Short Description

Controlling soil-laden stormwater runoff at construction sites can be a challenge. Flocculants, substances that cause suspended particles to clump into larger particles, can reduce turbidity in construction site runoff. However, if not used according to label directions these substances can be toxic to aquatic species and has the potential to cause fish kills. This story highlights how one company worked with the Chemical Technology Assessment Protocol – Ecology (CTAPE) review process to ensure that its flocculant, a chitosan product, is safe when used as directed and also receive a Conditional use level designation (CULD). The company worked with the Chemical Technical Review Committee (CTRC) to develop procedures, determine proper dosing rates, and to develop a field test for water treated with the chemical.
