No detectable movement was expected with only <br />145,023 tons extracted, of the 242,000 tons permitted. <br />• 4.3.2 Production Wells <br />No chloride contamination has been detected in either cavity #1A or cavity #3A. Slight <br />chloride influx has been detected in cavity #4A. This influx is easily controlled with the <br />dilution created during plant operation. <br />A record of mud utilized, per BLM and EPA permit requirements, to maintain a mud pack <br />in the annulus of the production wells, is shown on Table 4-2. All production wells have <br />held surface mud/cement levels at surface throughout the year. <br />• <br />20 <br />
