{"abstract":"The Coast Guard is establishing a Regulated Navigation Area (RNA) for the waters of Lake Michigan within 5 nautical miles from shore from the Chicago Harbor Lock, Chicago, Illinois to Calumet Harbor, Chicago, Illinois. This RNA is intended to allow barges to transit on an alternate route on a portion of Lake Michigan due to the temporary closure of the Thomas J. O'Brien Lock on RM 326.5 on the Calumet River. This RNA is necessary to ensure vessel safety and facilitate commerce.","action":"Temporary final rule.","agencies":[{"raw_name":"DEPARTMENT OF HOMELAND SECURITY","name":"Homeland Security Department","id":227,"url":"https://www.federalregister.gov/agencies/homeland-security-department","json_url":"https://www.federalregister.gov/api/v1/agencies/227","parent_id":null,"slug":"homeland-security-department"},{"raw_name":"Coast Guard","name":"Coast Guard","id":53,"url":"https://www.federalregister.gov/agencies/coast-guard","json_url":"https://www.federalregister.gov/api/v1/agencies/53","parent_id":227,"slug":"coast-guard"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2014/11/17/2014-27168.html","cfr_references":[{"chapter":null,"citation_url":null,"part":165,"title":33}],"citation":"79 FR 68366","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective from November 17, 2014 until March 31, 2015.
