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. (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.

   1. (i) Except as provided in subparagraph (ii), underground storage tank systems installed or replaced after November 10, 2007, must have automatic line leak detectors with an automatic pump shut-off device that shuts off the flow of regulated substances through pressurized piping that routinely contains and conveys product from the tank (See § 245.421(a)(1) (relating to performance standards for underground storage tank systems).)
   2. (ii) Owners and operators of underground storage tank systems that store fuel solely for use by emergency power generators shall install methods that trigger an audible or visual alarm to meet the requirements in this subsection.
   3. (iii) Except as provided in subparagraph (ii), pressurized piping installed on or before November 10, 2007, that conveys regulated substances must be equipped with a method that restricts or automatically shuts off the flow of regulated substances and meets the requirements in this section if the storage tank facility is unattended while open for business.
2. (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. (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.
