Pressure testing

(a)Any pressure test performed pursuant to 49 CFR 192, Subpart J, as amended from time to time, shall:#

(1)be conducted using a gauge such that the test pressure is in the middle third of the range of the gauge;#

(2)be conducted at a test pressure of at least 150 percent of the desired MAOP or 90 pounds per square inch gauge, whichever is greater;#

(3)not be conducted against any valve separating the section being pressure tested from a Pipeline containing Gas, unless approved by the Authority in writing; and#

(4)be of a minimum duration in accordance with 49 CFR 192, Subpart J, as amended from time to time, or Table B20-1, whichever is greater. Table B20-1 - Minimum Pressure Test Duration Nominal Pipe Diameter (Inches) 30 Pipeline Length#

(b)Prior to applying any pressure test medium, the Pipeline being tested shall be opened to atmosphere to verify that no positive Gas pressure exists in the section to be tested.#

(c)The pressure test medium shall not be Gas when pressure testing a section of existing Low Pressure Main to allow for operation at High Pressure.#
