Landfills in Southern California face challenges related to methane emissions and groundwater protection. Simi Valley LF likely employs landfill gas collection systems to mitigate methane leakage, a potent greenhouse gas. Proximity to residential areas in Simi Valley requires careful management of odor, traffic, and litter. Leachate management is critical given the region's semi-arid climate and potential for groundwater contamination. The facility's long-term operation until 2062 underscores the need for ongoing environmental monitoring and compliance with evolving regulations.
