Emissions Reduction Incentive Grants (ERIG) Program

A Program of the Texas Emissions Reduction Plan (TERP)

Welcome to the TERP ERIG homepage. The goal of the ERIG program is to provide grant funding opportunities to offset the cost of projects that reduce emissions of nitrogen oxide (NOx) from high-emitting mobile diesel sources in eligible counties. On the ERIG Home tab you will find useful links related to the ERIG program. Navigate the other tabs to review eligibility and project categories pertaining to the program and instructions on how to apply.
The latest application period has ended. Applications may no longer be submitted for funding consideration.

Download the Grant Estimator and Technical Supplement for your project type. The Technical Supplement provides step-by-step instructions for completing the grant amount calculations. Each of the pages of the Grant Estimator is on an individual Excel worksheet within the Workbook. Use the tabs located at the bottom of the worksheet to access each page.

In order to use the Excel Grant Estimator, please follow these directions:

  • Download the Grant Estimator for your project type and save to your computer.
  • Open the Estimator saved to your computer.
  • Start entering activity data on Activity Tab 1.
  • Enter the requested information using the Technical Supplement as a guide. Call TCEQ if your replacement vehicle or equipment is powered by an alternative fuel.
  • Repeat steps 3 & 4 for each activity included in the application.
  • Arrive at your estimated grant amount.

How Do I Know if I Am Eligible for a Grant?

This section lists general information about eligible applicants, eligible counties, and the types of projects that may be eligible for grant funding. For complete information on the types of projects and expenses that may be eligible for a grant, refer to the Request for Grant Applications (RFGA):


Read the RFGA

General Information about eligible applicants, eligible counties, and the types of projects that may be funded is provided below:

  • 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 4.0 of the RFGA.

The counties in which projects may be eligible for funding include the state’s air quality nonattainment areas and other affected counties.

  • Non-Road Equipment: the manufacture year of the engine installed on the replacement equipment must be 2015 or newer.
  • The replacement vehicle or equipment must be certified to emit at least 25% less NOx than the vehicle or equipment being replaced. Certified means approved by the EPA, the CARB, or otherwise accepted by the TCEQ.
  • The applicant must own the vehicle at the time of application, and must have continuously owned, commercially financed, or leased the vehicle and have been listed as the owner on the title or the lessee on the lease agreement for the two years immediately preceding the application date.
  • Unless the vocational type of the vehicle is exempt from inspection and registration requirements, the vehicle must currently be registered for operation in Texas and must have been continuously inspected and registered in Texas for the two years immediately preceding the application date.
  • The vehicle or equipment must have been used in its primary function in the routine operations of the applicant in Texas for the two years immediately preceding the application date and be capable of performing its primary function for the duration of the project Activity Life.

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.

Manufacturers of Dual-Fuel Conversion Systems

The TCEQ announces the availability of procedures for a manufacturer of a dual-fuel (natural gas + diesel) conversion system for the retrofit of an existing heavy-duty on-road or non-road engine to request a determination by the TCEQ of the emissions reduction factors that may be used in considering an application for grant funding under the ERIG program.

Dual-Fuel Conversions

Retrofit activities to convert a heavy-duty on-road or non-road engine to operate under a dual-fuel configuration that uses natural gas and diesel fuel may be considered using a different minimum standard for the reduction in NOx than is required for other types of projects. The minimum standards will be established in each RFGA.pdf

How to Request a Determination of Emission Reduction Factors:

In order to determine a NOx emissions percentage reduction factor to use in the application for a dual-fuel retrofit project, manufacturers may submit emissions test data to the TCEQ to evaluate the emissions reductions that will be accepted through the use of a particular system. The following notice and procedures documents provide information for manufacturers to complete this process.

Dual-Fuel Conversion Systems Evaluated by the TCEQ:

The dual-fuel conversion systems that have been evaluated by the TCEQ and assigned a NOx emissions percentage reduction factor are listed below. Copies of the letters sent to the manufacturers assigning a percentage reduction factor for each system evaluated may be obtained from the links listed below.
