Sedimentation control structures definition
Sedimentation control structures means any collection ditch, containment ditch or other conveyance or impoundment used to convey runoff to an impoundment or impound runoff for the purpose of settling out sediment or suspended solids. The impoundment will individually contain less than two acre feet of runoff in addition to sediment storage or contain less than two acres in surface area, whichever is smaller. Non-soil strainer dikes, terraces, riprap and mulches are primarily intended for soil conservation purposes and do not require permits to construct.
