Low Level Radioactive Waste Management and Disposal

Charles Maguire, Director, Radioactive Materials Division Texas Commission on Environmental Quality September 18, 2014

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

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

Community Support

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

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

• 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 – Oil Well Driller – On-site Resident

Peak dose less than 20 mrem/year at 1 million

• years. Limit is 500 mrem/year.
