Jeff Colombini / Brady Whitlow - 2 - 26 July 2013 Corto-Olive typical constituent concentrations. The two types of wastewater generated at the facility were as follows: • Low strength wastewater from olive washing and routine plant sanitation activities is directed into floor drains, piped to a 2,000-gallon underground storage tank (UST), pumped to a 10,000-gallon storage tank equipped with totalizing flow meters, and subsequently applied to an 85-acre cherry orchard LAA. Under the 2010 NOA, this wastewater may be applied to land. • High strength wastewater consisting of clean-in-place solutions, boiler blowdown, and any boiler feed water treatment residuals (such as ion exchange brine) is directed by floor drains to a second 2,000-gallon UST. Under the 2010 NOA, this wastewater could not be applied to land and was disposed of at the East Bay Municipal Utility District wastewater system or equivalent facility. Olive processing activities produce some residual solids including leaves and stems, which are separated prior to olive milling, and pomace (the pulpy residue that remains from olive pressing). The combined residual solids are land applied to a 35-acre olive orchard, or disposed off-site at a landfill, compost facility, or as animal feed. Land applied solids are applied with spreaders and then disced into the soil at approximately three to five tons per acre. Residual solids are not applied 24 hours before, after, or during a storm or when soil is saturated. At the time of the 2010 RWD, the clean-in-place (CIP) process consisted of flushing equipment and olive tanks with a 1-2% potassium hydroxide solution followed by rinsing with acetic acid and water. Recently, Corto-Olive converted the CIP process to use a hot water rinse and a 1-2% solution of monoethanolamine and 2-butanol (Chemco 64) for tank and equipment cleaning, and no longer uses the potassium hydroxide and citric acid solutions. Laboratory analysis of a CIP process wastewater sample collected in May 2013 demonstrated that the salinity of CIP process wastewater is consistent with low strength wastewater from olive washing and routine plant sanitization activities. Based on the recent change in the CIP process, CIP wastewater using the Chemco 64, or equivalent solution, can be included with other low strength wastewater generated from olive milling activities and discharged to the cherry orchard. Boiler blowdown and boiler feed water treatment residuals (such as ion exchange brine) must continue to be separated out and transported off-site to a permitted disposal facility. AMENDED NOTICE OF APPLICABILITY Based on the information submitted in the amended RWD, the discharge satisfies the general and specific conditions of Resolution No. R5-2009-0097 for the inclusion of Clean-In-Place wastewater generated at the site. Order No. R5-2009-0097-0028 is hereby amended to reflect a change in wastewater discharge quality at the facility. A copy of the Order is enclosed and it is also available on the internet at: http://www.waterboards.ca.gov/centralvalley/board decisions/adopted orders/#waivers Please familiarize yourself with the contents of the Order including the discharge and monitoring requirements. The facility must be operated in accordance with the requirements contained in the Order and with the information submitted in the RWD and additional information submitted to complete the RWD.
