air-to-water ratios have increased to industry-accepted values and whether the system can accept more influent. 6. Appendix E, Dioxins/Furans: The reporting limits and detection limits in the introductory table do not agree with those presented in the data tables. The introductory table gives detection limits of 0.01 ug/L and reporting limits of 2.8 to 7.9 ug/L. The data tables give detection limits of 0.0 to 0.143 ng/L and does not list reporting limits. However, six of the reported concentrations are below the listed "detection limits", so it appears that the listed values may actually be reporting limits. Please clarify the reporting limits, the detection limits and the units in the dioxin/furan tables in Appendix E. MINOR COMMENTS 1. Section 1.3.1.1, Page 1-2: The first three lines at the top of page 1-2 are repeated from the previous page. Please delete these three lines. 2. Plate 1: The legend indicates that the symbol and label for the chimney drain (CD I) should be black, but both the listing at the bottom of the page and the symbol and label on the map are green. Similarly, the infiltration gallery symbol on the map is grey, the label is green and this symbol is not included in the legend. Please resolve these discrepancies. 3. Section 2.2.2, Page 2-1: The figures cited in this section (Figures 1.1-1A and 1.1-1B) do not contain the information described in this section. Please cite the correct figure. 4. Section 6.4.4.1, Page 6-4: It appears that the sentence discussing the tetrachloroethene (PCE) concentrations inadvertently cited the TCE ROD cleanup level of 0.35 parts per million by volume (ppmv) instead of the PCE ROD cleanup level. Please revise the sentence to cite the PCE cleanup level of 0.78 ppmv. 5. Table 6.4-1, Page 6-8, Other Contaminants of Concern: The table mentions "Cis-1,2-dichloroethane" in three separate places. The correct name for this chemical is "cis-1,2-Dichloroethene". Please revise the table with corrections. 3
