FIELDSTONE ONTARIO RESIDENTIAL PLAN - Landfill in Ontario, California, USA

FIELDSTONE ONTARIO RESIDENTIAL PLAN is a landfill facility located in Ontario, California, within San Bernardino County. It is currently operational and serves the residential solid waste management needs of the region. As a landfill, it plays a key role in the local waste disposal infrastructure. The facility operates under the regulatory framework of the United States Environmental Protection Agency (EPA), specifically RCRA Subtitle D for municipal solid waste landfills and Clean Air Act (CAA) rules for landfill gas emissions. These regulations mandate landfill gas collection and control systems to reduce methane emissions, as well as leachate management to protect groundwater. The NAICS code 562212 indicates it is classified as a Solid Waste Landfill. Located in Southern California, the landfill serves a densely populated urban area with significant waste generation. Its environmental significance lies in managing residential waste while mitigating potential impacts such as methane leakage, groundwater contamination, and community proximity. Proper operation under federal and state regulations is essential for minimizing these risks.

The landfill is situated in Ontario, California, a region with a semi-arid climate and proximity to groundwater resources. Key environmental concerns for this facility include landfill gas generation (primarily methane) and leachate production, which require robust collection and treatment systems. The site's location near residential areas and major highways (Pomona Freeway) also raises considerations for traffic, odor, and community impact. Regulatory compliance with EPA's landfill gas rules and RCRA Subtitle D is critical to mitigate these risks.
