Excess Flow Valve Policy

An excess flow valve (EFV) is a mechanical safety device installed in a natural gas distribution line between the street and the residual meter. If there is a significant increase in the flow of gas (e.g., due to a damaged line), the EFV will “trip” or close to minimize the flow of gas through the line and thus, the amount of gas escaping into the atmosphere. During normal use, the valve is kept pushed open against oncoming gas flow by a spring. EFV’s are designed so that general usage such as turning on appliances, will not shut the valve. However, during a significant increase in flow of gas (e.g., due to a damaged line), the spring cannot overcome the force of the gas, and the valve will close and stay closed until the correct pressure is restored. When the correct pressure is restored, the EFV automatically resets itself.

EFV’s are placed in the service line outside the residence and are only for damage to outside lines. Damage or leaks on internal piping will most likely not have enough flow to “trip” or close the EFV.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) has amended regulation 49 CFR Part 192 that gives every residential customer the right to request the installation of an EFV on their natural gas service line. Pursuant to LCUB board policy the EFV will be placed in the residential natural gas service line at the prevailing rate and at the customer’s expense. Rates for EFV installation are currently:

$226.33 FOR PE LINE INSTALL

$454.46 FOR STEEL LINE INSTALL

Customers interested in having an EFV placed on their natural gas service line may call LCUB for more information at 1-844-Our-LCUB (1-844-687-5282).
