Patterson Pass Road, Tracy, San Joaquin County CONTACT(S): Bruce Kimbrough, Operator INSPECTION DATE: 29 January 1997 INSPECTED BY: Louis F. Pratt ACCOMPANIED BY: OBSERVATIONS AND COMMENTS: This inspection was conducted in response to complaints alleging a discharge of waste water from the Lucky Dairy. The first complaint was received on 27 January. One complainant indicated that the discharge began on 23 January and that the flow has been continuous. The inspection revealed that waste water was flowing at a rate of approximately 30 gallons per minute from the west side of the waste retention area into the ditch along Grant Line Road. The waste water was flowing into an area of cropland at the intersection of Grant Line Road and Hansen Road, over a mile from the where it left the dairy. Waste water discharging into the roadside ditch at the dairy had an electrical conductivity (EC) of 3100 micromhos/cm. Waste water flowing in the roadside ditch at Hansen Road had an EC of 3J00. The reason for the discharge is that the waste pond has berms only along the north and east sides. Fields west of the pond slope toward the pond. When runoff occurs, the waste pond becomes inundated. The pond is inadequate for retaining waste water on the dairy. The inspection also revealed water ponded in the corrals. Corral runoff had discharged into the ditch alog Patterson Pass Road. A sample was taken at the point where the waste water discharged from the dairy into the roadside ditch. The sample was delivered to the Department of Fish and Game Pollution Control Laboratory for analysis. There were indications that the flow at times had exceeded 30 gpm. If the flow had averaged 30 gpm for six days the total amount of waste water discharged would exceed 250,000 gallons.
