• • Road Reclarr~ation Costs Assumptions 1. Only those roads that are "outside" the footprint of another facility as shown the Reclamation Map (only one road -East Cresson to Main Cresson Haul Rd) 2. Roads that serve as access to the pits will not be shown in this exercise, because they will be reclaimed as part of the backfilling effort. 3. Road reclamation consists of grading the disturbed area, growth medium replacement to a depth of 6 inches, simultaneous fertilizing and ripping, and revegetation. 4. Revegetation will consist of handseeding and hydroseeding. The steeper slopes will be hydromulched. 5. It has been assumed that all of the areas under "road reclamation" will be subject to the tree planting effort.
