SUBCHAPTER 4 RELEASE DETECTION §11-280.1-40 General requirements for all UST systems. (a) Owners and operators of UST systems must provide a method, or combination of methods, of release detection that: (1) Can detect a release from any portion of the tank and the connected underground piping that routinely contains product; (2) Utilizes equipment compatible with the regulated substances being stored; (3) Is installed, calibrated, operated, and maintained in accordance with the manufacturer's instructions; (4) Is operated and maintained, and electronic and mechanical components are tested for proper operation, in accordance with one of the following: manufacturer's instructions; a code of practice developed by a nationally recognized association or independent testing laboratory; or requirements determined by the department to be no less protective of human health and the environment than the requirements of paragraphs (1) to (3). All maintenance and service of the release detection equipment must be conducted by a technician with 280.1-47 §11-280.1-40 current certification or training appropriate to the equipment serviced. A test of the proper operation must be performed at least every three hundred sixty-five days, or in a time frame recommended by the equipment manufacturer, whichever is more frequent. Beginning July 15, 2019, as applicable to the facility, the test must cover at a minimum the following components and criteria: (A) Automatic tank gauge and other controllers: test alarm; verify system configuration; test battery backup; (B) Probes and sensors: inspect for residual buildup; ensure floats move freely; ensure shaft is not damaged; ensure cables are free of kinks and breaks; test alarm operability and communication with controller; (C) Automatic line leak detector: test operation to meet criteria in section 11-280.1-44(1) by simulating a leak; (D) Vacuum pumps and pressure gauges: ensure proper communication with sensors and controller; and (E) Hand-held electronic sampling equipment associated with groundwater and vapor monitoring: ensure proper operation; and (5) Meets the performance requirements in section 11-280.1-43 or 11-280.1-44, as applicable, with any performance claims and their manner of determination described in writing by the equipment manufacturer or installer. In addition, the methods listed in section 11-280.1-43(2), (3), (4), (8), (9), and (10) and section 11-280.1-44(1), (2), and (4) must be capable of detecting the leak rate or quantity specified for that method in the corresponding section of the rule with a probability of detection of 0.95 and a probability of false alarm of 0.05. 280.1-48 3 5 8 4 §11-280.1-41 (b) When a release detection method operated in accordance with the performance standards in section 11-280.1-43 or 11-280.1-44 indicates a release may have occurred, owners and operators must notify the department in accordance with subchapter 5. (c) Any UST system that cannot apply a method of release detection that complies with the requirements of this subchapter must complete the change-in-service or closure procedures in subchapter 7.
