17.56.409    RELEASE DETECTION RECORDKEEPING

(1) All UST system owners and operators shall maintain records in accordance with ARM 17.56.305 demonstrating compliance with all applicable requirements of this subchapter. These records must include the following:

(a) all written performance claims pertaining to any release detection system used, and the manner in which these claims have been justified or tested by the equipment manufacturer or installer, must be maintained for the operating life of the release detection system;

(b) the results of any sampling, testing, or monitoring must be maintained for at least one year, or another reasonable period of time determined by the department, except as follows:

(i) the results of annual tests of proper operation of leak detection equipment conducted in accordance with ARM 17.56.401(2) must be maintained for three years minimum. The results must list each component tested, indicate whether each component tested meets the criteria in ARM 17.56.401(2) or needs to have action taken, and describe any action taken to correct an issue;

(ii) the results of tank tightness testing conducted in accordance with ARM 17.56.407(1)(c) must be retained until the next test is conducted; and

(iii) the results of line tightness testing and vapor monitoring using a tracer compound placed in the tank system conducted in accordance with ARM 17.56.1601(1)(a)(iii) must be retained until the next test is conducted;

(iv) written documentation of all calibration, maintenance, and repair of release detection equipment permanently located on-site must be maintained for at least one year after the servicing work is completed, or for another reasonable time period determined by the department; and

(d) UST systems installed, modified, or replaced after November 26, 2009, shall document the communication of all sensors with the console at least monthly, and maintain the record onsite of each monthly sensor test for the previous 12 months.

(e) UST systems installed, modified or replaced after October 13, 2018, shall maintain records of site assessments conducted under ARM 17.56.407(1)(e) or (f) as long as the leak detection methods are used.

(f) records of site assessments conducted under ARM 17.56.407(1)(e) or (f) after October 13, 2018, must be signed by a professional engineer or professional geologist, or equivalent licensed professional with experience in environmental engineering, hydrogeology, or other relevant technical discipline acceptable to the department.
