The US Coast Guard is soliciting public comment on proposed changes to the computer application for electronic Notice of Arrival (NOA) on the US outer continental shelf (OCS).  The Coast Guard is particularly interested in comments on: (a) the addition of one data field to consist of a free-form block that will allow additional voluntary information (e.g., route, day planning) to be submitted; (b) the ability to submit up to five consecutive ports or places on the OCS; and (c) ways to enhance the quality, utility, and clarity of information submitted through the electronic application.  Comments should be submitted by 19 November77 Fed. Reg. 57572  (September 18, 2012).
