FACILITY INSPECTION REPORT -5- <br /> MUSCO FAMILY OLIVE COMPANY <br /> SAN JOAOUIN COUNTY <br /> water emerging from the spring and flowing onto Musco's property was even less turbid than <br /> that in the altered streambed, <br /> I collected field measurements for EC, pH, and temperature and samples for laboratory <br /> analysis of water in the altered streambed downstream from the first sump, the spring <br /> (Photo 57), and blanket drain discharge. Tables 2 and 3 provide the,results. <br /> Table 2 <br /> Altered Streambed, Spring, and Blanket Drain Samples -- EC, pH, and Temperature <br /> Temperature <br /> Sp <br /> arn I_ e ID' Time Sample Location _EC (umhos/cm) pH <br /> 3,571 9.38 <br /> 3 3:15 PM Altered Streambed2 (3,500)3 (9.3) 18.7 <br /> 2,263 8.45 <br /> 4 3:45 PM Spring' (2,200) (8.4) 22.4 <br /> NM NM <br /> l 5 4:00 PM Blanket Drain (4,300) (7.3) NM <br /> i I Sample prefix is "HA060323" <br /> 2 Downstream of the first sump in 55 West Field <br /> 3 Laboratory result in parentheses <br /> 4 Spring upgradient of Reservoir <br /> 5 Not measured <br /> The EC of the water sample collected from the altered streambed was higher than that of the <br /> spring., and its pH was comparable to wastewater in the Evaporation South Field sumps (see <br /> Table 1). The EC of the blanket drain discharge was elevated compared to the spring. <br /> Reservoir <br /> I inspected the Reservoir (Photo 58). Hall indicated the Reservoir was nearly full and had <br /> 2.8 feet of available freeboard. <br /> 55 East Field <br /> I inspected the 55 East Field (Photo 59), which is east of the Reservoir. I observed a nearly- <br /> full sump and an erosion channel from the sump to the main drainage that traverses Musco's <br /> property (Photos 60 through 64), suggesting past spills and the threat of recurring spills. This <br /> would result in several violations of the WDRs: Discharge Prohibition A.1 (discharging <br /> wastewater to a surface drainage), Discharge Prohibition A.3 (bypass or overflow of partially- <br /> treated wastewater), Discharge Prohibition A.7 (discharge of wastewater to land application <br /> areas without a fully functional tailwater/runoff control system), and Land Application Areas <br /> Specification D_14 (manage discharge to minimize both erosion and runoff). <br /> Eucalyptus Grove Area <br /> I inspected the eucalyptus grove north of the 55 East Field and observed standing wastewater <br /> and storm water, as well as significant accumulations of erosion deposits (Photo 65). 1 also <br />
