Question 1: Is an idle reduction policy required?

Successful applicants (school bus projects only) shall implement a fleet-wide idle reduction policy. Unnecessary vehicle idling pollutes the air, wastes fuel, and causes excess engine wear. Reducing idling saves money for fleets. Idling should be limited to the engine manufacturer's recommendation (generally no more than five minutes). Applicants should specify the policy to be implemented including (but not limited to) idling time limits, idling exceptions, expected fuel savings, etc.

Question 2: What is idling?

An idling vehicle is one whose engine is running when it is parked or not in use. Common reasons for engine idling are:

  • doing an errand
  • warming up the vehicle
  • waiting for someone
  • personal comfort
  • listening to the radio
  • parking illegally
  • convenience

These examples are NOT considered idling:

  • regular stopping in traffic
  • stopping at loading/unloading zones

Question 3: What are common anti-idling strategies?

  • Reduce early morning idling time to limit exhaust buildup from diesel vehicles.
  • Designate an indoor area for drivers to wait if they arrive early.
  • Position diesel vehicles away from building air intake vents so pollution does not accumulate inside the building.
  • Change diesel vehicle circuit configuration to run the lights and heating/cooling off the battery.

Question 4: How can we participate in the National Idle Reduction Campaign?

Information on how to participate can be found under the "Idle Reduction" tab here:

Question 5: Is replacing gasoline powered vehicles with new diesel powered vehicles eligible?

No, only diesel transit buses, diesel school buses, and Class 5-8 heavy-duty diesel trucks are eligible for funding. The replacement of gasoline powered vehicles is not allowable under the current grant announcement (FY17). However, the replacement of diesel vehicles with newer vehicles that operate on diesel or alternative fuels is allowable.

Question 6: How much does DEQ match to reimburse if a diesel vehicle is replaced with a new diesel or alternative fuel vehicle?

DEQ's match to reimburse is up to 25% for vehicles powered by a 2017 or newer engine certified to EPA emission standards, up to 35% for vehicles powered by a 2017 or newer engine certified to meet CARB's Optional Low-NOx Standards, and up to 45% for vehicles powered by an all-electric engine.

Question 7: What constitutes the "scrappage" of a vehicle after it is replaced? Are we allowed to sell it?

To be able to apply for this funding opportunity for replacement of a vehicle, the vehicle being replaced must be scrapped or rendered permanently disabled within ninety (90) days of being replaced. Proof of scrappage must be provided to DEQ. The replacement vehicle must perform the same function and be of the same type and similar gross vehicle weight rating or horsepower as the vehicle that is being replaced.

Cutting a three-inch by three-inch hole in the engine block (the part of the engine containing the cylinders) and disabling the chassis by cutting through the frame/frame rails on each side at a point located between the front and rear axles is the preferred scrapping method. Other acceptable scrappage methods may be considered and will require prior EPA approval. Evidence of appropriate disposal, including engine serial number and vehicle identification number (VIN), is required in a final assistance agreement report submitted to EPA.

Vehicle components that are not part of the engine or chassis may be salvaged from the unit being replaced (e.g., plow blades, shovels, seats, tires, etc.). If scrapped or salvaged vehicles/parts are to be sold, program income requirements apply and must be accounted for in the project.
