Dear Wayne:

As a .result of our discussion and a phone conversation with Mr. Brad James
of the Colorado !'fined Land Declamation Board, I would recommend the following
items be added to the permit applications for the Koenig, David Ranch and
Pierce pits.
DAVIS RAt•;CH and KOEPiIG PITS
1. Asa result of the mining process, we anticipate that there will be some
uneveness or irregularity in the bottom and banks of the pits. Curing the rec-
lamation process, many o: these depressed areas and irregularities should be pre-
served to present a more natural habitat for fish and wildlife.
2. As indicated on the Extraction Plan Paps and Reclamation Plan Maps, a bar-
rier strip shall be maintained between the pit and the river. As a general
rule the barrier strip shall have a minimum width of 100 feet.
3. Topsoil shall be stripped from all areas to be affected by the mining op-
eration, stockpiled separate from other material, and protected against erosion.
During tale reclamation operation following filling and grading, topsoil will be
spread over all affected areas to a minimum depth of six inches.
4. The seeding rates and mixtures, as recommended by the Soil Conservation Ser-
vice, shall be as follows:
Common PJame Var;ety % in Stand lbs. *PLS/Ac. in Mixture
Sand bluestem Elida 20 3.2
(Andropogon haliii)
Side oats grams Vaughn 15 1.4
(Bouteloua curtipendula)
Prairie sandreed * 20 1.3
(Calamovilfa iongifolia) -
*Seed source from within 150 miles of planting site is recommended.
