ADDITIONAL CONSULTANT SUPPORT Mr. Sterk reported on his recent contact with Mr. Robin Lewis, the consultant who worked on originally establishing the Clam Bay hand-dug channels. Mr. Sterk commented that Mr. Lewis is available and interested in Clam Bay consulting work, for which a detailed scope of work would need to be developed. Mr. Ventress commented that any discussion with Mr. Lewis is premature at this time. PREVIOUS PERMITS FOR WORK IN CLAM BAY Ms. O'Brien provided copies of previous permits for work in Clam Bay, including (1) the original permit which allowed for work to increase the depth and width of existing channels, and (2) a permit which was issued to pump water out of Clam Bay; however, the permit was never actually used. INTERVENTION STRATEGIES Ms. O'Brien suggested that further discussion on intervention strategies be postponed until after the elevation survey is evaluated.
