Section 141-085-0525 - Measuring and Calculating Volume of Removal and Fill

(1) Calculating Removal Volume. Removal volume for all waters includes the full extent of the excavation or movement within the jurisdictional areas.

(2) Calculating Fill Volume. For waters other than wetlands, fill volume is measured to the ordinary high water line (OHWL) or the highest measured tide (HMT). For wetlands, fill volume is measured to the height of the fill, excluding buildings.

(3) Calculating Volume for Channel Relocation. When calculating the volume for channel relocation, the threshold is met considering either:

(a) The volume of material removed to construct the new channel up to OHWL; or

(b) The volume that would be required to completely fill the old channel to the OHWL or HMT.

(4) Projects that Involve Both Fill and Removal. For projects that involve both fill and removal, the combined volumes are used to determine whether a permit is required.
