SLO County APCD has been operating our Grant Program since 1997. In that time, we have infused over $20.3 million dollars into our local economy to help businesses modernize their equipment and comply early with State emission regulation. These dollars have funded the reduction of over 2,700 tons of smog forming pollutants.

We are proud to partner with local businesses and individuals to help them replace their dirty on-road, off-road and agricultural vehicles & equipment with new, cleaner and equipment through our Grant Program. Click here to see just a few of the individuals we have worked with in securing grant funding to clean up their fleets!

Grant News

On January 25, 2017 the APCD Board approved additional funding for the Engine Emission Reduction Incentive Program (EERIP) using a total of $454,102 from the State Carl Moyer Program and local AB923 funds. Grant projects funded with these monies provide the APCD with the opportunity to reduce emissions and help local companies significantly reduce their cost of upgrading to new, clean emitting equipment prior to regulation requirements. EERIP will fund the following:

  1. Off-Road Equipment Replacement Program (ERP): Replacements of construction equipment and tractors;
  2. On-Road Fleet Modernization Program (Fleet Mod): Replacements of on-road heavy-duty trucks; and,
  3. Off-Road Repowers, Retrofits and Electrifications of off-road equipment such as irrigation engines, tractors, and mobile construction equipment.

The APCD continues to partner with a local network of truck and equipment dealers and scrap yards to help local businesses secure EERIP funding for their emission reduction projects. Some of the EERIP specifics include:

  • Funds are awarded on a first-come, first-served basis based on when APCD deems an application is complete;
  • Provides up to 65% of ERP projects or repower / electrification / retrofit cost of the off-road equipment listed above;
  • Provides up to $60,000 per vehicle for on-road trucks;
  • Provides up to $150,000 per applicant, per calendar year;
  • Replacement trucks and equipment for Fleet Mod or ERP must be purchased from an APCD approved dealership;
  • No orders, purchases or any work associated with a project can occur until APCD grant agreement is signed by all parties; and,
  • Applications are available on the APCD website or call 805-781-5912.
