Exposure to uncontrolled LFG can lead to adverse health effects due to the presence of volatile organic compounds (VOCs). Existing regulations under the Federal Clean Air Act require landfills of a certain size to install and operate a gas collection and control system, which is mainly targeted at municipal solid waste landfill emissions. Existing Sensitive Receptors Sensitive receptors are areas where individuals are more susceptible to the adverse effects of poor air quality. Sensitive receptors include, but are not limited to, hospitals, schools, daycare facilities, elderly housing, and convalescent facilities. Residential areas are also considered sensitive receptors because people are often at home for extended periods, thereby increasing the duration of exposure to potential air contaminants. The surrounding land uses are primarily agricultural with scattered single-family residences within a one-mile radius. The closest sensitive receptor is a residence located on-site about 460 feet southeast of the intersection of East Harney Lane and the North County Landfill access road (Figure 5). In addition, sensitive receptors are located along the truck haul route as close as approximately 65 feet to the centerline of East Harney Lane. Schools including Harmony Grove Elementary School and the Adelita Montessori School are also located as close as approximately 70 feet to the centerline of East Harney Lane.
