 Environmental Protection Agency 40 CFR Part 81
[EPA-R09-OAR-2012-0189; FRL-9649-1]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule; technical amendments.
 SUMMARY: EPA is making technical amendments to the Code of Federal Regulations (CFR) to reflect the final actions published by the Agency on October 7, 2003, April 30, 2004, and May 5, 2010 in connection with the designations and classifications of certain areas in California for the 1971 annual nitrogen dioxide standard and the 1997 eight-hour ozone standard pursuant to the Clean Air Act. The areas that are the subject of these technical amendments include Riverside County, Western Mojave Desert, South Coast Air Basin, Eastern Kern County, and San Diego County.
 DATES: These technical amendments are effective on March 21, 2012.

SUPPLEMENTARY INFORMATION: Technical Amendment for California—NO2
                     Table in 40 CFR 81.305 In today's action, we are making a technical amendment to correct an erroneous codification of our 2003 boundary change rule with respect to the “California—NO2
                     (1971 Annual Standard)” table in 40 CFR 81.305.[1]
                    
                     As described in our October 7, 2003 final rule (68 FR at 57821 and 57824) redesignating certain air quality planning area boundaries in southern California, we intended to revise the entry in the table for “Riverside County (portion within SE. Desert AQMD) County” to “Riverside County (Coachella Valley planning area)” and to revise the entry for “Riverside County, non-AQMA portion County” to “Riverside County (portion not within South Coast Air Basin or Coachella Valley planning area).” However, the entry for “Riverside County (Coachella Valley planning area),” which was to become an entry in the table, is not found in the current version of the “California—NO2
                     (1971 Annual Standard)” table whereas the entry for “Riverside County, non-AQMA portion County,” which was intended to be replaced, remains in the table. In today's action, we are making a technical amendment to ensure that the “California—NO2
                     (1971 Annual Standard)” table in 40 CFR 81.305 to accurately reflect the intent of our 2003 boundary change action. Today's technical amendment makes no change to the substance of our October 7, 2003 final rule. Technical Amendments for California—Ozone (8-Hour Standard) Table in 40 CFR 81.305 With respect to the “California—Ozone (8-Hour Standard)” table in 40 CFR 81.305, we are making a number of technical amendments that stem from previous EPA rulemakings. All of the subject areas are located within the State of California. On April 30, 2004, at 69 FR 23858, we published a final rule announcing and promulgating designations, classifications, and boundaries for areas in the country with respect to the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) in accordance with the requirements of the Clean Air Act (CAA). In our April 30, 2004 final rule, we designated the Western Mojave Desert area as a moderate nonattainment area for the 1997 8-hour ozone National Ambient Air Quality Standard. See 69 FR 23858, at 23884-85 (April 30, 2004). Subsequently, on May 5, 2010, EPA published a final rule granting California's request for reclassification of several areas for the 1997 8-hour ozone standard. See 75 FR 24409 (May 5, 2010). The Western Mojave Desert was not among the areas that were the subject of EPA's May 5, 2010 final rule, but the changes made to the “California—Ozone (8-Hour Standard)” table to codify our May 5, 2010 final rule had the inadvertent effect of removing a portion of the definition of the Western Mojave Desert 8-hour ozone nonattainment area from the “California—Ozone (8-Hour Standard)” table. In today's action, EPA is making a technical amendment to re-insert the inadvertently removed portion of the definition of the Western Mojave Desert area into the “California—Ozone (8-Hour Standard)” table in 40 CFR 81.305. Second, in codifying the designations in EPA's April 30, 2004 final rule, we inadvertently indented the title of the 
                    ( print page 16448)
                    “Los Angeles-South Coast Air Basin, CA” in the “California—Ozone (8-Hour Standard)” table. Given the format of this table in the CFR, the inadvertent indentation of “Los Angeles-South Coast Air Basin, CA” in the “California—Ozone (8-Hour Standard)” table aligns the basin with the individual counties or portions thereof that comprise the basin and thus is potentially confusing. We are therefore making a technical amendment in today's action to properly format the title of the basin to show the proper relationship between the basin and the counties (or portions thereof) that comprise the basin. Third, in our April 30, 2004 final rule, we inadvertently failed to list the Indian Wells Valley area (which is that portion of Kern County that lies in hydrologic unit number 18090205) as “Unclassifiable/Attainment” in the California table of designations and classifications for the 8-hour ozone standard. We provided an explanation for distinguishing the Indian Wells Valley area from the rest of eastern Kern County in the background documentation for the April 30, 2004 final rule, but did not include the appropriate listing in the California table. See pages 3-22 to 3-23 in Chapter 3 (“Justifications in Support of EPA's 8-Hour Ozone Designations”) of EPA's report in support of the final designations entitled, “Technical Support for State and Tribal Air Quality Designations and Classifications” (April 2004). In today's action, we are making a technical amendment to properly list the Indian Wells Valley portion of eastern Kern County as an “Unclassifiable/Attainment” area for the 1997 8-hour ozone standard. Lastly, in EPA's April 30, 2004 final rule, EPA designated all of San Diego County in California as a nonattainment area for the 8-hour ozone standard but excluded from that nonattainment area a list of areas identified as La Posta Areas #1 and #2, Cuyapaipe Area, Manzanita Area, and Campo Areas #1 and #2. See 69 FR at 23887. We intended to designate the latter areas as “Unclassifiable/Attainment” and included our justification for their area designations and rationale for distinguishing them from the surrounding nonattainment area in the Technical Support Document for nationwide 8-hour ozone designations final rule. See pages 3-34 to 3-36 in Chapter 3 (“Justifications in Support of EPA's 8-Hour Ozone Designations”) of EPA's report in support of the final designations entitled, “Technical Support for State and Tribal Air Quality Designations and Classifications” (April 2004). However, the entries for these areas were inadvertently omitted from the table codifying designations and classifications for the 8-hour ozone standard within the State of California. In today's action, we are making a technical amendment to properly list the four tribal areas in eastern San Diego County as “Unclassifiable/Attainment” areas for the 1997 8-hour ozone standard. Today's technical amendments make no change to the substance of EPA's April 30, 2004 or May 5, 2010 final rules. List of Subjects in 40 CFR Part 81 Environmental protection

The map and attached set of coordinates are available at EPA's Region 9 Air Division office. The designated areas roughly approximate the boundaries of the reservations for these tribes, but their inclusion in this table is intended for CAA planning purposes only and is not intended to be a Federal determination of the exact boundaries of the reservations. Also, the specific listing of these tribes in this table does not confer, deny, or withdraw Federal recognition of any of the tribes so listed nor any of the tribes not listed.c

Nor does the specific listing of the Tribes in this table confer, deny, or withdraw Federal recognition of any of the Tribes listed or not listed.1
