INTRODUCTION Valley Ag Research has been requested by Mr. Richard Stagno and Mr. Jose Alva, Esq. to complete a Manure Management Plan (MMP) for the Stagno's Meat Company Facility located at 690 Frewert Road, Lathrop. This report complies with the requirements for a Manure Management Plan as promulgated by the San Joaquin County Environmental Health Department (PHS-EHD) and was issued under the Conditions of Approval (Item 3h). Additional information and data that pertain to this Manure Management Plan can be found in our Nitrate Loading Study for this project(NLS-07.97) dated March 1, 1998. All information contained in this report was obtained through interviews with Mr. Stagno, direct observation,the scientific literature, and chemical analyses. The subject facility was originally proposed to be an abattoir, with holding pens to stock animals before slaughtering. This proposal was accepted by the California Regional Water Quality Control Board with conditional Waste Discharge Requirements (WDRs). A facultative treatment pond was constructed for wastewater treatment before effluent was to be discharged to adjacent cropland to the south, which is owned by Mr. Stagno. The treatment pond will not be used for any purpose, but will remain as a barrier between the subject facility and residential structures adjacent to the west. Mr. Stagno now has no plans ever to develop the facility into an abattoir. This is due to the fact that he recently purchased and modernized an abattoir in Modesto, CA. It is important to recognize that the Modesto abattoir has ample holding pens whereby most of the animals to be processed are directly transported to that facility. Currently, and indefinitely, the Frewert Road facility will house animals for a short period of time which will be less than 3 days, and for most animals, less than 1.5 days. This facility will house 1.) overflow animals, 2.) animals which are transported there due to convenience, and 3.) animals to be segregated for various reasons. For example, during different festive seasons, demand for pork is above the holding capacity of the Modesto facility and therefore, a percentage of animals will be housed at the Frewert Road facility. Animals at this facility will primarily consist of small roaster(market) pigs, with a smaller number of goats, sheep and calves. Manure volume calculations are based on these animal types. The permit issued by the San Joaquin County Community Development Department-Planning Division states that the facility can house a maximum of 500 animals at any given time. The purpose of this investigation was to: ❑ Determine the volume and nutrient characteristics of the manure produced at the facility. ❑ Establish manure management procedures concerning clean-up, storage and document off-site transport. Storage area modifications, in compliance with Regional Water Quality Control Board requirements are discussed. ❑ Conduct nutrient and chemical analyses on the animal pen soils, cropland soils and domestic water supply. ❑ Discuss carcass, vector and odor controls. ❑ Demonstrate that potential on-site manure applications are within agronomically acceptable rates. ❑ Provide photographic documentation. \ Page -1- Na!!ey Ag Research
