Final HWIR-Media Rule Fact Sheet

Fact Sheet

November 1998

What is the HWIR-media rule?

The HWIR-media rule is a final regulation that is part of President Clinton's March 1994 environmental regulatory reform initiative. The rule sets new requirements under the
Resource Conservation and Recovery Act (RCRA) for hazardous remediation wastes that are treated, stored, or disposed of during cleanup actions. Specifically, the rule:

What is the background for this rule?

On April 29, 1996, EPA proposed new regulatory provisions entitled "Requirements for Management of Hazardous Contaminated Media" (61 FR 18780). That proposal, also known as the "Hazardous Waste Identification Rule for Contaminated Media" (or HWIR-Media), included a broad range of potential reforms. Among those reforms, EPA proposed options for excluding contaminated media and other remediation wastes
from Subtitle C. For the reasons described in the following paragraph, EPA is not finalizing those broad reforms in the HWIR-media final rule, but instead is finalizing only the reforms listed above. EPA has already finalized the 1996 proposed provisions for standards for hazardous soils. These provisions were in the May 26, 1998, Phase IV final rule (63 FR 28556).

Although EPA conducted a lengthy outreach process before developing the HWIR-Media proposal and tried to balance the concerns and interests of various stakeholder groups, it is clear after reviewing public comment on the proposal that stakeholders have fundamental disagreements on many remediation waste management issues. EPA has concluded that pursuing comprehensive regulatory reform would be time- and resource-intensive and would most likely result in a rule that would provoke additional years of litigation and associated uncertainty. This uncertainty would be detrimental to the program and would have a negative effect on ongoing and future cleanups. Therefore, EPA is withdrawing the proposed options for broad reforms – such as those that exempted remediation wastes from Subtitle C – and is, instead, finalizing only those reforms listed.

One of the 1996 HWIR-Media options proposed was the withdrawal of the Corrective Action Management Unit (CAMU) rule because its flexibility would be replaced with the
proposed broad reforms. However, because EPA is not finalizing those broad reforms, the CAMU rule will be retained as it currently exists in 40 CFR Section 264.552

Does the HWIR-media rule apply new mandatory requirements?

No. Adoption of the requirements of this rule is optional for authorized state RCRA programs because these requirements are less stringent then the existing requirements. Even after these new regulations are adopted and authorized for state programs, facilities may choose not to take advantage of them and may choose, instead, to comply with the traditional requirements for hazardous waste management.

Is EPA changing policies that currently provide flexibility for remediation waste management?

No. Existing areas of flexibility for the management of hazardous remediation waste such as the "contained-in" and "area of contamination" policies and site-specific land disposal restrictions treatability variances continue to be available.

What impacts does EPA expect the HWIR-media rule to have?

EPA anticipates that the HWIR-media rule will:
