INFORMATION SHEET RICHARD A. STAGNO STAGNO'S MEAT COMPANY ORDER NO. SAN JOAQUIN COUNTY Richard A. Stagno has proposed installation of a slaughterhouse, to be known as Stagno's Meat Company, at a former poultry facility approximately 2 miles northwest of Lathrop and 1.3 miles east of the San Joaquin River in San Joaquin County. The facility occupies 13.5 acres and will contain holding pens, slaughterhouse, manure storage area, wastewater treatment pond, stormwater detention pond, and a designated disposal area(cropland)to consist of about 9 acres. Approximately 500 animals will be slaughtered daily consisting primarily of market pigs, but also calves, sheep, and goats. Five types of wastes will be produced as part of the facility operations: • manure solids; • manured wastewater; • slaughterhouse wastewater; • whole blood; and • solid animal wastes. Manure solids from the holding pens will be scraped to a concrete lined, covered manure storage area where it will be transported off-site. In addition,manured wastewater will be produced from periodic washdowns of the pens. Slaughterhouse operations will produce the other three types of wastes: rinsewaters,blood, and solid animal wastes. Rinsewaters will be derived from animal, carcass, and kill-floor rinsings. These rinsewaters will comprise the vast majority of the wastewater, estimated to be approximately 14,500 gallons daily. Blood will be captured and stored in a tank for edible food processing and will not be discharged to the wastewater treatment pond. Solid animal wastes will consist of the discarded portions of the carcasses (offal), and the fats, oils, and greases (FOG), which are part of the wastewater produced during slaughterhouse operations. These animal liquids will be treated using a septic tank and a screened grease trap. Offal, FOG, and screenings will be not be discharged to the wastewater treatment pond but will be collected for rendering. Wastewaters from the slaughterhouse holding pens, animal, carcass, and kill-floor rinsings will be pumped to a wastewater treatment pond lined with 30-mil high-density polyethylene plastic. Where will be approximately 5 feet of separation between the base of the pond and groundwater. Wastewater in the treatment pond will be periodically discharged to the designated disposal area where sudangrass is to be triple-cropped. A baseline soil sample of the cropland has been submitted. Domestic waste will be discharged to a new septic tank and leachfield. Rainwater runoff from the roofed facilities (holding pens,manured storage area, and slaughterhouse) and from the paved areas of the site will be captured and transported through an underground pipe to the stormwater detention pond. Depth to shallow groundwater is approximately 10 feet, and the flow direction is easterly. Shallow soils consist of sandy-silt/silty-sand with at least 10 percent clay. Two monitoring wells have been proposed for installation: one upgradient and one downgradient of the cropland. Process water is obtained from an on-site supply well. c:\ckwtil s%agriculture\agwdm\stagno\stagnoinfo
