Clean Fuel Vehicle Tax Credit

 

Rules for Vehicles Purchased After January 1, 2009

Converted Vehicles (Natural Gas or Propane)

| Converting | EPA Certification | Getting Certified | Proof of Certification |

Taxpayers may claim a non refundable tax credit of fifty percent of the cost of equipment for conversion minus any grant received, up to $2,500 per vehicle registered in Utah if:

  • it is to be fueled by propane, natural gas, or electricity;
  • it is to be fueled by another fuel determined by the Air Quality Board to be as effective as the above listed fuels; or,
  • it will meet the clean fuel vehicle standards in the Clean Air Act; and,
  • a previous owner did not take the same credit.

Required Documentation to be submitted with TC40V

The following are the requirements to demonstrate eligibility for Motor Vehicles converted to Natural Gas or Propane:

  • The VIN;

  • fuel type before and after the conversion;

  • if the vehicle is registered within a county with an inspection and maintenance (I/M) program, a copy of the vehicle inspection report from an approved station showing that the converted clean fuel vehicle meets all county emissions requirements for all installed fuel systems, or 2) in all other areas of the State a signed statement by an Automotive Service Excellence (ASE) certified technician that includes the Tech ASE number and the VIN stating that the conversion is functional;

    • Each of the following:

      • the conversion manufacturer;
      • the conversion equipment model number;
      • the date of the conversion; and
      • the name, address, and phone number of the person that converted the vehicle

    • One of the following:

      • EPA Certificate of Conformity
      • Executive Order from the California Air Resources Board
      • " Approval" of conversion consistent with requirements outlined in 76 FR 19830 April 8, 2011.

    • an original or copy of the purchase order, customer invoice, or receipt; and
    • a copy of the current Utah vehicle registration.

Proof of purchase requirements for vehicles converted to natural gas or propane can be found in R307-121-5.

The following are the requirements to demonstrate eligibility for Motor Vehicles converted to run on electricity:

  • the VIN;
  • the fuel type before and after the conversion;
  • each of the following:

    • the conversion equipment manufacturer,
    • the conversion equipment model number,
    • the date of the conversion, and
    • the name, address, and phone number of the person that converted the motor vehicle;
    • an original or copy of the purchase order, customer invoice, or receipt; and
    • a copy of the current Utah vehicle registration.

  • If the converted motor vehicle does not have any auxiliary sources of combustion emissions, then the applicant shall submit a signed statement by an ASE-certified technician that includes the VIN, the technician's ASE certification number, and states that the conversion is functional, and that the converted motor vehicle does not have any auxiliary source of combustion emissions.
  • If the converted motor vehicle has an auxiliary source of combustion emissions, then the applicant shall submit:

    • a copy of the vehicle inspection report from an approved station showing that the converted motor vehicle meets all county emissions requirements for all installed fuel systems if the motor vehicle is registered within a county with an I/M program, or
    • in all other areas of the State, a signed statement by an ASE-certified technician that includes the VIN and states that the conversion is functional, and
    • One of the following:

      • EPA Certificate of Conformity
      • Executive Order from the California Air Resources Board
      • "Approval" of conversion consistent with requirements outlined in 76 FR 19830 April 8, 2011.

Proof of purchase requirements for vehicles converted to electricity can be found in R307-121-6.

EPA Certification

To claim the Clean Fuel Vehicle Tax Credit a conversion must provide one of the following items:

  1. EPA Certificate of Conformity
  2. Executive Order from the California Resources Air Board, or
  3. “Approval” of conversion consistent with requirements outlined in 76 FR 19830 April 8, 2011

Testing is allowed by statute—subject to the criteria in 40 C.F.R. Part 86. Such tests must be performed at a special facility (some of which can be found in the EPA's Independent Vehicle Emissions Testing Laboratory Listing document).

Q. How do manufacturing companies get engines certified?

To obtain an EPA Certificate or a CARB Executive Order, the manufacturer must submit substantial emissions performance data and related documentation for each test group or engine family to be reviewed. Additionally, new converters may be asked to submit a converted vehicle for rigorous testing to verify this data.

Q. Why is this testing required?

This testing ensures that the retrofitted vehicle meets the same stringent emissions requirements as original equipment vehicles. The testing also ensures that the conversion system works seamlessly with the on-board diagnostics system to warn the driver when emissions are outside of approved parameters and to log those anomalies in the computer memory for downloading by the automotive service technician.

Proof of Certification

EPA Certificate of Conformity
Taxpayers can obtain the EPA Certificate of Conformity from the manufacturer of the conversion equipment or from the vendor that sold and/or installed the conversion equipment.

Another option is to visit the EPA Web site, then enter:

    1. the "Certificate of Conformity" in the first drop down list;

    2. "Light-Duty Vehicles and Trucks" in the second drop down list;

    3. the name of the vehicle or conversion company (e.g., Baytech, Technocarb, etc.) from the manufacturer drop down list; and then,

    4. select "Search," which should pull up the current certificates for each vehicle or conversion company.

    EPA-Compliant Conversion Systems
    EPA keeps a list of conversion systems that have meet the applicable emission standards and are exempt from the Clean Air Act tampering prohibition. Certified conversion systems may be applied to new, intermediate age, or outside useful life vehicles/engines covered by the conversion certificate. For more information, review the list of conversion systems that have meet EPA's requirements.

Getting a Conversion Certified

Each year a growing number of vehicle engines can be fitted with EPA certified conversion equipment that will allow a vehicle to operate on natural gas or propane. These conversions typically are "engine specific." Conversions are subject to the criteria in 40 C.F.R. Part 86, which are EPA standards. Manufacturers of the conversion equipment would have to get the conversion equipment tested on your type of vehicle and supply you with a certificate that the conversion conforms with EPA standards, or you would need to get the test at a special facility (some of which can be found in the EPA's Independent Vehicle Emissions Testing Laboratory Listing document) and obtain a Certificate of Conformity. If you are a small volume manufacturer who converts vehicles and engines to operate on alternative fuels, the EPA provided information on how to get their conversions certified in a letter dated February 3, 2006.

In a letter dated September 1, 2005, the EPA provided guidance for aftermarket alternative fuel converters on how to obtain EPA approval of the on-board diagnostics (OBD) II system. This guidance applies to converters who certify 2005 and later model year (MY) light-duty vehicles, light-duty trucks, and medium-duty passenger vehicles, and 2007 and later MY heavy-duty vehicles. EPA provided further guidance to small volume manufacturer with its June 20, 2009 letter.

If a Certificate of Conformity is not available for your vehicle, testing is allowed by statute—subject to the criteria in 40 C.F.R. Part 86—to obtain an EPA Certificate of Conformity. Such tests must be performed at a special facility (some of which can be found in the EPA's Independent Vehicle Emissions Testing Laboratory Listing document).
