These wastes are classified as 'non-hazardous solid waste' or 'inert waste' using the criteria set forth in Chapter 15. The discharge rate is approximately 80 cubic yards per day. GEOLOGY 9. The soils immediately underlying the landfill are lenticular units composed of clay, silt, and sand with minor amounts of gravel. 10. Published information indicates that no active faults occur within the site. The maximum probable earthquake for faults nearest the site range from 6.2 to 6.8 magnitude (Richter scale). The anticipated maximum ground acceleration is 0.4g. SITE DESCREPTION 11. The first water-bearing formation is approximately 30 to 45 feet below the base of the landfill. The hydraulic gradient is generally to the north-northeast toward pumping depressions northwest and east of Stockton; ground water flows at a velocity of at least 5 feet per year, but not more than 40 feet per year. 12. Land within 1000 feet of the facility is zoned residential within the City of Stockton's jurisdiction. Van Buskirk Park is adjacent to Walker Slough north of the site. 13.
