CALIFORNIA REGIONAL WATER QUALITY CONTROI BOARD CENTRAL VALLEY REGION ORDER NO. WASTE DISCHARGE REQUIREMENTS FOR MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY WASTEWATER TREATMENT FACILITY SAN JOAQUIN COUNTY The California Regional Water Quality Control Board, Central Valley Reps on, (hereafter Regional Board) finds that: 1. Musco Family Olive Company and the Studley Company (hereafter jointly referred to as "Discharger") submitted a Report of Waste Discharge (RWD), dated 30 April 2002, for land application of industrial wastewater. Additional information was submitted on 24 June 2002. 2. Waste Discharge Requirements (WDRs) Order No. 97-037, adopted by the Regional Board on 28 February 1997,prescribes requirements for Musco Olive Products and the Studley Company. The RWD was submitted to revise the existing WDRs, and was required due to the increase in the discharge quantity and quality. The Discharger submitted an R JVD January 2000 which was deemed incomplete. The resulting enforcement activities that ar-- described below resulted in submittal of the 30 April 2002 RWD. 3. The facility is at 17950 Via Nicolo,Tracy,in Section 34, T2S, R4E, and Sections 3 and 4 of T3S, 11 U R4E,MDB&M, as shown in Attachment A, which is attached hereto and made part of the Order by reference. The Studley Company owns all of the parcels (Assessor's Parcel Numbers 209-11- 18, 209-11-31, 209-11-32, 251-32-08, 251-32-09)used for processing and/or land application. Musco Family Olive Company operates the facility. 4. Wastewater generated at the facility is regulated by two separate WDRs. Order No. 96-075 regulates the two surface impoundments regulated under Title 27 of the California Code of Regulations, §§20005 et seq., (hereafter Title 27) that are used to store concentrated brines. Order No. 97-037 regulates the less concentrated wastewater which is applied to land. This WDR update only applies to the less concentrated wastewater. 5. As set forth in the detailed findings that follow,the Discharger proposes to continue the discharge n /] of wastes to land, and hence the groundwater,that are herein classified as "designated waste" and \\\`//// subj ect to full containment under Title 27. However, the discharge of such designated waste to V land is not allowed under WDRs No. 97-037, and is also not allowed under this updated Order. The following findings analyze the RWD for requirements under which an exemption from Title 27 may be granted and, as intended by the RWD, for the conditions under which waste may be discharged to a land treatment unit, followed by infiltration to groundwater. z BACKGROUND 6. Musco Family Olive Company processes approximately one-half the total table olive crop in the State. In 1999,the Discharger acquired an olive packing facility in Visalia, closed that facility,
