TSSI <br />9;30 aH.,, 1.0 mgA (30-day avg.TRFe) <br />Date & Time of Report: 21 Mar. 98, 10:40 am Has this happened before: No <br />Probable Cause: This is a report of potential Upset and noncompliance. A culvert runs the <br />-60 yard distance from the pond outlet to the flume, where sampling occurs. On Feb. 19, <br />a relatively recently-installed HDPE water lino broke, causing sediment to wash into the <br />culvert and through the sampling point. The cause of the break is unknown, but they <br />suspect faulty installation, possibly a weld failure. It is under investigation. <br />Written Report to Follow: Yes <br />Comment: Feb. 13 and March 4 samples showed compliance. The 'Upset" was not <br />reported earlier because the association was not made and the impact of the line break <br />not known until sample results were received and reviewed. <br />Recorded By: Kathleen Sullivan <br />Date: March 21, 1998 <br />cc- K(Int Oorh~m, DMO <br />Dl~blet EnplnNr, Fldd Support Srction <br />Orlelnal to MS-3 FN <br />
