The Resource Conservation and Recovery Act (RCRA), enacted in 1976, established the framework for the proper management of hazardous solid waste in the United States. Administered by the U.S. Environmental Protection Agency (EPA), RCRA’s primary goals are to protect human health and the environment, reduce waste, and encourage resource conservation and recovery. Under RCRA Subtitle C, hazardous waste regulations govern the generation, transportation, treatment, storage, and disposal of hazardous wastes from “cradle to grave.”

A material is considered a hazardous waste if it is specifically listed in the federal regulations (40 CFR Part 261 Subpart D) or exhibits one or more of four hazardous characteristics: ignitability, corrosivity, reactivity, or toxicity. Proper waste characterization is critical, as it determines how a waste must be managed and disposed of. Failure to accurately identify a waste can lead to noncompliance, potential environmental harm, and significant regulatory penalties.

Facilities that produce hazardous waste are classified into one of three generator categories based on the amount of hazardous waste generated per month:

• Very Small Quantity Generators (VSQGs) – Generate less than 100 kilograms per month
• Small Quantity Generators (SQGs) – Generate between 100 and 1,000 kilograms per month
• Large Quantity Generators (LQGs) – Generate 1,000 kilograms or more per month

A facility’s generator category will dictate which RCRA requirements it must comply with, including but not limited to waste accumulation time limits, personnel training, contingency planning, and biennial reporting.

Biennial Hazardous Waste Reporting

LQGs are required to submit a Hazardous Waste Report to the EPA or authorized state agency at least every two years. This ‘Biennial Report’ provides a comprehensive summary of hazardous waste generation and management activities for the reporting year. The report helps the EPA track waste trends, assess compliance, and evaluate the effectiveness of waste reduction initiatives.

The Biennial Report typically includes:

• Site identification information
• Quantities and types of hazardous wastes generated
• Details on how the wastes were managed on-site or shipped off-site
• Information on treatment, storage, or disposal facilities (TSDFs) receiving the waste

Biennial reports are due by March 1 of each even-numbered year, covering activities from the previous odd-numbered year. Generators should maintain accurate records throughout the reporting period to ensure complete and timely submissions.

While the EPA requires LQGs to submit a Biennial Hazardous Waste Report every two years under federal RCRA standards, individual states authorized to manage their own hazardous waste programs may impose additional or more frequent reporting requirements. These state-level variations reflect differences in oversight, data tracking, and environmental policy priorities. For example, South Carolina requires generators to submit quarterly hazardous waste reports, while Texas mandates an annual waste summary report. Other states follow the federal biennial schedule but may require supplemental state forms or electronic submissions through state-specific systems. Generators should always verify their state’s specific requirements to ensure compliance with both federal and state hazardous waste reporting obligations. Keeping up to date with reporting requirements helps organizations remain in compliance and supports the EPA’s mission to ensure safe and responsible waste management nationwide.
