FROM FAX NO. :2099315186 9. 09 2003 04:10PM P2 <br /> Y <br /> f <br /> Addendum A Response <br /> Te in <br /> FOL environmental was hired to collect and analy?e wastewater as requested by the Regional <br /> Board. The lab manager and myself discussed several options including sampling all of our <br /> waste including domestic sewage,sampling directly from the septic tank, and sampling just our <br /> "Industrial waste water". We decided to collect and analyze directly the industrial wastewater. It <br /> is 1)the primary unknown, and 2)our inability to actually know what other tenants are placing in <br /> the common septic system. <br /> Method <br /> FGL uses a sample compositor that consists of a peristaltic pump. The suction side of the pump <br /> was inserted into the P-trap of the kettle floor drain. This allowed the sampling of water from the <br /> dishwashing sink and the clothes washer both of which flow into and through the same P-trap. <br /> The compositor was set up to sample every five minutes. The pump was reversed at the end of <br /> every collection cycle so that the suction tube was emptied. This insured that a fresh sample was <br /> i introduced every time. The compositor was turned on at 6:30 am and turned off after 108 <br /> samplings which was 3:30pm. <br />{ We closed off the bathroom upstream and prevented its use throughout the day so that only <br /> Process waste was collected. <br /> During that day of testing we manufactured 5 batches of chocolate sauce. Each batch uses 18.7 <br /> gallons of tap water. We washed two loads of laundry which has an estimated usage of 40 <br /> gallons per load. The sink was used to wash approximately 3 spatulas, 3 bowls, and some other <br /> mise, items that were from our chocolate arca. We also washed our filler in the sink. We also <br /> rinsed down our floor as we normally do during production. <br /> l Results <br /> Please see FGL results dated August 8, 2003 for results. <br /> r <br />
