Trans 401.06(8)(b)1.1. In this paragraph, “karst feature” means an area or surficial geologic feature subject to bedrock dissolution so that it is likely to provide a conduit to groundwater, and may include caves, enlarged fractures, mine features, exposed bedrock surfaces, sinkholes, springs, seeps or swallets. Trans 401.06(8)(b)2.2. No contractor or utility person may knowingly direct site dewatering effluent into surface waters of the state or to a karst feature, unless the sediment in the effluent has been reduced to the maximum extent practicable and the discharge does not create an erosion problem downstream prior to entering a surface water of the state or a karst feature, or unless the department of natural resources has approved the action. Trans 401.06 NoteNote: This paragraph does not require the removal of sediment from dewatering effluent unless the effluent is going to surface waters or a karst feature. The preferred method of disposing of dewatering effluent without removing sediment is to direct the effluent to a pervious area, where water may infiltrate into the ground, instead of directing it into a surface water. Another method to dispose of effluent without removing sediment is to discharge the effluent to a sanitary sewer system. This method may be viable in urban areas where a sanitary sewer system is available, if the sewer authority allows such a discharge.

(8) (b) Register December 2002 No. 564, eff. 1-1-03. Trans 401.07(1g)(a)(a) The department shall prepare the erosion control plan for a project site of a project directed and supervised by the department. Trans 401.07(1g)(b)(b) A utility person shall prepare the erosion control plan for any utility facility project that is not considered a minor utility facility project, unless the department elects to prepare an erosion control plan for the utility facility project. An erosion control plan is not required for a minor utility facility project. Trans 401.07(1j)(a)(a) The erosion control plan shall be developed as part of a project’s design. Temporary best management practices in the erosion control plan shall be based on at least a 2-year 24-hour design storm or a 2-year design storm with a duration equal to the time of concentration. Permanent best management practices in the erosion control plan shall be based on at least a 10-year 24-hour design storm or a 10-year design storm with a duration equal to the time of concentration. Trans 401.07(1j)(b)(b) The erosion control plan shall identify the best management practices to be employed before, during and after the completion of construction or maintenance activity, including the best management practices that will be employed to prevent pollution caused by storm water discharge after completion of the project. The department’s erosion control plan shall require the use of best management practices, alone or in combination as appropriate, that are specified in the standardized erosion control reference matrix published under sub. (1m). The department may require the use of a best management practice not specified in the matrix only if all of the following apply: Trans 401.07(1j)(b)1.1. The department determines through best professional judgment that those other best management practices will control erosion as effectively as the BMPs specified in the matrix published under sub. (1m). Trans 401.07(1j)(b)2.2. The department specifies in writing the reason for selecting that other best management practice. Trans 401.07(1j)(c)(c) The erosion control plan may be prepared in written or pictorial format, or both formats, as necessary and appropriate to convey the design, intent, use and placement of best management practices. Trans 401.07(1j)(d)1.1. For projects directed and supervised by the department, if the department of natural resources, acting through the interdepartmental liaison procedures established under s. 30.2022, Stats., identifies areas or resources that require added safeguards, the erosion control plan shall include those areas or resources and the specific added safeguards as determined in consultation with the department of natural resources. This subdivision applies to any utility facility project that the department determines will be completed in conjunction with or in advance of a transportation facility project that is directed and supervised by the department. Trans 401.07(1j)(d)2.2. For a utility facility project not described in subd. 1., the utility person shall consult with the department of natural resources to identify any areas or resources that require added safeguards. When the department of natural resources identifies areas or resources that require added safeguards, the utility person shall include in the erosion control plan those areas or resources and the specific added safeguards as determined in consultation with the department of natural resources. Trans 401.07 NoteNote: Any activity involving a utility facility that does not require a permit issued by the department of transportation, and any action or area that is associated with a utility facility project but that is not authorized by a permit issued by the department of transportation, is subject to regulation by the department of natural resources.
Trans 401.07(1j)(e)(e) The erosion control plan may be developed as a separate project document or in segmented form throughout the project’s documents, including plans, special provisions, specifications and drawings. Trans 401.07(1j)(f)(f) For a utility facility project that is not considered minor, a utility person shall submit the erosion control plan to the department for its approval along with its request for a permit for the project. The erosion control plan shall include selected sites, if any. The department may not approve the erosion control plan unless the utility person provides some evidence that it has consulted with the department of natural resources as required under par. (d) 2. No person may implement an erosion control plan for a utility facility project, unless the department has approved the erosion control plan in writing. Trans 401.07(1m)(a)(a) The department of transportation, acting jointly with the department of natural resources, shall develop a standardized erosion control reference matrix that identifies best management practices that, when applied as specified in the matrix, meet the performance standards of this chapter, ch. NR 216 and ch. NR 151. The matrix shall address slope erosion and channel erosion and shall identify best management practices that prevent erosion, trap sediment, dissipate flow velocities, and direct the flow of runoff, and that minimize turbidity or silting of surface water caused by site erosion, discharge or runoff. The matrix may consider a variety of site conditions, including drainage area and slope distance. If the secretaries of both agencies, or their designees, recommend, in writing, the use of the matrix, the department of transportation shall publish the matrix in the facilities development manual. Once published, only the joint written statement of the secretaries of both agencies, or their designees, may amend the matrix. Trans 401.07(1m)(b)(b) The department shall review the matrix published under par. (a) at least annually. In performing the review, the department shall consult with the department of natural resources, with an association representing a majority of county highway departments in this state, with a trade association representing transportation facility construction contractors who contract with this state, and with a trade association representing a majority of utility service providers in this state. In performing the review, the department shall consider the best management practices and site conditions described in the matrix, and each best management practice that was required in an erosion control plan during the preceding 12 months that was not specified in the matrix. If upon completing its review the department determines that the matrix should be amended, it shall present its recommendations to the secretary of the department and to the secretary of natural resources.
