RE: Benson Brothers Pig Mesa Pit, File No. M-2004-084, Preliminary Adequacy Review f?~sPotis~
Dear Mr. Shuey:
I have enclosed the Proof of Publication and Proof of Notice to adjacent landowners and owners of man-made
structures within 200 feet. I will address the Adequacy Issues in the order that you presented them.
1. We will commit to topsoil stockpile with slopes no steeper than 3H:1 V.
2. The illustrated topsoil stockpiles will help serve as a sound and visual barrier on the east side of the
process area. Additional topsoil salvaged from the top 15 inches of the ground surface will be
stockpiled inside the west and south boundaries of the permitted azea.
3. The topsoil salvaged for use in reclamation will be primarily from the top 15 inches of Orchard City
Loam. We will salvage all the useful topsoil we can from the entire affected area. The useable topsoil
becomes thinner as we approach the south boundary, but there should be enough to replace an average
of 6 inches on reclaimed ground.
4. Spill containment structures will be needed when there aze diesel tanks on sight for crushing operations
and possibly when an asphalt plant is on site for specific jobs. These structures will consist of four foot
high walls of clay subsoil surrounding the tanks with sufficient volume to hold the entire contents of
whatever size tank is there, with enough additional volume to contain runoff from a major storm event.
The tanks with containment structures will be located in the process azea neaz the equipment they serve.
The exact location will vary as the portable equipment is relocated from time to time for more efficient
use as mining progresses.
5. We will leave a minimum of I foot of permeable gravel in place and will not excavated into the Mancos
Shale except as needed for the wash plant settling ponds. We will not discharge water from the settling
ponds or use recycled water for dust control.
6. Stormwater will be collected in a ditch at the base of the high wall and along the eastern berm and
directed to a small catch basin in the southeast corner of the process area where it can settle out sediment
and then be discharged to the existing drainage after filtering through straw bales.
