NR 815.12 Visitorial powers of the department. NR 815.01NR 815.01 Purpose. The purpose of this chapter is to establish uniform minimum standards and methods in conformity with s. 281.17 (8), Stats., for the following: NR 815.01(1)(1) Construction or use of a well for the purpose of placing a fluid underground. NR 815.01(2)(2) Protection of underground sources of drinking water, aquifers and groundwater from contamination that may occur as a result of the use of an injection well. NR 815.01 HistoryHistory: CR 01-104: cr. Register October 2004 No. 586, eff. 11-1-04. NR 815.02NR 815.02 Applicability.

Injection wells that are governed by this chapter include, but are not limited to: NR 815.02(1)(a)(a) Any injection well on a drilling platform that is located within the jurisdictional boundaries of the state. NR 815.02(1)(b)(b) Except as provided in sub. (2), any well that is constructed or used to place a fluid underground. NR 815.02(1)(c)(c) Any well used by a generator of hazardous waste, or by the owner or operator of a hazardous waste management facility, to dispose of a fluid containing hazardous waste. This includes the disposal of hazardous waste into a waste disposal system that would otherwise be a septic system or cesspool regardless of the capacity of the waste disposal system. NR 815.02(1)(d)(d) Any septic system, cesspool or other well that is used by a multiple-family dwelling, multiple dwellings, community system or regional system to place a fluid underground. NR 815.02(2)(2) Specific exclusions. The following are not governed by this chapter: NR 815.02(2)(a)(a) Any injection well on a drilling platform or other site that is located in its entirety beyond the jurisdictional boundaries of the state. NR 815.02(2)(b)(b) Any private onsite wastewater treatment system approved according to the provisions of ch. SPS 383 that is used to dispose of sanitary waste from an individual single-family dwelling. NR 815.02 HistoryHistory: CR 01-104: cr.
