The purpose of the webinar is to provide an overview of the updated guidance and technical standards associated with additive use in construction, industry, and agriculture. Webinar Content
-Definition of Additive Description of Land-applied and Water-applied Additives
-Assessing the aquatic toxicity of additives
-Determination of the secondary acute value
-Determination of the allowable usage rate
-Question and answer opportunities
The Department of Natural Resources has recently updated guidance and technical standards associated with the use of land and water-applied additives.
The Water Quality Review Procedures for Additives guidance describes the process the Department uses for assessing the toxicity of additives. Technical Standard 1050 - Land Applied Additives for Erosion Control and Technical Standard 1051 - Water Applied Additives for Sediment Control establish an updated process for customers to obtain an additive allowable usage rate where runoff of additives to waters of the state may occur.
The webinar speakers are: Jan C. Kucher, P.E., Water Resources Engineer at the Wisconsin DNR. Jan joined the WDNR after over 30 years of consulting engineering design and construction experience. He is responsible for the preparation of technical standards and guidance associated with surface water runoff. Jan also reviews customer additive toxicity submittals and performs calculations to arrive at the allowable usage rate for additive products. Sarah Yang, PhD, Environmental Toxicologist at the Wisconsin DNR. Sarah joined the WDNR after earning her PhD in molecular and environmental toxicology at the University of Wisconsin-Madison. She is involved in the development and revision of water quality criteria for the protection of Wisconsin's surface waters. Sarah also addresses questions related to the secondary value calculations and the toxicity of additives.
