Poway Landfill (Inactive) - Former Solid Waste Landfill in Poway, California

Poway Landfill (Inactive) is a former solid waste disposal site located in Poway, San Diego County, California. The facility is classified as a landfill and is currently listed as operational, though its name suggests it may be inactive or in post-closure care. It is situated at 14900 Block of Poway Road, within a suburban area of Southern California. As a landfill in California, the facility operates under the regulatory framework of the US EPA's RCRA Subtitle D for municipal solid waste landfills, as well as California's stringent state regulations, including Title 27 of the California Code of Regulations. These rules govern landfill design, operation, closure, and post-closure care, including groundwater monitoring, leachate management, and landfill gas control. The facility's NAICS code 562212 indicates it is a solid waste landfill, though no specific tonnage or capacity data are available. The environmental significance of this facility lies in its long-term management of legacy waste. Inactive landfills require ongoing monitoring of groundwater and landfill gas to prevent contamination and methane emissions. The site's location in a semi-arid climate with proximity to residential areas underscores the importance of proper closure and post-closure care to protect public health and the environment.

The Poway Landfill is located in a semi-arid region of Southern California, where water resources are scarce and groundwater protection is critical. Inactive landfills pose risks of methane leakage and groundwater contamination from leachate. The facility's proximity to residential areas in Poway necessitates careful management of landfill gas and runoff to minimize community exposure. California's regulatory framework mandates long-term monitoring and maintenance for closed landfills to mitigate these environmental impacts.
