The report describes sampling locations, analytical methods, and data comparison criteria to evaluate stormwater for bypass acceptance. The objective of the report is to allow discharge of uncontaminated stormwater into the bypass channel of the 84-million gallon storage pond (84-Mgal pond) or the surface water drainage feature downstream of the 84-Mgal pond. The report was submitted in response to 18 December 2002 Regional Board comments on the 25 November 2002 Report of Stormwater Bypass Criteria prepared HDR Engineering. The report addresses most of the concerns of staff, however some items were not adequately addressed in the addendum. • The last paragraph on page 1 states four stormwater sampling locations will be used, however page 4 of the report lists at least seven sampling locations: SW-1, SW-4, Culvert No. 1, Culvert No. 2, Culvert No. 3, Tailwater Collection Sump from Field 55-east, Tailwater Collection Sump from Field 55-west, Tailwater Collection Sump from South Ridge Fields, Tailwater Collection Sump from Evaporation west, south, and east. Please clarify the sampling locations and present them all on the figure preferably with a symbol indicating a stormwater bypass sampling location. Please remove extraneous details from the figure. • The report fails to describe the calibration of the field instruments as requested by the 18 December 2002 Report Resubmittal Requirements. • The report does not address the information that will be submitted to the Regional Board. As previously stated in the Regional Board's 18 December 2002 Report Resubmittal Requirement all field measurements that indicate bypass of the stormwater is acceptable shall be submitted to the Regional Board by facsimile on the same day as collection of the data and all laboratory results (performed on 24-hour turnaround) shall similarly be immediately submitted by facsimile. Please update the report to include these reporting requirements. California Environmental Protection Agency 01 Recycled Paper The energy challenge facing California is real.
