Mr. George Lockwood <br /> September 7, 2004 <br /> Page 2 <br /> City Responses to Regional Board Staff's General Comments on Report <br /> Comment 1: The report is not certified by the Discharger as required by the <br /> Standard Provisions. <br /> City Response: Acknowledged. Future reports will be certified. <br /> Comment 2: Specific Conductivity and Total Coliform Organisms are groundwater <br /> constituents that were measured for the groundwater-monitoring program. <br /> However, it appears that these data have been overlooked. No mention is made as <br /> to why these constituents have been excluded from the status report evaluation. <br /> City Response: The evaluation of Specific Conductivity (Electrical Conductivity) <br /> and Total Coliform Organisms levels were not included in the evaluation as these <br /> constituents were not highlighted for evaluation as part of the early dialog with <br /> Regional Board staff nor as part of the dialog associated with the approved <br /> workplan. <br /> The City has evaluated the Specific Conductivity and Total Coliform Organisms <br /> data. Those evaluations will be discussed later in this letter. <br /> Comment 3: The report does not present constituents cumulative data in a tabular <br /> format for easy review. <br /> City Response: Tabular data was not presented in its entirety because it is <br /> quite voluminous, and the City felt that for the purposes of the Status Report, <br /> graphical presentation of the data was the best approach to foster an <br /> understanding of field conditions. <br /> A set of tables containing the groundwater monitoring data is enclosed. A <br /> significant amount of groundwater elevation data has been collected since <br /> August 2001. Not all of this data is included in the tables because of the volume. <br /> If requested, the data can be provided digitally. <br /> Comment 4: Groundwater flow gradient and direction are not calculated or <br /> graphically presented. The calculation and presentation are required by the <br /> Monitoring and Reporting Program No. 5-00-031. <br /> City Response: Groundwater flow gradient, flow velocity, and direction of flow <br /> were discussed on Pages 4 through 8 of the Status Report. Due to the nature of <br /> the groundwater levels in the area, it is not possible to definitively state a single <br /> flow gradient or direction of flow. However, the discussion on Pages 4 through 8 <br /> does provide a summary of the conclusions that the data supports. Figure 2 in <br /> the Status Report illustrates the average groundwater elevations for the period <br /> August 2001 through June 2003. <br /> Enclosed with this letter are supplemental groundwater elevation contour figures <br /> for the months of July 2003 through May 2004. Also enclosed is a figure <br /> showing the average groundwater elevation contours for the period August 2001 <br /> LLOCKW OOD_N PDESPERMIT.DOC <br />
