Design work began in late 2007 and was coordinated with the ongoing permitting effort"for an amendment for vertical :expansion at the - landfill, The project was bid in' late 2008 and constructiori began.in January of 2009. The project is, complete with the exception of finatproeessing.of closeout paperwork and change orders regarding the purchase of the vegetation irrigatign system. Additional services. were'provided on this project. during the design phase.

A more detailed description of the services provided is provided in the following paragraphs. Desig Phase Passive vs. Active LFG management system. Our original contract called for the design of the LFG management system to be a passive venting system. This system would have installed , passive vents on'a spacing of about one per acre throughout the landfill to relieve.LFG pressures and prevent damage to the .final cover system and prevent offsite LFG migration.

The design of the entire system also involved connecting it to the existing LFG collection system installed, in 1.997 as well as connecting all of -.,the individual wells installed by a third party developer,-RTC (also in the-late 1990's). This change in scope resulted in. seven. additional plan sheets be added to the construction documents as: well as eight additional technical specification. sections. - -- ` Perimeter Fence Replacement.

New Groundwater Monitoring Wells.
