The 2018 State of Stormwater Report report provides a brief overview of stormwater programs in participating states. The information was compiled by National Municipal Stormwater Alliance member organizations and does not reflect any official state position on permit compliance or receiving water quality. Rather, the information provided is a snapshot of overall MS4 NPDES program implementation, current regulatory issues in the state, and a general estimate of the trend and overall quality of the state’s receiving waters.
