From responses provided by DDRW- <br /> Tracy, we cannot determine where the values for area come from. <br /> It would also be helpful if a sample calculation was provided to <br /> better illustrate the methodology. <br /> Specific Comment 6 <br /> In addition to our comment above in General Comment 1, our <br /> concerns about fugitive dusts are over those smaller, unpaved <br /> areas and any other exposed SWMUs on the site. <br /> Specific Comment 16 <br /> It would still be helpful if the report mentions that 20 minutes <br /> is equivalent to 0. 33 hours/day. <br /> Specific Comment 20 <br /> Even though values will be presented in the Comprehensive RI/FS <br /> report, they still need to be presented in the OU No. l risk <br /> assessment in a clear manner. Specific concerns are that <br /> factors, especially absorption factors, be adequately defined. A <br /> table showing all relevant exposure parameters (e.g. , soil <br /> ingestion rates for the Comprehensive RI/FS, absorption factors) <br /> would help to present these more clearly for both exposure <br /> scenarios. <br /> II-3 <br />
