In the Water Quality Act of 1987 (1987 WQA) Congress responded to the stormwater problem by requiring that industrial stormwater dischargers and municipal separate storm sewer systems (often called “MS4″) obtain NPDES permits, by specific deadlines. The permit exemption for agricultural discharges continued, but Congress created a nonpoint source pollution demonstration grant program at EPA to expand the research and development of nonpoint controls and management practices.

Lori Belz spends a great deal of her work time along the highways and other roads of Minnesota, trying to gauge the best approach to erosion control. One of the more interesting research projects in which she has been involved was in bioengineering, trying to stabilize slopes along Minnesota highways

Salt: No Easy Answers

Salt: No Easy Answers

The issue of groundwater and surface water contamination resulting from road deicing salt use is one of contaminant mitigation, not best management practices (BMPs). Nothing can be done to remove salt and its compounds once they get into water supplies, so the management focus is on reducing or eliminating salt

BMP Design and Selection

BMP Design and Selection

Post-construction stormwater BMPs are not one size fits all. And as the project lead – between calculating the stormwater runoff rates and volumes, calculating the flow velocity and conveyance / impoundment depths, and modeling these in your specific environment – selecting and designing the proper stormwater BMP for your site

Continuing Education: Two Free Webinars

Two free webinars coming up at Forester University will be of interest to stormwater professionals. These sponsored webinars each earn participants 1 PDH or 0.1 CEU. You can see a complete list of upcoming webinars here, and a list of on-demand webcasts here.

Simplifying Stormwater Detention Design With Precast Concrete & Hydrologic Modeling

Simplifying Stormwater Detention Design With Precast Concrete & Hydrologic Modeling

Increasingly, stormwater management for buildings and facilities is going underground. Offering smaller footprints, larger stormwater capture, and better flow mitigation, many water utilities and facilities are looking to incorporate underground precast stormwater detention/retention systems at their sites to meet NPDES MS4 permit and Low Impact Development (LID) requirements. But…how do you
