SCHOOL BUS FLEETS FAQ

Is participation in Project Green Fleet REALLY free?

Yes! The generous support of Project Green Fleet’s funders will cover all retrofit equipment and installation costs for school buses.

What types of pollution control equipment are installed on school buses?

Project Green Fleet installs two different pieces of pollution-control equipment on school buses: a diesel oxidation catalyst (DOC) and a fuel-fired heater. These cost-effective technologies reduce diesel exhaust by more than 25%, and also reduce idling.

What about long-term maintenance, costs, and warranties?

After installation, the DOC requires no ongoing maintenance. The heaters require minimum maintenance during the summer months. Installation of pollution control equipment has no effect on a vehicle’s existing warranty.

What about impact on school bus performance?

According to the US EPA’s voluntary retrofit program, retrofit devices like oxidation catalysts have minimal impact on a vehicle’s performance and fuel economy.

Which school buses are eligible for retrofits?

Project Green Fleets targets school buses that are likely to have five or more years of expected operating life, and that lack the emission controls found on some of the newest school buses (generally those built before 2007).

Where can I find more information about pollution control equipment?

How can my school bus fleet participate in Project Green Fleet?

Fill out our online form and a staff member will be in contact with you to start the process. You can also contact Bjorn Olson at 612-334-3388 ext. 108 to sign up or ask questions.

How does participating in Project Green Fleet work?

Environmental Initiative has structured Project Green Fleet to be as easy as possible for fleet owners and operators. We coordinate the review of fleet information, installation of equipment and pay for installation and equipment costs. Read More »

OTHER DIESEL FLEETS FAQ

What kinds of diesel vehicles are eligible to participate?

Project Green Fleet installs pollution control equipment, idle reduction technologies and replaces older engines with new, cleaner running engines on a range of diesel fleets including, but not limited to:

  • Dump trucks
  • Cement mixers
  • Off-road construction equipment
  • Trains
  • Port facility fleets

What types of equipment are installed through Project Green Fleet?

Project Green Fleet installs are range of pollution control and idle reduction equipment on fleets of many sizes and times. Read More »

What does it cost to participate in Project Green Fleet?

The generous support of Project Green Fleet’s funders cover all equipment and installation costs for Diesel Oxidation Catalysts, Closed Crankcase Filtration Systems, Diesel Multistage Filtration Systems, Diesel Particulate Matter Filtration Systems and Auxiliary Power Units.  A percentage of the cost and installation is covered for equipment repowers and vehicle replacements. Project Funders »

Will the equipment impact my existing warranty?

Installation of pollution control equipment has no effect on a vehicle’s existing warranty. Certified engine repowers are done with manufacturer’s certified equipment and installers, so that the existing warranty remains intact.

Does the equipment have any impact on vehicle performance?

According to the U.S. Environmental Protection Agency’s voluntary retrofit program, oxidation catalysts and closed crankcase filtration devices have minimal impact on a diesel vehicle’s performance and fuel economy. Some of the other retrofit technologies have a minimal impact on performance

What kind of maintenance does pollution control equipment require?

Depending on the technology that is installed, there will be varying levels of maintenance required.  For example:

  • Diesel Oxidation Catalyst - No maintenance
  • Closed Crankcase Filtration System – Filter change, twice per year
  • Diesel Multi-Stage Filtration System – No maintenance, but must operate with a minimum exhaust temperature.
  • Diesel Particulate Filter – Requires periodic cleaning by a special machine, most maintenance intensive

Where can I find more information about pollution control or idle reduction equipment?

More information about retrofit equipment and projects is available on the following websites:
