Funding, Finance, and Regulations Working Group

What is the CMAQ Program?

The Congestion Mitigation and Air Quality (CMAQ) program provides a flexible funding source for State and local governments to fund transportation projects and programs that reduce mobile source emissions to help meet the requirements of the Clean Air Act. Funding is available to reduce congestion and improve air quality in areas that do not meet the National Ambient Air Quality Standards for ozone, carbon monoxide, or particulate matter ("nonattainment areas") and for former nonattainment areas that are now in compliance ("maintenance areas") (See 23 U.S.C. 149 and 42 U.S.C. 7407).

Since its inception in 1992, the CMAQ program has provided more than $30 billion to fund over 30,000 transportation-related emission reduction projects for State departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other sponsors across the country.

Projects funded must be included in the MPO's current transportation plan and transportation improvement program (TIP) or the current State transportation improvement program (STIP) in areas without an MPO.

What is the DERA Program?

The Diesel Emissions Reduction Act (DERA) program makes funds available for diesel emissions reduction, including rebuilding diesel-powered vehicle engines to more stringent emission standards or installing emission reduction systems (See 42 U.S.C 16132). Seventy percent of the DERA appropriation is used for national competitive grants and rebates that use certified diesel emission reduction technologies. Thirty percent of the appropriation is allocated to States to fund programs for clean diesel projects. Base funding is distributed to States and territories using a formula based on overall participation. Additional incentive funding is available to States and territories that provide matching funds.

Since the program was funded in 2008 through 2013, DERA awarded $520 million. Congress authorized up to $100 million in awards annually for FY2012 through FY2016, and the Environmental Protection Agency (EPA) is awarding up to $40 million in grant funding in 2018.

CMAQ and DERA-eligible Truck Idle Reduction

  • Verified Onboard Idle Reduction Technologies
  • Truck Stop Electrification (TSE) and Electrified Parking Spaces (EPS)

Idle Reduction Technology (IRT)

The term "idle reduction technology" refers to devices that allow engine operators to refrain from long-duration idling of the main propulsion engine by using an alternative source of power.

An IRT device reduces unnecessary main engine idling of the vehicle or equipment and is generally one of the following:

  1. Is installed on a vehicle (e.g., truck, bus, truck, locomotive, automobile, etc.) or at a location where vehicles park, or
  2. Provides services (e.g., heat, air conditioning, and/or electricity) to the vehicle or equipment (e.g., transport refrigeration unit) that would otherwise require the operation of the main engine.

Onboard IRTS for Trucks

Verified onboard idle reduction technologies are systems installed on the vehicle to reduce unnecessary main engine idling and include:

  • Auxiliary Power Unit and Generator Set (APU/GS): An APU/GS device contains an EPA emission-certified engine that supplies cooling, heating, and electrical power.
  • Fuel Operated Heater (FOH): A FOH is a small, lightweight heater that burns fuel from the main engine fuel supply or a separate fuel reserve.
  • Battery Air Conditioning System (BAC): A BAC system uses batteries to power an independent electric cooling and/or heating system. Typically, a BAC system integrates a FOH to supply heating.
  • Thermal Storage System (TSS): A TSS collects heat energy as a truck is driven, and uses it to provide air conditioning.

If CMAQ funding is used for an on-board IRT (i.e. auxiliary power units, direct fired heaters, etc.) the vehicle must travel within, or in proximity to and primarily benefiting, a nonattainment or maintenance area.

Truck Stop Electrification and Electrified Parking Spaces

Truck Stop Electrification (TSE) and Electrified Parking Spaces (EPS) refers to a technology that uses electricity-powered components to provide the operator with climate control and auxiliary power without having to idle the main engine. This can be on-board equipment (e.g., power inverters, plugs), off-board equipment (e.g., electrified parking spaces or systems that directly provide heating, cooling or other needs), or a combination of the two.

The EPS system provides off-board electrical power to operate the following:

  • Independent heating, cooling, and electrical power system.
  • Truck-integrated heating and cooling system.
  • Plug-in refrigeration system that would otherwise be powered by an engine.

The CMAQ funding for TSE is limited to capital costs (i.e. deployment of TSE infrastructure). Operating assistance for TSE should not be funded under the CMAQ program since TSE projects generate their own revenue stream and therefore should be able to cover all operating expenses from the accumulated revenue. Commercial TSE cannot be located within rest areas of the Interstate right-of-way (ROW) (See 23 U.S.C. 111 and CMAQ Interim Program Guidance at https://www.fhwa.dot.gov/environment/air_quality/cmaq/policy_and_guidance/2013_guidance/index.cfm#ftnref47).
