NR 667.0173(1)(1) Design and operate a containment system for your container storage areas according to the requirements in sub. (2), except as otherwise provided by sub. (3)

NR 667.0173(2)(2) The design and operating requirements for a containment system are:

NR 667.0173(2)(a)(a) A base shall underlie the containers that is free of cracks or gaps and is sufficiently impervious to contain leaks, spills and accumulated precipitation until the collected material is detected and removed.

NR 667.0173(2)(b)(b) The base shall be sloped, or the containment system shall be otherwise designed and operated to drain and remove liquids resulting from leaks spills, or precipitation, unless the containers are elevated or are otherwise protected from contact with accumulated liquids.

NR 667.0173(2)(c)(c) The containment system shall have sufficient capacity to contain 10% of the volume of containers, or the volume of the largest container, whichever is greater. This requirement does not apply to containers that do not contain free liquids.

NR 667.0173(2)(d)(d) Prevent run-on into the containment system unless the collection system has sufficient excess capacity, in addition to that required in par. (c), to contain the liquid.

NR 667.0173(2)(e)(e) Remove any spilled or leaked waste and accumulated precipitation from the sump or collection area as promptly as is necessary to prevent overflow of the collection system.

NR 667.0173(3)(3) Except as provided in sub. (4), you do not need a containment system as defined in sub. (2) for storage areas that store containers holding only wastes with no free liquids, if either:

NR 667.0173(3)(a)(a) The storage area is sloped or is otherwise designed and operated to drain and remove liquid resulting from precipitation.

NR 667.0173(3)(b)(b) The containers are elevated or are otherwise protected from contact with accumulated liquid.

NR 667.0173(4)(4) You shall have a containment system defined by sub. (2) for storage areas that store containers holding FO20, FO21, FO22, FO23, FO26, and FO27 wastes, even if the wastes do not contain free liquids.

NR 667.0174NR 667.0174 What special requirements shall I meet for ignitable or reactive waste? Locate containers holding ignitable or reactive waste at least 15 meters (50 feet) from your facility property line. Follow the general requirements for ignitable or reactive wastes that are specified in s. NR 667.0017 (1).

NR 667.0175(1)(1) You may not place incompatible wastes, or incompatible wastes and materials (see ch. NR 664 Appendix V for examples), in the same container, unless you comply with s. NR 667.0017 (2).

NR 667.0175(2)(2) You may not place hazardous waste in an unwashed container that previously held an incompatible waste or material.

NR 667.0175(3)(3) Separate a storage container holding a hazardous waste that is incompatible with any waste or with other materials stored nearby in other containers, piles, open tanks or surface impoundments from the other materials, or protect the containers by means of a dike, berm, wall or other device.

NR 667.0175 HistoryHistory: CR 16-007: cr. Register July 2017 No. 739, eff. 8-1-17; correction in (1) made under s. 35.17, Stats., Register July 2017 No. 739.

NR 667.0176NR 667.0176 What shall I do when I want to stop using the containers? Remove all hazardous waste and hazardous waste residues from the containment system. Decontaminate or remove remaining containers, liners, bases, and soil containing, or contaminated with, hazardous waste, or hazardous waste residues.

NR 667.0177NR 667.0177 What air emission standards apply? Manage all hazardous waste placed in a container according to the requirements of subchs. AA, BB, and CC of ch. NR 664. Under a standardized license, the following control devices are permissible: Thermal vapor incinerator, catalytic vapor incinerator, flame, boiler, process heater, condenser and carbon absorption unit.

NR 667.0190NR 667.0190 Does this subchapter apply to me? This subchapter applies to you if you own or operate a facility that treats or stores hazardous waste in above-ground or on-ground tanks under a subch. J of ch. NR 667 standardized license, except as provided in s. NR 667.0001 (2).

NR 667.0190(1)(1) You do not have to meet the secondary containment requirements in s. NR 667.0195 if your tank systems do not contain free liquids and are situated inside a building with an impermeable floor. You shall demonstrate the absence or presence of free liquids in the stored or treated waste, using Method 9095B (Paint Filter Liquids Test) as described in “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW–846, as incorporated by reference in s. NR 660.11.

NR 667.0190(2)(2) You do not have to meet the secondary containment requirements of s. NR 667.0195 (1) if your tank system, including sumps, as defined in s. NR 660.10, is part of a secondary containment system to collect or contain releases of hazardous wastes.
