• <br />No existing discharge sampling data exists for <br />stormwater discharges. <br />Hubbard Creek Facility (see map E8-3351R) <br />No significant materials are or have been treated, <br />stored or disposed of in a manner to allow exposure to <br />stormwater discharge. <br />No significant spills or leaks of toxic or hazardous <br />pollutants have occurred within this site. <br />Site areas <br />UH1 Topsoil stockpile - The stormwater generated by <br />this area will not potentially contain any <br />pollutants except possibly sediment. <br />UH2 Sediment pond and ventilation pad - The stormwater <br />generated by this area will not potentially <br />contain any pollutants except possibly sediment. <br />No existing discharge sampling data exists for <br />stormwater discharges. <br />C~ <br />5. <br />SWMP Administrator: The individuals within the mining <br />organization responsible for developing the SWMP and <br />assisting the Mine Manager in the implementation of the <br />plan are Jim Stover and L. Kirt Jewkes with J.E. Stover <br />& Associates, 2768 Compass Drive, STE 101, Grand <br />Junction, Co, 80506, phone 245-4101. <br />Risk Identification and Assessment: The stormwater <br />generated by this mining operation will potentially <br />contain sediment, coal fines and small quantities of <br />oil. There is one source of process water from the <br />mine dewaterinq pond. This mine water drainage is <br />pumped from its source underground to a sump <br />underground were it is allowed to settle and then <br />pumped to the mine dewaterinq pond on the surface. <br />There the water is allowed additional settlement time <br />before it is discharged into Sanborn Creek. This mine <br />water drainage is not mixed at any stage with <br />stormwater. <br />There is no outdoor storage of chemicals or equipment; <br />outdoor milling or processing activities; historic mine <br />drainage; or tailing ponds that may contribute <br />pollutants to stormwater. <br />• <br />
