Hazardous Waste Generators (HWG)

If your facility possesses materials that constitute being labeled "hazardous waste," then your facility is considered a Hazardous Waste Generator. Materials that are toxic, corrosive, reactive, and ignitable are considered to be hazardous materials (22 CCR § 66262.11). To ensure that each facility is doing its job to protect local residents and the environment, Plumas County Environmental Health inspects, educates, investigates complaints, and enforces the laws and regulations about hazardous waste.

Generator Requirements Guide


To ensure that HMBP and HWG requirements are met and that the facility complies with State and Federal law, the Environmental Health Department conducts routine inspections at all facilities that are HWG. These inspections also assist in identifying safety hazards that could lead to an accidental spill or release of hazardous materials and allow the Specialist to work with facility owners on how to avoid hazardous release problems.
