Sec. 132.
"Siltation structure" means a primary sediment control structure designed, constructed, and maintained as required by this article and includes a barrier, dam, or excavated depression that slows water run-off to allow sediment to settle out. A siltation structure cannot include a secondary sedimentation control structure (such as riprap, straw dike, check dam, mulch, dugout, or another measure that reduces overland flow velocity, reduces run-off volume, or traps sediment) to the extent that the secondary sedimentation structure drains to a siltation structure.
