January 19 webinar: Pretreatment - how can we do better?

Title. Pretreatment: how can we do better?

When. January 19, 1:00-2:30 PM Central Standard Time

Speakers

• Dr. John Chapman, University of Minnesota - discussion of pretreatment and solids
• Mike Isensee, Adminstrator of Carnelian Marine St. Croix Watershed District, and Noah Czech, Stormwater Compliance Specialist, City of St. Cloud, MN - pretreatment practices and approaches in the field
• Chris French, National Regulatory Manager for BioClean - Observations (the good, bad, and ugly)

Abstract: The Minnesota Construction Stormwater Permit requires pretreatment for filtration and infiltration practices. Forebays or other pretreatment practices are highly recommended for constructed stormwater ponds. The permit, however, does not specify the type of or sizing for pretreatment practices. We are discovering that many stormwater best management practices (bmps, also often called stormwater control measures or scms) are not performing as designed, often due to heavy sediment loads to the bmp and to poor design.

In this webinar, speakers will discuss solids in stormwater runoff and the role of pretreatment, some preferred approaches to implementing pretreatment practices, and some observations of pretreatment implementation. We’ll also briefly go through pretreatment information in the Minnesota Stormwater Manual.
