Hazardous Waste Identification Process Rules

Revision of Wastewater Treatment Exemptions for Hazardous Waste Mixtures (Headworks Rule)
This rule allows generators to directly measure solvent chemical levels at the headworks of the wastewater treatment system to determine whether the wastewater mixture is exempt from the definition of hazardous waste.

Definition of Solid Waste; Response to Court Order Vacating Regulatory Provisions
This action deletes regulatory language that classified mineral processing characteristic sludges and byproducts being reclaimed as solid wastes under RCRA's hazardous waste management regulations, and codifies the decision that the Toxicity Characteristic Leaching Procedure (TCLP) may not be used for determining whether manufactured gas plant (MGP) waste is hazardous under RCRA.

Hazardous Waste Identification Rule (HWIR: Waste)
EPA proposed several significant changes to the hazardous waste identification process in its HWIR: Waste proposed rule. Some of the proposals have been finalized, while others remain under review.

Hazardous Waste Identification Rule for Contaminated Media (HWIR: Media)
EPA issued a final rule governing the management of hazardous waste-contaminated media from site remediations that are treated, stored, or disposed during cleanup actions. This final rule withdraws many of EPA's proposed options for excluding contaminated media and other remediation wastes from Subtitle C.

The Off-Site Rule
The Off-Site Rule (OSR) establishes the criteria and procedures for determining whether facilities are acceptable for the receipt of CERCLA wastes from response actions authorized or funded under CERCLA. The OSR establishes compliance criteria and release criteria, and establishes a process for determining whether facilities are acceptable based on those criteria.
