Minutes of Previous (February 14, 2002) Meeting No continents by anyone. 2. Recharge.Basin #4 -- Revised Work Plan Bob Terry asked Tom Maher whether or not Terry should begin excavating the concrete debris/existing gas migration control trench located in the area of the cast side drainage system. Tom replied that the concrete should be removed only where necessary, and that he would like Terry to leave some space, if possible, in Recharge Basin #4 for the concrete. Tom mentioned that according to Tiny Howell and Chris Morris, it appears the eastern drainage system and the new gas migration control trench could be installed along the eastern landfill boundary without the need to remove the concrete. Tom added that the filling of Recharge Basin #4 should continue and, if concrete is encountered after the basin is filled, it could possibly be placed in the Borrow Pit. Tom asked Bob how much of Recharge Basin #4 has been filled. Bob answered, approximately 50% to 60%. Tom then asked if Terry had submitted a cost estimate for the geogrid. Bob answered yes. A 13141TO305201(RUl) 1 Z 0021007 IM 3, Status of Aerial Photograph and Surveying_by McLean Tom Maher asked Chris Morris the status of the aerial photograph. Chris replied that Ceomaps,informed him that the photograph would be finished early next week. Tom stated that the Town has decided against the driving range plan for now and that capping of the landfill will proceed as conceptually designed. Tom asked what amount of wood chips has been placed on the east halt' of the landfill. Chris said approximately 2,500 cubic yards have been placed on top of the east side, with an additional 1,500 cubic yards stockpiled around the perimeter. Bob Tent' added that there are roughly 10,000 cubic yards of wood chips remaining on the 17 -acre parcel which still need to be moved. Tom said that the wood chips on top of the east half need to be mixed in well to provide a firm and unyielding surface, and that he is not inclined to place any more wood chips on the east half. Tom asked Bob how he is mixing in the wood chips and what the additional charges will be. Bob replied that an excavator is digging trenches, and the excavated material will be mixed with the wood chips at a charge of $1,500/day. Bob added that there also will be some bulldozer work required at the end of the project at an additional charge. Bob also said he believes the east side of the landfill will be about 1 to 1 %s feet higher, once all of the additional material has been incorporated: Tom thought it would be more. 4. Nonpotable Well Redesion Cost Estimate Tom Maher asked Bob Teriy if he had prepared the cost estimate. Bob said he has not completed the estimate yet, but expects to have it for next week's meeting. 5. West Half of Landfill — Status and Plan for Completion Tom Maher asked if all the liner has been covered with barrier protection layer. Bob 'ferry said almost. Chris Morris said a section on the south end still needs to be covered and that Terry was proceeding in that direction before being asked to transport wood chips Bob said Terry will finish covering the liner on Monday,. Tom asked the 0 13141P0305201(R01) 2 LPJ VU;$/ uu7 03/07/2002 THU 03;48, FAX 0]00.4/007 status of the southwest drainage system. Bob stated the work is completed with the exception of the stilling basin and that they are only waiting for a good day to install it. Tom asked Bob if McLean Associates could survey the locations of the precast structures and provide an as -built, so that D&B could verify the grades before work is completed. Bob answered yes, and that he could provide Tom the as -built within two weeks, Bob informed Tom that Jim Bunchuck had asked him about the possibility of spreading wood chips over the barrier protection layer on the west half,and asked him his opinion on the matter. Tom said he will look into it, but it likely would not be suitable. Jim said once enough of the wood chips have been moved, the Town possibly could rearrange the pile, therefore alleviating the problem. Bob stated that the wood chips currently are being placed in the Borrow Fit and suggested mix ,ig the wood chips with loam. Tom asked if wood chips have been placed in the Borrow Pit previously. Bob answered yes. Tom stated that he prefers transport7ng the wood chips to the borrow pit rather than placing them over the barrier protection layer, and added that the wood chips also could be used to regrade the side slopes of Recharge Basin # 3. Jim said that he will need a cost estimate for the work. Bob said he would provide an estimate to the Town, Tom stated that the estimate should include the 1,500 cubic! yards of wood chips stockpiled around the east side. Tom asked Bob what his plan is for finishing the west side. Bob responded that the plan has not changed, and that the siren and associated electric has been removed and he is waiting for the approval letter from the State to begin well abandonment. Igor Sikiric said the letter has been sent. Bob continued to say that rough grades on the south end need to !be established, and that permanent road construction could begin next week, followed by the removal of the temporary road and underlying waste. Tom stated the material under the teirrorary road needs to be incorporated into the east side as soon as possible in order to complete grading of the east side. 0 1314/TO305101(R01) 3 03/07/2002 THU 08:48; FAX 005/007 j 6. Golf Driving Range Design Tom Maher said he will be drafting a letter to Jim Bunchuck confirming that the landfill closure will be completed as originally conceptually designed, independent of the driving range. Jim stated that the Town's consultant advised them that a driving range could be constructed after the landfill closure is complete using the existing grades. Tom informed Jim that the grades and associated slopes will increase over the current revised grading plan once all of the additional material has been added to the east side. 7. Status of Submittals Tom Maher said he believes all submittals are up to date. 8. Vegetative Cover Mix — Agronomist Certification/ Revised ReDart and Testina by University of Massachusetts Jim lBunuhuck provided c9pies of the University of Massachusetts' completed report to Tom Maher and Bob Terry, which included the particle size analysis of the soil mixture.

Bob added that the land just north of the Cox Lane access road, which is to be used for the eastern drainage system, needs to be cleared. Tom asked what needs to cleared from the area. Bob replied that the area is wooded and that there are trailers and other material belonging to the adjacent property owner which needs to be removed. t Tom said he would like to have McLean stake the property line in the area. Bob suggested that Jim Bunchuck inform the property owner of the situation. Jim said he would do so. 'T'om also suggested talking to Shroder (property owner) about regrading Ids property further north to assist in the slope reduction above Recharge Basin #3. Bob Terry said he does not believe Shroder will be interested in doing so, as he was somewhat reluctant to out down the area to the south. Jim said he would speak with Shroder on the matter. 13. Other Toro Maher asked the status of the measurements of the barrier protection layer on the west side of the landfill. Chris Morris replied that measurements were taken earlier in the week, and the results were discussed with Tom Howell who said that there are no areas on the west side that are finished being graded. 0 13141To30,201(R01) 5 (a006/007 vim, Guu: inu Vo:Jl i Tom Maher asked about the sand stockpile in the borrow pit with regard to the I loam and crushed glass being stripped off and used to fill Recharge Basin n4.
