Phone Call Log for 8ypass/Upset Reporting <br />Water Quality Control Division <br />Permits end Enforoement 5eetion <br />!II Illllllllllll I11~ <br />Entity: Mountain Coal Company -West Elk Mine <br />Pertlii No.: CD-0038771) Persons Reporting: Kathy Welt and Paige <br />Beville <br />County: Gunnison Phone No.: (970)929-2256/!(303)293-7913 <br />Start Date of Potential Upset: Mon., 20 Jan. 97 Bypass/Upset Duration: Not yet known. <br />Date 8 Tlme of Update: 27 Jan. 97, 9:20 a.m. Has this happened before: Yes <br />Probable Cause: See phone report for9~00 a.m., 2J Jan. 97. <br />Written Report to Follow: Yes <br />Comments: Welt reported that the latest estimated inFlow of fault water into the mine is 2700 <br />gpm. <br />MCC has installed three seals in the Southeast headgate "to dam up and control flow as <br />much as possible." Behind each seal is a pump, capable of pumping about 1300 gpm. <br />Pipelines were installed directly from the seals. MCC plans to tie these pipelines into <br />existing pipelines running out of the mine. This will enable Intercepting the fault area mine <br />water at the source and transporting the water to the surface without it traveling along the <br />mine floor and picking up sediment. MCC believes this water will meet TSS limitations <br />without treatment. MCC will request approval for a bypass so they can directly discharge <br />this water. The WQCD anticipates approving the bypass as long as all permit effluent <br />limitations are met. Today, they expect to make the connection from the seals' piping to the <br />mine-to-surface pipe. However, the surface lines are currently frozen and will need to <br />thaw/he thawed before the bypass piping will be complete. <br />At 3 p.m. Friday, January 24, 1997, MCC started discharging from pond MB-2R through <br />Outfa11004. MCC expects the effluent to meet permit limits. Saturday, apre-discharge <br />sample measured TSS at 44 mg/1. MCC stopped chemical treatment prior to discharge. <br />MB-2R was still discharging at the time of this phone report. <br />Sunday, January 26, 1997, Pond MB-1 started discharging. MCC expels the discharge to <br />be compliant based upon pre-discharge sample results. MCC treated Pond MB-1 with alum <br />on Saturday, using the hydro-seeder. Once MB-1 is drained, they will switch from filling <br />MB-2R to filling MB-1. <br />Recorded by: Kathleen Sullivan , <br />Date: January 27, 1997 <br />ce- Dwain Watson, DfeMd Engineer, Fidd Support Sectir <br />David BerryMlike Boulay, OMG <br />Original ro MS-3 File <br /> <br />~ i - ^7 , ~ - N auoyd B N euoYd <br />o~fiM-~e6 b, iti"~ ~ ~~ <br /> <br />~s~eNd LEIL2Il ava ~L9L a]oN xej ,tt-i®od <br />TOO f~J Q~pm/3H Q~ OBCOZ91 COC Yea 90~CT NOlf LB/LZ/TO <br />
