Wisconsin Legislature: Chapter NR 152 Appendix A

4. Development of spill prevention and response procedures.

(d) LOCATION. The BMPs used to comply with this section shall be located so that treatment occurs before runoff enters waters of the state.

Note to Users: While regional treatment facilities are appropriate for control of post-construction pollutants, they should not be used for construction site sediment removal.

(4) IMPLEMENTATION. The BMPs used to comply with this section shall be implemented as follows:

(a) Erosion and sediment control practices shall be constructed or installed before land disturbing construction activities begin in accordance with the erosion and sediment control plan developed in S. 08* (2).

(b) Erosion and sediment control practices shall be maintained until final stabilization.

(c) Final stabilization activity shall commence when land disturbing activities cease and final grade has been reached on any portion of the site.

(d) Temporary stabilization activity shall commence when land disturbing activities have temporarily ceased and will not resume for a period exceeding 14 calendar days.

(e) BMPs that are no longer necessary for erosion and sediment control shall be removed by the responsible party.

S. 09* PERMITTING REQUIREMENTS, PROCEDURES, AND FEES.

(1) PERMIT REQUIRED. No responsible party may commence a land disturbing construction activity subject to this ordinance without receiving prior approval of an erosion and sediment control plan for the site and a permit from the [administering authority].
