Eligible areas

Review documents to ensure eligibility

Step 2 Determine your emissions

Find the federal emission standard for the engine of the vehicles or equipment being replaced by using the table applicable to your equipment type:

For engine models 2003 and later, you will need to provide the Engine Family Code to verify the federal emission standard. You may need to look up the Engine Family Code if you cannot find it on your engine:

Step 3 Estimate your maximum grant amount

Grant recipients may be eligible for up to 80% of the eligible costs associated with the purchase, lease, replacement, or repower of the vehicles or equipment. Grant amounts cannot exceed the maximum amounts listed in the Maximum Eligible Grant Amount Tables.

Note: The Maximum Eligible Grant Amount Tables have been updated to define the fuel types under natural gas.
