CHAPTER 40 – COSTING GUIDELINES FOR INDIVIDUAL SALE ITEMS
44.22 – Surface Rock Replacement. It shall be policy on the Grand Mesa, Uncompahgre and
Gunnison National Forests to charge commensurate use surface rock replacement on all
commercial timber sales that use Forest Service controlled roads.
Costs for gravel replacement vary with the size of the crushing operation and the distance from
the pit to the application point. Our charge should be based on the average-sized crushing
operation of approximately 10,000 to 15,000 cubic yards. If the forest average cost is not
appropriate, obtain current costs from Engineering.
The following Surface Rock Replacement Cost Bulletin will be used for calculating costs for
timber sales and shall be included in timber sale packages when surface rock replacement
deposits are being collected. Document all assumptions upon which the costs are based. This
process will provide uniformity in calculating the surface rock replacement deposits.
Engineering will revise the costs annually or when new data is available.
A revised surface rock replacement deposit calculation must be prepared if an alternate haul
route is selected by the purchaser. The revision must be documented in the same manner as the
original calculation and incorporated into the contract folder.

CUBIC YARD LOSS CALCULATION
Gravel loss = 100 cu. yd./ MMCF/mile,
20 cu. yd./MMBF/mile,
or 0.100 cu. yd. /Semi Truck Load/mile.
Miles of Gravel Road = _____ mi.
Total Gravel Loss = _____ cu. yd./Unit/mile X
