Gov. Code, § 51013

(a) Any new pipeline constructed after January 1, 1984, and which normally operates under conditions of constant flow and pressure, shall be designed and constructed in accordance with Subparts C and D of Part 195 of Title 49 of the Code of Federal Regulations, and shall include a means of leak detection and cathodic protection which the State Fire Marshal determines is acceptable, except that any pipeline which transports by gravity or operates at a stress level of 20 percent or less of the specified minimum yield strength of the pipe shall meet these design and construction requirements on or before January 1, 1991.

(b) Any new pipeline on which construction begins after January 1, 1990, shall be designed to accommodate the passage of instrumented internal inspection devices, and shall have leak mitigation and emergency response plans and equipment as the State Fire Marshal may require. Any repairs to existing pipelines which can accommodate instrumented internal inspection devices shall be done in a manner not to interfere with the passage of these devices.

(c) Subdivision (a) does not apply to the replacement of valves and the relocation or replacement of portions of pipelines.

(d) For pipelines which cannot accommodate internal inspection devices, replacements of portions of the pipe shall be done in a manner consistent, to the extent practicable, with the eventual accommodation of instrumented internal inspection devices.
