GENERAL DEVELOPMENT NOTES

Submit an operating plan to the Contracting Officer for approval, prior to ground disturbing activities. Include bench configuration, access road location, and other operational details related to rock production in the operation plan.

Comply with applicable Federal, State and local regulations for the purchase, transportation, storage and use of explosive material, including (but not limited to) MSHA regulation 30 CFR Part 56.

Remove at least the first six inches of the top soil/rock layer prior to rock crushing activities in areas where disturbance will take place where feasible. Deposit scalped material in an area in the quarry that will remain undisturbed and not removed for use anywhere else.

Confine all crushing and pit excavation operations to the development limits and access roads, unless otherwise approved by the Contracting Officer.

Develop and maintain equipment access to the quarry floor, all benches, and the top of the quarry.

All benches utilized or produced by this project shall have a minimum width of 20 feet.

Finished faces shall have a maximum height of 30 feet, sloped at ¼ to 1 (H:V) or flatter, and scaled of loose, overhanging blocks of rock.

Blasting shall be designed, loaded and shot in such a manner as to control and retain material within the area previously disturbed by past quarry operations, as well as to minimize noise disturbance.

Conform operations to Forest Service Industrial Fire Precaution Level work guidelines.

Ensure all equipment is maintained with the required fire tools.

Outslope benches and the quarry floor to the satisfaction of the Contracting Officer.

Reduce all over size material encountered during development and excavation, and utilize in aggregate. Up to 400 CY of oversize material may be stockpiled for future use, as approved by the Contracting Officer.

Remove from Forest Service lands all operational debris including (but not limited to) garbage, rubber, metal, paper, or other objectionable material that is inconsistent with a forested setting.
