Gas Control Technologies Inc. leakage detection survey process begins by reviewing the current natural gas distribution system mapping or as-builts to determine location of the natural gas main and service systems. The underground natural gas distribution system is then assessed using a flame ionization detector, which is the most technologically advanced equipment available, measuring samples as low as one part per million. When natural gas, methane or fuel based leakage is detected, a continuing study is performed to determine the extent of migration and to establish a priority level. All found leakage is prioritized using the American Society of Mechanical Engineer’s (ASME) Guide for Gas Leak Classifications, which is an industry wide standard for natural gas safety.
At the completion of the gas leak assessment survey a report is compiled providing all prioritized leakage locations and extent of gas migration patterns with specific location measurements with respect to buildings and other fixed reference points. Gas Control Technologies will provide our recommendations for repairs and replacement options including proposals for all Priority 1 leakage or necessary repairs upon your request.
Natural Gas Leak Detection Survey Requirements
In 1996 the United States Department of Transportation passed a ruling requiring owners of utility systems to advise their customers who own property with gas distribution piping systems of the potential hazards resulting from corrosion and leakage.
The United Sates Department of Transportation states under Title 49 of the Pipeline Safety Regulations that all property owners with underground or above ground gas distribution piping systems are responsible for the maintenance of their own gas distribution facilities. Therefore, all such owners are responsible for conducting gas leak surveys at least once each calendar year, at intervals not exceeding 15 months. Code of Federal Regulations 192.723 and 192.16
Our goal is to provide a complete understanding of your underground natural gas distribution system, detecting and ultimately assisting in eliminating unknown migrating gas leakage at or near building foundations thus providing a safe environment.
