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.
