SedimentBasin_ClarkCountyThe NRCS Standard 632, Solid/Liquid Waste Separation Facility, and Standard 350, Sediment Basin, have been revised and are available for comment from Tuesday, March 4th to Tuesday March 25th.

The Standard 632 (name revised to Waste Separation Facility) has been reorganized and updated with additional content.  The new national standard format has been used.  The barnyard sediment basin criteria from Standard 350, Sediment Basin, has been moved to Standard 632. Standard 350 will no longer deal with wastes.

In both draft standards below, the main revisions from the national standard are highlighted in yellow.  The green shading in Standard 632 is the material inserted from WI Standard 350 for livestock sediment basins.
