Wood Burning Prohibited

Spare the Air Alert in effect through Friday, October 2.  Wood burning is banned.  Burn bans can occur year-round for wildfires. Smoke from wildfires is impacting air quality.  See our hourly air quality data for the most up-to-date information, as well as Press Releases@AirDistrict, and our Wildfire Safety Tips web page.  Sign up for Bay Area Air Alerts.  en Español

Agricultural Equipment

Upgrade or replace off-road diesel agricultural equipment.

FARMER zero-emission equipment demonstration program

Up to $1 million is available for projects that demonstrate mobile, zero-emission equipment in Bay Area agricultural operations and achieve significant reductions in greenhouse gas emissions, criteria pollutants, and toxic emissions.

The Air District is accepting applications for projects that demonstrate zero-emission mobile equipment greater than or equal to 25 horsepower. Eligible applicants are private sector parties, California-based public entities, and California-based non-profit organizations. Applications will be evaluated and scored competitively and are due to the Air District by 3 PM on April 15, 2020.

Funding is provided by the Funding Agricultural Reduction Measures for Emission Reductions (FARMER) Program which is part of California Climate Investments, a statewide program that puts billions of Cap-and-Trade dollars to work reducing greenhouse gas emissions, strengthening the economy, and improving public health and the environment – particularly in disadvantaged communities.

Status update: In response to the Shelter-in-Place orders that have been issued by Bay Area counties, many Air District employees have been transitioned to working remotely. We are tracking and monitoring the COVID-19 situation as it continues to evolve. At this time we are not proposing to extend the schedule or application deadline from what was in the original solicitation document. Please contact if your application is being delayed and will be unable to meet the deadline. Any future announcements will be posted here.

4/8/2020 Update: Submittal flexibility due to COVID-19 restrictions. Due to recent events, applicants should email copies of their application and mail the required hard copies of the original application to the Air District. Do not send hard copies through mail services that require a delivery signature to be received to prevent undeliverable mail and returned packages. In cases where email and hard copies are submitted, we will use the receipt of the email application as the official receipt date. In this case the hard copy must be postmarked by 3:00 pm on April 15, 2020. Email applications must be sent to Anthony Fournier at by 3:00 pm on April 15, 2020. Please use the email subject line text: Application Submittal Zero-Emission Mobile Agricultural Equipment Demonstration Program. The application submittal deadline has not been changed.

Off-road Agriculture Irrigation Pumps

Upgrade or replace off-road diesel agricultural pump engine(s) with funding from the Carl Moyer Program. This program aims to cut air pollution from heavy-duty diesel engines in California.

Project Types

The Air District is currently accepting applications for Agricultural Equipment projects. Funding is offered on a first-come, first-served basis until all funds have been spent. Applications must be complete to be considered for funding.

Funds are available for the following project types:

  • Engine replacement (repower) - replace an existing stationary or portable agricultural pump/engine with the cleanest-emissions engine available or with zero-emissions engine.
  • Engine retrofit - install an emission control device (stationary and portable equipment).
  • Equipment replacement - replace existing equipment with the cleanest available or zero-emissions equipment (mobile equipment - tractors, loaders, dozers, etc.).


The following agricultural equipment is generally eligible for funding; however, the fleet must be in compliance with applicable rules (see below) to apply:

Agricultural businesses that own a variety of equipment types are encouraged to apply for grants in other categories, especially if the application includes fueling or charging infrastructure.

Rules and Regulations

The Airborne Toxic Control Measure for Stationary Compression Ignition Engines (ATCM) (effective October 18, 2007) includes requirements for stationary and portable diesel-fueled engines used exclusively in agriculture. Typically, these engines are used to pump water or provide power for growing crops or raising livestock. All applicants interested in applying for stationary/ portable equipment must comply with the ATCM.

Please visit Agricultural Diesel Engines for additional regulatory information or contact Simon Margolis at 415-749-5121 for engine registration, and Guy Gimlen at 415-749-4734 for questions about the agricultural engine regulation.

How to Apply

  1. Determine your equipment’s eligibility for this program.
  2. Identify the project type for your equipment.
  3. Gather the required information about your current equipment and replacement equipment or engine.
  4. Work with an equipment dealer to source replacement equipment and engines.
  5. Apply for funding online.
