Public information and participation is one the keys to preventing stormwater pollution.  The general public needs to understand what causes stormwater pollution and the simple things that can be done to prevent pollution from entering the storm drain system.  City drain inlets have medallion markers as a reminder.  

The EPA website has information on What You Can Do to Prevent Nonpoint Source Pollution.

Developers, builders and project applicants should review the "Current Stormwater Quality Control Requirements" (updated July 2016).
