    obstructions or encroachments, including bridges and culverts owned by railroad companies. Minor deviations
    in the structure’s configuration or filled area including those due to changes in materials, construction
    techniques, current construction codes or safety standards which are necessary to repair, modify or replace
    the water obstruction or encroachment are permitted, provided the environmental impacts resulting from such
    repair, modification or replacement are minimal, those minimal impacts fall within the terms and conditions of
    this General Permit, and there is no adverse impact on public health and safety.

    revoke or suspend the authorization to use this general permit for any project which the Department
    determines to have a significant adverse impact and would not adequately protect public health, safety or the
    environment or otherwise could not be adequately regulated by the provisions of this general permit.
    – Authorization of this General Permit is under Section 7
    of the Dam Safety and Encroachments Act (32 P.S. §§693.1-693.27) and the rules and regulations

    normal pool elevation, the water obstruction is either in the water or adjacent to and abutting the water's edge.
    WATERWAY OPENING – The cross-sectional area of a structure that is available to convey stream flow. This
    area is expressed in terms of span multiplied by underclearance.

    There will be no significant changes to grades of approach roadways or to overtopping
    Increases in culvert length are limited to a maximum of 12 feet perpendicular to the roadway on each
    end of the existing culvert. Appurtenant works beyond the maximum 12 feet increase on each end of
    the culvert, such as, but not limited to, wingwalls, headwalls, bank stabilization, and scour protection
    are also authorized under this general permit. The appurtenant works must be minimized and limited
    to the extent necessary to ensure the protection of the structure, public health and safety, and the
    Increases in bridge width are limited to a maximum of 12 feet on each side of the bridge as
    measured from the upstream side of the bridge deck to the downstream side of the bridge deck.
    Appurtenant works beyond the maximum 12 feet increase on each side of the bridge deck, such as,
    but not limited to, wingwalls, headwalls, bank stabilization and scour protection are also authorized
    under this general permit. The appurtenant works must be minimized and limited to the extent
    necessary to ensure the protection of the structure, public health and safety and the environment.

    The structure may not increase velocity or direct flow in a manner which results in
    accelerated erosion of streambeds and banks.
    Multiple pipes and spans.
    Multi-culvert groups and multiple span bridges which may tend to collect debris, contribute to the
    formation of ice jams, and cause excessive increases in head losses shall be avoided to the
    maximum extent practicable. Spans of less than 15 feet shall be by single-opening structure, except
    where conditions make it impractical to design the crossing with a single span.

    of 12 inches below natural streambed and in such a manner that the average gradient of the invert
    shall not deviate from that of the natural streambed.
    The flow velocities of water discharging from culverts must not cause erosion of the downstream
