Section 335-6-15-.18 - Methods Of Release Detection For Underground Piping

Each method of release detection for underground piping used to meet the requirements of Rule 335-6-15-.15 must be conducted in accordance with the following:

(a)Automatic line leak detectors. Methods which alert the operator to the presence of a leak by restricting or shutting off the flow of regulated substances through underground piping may be used. Beginning August 6, 2008 and thereafter, methods which alert the operator to the presence of a leak by triggering an audible or visual alarm may be used only if they also restrict or shut off the flow of regulated substances through underground piping; except beginning December 8, 2017, emergency power generator UST systems may use audible or visual alarm methods without restricting or shutting off flow. All automatic line leak detector methods must 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 leak detector must be conducted in accordance with rule 335-6-15-.14(1)(c).

(b)Line tightness testing. A periodic test of underground piping may be conducted only if it can detect a 0.1 gallon per hour leak rate at one and one-half times the operating pressure. When a test method is required by the manufacturer to be performed manually, the test must be performed by an individual having current certification of training from the manufacturer of the test method.

(c)Underground storage tank methods applicable to piping. Except as described in rule 335-6-15-.15(a), any of the methods in rule 335-6-15-.17(e) through (i) may be used if they are designed to detect a release from any portion of the underground piping that routinely contains regulated substances.
