B. Work consists of: Construction of a new 5000-gallon propane tank, supplying a new regulator valve, moving the existing propane gas meter, miscellaneous pipe connections and a new concrete pad with six new bollards. Also, this project will construct approximately 220 feet of new 1½-inch HDPE propane gas line from the new propane tank site to the Visitor Center. Approximately 100 feet of gravel approach to the new tank site is included in this project to include minimal grading and tree removal at the new approach and tank site.

The existing 1000-gallon and 500-gallon propane tanks and their concrete pads/bollards shall be demolished and removed along with the existing steel propane gas line. Re-grading the demolished area is required. Purging the existing propane tanks is required and the liquid propane shall be saved and moved to the new propane tank.
