An Act amending the act of November 26, 1978 (P.L.1375, No.325), known as the Dam Safety and Encroachments Act, further providing for definitions and for projects affecting submerged lands of the Commonwealth.

SB 109 amends Pennsylvania's Dam Safety and Encroachments Act to define "groin structure" as a shore structure affecting erosion, waves, or flooding. It adds a $250 license fee for individuals or entities constructing, repairing, operating, maintaining, or removing such structures on Commonwealth submerged lands. The bill directly affects property owners, developers, and coastal managers working with shoreline infrastructure. Key provisions are Section 3 (new definition) and Section 15(f) (fee), effective 60 days after enactment. The bill was approved by the Governor on June 30, 2025, as Act No. 19 of 2025.
