Universal Citation: WI Admin Code § NR 670.017

Current through August 26, 2024

Except as otherwise provided in s. NR 664.0001, owners and operators of facilities that store, treat or dispose of hazardous waste in surface impoundments shall provide all of the following additional information:

(1)A list of the hazardous wastes placed or to be placed in each surface impoundment.

(2)Detailed plans and an engineering report describing how the surface impoundment is designed and is or will be constructed, operated and maintained to meet ss. NR 664.0019, 664.0221, 664.0222 and 664.0223, addressing all of the following items:

(a) The liner system (except for an existing portion of a surface impoundment). If an exemption from the requirement for a liner is sought as provided by s. NR 664.0221(2), submit detailed plans and engineering and hydrogeologic reports, as appropriate, describing alternate design and operating practices that will, in conjunction with location aspects, prevent the migration of any hazardous constituents into the groundwater or surface water at any future time.

(b) The double liner and leak (leachate) detection, collection and removal system, if the surface impoundment shall meet s. NR 664.0221(3). If an exemption from the requirements for double liners and a leak detection, collection, and removal system or alternative design is sought as provided by s. NR 664.0221(4), (5) or (6), submit appropriate information.

(c) If the leak detection system is located in a saturated zone, submit detailed plans and an engineering report explaining the leak detection system design and operation, and the location of the saturated zone in relation to the leak detection system.

(d) The construction quality assurance (CQA) plan if required under s. NR 664.0019.

(e) Proposed action leakage rate, with rationale, if required under s. NR 664.0222, and response action plan, if required under s. NR 664.0223.

(f) Prevention of overtopping.

(g) Structural integrity of dikes.

(3)A description of how each surface impoundment, including the double liner system, leak detection system, cover system and appurtenances for control of overtopping, will be inspected in order to meet s. NR 664.0226(1), (2) and (4). This information shall be included in the inspection plan submitted under s. NR 670.014(2) (e).

(4)A certification by a qualified engineer which attests to the structural integrity of each dike, as required under s. NR 664.0226(3). For new units, the owner or operator shall submit a statement by a qualified engineer that the engineer will provide such a certification upon completion of construction according to the plans and specifications.

(5)A description of the procedure to be used for removing a surface impoundment from service, as required under s. NR 664.0227(2) and (3). This information shall be included in the contingency plan submitted under s. NR 670.014(2) (g).

(6)A description of how hazardous waste residues and contaminated materials will be removed from the unit at closure, as required under s. NR 664.0228(1) (a). For any wastes not to be removed from the unit upon closure, the owner or operator shall submit detailed plans and an engineering report describing how s. NR 664.0228(1) (b) and (2) will be complied with. This information shall be included in the closure plan and, where applicable, the long-term care plan submitted under s. NR 670.014(2) (m).

(7)If ignitable or reactive wastes are to be placed in a surface impoundment, an explanation of how s. NR 664.0229 will be complied with.

(8)If incompatible wastes, or incompatible wastes and materials will be placed in a surface impoundment, an explanation of how s. NR 664.0230 will be complied with.

(9)A waste management plan for hazardous waste numbers F020, F021, F022, F023, F026 and F027 describing how the surface impoundment is or will be designed, constructed, operated and maintained to meet s. NR 664.0231. This submission shall address all of the following items specified in s. NR 664.0231:

(a) The volume, physical and chemical characteristics of the wastes, including their potential to migrate through soil or to volatilize or escape into the atmosphere.

(b) The attenuative properties of underlying and surrounding soils or other materials.

(d) The effectiveness of additional treatment, design or monitoring techniques.

(10)Information on air emission control equipment as required in s. NR 670.027.
