Uranium Program Updates and Recent Rule Changes Gary L. Smith, Ph.D., Manager Uranium Section Radioactive Materials Division Texas Commission on Environmental Quality May 7, 2014
Texas In Situ Uranium Facilities • RGR Panna Maria/Hobson R06063, licensed in 2012, pre-construction status. • Signal Equities Brevard R06065, licensed in 2011, pre-construction status and recent expansion amendment. • UEC Goliad R06064, licensed in 2011, pre-construction status.
Texas In Situ Uranium Facilities • STMV Palangana R06062, licensed 2010, producing loaded resins, expanding into new production areas. • Mesteña Alta Mesa R05360, licensed 2004, completed expansion amendment, on standby. • Uranium One R03024, license terminated June 2013 and released for unrestricted use.
Texas In Situ Uranium Facilities • STMV Hobson/Mt Lucas R03626, licensed as South Texas Mining Venture in 2010, actively processing loaded resins, Tex-1 was released, June 2013, Mt Lucas to be released for unrestricted use, soon. • URI Kingsville Dome/Rosita/Vasquez R03653, standby.
Texas Conventional Uranium Facilities • All conventional uranium sites are currently in closure. • ConocoPhillips Conquista R01634 – impoundment cap maintenance, soil decontamination, and groundwater issues.
Texas Conventional Uranium Facilities • ExxonMobil Ray Point R01431 – soil decontamination. • RGR Panna Maria R02402 – continuing to work on groundwater issues.
Other Texas Uranium Facilities • IEC Lamprecht/Zamzow L02538 - license for the Lamprecht and Zamzow sub-sites was revoked in 2003. TCEQ and other parties still working on reclamation solutions with a possibility of partial release of small areas that meet regulatory criteria.
Texas Soil Rule Change • Response to a Petition for Rule Change to §336.1115(e) pertaining to soil standards for decontamination. • Radium-226 soil standard limits remain at 5/15. • Texas uranium soil contamination limits were dropped. • The radium soil limit is coupled with the Radium Benchmark Dose Limit Method.
Update of Federal Regulations • 40 CFR Part 192 issued under the Uranium Mill Tailings Radiation Control Act (UMTRCA) - establishes health, safety, and environmental protection standards for uranium and thorium mill tailings. • 40 CFR Part 61, Subpart W, issued under authority of the Clean Air Act - provides standards for radon emissions from active uranium mill tailings impoundments.
EPA’s Focus for 40 CFR 192 will be Groundwater EPA published “Considerations Related to Post-Closure Monitoring of Uranium in-situ leach/in-situ recovery (ISL/ISR) Sites”, 2012.
EPA’s Progress on 40 CFR 192 As of Spring 2014, EPA hopes to send a proposal for 40 CFR 192 to the Office of Management & Budget for interagency review, and have a proposed rule out later, this year.
EPA’s Progress on 40 CFR 61, Subpart W • The EPA completed its revisions of 40 CFR Part 61 Subpart W and sent the proposal to the Office of Management and Budget for review, last summer. • This regulation applies to the radon emission standard for operating uranium mill tailings facilities, i.e., the Rn-222 flux standard of 20 pCi/m2/sec.
EPA’s Progress on 40 CFR 61, Subpart W • The revised rule has not yet been made public, but it is believed that ponds at in situ leach facilities will be included. • The rule package is an internal document at this stage, but is close to being published in the Federal Register.
NRC Projects • Revisions to NUREG-1569, “Standard Review Plan for In Situ Leach Uranium Extraction License Applications”, deferred until EPA completes their revision of 40 CFR 192. • An NRC working group has completed an update of "Information Notice 99-03" with new information on yellowcake packaging.
NRC Projects • Draft NUREG-2126, “Standard Review Plan for Conventional Uranium Mill and Heap Leach Facilities.” This should be available for review this summer. • Draft Regulatory Guide 4.14, “Radiological Effluent and Environmental Monitoring at Uranium Mills.” This should be ready for review this summer.
