Notes<br />
1. Struckout items are either completed or not used in the geosynthetics <strong>final</strong> cover design<br />
2. Cover Profile - foundation layer (1 ft already in place), HDPE geomembrane , and Artificial Turf layer.<br />
3. Structured geomembrane/Artificial Turf on top deck and side-slopes. Unit costs reflect<br />
2009 construction season bids for geomembrane and geocomposite materials (inc. purchase, sales tax, and installation).<br />
4. LFG control system installation consists of collection piping network and geocomposite panels along topdeck perimeter and<br />
sideslopes (beneath liner)<br />
5. Groundwater monitoring system in-place. The existing network is sufficient to monitor site through<br />
post-<strong>closure</strong> per WDR R3-2007-0003 specifications<br />
6. New fence installation along southern boundary to increase security of groundwater wells has been completed.<br />
