Sec. 995.23  Acquisition of data.



    (a) CED or CEVAD shall obtain official NOAA ENC[supreg] files only 

by directly downloading them from an official NOAA ENC site on the 

Internet.

    (b)(1) After downloading NOAA ENC files, CED or CEVAD shall 

uncompress the files and compute a CRC checksum value for each NOAA ENC 

file and verify that it matches the CRC checksum value contained in the 

CATALOG.031 file provided with the NOAA ENC files by NOAA. This is to 

ensure that no NOAA ENC files have been corrupted during the download 

process.

    (2) In the event that said CRC checksum value does not match that in 

the CATALOG.031 file, CED or CEVAD agrees to:

    (i) Repeat the download process;

    (ii) In the event that said CRC checksum value for the repeat 

download does not match that in the CATALOG.031 file, immediately notify 

the NOAA ENC Production Manager at enc.chartproduction@noaa.gov, and;

    (iii) Not redistribute any NOAA ENC that does not have a valid CRC 

checksum.
