Yes. According to the amended Pennsylvania Clean Streams Law, a soil and water conservation plan, or, an AG Erosion and Sedimentation Plan is required on every tract of land involving the plowing or tillage of soil, as well as, any disturbance of soil. Today this requirement includes not only cropland, but pastureland and barnyard areas too. The York County Conservation Easement Program requires a Conservation Plan or the Ag E and S Plan for application to the program with at least 50% of the plan implemented. See our Conservation Information Packet for more specifics.
