Biennial Hazardous Waste Reporting


Biennial Hazardous Waste Reporting

Hazardous waste generators in California are required by federal and state regulations to submit a Biennial Hazardous Waste Report detailing waste streams and quantities handled at their facility. This comprehensive report must be submitted to Environmental Protection Agency (EPA) every two years.

Meeting biennial reporting obligations can be an arduous process (the EPA estimates an average of 17 hours is needed for businesses to accurately prepare these complex hazardous waste reports), but it doesn’t have to be. Let CDMS Consulting’s experienced team prepare and submit your Biennial Hazardous Waste Reports for you. With CDMS, you can have your hazardous waste biennial reports prepared for less cost than it would take your team to complete them in-house, saving your staff time and ensuring regulatory compliance.
