NR 135.09 NR 135.09 Topsoil management.

NR 135.09(1) (1) Removal. Topsoil and topsoil substitute material shall be provided as specified in the reclamation plan in order to achieve reclamation to the approved post-mining land use. Removal of on-site topsoil and topsoil substitute material removal, when specified in the reclamation plan, shall be performed prior to any mining activity associated with any specific phase of the mining operation.

NR 135.09(2) (2) Volume. The operator shall obtain the volume of soil required to perform final reclamation by removal of on-site topsoil or topsoil substitute material or by obtaining topsoil or substitute material as needed to make up the volume of topsoil as specified in the reclamation plan.

NR 135.09 Note Note: Existing resources that may be used to identify the soil present on a site include the County Soil Surveys and information obtained from a soil scientist or the University of Wisconsin Soil Science Extension Agent or other available resources. Topsoil or topsoil substitute material shall be removed from areas to be affected by mining operations to the depth indicated in the reclamation plan or as determined in the field by a soil scientist, project engineer or other qualified professional.

NR 135.09(3) (3) Storage. Once removed, topsoil or topsoil substitute material shall, as required by the reclamation plan, either be used in contemporaneous reclamation or stored in an environmentally acceptable manner. The location of stockpiled topsoil or topsoil substitute material shall be chosen to protect the material from erosion or further disturbance or contamination. Runoff water shall be diverted around all locations in which topsoil or topsoil substitute material is stockpiled.

NR 135.10 NR 135.10 Final grading and slopes.

NR 135.10(1) (1) All areas affected by mining shall be addressed in the approved reclamation plan, pursuant to s. NR 135.19, to provide that a stable and safe condition consistent with the post-mining land use is achieved. The reclamation plan may designate highwalls or other unmined and undisturbed natural solid bedrock as stable and safe and not in need of reclamation or designate other areas affected by mining including slopes comprised of unconsolidated materials that exceed a 3:1 slope, whether or not graded, as stable and safe. For slopes designated as stable under this subsection, the regulatory authority may require that either: a site-specific engineering analysis be performed by a registered professional engineer to demonstrate that an acceptable slope stability factor is attainable at a steeper slope, or the operator perform a field test plot demonstration to demonstrate that a stable and safe condition will be achieved and that the post-mining land use specified in the reclamation plan will not be adversely affected.

NR 135.10(2) (2) Final reclaimed slopes covered by topsoil or topsoil substitute material may not be steeper than a 3:1 horizontal to vertical incline, unless found acceptable through one or more of the following: alternative requirements are approved under s. NR 135.26; steeper slopes are shown to be stable through a field plot demonstration approved as part of an approved reclamation plan; or stable slopes can be demonstrated based on site-specific engineering analysis performed by a registered professional engineer. All areas in the nonmetallic mine site where topsoil or topsoil substitute material is to be reapplied shall be graded or otherwise prepared prior to topsoil or topsoil substitute material redistribution to provide the optimum adherence between the topsoil or topsoil substitute material and the underlying material.

NR 135.10(3) (3) When the approved post-mining land use includes a body of water, the approved final grade at the edge of a body of water shall extend vertically 6 feet below the lowest seasonal water level. A slope no steeper than 3:1 shall be created at a designated location or locations, depending on the size of the water body to allow for a safe exit.

NR 135.11 NR 135.11 Topsoil redistribution for reclamation. Topsoil or topsoil substitute material shall be redistributed in accordance with the approved reclamation plan in a manner which minimizes compaction and prevents erosion. Topsoil or topsoil substitute material shall be uniformly redistributed except where uniform redistribution is undesirable or impractical. Topsoil or topsoil substitute material redistribution may not be performed during or immediately after a precipitation event until the soils have sufficiently dried.

NR 135.12 NR 135.12 Revegetation and site stabilization. Except for permanent roads or similar surfaces identified in the reclamation plan, all surfaces affected by nonmetallic mining shall be reclaimed and stabilized by revegetation or other means. Revegetation and site stabilization shall be in accordance with the approved reclamation plan and shall be performed as soon as practicable after mining activity has permanently ceased in any part of the mine site.

NR 135.12 Note Note: Field test plot demonstrations are highly recommended to ensure that reclamation success standards are met and financial assurance is released as quickly as possible. When field test plots are employed they should be approved as part of the reclamation plan under s. NR 135.19.

NR 135.12 History History: Cr. Register, September, 2000, No. 537, eff. 12-1-00.

NR 135.13 NR 135.13 Assessing completion of successful reclamation.

NR 135.13(1) (1) The criteria for assessing when reclamation is complete and, therefore, when the financial assurance may be released shall be specified in the reclamation plan. Criteria to evaluate reclamation success shall be quantifiable.

NR 135.13(2) (2) Compliance with the revegetation success standards in the approved reclamation plan shall be determined by:

NR 135.13(2)(a) (a) On-site inspections by the regulatory authority or its agent;

NR 135.13(2)(b) (b) Reports presenting results obtained during reclamation evaluations including summarized data on revegetation, photo documentation or other evidence that the criteria approved in the reclamation plan to ascertain success have been met; or

NR 135.13(2)(c) (c) A combination of inspections and reports.

NR 135.13(3) (3) In those cases where the post mining land use specified in the reclamation plan requires a return of the mining site to a pre-mining condition, the operator shall obtain baseline data on the existing plant community for use in the evaluation of reclamation success pursuant to this section.

NR 135.13(4) (4) Revegetation success may be determined by:

NR 135.13(4)(a) (a) Comparison to an appropriate reference area;

NR 135.13(4)(b) (b) Comparison to baseline data acquired at the mining site prior to its being affected by mining; or

NR 135.13(4)(c) (c) Comparison to an approved alternate technical standard.

NR 135.13(5) (5) Revegetation using a variety of plants indigenous to the area is favored.
