The US Coast Guard is conducting a Pacific Coast Port Access Route Study (PAC-PARS). The PAC-PARS will consider whether existing or additional routing measures are necessary to improve navigation safety due to factors such as planned or potential offshore development, current port capabilities and planned improvements, increased vessel traffic, existing and potential anchorage areas, changing vessel traffic patterns, effects of weather, or navigational difficulty. Mariners are encouraged to participate in this study by submitting comments and input to the Federal Register. To submit your comment online, go to https://www.regulations.gov, and insert Federal Register docket number “USCG-2021-0345” in the “search box”. Click “Search” and then click “Comment Now”. Comments and material must be received on or before Jan. 25, 2022.
