The Coast Guard announced the publication of a notice of proposed rulemaking to revise the regulations governing waterfront facilities that handle liquefied natural gas and liquefied hazardous gas, 33 Code of Federal Regulations part 127. The proposed modifications would affect the process for the submittal of Letters of Intent by owners/operators, as well as issuance of Letters of Recommendation by the Coast Guard Captains of the Port. Under the proposed rule, when an owner/operator proposing to build or modify a liquefied natural gas/liquefied hazardous gas facility submits a Letter of Intent to the Captain of the Port, the owner/operator would be required to conduct a Waterway Suitability Assessment for liquefied natural gas/liquefied hazardous gas marine traffic.
