California Plan Revision: Redesignation ofAir QualityControl 

### Regions
AGENCY: Environmental Protection Agency (EPA). 

### ACTION:Final rulemaking.

SUMMARY- The EPA takes final action to 

### approve the redesignation ofseven Air Quality Control Regions (AQCR's) and the designation oftwo additional AQCR's in California, as requested by the California Air Resources Board (ARB). The intended effect ofthese designations and redesignations is to promote more efficient and effective air quality management. EFFECTIVE DATE: February 17, 1981,
ADDRESS: A copy of the redesignation 

### request is located at: The Office ofthe Federal Register, 1100 "L"StreetNW., Room 8401, Washington, D.C. 20408.
FOR FURTHER INFORMATION CONTACT. 

### Louise P. Giersch, Director, Air and Hazardous Materials Division, EPA Region IX, 215Fremont Street, San Francisco, California 94105, Attn: Douglas Grano, (415) 556-2938. SUPPLEMENTARY INFORMATION: 

### Background

Under Section 107of the Clean Air Act, as amended, 11 AQCR's in California were designated by the Administrator.Boundaries ofthese AQCR's are described in the following sections of40 CFR Part81:

Sec. 81.17 Metropolitan los Angeles AQCR. 81.21 The San Francisco Bay Area Intrastate AQCR.

_ 81.159 Great Basin Valley intrastateAQCR. 81.160 North Central Coast Intrastate AQCR. 81.161 North Coast Intrastate AQCR. 81.162 Northeast Plateau Intrastate AQCR. 81.163 Sacramento Valley intrastate AQCR. 81.164 SanDiego Intrastate AQCR. 

### 81.165 San Joaquln ValleyIntrastate AQCR;
81.166 South Central CoastIntrastate AQCR.

81.167 Southeast Desert IntrastateAQOCR.



### Altogether, the AQCR's listed above include the entire state. Atthe time they became effective theirboundaries coincided with those ofthe California AirBasins as defined in the California Administrative Code. Since then the boundaries ofseveral air basins have been changed, and additional air basins have been created.

Changes that have been made by the ARB to the original air basins are as follows:

1. Oh May 18, 1971, northeastern Solano County was transferred from the San Francisco Bay Area Air Basin to the Sacramento Valley AirBasin.

2. On May 18, 1971, northern Sonoma County was transferred from the San Francisco BayArea Air Basin to the North Coast AirBasin.

3. OnJuly 21, 1971, western Siskiyou County was transferred from the North CoastAirBasin to the Northeast Plateau AirBasin.

4. On September 15, 1971, a portion of Kern Countyin the vicinity ofTehachapi

was transferred from the San Joaquin ValleyAirBasin to the Southeast Desert Air Basin.

5, On June 21, 1974, the Mountain Counties AirBasin was created from five counties (Plumas, Sierra, Nevada, Placer, and ElDorado) ofthe Sacramento Valley AirBasin and four counties (Amador, Calaveras, Tuolumne, and Mariposa) of the San Joaquin ValleyAir Basin.

6. On July 19,1974, the Lake County Air Basin,consisting ofall ofLake County (previously in theNorth Coast AirBasin), was created.

7. On December 30,1975, the Lake Tahoe AirBasin, comprising theLake Tahoe watershed in Placer and El Dorado Counties, was created frompart of the Mountain Counties Air Basin.

8. On August 31, 1976, Ventura County and southern Santa Barbara County were transferred from the South Coast Air Basin (Metropolitan Los Angeles AQCR) to the South Central Coast Air Basin.

9. OnJuly 1, 1977, eastern SanDiego County was transferred from the Southeast Desert AirBasin to the San Diego AirBasin.

As a result ofthese changes, there are
now 14 State-designated air basins in California, ofwhich two (North Central Coast and Great Basin Valleys) remain

as originally established. Ofthe remaining 12, three (Mountain Counties, Lake County, and Lake Tahoe) are new and nine have been changed since their original establishment.
TheRedesignation

On September 11, 1978, the Executive Officer of the ARB requested the EPA's approval ofseven redesignated and two additionally designated (new)AQCR's in California.

The seven redesignated AQCR's in the State's proposal are as follows:

1. Northeast Plateau 2. North Coast 3. Sacramento Valley 4. San Francisco Bay Area 5. San Joaquin Valley 6. Southeast Desert 7. SanDiego The two new AQCR's proposed by the State are as follows:

1. Lake County 2. Mountain Counties Two AQCR's in the State's proposal

are unchanged from their original designation and thus remain as now designated, as follows:

1.Great BasinValley 2. North Central Coast Two AQCR's continue to differ from the corresponding airbasins. Although the boundary between the South Central Coast and the South Coast Air Basins

was changed in 1976 (see change #8 underBackground, above), redesignation ofthe South Central Coast and theMetropolitan Los Angeles (South Coast) AQCR's is notbeing proposed at this time.

Another discrepancy between the air basins designated by theARB and their proposed redesignation ofAQCR's is the exclusion oftheLake Tahoe basin from the proposed Mountain Counties AQCR without a separate proposal ofLake Tahoe as an AQCR, although thebasin

was designated as an airbasin by the ARB in 1975 (see change #7 under Background, above).

Asindicated inthe ARB's StaffReport No. 78-14-3, the LakeTahoe basin presents unique regulatory and administrative problems because the airshed is shared by California and Nevada. In view ofthe possibility of designation oftheLake Tahoe basin as
an Interstate AQCR,intrastate designation was notproposed by the ARB.



### Under section 107(b)(2) ofthe Clean AirAct, as amended, theLake Tahoe situation isbeing remedied bythe EPA's designation of thebasin as an intrastate AQCR.This action, which the EPAnow takes, does not preclude any future designation of the Lake Tahoe area by California or byCalifornia and Nevada. Effects of Redesignation
The redesignation AQCR's in California should begin to eliminate much of theconfusion and misunderstanding which have occurred because of the differences between the State airbasins and the Federal AQCR's. With this approval bythe EPA ofthe redesignation (including designation of the Lake Tahoe AQCR), the geographic applicability oflocal, State, and Federal regulations will be

more uniform and thus more easily understood. I I 

### 3883

### 3884 Federal Register / Vol. 46, No. 11 / Friday, January 16, 1981 1 Rules and Regulations

As a result ofthese designations and redesignations ofAQCRs, many changes are being made to the Codeof FederalRegulations (CFR). InPart 81, most ofthe California AQCR descriptions are being revised, and newly designated AQCR's are being added. As a consequence ofthosePart 81 changes, numerous revisions are being made in Part 52, Subpart F (§§52.220-52.280).

Many ofthe changes in Part 52 are of

a classificatory nature, where either (1) certain APCD's are being reclassified as to the AQCR in which they arelocated,

or (2) references to AQCR's arebeing removed from the CFR; §§52.231, 52.233, 52.234, 52.236, 52.240, 52.269, 52.271, 52.272, 52.273, 52.275, and 52.280 are so revised.

In other sections (§§ 52.246, 52.252, 52.253, 52.254, and 52.255), which contain Federal requirements, the AQCR's to which the regulations apply are being

. 

### defined "as ofJuly 1,1979" ("old" AQCR's), so that the Federal requirements in affected areas are not changed.



### OnApril 20, 1979 C44 FR 23544) the EPA published a Notice ofProposed Rulemaking, proposing to approve the redesignation and to designate on its

own the LakeTahoe AQCR, and inviting public comments. One comment,a letter fromthe Nevada Department ofConservation and Nautral Resources, Division of Environmental Protection, was received. That letter objected to the EPA's proposed designation ofthe California portion oftheLake Tahoe Basin as-an intrastate AQCR and advocated designation ofan interstate AQCR to -include the entire Basin, in California

and Nevada.

As notedin the Notice ofProposed Rulemaking, the ARB excluded the Lake Tahoe Basin from theMountain' Counties AQCRbut did notpropose the designation ofa Lake Tahoe Intrastate AQCR, norhive thetwo states proposed an-interstate AQCR forLake Tahoe. As provided in section 107(b)(2) ofthe Clean AirAct, as amended, "the portion ofsuch State which is notpart of any such designated region shall be an air quality controlregion.. '

This action by the EPA does not preclude the future designation ofthe Lake Tahoe Basin as an interstate AQCR. The EPAwould publish a proposal to that effect as soon as the States ofCalifornia and Nevada jointly request such a redesignation.

The EPA is approving this redesignation because itmeets the requirements ofsection 107(e) ofthe Clean AirAct, as amended, which requires that theredesignation be for purposes ofimproved air quality management.

The EPA has determined that this action is "specialized" and therefore not subject to the procedural requirements ofExecutive Order 12044. (Secs. 107, 110, 310(a), Clean AirAct, as amended (42 U.S.C. 7407,7410, and 7601(a))
