After Action Report/Improvement Plan South Texas Project EXECUTIVE

SUMMARY

On October 27, 2010, a biennial Radiological Emergency Preparedness (REP) exercise, which included a relocation, return, reentry demonstration, was conducted in the plume exposure pathway emergency planning zone (EPZ) around the South Texas Project (STP) located near Wadsworth, Matagorda County, Texas. The U.S. Department of Homeland Security/Federal Emergency Management Agency (DHS-FEMA), Region VI, evaluated the exercise. The purpose was to assess the level of preparedness of state and local responders to react to a simulated radiological emergency at STP. This exercise was held in accordance with FEMA's policies and guidance concerning the implementation of state and local radiological emergency preparedness plans and procedures.

The previous exercise at this site was conducted on July 23, 2008. The qualifying emergency preparedness exercise to satisfy FEMA rule 44 Code of Federal Regulations 350 requirements for U.S. Nuclear Regulatory Commission licensing to operate the facility was conducted on April 8, 1987. There have been thirteen evaluated exercises, including the exercise on October27, 2008, plus several drills conducted since 1987.

FEMA, Region VI wishes to acknowledge the efforts of the many individuals in the State of Texas, Matagorda County, Bay City, the City of Palacios and surrounding jurisdictions who participated in this exercise. Protecting the public health and safety is the full-time job of some of the exercise participants and an additional assigned responsibility for others. Still others have willingly sought this responsibility by volunteering to provide vital emergency services to their communities. Cooperation and teamwork of all the participants was evident during this exercise.

This report contains the final written evaluation of the biennial exercise. All state and local organizations, except where noted in this report, demonstrated knowledge of their emergency response plans and procedures and adequately implemented them. There were no Deficiencies, two Areas Requiring Corrective Action (ARCA) corrected during the exercise and no Plan Issues identified during this exercise.

ISSUE NO.: 60-10-4a3-A-01 CRITERION: Ambient radiation measurements are made and recorded at appropriate locations, and radioiodine and particulate samples are collected. Teams must move to an appropriate low background location to determine whether any significant (as specified in the plan and/or procedures) amount of radioactivity has been collected on the sampling media. (NUREG-0654, I.8., 9., 11)

CONDITION: Field Monitoring Team lacked necessary sampling filter cartridge to carry out sampling mission.

POSSIBLE CAUSE: Assumed that unknown third party removed filter that had been prepared the previous day by Field Monitoring Team member in anticipation of the exercise. The sample filter holder had been prepared the previous day and packed back in the transport container. Someone had removed the charcoal sample filter without the Team member's knowledge before the Team deployed into the EPZ.

REFERENCE:

Criterion 4.a.3: Ambient radiation measurements are made and recorded at appropriate locations, and radioiodine and particulate samples are collected.

12

Unclassified Radiological Emergency Preparedness Program (REP)

After Action Report/Improvement Plan South Texas Project EFFECT: Contrary to the requirement in Criterion 4.a.3, no sample was collected because the necessary sampling filter media was not in the sample holder while the sample pump was operating.

CORRECTIVE ACTION DEMONSTRATED: Another sample filter cartridge was obtained from Field Monitoring Team 2 and Team 1 returned to the sample location to repeat the sampling procedure. The sample preparation procedure was simulated in an acceptable manner.

Teams must move to an appropriate low background location to determine whether any significant (as specified in the plan and/or procedures) amount of radioactivity has been collected on the sampling media. (NUREG-0654, I.8., 9., 11)

CONDITION: Department of Health Services - Radiation Control Program Field Monitoring Team Two handled iodine air sample media in a manner that could cross-contaminate the sample (the iodine cartridge was removed from the air sample head with a potentially contaminated gloved hand).

POSSIBLE CAUSE: Texas Emergency Management Procedure 10.1, Monitoring and Sampling Airborne Gamma Releases does not include detailed steps that aim to 13

Unclassified Radiological Emergency Preparedness Program (REP)

After Action Report/Improvement Plan South Texas Project minimize the probability of the sample being cross contaminated during packaging.

Additionally, field monitoring team members indicated that they had not been trained on contamination control techniques while removing the iodine cartridge from the air sample head.

REFERENCE:

NUREG 0654 I.8-9; Texas Emergency Management Procedure 10.1, Monitoring and Sampling Airborne Gamma Releases, Air Sampling EFFECT: If the iodine sample were cross contaminated, the resulting analysis would be imprecise and higher than actual. This analysis is used to make or confirm dose projections and protective action decisions. A cross contaminated sample could lead to more of the general population being evacuated than is warranted.

CORRECTIVE ACTION DEMONSTRATED: Training was provided to field monitoring team members on sample handling to prevent cross contamination of sample media. Consideration should be given to revising the air sampling procedure to include more detail or a note of explanation regarding contamination control.

A time out was called during the initial iodine sample packing. The exercise controller worked with participants and discussed contamination control and sample packaging. The field monitoring team discussed two methods to handle the sample to minimize the potential to cross contaminate the sample (wear and remove an extra pair of gloves, or have the second person hold open the plastic bag and drop the iodine cartridge into the bag without touching the cartridge). The field monitoring team then demonstrated appropriate sample handling/packaging by removing the sample cartridge without touching the filter media.

After Action Report/Improvement Plan South Texas Project SECTION 4: CONCLUSION Based on the results of the exercise, the offsite radiological emergency response plans and preparedness for the State of Texas and the affected local jurisdiction are deemed adequate to provide reasonable assurance that appropriate measures can be taken to protect the health and safety of the public in the event of a radiological emergency. Therefore, 44 CFR Part 350 approval of the offsite radiological emergency response plans and preparedness for the State of Texas site-specific to the South Texas Project will remain in effect.

16

Unclassified Radiological Emergency Preparedness Program (REP)

After Action Report/Improvement Plan South Texas Project APPENDIX A: BEST PRACTICES

1. The Department of State Health Services at the Emergency Operations Facility Summary: The Department of State Health Services (DSHS) at the Emergency Operations Facility (EOF) showed excellent coordination & a great partnership with utility counterparts that allowed DSHS personnel to quickly identify and remedy any possible inconsistencies, such as the KI authorization for special needs population. Accident assessment team members had a good peer checking system in place to assure no mistakes were made and proper recommendations were made.

==

Description:==

After receiving the dose projections from accident assessment, the DSHS Incident Commander made her protective action recommendations and presented them to both DSHS accident assessment team members to peer-check them and to the South Texas Project's (STP) accident assessment team to coordinate a concurrence before presenting these recommendations to the County Judge. This was done in accordance with procedure. DSHS REM Procedure 1-Accident Assessment: Plume Exposure Pathway The peer checking system that was in place successfully assured that no mistakes were made and proper recommendations were given. This peer checking system was demonstrated during a FEMA evaluated exercise and will continue to be practiced in future training and exercises.

2. The Texas Department of Public Safety (DPS) Disaster District Sub-2C located in Pierce, Texas Summary: DDC Pierce office was well run. Participants were well trained and effectively used Web-EOC, a newer technology, to their benefit.

==

Description:==

Web EOC is an information sharing web-based program that allowed the DDC, County EOC and State Operations Center to share significant events such as press releases, levels of emergency, and protective action decisions on an accessible website. It also electronically maintained emergency responder logs and made the local logs accessible to the State Operations Center.

Because Web EOC is a newer technology, a procedure has not been put into place as of yet.

17

Unclassified Radiological Emergency Preparedness Program (REP)

After Action Report/Improvement Plan South Texas Project WebEOC successfully provided timely and accurate information to all levels of government who were involved in emergency response during this exercise. WebEOC is currently used in state-wide emergency operations, and will continue to be used in future REP training and exercises.

3. Joint Information Center Summary: JIC - The STP JIC Media Liaison team was innovative in taking members of the mock media on a tour of a DSHS Mobile Lab and simulating to the media a walk-through of a reception center. Media Liaison team members provided handheld microphones to mock media, ensuring that all questions and answers were heard during press conferences. The Media and Public Inquiry team used both phones and an online program to answer public and media inquiries. The online program, PIER, was also utilized for team members to log calls and answers. The Media and Public Inquiry team also used a translation firm to answer phone questions posed in Russian, Japanese and Vietnamese. All spokespersons were polished, informative and credible during press conferences.

==

Description:==

While not graded, the Mock Media did a superb job of pushing questions and follow-up questions to the OROs. The Mock Media also provided stories via VHS, digital radio and print to the Media Monitor after every press conference. This practice is unusual but fruitful as it exercises Media Monitor teams who typically just show the capability of monitoring by turning on TVs, radios and computers.

The Mock Media provided exercise players with challenging questions and follow-up questions that enabled the OROs to exercise their public speaking capability. Although it was not graded, PIER proved to be a web-based tool that successfully allowed the utility to provide information to the public in a timely fashion.

By injecting mock stories via VHS, digital radio and print throughout the exercise, it enabled better training for the JIC media team and provided more realism to the evaluated exercise.

4. Strengths Summary: KMKS staff extremely proactive with verification and authentication of all communication from Matagorda County Emergency Operations Center (MCEOC).

Accomplished communication checks for all equipment and paid attention to detail, particularly 18

Unclassified Radiological Emergency Preparedness Program (REP)

After Action Report/Improvement Plan South Texas Project regarding constant fax paper tray checks. These were impressive as these details are often overlooked by busy staff. Checking dial tones and constantphone check-ins with MCEOC was helpful in establishing a successful operation. Enthusiasm for Drill was evident and live broadcast of a test emergency was done on air and seamlessly with no error. Overall great cohesion of KMKS team helped facilitate the disemination of information and allowed KMKS staff to coordinate among each other and stay focused.
