On March 30, 1998, the National Oceanic and Atmospheric Administration (NOAA) published a final rule (63 FR 15083) amending the regulations and Designation Document for the Monterey Bay National Marine Sanctuary (MBNMS or Sanctuary) to allow limited, small-scale collection of jade from the Jade Cove area of the Sanctuary. Under the National Marine Sanctuaries Act, the amendment would automatically take effect at the end of 45 days, continuous session of Congress beginning on March 30 1998, unless the Governor of California certified to the Secretary of Commerce the amendment as unacceptable in State waters of the MBNMS. The 45-day review period ended on June 13, 1998. During the review period, NOAA received a letter dated May 29, 1998, from Governor Pete Wilson stating that the State of California has no objection to the amendment. This document confirms the effective date of the amendment of the MBNMS Designation Document and regulations as June 16, 1998.
