or unimportant character, or of importance only to the USACE. Omit also lights or fog signals on
ferry slips and on piers used only by certain vessels, and stakes, bushes, and barrel buoys marking
shallow and little-used channels.
c. In placing aids to navigation in connection with harbor or channel improvement works,
USACE district commanders should see that they do not conflict in character or otherwise with
other aids to navigation in the vicinity. USACE district commanders should confer with the
USCG District Commander on this subject.
d. The USCG shall be furnished information, for publication, concerning markers installed
as temporary aids to navigation, for new improvements, in advance of permanent aids, and other
markers that may be established in connection with operations that may serve as important aids to
navigation. Care will be exercised to see that all markers established are not misleading to general
navigation and do not interfere with aids to navigation established by the USCG.
e. The necessary blank forms for reporting information regarding USACE aids will be
furnished upon request by the USCG District Commander.
f. Colors of Dredging Buoys Established by USACE.
(1) In order to distinguish buoys placed and maintained by the USACE for dredging
purposes from aids to navigation placed by the USCG, USACE working buoys will be white with
the top two feet painted light green. The buoys need not be painted to achieve the proper color
markings.
(2) If buoys with special markings are needed to indicate the different sides of the
navigable channel, prior arrangements will be made with the USCG District Commander having
jurisdiction.
(3) Information and regulatory marks are not considered aids to navigation. They shall
conform to USCG standards where practical, however USACE standards in the Sign Standards
Manual shall take precedence.
g. Information to be Furnished by the Corps of Engineers.
(1) District commanders responsible for harbors and waterways shown on charts of the
NOS, will report the channel conditions promptly (as soon as possible), and as ascertained, using
standard tabular forms to:
