NEW! SCAQMD is no longer accepting applications for
Eligible Surplus Off-Road Opt-In for NOx (SOON) Projects under
Program Announcement #2017-06
Please revisit this webpage in early 2018 for updated information on Carl Moyer and SOON funding opportunities.
What is the SOON Program?
Title 13, Section 2449 of the California Code of Regulation (CCR), "Regulation for In-Use Off-Road Diesel-Fueled Fleets (Off-Road Regulation) " was adopted by the California Air Resources Board (CARB) in July 2007 and requires off-road diesel vehicle fleets to achieve NOx and PM2.5 reductions by meeting NOx and PM fleet average standards.
A provision of the Off-Road Regulation (Title 13, CCR, Section 2449.2) allows air districts to opt-in and require the largest fleets to apply for funds to meet more stringent NOx targets. As a result, the South Coast Air Quality Management District’s Surplus Off-Road Opt-In for NOx (SOON) Program was developed in 2008. The SOON Program provides funding assistance to large fleets for the purchase of commercially-available low-emission heavy-duty engines to achieve near-term reduction of NOx emissions from in-use off-road diesel vehicles. NOx reductions achieved must be surplus to those required from the Off-Road Regulation.
Fleets that participate in the SOON Program can apply for funding for NOx exhaust retrofits, repowers or equipment replacements.
Who is Eligible for Funding?
- All large fleets with a total statewide equipment horsepower over 20,000 hp must apply for funding.
- Fleets below 20,000 hp may voluntarily participate in this program.
How Do I Apply for SOON Funding?
Fleets subjected to SOON Program requirements and provisions are required to apply through the Carl Moyer Online Application portal. SCAQMD is currently not accepting any online applications for SOON projects - please revisit this site in early 2018 for SOON funding information and how to apply.
