This grants program is to implement a portion of the Texas Emissions Reduction Plan (TERP), established in Chapter 386, Subchapter C of the Texas Health and Safety Code. 

The TCEQ has also adopted rules to implement this program under 30 Texas Administrative Code (TAC) Chapter 114, Subchapter K. The TCEQ has adopted the Texas Emissions Reduction Plan: Guidelines for Emissions Reduction Incentive Grants, RG-388 (guidelines), which contain the more specific standards governing this program.

The goals of the TERP are to:

  • assure that air in this state is safe to breathe and meets minimum federal standards established under the Federal Clean Air Act (42 U.S.C. Section 7407); 
  • develop multi-pollutant approaches to solving the state’s environmental problems;
  • adequately fund research and development that will make the state a leader in new technologies that can solve the state’s environmental problems while creating new business and industry in the state. 

To implement the TERP, the ERIG Program will provide grants for eligible activities to offset the incremental costs of projects that reduce emissions of NOX from high-emitting internal combustion engines in eligible areas.

RIG Project Categories for Eligible Vehicles and Equipment

Projects eligible for funding under this program are intended to reduce NOx emissions in eligible counties. The TCEQ may more narrowly define or limit the types of project categories for a particular funding period.

The types of project categories eligible under the FY17 ERIG funding period include (see funding announcement for complete details):

  • New Purchase or Lease:
    • To be eligible for funding, the engine on the new vehicle or piece of equipment must be certified to emit at least 25% less NOx than required under the current standard.
    • Certified means approved by EPA, the CARB, or otherwise accepted by the TCEQ.
  • Replacement:
    • The replacement of an eligible vehicle or piece of equipment with a newer vehicle or piece of equipment.
  • Repower:
    • The replacement (repower) of an existing engine in an eligible vehicle or piece of equipment with a new, rebuilt, or remanufactured engine.
    • The new engine must be certified to emit 25% less NOx than the engine being replaced.
    • Certified means approved by the EPA, the CARB, or otherwise accepted by the TCEQ.
  • Retrofit or Add-On of Emission-Reduction Technology:
    • The retrofit or add-on of emission-reduction technology to an existing engine in an eligible vehicle or piece of equipment.
    • Except for retrofits with certain dual-fuel conversion systems, the vehicle or equipment must be currently owned by the applicant and the retrofit or add-on systems must be certified or verified to emit at least 25% less NOx than the engine prior to the retrofit.

Other ERIG Project Categories

  • On-Vehicle Electrification and Idle Reduction Infrastructure:
    • The purchase and installation of equipment that enables a vehicle or equipment to use electric power to operate, while the vehicle or equipment is parked, the systems normally supplied power by the propulsion engine or another on-board internal combustion engine that emits NOx.
  • On-Site Electrification and Idle Reduction Infrastructure
  • Use of Qualifying Fuel
  • Rail Relocation and Improvement:
    • The relocation of rail lines to reduce the number of grade crossings, improvements at rail intersections, and other improvements that will directly result in the reduction of locomotive and/or vehicle engine idling at rail intersections.
    • Eligible rail intersections may include the intersection of two rail lines or an intersection of a highway or roadway and a rail line, commonly referred to as a highway-rail grade crossing.
    • The grant recipient must own or otherwise control the rail line, right-of-way, or the facility being improved.

  • Eligible Applicants:
    • Any person who operates or plans to operate on-road heavy-duty vehicles, non-road equipment, or stationary engines primarily in one or more of the nonattainment areas or other eligible counties of the state is potentially eligible for a grant. For infrastructure projects, persons owning or operating the infrastructure in an eligible county may also be eligible for funding. 
    • Eligible applicants include individuals, corporations, organizations, governments or governmental subdivisions or agencies, business trusts, partnerships, associations, or any other legal entity.
    • Eligible applicants must also have the legal authority to dispose of the vehicle being replaced in accordance with the requirements outlined in Section 2.4 of the RFGA.
  • Eligible Counties:
  • Eligible Vehicles and Equipment:
    • The types of vehicles and equipment eligible under the FY17 ERIG funding period include: 
      • Heavy-Duty On-Road Vehicles: must have a gross vehicle weight rating (GVWR) of 8,500 pounds or more and be certified by the Environmental Protection Agency (EPA) to the heavy-duty vehicle federal emission standard. 
      • Heavy-Duty Non-Road Equipment, Stationary Equipment, and Marine Vessels:: engines must have horsepower (hp) rating of 25 or greater.
      • Locomotives: must have engines greater than or equal to 1,006 hp. A switcher locomotive in which the total horsepower of the replacement unit is less than 1,006 will be considered a non-road project, unless otherwise specified by the TCEQ.


  • Businesses or other entities in which a TCEQ employee, spouse, or family member of a TCEQ employee has a direct or indirect interest, financial or otherwise, may be prohibited from receiving a grant, depending upon the nature of the interest.
  • Vehicles and equipment used primarily for competition or recreational purposes are not eligible for funding under any of the ERIG project categories.
