Excess Flow Valve Message

Hastings Utilities started installing an EFV on new and replacement service lines in 1999 when appli- cable. We then started installing them on all new and replacement single residence meter sets in 2008. The Pipeline and Hazardous Materials Safety Administrations has recently issued a new regulation that requires Hastings Utilities to require the installation of an Excess Flow Valve (EFV) on all new natural gas service lines to residential and small commercial customers. The regulations also allow certain existing residen- tial and small commercial customers whose total appliance load is no greater than 1,000 cubic feet per hour (approximately 1,000,000 BTU per hour) to request the installation of an EFV on their natural gas service lines.

Because the service line must be excavated to install an EFV, you will be charged $2000 to cover the cost of installation should you request one. Hastings Utilities will be responsible for EFV maintenance costs after installation.

An Excess Flow Valve (EFV) is an extra safety device that can be installed in a service line providing natural gas to the meter.  The main purpose of an EFV is to reduce the risk of a release of natural gas caused by excavation damage to the service line between the point of connection to the main and the meter. The de- creased flow of natural gas reduces the risk of personal injury and property damage that could occur if the es- caping gas ignites. An excess flow valve will not protect against minor gas leaks on the service line or gas me- ter, or any leak on customer piping inside a home or business. Not every service can accommodate an EFV.

The illustration below shows some typical causes of broken service lines, including excavation dam- age. Remember – the best prevention against damaging your service line is to have all belowground utility lines marked before digging.
