WETLANDS PROTECTION ACT HEARING CONTINUATION - SE211 -331 - Landfill capping Gary Heathcoff and Greg Roy of CDM were present, along with the Town Engineer and his assistant. In answer to a question from Chairman Ouellette, the the Town Engineer commented that his reservations and concerns about the filing have been addressed, and the drainage calculations have been completed. Pre -and post- construction flows have been balanced. Comm. Cauldwell: Which way does the groundwater flow? Mr. Swanson answered that the second part of the study is a hydrogeologic survey (this part of the project has not begun). It will involve additional monitoring wells and will address other questions regarding groundwater. Comm. Cauldwell commented that the more water dumped at northern side, the more pressure there will be on on the water that is there, possibly forcing groundwater closer to wetlands. His concerns were based on the fact that the site is filled swamp /wetlands. The capping procedure does not address this problem.\ The capping procedure, however, has been discussed with DEP, and the closing is proceeding according to their recommendations and regulations. There will be no wet basin as previously proposed, check dams only. All waste will be pulled back under the cap. Chairman Powers: How will drainage swale crossing the perimeter "road" be handled? Her concern is that if the swale is crossed by vehicles, there might be erosion into wetlands. Entire swale will be riprapped. The perimeter is not designed specifically for access, but makes access possible. After two to three cuttings (following hydro- seeding), Mssrs. Heathcoff and Roy feel the cap is complete, okay for foot traffic, etc. If closing is not completed this growing season, the commission would want to see a stabilization plan. Carol Dunn, 395 East St., abutter - what kind of buffer zone will there be during the working period? She was shown extent of cap, perimeter "road ", etc. Siltation control devices will be installed. Intent is to minimize any cutting. MOTION: To close the hearing.
