Please <br />be aware that the results are based on a sample dilution of 50%, therefore results should <br />be doubled. The sample is diluted to preserve the sample and prevent precipitation of <br />solids (bicarb). The "average soluble salt content" is measured in Total Dissolved Solids <br />or on the ACZ report as "Residue Filterable (TDS) @ 180C" and concentration was <br />57,000 (times two) equals 114,000 mg/1(or ppm). Because of the high concentration of <br />sodium bicarbonate (TDS) the spill was immediately removed from a bare subsoil area <br />and placed in a active mud pit designed for high TDS drilling fluids. Because no "soil" <br />was contaminated the subsoil was from an area already disturbed, the material was <br />excavated and placed in the mud pit. <br />NSI will report all spills, even though product produced at the NSI mine site is not toxic <br />or hazardous, to the Division of Minerals and Geology and the BLM within 30 days, per <br />BLM regulation. NSI will fax the Minerals Program Supervisor at the DMG, 303-832- <br />8106 with a call back number, (970- 878-3674 ext.l 1), and contact person, (Ed Baker) <br />within the 30-day time frame. <br />This letter addresses atl the questions in your letter dated January 7, 2004. If there are <br />any additional questions please contact me. <br />Si(nc~er~ely, <br />Lam->~ <br />Ed Baker, REM <br />EHS Manager <br />Cc: BLM, David Luzmoor <br />
