In addition, failure to comply with any condition of an approval or the construction, reconstruction or operation of any well or water system in violation of any statute, rule or department order shall void the approval. Approval is required for all of the following:
NR 812.09(4)(a) (a) The construction, reconstruction, or operation of a high capacity well or high capacity well system, including dewatering wells, school wells, and wastewater treatment plant wells, except those actions specified in s. 281.34 (2g), Stats. An application for a high capacity well or high capacity well system approval shall include, for every well, the location, construction or reconstruction features, pump installation features, the proposed rate of operation and the distance to nearby public utility wells, as defined in s. 196.01, Stats. A high capacity well or high capacity well system approval is subject to all of the following:
NR 812.09(4)(a)1. 1. The department may deny approval, grant a limited approval or modify an approval under which the location, depth, pumping capacity or rate of flow and ultimate use is restricted so that the supply of water for any public utility, as defined by s. 196.01, Stats., will not be impaired. Reduced availability of groundwater to a public utility well may be indicated when calculated drawdown, using estimated values for aquifer characteristics, results in a reduction of 10% or greater in the public water utility's saturated thickness based on pumping from the proposed high capacity well or well system. The department may also deny approval or condition an approval if the proposed or actual well location, water quality, well construction or pump installation features or the use of the well does not meet, at the time of application, the specifications of this chapter for new well construction and pump installation or water use.
NR 812.09(4)(a)2. 2. When an owner transfers the land on which a high capacity well or high capacity well system is located, the owner shall provide notice to the department as specified in s. 281.34 (2g) (c), Stats.

NR 812.09(4)(a)4. 4. Emergency approval for a high capacity well or high capacity well system may be granted when fire hazard, imminent crop damage or other similar emergency requires expedited approval, if the owner submits the request in writing with a justification of the emergency, and if the department determines that the high capacity well or high capacity well system meets the requirements of s. 281.34 (5), Stats.
