F e FACILITY INSPECTION REPORT -q- MUSCO FAMILY OLIVE COMPANY ` SAN JOAQUIN COUNTY I inspected the eastern portion of South Ridge Field and noted that the NyPa crop was sparse and stunted (Photos 34 and 35). Hall indicated that this field had been harvested once, but did not specify when. The runoff from this field is collected in a sump adjacent to a drainage (Photo 37). 1 observed a flexible hose extending from the sump to the Check Field, which contained in places standing pools of wastewater and detected a spill path to the drainage (Photo 38). Photos 39 through 42 document the recent discharge of wastewater to the Check Field. Hall verbally agreed with me when I indicated the discharge to the Check Field and spill to the drainage violates several sections of WDRs Order No. R5-2002-0148. These violations are: Discharge Prohibition A.1 (discharging wastewater to a surface drainage), Discharge Prohibition A.3 (bypass or overflow of partially-treated wastewater), Discharge Prohibition A.7 (discharge of wastewater to land application areas without a fully functional tailwater/runoff control system), Discharge Prohibition A.10 (discharging to the Check Field without prior Executive Officer authorization), and band Application Areas Specification D.14 (manage dischargE: to minimize both erosion and runoff). 1-mq„Po-id I inspected the 1-mg Pond (Photo 43). Blanket Drain, Bypass Channel, and 55 West Field inspected the dam's blanket-drain seepage collection structure (Photo 44) and the Reservoir's bypass channel (Photo 45). Groundwater surfacing from a spring upstream from the Reservoir, as well as storm water runoff from property upgradient from Musco's property, is routed around the Reservoir through an altered streambed that discharges to a concrete-lined bypass channel that discharges to the natural drainage downstream from the dam. I observed that the water discharging from the bypass channel to the drainage had a reddish-brown color similar to wastewater (Photos 46 and 47). l inspected two sumps in the 55 West Field, which is immediately north of the bypass channel, The first sump, close to the beginning of the concrete-lined bypass channel,.showed evidence of severe erosion and wastewater discharge to the altered streambed (Photos 48 through 51). walked west along the altered streambed towards the spring and observed that the reddish- brown color of the water dissipated and changed to a milky color (Photo 52). Hall indicated that the rE.-ddish-brown color was due to vegetation decomposing in the altered streambed upstream of the concrete-lined bypass channel. The second sump I inspected is close to the upper end of the Reservoir. This sump contained a tank. I Saw a deep erosion channel originating at the sump and terminating in the drainage (Photo 53). The water in the altered streambed immediately downstream of the second sump was not reddish-brown in color like that downstream of the first sump. I inspected the flow in the altered streambed upstream from the second sump (Photos 54 through 56), and noted that
