Notes
A draft memorandum from Parametrix, Inc. to Keith Smith providing a scope and budget for conducting range-finding Water-Effect Ratios (WERs) using receiving water from Miller and Des Moines Creeks. The memo explains the WER methodology, references prior February 1999 range-finding studies, and recommends new tests using just receiving water in case the Port is not granted a mixing zone. Estimated costs for conducting acute Ceriodaphnia dubia toxicity tests for one or two sites are outlined in a cost table.
