No changes shall be made in the contour of the land, no grading, excavating, removal or destruction of the topsoil, trees or other vegetative cover of the land, or other earth disturbance activity as defined in Title 25 of the Pa. Code, § 102.1, shall be commenced until a determination has been made by the York County Conservation District whether, or to what degree, or not an erosion and sedimentation control plan (E&S plan) is required. To the extent that a formal E&S plan is not required by the York County Conservation District, then proposed erosion and sedimentation control measures shall be noted on the subdivision or land development plan. Additionally, every such plan shall be presented to the York County Conservation District, which shall either review and approve such plan, or issue a waiver letter to the Borough advising that no review by the York County Conservation District is required because of the size and location of the excavation. Waivers will only be permitted by the Borough for any activities identified in Subsection A which involves less than 5,000 square feet. In all other events, a review and approval of such plan by York County Conservation District shall be required.
