Soil Suitability/ Nitrate Loading Study Addendum Letter Irerracon <br /> Nostra Vita Winery Lodi, California <br /> May 20, 2019 Terracon Project No. NA197023 <br /> Terracon reviewed the EHD online permits for the site address of 1150 W. Turner Road. The <br /> following permits were available on the EHD website for the site address. <br /> Table 2. <br /> Summary of On-Site Septic Permits. <br /> Leach <br /> Tank Size Leach Line Line Seepage Pits, <br /> Address Permit# Type Sumps,Filter <br /> (Gallons) Quantity Length <br /> Beds, Other <br /> (Feet) <br /> SR0050124 Destruction --- --- --- — <br /> 1150 W.Turner Road SR0055802 New Install 1,600 4 84 --- <br /> Based on a review of the permit history, the site is equipped with a 1,600-gallon septic tank with <br /> four 84 foot long leach lines. A septic system (size not reported) was destroyed in 2007. There <br /> were no repair permits found for the address. Copies of the permit history are included in the <br /> Attachments. <br /> Based on interviews with Ms. Bloudoff-Indelicato, in general, the existing wine tasting room <br /> operates year-round, Monday, Thursday, Friday, Saturday, and Sunday from 11 am to 6 pm with <br /> a single shift work day and includes up to 5 employees, up to 25 daily visitors, and 30 single day <br /> events each year with up to 120 people in attendance per event. The proposed 3,750 SF winery <br /> production building will operate year round, Monday through Friday, between 8 am and 5pm with <br /> up to 3 employees per day. <br /> To estimate the wastewater flow for the facility, Terracon considered the standard and peak <br /> operational hours, shifts, number days of operation per year, number of employees, number of <br /> visitors, and special events. The maximum (max)daily flow rate and average daily flow rate were <br /> calculated for each building. <br /> Expected Maximum Daily Flow Rates (# People per day x# Effluent gpd) <br /> The max daily flow rate for the existing facility is 650 gpd (5 employees x 30 gpd + 25 visitors x <br /> 20 gpd). The proposed wine production building is anticipated to add an additional 45 gpd (3 <br /> employees x 15 gallons per day). The special events are anticipated to add 2,400 gpd (120 people <br /> x 20 gpd) per event. Therefore, the maximum daily flow rate for the facility is anticipated to be <br /> 3,095 gpd. <br /> Based on a review of the California Department of Water Resources, Groundwater Information <br /> Center Interactive Map, depth to groundwater is anticipated between 30 and 40 feet bgs. The <br /> groundwater flow direction and the depth to shallow, unconfined groundwater, if present, would <br /> likely vary depending upon seasonal variations in rainfall and other hydrogeological features. <br /> Without the benefit of on-site groundwater monitoring wells surveyed to a datum, groundwater <br /> depth and flow direction beneath the site cannot be directly ascertained. <br /> Based on a review of California State Water Resources Control Board GAMA website, there were <br /> Responsive ` Resourceful v Reliable 4 <br />
