Torrance Municipal Code Art. 10 Testing of Pipelines

a) The provisions of this Article shall apply to any pipeline located in any street, alley, or in any other public way or in any public property, which pipeline operates at pressures in excess of twenty (20) percent of the specified minimum yield strength of the pipe and which is used for conveying flammable liquid.

b) The provisions of this Article shall not apply to any pipeline of any public utility regulated by the Public Utilities Commission of the State of California for which testing regulations have been established by said Commission.

a) Within thirty (30) days after repair or replacement of any pipeline or section thereof, a pressure test shall be conducted between the block valves in which such affected portion is located.

b) A pressure test shall be conducted annually for each pipeline which is over ten (10) years of age.

a) Pressure tests shall not show an hourly loss for each section of the pipeline under test at the time in excess of either twelve (12) gallons or the sum of three (3) gallons and an amount computed at a rate in gallons for the equivalent to one-tenth (1/10) of the nominal internal diameter of the pipe, whichever is the lesser.

b) The City Engineer may witness the entire test procedure, and during a test, or at any other time, may measure or ascertain the pressure to which the pipe is subject.

The owner or operator of each pipeline shall submit to the City Engineer at least once each year a report of the pressure test made pursuant to the provisions of this Article. Such reports shall show the date of the test, the description of the portion of the pipe tested which should be identified with respect to City street routes, and test data sufficient in detail to permit analysis of test results and determination of compliance with the provisions of Section 74.10.3.
