Removing Sediment Behind Tidegates - Mandatory Requirements

The Department will review each notification to ensure that a project complies with the following mandatory requirements:

(1)

The removal of sediments from drainage ditches must be kept to the minimum amount necessary to remove recently deposited materials. Additional channel widening or deepening beyond that amount is not allowed under this General Authorization.

(2)

The sediments removed from drainage ditches may be spread in a thin layer (three inches or less) on farmed wetland or wet pasture provided the effects are temporary and there is no permanent conversion from wetland to upland. Freshwater wetland (other than farmed wetland or wet pasture mentioned above), salt marsh, tidal flats or permanent or semi-permanent open water areas must not be used for sediment disposal.
