Mine INSPECTOR: DENNIS M. MYERS <br /> SITE LOCATION: Climax COUNTY: Lake <br /> CONTACT PERSON: Bob Ki1born TIME: <br /> TELEPHONE NUMBER: EIS UPDATE: yes <br /> INSPECTION: ROUTINE[,,, ] COMPLAINT[ J FAC J PERMIT NUMBER: <br /> HOURS: INSPECTION: 1 . 5 TRAVEL: 5. 0 REPORT: 0. 5 TOTAL: 7. C-) <br /> EMISSION POINTS SUBJECT TO NSPS: none <br /> IN COMPLIANCE: yes <br /> ---------------------------------------------------------------------- <br /> -------------------------------------------------------------------- <br /> All mining operations at the Climax mines have again been stopped, and <br /> the mine will not operate for at least the rest of this year. For this <br /> reason, no calculations are included with this report. <br /> If the mine again resumes operations, calcultions will be- submitted at <br /> that time. <br /> My inspection was of the tailings impoundments, in order to see if there <br /> is a fugitive dust problem, and to see if the dust control plan submitted <br /> by Climax has been implemented. <br /> I observed that the #1 dam face has been completely treated with Cohere.; . <br /> The #3 dam face was in the process of being treated. The #5 dam face has <br /> had access roads cut, and treatment will take place shortly. It should be <br /> noted that the control plan only called for treating the top 60 to 100 <br /> feet of the dam faces. Climax has also experimented with both Soil Seal , <br /> and Nalco, but found these two chemicals to be too expensive, so Coherex <br /> has been used. <br /> The beach areas appeared to be well treated with Cohere;; . <br /> The only emissions I observed were from the #5 dam area. These emissions <br /> were minor, and well within guidelines. Also, these emissions should be <br /> reduced in the next few weeks with the application of Coherex . <br /> To date, no complaints have been received by this office this year <br /> concerning dust from these tailings impoundments.. <br /> I feel that Climax is in compliance with our regulations and their <br /> fugitive dust control plan. <br />
