(a) The regulations in this subpart shall apply to the structures which are located within the boundaries of the Coast Guard districts hereinafter defined.

(b) Geographic coordinates expressed in terms of latitude or longitude, or both, are not intended for plotting on maps or charts whose referenced horizontal datum is the North American Datum of 1983 (NAD 83), unless such geographic coordinates are expressly labeled NAD 83. Geographic coordinates without the NAD 83 reference may be plotted on maps or charts referenced to NAD 83 only after application of the appropriate corrections that are published on the particular map or chart being used.

(a) Description. See § 3.40-1 of this chapter.

(b) Lines of demarcation. The two lines of demarcation described in this section are for administrative purposes to distinguish between the areas in which structures shall be subject to Class “A”, “B” or “C” requirements. The primary line of demarcation delimits the areas to the seaward of which Class “A” requirements are imposed. The secondary line of demarcation delimits the areas to the shoreward of which Class “C” requirements are imposed. In those areas where no secondary line of demarcation is prescribed, the structures shoreward of the primary line of demarcation are considered to be Class “C” structures. Class “B” requirements are imposed on the structures in the areas between the two lines of demarcation.

(c) Seismographic and surveying operations. (1) All stakes and casings (pipes), except bamboo poles and wooden stakes less than 2 inches in diameter, placed in the water during seismographic or surveying operations shall be marked with flags during the daylight hours. Those casings remaining in place during the hours of darkness shall be marked by a red light as prescribed in Subpart 67.30 of this part.

(2) All buoys used during seismographic operations shall be painted with international orange and white horizontal bands. The buoys shall be of light construction in order that they will not present a hazard to marine commerce.

(d) Spoil marking. (1) All submerged spoil resulting from the dredging of channels, laying of pipelines, or any other operation, which constitutes an obstruction to navigation, shall be properly marked. The spoil banks should be examined at frequent intervals in order that the changing conditions may be kept under control. As markers are no longer required due to settling of banks, the Coast Guard will authorize their removal upon application.

(2) All openings in such submerged spoil shall be marked by daybeacons on each side of the openings. When spoil is located on each side of a channel or pipe line, each bank will be considered separately. The daybeacons shall be equipped with arrows designating the safe water through the opening. These daybeacons may also be used as channel markers for the dredged channels providing they are also equipped with arrows designating the spoil bank openings.

(3) When spoil banks constituting an obstruction to navigation abut an established traveled waterway, the outboard spoil bank markers shall be equipped with quick flashing lights described in Subpart 67.30 of this part, except that the color shall be in accordance with the provisions of Subpart 62.25 of Part 62 of this subchapter.

(e) Applications. All applications for private aids to navigation and all correspondence dealing with private aids to navigation and obstruction lighting must be addressed to Commander (oan), Eighth Coast Guard District, Hale Boggs Federal Building, 501 Magazine Street, New Orleans, Louisiana 70130-3396.

(f) Enclosures. Applicants shall append on a separate sheet with each application, the description, including manufacturer, of obstruction lights and sound signals.

(g) Corps of Engineers correspondence. A copy of all correspondence directed to the District Engineer, Corps of Engineers, U.S. Army, in accordance with condition (i) of the Department of the Army permit, shall be forwarded to the District Commander for those operations conducted under permits authorizing the erection of structures in areas in which Class “A”, Class “B”, or Class “C” requirements must be met.

(b) Line of Demarcation. The line of demarcation described in this section is for administrative purposes to distinguish between the areas in which structures shall be subject to Class “A”, “B”, or “C” requirements. The line delimits the areas to seaward of which class “A” requirements are imposed. The line of demarcation within the jurisdiction of the District Commander is defined as follows:

(1) Commencing at a point of latitude 41°59.8′ N., longitude 124°19.5′ W., thence southward along the seaward limit of the territorial sea to;

(2) A point at latitude 32°32.0′ N, longitude 117°11.0′ W.

(c) Structures located within a half nautical mile of Traffic Separation Scheme Los Angeles/Long Beach will also be subject to class “A” requirements. The traffic separation scheme is depicted on National Ocean Service Charts 18740, 18720, 18725, 18746, 18721.
