Program Information
The National Municipal Stormwater and Green Infrastructure Awards program, led by the Water Environment Federation (WEF), was established in 2015 through a cooperative agreement with the U.S. Environmental Protection Agency (EPA) to recognize high-performing regulated Municipal Separate Stormwater Sewer Programs (MS4s).
The objective of this program is to inspire MS4 Phase I and Phase II program leaders to seek innovative ways to meet and exceed regulatory requirements in a manner that is both technically effective as well as financially efficient. Submissions undergo a selection process wherein their submission is reviewed by an expert committee and evaluated in two categories: program management and innovation.
Based on the committees scoring, applicants are designated as Bronze, Silver, or Gold community programs. The high-performing programs(s) of each MS4 Phase within in each category will be selected as the category winner. Additionally, the Phase I and Phase II programs with the overall highest score will be honored as the formal winners of the year’s National Municipal Stormwater and Green Infrastructure Awards Program. The Phase I and Phase II winners of each category (i.e. program management, innovation, and overall winner) are traditionally recognized during WEFTEC.
