Macdoel Landfill - Dorris, California Solid Waste Management Facility

Macdoel Landfill is an operational solid waste facility located in Dorris, California, within Siskiyou County. As a landfill, it serves the local community by managing municipal solid waste in a region characterized by rural and agricultural land use. The facility is part of the broader waste management infrastructure in Northern California, addressing the disposal needs of the area. The landfill operates under the regulatory framework of the United States Environmental Protection Agency (EPA) RCRA Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act (CAA) landfill gas rules. California imposes additional state-level requirements, including strict leachate management and groundwater monitoring protocols. The facility's NAICS code 562212 indicates it is a solid waste landfill, typically handling a range of non-hazardous waste types. Environmental considerations for Macdoel Landfill include landfill gas generation and methane leakage, which are managed through gas collection systems to reduce greenhouse gas emissions. Leachate management is critical to protect local groundwater, given the rural setting and potential proximity to water resources. The landfill's location in Siskiyou County, near the Oregon border, places it in a region with sensitive ecosystems, requiring careful operational oversight to minimize community and environmental impacts.

Macdoel Landfill is situated in a rural area of Siskiyou County, California, where groundwater protection is a key environmental concern. The facility must manage leachate to prevent contamination of local aquifers, which are vital for agriculture and domestic use. Landfill gas, primarily methane, is generated from decomposing waste; proper collection and flaring or energy recovery systems are essential to mitigate greenhouse gas emissions. The site's proximity to natural habitats necessitates careful monitoring of wildlife and vegetation impacts, though specific ecological designations are not confirmed.
