Howell Terry Contracting &'Materials 1. Comments on Minutes of October 4, 2000. Progress Meeting Mein 10 of these minutes, Interface Friction Tests, is wrongly worded as stated by Bob Terry. The item should read, "Bob Terry said he is still waiting to receive laboratory test results;. He aloo stated that the liner installer indicated it would be OX to install 6 -inch to 12-hacb modified rip rap on the composite over the liner," ltern 16 of these minutes, Removal/lvlovement of Temporary Access load to 17 -Acre Parcel and Access from Depot Lane, is incorrect as recalled by Bob Terry and Tim Howell. Specifically, ti-JeL statement, "If nemssary during construction of the permanent road and cap, the temporary road would be relocated at no cost to the Town;" was never made. Any relocation of the temporary road necessary may incur a cost to the Town. Also, this item states, "Bob Teary said that the permanent road will first be installed and, only thereafter, would the temporary road be removed." Bob Terry stated that he will make a good faith effort to do so, but such action is dependent on the design of the proposed permanent access road. 2.

Tom asked Bob Terry at what angle the trench would be dug based on the Lest trench dug a few days ago. Bob responded that it was about 45 degrees. Tom said be would prefer a 7 on 1 slope since space may be a problem, especially on the south end near the property line and permanent road. Bob said he would study this further and agreed space may be an issue. Torn also said that a 4-foot.PVC riser, rather than the 3 -foot proposed in Terry's drzii&ing, should be installed for the trench vents. Bob agreed with this change.

Bob Terry said he will talk to his surveyor, McLean Associates, about the stakes for the cap limit on the south end where they appear to have been located in error.
