Mr. Jim Stover, P.E. <br />February 11, 2009 <br />Page 3 <br />(DOW) and the most recent DOW letter for your review. This Item remains <br />to be resolved at this time. <br />57. DRMS request for additional PHC analysis and evaluation, to address potential <br />impacts associated with TR-16 proposed facilities, overlapped to an extent with <br />DOW concerns referenced in Item 52. Resolution of this item is pending input <br />from, and further discussion with DOW regarding amended PHC <br />assessment. <br />58. To ensure that the upstream surface water monitoring point (monitoring station <br />SW-1) is located above all potential surface runoff and mine water discharge, <br />please relocate the stream sampling site for SW-1 upstream of the gully that <br />enters East Salt Creek a short distance above the bridge crossing. Please ensure <br />that all future samples for water quality are collected at this location. Please <br />update Figure 4.2-2 Water Sampling Locations with the new SW-1 location. <br />Also update all appropriate maps including Figure 2.2-2 Surface Facilities <br />with the specific location of the mine water discharge point(s) to McClane <br />Creek or the ephemeral drainage that flows to East Salt Creek. <br />Please call if you have any questions. <br />Sincerely, <br />M i aAd R &1Y <br />Michael P. Boulay <br />Environmental Protection Specialist <br />C: Project File <br />Enclosures: <br />E-mail of 11/05/08 from DRMS to DOW <br />DOW letter to DRMS dated 12/22/08
