The seepage flow <br />continues to be clear with no evidence of cloudiness or sediment. The flow at the portal area was measured with <br />a flume and the flow is - 57.4 gpm, no substantial increase or decrease. The minimal seepage below the <br />retaining wall on the north side of the backfill appears to be the same, no visible increase or decrease. The <br />highest saturation point on the south side of the backfill (which I staked yesterday) appears to have increased by <br />approximately 3 inches, which I then re- staked. No new saturation areas were observed on the backfill or the <br />surrounding area and no slumping or earth movement was evident. I took a reading of Outfall 016 at 7:48 a.m. <br />and the metered flow is 285.4 gpm. There was no flow observed in Mr. Fontanari's irrigation ditch at 8:25 a.m. <br />Daily monitoring and updates will continue until further notice. Please contact me if you have any questions. <br />Tonya Hammond <br />Snowcap Coal Company, Inc. <br />J. E. Stover & Associates, Inc. <br />P.O.
