NR 213.06(3)(c)(c) During the 30-day public comment period following public notice by the department of intent to issue, reissue or modify a WPDES permit under s. 283.39, Stats., or NR 213.06(4)(4) Submitting an exemption request-existing structures. The owner or operator of a lagoon, storage structure or treatment structure in existence prior to July 1, 1990 may request an exemption from the design standards and material requirements of this chapter. If an exemption is not granted, the department shall propose to issue a new WPDES permit or modify the existing WPDES permit to include a schedule of compliance to achieve the purpose of this chapter. NR 213.06 HistoryHistory: Cr. Register, June, 1990, No. 414, eff. 7-1-90. NR 213.07NR 213.07 Abandonment. Lagoons, storage structures and treatment structures which will no longer be used, shall be properly abandoned within 2 years of the date on which waste material was last stored or treated. A plan outlining the proposed method of abandonment shall be submitted to the department for approval. This plan shall contain a procedure to properly identify the presence and characteristics of any accumulated solid waste and provide appropriate removal, disposal or recycling or treatment alternatives in accordance with applicable solid and hazardous waste laws. All recycling, treatment and disposal shall be conducted so as to protect public health and the environment. Unless otherwise directed by the department, all abandonment plans shall comply with ch. NR 720 for soils that have been contaminated by the contents of the lagoon, storage structure or treatment structure. The plan shall also address site restoration and any landscaping that will prevent accumulation of standing water or runoff. The department may require groundwater monitoring for a period of time after abandonment of the land treatment system to assess groundwater impacts. The design, installation, construction, abandonment and documentation of all monitoring wells shall be in accordance with the requirements of ch. NR 141. NR 213.07 HistoryHistory: Cr. Register, June, 1990, No. 414, eff. 7-1-90; am., Register, April, 1994, No. 460, eff. 5-1-94; am., Register, March, 1995, No. 471, eff. 4-1-95. NR 213.08NR 213.08 General design requirements. NR 213.08(1)(a)(a) Lagoons, storage structures and treatment structures may not be located closer than: NR 213.08(1)(a)1.1. 1,000 feet from a well serving a community public water supply system. NR 213.08(1)(a)3.3. 500 feet from an inhabited dwelling except that this distance may be reduced with written permission from the owner and occupants of the residence. The department may require a greater distance depending on the type of lagoon, storage structure or treatment structure and potential for aesthetic impacts and public health impacts. NR 213.08(1)(b)(b) Lagoons, storage structures and treatment structures may not be located in the floodway and shall conform with the requirements of ch. NR 116. NR 213.08(1)(c)(c) Lagoons, storage structures and treatment structures may not be located within wetlands. NR 213.08(1)(d)(d) Lagoons, storage structures and treatment structures shall be designed and operated to minimize the level of substances in the groundwater and to prevent exceedance of the groundwater preventive action limits (PAL) to the extent technically and economically feasible. Groundwater preventive action limits are listed in ss. NR 140.10 and 140.12. NR 213.08(2)(a)(a) Effective erosion protection of exterior slopes of lagoons shall be provided by appropriate means, such as riprap or seeding with grass. NR 213.08(2)(b)(b) Lagoons shall be maintained as necessary to prevent scouring of the liner and liner cover, discourage vegetative growth, and avoid desiccation and cracking of the liner. NR 213.08(2)(c)(c) A minimum separation of 5 feet shall be maintained between the bottom of the lagoon liner or subbase of a storage structure and either bedrock or the groundwater level, whichever is higher. NR 213.08(3)(a)(a) A groundwater monitoring system designed and constructed in accordance with ch. NR 141 may be required by the department to provide information on the long term effects of a lagoon, storage structure or treatment structure on groundwater. NR 213.08(3)(b)(b) When a groundwater monitoring system is required, the parameters to be monitored and the monitoring frequency will be established on a case-by-case basis. NR 213.08(4)(4) Additional design requirements. In cases where critical groundwater, geologic or construction conditions warrant, the department may require construction specifications or testing requirements more stringent than those described in this chapter if necessary to preclude detrimental effects to the groundwater.

NR 213.09(1)(1) General. An engineering report and plans and specifications shall be submitted to the department for approval in accordance with s. 281.41, Stats., prior to initiating construction. NR 213.09(1)(a)(a) The department recommends, whenever possible, a preliminary engineering report outlining the project and including any available information required under par. (b) be made prior to submittal of final plans. NR 213.09(1)(b)(b) The engineering report shall outline the entire project and include, at a minimum, the following information: subsurface site conditions, waste sources, waste analysis and waste volume; materials and specifications of the proposed liner required under ss. NR 213.10 and 213.11; compatibility of the waste and proposed liner and estimated life of the liner required under sub. (4); the proposed method of installation, and the equipment and testing methods to be used for quality control both during and after construction.
