During Tuesday's public business meeting, the U.S. Chemical Safety Board ("CSB" or "agency") voted to close two recommendations issued to the Bureau of Safety and Environmental Enforcement ("BSEE"), the agency within the Department of the Interior that regulates offshore oil and gas drilling on the U.S. Outer Continental Shelf ("OCS"), in connection with the Macondo incident investigation. During the agency's October public business meeting, Chairperson Vanessa Sutherland explained that the CSB had engaged in "extensive communication" with BSEE about the recommendations, and BSEE ultimately made clear that it disagreed with one of the recommendations and believed it did not have the statutory authority under the Outer Continental Shelf Lands Act ("OCSLA") to implement the other.
