GOLDSEARCH RESOURCES INC -y III III^~~IIIIIII III ~ sss March 2, 1994 Mr. Bill York-Feirn RECEIVF~ Division of Minerals and Geology 1313 Sherman Street, Room 215 MAR p Denver, Colorado 80203 3 1994 RE: BATES HUNTER WATER TREATMENT FACILITY Cri,r„nc~~'iint~r~l~x. Dear Mr. York-Feirn: Enclosed are three exhibits that provide information that you requested regarding the Bates Hunter water treatment facility. The first exhibit is a raw water analysis of the Bates Hunter mine water. As indicated the untreated mine water meets all secondary and most primary drinking water requirements. The highest constituent is 28 ppm iron. The :second exhibit is a calculation of the amount of sludge that will be generated by the Bates Hunter water treatment plant. Item 7 indicates that 20 to 30 pounds per hour of dry sludge will be generated or 65 to 70 pounds of wet sludge will be generated per hour at an operational rate of 300 gpm. The mine makes 125 gallons of water per minute which, after dewatering, will be the operational rate of the water treatment plant. The t:hirtl exhibit is a TCLP extraction test that we conducted for the elements that the EPA requires when testing hazardous waste. I have included a copy of the Toxicity Characteristics (TC) Rule Notice which lists the TCLP limits for metals (See Table 1). All TCLP tests for the constituents tested detected less than EPA action levels for sludge. As I indicated, this was a small test and a larger sludge sample will be required before a final TCLP metal extraction test can be run c>n the sludge. The large sample test results will be used to determine the characteristic of the sludge, i.e., hazardous waste or not. If the sample test results indicate that the sludge is hazardous then the sludge will be disposed of in a licensed hazai°dous waste disposal site. If the TCLP tests indicate that the sludge is not characterized as hazardous waste we will dispose of the material in an approvetl site such as Solution Gold which is located in Gilpin County. We currehtly anticipate shipping the sludge to the appropriate disposal site in 55 gallon drums. The shipment of hazardous waste is regulated by EPA and state regulations that require licensed hazardous waste drivers to transport the sludge in vehi~ales that have special safety requirements.
