Lost Creek ISR, LLC

The U.S. Nuclear Regulatory Commission (NRC) is issuing a temporary exemption from certain NRC financial assurance requirements to Lost Creek ISR, LLC (Lost Creek), in response to its annual financial assurance update for its Lost Creek In-Situ Recovery (ISR) project. Issuance of this temporary exemption will not remove the requirement for Lost Creek to provide adequate financial assurance through an approved mechanism, but will allow the NRC staff to further evaluate whether the State of Wyoming's separate account provision for financial assurance instruments it holds is consistent with the NRC's requirement for a standby trust agreement.
