Wisconsin Administrative Code › Department of Natural Resources › NR 800 - Environmental Protection - Water Supply › Chapter NR 820 - Groundwater Quantity Protection › Subchapter III - Environmental Review of High Capacity Well Applications › Section NR 820.30 - High capacity wells in groundwater protection areas

Current through June 24, 2024
(1) Except as
				  provided in sub. (2), an application for approval of a high capacity well
				  within a groundwater protection area shall be supplemented to include all of
				  the following information:
(a) The name of
				  each class 1, 2 or 3 trout stream, outstanding resource water or exceptional
				  resource water that is located within 1,200 feet of the proposed well location.
Note:
Outstanding resource waters and
					 exceptional resource waters are identified in ss.
					 NR
					 102.10 and
					 102.11. Chapter
					 NR 102 is available for viewing
					 and printing on the Internet at:
					 http://www.legis.state.wi.us/rsb/code/nr/nr102.pdf. Paper copies of ch. NR 102
					 may be obtained from the Department of Natural Resources, Bureau of Watershed
					 Management, 101 South Webster Street, Natural Resources Building, PO Box 7921,
					 Madison, Wisconsin 53707-7921.
(b) The distance from each proposed high
				  capacity well to the class 1, 2 or 3 trout stream, outstanding resource water
				  or exceptional resource water.
(c)
				  If the potentially affected water body is a stream, a description of the stream
				  channel at the point nearest to the proposed well location including stream
				  width, depth of water, publicly available information regarding seasonal flow
				  and nature of the substrate.
(d) If
				  the potentially affected water body is a lake or flowage, a description of the
				  lake or flowage including identification and approximate flows of major inlets
				  and outlets, surface area of the lake or flowage, approximate elevation of the
				  current lake or flowage level, analysis of publicly available information
				  pertaining to historic lake level fluctuations, and nature of the lake
				  bed.
(e) A description of all other
				  wells on the high capacity property including location relative to the class 1,
				  2 or 3 trout stream, or outstanding or exceptional resource water, maximum
				  pumping capacity, estimated actual annual pumpage for each well and frequency
				  of pumping for each well.
(f) A
				  description of the hydrogeologic conditions in the vicinity of the proposed
				  well including flow direction, groundwater elevation, depth to groundwater, and
				  a description of the aquifer characteristics including approximate thickness of
				  each aquifer.
(g) A discussion and
				  analysis of alternative well locations and feasibility of siting the high
				  capacity well outside of the groundwater protection area.
(h) A determination by a registered
				  professional engineer, registered professional geologist or registered
				  professional hydrologist of the 80% exceedance flow for the stream and
				  associated water level at the location closest to the proposed well
				  location.
(i) If the affected water
				  body is a lake, a determination by a registered professional engineer,
				  registered professional geologist or registered professional hydrologist of the
				  80% exceedance flow and associated water level for the primary surface water
				  outlet and the invert elevation of the primary surface water outlet.
(j) The appropriate consumptive use
				  coefficient.
