Section NR 328.32 - Applicability(1) Except as provided in s. 30.2023, Stats., this subchapter applies to construction, placement and maintenance of bank erosion control structures regulated under s. 30.12(1), (1g) (a), and (k), (2m), (3) (a) 3r and 13. and (3m), Stats. Any person that intends to construct, place or maintain a bank erosion control structure in any river or stream shall comply with all applicable provisions of this chapter and any permit issued under this chapter.(2) Erosion control measures such as grading to establish a stable slope, revegetation or other bioengineering methods that do not involve the placement of structures below the ordinary high water mark of a waterway or disturbance of more than 10,000 square feet on the bank are not regulated under s. 30.12 or 30.19, Stats., or this subchapter.(3) Bank erosion control structures solely located above the ordinary high water mark are likely to migrate below the OHWM as the energy of water current is dissipated against the toe of the stream bank. When this migration occurs, the bank erosion control structure is considered subject to the provisions of this chapter.Wis. Admin. Code Department of Natural Resources § NR 328.32
