Missouri Code of State Regulations › Title 10 - DEPARTMENT OF NATURAL RESOURCES › Division 26 - Petroleum and Hazardous Substance Storage Tanks › Chapter 2 - Underground Storage Tanks-Technical Regulations › Section 10 CSR 26-2.040 - General Requirements for Release Detection for All Underground Storage Tank Systems

Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: There are two (2) primary purposes for this
				  rulemaking. The first is to open UST rules in Title 10, Division 26 of the Code
				  of State Regulations to make the necessary changes required by the U.S.
				  Environmental Protection Agency (EPA). The 2005 Energy Policy Act required
				  either financial responsibility for UST installers and manufacturers or
				  secondary containment for all new systems. In addition, last October, EPA
				  adopted changes to the federal UST regulations that need to be incorporated
				  into state regulation. This rule-making will make the necessary changes to
				  comply with these EPA grant requirements and to incorporate the changes made to
				  the federal regulations.
The second reason is to incorporate state-specific
				  changes. The proposed changes would better ensure that old tanks are still
				  functional enough to remain in use. The changes would better prevent and detect
				  leaks and incorporate new technologies. The department will also take this
				  opportunity to clarify ambiguous or confusing language and update industry
				  standard referenced in the regulations.
(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, tested, and maintained in accordance with the
				manufacturer's instructions, including routine maintenance and service checks
				for operability or running condition. If manufacturer's test methods are not
				available, the annual operability test may be conducted in accordance with a
				code of practice developed by a nationally recognized association or
				independent testing laboratory or a method approved by the department.
				Operability test reports must, at a minimum, include facility name and address,
				components tested, model and serial number (if legible), testing date, test
				method, technician name and affiliation, and a certification of
				results;
(C) For existing sites,
				the first test is due not later than January 1, 2020. Electronic and mechanical
				release detection equipment must be tested annually for proper operation, in
				accordance with subsection (B) of this section. A test of the proper operation
				must be performed at least annually and, at a minimum and as applicable to the
				facility, cover the following components and criteria:
1. Automatic tank gauge and other
				controllers: test alarm; verify system configuration; test battery
				backup;
2. Probes and sensors:
				inspect for residual buildup; ensure floats move freely; ensure shaft is not
				damaged; ensure cables are free of kinks, bends, and breaks; test alarm
				operability and communication with controller; and
3. Vacuum pumps and pressure gauges: ensure
				proper communication with sensors and controller;
(D)
				Meets the performance requirements for tanks in
				10 CSR
				26-2.043 or 10 CSR 26-2.046 for field constructed
				tanks, or for piping in 10 CSR 25-2.044 or 10 CSR 26-2.047 for bulk piping,
				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 the method in
				10 CSR
				26-2.043,
				10 CSR
				26-2.044, 10 CSR 26-2.046, or 10 CSR 26-2.047, as
				appropriate, with a probability of detection of ninety-five percent (95%) and a
				probability of false alarm of five percent (5%); and
(E) All release
				detection methods and equipment must be conducted and operated in accordance
				with the applicable National Work Group on Leak Detection Evaluations listing,
				unless otherwise approved by the department. To obtain copies of equipment
				listings, contact the National Work Group on Leak Detection Evaluations,
