California Air Resources Board Approves FARMER Funding Program

On March 23, 2018 at the California Air Resources Board (CARB) meeting  in Riverside, the Funding Agriculture Replacement Measure for Emission Reductions (FARMER) program was approved.  The FARMER funding will be used to provide $135,000,000 in funding statewide to provide incentives for the replacement of: agricultural harvesting equipment, heavy-duty trucks, agricultural pump engines, tractors and other equipment used in agricultural operations.

The majority of the FARMER funding has been allocated to the San Joaquin Valley ($108,000,000) and to sixteen other specific air districts based on the each districts reported emission levels from farm equipment.  Eighteen air quality districts, including the  Mendocino County Air Quality Management District, were combined into the “districts with less than 1% of statewide emissions from farm equipment” category and have been allocated $5,572,100. Funding is scheduled to be made available from 2019-2021.

Mendocino County does not have degraded air quality, but farmers, ranchers and businesses in the county are still mandated to comply with statewide CARB regulations.  This is why Mendocino County Farm Bureau (MCFB) Executive Director, Devon Jones, attended the March 23rd hearing to testify on behalf of the 1% counties and to encourage the CARB members and staff to expedite the funding distribution process for the 1% counties.

The FARMER monies can help to offset the cost of replacing qualified agricultural engines prior to a compliance mandate. For example, Tier 0 or Tier 1 stationary diesel irrigation engines that are registered with the Mendocino Air Quality Management District will need to be replaced by 2020-2021.  FARMER funding can help to offset the $25,000+ cost of engine replacement prior to 2020.

MCFB will continue to engage with the Mendocino County Air Quality Management District,  CARB and California Farm Bureau Federation in order to provide information to our members on how to apply for the FARMER funding. For more information, please contact MCFB at (707) 462-6664.
