Current through Register 2024 Notice Reg. No. 28, July 12, 2024
A park gas piping distribution system is subject to the
					 Pipeline Safety Law of 1994 and regulations adopted by the Office of Pipeline
					 Safety Operations. The applicable regulations are contained in Title 49 of the
					 Code of Federal Regulations, Parts 191 and 192.
(a) The operator of a park gas piping system
				  is responsible for complying with the federal regulations in addition to this
				  chapter. A permit is not required from the enforcement agency for the
				  installation of cathodic protection if the existing gas piping system is not
				  otherwise altered.
This chapter does not prohibit the installation of cathodic
					 protection systems and requirements for corrosion control of buried or
					 submerged metallic gas piping systems required by the federal regulations in
					 existing systems. If there is any conflict between the provisions of this
					 chapter and the federal regulations, the provisions of the federal regulations
					 shall prevail.
(b) Plans and
				  specifications for the installation of a metallic gas piping system shall
				  specify methods of protecting buried or submerged pipe from corrosion,
				  including cathodic protection, unless it can be demonstrated that a corrosive
				  environment does not exist in the area of installation. The design and
				  installation of a cathodic protection system shall be carried out by, or under
				  the direction of, a person qualified by experience and training in pipeline
				  corrosion methods so that the cathodic protection system meets the requirements
				  of Title 49 of the Code of Federal Regulations, Parts 191 and 192.
(1) All buried or submerged metallic gas
				  piping shall be protected from corrosion by approved coatings or wrapping
				  materials. All gas piping protective coatings shall be approved types, machine
				  applied, and conform to recognized standards. Field wrapping shall provide
				  equivalent protection and is restricted to those short sections and fittings
				  necessarily stripped for threading or welding. Risers shall be coated or
				  wrapped to a point at least six (6) inches above grade.
(2) All metallic gas piping systems shall be
				  installed in accordance with plans and specifications approved by the
				  enforcement agency, including provisions for cathodic protection. When the
				  cathodic protection system is designed to protect only the gas piping system,
				  the gas piping system shall be electrically isolated from all other underground
				  metallic systems or installations. When a cathodic protection system is
				  designed to provide all underground metallic systems and installations with
				  protection against corrosion, all such systems and installations shall be
				  electrically bonded together and protected as a whole.
(3) When non-metallic gas piping is installed
				  underground, a locating tape or No. 18 AWG or larger copper tracer wire shall
				  be installed with and attached to the underground piping for the purpose of
				  locating the piping system. The locating tape or tracer wire shall terminate
				  above grade at an accessible location at one or more ends of the piping system.
				  Every portion of a plastic gas piping system consisting of metallic risers or
				  fittings shall be cathodically protected against corrosion.
