Heavy Duty Trucks

The San Diego County Air Pollution Control District (APCD) administers several state-funded grant programs to cover
significant portions of the cost of replacing or repowering eligible equipment, which is then scrapped.


Grant applications are accepted for a limited time each year.


• When the grant program is opened, you can apply through the APCD Citizen Access online application system, or
for fleets of 10 or fewer trucks, you can apply to the streamlined Voucher Incentive Program (VIP) by contacting
a participating dealer.
• As the grant application window is limited, potential HEAVY DUTY TRUCK applicants may wish to gather legible
electronic copies of the needed documents in advance:


1. Anticipated costs of replacement engine or vehicle performing the same function as the existing unit


Written estimate (quote) from an equipment dealer documenting the cost of each piece of replacement equipment and—if applicable—retrofit device(s).


2. Certification level of proposed engine


CARB Engine Executive Order or EPA Engine Certificate of Conformity for replacement engine (from the equipment dealer)

3. Applicant certification of compliance with federal, state, and local air quality regulations


Grant Program Regulatory Compliance Statement, signed after the grant period officially opens.


4. Tax Forms


A completed current federal Form W-9 Taxpayer Identification Number and Certification, AND
• A completed current California Form 590 Withholding Exemption Certificate

5. Description of the existing vehicle and engine


Legible photographs of 1) manufacturer's tag found on the door jamb of the existing truck showing VIN and GVWR and 2) engine serial number tag and 3), the emission control label (showing EPA family name)


6. Proof of ownership of the vehicle for the past 24 months and that there is no lienholder on the title.

10. Proof of compliance with the CARB Truck and Bus Regulation

Finally, if you are planning to apply for a grant, please keep the following recommendations in mind:
• DO NOT PURCHASE NEW EQUIPMENT YET! New equipment funded by this program can only be ordered or
purchased once the contract is signed between the equipment owner and the APCD.
• KEEP EXISTING EQUIPMENT IN OPERATION! Existing equipment must be in operational condition. For heavyduty trucks, the vehicle must be in operation at a similar activity level to that listed in the application until the
equipment has been relinquished to an APCD-approved dismantler.
• STAY COMPLIANT! Equipment must remain compliant at all times with all applicable federal, state, or local
regulations, and all applicable regulatory advisories, without the assistance of any grant funding requested in
the application
