Section 245.445 - Methods of release detection for piping
Current through Register Vol. 54, No. 44, November 2, 2024
Each method of release detection for piping used to meet the requirements in § 245.442 (relating to periodic monitoring requirements for petroleum underground storage tank systems) shall be conducted in accordance with the following:
(1) Automatic line leak detectors. Methods which alert the operator to the presence of a leak by restricting or automatically shutting off the flow of regulated substances through piping or triggering an audible or visual alarm may be used only if they detect leaks of 3 gallons-per-hour at 10 pounds per square inch line pressure within 1 hour. An annual test of the operation of the automatic line leak detector shall be conducted in accordance with the manufacturer's requirements.
(2) Line tightness testing. A periodic test of piping may be conducted only if it can detect a 0.1 gallon per hour leak rate at 1 1/2 times the operating pressure.
(3) Applicable tank methods. The methods in § 245.444(4)-(8) (relating to methods of release detection for tanks) may be used if they are designed to detect a release from any portion of the underground piping that routinely contains regulated substances.
