;tate of California • . Department of Health Services <br /> ,Memorandum <br /> To Donn L. Diebert, P.E. Date June 5, 1989 <br /> Senior Waste Management Engineer <br /> Subject: Review Comments <br /> From Toxic Substances Control Division <br /> 4250 Power Inn Road <br /> (916) 920-7644 <br /> Three Marley Cooling Tower Company (MCTC) submittals were <br /> received by the Department on March 30, 1989 . The documents <br /> are entitled: <br /> South Yard Storm Water Sampling Report, March 8 , 1989 <br /> Current Work Plan, Revised, March 24 , 1989 <br /> Off-Site Soil Sampling Report, March 24 , 1989 <br /> Review comments pertaining to each are presented below. <br /> SOUTH YARD STORM WATER SAMPLING REPORT <br /> The findings presented do support MCTC ' s conclusion that "all <br /> detectable concentrations of total chromium, copper, and zinc <br /> were below State drinking water standards and EPA National <br /> Ambient Water Quality Criteria for protection of human health" . <br /> There are, however, two key points which should be noted. They <br /> are: <br /> Sampling occurred subsequent to a two day storm event <br /> (ref: page 9 0£ subject report) <br /> Samples were filtered and acidified while previous <br /> analyses were performed on unfiltered/non-acidified <br /> samples (ref: page 4 0£ subject report) . <br /> Additionally, it should be pointed out that the volume of water <br /> used for simulated rain was not correlated to any particular <br /> rainfall event (see discussion on page 3 of report) . Excess <br /> dilution could have therefore been applied. <br />
