i <br /> CENTRAL VALLEY REGIONAL WATER QUALITY CONTROL BOARD <br /> FACILITY INSPECTION REPORT <br /> 31 October 2006 <br /> DISCHARGER: Musco Family Olive Company <br /> FACILITY: Wastewater Treatment and Land Disposal Facility <br /> LOCATION & COUNTY: Tracy, San Joaquin County <br /> CONTACT(S): Mr. Ben Hall, Technical/QA'Manager 209-836-4600 <br /> INSPECTION DATES/TIME: 23 March 2006 <br /> INSPECTED BY: Mr. Hossein Aghazeynali, WRC Engineer <br /> ACCOMPANIED BY: Mr. Dennis Leikam, Technical Specialist with Musco <br /> Mr. Todd Del Frate, Engineering Geologist with Regional Water <br /> Quality Control Board (Sacramento Office) <br /> BACKGROUND: <br /> Musco Family Olive Company (hereafter Musco or Discharger) processes black olives at its <br /> facility near Tracy. The olives are received, stored in an acetic acid solution, cured in sodium <br /> hydroxide (lye), rinsed several times, pitted, and canned in a brine solution. Waste Discharge <br /> Requirements (WDRs) Order No. 96-075 regulates the discharge of high salinity wastewater <br /> i (e.g., flotation brine, softener regeneration, spent lye, and boiler blowdown) to surface <br /> impoundments (Title 27 ponds). WDRs Order No. R5-2002-0148 regulates the discharge to <br /> i land of lower salinity wastewaters (e.g_, carbon-neutralized lye rinse water, dissolved foam <br /> from the stirring of olives in acetic acid, storm water). Lower salinity wastewater is discharged <br /> first to a 1-million-gallon settling pond (1-mg Pond) then to an 84-mg storage reservoir <br /> (Reservoir) then applied via sprinklers to various fields comprising the land application areas. <br /> Runoff from these fields of applied wastewater and storm water is returned to the Reservoir. <br /> OBSERVATIONS AND COMMENTS:' <br /> We met Hall and Leikam onsite. The weather was sunny but cool with some breeze. Del Frate <br /> inspected the Title 27 ponds and I inspected the land application areas. I observed two tanks <br /> near the north side of Title 27 ponds (Photos 1 and 2) in which chemicals are stored for use in <br /> treating surface water from the California Aqueduct for use as the Plant's process water supply. <br /> Evaporation South Field and Drainage By 1-580 Culvert <br /> I inspected the Evaporation South Field (Photo 3) and the adjacent drainage that flows through <br /> a culvert under Highway 1-580 (1-580). Leikam reported that this field was planted with NyPa in <br /> October of 2005. However, I did not see significant growth in this field (for example, Photo 4). <br /> There is a storm water and wastewater runoff ditch that terminates in a sump that is adjacent <br /> to another sump (Photo 5). The water in the first sump was darker in color (Photo 6) than the <br /> water in the second sump (Photo 7). 1 observed an erosion channel extending from the <br /> PICTURES TAKEN BY: Todd Del Frate, Engineering Geologist, and Hossein Aghazeynali, WRC Engineer <br /> PICTURE DATE: 23 March 2006 <br /> TIME: 10:.00 A.M.430 P.M. <br /> 1 <br />
