Current through August 26, 2024

The feasibility report shall contain a proposed preliminary design based on conclusions outlined in the design constraints section of the feasibility report and in accordance with ch. NR 504.

(1) PRELIMINARY DESIGN REPORT. At a minimum, this portion of the narrative section of the feasibility report shall include the following information:

(a) Preliminary materials balance calculations for the necessary volume of clay to construct the liner and final cap of the first phase of the landfill.

(b) Proposed methods for leachate and gas control including collection, containment and treatment.

(c) Proposed operating procedures including the general sequence of filling.

(d) A description of the proposed groundwater, leachate, surface water, gas, air, unsaturated zone and other monitoring programs to be implemented to meet the requirements of chs. NR 140 and 507 and a sampling plan for all monitoring devices in accordance with s. NR 507.16.

(e) Proposed methods for storm water control in accordance with ch. NR 216 and visual screening.

(f) Proposed final use.

(2) PRELIMINARY ENGINEERING PLANS. The preliminary engineering design shall be presented on 24 inch x 36 inch plan sheets. A maximum 5 foot contour interval shall be used for required drawings, unless an alternate size or interval is approved by the department in writing. Plan sheets shall be prepared as follows:

(a) The existing conditions map shall be used to show the proposed access, limits of filling, internal roads, load-out and scale facilities, associated buildings, storm water diversions, sedimentation basins, phases of facility development, sub-base and base grades, slopes and the leachate collection system including the location of any proposed leachate storage tank, lift station or sewer hook up.

(b) The present topography, proposed sub-base, base and final grades, and the liner and final cap configurations shall be displayed on all geologic cross-sections intersecting the proposed limits of filling.

(c) A plan sheet showing the proposed closure sequence and final grades.
