This interim final rule delays the effective date of an interim final rule amending the Atlantic Large Whale Take Reduction Plan (ALWTRP) from January 22, 2001, until February 21, 2001. Due to the rough January weather conditions in the Gulf of Maine, the affected fishers have not been able to implement the gear modifications in the interim final rule in time to meet the January 22, 2001 effective date. The intent of this delay of effective date is to allow fishers 30 additional days to implement the gear modifications.
