Water running over hard surfaces can pick up sediment, chemicals, debris, and toxins which are carried to local waterways. These pollutants prevent waterways from being fishable and swimmable. In 2012, the State of Maryland passed the Watershed Protection and Restoration Program (HB- 987) which mandates that counties subject to a certain municipal stormwater permit institute a stormwater remediation fee. The purpose of the fee is to manage pollution carried by stormwater into local waterways.
