An Act amending Titles 27 (Environmental Resources) and 53 (Municipalities Generally) of the Pennsylvania Consolidated Statutes, providing for storm water management; and, in municipal authorities, further providing for definitions and for purposes and powers.

This bill establishes a new chapter in Pennsylvania law dedicated to storm water management, aiming to address issues like flooding, erosion, and strain on public infrastructure caused by increased runoff from development. It defines key terms such as "impervious surface" and "storm water" to clarify what areas and water sources are covered under the new regulations. A significant provision allows municipal authorities to charge a reasonable storm water management fee to property owners, including those who own land for the Commonwealth, ensuring that tax-exempt entities also contribute to these costs. The legislation empowers local governments to better plan and mitigate the impacts of storm water while requiring coordination with state instrumentalities.
