RCRA

Explore how listed waste history affects mixtures and treatment residues, why characteristics differ, and why testing alone does not remove a listing.

Learn how state adoption, EPA authorization, effective dates, permits, and official sources fit together when researching hazardous waste requirements.

Understand the difference between total concentrations and TCLP extracts, screening limitations, and why a low TCLP result does not resolve every waste determination.

Understand monthly generation counts, conditional exclusions, acute waste thresholds, and the separate role of on-site accumulation.

Separate the federal acute hazardous-waste thresholds used for monthly category, onsite accumulation, and satellite areas.

Understand the federal SQG 180-day accumulation period, the 270-day distance provision, and temporary-extension controls.

Apply the federal three-consecutive-calendar-day workflow after a satellite accumulation area exceeds its quantity limit.

Learn who needs an EPA hazardous-waste identification number, how site-based numbers work, and which changes require an update.

Identify the events that should trigger review of a hazardous-waste determination and build a controlled reevaluation record.

Build a federal-baseline documentation file for the RCRA wastewater treatment unit exemption, unit boundaries, Clean Water Act status, residues, and changes.
