National Environmental Policy Act (NEPA)

Review Air Quality

  • Evaluate the environmental effects of the facility operating Land use for another 40 years Noise and Aesthetics
  • Document results in an Ecology Environmental Assessment (EA)

Socioeconomics

  • Re-open the NEPA review due Transportation to leaks Water Quality and Use - Will issue draft EA for public review and comment 9

NEPA Review 10

Environmental Justice (EJ)

  • Analyze for disproportionately high and adverse human health and environmental effects on low-income and minority populations
  • NRC has a Policy Statement that provides guidance for performing EJ analyses
  • Previous EAs did not include EJ analysis because there were no significant impacts
  • Decision to conduct EJ analysis will follow process outlined in Policy Statement 11

Oversight

  • Verify Westinghouse is meeting the regulatory requirements as described in their license
  • Assess the overall safety performance of the facility by reviewing trends
  • Issue violations if regulatory requirements are not met Level of violation (severity) ranges from I to IV 12

2018 Leak - Event

  • June 2018: Leak occurred at Spiking Station #2 Pipe coupling leak Hydrofluoric acid and uranyl nitrate No workers injured Damage to liner and concrete floor Small Crack in Chemicals seeped into the soil Concrete Under the Liner
  • July 2018: NRC and SC 48 Department of Health and 67 Environmental Control 19 (DHEC) notified 13

2018 Leak - Response

  • NRC completed an inspection Sept 18-21 and issued a Level IV violation

- Westinghouse must respond to the violation within 30-days

  • Westinghouse completed an apparent cause evaluation, implemented compensatory measures, and continues to take corrective actions
  • Westinghouse is still determining the extent of the leak into the subsurface and coordinating with DHEC for further actions

- Results of the sampling will be evaluated in the license renewal review 14

2018 Leak - Next Steps

  • DHEC approved Westinghouse Soil Sampling Plan

- Phase I (completed): Conduct 12 borings and collect samples from the area under the dike to a depth of up to 5 feet and analyze results for contamination levels

- Phase II (completed): Conduct additional borings and collect samples down to approximately 12 feet

- Phase III (if necessary): Obtain ground water samples below the dike for analysis

  • Compensatory measures put in place for operating Hydrogen Fluoride Spiking Station #1:

- Hourly piping leak checks

- Protective mats placed on liner if an operator needs to walk on liner

- Following any entry to diked area, the liner integrity check will be completed

- Liner integrity check frequency changed from annual to quarterly 15

2008 and 2011 Leaks

  • Westinghouse found leaks in 2008 and 2011 in an underground piping system that goes from the facility to the wastewater treatment plant
  • Westinghouse implemented corrective actions

- Re-routed acidic and/or caustic solutions

- Portions of the line inside the building were re-routed above ground

- Piping was re-lined 16

2008 and 2011 Leak - Next Steps

  • January 2018: Westinghouse initiated effort to further characterize and determine extent of leaks Drilled temporary wells to obtain water samples to determine extent of contamination, if any Efforts are ongoing Results will be evaluated in the license renewal review 17

Decommissioning

  • Westinghouse is required to decommission the site once operations have ceased and clean up to allow for unrestricted use
  • NRCs Decommissioning Planning Rule 18

Closing Remarks

- Draft EA will be published for public comment

- Safety Evaluation Report will document the conclusions of the safety review

  • Oversight and Inspection

- Completed the inspection and issued a violation

- Westinghouse must respond to the violation

- Westinghouse continues to investigate the leaks 19
