Sunnyside Landfill is an operational solid waste facility located in Lassen County, California, United States. As a landfill, it plays a key role in managing municipal solid waste for the surrounding area. The facility operates under the jurisdiction of the US EPA and California state regulations, which govern landfill design, operation, and closure.

Proper landfill management is critical for minimizing methane emissions and protecting groundwater, especially in areas with sensitive ecosystems.

Landfills in California must manage landfill gas, which is primarily methane, a potent greenhouse gas. Gas collection systems are typically required to reduce emissions. Leachate management is also critical to prevent groundwater contamination, especially in areas with shallow water tables or nearby surface waters. The facility's location in Lassen County, a rural area with low population density, may reduce community proximity concerns but still requires careful environmental monitoring.
