Current through June 24, 2024
(1) GROUNDWATER
				QUALITY.
(a)
Applicability.
Notwithstanding the applicability provisions of s.
				NR
				140.03, under the authority of ss.
				293.15(11)
				and
				293.66,
				Stats., mining waste facilities regulated under this chapter and other
				facilities situated on a prospecting site regulated under ch. NR 131 or a
				mining site regulated under ch. NR 132, shall comply with the groundwater
				quality standards specified in ch. NR 140 as implemented in this
				section.
(b)
Design
				management zones.
1. The horizontal
				distance to the boundary of the design management zone for mining waste
				facilities regulated under this chapter shall be 1,200 feet from the limits of
				filling, unless reduced under s.
				NR
				140.22(3), or at the boundary of
				property owned or leased by the applicant, whichever distance is
				less.
2. The horizontal distance to
				the boundary of the design management zone for a surface mine or surface
				prospecting excavation shall be 1,200 feet from the edge of the mine or
				prospecting excavation, unless reduced under s.
				NR
				140.22(3), or at the boundary of
				property owned or leased by the applicant, whichever distance is
				less.
3. The horizontal distance to
				the boundary of the design management zone for an underground mine or
				prospecting excavation shall be 1,200 feet from the maximum outer edge of the
				underground prospecting or mine workings adjacent to the ore body as projected
				to the land surface, unless reduced pursuant to s.
				NR
				140.22(3), or at the boundary of
				property owned or leased by the applicant, whichever distance is
				less.
4. The horizontal distance to
				the boundary of the design management zone for facilities, other than the
				prospecting excavation, mine, and mining waste facility, situated on a
				prospecting site regulated under ch. NR 131 or a mining site regulated under
				ch. NR 132, shall be as specified in Table 4 of ch. NR 140, if listed, or 150
				feet from the edge of the facility, unless expanded or reduced under s.
				NR
				140.22(3), or at the boundary of
				property owned or leased by the applicant, whichever distance is
				less.
(c)
Depth
				of useable groundwater.
1. For
				facilities located on a mining or prospecting site or any activity that will
				take place under a mining or prospecting permit or under another approval
				related to a mining or prospecting operation, the department shall determine
				the depth of useable groundwater.
2. For an activity regulated under a mining
				or prospecting permit or another approval related to the mining or prospecting
				operation, the department may not apply a groundwater enforcement standard at
				any point that is deeper than the depth of useable
				groundwater.
(d)
Mandatory intervention boundary.
The horizontal distance to
				the mandatory intervention boundary for a mining waste facility or a surface or
				underground mine or prospecting excavation shall be 150 feet from the limits of
				filling, the outer edge of the mine or prospecting excavation, or the outer
				edge of the underground workings as projected vertically to the land surface,
				unless the boundary of the design management zone is within 300 feet of the
				outer waste boundary, mine, prospecting excavation, or underground prospecting,
				or mine workings. In no case may the mandatory intervention boundary extend
				more than one half the distance from the limits of filling, mine, prospecting
				excavation, or underground prospecting or mine workings to the boundary of the
				design management zone. The mandatory intervention boundary shall apply as
				provided in subs. (1s) and (1u).
