A. Setback Waivers:
1. Multiple setback waivers were referenced in the Additional Information submitted, however, only
one waiver was included. Please submit copies of all relevant setback waivers.
B. Soil Evaluation:
1. In the soils report, page 47 shows three ksat nests while page 48 shows four ksat nests. Please
confirm the number of ksat nests used during the soil analysis. If four have been performed, then
please provide the fourth soil profile description.
C. Engineering Calculations:
1. Within the calculations and form SFRWWIS 06-16, a dispersal area of 5,007 square feet and a
provided loading rate of 14.03 in/year. This corresponds to an average daily disposal capacity of
119.98 GPD. This is insufficient for the 270 GPD facility applied for. The loading rate provided by
the soil scientist (32.2 in/yr) gives a capacity of 275.37 GPD. Please correct the design loading rate
or adjust the design so that the minimum 270 GPD flowrate is achieved.
