Peck Road Gravel Pit Landfill - Monrovia, California Solid Waste Management Facility

Peck Road Gravel Pit Landfill is an operational solid waste facility located at 128 E Live Oak Road in Monrovia, California, within Los Angeles County. As a landfill, it plays a key role in managing municipal solid waste for the surrounding communities in Southern California. The facility operates under the regulatory framework of the US Environmental Protection Agency's RCRA Subtitle D, which governs municipal solid waste landfills, and the Clean Air Act's landfill gas rules. Landfills in California are also subject to state-specific regulations from CalRecycle and local air quality management districts, ensuring proper landfill gas collection and leachate management. Given its location in a densely populated urban area, the landfill's environmental significance includes managing methane emissions through gas collection systems and protecting groundwater through liner and leachate control systems. Its proximity to residential areas necessitates careful traffic management and odor control to minimize community impact.

The landfill is situated in the San Gabriel Valley, a region with a Mediterranean climate and significant urban development. Key environmental considerations include methane leakage from landfill gas, which contributes to greenhouse gas emissions, and leachate management to prevent groundwater contamination. The facility's proximity to communities in Monrovia and surrounding areas requires robust odor control and traffic management to mitigate local impacts.
