Section 648.70 - Surfclam and ocean quahog Annual Catch Limit (ACL)(a) The MAFMC staff shall recommend to the MAFMC ACLs for the surfclam and ocean quahog fisheries, which shall be equal to the ABCs recommended by the SSC. (1)Sectors. The surfclam and ocean quahog ACLs will be established consistent with the guidelines contained in the Atlantic Surfclam and Ocean Quahog FMP. The ACL for ocean quahog will then be allocated to the Maine and non-Maine components of the fishery according to the allocation guidelines of the Atlantic Surfclam and Ocean Quahog FMP as specified in § 648.78(b) .(2)Periodicity. The surfclam and ocean quahog ACLs may be established on an annual basis for up to 3 years at a time, dependent on whether the SSC provides single or multiple year ABC recommendations.(b)Performance review. The MAFMC staff shall conduct a detailed review of the fishery performance relative to the ACLs at least every 5 years.(1) If the surfclam or the ocean quahog ACL is exceeded with a frequency greater than 25 percent (i.e., more than once in 4 years or any 2 consecutive years), the MAFMC staff will review fishery performance information and make recommendations to the MAFMC for changes in measures intended to ensure the ACL is not exceeded as frequently.(2) The MAFMC may specify more frequent or more specific ACL performance review criteria as part of a stock rebuilding plan following a determination that a stock has become overfished.(3) Performance reviews shall not substitute for annual reviews that occur to ascertain if prior year ACLs have been exceeded, but may be conducted in conjunction with such reviews. 76 FR 60622 , Sept. 29, 2011
