Custodian: WDNR

Goal: The Standard Team created a new technical standard that can be used to determine the efficacy of proprietary storm water filtration devices. This team defined the criteria and procedures to determine the reduction in total suspended solids and total phosphorus using proprietary filtration devices. Development of this standard included the review of existing research and procedures utilized by other state programs along with input from government and industry experts.

Initial Review: November 2019

Broad Review: March 17, 2020 to April 17, 2020

Publication Date:  September 2020 – The following documents were created by the SOC team as part of WDNR Technical Standard 1010: the Technical Standard, the Technical Note, and the Filter Efficiency Adjustment Spreadsheet.

The final published files are available on the WDNR website.

Work Team Status: This team began meeting in August 2018. Meetings were held approximately monthly until the draft standard was completed.  Meetings agendas and notes are available in the left sidebar.
