NR 667.0196(1)(c)(c) An equivalent device. Maintain documentation of equivalency at the facility. NR 667.0196(2)(a)(a) Designed or operated to contain 100 percent of the capacity of the largest tank within its boundary. NR 667.0196(2)(b)(b) Designed or operated to prevent run-on or infiltration of precipitation into the secondary containment system unless the collection system has sufficient excess capacity to contain run-on or infiltration. The additional capacity shall be sufficient to contain precipitation from a 25-year, 24-hour rainfall event. NR 667.0196(2)(d)(d) Designed and installed to surround the tank completely and to cover all surrounding earth likely to come into contact with the waste if the waste is released from the tank or tanks (that is, capable of preventing lateral as well as vertical migration of the waste). NR 667.0196(3)(a)(a) Designed as an integral structure (that is, an inner tank completely enveloped within an outer shell) so that any release from the inner tank is contained by the outer shell. NR 667.0196(3)(b)(b) Protected, if constructed of metal, from both corrosion of the primary tank interior and of the external surface of the outer shell. NR 667.0196(3)(c)(c) Provided with a built-in continuous leak detection system capable of detecting a release within 24 hours. NR 667.0196 HistoryHistory: CR 16-007: cr. Register July 2017 No. 739, eff. 8-1-17. NR 667.0197NR 667.0197 What are the requirements for ancillary equipment? Provide ancillary equipment with secondary containment (for example, trench, jacketing double-walled piping) that meets the requirements of s. NR 667.0195, except for: NR 667.0197(1)(1) Above ground piping (exclusive of flanges, joints, valves, and other connections) that are visually inspected for leaks on a daily basis. NR 667.0197(2)(2) Welded flanges, welded joints, and welded connections that are visually inspected for leaks on a daily basis. NR 667.0197(3)(3) Seal less or magnetic coupling pumps and seal less valves, that are visually inspected for leaks on a daily basis. NR 667.0197(4)(4) Pressurized above ground piping systems with automatic shut-off devices (for example, excess flow check valves, flow metering shutdown devices, loss of pressure actuated shut-off devices) that are visually inspected for leaks on a daily basis.

NR 667.0198(1)(1) You may not place hazardous wastes or treatment reagents in a tank system if they could cause the tank, its ancillary equipment or the containment system to rupture, leak, corrode, or otherwise fail. NR 667.0198(2)(2) Use appropriate controls and practices to prevent spills and overflows from tank or containment systems. These include, at a minimum: NR 667.0198(2)(a)(a) Spill prevention controls (for example, check valves, dry disconnect couplings). NR 667.0198(2)(b)(b) Overfill prevention controls (for example, level sensing devices, high level alarms, automatic feed cutoff, or bypass to a standby tank). NR 667.0198(2)(c)(c) Sufficient freeboard in uncovered tanks to prevent overtopping by wave or wind action or by precipitation. NR 667.0198 HistoryHistory: CR 16-007: cr. Register July 2017 No. 739, eff. 8-1-17. NR 667.0199NR 667.0199 What inspection requirements shall I meet? Comply with the following requirements for scheduling, conducting, and documenting inspections. NR 667.0199(1)(1) Develop and follow a schedule and procedure for inspecting overfill controls.
