Page 2-3 SECTION 2-SITE OPERATIONS PLAN 2.1.4 Scale House Operations All vehicles entering the landfill will be stopped at the scale house. Vehicles will be weighed and then be directed to the current active area of the landfill. The scale house attendant will visually screen incoming loads for prohibited wastes (see below). 2.1.5 Waste Acceptance and Screening It is the intention of the City of Stockton to allow certain types of solid waste to be disposed at the Austin Road landfill, and to exclude from disposal other types of solid waste. The Austin Road landfill is to be operated in conformance with the SRRE, as adopted by the City. 2.1.5.1 Prohibited Wastes Specifically, the following wastes are prohibited from the landfill: a Sewage Sludge Approximately 13,000 tons per year of sewage sludge is generated by the City Regional Wastewater Control Facility. The sludge is dried to a minimum 50 percent solids and stockpiled at the generating facility for future agricultural land application. The City's SRRE proposes that a sewage sludge composting program be developed in the mid-term I lanning period at a site to be determined. Therefore, sewage sludge is not accepted at the Austin Road Landfill. a Asbestos Friable (i.e., readily crumbled) asbestos in the wastestream is considered a serious health hazard and requires special handling and disposal, and therefore is not accepted at the Austin Road landfill. Waste asbestos generated in Stockton must be manifested and taken to a waste disposal facility permitted to accept asbestos. a Tires Until June 1991, the Austin Road Landfill accepted used tires from commercial haulers, and the tires were disposed of at the active face of the landfill. However whole tires pose special handling and disposal problems such as collecting rainwater (and serving as breeding grounds for vectors), they are a fire hazard, and they tend to "float" to the surface of the landfill, causing 'discontinuities in the landfill cover and differential settlement. State regulations prohibit the landfilling of whole tires. They must first be volume reduced by shredding, splitting, chopping, etc. In addition, waste tires will be subject to new regulations in the State of California with the adoption of Assembly Bill AB 1843. The general requirements of this law provide for State procurement of retreaded tires, the increased use of waste tires in recycled products, a required reduction of 25% in the C,-.v o'3:a:<ion R.W.Back and Associates 1811.002
