E-7 <br />• period, with the start of re vegetation activities corresponding to the first <br />fall season following project cessation. <br />E.4.8 Surface and Ground Water Protection <br />Potential ground water impacts could result from various activities <br />associated with the Pilot Solution Mining operation unless mitigation <br />measures are instituted. Potential ground water impacts could result from <br />well drilling and solution mining. However, since the wells will be cased <br />and cemented into the production zone, these impacts will be minimized. The <br />cement or plugging nud will ensure that all aquifers will remain isolated <br />and precludes intermingling of waters. All production wells will be <br />pressure-tested prior to production and will be monitored during production <br />to ensure against leakage. As a back-up, a monitor well will be closely <br />monitored to detect any ground water impacts. <br />Use of lined evaporation ponds will ensure that salt-laden waste waters will <br />• not contaminate either surface or ground water. Surface water quality will <br />be further protected by using runoff diversion ditches and a desiltation <br />pond. No on-site disposal of anywastes (except domestic sewage) will occur. <br />Due to the small scale and short duration of the Pilot solution mining <br />operations, negligitlle impacts are anticipated on the water rights of <br />others. Consequently, no alternative water sources are being considered. <br />Solution mining cYlaracteristically results in only minimal surface <br />disturbance. As a result, no effects on the recharge capacity of the <br />affected area are anticipated. <br />All applicable Colorado and federal laws concerning water rights, water <br />quality, and dredge and fill requirements will be properly addressed under <br />separate permitting documents. <br />• <br />THIS DOCUMENT CONTAINS TRADE SECRETS AND PRIVILEGED, CONFIDENTIAL AND <br />PROPRIETARY COMMERCIAL, FINANCIAL, GEOLOGICAL AND GEOPHYSICAL DATA AND <br />INFORMATION.
