Does my conversion need to be EPA certified?

Answer: Yes, the conversion must be EPA certified. Under R307-121-4 (6) andR307-121-5(7) the proof of certification required in 59-10-1009(1)(b) or 59-7-605(1)(b) refers to the copy of the EPA certification for the conversion.  This means that the manufacturer of the conversion equipment has to get the conversion equipment tested on your type of vehicle and supply you with a Certificate of Conformity indicating that the conversion conforms with EPA standards.


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 would need to be performed at a special facility (some of which can be found here http://www.epa.gov/otaq/consumer/lablist.pdf PDF file).


In a letter dated February 3, 2006, EPA provided information for small volume manufacturers' who convert vehicles and engines to operate on alternative fuels. In a letter dated September 1, 2005 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

Where can I obtain the proof of certification that would satisfy the requirements of 59-10-1009(1)(b) or 59-7-605(1)(b)?

Answer: One way is to request the EPA Certificate of Conformity from the manufacturer of the conversion equipment or the vendor that sold and/or installed the conversion  equipment. Another way is to click here to obtain a Certificate of Conformity. Then enter the "Certificate of Conformity" in the first drop down list, "Light-Duty Vehicles and Trucks" in the second drop down list, and then enter the name of the vehicle or conversion company (e.g. Baytech, Technocarb, etc.) from the manufacturer drop down list, and hit "Search."  This should pull up the current certificates for each vehicle or conversion company.

Is the title good enough to show proof of purchase?

Answer: The title by itself is not sufficient to show proof of purchase. If there is no bill of sale you may need some other type of documentation. Please contact Mat Carlile 536-4136.

What are incremental costs?  How much are the qualifying expenditures that I can claim on the TC-40V form?

Answer:The amount you may claim is not the amount you paid for the vehicle.  Rather, it is the difference between the cost of a new clean fuel vehicle and the cost of the same model without the clean fuel system. For example, say the CNG option cost $7,000 when the vehicle was new. That is the incremental cost. Half of that is $3,500. However, since the credit is capped at $3,000, you would receive a $3,000 tax credit in this example.

Please consider the following examples:

Where can I get my vehicle converted?

Answer: Utah Division of Air Quality is providing these lists as a reference only and does not endorse any conversion kit or company. EPA maintains a list of manufacturers' who convert vehicles and engines to operate on alternative fuels. In addition, Utah Clean Cities also maintains a list of conversion companies that you would be able to obtain a conversion kit from; however, they might not necessarily be EPA certified.

How do I get my conversion certified?

Answer: 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 here http://www.epa.gov/otaq/consumer/lablist.pdf PDF file) and obtain a certificate of conformity.

If you are a small volume manufacturer who convert vehicles and engines to operate on alternative fuels, EPA provided information on how to get their conversions certified in a letter dated February 3, 2006 .

In a letter dated September 1, 2005 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.


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.
