Pipeline Safety Department

The Oklahoma Corporation Commission’s (Commission) Transportation

Division, acting through the Pipeline Safety Department (Department), administers the Commission’s intrastate regulatory program to assure the safe transportation of natural gas, petroleum, and other hazardous materials by pipeline. The Commission develops regulations and other approaches to assure safety in design, construction, testing, operation, maintenance, and emergency response to pipeline facilities. The Commission derives its authority over intrastate pipeline operations through state statutes and certification agreements with the U.S. Department of Transportation.

The Commission’s safety jurisdiction over pipelines covers more than 300 intrastate gathering, transmission, and distribution operators and 10 intrastate hazardous liquid operators. Combined, there is more than 40,000 miles of pipeline subject to the Commission’s jurisdiction. The Department currently has twelve employees; two work at the Commission’s office in Oklahoma City and the others work out of their homes; Oklahoma City, Enid, Weatherford, Norman, Seminole, Shawnee, Tulsa, and Fairfax. These employees work within the gas and hazardous liquid pipeline safety programs to carry out the mandated regulatory and enforcement responsibilities of the Oklahoma Corporation Commission.
