Correspondence: From S & W: they have a new MBE subcontractor, Vantage Graphics. Don Desmaris was re-appointed to the Sewer Commission by the Selectmen. Letter from town counsel approving the draft language for the contract with Lombardo Associates. SCENARIOS At the last meeting, started to identify some scenarios—ways to treat the nitrogen problem. S &W will run a model for 4-5 scenarios to determine how well the ideas work. There were three general ideas: a. Start furthest from the water body effected b. Sewer closest to the bay (water body) for immediate results c. Sewer all the "red" areas, basically the middle of town and expand from there. What does S & W need to get started, what is needed for the MEP model? Tom Cambarari, Cape Cod Commission said it should be as fine tuned as sub watersheds; if a parcel crosses boundaries, apportion it out. Jeff said S &W, when developing the scenario, will get reasonable approximation as to whether it achieves TMDL. Tom Fudala asked if S & W will be developing a load per parcel that will then be allocated per sub watershed? Yes .teff said first option is no action, status quo. Next step, meet TMDLs, either phased or all at once and what needs to be done to achieve that. Another option, do more than meet the TMDLs or are there other areas/issues to address and incorporate into plan. The driving force is meeting the TMDLs. Easiest approach is one centralized facility, then just determine the size. Another option, use existing facilities and upgrade; make the most of what you already have (in lieu of centralized facility). Then have to decide where it's best to treat—high or low in the watershed. Then, have to decide which technology to use.
