Cal. Health & Safety Code § 43021.5

In order to minimize the impact of the energy transition on the supply chains in the critical agricultural sector and ensure that disadvantaged communities equitably share in the benefits of and investments in emission reductions, the state board shall establish the Small Agricultural Truck Fleet Assistance Program, or use an existing program, to provide dedicated technical assistance to owner-operators or owners of small fleets to support the transition to cleaner emission-compliant trucks, giving priority for near-zero-emission or zero-emission trucks as feasible.
