North County RC&SL Page 11 of 64 Public Works/Solid Waste Joint Technical Document County of San Joaquin – Revised July 14, 2025 3 WASTE MANAGEMENT UNIT CHARACTERISTICS, SITING, AND DESIGN STANDARDS ___________________________________________________________________________________ The landfill development design will be in accordance with the regulations applicable at the time of construction. Lined Area 1 was designed to meet Title 14 Regulations. Areas 3 - 6 were constructed in accordance with Title 27 and Subtitle D regulations. All subsequent areas will meet the requirements for siting, seismicity, and design and construction in effect at the time of construction. 3.1 AIRPORT Title 27 CCR and Subtitle D of the federal regulations have requirements for siting new landfills near airports. In addition, existing landfills must demonstrate that the units are designed and operated so that the units do not pose a bird hazard to aircraft (see Landfill Operations, Section 6). Because the landfill is located further than five miles from the nearest airport, the regulatory requirements related to potential interaction between landfill and airports do not appear to apply. Since the landfill is not sited within a five-mile radius of any airport runway, the FAA or other airport officials were not notified of new landfill lined areas. 3.2 VOLUMETRIC CAPACITY The maximum volumetric design capacity of the site is 41.2 million cubic yards (refuse plus cover soil, not including final cover). This volume is available with the landfill height of 320 ft MSL (Table 2). 3.3 SITE LIFE ESTIMATES The landfill portion of the North County Recycling Center and Sanitary Landfill is estimated to reach design capacity by the year 2048 or later. The life of the site is uncertain, affected by refuse disposal rate and refuse density.
