Current through June 24, 2024
(1) No person may establish or construct a
				mining waste site or expand an existing mining waste site until a plan of
				operation has been submitted to the department in accordance with this section
				and approved in writing by the department. No person may establish, construct,
				operate, maintain, close, provide long-term care for, or terminate a mining
				waste facility except in accordance with the approved plan of operation. The
				plan of operation shall be prepared and submitted to the department in
				accordance with s. NR 182.104. The plan of operation shall be submitted at the
				same time as the permit application and plans submitted under ch. NR 131 or 132
				and shall be consistent with the applications and plans submitted under ch. NR
				131 or 132. For new facilities on permitted mining or prospecting sites, a
				person may submit a plan of operation with the feasibility report or at any
				time after the feasibility report is submitted. No person may submit a plan of
				operation for a facility prior to the time the person submits a feasibility
				report to the department for that facility. If the proposed waste site is a
				surface mine backfilled with mining waste, a person may satisfy the
				requirements for submitting the plan of operation under this section by
				including the information required by this section in the mining permit
				application submitted to the department under ch. NR 132 and issuance by the
				department of the mining permit shall constitute approval of the plan of
				operation requirements.
(2) All
				plans of operation for waste sites shall be consistent with the feasibility
				report and mining permit application for the waste site and shall contain
				detailed plans and specifications necessary for the construction, operation,
				closure, long-term care and termination of the project. All information shall
				be presented in a clear and understandable manner. The plan of operation shall
				contain all of the following information:
(a)
				A set of engineering plans drawn on standard 24-inch by 36-inch plan sheets. If
				facility details cannot be shown on standard plan sheets at a 1:100 scale, the
				engineering plans may be drawn on 30-inch by 42-inch plan sheets. All plan
				sheets except the title sheet, existing conditions sheet, cross-sections, and
				details sheets shall utilize the existing conditions sheet as a base map. For
				complex plans, existing conditions within the mining waste facility area may be
				shown by lighter lines or may be eliminated. All plan sheets shall also be
				submitted in digital form using appropriate geographic information system
				format. The engineering plans shall include all of the following:
1. A title sheet that indicates the project
				title, who prepared the plans, the date the plans were prepared, the applicant
				for whom the plans were prepared, a table of contents, a map showing the
				location of the facility relative to the other mining project facilities, the
				location of the facility within the county or multicounty area, and the
				location of the county or multicounty area within the state.
2. An existing conditions plan consisting of
				a detailed topographic map of the proposed facility and all areas within 1,500
				feet of the proposed limits of filling prior to development. The minimum scale
				shall be 1" = 200 feet with a maximum 2-foot contour interval. The contour
				interval selected shall be sufficiently small to clearly show surface water
				flow patterns within and around the facility. All elevations shall be related
				to USGS datum. The existing conditions plan shall identify and define all of
				the following:
a. The surface waters including
				intermittent and ephemeral streams and wetlands.
b. The property boundaries, the proposed
				waste facility boundary, and the proposed limits of filling.
c. A north arrow, mining waste facility
				survey grid, a formula for converting grid locations to the state plane
				coordinate system, and the locations of all existing and proposed survey
				monuments.
d. Any nearby
				residential and commercial structures and other buildings.
e. The locations of all soil borings, all
				existing and abandoned groundwater monitoring wells, all public and private
				water supply wells, and the general locations of all known septic system drain
				fields within 1,000 feet of the mining waste facility or within 500 feet of any
				monitoring well.
f. Any utility
				lines, underground pipelines and electrical lines, access control, and other
				constructed topographic and drainage features.
3. Plan sheets that depict the sub-base
				grades, all sub-base appurtenances, such as lysimeters or drain pipes, and the
				base grades.
4. Separate plan
				sheets that depict the overall mining waste facility area and the limits of
				liner construction and filling. The plan sheets shall depict the layout and
				slope of the liner system and leachate collection system including pipes,
				sumps, riser pipes on interior sideslopes, manholes, trenches, berms, lift
				stations, permanent storm water control structures, pipe cleanouts, and other
				pertinent structures. Invert elevations shall be provided at any changes in
				grade for all leachate and groundwater collection and transfer
				systems.
5. A series of phasing
				plan sheets that show facility development through time. The location of
				peripheral features such as support buildings, access roads, drainage ditches,
				sedimentation basins, any other storm water management features, and screening
				berms shall be indicated on this plan. At a minimum, the engineering plan shall
				provide a separate plan sheet for initial construction and for each subsequent
				phase of development or new area where substantial construction is to be
				performed. These subsequent phasing plan sheets shall present the final filling
				surfaces in the previous phases of development; the limits of clearing,
				grubbing, and topsoil removal; the base grades of the new phase of filling; the
				anticipated surface contours of soil stockpiles at the time depicted on the
				plan sheet; and storm water management features. Each plan shall include a list
				of construction items and quantities necessary to prepare the phase of
				development indicated on the plan.
6. Plan sheets that depict the features to be
				constructed for storm water management at the time of initial construction,
				during phased development, and after closure of the mining waste facility. Plan
				sheets shall include the locations of sediment basins, drainage ditches,
				auxiliary sediment traps, and the anticipated extent of cleared ground and
				stockpiles during each major phase of facility development. Plan sheets shall
				include a list of anticipated actions and materials needed for sediment and
				erosion control.
7. A final waste
				grades plan sheet that indicates waste final grades. The engineering plan shall
				include a final topography plan sheet to indicate the condition of the entire
				facility following closure including storm water drainage features and the
				location of all other penetrations of the final cover, if applicable.
8. A facility monitoring plan that shows the
				location of the design management zone as determined under s. NR 182.107 and
				all devices for the monitoring of leachate quality and quantity, unsaturated
				zone water quality and flow rate, groundwater quality, storm water quality, and
				surface settlement.
9. A long-term
				care plan sheet that shows the topography of site at the completion of closure.
				This plan sheet shall include a table identifying those items anticipated to be
				performed during the period of long-term care for the site including the
				proposed schedule for monitoring and maintenance of the facility. The applicant
				may include the information in this subdivision in the final site topography
				plan sheet if clarity is not compromised, or reference may be made to the
				appropriate section of the operations manual and design report.
10. Detailed plan review sheets that show a
				minimum of 2 cross-sections in each direction drawn perpendicular and parallel
				to the facility baseline through the major dimensions of the facility. The
				applicant shall illustrate the location of the cross-sections using a reduced
				scale plan view on each cross-section. Each combined engineering and geologic
				cross-section shall show all of the following:
a. Existing grades.
b. Sub-base, base, top of leachate collection
				blanket grades, and final grades.
c. Soil borings and monitoring wells that the
				depicted cross-section passes through or that are adjacent to the
				cross-section.
d. Soil and bedrock
				types. For clarity, a number or symbol shall be used to label major soil units
				instead of extensive shading.
e.
				Stabilized water table contours.
f.
				Leachate collection and monitoring systems.
