Please join Wisconsin Land+Water for a webinar to review the new DNR Technical Standard 1010 for Proprietary Storm Water Filtration Devices. These are commercially available flow-through devices to remove storm water pollutants. They are generally below ground chambers with replaceable granular media cartridges or membrane. The potential use and general sizing of these devices to meet ch. NR 151, Wis. Adm. Code, post-construction performance standards for total suspended solids and total phosphorus will be discussed.
