WASTE DISCHARGE REQUIREMENTS ORDER NO. 3 RICHARD A. STAGNO _ STAGNO'S MEAT COMPANY SAN JOAQUIN COUNTY 12. A septic system will be used to dispose of domestic waste. A 1600 gallon septic tank and 8000 square foot leachfield is proposed for installation in the area immediatelywest of the office. The new leachfield is approximately 120 feet from the supply well. 13. Stormwater runoff from the roofs and paved areas of the facility will be captured by raingutters and berms and will be routed through a below-ground pipe to the existing stormwater retention pond. The pond is east of the wastewater holding pond. The Discharger submitted a Notice of Non-Applicability of coverage under the National Pollutant Discharge Elimination System General Permit for discharges of stormwater. 14. The water supply for the slaughterhouse operations will be from a well located near the northeastern comer of the facility. Existing water quality data suggests that supply water is drawn from a different zone than shallow groundwater. Analytical results of a sample from the supply well were reported in the RWD to be 1734 milligrams per liter (mg/1) and<1 mg/1 of Total Dissolved Solids (TDS) and Nitrate, respectively. 15. Depth to shallow groundwater is approximately 8 to 11 feet, and the flow direction was calculated to be easterly based on three soil borings installed for the RWD. Analytical results of shallow groundwater sample from one of the borings were reported to be 3888 and 123 mg/1 of TDS and Nitrate, respectively. 16. Native soil within the upper ten feet of the subsurface is generally composed of a medium poorly-graded sandy-silt/silty-sand. Geotechnical analyses indicated that 57 percent of the soil sample is composed of fines,with approximately 15 percent clay. 17. Rainfall for the 25-year/24 hour and the 100-year/24 hour storm events are 2.7 inches and is 3.0 inches, respectively, as provided by the San Joaquin County, Department of Public Works and National Oceanic and Atmospheric Administration(NOAA). The 1996 annual evaporation was reported to be 94.6 inches (NOAA). 1. 18. The elevation of the site is approximately 10 feet mean sea level. Surface water drainage is to the San Joaquin River. The site is within the San Joaquin Delta Hydrologic Area(No. 544.00) as depicted on interagency hydrologic maps prepared by the Department of Water Resources in August 1986. 19. General land use in the area of the site is for agriculture consisting primarily of row crops, pasture and confined animal facilities. 20. The Board adopted a Water Quality Control Plan, Fourth Edition, for the Sacramento River and the San Joaquin River Basins (hereafter Basin Plan)which contains water quality objectives for waters of the Basins. These requirements implement the Basin Plan. c:kkwfilestagriculturetagwdrststagno\stagnowdrs
