Revegetation. The American Tree and Cement Company has -been accomplishing revegetation tasks for the past ten years in Coal Basin. Mid-Continent is convinced that the disturbed areas of Coal Basin can be revegetated for the costs quoted by American Tree and Cement in a manner that will result in success standards greater than exist on adjacent undisturbed areas. Answers to each of the MLRD concerns follow: a. Costs submitted by Mid-Continent include scarifying the hard packed areas (about 150 of the total area) and dragging other areas with chainlink fence to level out the topsoil. b. Fertilization is not needed for the soils in Coal Basin. C. The hay mulch does not require crimping or tacking. It is applied in the fall , covered all winter by snow and well imbedded in the soil during the spring snow melt. d. Hydroseeding is accomplished along with the hydromulching. Costs of hydromulching of up to 15% of the disturbed area is included in The American Tree and Cement estimate. Water is readily available for hydromulching throughout Coal Basin. e. Our cost estimates for erosion control netting is based on the actual cost of placing it on the test plots in the vicinity of the No. 4 mine pad. In our recent cal- culations for revegetating the mine bench downslopes we allow $500 per acre for the netting cost with an overall cost of $2, 093 per acre for such steep slopes . Again, American Tree and Cement estimates that hydromulching (which does not require netting) will cost $350 per acre for the 150 of the Coal Basin disturbed area that is too steep for the straw mulch. f . American Tree and Cement quoted prices are for Coal Basin which is located in the State of Colorado.
