(e) Physical characteristics of the obstruction;

(f) Possible movement of the obstruction;

(g) Location of the obstruction in relation to other obstructions or aids to navigation;

§64.33   Marking by the Coast Guard.

(a) The District Commander may mark for the protection of maritime navigation any structure, sunken vessel or other obstruction that is not suitably marked by the owner. Markings established by the Coast Guard do not relieve the owner's duty or responsibility to mark the sunken vessel or other obstruction, or to remove it as required by law.

(b) Costs for markings established by the Coast Guard will be determined in accordance with part 74 of this Chapter.

(c) Costs for marking of a sunken vessel or other obstruction shall be charged to the owner and shall continue until:

(1) The vessel or other obstruction is removed;

(2) The right of the owner to abandon is legally established and has been exercised; or

(3) The District Commander directs otherwise.

Note: When the needs of navigation permit, the owner may be given reasonable opportunity to establish and maintain the necessary markings.
