These documents establish operating standards for the entire landfill which consists of a 97-acre parcel (primary site) and a 15 acre parcel (secondary site) . In addition, the County owns 15 acres just north of the secondary site used for a migrant farm labor camp (see sheet 3) , a 32 acre detention basin/soil borrow area, and a 20 acre soil borrow area. Approximately 112 acres are utilized for landfill operations.

The solid waste was incinerated and covered in trenches. Records do not identify the exact location and depth of these early trenches, but it is known that solid waste and cover soil was placed within the Pacific Gas and Electric (PGandE) easement that crosses the property as well as the rest of the landfill. The County of San Joaquin leased the City of Lodi property in January of 1975 and assumed the operations responsibility for both landfill areas. By this time, the solid waste was no longer being incinerated, and a cut and cover operation had been established. Compaction of the solid waste was achieved using a dozer. Solid waste trenches were excavated to approximately a 40 foot depth with the excavated material being used for cover. The County planned to add lifts of solid waste to an average design elevation of 118 feet and 2 feet of cover soil to a design elevation of about 120 feet or about 20 feet above the existing ground elevation. The landfill received solid waste from both public and contract carriers. The nature of the solid waste was typically domestic refuse, commercial refuse, tires, construction and demolition is 2
