(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.
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.
