Assess Stormwater Practices on WQ of Runoff Phase
CR1141
The 1987 Amendments to the Clean Water Act required implementation of a two-phase program to regulate discharges of storm water. The regulations were developed in two parts, in three separate programs: (1) Municipal Separate Storm Sewer Systems (MS4s), (2) Construction Activities, and (3) Industrial Activities. Phase I focused on large construction sites, 11 categories of industrial facilities, and major metropolitan MS4s (in Minnesota, this was only St. Paul and Minneapolis). Phase II expands these regulations to include smaller construction sites, industrial activities in small municipalities, and municipalities of larger than 10,000 people. New permits for the Phase II program were filed in March 2003, starting the first five-year implementation cycle.

Various levels of government will spend hundreds of millions of dollars on implementation of storm water treatment practices over the next twenty years. Guidance is needed, and the document “Assessment of Stormwater Best Management Practices” was developed. Visual inspection and testing have been developed as a potentially time- and cost-saving concept that will be advocated when appropriate. They involve making selected investigation of performance, without requiring that input water actually be stormwater runoff. The methodology currently under development includes four levels of assessment, in increasing order of effort:

1) visual inspection,
2) infiltration testing,
3) simulated flood testing, and
4) monitoring.
