PURPOSE: This rule outlines the minimum requirements for leak and spill detection systems.
(1) Owners and operators of underground storage tank (UST) systems that are in use must use a method, or combination of methods, or release detection that—
- (A) Can detect a release from any portion of the tank and the connected underground piping that routinely contains a regulated substance, except remote fills and gravity piping;
- (B) Is installed, calibrated, operated, and maintained in accordance with the manufacturer’s instructions, including routine maintenance and service checks for operability or running condition; and
- (C) Meets the performance requirements for tanks in 10 CSR 26-2.043 or for piping in 10 CSR 26-2.044, with any performance claims and their manner of determination described in writing by the equipment manufacturer or installer. In addition, all release detection methods must be capable of detecting the leak rate or quantity specified for that tank method in 10 CSR 26-2.043 or piping method in 10 CSR 26-2.044 with a probability of detection of ninety-five percent (95%) and a probability of false alarm of five percent (5%).
- (D) All release detection methods and equipment must be conducted and operated in accordance with the applicable National Work Group on Leak Detection Evaluations (NWGLDE) certification, unless otherwise approved by the department. To obtain copies of equipment certifications, contact the National Work Group for Leak Detection Evaluations, www.nwglde.org.
- (2) When a release detection method for tanks in 10 CSR 26-2.043 or for piping in 10 CSR 26-2.044 indicates a release may have occurred, owners and operators must notify the department in accordance with 10 CSR 26-2.050–10 CSR 26-2.053.
