"We want to express our concern that if offshore wind and other renewable energy remain under the jurisdiction of BOEMRE during the reorganization, the development of an offshore energy plan for our country may be compromised," the congressmen wrote.
BOEMRE was created from a re-organisation of the Minerals Management Service (MMS) after the explosion of the oil rig Deepwater Horizon.
Developers have expressed concern that the re-organisation could slow permitting for offshore wind farms.
The congressmen added: "While BOEMRE is focused on the critical task of transforming itself into a more effective, transparent regulator, the progress the Department has made in promoting offshore wind must continue."
The signers were Democratic senators Thomas Carper and Edward Kaufman, both of Delaware, Republic senators Susan Collins and Olympia Snowe, both of Maine, Democratic representatives Paul Tonko of New York and Kathleen Dahlkemper of Pennsylvania, and Republican representatives Michael Castle of Delaware, Roscoe Bartlett of Maryland and Frank LoBiondo of New Jersey.
