WDNR has worked with internal staff to revise two interim Technical Standards, 1050 and 1051, and is now soliciting public comments on the proposed revisions.   The intent of the revisions are to reflect the April 2015 “Water Quality Review Procedures for Additives” guidance. The guidance provides comprehensive procedures for the review of additives for potential toxicity. Additionally, the standards have been broadened to use the term “additive” to be all inclusive with the use of polyacrylamide and other polymers.

The following draft standards will be available for comment from October 5th to October 26th.

Technical Standard 1050, Land Application of Additives for Erosion Control – originally titled “Erosion Control Application of Anionic Polyacrylamide”

Technical Standard 1051, Water Application of Additives for Sediment Control – originally titled “Interim Sediment Control Water Application of Polymers”

After the 21 day comment period is complete, all comments will be reviewed and the technical standard will be updated. The final technical standard will then be posted and available on the WDNR website.
