d. Chart Corrections.
(1) This section lists all new establishments, deletions, and corrections to federally and privately maintained aids to navigation, as well as chart corrections provided by the National Ocean Service (NOS) and/or the Army Corps of Engineers. Additionally, information received on wrecks and other hazards to navigation as well as reports received from NOS survey vessels shall be listed.
(2) This section is the heart of the Local Notice to Mariners. The information published here is used by mariners to correct their charts, and by the NOS and National
Geospatial-Intelligence Agency (NGA) to initiate chart revisions and Coast Pilot corrections. Accuracy is imperative.
(3) An explanation of the format of the Chart Correction Section shall be listed.
EXAMPLE:
This section contains corrections to federally and privately maintained aids to navigation, as well as NOS chart corrections. This section contains corrective action affecting chart(s). Corrections appear numerically by chart number and pertain to that chart only. It is up to the mariner to decide what chart(s) are to be corrected. The following example explains the individual elements of a typical correction. Chart Chart Edition Last Local Notice Horizontal Source of Current Local Number Edition Date to Mariners Datum Reference Correction Notice to Mariners | | | | | | |

Corrective Object of Corrective Position Action Action
(Temp) indicates the chart correction action is temporary in nature. Courses and bearings are given in degrees clockwise from 000 true. Bearings of light sectors are toward the light from seaward. The nominal range of lights is expressed in nautical miles (M), except in the Ninth Coast Guard District where statute miles are used.
The letter (M) immediately following the chart number indicates the correction should be applied to the metric side of the chart only.
(4) Chart corrections shall be listed in the format described above. Five "Corrective Action Verbs" shall be used. They are: Delete, Relocate, Substitute, Change and Add. These corrective action verbs will cover all situations encountered. (See examples.) (a) The chart number in ascending order, the edition and date of chart, the last Local
Notice to Mariners in the district to affect the chart, the source of the correction, and the Local Notice to Mariners the correction appears in shall be listed. (b) (Temp) shall be listed below the chart number for temporary corrections.
Temporary and permanent corrections shall not be listed together under the same correction.
(c) The official title of the NOAA chart, as well as the Panel/KAPP number shall be listed.
(5) The five corrective action verbs shall be listed in the following order.
(a) Delete shall be used when deleting (discontinuing) an aid or when deleting an object from the chart.

(b) Relocate. Use the verb "Relocate" when something is physically moved. The object being relocated is followed by the former position or "Close", the direction, and the preposition "to." "Close" may be used in lieu of the former position. All changes to the assigned position must be advertised as a chart correction.

(f) Names. The proper name of the aid to navigation (i.e., Jones Point Light 10) shall be listed with each correction.
(g) Frequently Relocated Aids. When a chart note indicates aids are not charted due to frequent relocation, districts should still publish relocation information for the mariner.
(h) The following terms shall always appear within parenthesis: (PA), (Priv maint), (Navy maint).
(i) The color of the light shall always be listed, even if the light is white. Do not use Fl 4s to describe Fl W 4s.
(j) When advertising any chart correction, all information concerning any particular item will be published without regard to the scale of chart. It is up to the mariner to determine how much information is placed on the chart.

(k) Wrecks. A wreck is always written as a permanent notice, even though source material may indicate the wreck is temporary. When wrecks are reported to districts, a correction shall be added along with the name of the wrecked vessel, if known. If an aid to navigation is placed to mark the wreck, the chart correction should indicate whether the aid is permanent or temporary. The wreck will remain on the chart unless a report is received that the wreck has been salvaged. If the wreck is salvaged, then a correction shall be made to delete the wreck. If a wreck is searched for and not found, a correction shall be issued to add the designation (PA) to the previously reported wreck. The legends "ED" (existence doubtful) or "PD" (position doubtful) shall not be used. Never use the expression "non-dangerous wreck". Use either "wreck," "visible wreck," or "dangerous wreck."

(l) Shoals, Rocks, and Piles. Information on shoals, rocks, and piles shall be reported as received. If a report is received in March 2004 that there is shoaling in a particular area, the district shall publish the correction as "Shoaling Rep Mar 2004", and give the geographic position of the shoal. Rocks and piles should be handled in the same manner. If an aid to navigation is placed to mark the hazard, the chart correction should indicate whether the aid is permanent or temporary. EXAMPLES:
