How long am I required to keep hazardous waste manifests for?

You must retain hazardous waste manifests for three years. In addition, the following records must also be retained for that timeframe:

• All notices and documentation associated with Land Disposal Restrictions
• Biennial Reports
• Exception Reports
• Any test results, waste analyzes, or similar information related to the waste shipped off-site
• Your inspection schedule and reports. (Specific inspection requirements are found in 40 CFR 265.15.)
