STAFF REPORT -2- RICHARD A. STAGNO STAGNO'S MEAT COMPANY SAN JOAQUIN COUNTY approximately two years ago along the northern boundary of the site, directly across from two residences. Wastewater in the treatment pond will be periodically discharged to the designated disposal area consisting of about 9-acres in the western half of the property. The wastewater will provide nutrients (nitrogen, phosphorus, and potassium) for the sudangrass, which is to be triple-cropped. A baseline soil sample from the cropland was collected and analytical results were reported in the RWD. These results will be used to determine whether the wastewater has been applied at agronomic rates, as required, and whether the manure solids may be disced into the soil prior to planting. Domestic waste will be discharged to a new septic tank and leachfield system. Rainwater from the roofed facilities (holding pens, manure storage area, and slaughterhouse) and paved areas will be collected and transported through an underground pipe to the stormwater detention pond. Depth to shallow groundwater is approximately 10 feet with an easterly flow direction. Shallow soils consist of a sandy-silt/silty-sand with at least 10 percent clay. An existing on-site supply well, near the northeastern comer of the site and downgradient of the wastewater treatment pond, will be used for process water. Analytical results reported in the RWD indicate that nitrates have not impacted the deeper water bearing zones, whereas the groundwater in the shallow zone exceeds the Primary Maximum Contaminant Level for nitrates. The RWD proposed installation of two monitoring wells, one up-gradient and one down-gradient of the cropland. The Discharger has been informed that a third monitoring well will be required to serve as an early warning detection device to protect the supply well, and as the third well to determine groundwater flow direction. The San Joaquin County Board of Supervisors adopted a Negative Declaration, with conditions, on 28 October 1996. One of the conditions of the Negative Declaration was to obtain Waste Discharge Requirements(WDRs). The City of Lathrop appealed the Negative Declaration determination based on the potential for odors emanating from the proposed site within areas slated for urbanization. However, the Board of Supervisors denied the appeal on 25 April 1995. Based on the controversy over the proposed slaughterhouse, the Tentative WDRs were provided to those that had commented on the proposal at the local level. Once comments were received, the Discharger was required to post a Public Notice which extended the public comment period from 23 August 1999 to 3 September 1999. Comments Received Comments were received from concerned neighboring landowners, including Mr. Rick Reed, Ms. Nancy Takashiro, and Mr. Larry Matlock. Copies of the comment letters and Staff's responses are attached. The major concerns of local residents are summarized as follows: c:\ckwf iles\agriculturelagwdmNstagno\staffrpt
