<br />~~. ~ <br />3.1 Hazel A Adit <br />The Hazel A adit is owned by Mr. Mazk Steen and is not within the permit area. <br />Infiltration ground water is currently stored behind a coffer dam approximately 50 feet <br />from the entrance of the Hazel A adit where it awaits pumping to the mill, and ultimately <br />the tailings pond. The water quality in the adit is appropriate for land application, and has <br />been approved for such within the permit area (Sorenson, 1996a). Water quality data for <br />the Hazel A adit are presented in Table 1. <br />As part of the mill closure, the water currently in the Hazel A adit will be pumped to the <br />tailings pond evaporation and land application systems until the adit no longer contains <br />sufficient water for pumping, and the coffer dam and all Franklin equipment and piping <br />will be removed. Operation and maintenance of the Hazel A adit will then be the <br />responsibility of the owner, Mr. Mark Steen. <br />3.2 Mill Building and Contents <br />All mining and milling equipment will be rinsed and removed from the mill building and <br />removed from the site. Approximately 100 to 200 tons of grinding and flotation tailings <br />currently reside in a thickening tank in the building. These tailings will be tested for acid- <br />base potential (ABP) and added to the tailings pond. <br />Upon removal of all equipment and tailings from the mill building, the building will be <br />thoroughly cleaned. All significant dirt, dust and other residues will be removed by a <br />combination of sweeping and washing with clean water. All wash water will be disposed <br />of in the tailings pond. The building will remain on site and in tact. Zoning for <br />industriaVcommercial uses will be requested from Boulder County upon completion of the <br />reclamation operations. <br />3.3 Tailings Pond <br />The tailings pond will be drained of water by a combination of evaporation and land <br />application of the pond water. The existing evaporation and land application systems will <br />be used at the currently permitted rates until the water level is below the level where water <br />can be pumped from the pond. <br />Approximately 1,500 cubic yards of tailings are presently in the pond which has an <br />estimated capacity of 2,500 cubic yards. The tailings have been tested for ABP, and are <br />slightly acid generating. Portland cement or fly ash will be mixed with the tailings <br />(including those transferred from the mill building) to neutralize any potential acid <br />generation and stabilize the tailings. The resulting mixture will be confirmation tested for <br />ABP. <br />i V n6a~ro~ID mUeEaidoc. i o. ~ ast <br />2 <br />
