SUPPLEMENTARY INFORMATION:

The Coast Guard will enforce a segment of the Safety Zone; Brandon Road Lock and Dam to Lake Michigan including Des Plaines River, Chicago Sanitary and Ship Canal, Chicago River, Calumet-Saganashkee Channel, Chicago, IL, listed in 33 CFR 165.930. Specifically, the Coast Guard will enforce this safety zone on all waters of the Chicago Sanitary and Ship Canal between Mile Marker 296.1 to Mile Marker 296.7. Enforcement will occur intermittently from 8 a.m. to 6 p.m. on Monday through Friday, from August 3, 2015, through August 14, 2015. In the event of a postponement of the trial tests due to inclement weather or other unforeseen circumstances, this zone will be enforced intermittently from 8 a.m. to 6 p.m. on August 17, 2015, through September 18, 2015, excluding September 7, 2015.

This enforcement action is necessary because the Captain of the Port Lake Michigan has determined that the U.S. Fish and Wildlife Service's trial tests on the water for Asian Carp studies pose risks to life and property. Because of these risks, it is necessary to control vessel movement during the operations to prevent injury and property loss.

In accordance with the general regulations in § 165.23 of this part, entry into, transiting, mooring, laying up, or anchoring within the enforced area of this safety zone by any person or vessel is prohibited unless authorized by the Captain of the Port Lake Michigan or her designated representative.

Vessels that wish to transit through the safety zone may request permission from the Captain of the Port Lake Michigan. Requests must be made in advance and approved by the Captain of the Port before transits will be authorized. Approvals will be granted on a case by case basis. The Captain of the Port representative may be contacted via U.S. Coast Guard Sector Lake Michigan on VHF channel 16.

This document is issued under authority of 33 CFR 165.930 and 5 U.S.C. 552(a). In addition to this publication in the Federal Register , the Captain of the Port Lake Michigan will also provide notice through other means, which may include Broadcast Notice to Mariners, Local Notice to Mariners, local news media, distribution in leaflet form, and on-scene oral notice. Additionally, the Captain of the Port Lake Michigan may notify representatives from the maritime industry through telephonic and email notifications.
