~ ~ ~• <br />~~ <br />4. Construct Acceleration Tit.ickner Plant Near Flotation 14111 - <br />Refer to Operating Plau - Item 19(f). This site was considered <br />because it caws suitable from n construction standpoint and was <br />neat the discharge point. The site was rejected because of the <br />greater pipe dista,-.ces necessary to reach this site compared to <br />the proposed site. An estimated savings of $40,000 may be <br />realized in the selection of the proposed site, rather than the <br />site near the flotation mill. <br />5. Construct Accelerateion Tlticlclter Plant Opposite the Aline Portal <br />In the narrow canyon formed by iJic~dy Gulch, site selection is <br />limited. Homestake desires a site close to the point of discharge <br />(mine portal), a site that will not interfere with the mining <br />operation, and a site that will not take a great deal of preparation, <br />thereby resulting in the least amount of environmental impact and <br />COS t. <br />Only tW0 S1teS SJere located that Islet the criteria. The site near <br />t}te flotation mill and the site opposite the mine portal. All <br />other sites Would interfere with existing operations, be too far <br />from tlce point of discharge or require a great deal of site <br />preparation. T1te site near the flotatimt mill was tejecEed <br />because of the added expense. <br />The alternative of constructing an acceleration thicl:ner plant <br />opposite the mine portal was selected to accomplish the results <br />sought in this proposal. <br />V. ENVIRON`IENTAL It4PACTS 0;: SELECTED ALTERNATIVE <br />If the proposed action is initiated, the activities that will result in <br />important environmental, social, and economic impacts include placing <br />man-made facilities on the landscape, preparation and levelling of the <br />plant site, and construction of the plant. <br />Environmental effects include soil and vegetative disturbance, minor <br />soil erosion, minor noise and air pollution, a minor increase lit water <br />quality and modification of the landscape. 1'he immediate social and <br />economic benefits of the project include employment opportnuities for <br />the construction workers and added income to the .local merchants through <br />transactions with these people. <br />Fa~.orable Effects: <br />The construction of the plant will allow llomestake to meet the <br />~• requirements of its AIPDES Permit as requires by the Colorado Dapartment <br />of F[ealth. In meeting this requirement, llomestake will be able to <br />continue its operations as planned. (APYEidDIX I.) The primary <br />- 142 - <br />
