Section 50.86. Sediment basins.

 

(1)   Definition. In this section:

(a) "Sediment basins" means permanent basins that reduce the transport of waterborne pollutants such as eroded soil sediment, debris, and manure sediment. Sediment basins may include containment walls or berms, pickets or screens to filter debris, orifices or weirs to control discharge, and conduits to direct runoff to treatment or discharge areas.

(b) "Maximum storage capacity" means the volume of water, in acre-feet, capable of being stored behind a dam at maximum water elevation without overtopping any part that is not part of the spillway system.

(2)   Eligible costs. A cost-share grant under s. ATCP 50.40 may reimburse the cost of designing and constructing a sediment basin, including costs for heavy use area protection, livestock fencing, filter strips, waste transfer, underground outlets, and critical area plantings.

(3)   Ineligible costs. A cost-share grant under s. ATCP 50.40 may not reimburse the costs for any of the following:

(a) Basins with a structural height of more than 25 feet or with a maximum storage capacity of more than 50 acre-feet.

(b) Basins whose failure may endanger human life, or real or personal property.

(4)   Design, construction, and maintenance. A cost-share grant under s. ATCP 50.40 may not reimburse the cost of installing a sediment basin unless all of the following conditions are met:

(a) Filter strips or buffers are used to filter any discharge from the sediment basin.

(b) The sediment basin complies with all of the following that apply:

1. NRCS technical guide critical area planting standard 342 (January, 2013).

2. NRCS technical guide sediment basin standards 350 (April, 2014).

3. NRCS technical guide waste transfer standard 634 (January, 2014).

4. NRCS technical guide fence standard 382 (January, 2014).

5. NRCS technical guide vegetated treatment area standard 635 (October, 2014).

6. NRCS technical guide heavy use area protection standard 561 (August, 2015).

7. NRCS technical guide underground outlet standard 620 (March, 2014).

8. Wisconsin DNR conservation practice standard 1001, wet detention basin (October, 2007).

(c) The landowner agrees to maintain the sediment basin for 10 years unless farming operations on the affected land are discontinued.
