Claudia Hill- St.Innocent Winery From: "Rabe, Brian T." <brian.rabe@valmont.com> To: "'chill@co.marion.or.usi" <chill@co.marion.or.us> Date: 4/5/2018 10:24 AM Subject: St. Innocent Winery Cc: "Cotton, Christopher S." <Christopher.Cotton@cascade-earth.com> Good Morning Claudia, Please share this with Matt since I don't have his email address. Did Kim Aldrich happen to talk to either of you about the sizing for St. Innocent? My understanding in speaking with the owner is that the food service to accompany the wine is intended to be very small and simple snack-size elements(a cracker with cheese,or a cracker or small slice of bread with a piece of meat,etc.). Kim clarified to me that the larger flows are associated with full meals,either catered or prepared on site. I spoke with the owner this morning and have a better understanding of the situation and offer the following alternative analysis for a potential peak day sizing: 450 gpd-150 tasters(at 3 gpd) 600 gpd-40 people at rare(a few times per year)events(at 15 gpd for meals prepared and served on site) 120 gpd-8 employees(at 15 gpd) 1,070 gpd maximum projected daily flow(potential peak) 1,350 gpd design flow(to match the existing drainfield capacity) According to the archived records,the existing system serving the house consists of 450 LF of standard serial distribution trenches. I would propose utilizing the existing system and replacement area as the base for an expanded system that would include advanced treatment. A conceptual outline of the proposed improvements is as follows: • Add a 1,000 gallon"kitchen"septic tank(like what we did at the church on Wiltse Road)and a 1,000 gallon septic tank at the new tasting room/winery building • Commingle the effluent from these tanks and the existing septic tank in a 1,500 gallon surge dosing tank with a screened pump vault and duplex pumps,controlled with timed dosing(small doses on a 24-hour schedule) • Install a 1,500 gallon per day(MicroFAST 1.5)advanced treatment system that would have a gravity discharge to the existing drainfield With you conceptual approval of this approach,we will develop a scope to submit to the owner so we can move as quickly as reasonably possible to prepare detailed plans for submittal to your office for formal review and approval. If you have any questions,do not hesitate to contact me. Thanks.
