Requires the department of ecology to update the guidelines required under this act, as necessary, after the completion of the geoduck research by the sea grant program at the University of Washington.

Establishes the shellfish aquaculture regulatory committee to, consistent with this act, serve as an advisory body to the department of ecology on regulatory processes and approvals for all current and new shellfish aquaculture activities, and the activities conducted pursuant to RCW 90.58.060, as the activities relate to shellfish.
