SUBJECT: PUBLIC WORKSHOP ON THE PROPOSED REGULATION FOR STATE 

IMPLEMENTATION PLAN CREDIT FROM MOBILE AGRICULTURAL 

EQUIPMENT 

The California Air Resources Board (ARB or Board) invites you to participate in the third 

public workshop to discuss draft regulatory language for the Proposed Regulation for 

State Implementation Plan Credit from Mobile Agricultural Equipment. This regulation 

was previously referred to as the In-Use Off-Road Mobile Agricultural Equipment 

Regulation or Mobile Ag Regulation.

The date, time and locations for the workshop are as follows:

San Joaquin Valley (will also be webcast):

Date: Tuesday, July 9, 2013

Time: 1:30 P.M. to 3:30 P.M. 

Location: San Joaquin Valley Air Pollution

Background

In 2007, the San Joaquin Valley Air Pollution Control District (SJVAPCD) developed a 

State Implementation Plan (SIP) to meet the 0.08 parts per million (ppm) 8-hour ozone 

standard by 2023. The 2007 SIP, which was approved by the U.S. Environmental 

Protection Agency (U.S. EPA) in December 2011, contains a 2013 commitment by ARB 

to propose a regulation for mobile agricultural equipment in the San Joaquin Valley, 

which is comprised of the counties within the SJVAPCD, including San Joaquin, 

Stanislaus, Merced, Madera, Fresno, Tulare, Kings counties, as well as the western 

portion of Kern County. Specifically, the approved SIP includes a goal to achieve

emissions reductions of 5-10 tons per day of oxides of nitrogen in San Joaquin Valley 

by 2017 in order to accelerate air quality progress. 

SJVAPCD, ARB, U.S. Department of Agriculture Natural Resources Conservation 

Service, and U.S. EPA signed a Statement of Principles in 2010 to work collaboratively 

to develop a mechanism to provide SIP credit for investments made in the San Joaquin 

Valley through local, state and federal incentive funds and by the agriculture industry to 

clean up mobile agricultural equipment. ARB’s regulatory action is the outcome of this 

Statement of Principles. 

Proposed Regulation

The Proposed Regulation for State Implementation Plan Credit from Mobile Agricultural 

Equipment would provide an administrative mechanism to ensure that incentive-funded 

mobile agricultural equipment projects implemented using Carl Moyer Program 

guidelines and administered by SJVAPCD result in emission reductions that are eligible 

for SIP credit. This proposed regulation would also allow an opt-in for any other air 

district in California that complies with the requirements of the proposed regulation to 

have mobile agricultural equipment emission reductions that result from incentive 

programs that follow the Carl Moyer Program guidelines be eligible to be considered for 

SIP credit. To meet U.S. EPA criteria for SIP creditability of incentive funded projects, 

the emission reductions must be surplus, quantifiable, enforceable, and permanent. 

The proposed regulation is intended to complement SJVAPCD’s Rule 9610 which 

provides administrative requirements on local, state, and federal voluntary incentive 

programs in the San Joaquin Valley to ensure that emission reductions are eligible to 

receive SIP credit.

ARB’s proposed regulation requires that mobile agricultural equipment incentive 

projects follow the Carl Moyer Program Guidelines. To ensure accountability, ongoing 

program reviews and audits by the air district will be required to verify project data, 

application information, emission reductions, destruction verification, and retention of 

application, inspection, destruction, and other project-related documentation consistent 

with the Carl Moyer Program Guidelines. This proposed regulation will be presented for

Board consideration in October 2013.

Future Actions to Address New Air Quality Standards

During ARB and the SJVAPCD implementation of the 2007 8-hour ozone SIP, U.S. EPA 

revised the 8-hour ozone standard in 2008, lowering the level to 0.075 ppm. A new SIP 

for the revised 8-hour ozone standard will be developed for submittal to U.S. EPA in 

2015. This SIP will address additional reductions needed in the San Joaquin Valley to

attain the more stringent 8-hour ozone standard, with an attainment deadline of 2032. 

The new SIP will include a comprehensive strategy applying to many types of sources,

including strategies that rely on the future availability of the cleanest technologies for

mobile agricultural equipment operating in the San Joaquin Valley. ARB staff is 

planning to hold a separate public workshop in fall 2013 to discuss possible strategies 

for inclusion in the 2015 SIP, with the goal of securing additional reductions from mobile 

agricultural equipment in the San Joaquin Valley by the 2032 attainment deadline. 

Workshop Topics for Discussion

 California’s air quality goals and the need for emission reductions from the 

agricultural sector of the San Joaquin Valley

 Discuss the Proposed Regulation for State Implementation Plan Credit from 

Mobile Agricultural Equipment 

 Next steps

 Open Discussion

Staff’s presentation will be followed by an opportunity for public comment and 

discussion. We welcome and encourage your participation in this effort.

Staff’s presentation and all associated documents will be posted in advance of the 

workshop on ARB’s website at: http://www.arb.ca.gov/ag/agtractor/agtractor.htm.
