Box 2009 <br /> Stockton, CA 95201 <br /> Dear Linda: <br /> Last October, we diposed of the purge water from the August 24, 1992 sampling <br /> event using the process described below. Since the process worked extremely well, I <br /> would like to dispose of the three drums of purge water currently located on site at 103 <br /> North E Street in the same manner. <br /> I would transport the drums of water to our Sacramento Shop at $$33 Kiefer Blvd. <br /> where we have a waste water recycle system for washing equipment which removes TPH <br /> and BTEX contamination. The waste water recycle system consists of an inclined plate <br /> seperator with polymer injection for seperating oils, fuels and silt and an activated carbon <br /> filter for removing residual TPH and BTEX constituents. The oil/fuel fraction is disposed <br /> of as waste oil through Evergreen Environmental and the spent activated carbon filters <br /> are regenerated by the supplier, Westates Carbon. Since it is a recycle system, it is a <br /> closed loop system, i.e., no water is discharged. The system has a capacity of 4,000 <br /> gallons and we normally process 2,000 gallons of waste water per day. The addition of <br /> 150 gallons to the system would not be significant. <br /> Although MW-13 is a contaminated well,water from three cleaner wells were mixed <br /> into the same drums. Therefore, it is reasonable to assume that any contamination from <br /> MW-13 has been diluted. Assuming that an equal amount of water came from each well, <br /> the Tables 1 & 2 have been prepared to illustrate the average contamination level of the <br /> three drums of water. <br /> I have also checked with the California Highway Patrol and the Department Of <br /> Toxic Substances Control, Transportation Unit regarding transportation of the water on <br /> a public highway. Both agencies said it is not a problem since the water doesn't meet <br /> the requirements for a hazardous material. <br /> Please let me know if this proposal meets with your approval so that we can begin <br />
