An Act amending the act of October 4, 1978 (P.L.864, No.167), known as the Storm Water Management Act, further providing for watershed storm water plans and contents.

This bill requires Pennsylvania counties to develop and update storm water management plans for every watershed within their borders. Counties must create these plans within two years of the environmental department issuing guidelines and review and revise them at least every five years. Municipalities without public water or sewer systems are exempt from participating in the plans. The bill specifies deadlines and regular review intervals for existing county plans under the Storm Water Management Act.
