[Docket No. USCG-2016-1061]


Termination of U.S. Coast Guard Rebroadcast of HYDROLANT and 
HYDROPAC Information

ACTION: Notice of rebroadcast termination.

-----------------------------------------------------------------------

SUMMARY: The United States Coast Guard is ceasing the rebroadcast of 
HYDROLANT and HYDROPAC (defined below) navigational warnings over HF 
SITOR (defined below). There is no requirement for the Coast Guard to 
rebroadcast this information, although the Coast Guard has been 
voluntarily doing so for a number of years, and doing so is duplicative 
of the National Geospatial-Intelligence Agency's broadcast. The 
information will continue to be disseminated by the National 
Geospatial-Intelligence Agency.

DATES: The Coast Guard will cease rebroadcasting HYDROLANT and HYDROPAC 
navigational warnings on August 30th, 2018.

FOR FURTHER INFORMATION CONTACT: For information about this document, 
please call or email Derrick Croinex, Chief, Spectrum Management and 
Telecommunications Policy, U.S. Coast Guard (Commandant CG-672); 
telephone: 202-475-3551; email: <a href="/cdn-cgi/l/email-protection#cfabaabdbda6aca4e1a5e1acbda0a6a1aab78fbabcaca8e1a2a6a3"><span class="__cf_email__" data-cfemail="56323324243f353d783c783524393f38332e1623253531783b3f3a">[email protected]</span></a>.

SUPPLEMENTARY INFORMATION: On May 14, 2018, we published a notice in 
the Federal Register at 83 FR 22276 that the Coast Guard was 
considering no longer rebroadcasting HYDROLANT and HYDROPAC 
navigational warnings over HF SITOR (High Frequency Simplex Teletype 
Over Radio service). HYDROLANT warnings are Navigational Warnings 
Categorized by their Atlantic Ocean Location. HYDROPAC warnings are 
Navigational Warnings Categorized by their Pacific Ocean/Pacific Rim 
Location. Both are products of the National Geospatial-Intelligence 
Agency. The May notice included relevant background information on 
these navigational warnings and reasons for terminating rebroadcast. 
After a full consideration of the matter, including public comment, we 
have decided to stop rebroadcast. The Coast Guard will cease 
rebroadcasting HYDROLANT and HYDROPAC navigational warnings in 30 days.
    In the notice, we requested feedback from the public on the 
proposed termination. The comment period closed on July 13, 2018. We 
received one submission in response to our inquiry. The commenter was 
concerned that the information contained in the Coast Guard rebroadcast 
would no longer be available. In response to the comment, we would like 
to reiterate that the HYDROLANT and HYDROPAC products will still be 
available via satellite from the National Geospatial-Intelligence 
Agency as originally intended. The Coast Guard is only terminating the 
rebroadcast of these products, and only these products, via HF. All 
other HF Broadcast content will continue to be available.
    This notice is issued under authority of 14 U.S.C. 93(a)(16) and in 
accordance with 5 U.S.C. 552(a).

    Dated: July 30, 2018.
Derrick J. Croinex,
Chief, Spectrum Management and Telecommunications Policy.
