Wis. Admin. Code Department of Natural Resources NR 661.0196

Current through October 28, 2024
Section NR 661.0196 - Response to leaks or spills and disposition of leaking or unfit-for-use tank systems

A tank system or secondary containment system from which there has been a leak or spill, or which is unfit for use, shall be removed from service immediately, and the remanufacturer or other person that stores or treats the hazardous secondary material shall satisfy all of the following requirements:

(1) CESSATION OF USE; PREVENT FLOW OR ADDITION OF MATERIALS. The remanufacturer or other person that stores or treats the hazardous secondary material shall immediately stop the flow of hazardous secondary material into the tank system or secondary containment system and inspect the system to determine the cause of the release.
(2) REMOVAL OF MATERIAL FROM TANK SYSTEM OR SECONDARY CONTAINMENT SYSTEM.
(a) If the release was from the tank system, the remanufacturer or other person that stores or treats the hazardous secondary material shall, within 24 hours after detection of the leak or, if the remanufacturer or other person that stores or treats the hazardous secondary material demonstrates that it is not possible, at the earliest practicable time, remove as much of the material as is necessary to prevent further release of hazardous secondary material to the environment and to allow inspection and repair of the tank system to be performed.
(b) If the material was released to a secondary containment system, all released materials shall be removed within 24 hours or in as timely a manner as is possible to prevent harm to human health and the environment.
(3) CONTAINMENT OF VISIBLE RELEASES TO THE ENVIRONMENT. The remanufacturer or other person that stores or treats the hazardous secondary material shall immediately conduct a visual inspection of the release and, based upon that inspection do all of the following:
(a) Prevent further migration of the leak or spill to soils or surface water.
(b) Remove and properly dispose of any visible contamination of the soil or surface water.
(4) NOTIFICATIONS, REPORTS.
(a) Except as provided in par. (b), any release to the environment shall be reported to the department within 24 hours of its detection. If the release has been reported pursuant to ch. NR 706, that report will satisfy this requirement.
(b) A person need not report on a leak or spill of a hazardous secondary material in any of the following circumstances:
1. The leak or spill is less than or equal to a quantity of one pound.
2. The leak or spill is immediately contained and cleaned up.
(c) Within 30 days of detection of a release to the environment, a report containing all of the following information shall be submitted to the department:
1. The likely route of migration of the release.
2. The characteristics of the surrounding soil, such as soil composition, geology, hydrogeology, and climate.
3. The results of any monitoring or sampling conducted in connection with the release, if available. If sampling or monitoring data relating to the release are not available within 30 days, these data shall be submitted to the department as soon as they become available.
4. The proximity to downgradient drinking water, surface water, and populated areas.
5. The description of response actions taken or planned.
(5) PROVISION OF SECONDARY CONTAINMENT, REPAIR, OR CLOSURE.
(a) Unless the remanufacturer or other person that stores or treats the hazardous secondary material satisfies the requirements specified in pars. (b) to (d), the tank system shall cease to operate under the remanufacturing exclusion under s. NR 661.0004(1) (za).
(b) If the cause of the release was a spill that has not damaged the integrity of the system, the remanufacturer or other person that stores or treats the hazardous secondary material may return the system to service as soon as the released material is removed and any necessary repairs are made.
(c) If the cause of the release was a leak from the primary tank system into the secondary containment system, the system shall be repaired prior to returning the tank system to service.
(d) If the source of the release was a leak to the environment from a component of a tank system without secondary containment, the remanufacturer or other person that stores or treats the hazardous secondary material shall provide the component of the system from which the leak occurred with secondary containment that satisfies the requirements specified in s. NR 661.0193 before it can be returned to service, unless the source of the leak is an aboveground portion of a tank system that can be inspected visually. If the source is an aboveground component that can be inspected visually, the component shall be repaired and may be returned to service without secondary containment as long as the requirements under sub. (6) are satisfied. Additionally, if a leak has occurred in any portion of a tank system component that is not readily accessible for visual inspection, such as the bottom of an inground or onground tank, the entire component shall be provided with secondary containment as specified in s. NR 661.0193 prior to being returned to use.
(6) CERTIFICATION OF MAJOR REPAIRS. If the remanufacturer or other person that stores or treats the hazardous secondary material has repaired a tank system in accordance with sub. (5), and the repair has been extensive, such as installation of an internal liner or repair of a ruptured primary containment or secondary containment vessel, the tank system may not be returned to service unless the remanufacturer or other person that stores or treats the hazardous secondary material has obtained a certification by a qualified professional engineer that the repaired system is capable of handling hazardous secondary material without release for the intended life of the system. This certification shall be kept on file at the facility and maintained until closure of the facility.
