Natural Gas - Corrosion Control

Operators must establish procedures to implement and maintain a corrosion control program for their piping system. These procedures should include design, installation, operation, and maintenance activities on a cathodic protection system. A person qualified in pipeline corrosion control methods must carry out these procedures.
