Mineral material for this project will be free-use as long as it is utilized within the ROW. A Special Use Permit has been obtained from the Arapaho National Forest to authorize activities within Temporary Construction Easement areas. Both the contract and permit were applied for and will be held by the Federal Highway Administration for this contract. All requirements for these permits are included in the contract through the FP-03 and these Special Contract Requirements.

(e) Timber Sale Contract. A timber sale contract is required to harvest and purchase merchantable timber from National Forest Lands. (See subsection 201.06 for definitions of merchantable timber.) Approximately 15.4 ccf (1,540 cubic feet) of timber will be removed for this project having an estimated value of $650. The final volume and value will be determined when the clearing limits have been established and the timber is cruised using standard USFS appraisal methods. The contract shall be awarded and money collected prior to the start of clearing and grubbing operations. An example of the Timber Sale Contract is in the Appendices.
