Cochran, John N. <br />From: Cochran, John N. <br />Sent: Thursday, May 22, 2014 10:46 <br />To: kelly.morgan @state.co.us <br />Subject: CDPS CO- 0048275 potential noncompliance issue <br />Kelly <br />I discovered late yesterday afternoon after receiving the final laboratory report from ACZ Laboratories that a sample <br />collected at Outfall 004 on May 7, 2014 located at the Peabody Sage Creek Mine (CPDS Permit CO- 0048275) showed a <br />potentially dissolved selenium value greater than the effluent limit of 4.6 ug /L. The ACZ lab report shows a value of <br />potentially dissolved selenium at 7.6 ug /L. On the same day, another sample was collected at Site SSC6, which is located <br />at the lower end of the wetland established below Outfall 004, and the total recoverable selenium for that sample <br />reported by ACZ Laboratories was 3.3 ug /L, which is lower than the selenium effluent limit for Outfall 004. <br />Conditions within the watershed above Pond 004 during the months prior to the May 7, 2014 sampling were <br />characterized by seasonal snowpack and subsequent springtime snowmelt runoff as in prior years, and may be <br />considered to be an upset conditions at this pond. I will provide an explanation about this excursion when we report the <br />data in the upcoming quarterly DMR submittal for the 2nd quarter of 2014. Along with this email, PSCM considers my <br />phone message I left you this morning at 10:00 am MST to be our CPDS permit required 24 hour notification. The permit <br />also requires that we also submit within 5 days a written report. If this email does NOT fulfill that requirement, please <br />let me know, and I will follow up with a mail letter. <br />I am available today and tomorrow at my office number or mobile number (cell phone) provided in my electronic <br />signature below should you have questions or wish to talk about this excursion. <br />Thanks <br />John Cochran <br />Manager Environmental Hydrology <br />928.913.9218 (office) <br />928.286.7116 (mobile) <br />Peabe!q <br />E -mail Disclaimer: The information contained in this e-mail, and in any accompanying documents, may <br />constitute confidential and /or legally privileged information.
