    (a) Description. See Sec. 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.

    (1) The coordinates of the primary line of demarcation within the 

jurisdiction of the District Commander are as follows:

    (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.
