The facility is located at 9240 S. Harlan Road, <br /> French Camp and will be owned and operated by French Oils, LLC. At this time, we have <br /> determined that Waste Discharge Requirements are not necessary, as described below. <br /> The products that will be produced at the site and the waste streams that result from the <br /> processing are described in the Water Quality Management (WQM) report (attached), <br /> provided in a 27 February 2009 e-mail from Mike Seley to Regional Water Board staff <br /> member, Timothy O'Brien. <br /> The oil extraction process consists of the following: corn germ is delivered in bulk shipments, <br /> the corn germ is fed via auger into a dryer-conditioner; the product is heated by a closed loop <br /> system with steam provided by a boiler; heated corn germ is fed into an expeller where oil is <br /> separated from the germ meal; ail is pumped into settling tanks for cooling and settling, it is <br /> later pumped into holding tanks; corn germ is stored on shop floor for cooling, it is later <br /> shipped as livestock food. If other oils are processed,in-the future (e.g. safflower oil), the <br /> equipment would be cleaned by flushing the oil and tanks with the new product. The mixed <br /> product would be marketed as mixed oil or sold for biodiesel production. <br /> According to the WQM report, small amounts of wastewater will be generated in producing <br /> the corn oil. The waste streams that will be regularly generated consist of boiler feed water <br /> treatment residuals and boiler blow down. As a contingency, the WQM identifies oil line and <br /> oil tank cleaning residuals; however, the equipment manufacturer has stated such cleaning is <br /> not recommended. <br /> The WQM report states each waste stream will be handled as follows: <br /> E Boiler feed water conditioning: To protect the boiler from corrosion, water softening will <br />€ be performed.
