FOTG NOTICE Wl-91

 

Purpose. Revisions to Wisconsin Conservation Practice Standards and Specifications.

Effective Date. This notice is effective upon receipt.

Explanation of Changes.

Section IV: Conservation Practice Standards and Specifications :

Aquaculture Ponds (Code 397) Five year review period. National standard not updated recently. Reviewed with no changes. Date was made current.

Groundwater Testing (Code 355) – Language was added to identify testing parameters for use in microirrigation and livestock consumption.

Saturated Buffer (Code 604) – The national standard was updated to expand the range of applicability of the standard to greater number of field sites, the current 5-percent flow capacity criteria for the saturated buffer is maintained, but designers are now allowed to use an alternate length of the distribution pipe if the 5-percent criteria is found impractical or cost-prohibitive. The required geological investigation for slope stability is also maintained, but designers are allowed an alternate analysis of slope stability based on professional, onsite observations.

Earthfill for Waste Storage Facilities (WCS 204)- The specification was updated to include soil liners. Articulated haul truck was added to the equipment type in Table I, Embankment and Soil Liner Compaction Requirements.
