All: Regarding the Port's proposal to remove all non-hydrologic effects on low stream flow from consideration--I am still in the process of researching Ecology's position on this issue. In the meantime, I strongly urge the Port to continue to research the quantities of water contributed to base flows from septic tank systems. This is an impact the Port identified in its December 2000 Low Stream Flow Analysis and is one that the Port has said that it will mitigate. While removal of septic tanks is generally considered helpful for - purposes of removing a source of fecal coliform it also removes water from the system which contributes to recharge of base flows. (I -- recognize that it may be difficult to quantify this amount with absolute precision.) However, flows can be an important component of water quality especially during low flow periods. Ecology regulates water quality under RCW 90.48. See particularly RCW 90.48.020. If the Port believes that the estimate of water coming from septic systems identified in Table 8 of the low streamflow analysis (66,000 gallons per day) is not correct, then I suggest that the Port work to more accurately _dentify the exact number of homes in the acquisition…
