Petroleum/Propane/Anhydrous Ammonia Program

The program combines a variety of services. Petroleum dispensers, petroleum terminal meters and fuel delivery truck meters are tested for accuracy; premises where petroleum products are stored and/or sold are inspected for safety; metered LPG delivery vehicles and dispensers are checked for accuracy; and storage and handling of anhydrous ammonia are monitored.

History of the Program

The Petroleum/Propane/Anhydrous Ammonia program provides a variety of services to ensure consumer protection and public safety across Missouri. Under this program, petroleum and propane fuel dispensers located at service stations, marinas, airports, bulk plants, pipeline and barge terminals and other retail/wholesale locations are inspected and tested for accuracy. Propane/petroleum fuel delivery truck meters are also checked for accuracy. To protect the public from fire, explosion and injury, petroleum and anhydrous ammonia safety inspections are also performed.

The inspection program works in cooperation with a number of state and federal agencies, including the Environmental Protection Agency, Federal Trade Commission, Missouri Highway Patrol, Department of Natural Resources, Department of Transportation, Internal Revenue Service, Department of Revenue and the State Fire Marshall.

In conjunction with the 2005 Federal Energy Policy Act, a law was enacted on August 28, 2006 that requires manufacturers and installers of aboveground and underground storage tanks and piping to maintain financial responsibility that would cover the costs of corrective action related to petroleum releases. This documentation is to be submitted to the Department of Agriculture annually and will expire one year from date of the issuance.

Petroleum Inspection Program (Chapter 414.142 RSMo.)

The Petroleum Inspection Program provides safety inspections of:

In addition to the Missouri Code of State Regulations (CSR), Missouri has adopted the safety standards of the National Fire Protection Association (NFPA) 30, 30A and NEC 70, 1996 Edition.

The Petroleum Inspection Program checks device accuracy at:

In addition to the Missouri Code of State Regulations (CSR), Missouri has adopted the National Institute of Standards and Technology (NIST), Specifications and Tolerances and other requirements for weighing and measuring devices.

LP Gas Inspection Program (Chapter 323.020 RSMo.)

The LP Gas Inspection Program checks device accuracy of:

In addition to the Missouri Code of State regulations, Missouri has adopted the National Institute of Standards and Technology (NIST) Handbook 44, Specifications, Tolerances and Other Requirements for Weighing and Measuring Devices as device standards.

Anhydrous Ammonia Inspection (Chapter 266 RSMo.)

The Anhydrous Ammonia Inspection provides safety inspections of:

The American National Standards Institute (ANSI) 1981 Edition, has been adopted as the safety standard for Missouri.

Liquid Measuring Devices

The next time you pump gas into your car, remember there’s someone out there making sure you get the amount you pay for. The Missouri Weights, Measures and Consumer Protection Division checks the accuracy of motor fuel dispensers, refined-fuels terminal meters, liquid propane meters (trucks and dispensers), and refined fuels delivery truck meters.

Specifications for liquid-measuring devices have been adopted from the National Institute of Standards and Technology (NIST) Handbook 44 Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices. This publication can be obtained for a fee from the U.S. Government Printing Office, Washington, DC 20402, phone: (202) 783-3238.

Petroleum Inspection Financial Responsibility Registration

In 2005, the Federal Energy Policy Act was enacted by US Congress. One of the five provisions addressed by this law is the requirement for financial responsibility of manufacturers and installers. This new law requires persons who manufacture an aboveground or underground storage tank for use in this state, or piping for such tank, or who install or repair tanks or piping in this state, to maintain evidence of financial responsibility in an amount equal to or greater than one million dollars per occurrence and two million dollars annual aggregate for the costs of corrective action directly related to releases caused by improper manufacture, installation, or repair of such tank or piping. This requirement does not apply to installation or repairs of fuel tanks or piping by the owner or operator of such fuel tank or piping.

Companies are required to submit proof of insurance annually and will expire one year from the date of issuance, as specified in 2 CSR 90-30.085. Once your application is approved, a registration number and certificate will be issued to your company. The registration list will be continuously updated. If you have any questions regarding this information, please contact John Albert at (573) 751-5636.

Safety Inspections of Motor Fuel Dispensing Systems

The Weights, Measures and Consumer Protection Division makes sure you’re safe at places where motor fuels are stored and dispensed. Aboveground storage tanks, fuel dispensing devices, as well as piping, valves, and fittings, are inspected to ensure they are safe. Safety standards for these inspections have been adopted from the National Fire Protection Association (NFPA).

Propane/Anhydrous Ammonia Program

The Division of Weights, Measures and Consumer Protection inspects liquid propane meters, anhydrous ammonia applicators, nurse tanks, and storage equipment. Specifications for liquid propane meters have been adopted from NIST Handbook 44 Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices. Anhydrous ammonia safety standards have been adopted from the American National Standards Institute. Propane meter inspection fee is $25 per meter. Propane safety is regulated by the Missouri Propane Gas Commission.
