WIPP Oversight
Waste Management: 

2006 WIPP Recertification Decision

WIPP

On March 29, 2006, EPA officially recertified that the U.S. Department of Energy’s Waste Isolation Pilot Plant (WIPP) continues to comply with the waste disposal regulations at 40 CFR Part 191, Subparts B and C and WIPP Compliance Criteria at 40 CFR Part 194.

In the WIPP Land Withdrawal Act, Congress required EPA to “recertify” the facility every five years following the initial receipt of transuranic (TRU) waste until the end of its operational activities. WIPP first received TRU waste on March 26, 1999, and this action represents the first of EPA’s periodic evaluations of the facility's continued compliance.

How does recertification affect the operation of WIPP?

Recertification is a process that evaluates changes at WIPP, to determine whether the facility continues to meet all the requirements of EPA’s disposal regulations. The recertification process helps ensure WIPP's continued compliance based on the most accurate, up-to-date information available. Recertification does not mean that the decision to open WIPP is being reconsidered.
