Excess Flow Valve Notification for Residential Customers

As required by the U.S. Department of Transportation (DOT), you are hereby notified that an excess flow valve ("EFV") which meets the minimum DOT performance standards is available for installation on your natural gas service line. Please note that such a device is not required for the normal, safe operation of your service line, but could help to mitigate the consequences of a service line failure (i.e. break, rupture, etc.).

Safety Benefits

An EFV is a safety device that is designed to automatically stop the flow of natural gas when (if) the flow of gas through the device exceeds a pre-determined rate. The device is normally installed at (near) the service line's connection to the gas distribution main, and protects against the uncontrolled escape of natural gas should the downstream line be broken/severed. It should be noted that these devices generally do not protect against slow leaks such as those caused by corrosion, loose fittings, or leaks beyond the gas meter (house piping).

The use of EFVs has been primarily precipitated by service line incidents caused by accidental digging by excavators. Such incidents account for about 1/3 of the natural gas pipeline incidents in the United States. While the use of an EFV may help to limit the effects/damages of such an incident, the best prevention against such incidents is to ensure that those who may have reason to be excavating on your property to call 811.


Installation of an EFV

As with any mechanical device, an EFV may malfunction, thereby causing a temporary loss of natural gas service. Should such a malfunction occur within one (1) year of the date of installation, repair or replacement costs will be the responsibility of Ohio Valley Gas. Any need for repair or replacement of an EFV which may occur beyond this one (1) year "warranty" period, will result in time and material charges to the customer of record.

Questions may be addressed to your local Ohio Valley Gas Office.
