(h) Section 802.2 is added to Ordinance No. 3597 to read:
Section 802.2. After initial installation under this Ordinance of any pipeline used or to be used to carry toxic, corrosive or flammable liquids, such pipeline shall be subject to a hydrostatic pressure test as provided herein before it is placed in operation. The duration of the hydrostatic test for this purpose shall not be less than twenty-four (24) hours.
After repair or replacement of any pipeline used or to be used to carry toxic, corrosive or flammable liquids, made necessary to repair leaks or breaks, or replacements made necessary for changes required by improvements within the roadway, the affected portion of the pipeline shall be subjected to a hydrostatic pressure test as provided herein before placing in operation. The duration of the hydrostatic test for this purpose shall be not less than twenty-four (24) hours. However, no such test is required for a minor repair which does not require removal of the pipeline from operation. If the affected section is isolated and tested hydrostatically, pressure test of the tie-in welds is not required; however, tie-in welds shall be examined by radiographic means.
No pipeline subject to this Ordinance used or to be used to carry toxic, corrosive or flammable liquids and over ten (10) years of age, shall be operated beyond the successive ensuing 12-month period of time unless retested annually by a hydrostatic pressure test or other test means acceptable to the Commissioner. The duration of the periodic test for this purpose shall be less than four (4) hours.
Each pressure test, either initial or retest shall be in accordance with the American National Standard Institute's Code for Pressure Piping, Liquid Petroleum Transportation Piping Systems (ANSI B 31.4) in its latest revision. The Commissioner may authorize the use of a liquid petroleum that does not vaporize rapidly (i.e., flash point over 150°F or 66°C) as a test medium. Pressure tests after initial installation of pipelines and before they are placed in operation shall show no unexplained loss. Annual or retest pressure tests shall not show an hourly loss, for each section of the pipeline under test at the time, in excess of either ten (10) gallons, or the sum of one (1) gallon and an amount computed at a rate in gallons per mile equivalent to one-tenth (1/10) of the nominal internal diameter of the pipe.
The Commissioner may grant administrative waiver or other relief to an owner or operator under this Ordinance as to the periodic pressure testing of any pipelines as herein provided if owner or operator can demonstrate that such testing will cause the unreasonable unscheduled shutdown of plants, terminals, refineries, or other facilities of which such pipelines constitute an integral part.
In addition to the foregoing requirements, any pipeline authorized by this Ordinance and subject to pressure testing shall be subjected to a pressure test by the owner or operator at any time as may be required by the Commissioner in the interest of public safety.
Within thirty days after completion of any test made pursuant to the provisions of this Ordinance, the owner or operator shall submit a certified report of such test for the Commissioner's review. The report shall show the date of test, description or portion of pipeline tested identified with respect to County highways, and the test data. The report shall be sufficient in detail to permit analysis of test results and determination of compliance with the applicable provisions of this Ordinance or any other applicable Ordinance, rule or regulation. The report shall also contain any other test information as may be specifically requested by the Commissioner.

The cathodic protection system for all new ferrous pipelines carrying utility gases shall be installed in accordance with General Order No. 112-C of the Public Utilities Commission of the State of California. A test procedure shall be developed by the owner or operator to determine whether adequate cathodic protection has been achieved and submitted to the Commissioner for approval. Reports of cathodic protection evaluation in accordance with said approval procedure shall be made available annually for review by the Commissioner.
(k) Section 802.5 is added to Ordinance No. 3597 to read:
Section 802.5. Each owner or operator of a pipeline used or to be used to convey toxic, corrosive or flammable liquids shall have a written emergency plan approved and on file with the County Forester and Fire Warden. The plan shall be in accordance with the American National Standard Institute's Code for Pressure Piping, Liquid Petroleum Transportation Piping Systems (ANSI B 31.4) in its latest revision.
The plan shall include but not be limited to the following elements: (1) A "liaison" element for intercommunications between public agencies and pipeline owners or operators to provide for prompt coordinated remedial action, and the dissemination of information as to the location and ownership identification of pipelines based on the best available records and plans. (2) A "spill contingency" element to limit the extent of accidental product discharge by which pipeline owners or operators shall involve themselves in a cooperative pipeline leak notification emergency action system. (3) A "leak detection" element by which the pipeline owners or operators can monitor the flow of their product and can divert, reduce or stop the flow of said product at the first indication of a product leak. (4) A "first on the scene emergency containment" element in cooperation with other pipeline owners or operators to be utilized until arrival of the affected pipeline owners' or operators' personnel. "First on the scene" costs shall be borne by the owner or operator of the facility and shall be reimbursed to the organization effecting the emergency containment.

The permit application shall include a plat or other suitable means describing the facility or encroachment to be abandoned or removed and indicated its exact location. Permission to abandon a facility or encroachment without removing shall be subject to removal within one year after the effective date of the abandonment if the facility or encroachment may interfere with a present or future public improvement. If it is determined that the facility or encroachment should be removed, the permittee or its successor in interest shall remove it at its expense or pay County for the cost of such removal. Permittee shall leave any abandoned facility or encroachment in a safe condition.
In addition to the foregoing, abandonment in place of a pipeline used to convey toxic, corrosive or flammable liquids will be subject to the following requirements. The pipeline shall be thoroughly purged of liquids and vapors and filled with an inert material that will remain in a solid or semi-solid state if any portion of the pipeline is cut or removed in the future. The permittee shall file a certificate with the Commissioner that said requirements have been complied with and the abandoned pipeline has been left in a safe condition.
