and signage.
The reclamation plan and financial assurance shall be provided
to Sauk County as pursuant to § NR 135, Wis. Adm. Code,
and Sauk County Code Chapter 24. Sauk County may require the submittal
of additional information as may be necessary to determine the nature
of the mining operation and proposed reclamation.
For sites with planned excavation lower than the groundwater
table, the operator shall submit a detailed hydrogeological report.
The operator shall be required to reimburse the City for the expense
of professional work or opinions in review of a hydrogeological report
if recommended by staff or the Plan Commission or RADC. The hydrogeological
report shall provide the following information, as well as a description
and justification of all hydrologic methods used:
A. Existing conditions to establish baseline data, including, but not
limited to:
(1)
Analysis of groundwater quality on the mining site consistent
with § NR 140.20, Wis. Adm. Code.
(2)
Identification of all known contaminated groundwater resources
within 1/2 mile of the mining site.
(3)
Identification of all karst features, such as sinkholes, stream
sinks, springs, caves, joints, or fractures, within 1/2 mile of the
mining site.
(4)
Identification and elevation of all surface waters and headwaters
within a minimum of 1/2 mile of the mining site. Elevations must include
the existing water level, as well as the ordinary high-water mark
where applicable.
(5)
Identification of all existing groundwater users (such as neighboring
private water-supply wells, wellhead protection areas, municipal wells,
and irrigation wells) within 1,200 feet of the mining site consistent
with Ch. NR 812, Wis. Adm. Code. Well construction reports, including
well location, well depth, depth of casing, depth to water, and aquifers
penetrated, shall be identified.
