's Clean Data Policy, this determination suspends the requirements for this area to submit a severe attainment demonstration, a severe reasonable further progress plan, applicable contingency measures plans, and other planning Louisiana State Implementation Plan (SIP) requirements related to attainment of the 1-hour ozone NAAQS for so long as the area continues to attain the 1-hour ozone NAAQS.

(b) Determination of Attainment. Effective October 12, 2010 EPA has determined that the Baton Rouge 8-hour ozone nonattainment area has attained the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS). Under the provisions of 40 CFR 51.918 this determination suspends the requirements for this area to submit an attainment demonstration, a reasonable further progress plan, applicable contingency measures, and other planning Louisiana State Implementation Plan (SIP) requirements related to attainment of the 1997 8-hour ozone NAAQS for so long as the area continues to attain the 1997 8-hour ozone NAAQS.

(c) Determination to Terminate the Clean Air Act Section 185 Penalty Fee Requirement. Effective September 6, 2011 EPA has determined that the State of Louisiana is no longer required to submit a section 185 fee program State Implementation Plan (SIP) revision for the Baton Rouge ozone nonattainment area to satisfy anti-backsliding requirements for the 1-hour ozone standard. This determination is based on EPA's determination that the area has attained the 1-hour ozone standard due to permanent and enforceable emissions reductions.

(d) Redesignation for the 1997 8-hour Ozone Standard. Effective December 30, 2011, EPA has redesignated the Baton Rouge area to attainment for the 1997 8-hour ozone standard. With this final redesignation to attainment for the 1997 8-hour ozone NAAQS and the final determination of attainment for the 1-hour ozone NAAQS in paragraph (a) of this section, the 1-hour anti-backsliding obligations to submit planning SIPs to meet the attainment demonstration and reasonably available control measures requirements, the rate of progress and contingency measures requirements, and any other outstanding 1-hour requirements, cease to apply.

(e) Clean Data Determination. Effective June 16, 2014 EPA has determined that the Baton Rouge, Louisiana, marginal 2008 8-hour ozone nonattainment area is currently attaining the 2008 8-hour NAAQS for ozone.

(f) The EPA has determined that the Baton Rouge Marginal 2008 ozone NAAQS nonattainment area attained the NAAQS by the applicable attainment date of July 20, 2015.

[75 FR 6575, Feb. 10, 2010, as amended at 75 FR 54779, Sept. 9, 2010; 76 FR 39777, July 7, 2011; 76 FR 74002, Nov. 30, 2011; 79 FR 21142, Apr. 15, 2014; 81 FR 26709, May 4, 2016]

The State of Louisiana has committed to submit to EPA a SIP revision whenever a new or revised emission limitation for a specific source exceeds the height allowed by Section 921(A) “Good Engineering Practice (GEP) Stack Height 1 or 2” of the State regulations. A letter from the Secretary of Louisiana Department of Environmental Quality, dated September 23, 1986, stated that:

In specific, the State regulation, Section 17.14.2 [now LAC 33: Part III, Section 921(B)], provides that the degree of emission limitation required of any source for control of any air pollutant must not be affected by so much of any source's stack height that exceeds good engineering practice or by any other dispersion technique. In reference to this requirement, the Louisiana Department of Environmental Quality or the Administrative Authority will submit to EPA a SIP revision whenever the Louisiana Department of Environmental Quality adopts a new or revised emission limitation for a specific source that is based on a stack height that exceeds the height allowed by Section 17.14.1(e)(1) [now LAC 33: Part III, Section 921(A) “Good Engineering Practice (GEP) Stack Height 1”] or Section 17.14.1(e)(2) [now LAC 33: Part III, Section 921(A) “Good Engineering Practice (GEP) Stack Height 2”].

[59 FR 32360, June 23, 1994]

(a) The Louisiana Department of Environmental Quality submitted to the EPA on August 5, 1994, a petition requesting that the nonclassifiable ozone nonattainment areas in the State of Louisiana be exempted from the requirement to meet the NOX provisions of the Federal transportation conformity rule. The exemption request was based on monitoring data which demonstrated that the National Ambient Air Quality Standard for ozone had been attained in this area for the 3 years prior to the petition. The parishes for which the NOX exemption was requested include: Beauregard, Grant, Lafayette, Lafourche, Jefferson, Orleans, St. Bernard, St. Charles, St. James, and St. Mary. The EPA approved this exemption request on March 2, 1995.

(b) The LDEQ submitted to the EPA on November 17, 1994, a petition requesting that the Baton Rouge serious ozone nonattainment area be exempted from the NOX control requirements of the CAA. In addition, supplemental information was submitted to the EPA by the LDEQ on January 26, 1995, June 6, 1995, and June 16, 1995. The Baton Rouge nonattainment area consists of East Baton Rouge, West Baton Rouge, Pointe Coupee, Livingston, Iberville, and Ascension Parishes. The exemption request was based on photochemical grid modeling which shows that reductions in NOX would not contribute to attainment in the nonattainment area. On January 18, 1996, the EPA approved the State's request for an areawide exemption from the following requirements: NOX new source review, NOX reasonably available control technology, NOX general conformity, and NOX inspection and maintenance requirements.

(c) The LDEQ submitted to the EPA on July 25, 1995, a revision to the SIP, pursuant to section 182(b)(1), requesting that the Baton Rouge serious ozone nonattainment area be exempted from the transportation conformity NOX requirements of the CAA. The Baton Rouge nonattainment area consists of East Baton Rouge, West Baton Rouge, Pointe Coupee, Livingston, Iberville, and Ascension Parishes. The exemption request was based on photochemical grid modeling which shows that additional reductions in NOX would not contribute to attainment in the nonattainment area. On February 12, 1996, the EPA approved the State's request for an areawide exemption from the transportation conformity NOX requirements.

(d) The LDEQ submitted to the EPA on October 28, 1994, a petition requesting that the Lake Charles marginal ozone nonattainment area be exempted from the NOX control requirements of the Act. The Lake Charles nonattainment area consists of Calcasieu Parish. The exemption request was based on photochemical grid modeling which shows that reductions in NOX would not contribute to attainment in the nonattainment area. On May 27, 1997, the EPA approved the State's request for an area-wide exemption from the following requirements: NOX new source review, NOX general conformity, and NOX transportation conformity requirements. The waiver was granted on the basis of modeling, and ambient air quality data demonstrating the area has attained the ozone NAAQS.

(e) On September 24, 2001, and on December 31, 2001, the LDEQ requested that EPA rescind the Baton Rouge section 182(f) and 182(b)(1) NOX exemptions that were approved by EPA, and published in the Federal Register on January 26, 1996 (61 FR 2438), and February 27, 1996 (61 FR 7218). The State based its request on photochemical grid modeling recently performed for the Baton Rouge State Implementation Plan (SIP) which indicates that controlling NOX sources will assist in bringing the Baton Rouge area into attainment with the National Ambient Air Quality Standard (NAAQS) for ozone. On May 7, 2002, EPA proposed approval of the State's request to rescind both NOX exemptions. Based on our review of the State's request and the supporting photochemical grid modeling the NOX exemptions are rescinded on May 5, 2003.

(72) Revisions to the Louisiana SIP addressing VOC RACT Negative Declarations. The Governor of Louisiana submitted the negative declarations for reasonably available control technology (RACT) for the Baton Rouge ozone nonattainment area on December 15, 1996. Section 172(c)(1) of the Clean Air Act requires nonattainment areas to adopt, at a minimum, RACT to reduce emissions from existing sources. Pursuant to section 182(b)(2) of the Act, for moderate and above ozone nonattainment areas, the EPA has identified 13 categories for such sources and developed the Control Technique Guidelines (CTGs) or Alternate Control Techniques (ACTs) documents to implement RACT at those sources. When no major volatile organic compound (VOC) sources for a CTG/ACT category exist in a nonattainment area, a State may submit a negative declaration for that category. Louisiana's submittal included two negative declaration letters from Mr. Gustave Von Bodungen to Ms. Karen Alvarez dated April 6, 1994, and June 20, 1994, for the following source categories: offset lithography, plastic parts-business machines, plastic parts-others, wood furniture, aerospace coatings, autobody refinishing, and shipbuilding coatings/repair. This submittal satisfies section 182(b)(2) of the Clean Air Act Amendments of 1990 for these particular CTG/ACT source categories for the Baton Rouge ozone nonattainment area.
