DOT Renews Farm Cart Extension for Propane


Washington, D.C. (November 1, 2004)—The U.S. Department of Transportation (DOT) has renewed the farm cart exemption (E-11209) authorizing the transportation of liquefied propane gas in non-DOT specification cargo tank motor vehicles exclusively for agricultural purposes when operated by a private carrier.

The previous exemption was set to expire September 30, 2004. The renewed exemption is valid through August 30, 2006.

“This extension is encouraging news as the propane industry continues to increase the demand for clean, efficient, and reliable propane through innovative technologies like poultry house sanitation and weed control and proven applications such as grain drying, farm heating and irrigation,” said Propane Education & Research Council (PERC) Agriculture Programs Manager Mark Leitman.

The exempt transportation is limited to the movement of a cargo tank, which has been charged to the appropriate filling limits as specified in the regulations, between one field and another using the shortest practical distance on public roads. Transportation of a cargo tank between the point of use and a propane distribution facility is limited to the tank containing no more than 5 percent of its water capacity.

In order to qualify for the exemption, cargo tanks must have a minimum design pressure of 250 pounds per square inch gauge (psig), meet the requirement of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code at the time the tank was manufactured, and be marked accordingly. Plus, cargo tanks must have a water capacity of 1,200 gallons or less, conform to National Fire Protection Association Code 58, and be mounted securely on a motor vehicle.

A copy of the exemption must be carried aboard each motor vehicle used to transport propane. In addition, a copy of the exemption must be maintained at each facility where propane is sold or reoffered for transportation.

DOT’s Research and Special Programs Administration authorized the extension requested by the National Propane Gas Association (NPGA), which has also submitted a petition to revise the hazardous material regulations that would incorporate the terms of the farm cart exemption.

The National Propane Gas Association (NPGA) is listed as the grantee of the exemption, NPGA members can download a copy of the exemption by visiting and clicking on "Issues/Regulatory Links and Information."  Non-NPGA members who wish to be covered by this exemption should contact Michael Caldarera of NPGA at for a copy.

PERC’s vision in agriculture is that by 2010, the agricultural industry will recognize propane as a preferred energy source offering exceptional value. This value is achieved through a unique combination of product benefits, including cost-effectiveness, efficiency and productivity, reliability, portability, and environmental friendliness.
