Please forward me blank <br />DMRs in digital form (use bwatterson@peabodyenergy.com). I have put together a new DMR for the new metal <br />parameters for now. <br />Outfall 022A/022X (site 1 SP) did not flow in January, and started flowing the last week in February. The site flowed each <br />week of March. Site 003A/003X (5D) flow was observed during each week of the period. There were two exceedances at <br />003A the first week of January. The 30 day average for TSS was 45 mg /L (versus limit of 35 mg /L) and the 7 day max was 83 <br />mg /L (versus limit of 70). This was probably the result of the pump being off and restarted, which may have flushed material <br />from the sedimentation ponds. Subsequent TSS results were 8, 14, 11, < 5, and < 5 mg /L for the remainder of the quarter. <br />Outfalls, 004A, 007A, 009A, 011 A, 012A, 013A, 014A, 015A, 016A, 017A, 018A, 019A, 020A, 021 A, 023A, and 024A/024X, <br />along with Site 3001, did not discharge during this period. In order to reduce the amount of paper work, the following <br />certification will be substituted for the actual DMR forms to cover the outfalls, which did not discharge. <br />CERTIFICATION <br />I certify under penalty of law that I have personally examined and am familiar with the information submitted herein; and <br />based on my inquiry of those individuals responsible for obtaining the information, I believe the submitted information is <br />true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the <br />possibility of fine and imprisonment. See 18 U.S.C. § 1001 and 33 U.S.C. § 1319. (Penalties under these statutes may <br />include fines up to $10,000 and /or maximum imprisonment of between 6 months and 5 years.) <br />Brian A.
