NMFS issues this temporary rule pursuant to its authority to implement emergency measures under the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act). This emergency rule closes the Nantucket Lightship Access Area (NLS) prior to its scheduled opening on June 15, 2011, and is consistent with Framework Adjustment 22 to the Atlantic Sea Scallop Fishery Management Plan (FMP) (Framework 22), which is currently being proposed and subject to public comments, and which would close the NLS in FY 2011 as well. This closure prevents potentially high levels of scallop and yellowtail flounder (yellowtail) catch that could result from opening the area prior to the approval and implementation of Framework 22, which could be detrimental to the long-term management and health of the scallop fishery.
