21. (6) Nonmajor additions to existing structures may be allowed on bluffs pursuant to a coastal erosion management permit.
22. (7) A coastal erosion management permit is required for new construction, modification or restoration of erosion protection structures, walkways or stairways. Elevated walkways or stairways constructed solely for pedestrian use and built by or for an individual property owner for the limited purpose of providing noncommercial access to the beach are excepted from this permit requirement.
23. (8) Active bird nesting and breeding areas must not be disturbed unless such disturbance is pursuant to a specific wildlife management activity approved in writing by the department.

24. (9) Any grading, excavating, or other soil disturbance conducted on a bluff must not direct surface water runoff over a bluff face.

    (d) Primary dunes.

    The following restrictions and requirements apply to regulated activities on primary dunes:

25. (1) Excavating, grading or mining of primary dunes is prohibited.
26. (2) Vehicular traffic is prohibited on primary dunes, except in those areas designated by the department for dune crossing.
27. (3) Nonmajor additions to existing structures are allowed on primary dunes pursuant to a coastal erosion management permit and subject to permit conditions concerning the location, design and potential impacts of the structure on the primary dune.
28. (4) Foot traffic which causes sufficient damage to primary dunes to diminish the erosion protection afforded by them is prohibited. Pedestrian passage across primary dunes must utilize elevated walkways and stairways, or other specially designed dune-crossing structures approved by the department.
