STANDARDSPart I. GeneralSection 1. Definitionsl.AB.D.Cathodic Protection Well.California Water Code as:A cathodic protection well is defined in Section 13711 of the"...any artificial excavation in excess of 50 feet constructed by any methodfor the purpose of installing equipment or facilities for the protectionelectrically of metallic equipment in contact with the ground, commonlyreferred to as cathodic protection."Enforcing Agen~. An agency designated by duly authorized local, regional, or Stategovernment to administer and enforce laws or ordinances pertaining to the construction,alteration, maintenance, and destruction of cathodic protection wells.Casing. All vent pipe, anode access tubing, electrical cable conduit, and other tubular materialsthat pass through the interval 10 be sealed.Conductor Casing. A tubular retaining structure temporarily or permanently installed in theupper portion of the well boring between the wall of the well boring and the inner well casing.Conductor casing is often installed to keep the borehole open during drilling if cavingconditions are expected. Despite its title, conductor casing does not normally serve an"electrical" function for cathodic protection wells.Section 2. Exemptions Due to Unusual Conditions.Under certain circumstances the enforcing agency may waive compliance with these standards and prescribealternate requirements. These standards may be waived only where they are impractical or ineffective becauseof unusual conditions, or would result in unsatisfactory condition or well function. In waiving any of thesestandards, the enforcing agency shall, if at all possible, require that measures be implemented to provide thesame or greater level of water-quality protection that would otherwise be provided by these standards.Section 3. Special Standards.The enforcing agency may prescribe measures more stringent than standards described here, where needed toprotect public safety or protect water quality.Section 4. Responsible Parties.Corrosion control engineers are normally responsible for the design and supervision of corrosion controlfacilities incorporating cathodic protection wells. Pursuant to Section 13750.5 (Division 7, Chapter 10, ~Article 3) of the California Water Code, construction, alteration, and destruction of cathodic protection wellsshall be performed by contractors licensed in accordance with the California Contractors' License Law.1 Technical terms are defined in Appendix A, page 77.~-64-c.
(Division 3, Chapter 9, California Business and Professions Code), except where exempted by law. Abovegroundelectrical facilities for cathodic protection wells should be installed by an appropriately licensedcontractor.Section 5. Reports.Cathodic protection well construction, alteration, and destruction reports shall be completed on formsprovided by the California Department of Water Resources. Other types of forms may be used for submissionto the Department with the prior approval of the Department. The completed forms shall be submitted tothe Department in accordance with relevant provisions of Sections 13750 through 13754 (Division 7, Chapter10, Article 3) of the California Water Code. Information concerning completion and submission of wellconstruction, alteration, and destruction reports is contained in Guide to the Preparation of the Water WellDrillers Report, Department of Water Resources, October, 1977, or its latest revision.-65-
