Background

The federal Clean Air Act (CAA or the Act) establishes planning requirements for those 

areas that routinely exceed the health-based National Ambient Air Quality Standards 

(NAAQS). These nonattainment areas must develop and implement a State 
2

Implementation Plan (SIP) that demonstrates how they will attain the standards by 

specified dates. Federal law holds each state responsible for implementing the 

provisions of the Act. 

In July 1997, the U.S. Environmental Protection Agency (U.S. EPA) promulgated a new 

8-hour NAAQS for ozone. U.S. EPA classified the San Joaquin Valley Air Basin as a 

“serious” nonattainment area with an attainment date of June 2013. The San Joaquin 

Valley Air Pollution Control District (District) developed an attainment plan with input 

from interested parties. In the 2007 Ozone Plan, the District’s analysis showed that the 

local, State, and federal controls already in place will be insufficient to allow the 

San Joaquin Valley to attain the ozone standard by the 2013 deadline. 

Consequently, the District adopted the 2007 Ozone Plan targeting a June 15, 2024 

“extreme” attainment date. The 2007 Ozone Plan includes new local emission control 

measures, as well as the emission reductions benefits of the proposed 2007 State 

Strategy which the Board will consider at its meeting scheduled for June 21-22, 2007. 

The 2007 Ozone Plan also relies on the use of new technology, as allowed under 

section 182(e)(5) the federal Clean Air Act, to provide the final increment of nitrogen 

oxide emission reductions. The District adopted the 2007 Ozone Plan on 

April 30, 2007. At that time, the District also requested a reclassification to “extreme” 

nonattainment of the federal ozone standard. 

The 2007 Ozone Plan establishes county-level on-road motor vehicle emission 

transportation conformity budgets for each milestone year, as well as for the attainment 

year. The emissions budgets in the 2007 Ozone Plan reflect the latest planning 

assumptions and were developed using EMFAC2007. ARB staff has updated the 

transportation conformity budgets to reflect revised Madera County vehicle activity data 

for all budget years, which were not available in time for publication in the 2007 Ozone 

Plan. In addition, the San Joaquin County 2008 transportation conformity budgets were 

updated to correct a data input error. Documentation on the proposed update is 

available on-line at http://www.arb.ca.gov/planning/sip/2007sip/2007sip.htm. 

In addition, ARB staff is proposing to update the emissions inventory to reflect a change 

in the calculation of pesticide emissions provided by the California Department of 

Pesticide Regulation (DPR) which was not available in time for the District’s plan 

publication and adoption. DPR staff has published a memorandum outlining revisions 

to the emission estimation calculations for ROG emissions from agricultural pesticide 

usage. These revised inventories reflect changes to the emission estimating 

methodology to include updated emission factors and the inclusion of an application 

use factor. 

 

The Clean Air Act requires that areas such as the San Joaquin Valley demonstrate 

“reasonable further progress” (RFP) toward attainment of the federal ozone standard 

and provide for contingency measures in the event that the required level of progress is 

not achieved. The 2007 Ozone plan demonstrates that these requirements will be met 

as a result of rules and regulations already in place. ARB staff concurs. However, the 
3

RFP demonstration included in the 2007 Ozone Plan does not include the impacts of 

the revised pesticide emissions, discussed previously. ARB staff has updated the RFP 

demonstration to include the revised pesticide emissions. ARB staff is proposing to 

submit this updated RFP demonstration to U.S. EPA for inclusion in California’s SIP for 

the San Joaquin Valley. 

Proposed Action

ARB staff has reviewed the 2007 Ozone Plan for the San Joaquin Valley and concluded 

that it meets applicable federal requirements. ARB staff has also concluded that the 

implementation of the 2007 Ozone Plan would reduce ozone levels throughout the 

San Joaquin Valley and result in attainment of the 8-hour ozone standard by 

June 2024. ARB staff is recommending that the Board approve the San Joaquin Valley 

2007 Ozone Plan, as well as the updated transportation conformity budgets, emissions 

inventory, and progress demonstration, as a revision to the California SIP. 

The 2007 Ozone Plan relies on emission reductions to be achieved from the proposed 

State Strategy for California’s 2007 SIP (State Strategy). ARB is scheduled to consider 

the State Strategy at its June 21-22, 2007 meeting, and thus at the June 14, 2007 

hearing ARB will be considering the 2007 Ozone Plan before the State Strategy has 

been approved. Therefore, final ARB approval of the 2007 Ozone Plan would be 

contingent upon ARB’s subsequent adoption of commitments, as part of the State 

Strategy, to achieve the emission reductions from State measures that are relied on in 

the 2007 Ozone Plan. 

ARB staff will present its recommendations to the Board at the meeting. Copies of a 

written Staff Report, which is expected to be available by May 24, 2007, may be 

obtained from the Board's Public Information Office, 1001 “I” Street, 1st Floor, 

Environmental Services Center, Sacramento, CA 95814, (916) 322-2990. The report 

may also be obtained from ARB’s internet site at 

http://www.arb.ca.gov/planning/sip/2007sip/2007sip.htm. 

Interested members of the public may also present comments orally or in writing at the 

meeting, and in writing or by email before the meeting. To be considered by the Board, 

written comments submissions not physically submitted at the meeting must be 

received no later than 12:00 noon, Wednesday, June 13, 2007, and addressed to the 

following: 

Postal mail: Clerk of the Board, Air Resources Board 

1001 I Street, Sacramento, California 95814 

Electronic submittal: http://www.arb.ca.gov/lispub/comm/bclist.php 

Facsimile submittal: (916) 322-3928

The Board requests, but does not require 30 copies of any written submission. Also, 

the ARB requests that written and email statements be filed at least 10 days prior to the 

meeting so that ARB staff and Board members have time to fully consider each 

comment. Further inquiries regarding this matter should be directed Mr. Jeff Lindberg, 

Air Pollution Specialist, (916) 322-2832, 1001 “I” Street, P.O. Box 2815, Sacramento, 

California 95812.
