Section 615.1 - Cathodically Protected Metallic PipelinesPipelines installed within the Department's right-of-way shall be cathodically protected in such a manner as to ensure that the installation is electrically continuous and dielectrically isolated from grounded State Water Project structures and permittee's supplied equipment. All submittals shall include details of the cathodic protection system (CPS) and its appurtenances.
(a) All existing State Water Project cathodic protection test stations shall be located by the permittee prior to any grading or excavation. Additionally, all existing State Water Project cathodic protection test stations shall be: (1) Staked and flagged by the permittee.(2) Enclosed or protected during construction of the encroachment as approved by the Department.(b) Any relocation or modification of the State Water Project's cathodic protection test stations shall not be allowed. Exceptions to this policy may be considered by the Department only if the applicant demonstrates that the relocation or modification will not affect the Department's ability to maintain cathodic protection of the State Water Project.(c) Non-welded mechanical, stab, or gasketed pipe joints shall be continuity bonded with one (1) #8 AWG (American Wire Gauge) HMWPE (High Molecular Weight Polyethylene) cable attached by the thermite weld process or inductive weld stud process. The weld area and exposed cable shall be coated with a one-hundred (100) percent solids epoxy or covered with a butyl-rubber weld cap specifically designed for this purpose.(d) Insulating flange kits, insulating unions, and insulating fittings shall be used at locations where there is contact with grounded structures, including but not limited to: pumps, electric valves, telemetering systems, and vault penetrations.(e) Cathodic protection shall be provided by the use of sacrificial anodes, unless the proposed installation is a continuation of an existing pipeline where impressed current cathodic protection is presently in use. Additional impressed current cathodic protection equipment may be considered by the Department only if the applicant demonstrates that the additional equipment will not affect the Department's existing or future corrosion protection systems.(f) A means of monitoring the effectiveness of the CPS shall be provided by the applicant within the Department's right-of-way. The number of anodes and test stations may differ with each project. The application and monitoring of the CPS shall conform to Sections 195.567 through 195.588, inclusive, Title 49 of the Code of Federal Regulations, Part 195, Department of Transportation, "Transportation" (REV 10/1/2010), hereby incorporated by reference.Cal.
