20. The up and down at ream fill slopes will be riprapped with a well graded mixture of rock sizes containing no material greater than 2 feet or smaller than 3 inches. The ratio of maximum to minimum dimension of any rock shall not exceed 6:1. 21. Drivable waterbara or "thank-you-mama" will be installed at approximately 125`foot intervals on grades above 10 percent, 250 foot intervals on_ grad-- ee o~-~ to 10 percent, and 500 foot intervals on 1 to 4 percent _ grades. Placement of a culvert will-take-the place of a vaterbat. 22. Drivable waterbars and culverts will be installed and approved prior to moving the drilling rig onto the location. 23. Trash will be confined in a covered container and hauled to an approved landfill. Burning of waste or oil is not approved, and spoil material will be kept onsite for recontouring. 24. The Grand Junction Resource Area Manager will be notified at least 24 hours prior to commencing reclamation work.= ~c, 25. The disturbed areas will be seeded with the following mixture. Application rates are for pure, live seed (PLS). Seed tags must be submitted_to the area manager within 30 days of seeding, „j_.- ~`~ / 'G S ecies Application Rate lbs/Acre/PLS The seed mixture provided in the South Leases Exploration Plan. 26. Prepare seedbed by contour cultivating 4 to 6 inches deep. Drill seed 1/2 to 1 inch Seep following the contour. In areas that cannot be drilled, broadcast seed at 1.5 times the application rate and cover 1/2 to 1 inch deep with a harrow or drag bar. Seeding must he completed after September 1 and prior to October 15. 27. Restore the access road and all drill sites to approximate the original contours. During reclamation of the site, push the fill material into cuts and un over the backslope. T,eave no depressions that will trap water or form ponds. Distribute topsoil evenly over the location and seed according to the above seed mixture. The access road and location will be ripped or disked prior to seeding. L _,,:~ The area is considered to be satisfactorily reclaimed when: A. Soil erosion resulting from the operation has been stabilized. B. ,A vegetative cover at least equal to that present prior to disturbance and a plant species composition at least as desirable as that present prior to disturbance has been established. Any additional work will be required until these conditions are satisfied.
