EPA Hazardous Waste Biennial Reports from 1999

U.S. Environmental Protection Agency collects biennial reports on hazardous waste generation and management under the Resource Conservation and Recovery Act. Data is compiled by authorized states and EPA regions, with public files available from 1999 to the present. The reports support regulatory activities and provide statistics on waste trends.

Use Cases

• Analyze hazardous waste generation trends over time using biennial report data from states and EPA regions
• Study waste management and final disposition patterns reported by RCRA handlers like Large Quantity Generators (LQG) and Treatment, Storage, and Disposal Facilities (TSDF)
• Map the geographic distribution of hazardous waste activities using State and United States location tags from the reports

Strengths

• Data collection spans over two decades, with files available from 1999 to the present
• Reports are compiled by authorized state agencies and EPA regions, providing regulatory oversight
• Covers multiple waste generator types, including Large Quantity Generators (LQG) and Small Quantity Generators (SQG)

Limitations

• Update frequency is biennial (every other year), limiting timeliness for annual analysis
• Historical data prior to 1999 is not readily downloadable and must be ordered on CD
• Data is reported by states and regions without EPA modification, potentially introducing inconsistencies
