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--NO<INF>2</INF> 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--NO<INF>2</INF> (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--
NO<INF>2</INF> (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--NO<INF>2</INF> 
(1971 Annual Standard)'' table in 40 CFR 81.305 to accurately reflect 
the intent of our 2003 boundary change action.
---------------------------------------------------------------------------

    \1\ The table heading was recently revised to read 
``California--NO<INF>2</INF> (1971 Annual Standard)'' in a final 
rule published on February 17, 2012 at 77 FR 9532, at 9540, 
effective February 29, 2012. The table heading previously had been 
``California-NO<INF>2</INF>.''
---------------------------------------------------------------------------

    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

[[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 <greek-i>1 and <greek-i>2, Cuyapaipe 
Area, Manzanita Area, and Campo Areas <greek-i>1 and <greek-i>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.

  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.
