Low Level Radioactive Waste Management and Disposal September 18, - PowerPoint PPT Presentation

Low Level Radioactive Waste Management and Disposal September 18, 2014 Charles Maguire, Director, Radioactive Materials Division Texas Commission on Environmental Quality 1

Texas Low level Radioactive Waste Compact Federal Low-Level Waste Policy Act passed by U.S. Congress in 1980, amended in 1985, authorized states to form Compacts 2

CONTINUED Texas and Vermont have established the Texas Compact Vermont has paid state of Texas $25 million for waste disposal guarantee 3

Community Suppo rt TCEQ has worked with WCS to build the trust and support of the Andrews County community In 2010 Andrews County issued a $75.0 million general obligation bond to the company to finance construction of the facilities 4

CONTINUED Waste Control Specialists supports over 160 full-time jobs in Andrews County and to date has created $4.0 million in county revenue and $16.0 million in state revenue

Radioactive Waste Disposal Storage and Processing License Low-Level and Mixed Low-Level Radioactive Waste Disposal License issued ─ September 2009 Compact – First Disposal in April 2012 and Federal – First Disposal in June 2013 7

Financial Assurance Financial Assurance is reviewed • annually and adjusted for inflation and current site requirements Current requirements are: •  Unplanned closure: $33.30 million  Post closure: $9.22 million  Institutional control: $22.79 million  Corrective action: $20 million 8

Dose Modeling for Intruder Resident • Exposure Pathways : – Gas inhalation – Dust inhalation – Plant ingestion – External irradiation – Drinking water evaluated (but not a viable exposure pathway due to limited yield in 225’zone) • Intruder Scenarios: – Rancher Peak dose less than 20 mrem/year at 1 million – Oil Well Driller years. Limit is 500 mrem/year. – On-site Resident 10
