Spill and Overfill Control for In-Use Underground Storage Tank Systems

PURPOSE: This rule is designed to prevent releases during routine filling of the underground storage tank with product. PUBLISHER’S NOTE: The secretary of state has determined that the publication of the entire text of the material which is incorporated by reference as a portion of this rule would be unduly cumbersome or expensive. This material as incorporated by reference in this rule shall be maintained by the agency at its headquarters and shall be made available to the public for inspection and copying at no more than the actual cost of reproduction. This note applies only to the reference material. The entire text of the rule is printed here. (1) Owners and operators must ensure that releases due to spilling or overfilling do not occur. The owner and operator must ensure that the volume available in the tank is greater than the volume of product to be transferred to the tank before the transfer is made and that the transfer operation is monitored constantly to prevent overfilling and spilling. (2) The owner and operator must report, investigate, and clean up any spills and overfills in accordance with 10 CSR 26-2.053. (3) Owners and operators must meet one (1) Substance Storage Tanks of the following requirements to ensure their spill prevention equipment is operating properly and will prevent releases to the environment: (A) Have double-walled spill prevention equipment and monitor the space between the walls at least once every thirty (30) days; or (B) The spill prevention equipment is tested at least triennially to ensure the spill prevention equipment is liquid tight by using vacuum, pressure, or liquid testing in accordance with one (1) of the following: 1. Requirements developed by the manufacturer (Note: This option may only be used if the manufacturer has developed testing requirements. Self-testing apparatus may only be used if pre-approved by the department as a valid functionality test.); or 2. Interstitial test (for double-walled spill basins only) or spill containment test listed by the National Work Group on Leak Detection Evaluations.

Other methods approved by the department, which may include a code of practice developed by a nationally recognized association or independent testing laboratory, determined to be no less protective of human health and the environment than the requirements listed in paragraphs 1. through 3. of this subsection. (4) Spill basins may not be repaired with a partial or spot, field-applied repair kit or product. Repairs must either be a manufacturer-designed replacement insert or a complete factory-built, field-installed spill basin repair kit. Other repairs may be approved by the department if they are determined to be no less protective of human health and the environment. (5) Owners and operators must ensure their overfill prevention equipment is operating properly and will prevent releases to the environment. Overfill prevention equipment must be inspected or tested at least triennially. At a minimum, the test or inspection must ensure that overfill prevention equipment is set to activate at the correct level specified in 10 CSR 26-2.020 and will activate when the regulated substance reaches that level. Tests or inspections must be conducted in accordance with one (1) of the following criteria: (A) Requirements developed by the manufacturer, but only if the test or inspection confirms that all portions of the overfill device are intact and functional. (Note: This option may be used if the manufacturer has developed testing requirements. Self-testing apparatus may only be used if approved by the department as a valid functionality test); or (B) Petroleum Equipment Institute RP 1200-12, Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities.

(6) The first test of the spill equipment and the first test or inspection of the overfill prevention equipment required by this rule is due no later than January 1, 2020. (7) If a tank has been out of use for more than twelve (12) months, equipment must be confirmed operational with a test of the spill prevention equipment and an inspection or test of the overfill prevention equipment, prior to bringing it back in-use. (8) Owners and operators must maintain the following records, in accordance with 10 CSR 26-2.034, for spill and overfill prevention equipment: (A) Test and/or inspection records must be maintained for three (3) years; and/or (B) When using interstitial monitoring, records must be maintained for twelve (12) months.
