International Isotopes Announces Nuclear Regulatory Commission Approval of the Final Environmental Impact Statement for the Planned Depleted Uranium De-Conversion and Fluorine Extraction Processing Facility

IDAHO FALLS, Idaho, Sept. 4, 2012 /PRNewswire/ -- International Isotopes Inc. (OTC Bulletin Board: INIS) is pleased to announce the U.S. Nuclear Regulatory Commission (NRC) has completed its review, approval, and publication of the final Environmental Impact Statement (EIS) for the Company's planned depleted uranium de-conversion and fluorine extraction processing facility. The final EIS is published as U.S. NRC Regulation (NUREG-2113) and is available on the NRC website. The NRC and Environmental Protection Agency (EPA) have published notices of the final EIS in the Federal Register.

The Company originally submitted its license application to the NRC in December 2009, and the NRC has been reviewing that application since that time. The Company previously announced on May 31, 2012 the NRC had completed its approval and publication of the Safety Evaluation Report (SER) for the planned facility. The NRC approval and the EPA's publication of the final EIS represents approval of the last documents required for the NRC construction and operating license to be issued. The final EIS is required to be posted in the Federal Register for 30 days prior to the NRC's issuance of the license. Based upon the final EIS publication date the Company anticipates that the NRC will be issuing the license to the Company on or about the first week of October 2012.

Steve T. Laflin, President and CEO of the INIS commented, "The NRC approval of the final EIS is the last major milestone in the Company's nearly three year effort to license and construct the first ever "green" depleted uranium de-conversion and fluorine extraction processing facility in the U.S. The conclusion of the final EIS that the facility will have a small environmental impact is indicative of the efforts the Company has made to design the plant using state of the art engineering controls and place a high priority upon environmental considerations intended to reduce the footprint and environmental influence of the facility on the south east New Mexico landscape. I would once again like to recognize the NRC staff for their excellent coordination and communication with the Company throughout the license review process and their efforts to complete the license review process in as timely a manner as possible."
