Applicants


 

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.


 

Reports and Information


 


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

This section lists general information about eligible applicants, counties, vehicles and equipment, and project categories under the Emissions Reduction Incentive Grants (ERIG) Program. For complete information applicants should refer to the latest Request for Grant Applications (RFGA) and the Guidelines for Emissions Reduction Incentive Grants.

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 eligible counties 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, school districts, 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:


  • The counties in which projects may be eligible for funding include the state’s air quality nonattainment areas and other affected counties:
Bastrop Bexar Brazoria Caldwell Chambers Collin
Comal Dallas Denton El Paso Ellis Fort Bend
Galveston Gregg Guadalupe Hardin Harris Harrison
Hays Henderson Hood Hunt Jefferson Johnson
Kaufman Liberty Montgomery Nueces Orange Parker
Rockwall Rusk San Patricio Smith Tarrant Travis
Upshur Victoria Waller Williamson Wilson Wise

Eligible Vehicles and Equipment:


Vehicles and equipment used primarily for competition or recreational purposes are not eligible for funding under any of the ERIG project categories. The TCEQ may more narrowly define or limit the types of eligible vehicles and equipment for a particular funding period. The types of vehicles and equipment eligible under the FY16 ERIG funding period include:

  • Heavy-Duty On-Road Vehicles: On-road vehicles with a gross vehicle weight rating (GVWR) greater than 8,500 lbs.
  • Heavy-Duty Non-Road Equipment: Non-road equipment powered by an engine greater than 25 horsepower (hp).
  • Stationary Equipment: Stationary engines of at least 25 hp.

ERIG 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 FY16 ERIG funding period include:

  • 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.
    • Vehicles and equipment being replaced must be in good operating condition with at least five years of remaining useful life.
    • The model year of the engine installed on a replacement vehicle must be 2012 or newer.
    • The manufacture year of the engine installed on replacement non-road equipment must be 2012 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.
    • For vehicles, the replacement must be of the same vehicle type, weight category, and body and axle configuration as the vehicle being replaced.
    • For equipment, the replacement must be of the same equipment type and intended for the same or similar purpose as the equipment being replaced.
    • For at least the two years immediately preceding the date of application, vehicles being replaced must have:
        • been owned, leased, or commercially financed by the grant applicant;
        • been continually registered in Texas; and
        • continuously had an up-to-date safety inspection.
    • For at least the two years immediately preceding the date of application, equipment being replaced must have been:
        • owned by the grant applicant; and
        • located and used in Texas.
  • 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.

 Operation Requirements for Grant-Funded Vehicles and Equipment:


  • Vehicles and Equipment funded under the ERIG Program are intended to reduce emissions within the eligible counties.
  • For equipment, the applicant must commit to at least 75% annual usage in the eligible counties.
  • For vehicles, the applicant must designate the percentage of annual mileage that will occur in the eligible counties, which may not be less than 25%. In addition to the percentage of use in the eligible counties, the applicant must commit to operating the vehicles at least 75% of annual usage in a combination of eligible counties and designated highways and roadways.
  • Grant recipients must monitor and report annually on mileage and location of use over the activity life of the grant (5, 6, or 7 years).

 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.
  • 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.

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.

How to Request a Determination of Emission Reduction Factors:


In addition, 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.
