=SUMMARY OF FINDINGS=
IR 05000336/2007-004, 05000423/2007-004; 07/01/2007 - 09/30/2007; Millstone PowerStation, Unit 2 and Unit 3; Post-Maintenance Testing.The report covered a 3-month period of inspection by resident inspectors and announcedinspections by regional inspectors. One Green finding was identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.A.
 
===NRC-Identified and Self-Revealing Findings===
 
===Cornerstone: Initiating Events===
: '''Green.'''
A self-revealing finding was identified for Dominion's failure to implementprocedure OP 3330B, "Turbine Plant Component Cooling Water" during restoration of the "B" turbine plant component cooling water (TPCCW) heat exchanger on August 28, 2007. Specifically, following maintenance that left the heat exchanger shell in a partially drained condition, Dominion did not fill and vent the heat exchanger in accordance with OP 3330B. This resulted in two of the three TPCCW pumps receiving an automatic trip signal on low suction pressure. Loss of the remaining TPCCW pump would have required the operators to manually trip the reactor within three minutes per plant procedures. Dominion entered this issue into their corrective action program as CR-07-09057. Corrective actions included revising OP 3330B to require the fill and vent section be used following maintenance to ensure the TPCCW side of the heat exchanger is completely full of water, and revising the work planning procedure to request operations work planning provide restoration packages for all applicable work orders. This finding is more than minor because it was associated with the human performanceattribute of the Initiating Events Cornerstone and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Dominion's failure to implement the fill and vent procedure, when required by heat exchanger conditions, could potentially have led to the loss of all TPCCW pumps and required operators to manually trip the reactor. This finding was determined to be of very low safety significance (Green) by performing a Phase 1 evaluation in accordance with NRC IMC 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. The finding has a cross-cutting aspect in the area of Human Performance, work practices component, because Dominion did not implement proper procedures for the restoration of the "B" TPCCW heat exchanger.

=====Introduction:=====
A self-revealing finding was identified for Dominion's failure to implementprocedure OP 3330B, "Turbine Plant Component Cooling Water," during restoration of the "B" TPCCW heat exchanger on August 28, 2007. Specifically, Dominion did not fill and vent the heat exchanger in accordance with OP 3330B following maintenance that left the heat exchanger shell in a partially drained condition. This resulted in two of the three TPCCW pumps receiving an automatic trip signal on low suction pressure. Plant 10Enclosureprocedures would have required the operators to manually trip the reactor within threeminutes had the third TPCCW pump tripped.Description:  On August 8, 2007, Dominion identified a tube leak originating from the "B"TPCCW heat exchanger. Dominion prepared a work package to identify and repair the source of the leak. On August 27, Dominion personnel began work on repairing the TPCCW heat exchanger. A leaking tube was identified near the bottom of the heat exchanger, and the leak rate was estimated to be approximately one half gallon per minute at that time. Dominion successfully completed the repairs to the heat exchanger on August 28. During restoration of the heat exchanger, when operators opened the "B" TPCCW heatexchanger discharge isolation valve, the "C" TPCCW pump immediately tripped on low suction pressure. The "B" TPCCW pump, which was in standby, also received an automatic trip signal on low suction pressure, preventing the pump from starting. The "A" pump, which was running, did not receive a trip signal and remained in operation.
 
Heat loads on the TPCCW system at full power require at least two pumps to be in service. The plant operated with only one TPCCW pump running for approximately five minutes, during which time lube oil temperatures increased and a generator bus duct cooling system high temperature alarm was received. Operators were able to restart the "B" TPCCW pump within five minutes, which provided sufficient cooling to the TPCCW system. Dominion's investigation determined that the TPCCW side of the heat exchanger hadbeen slowly draining through the failed tube since August 8, when the heat exchanger was first isolated. Restoring the "B" TPCCW heat exchanger while in a substantially drained condition resulted in two of the three TPCCW pumps receiving automatic trip signals on low suction pressure, and could have potentially also led to a trip signal beingsent to the only remaining TPCCW pump. The performance deficiency is that Dominion failed to implement procedure OP 3330B, Section 4.8, "Filling TPCCW Heat Exchanger(s)", when required by heat exchanger conditions following maintenance to repair a tube leak.Analysis:  As a result of not implementing OP 3330B, Section 4.8, "Filling TPCCW HeatExchanger(s)," Dominion restored the "B" TPCCW heat exchanger while in a substantially drained condition, which resulted in the "B" and "C" TPCCW pumps receiving automatic trip signals on low suction pressure. This finding is more than minor because it was associated with the human performance attribute of the Initiating Events Cornerstone and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Dominion's failure to implement the fill and vent procedure, when required by heat exchanger conditions, could potentially have led to the loss of all TPCCW pumps and required operators to manually trip the reactor. The inspectors conducted a Phase 1 screening of the finding in accordance with IMC0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations."  The finding was determined to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available.
 
11EnclosureThe performance deficiency has a cross-cutting aspect in the area of HumanPerformance, Work Practices, in that Dominion did not implement proper procedures for the restoration of the "B" TPCCW heat exchanger. [H.4(b)]Enforcement:  Enforcement action does not apply because the performance deficiencydid not involve a violation of regulatory requirements because the TPCCW system is not safety-related equipment. Dominion entered this issue into their corrective action program (CR-07-09057). Corrective actions include revising the work planning procedure to request Operations Work Planning provide restoration packages for all applicable work orders, and revising OP 3330B to require the fill and vent section be used following maintenance to ensure the TPCCW side of the heat exchanger is completely full of water. Because this finding does not include a violation of regulatoryrequirements and is of very low safety significance (Green), it is identified as FIN05000336/2007004-01, Failure to Perform Fill and Vent of TPCCW Heat ExchangerResulted in Loss of Two TPCCW Pumps.

==1R22 Surveillance Testing (71111.22)==
 
====a. Inspection Scope====
(Seven Samples)The inspectors reviewed surveillance activities to determine whether the testingadequately demonstrated equipment operational readiness and the ability to perform the intended safety-related function. The inspectors attended pre-job briefs, reviewed selected prerequisites and precautions to determine if they were met, and observed the tests to determine whether they were performed in accordance with the procedural steps. Additionally, the inspectors reviewed the applicable test acceptance criteria to evaluate consistency with associated design bases, licensing bases, and TS requirements and that the applicable acceptance criteria were satisfied. The inspectors also evaluated whether conditions adverse to quality were entered into the corrective action program for resolution. Documents reviewed during the inspection are listed in the Attachment. The following surveillance activities were evaluated:Unit 2*On July 19, 2007, "A" containment spray pump and check valve IST;*On July 27, 2007, "C" high pressure core spray check valve IST;

==1EP4 Emergency Action Level (EAL) and Emergency Plan Changes==
{{IP sample|IP=IP 71114.04}}
 
====a. Inspection Scope====
(One Sample)Since the last NRC inspection of this program area, the latest Emergency Plan Revisionwas implemented based on Dominion's determination, in accordance with 10 CFR 50.54(q), that the changes resulted in no decrease in effectiveness of the Plan, and that the revised Plan continued to meet the requirements of 10 CFR 50.47(b) and Appendix E to 10 CFR 50. The inspector conducted a sampling review of the Emergency Plan changes, and all changes to EALs, to evaluate for potential decreases in effectiveness of the Emergency Plan. However, this review was not documented in a Safety Evaluation Report and does not constitute formal NRC approval of the changes.
 
Therefore, these changes remain subject to future NRC inspection in their entirety.

====a. Inspection Scope====
(Nine samples)During the period September 24-28, 2007, the inspectors conducted the followingactivities to evaluate the operability and accuracy of radiation monitoring instrumentation, and the adequacy of the respiratory protection program, relative to maintaining and issuing self-contained breathing apparatus (SCBA). Implementation of these programs was reviewed against the criteria contained in 10 CFR 20, applicable industry standards, and Dominion's procedures. The inspectors reviewed the UFSAR to identify area radiation monitors that are installedin Millstone Units 2 and 3 for the protection of workers, and reviewed the calibration procedure and current calibration records for selected instrumentation, including the Unit 2 spent fuel area monitors (RM-8139/8142/8156/8157), the Unit 3 spent fuel pool area monitors (3RMS-RIY08/36) and the Unit 3 containment area monitors (RE-01/02/03). The inspector discussed with the Instrument and Control (I&C)supervisor the monitoring system health report and instrument reliability trends. The inspector reviewed the operating procedure and current source activities/dose ratecharacterizations for the Shepherd Model 89 instrument calibrators (Serial Nos. 9155 &
9068). The inspector observed a technician perform safety interlock testing on the calibrator prior to using it.
 
15EnclosureThe inspector reviewed the calibration records for selected survey instruments andcontamination monitors including the small article contamination monitors (SAM 9 & 11),personnel contamination monitors (ARGOS-4A/B), electronic dosimeters (SeimensMk2), and various portable survey instruments (FH40TC, RO-2A, RO-20).The inspector reviewed the relevant procedures and observed a technician performing acalibration validation on electronic dosimeters and calibrate portable radiation survey instruments (RO-2A & RO-20).The inspector observed a technician performing daily functional checks on a variety ofcontamination monitors and survey instruments located in Units 2 and 3 including SAC-4, SAM-11, ARGOS 4A/B, CM-11, RM-14, Ludlum 177, BC-4, and Teleprobes.
 
The inspector reviewed the procedure and quality control records associated with performing the instrument daily functional checks, including air sample counting equipment and gamma spectrometers.The inspector reviewed recent contamination sampling (10 CFR 61 data) results forUnits 2 and 3 to determine if the instrument calibration sources used were representative of the radioisotopes found in the plant source term.The inspector evaluated the adequacy of the respiratory protection program regardingthe maintenance and issuance of SCBA to emergency response personnel. Training and qualification records were reviewed for  licensed operators from each of the five operating shifts at each unit and for selected response personnel who would wear SCBAs in the event of an emergency. The inspector, with the assistance of Fire Protection technicians, physically inspectedthree SCBAs staged for use in each control room, two SCBAs staged for use in the Unit 3 turbine building, and two SCBAs staged in the Unit 2 Technical Services Area.
 
Maintenance and regulator test records were reviewed for selected SCBAs. The inspector also evaluated whether the air used to fill the SCBAs met the Grade D quality criteria of the Compressed Gas Association.The inspectors evaluated the licensee's program for assuring quality in the radiationmonitoring instrumentation and respiratory protection programs by reviewing self-assessments (MP-SA-06-56/69/74/79), Nuclear Oversight audits (Nos.05-06, 06-04/08, 07-06), and 21 CRs related to these program areas. The inspector determined if problems were identified in a timely manner, that an extent of condition and cause evaluation were performed, previous radiation surveys remained valid, and corrective actions were appropriate to preclude repetitive problems.

===.2 Annual Sample: Safety Injection Tank (SIT) Leakage===
  (One Sample)
 
====a. Inspection Scope====
The inspectors reviewed the actions taken by Dominion to evaluate and correct severalinstances of valve leakage that impacted SIT accumulator water levels and/or boron concentration over the past several years of operation. The inspectors reviewed CRs related to SIT accumulator leakage, the completed evaluations, and associated corrective actions to assess the performance history and effectiveness of Dominion's actions. The inspectors conducted interviews with plant personnel. The inspectors also reviewed procedures, data and drawings. b.Assessments and ObservationsNo findings of significance were identified. The inspectors concluded that Dominion hadadequately evaluated and corrected the various individual valve leakage issues.
 
However, the inspectors noted that engineers and operators were challenged by the multiple system/valve leaks over the last several years. In particular, operator actions were necessary to frequently fill the affected SIT accumulators or to depressurize an associated accumulator fill header (via a temporary modification). Engineers and operators also developed and executed troubleshooting plans to identify leaking components. Although the past problems have not resulted in rendering the SIT accumulator or related emergency cooling systems inoperable, continued leaks represent challenges to plant equipment and staff. Dominion management acknowledged the concerns related to the continuing challenges, and discussed some of their ongoing and planned efforts to broadly address and evaluate additional proactive measures to prevent further leakage problems, including an inter-discipline review of the potential leakage paths and scenarios.4OA6Meetings, Including ExitOn September 14, 2007, the EP inspector presented the inspection results to Mr. J.

SUMMARY OF FINDINGS

IR 05000336/2007-004, 05000423/2007-004; 07/01/2007 - 09/30/2007; Millstone PowerStation, Unit 2 and Unit 3; Post-Maintenance Testing.The report covered a 3-month period of inspection by resident inspectors and announcedinspections by regional inspectors. One Green finding was identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.A.

NRC-Identified and Self-Revealing Findings

Cornerstone: Initiating Events

Green.

A self-revealing finding was identified for Dominion's failure to implementprocedure OP 3330B, "Turbine Plant Component Cooling Water" during restoration of the "B" turbine plant component cooling water (TPCCW) heat exchanger on August 28, 2007. Specifically, following maintenance that left the heat exchanger shell in a partially drained condition, Dominion did not fill and vent the heat exchanger in accordance with OP 3330B. This resulted in two of the three TPCCW pumps receiving an automatic trip signal on low suction pressure. Loss of the remaining TPCCW pump would have required the operators to manually trip the reactor within three minutes per plant procedures. Dominion entered this issue into their corrective action program as CR-07-09057. Corrective actions included revising OP 3330B to require the fill and vent section be used following maintenance to ensure the TPCCW side of the heat exchanger is completely full of water, and revising the work planning procedure to request operations work planning provide restoration packages for all applicable work orders. This finding is more than minor because it was associated with the human performanceattribute of the Initiating Events Cornerstone and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Dominion's failure to implement the fill and vent procedure, when required by heat exchanger conditions, could potentially have led to the loss of all TPCCW pumps and required operators to manually trip the reactor. This finding was determined to be of very low safety significance (Green) by performing a Phase 1 evaluation in accordance with NRC IMC 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. The finding has a cross-cutting aspect in the area of Human Performance, work practices component, because Dominion did not implement proper procedures for the restoration of the "B" TPCCW heat exchanger.

b. Findings

Introduction:

A self-revealing finding was identified for Dominion's failure to implementprocedure OP 3330B, "Turbine Plant Component Cooling Water," during restoration of the "B" TPCCW heat exchanger on August 28, 2007. Specifically, Dominion did not fill and vent the heat exchanger in accordance with OP 3330B following maintenance that left the heat exchanger shell in a partially drained condition. This resulted in two of the three TPCCW pumps receiving an automatic trip signal on low suction pressure. Plant 10Enclosureprocedures would have required the operators to manually trip the reactor within threeminutes had the third TPCCW pump tripped.Description: On August 8, 2007, Dominion identified a tube leak originating from the "B"TPCCW heat exchanger. Dominion prepared a work package to identify and repair the source of the leak. On August 27, Dominion personnel began work on repairing the TPCCW heat exchanger. A leaking tube was identified near the bottom of the heat exchanger, and the leak rate was estimated to be approximately one half gallon per minute at that time. Dominion successfully completed the repairs to the heat exchanger on August 28. During restoration of the heat exchanger, when operators opened the "B" TPCCW heatexchanger discharge isolation valve, the "C" TPCCW pump immediately tripped on low suction pressure. The "B" TPCCW pump, which was in standby, also received an automatic trip signal on low suction pressure, preventing the pump from starting. The "A" pump, which was running, did not receive a trip signal and remained in operation.

Heat loads on the TPCCW system at full power require at least two pumps to be in service. The plant operated with only one TPCCW pump running for approximately five minutes, during which time lube oil temperatures increased and a generator bus duct cooling system high temperature alarm was received. Operators were able to restart the "B" TPCCW pump within five minutes, which provided sufficient cooling to the TPCCW system. Dominion's investigation determined that the TPCCW side of the heat exchanger hadbeen slowly draining through the failed tube since August 8, when the heat exchanger was first isolated. Restoring the "B" TPCCW heat exchanger while in a substantially drained condition resulted in two of the three TPCCW pumps receiving automatic trip signals on low suction pressure, and could have potentially also led to a trip signal beingsent to the only remaining TPCCW pump. The performance deficiency is that Dominion failed to implement procedure OP 3330B, Section 4.8, "Filling TPCCW Heat Exchanger(s)", when required by heat exchanger conditions following maintenance to repair a tube leak.Analysis: As a result of not implementing OP 3330B, Section 4.8, "Filling TPCCW HeatExchanger(s)," Dominion restored the "B" TPCCW heat exchanger while in a substantially drained condition, which resulted in the "B" and "C" TPCCW pumps receiving automatic trip signals on low suction pressure. This finding is more than minor because it was associated with the human performance attribute of the Initiating Events Cornerstone and affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, Dominion's failure to implement the fill and vent procedure, when required by heat exchanger conditions, could potentially have led to the loss of all TPCCW pumps and required operators to manually trip the reactor. The inspectors conducted a Phase 1 screening of the finding in accordance with IMC0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations." The finding was determined to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available.

11EnclosureThe performance deficiency has a cross-cutting aspect in the area of HumanPerformance, Work Practices, in that Dominion did not implement proper procedures for the restoration of the "B" TPCCW heat exchanger. H.4(b)]Enforcement: Enforcement action does not apply because the performance deficiencydid not involve a violation of regulatory requirements because the TPCCW system is not safety-related equipment. Dominion entered this issue into their corrective action program (CR-07-09057). Corrective actions include revising the work planning procedure to request Operations Work Planning provide restoration packages for all applicable work orders, and revising OP 3330B to require the fill and vent section be used following maintenance to ensure the TPCCW side of the heat exchanger is completely full of water. Because this finding does not include a violation of regulatoryrequirements and is of very low safety significance (Green), it is identified as FIN05000336/2007004-01, Failure to Perform Fill and Vent of TPCCW Heat ExchangerResulted in Loss of Two TPCCW Pumps.

1EP4 Emergency Action Level (EAL) and Emergency Plan Changes

a. Inspection Scope

(One Sample)Since the last NRC inspection of this program area, the latest Emergency Plan Revisionwas implemented based on Dominion's determination, in accordance with 10 CFR 50.54(q), that the changes resulted in no decrease in effectiveness of the Plan, and that the revised Plan continued to meet the requirements of 10 CFR 50.47(b) and Appendix E to 10 CFR 50. The inspector conducted a sampling review of the Emergency Plan changes, and all changes to EALs, to evaluate for potential decreases in effectiveness of the Emergency Plan. However, this review was not documented in a Safety Evaluation Report and does not constitute formal NRC approval of the changes.

Therefore, these changes remain subject to future NRC inspection in their entirety.

b. Findings

a. Inspection Scope

(Nine samples)During the period September 24-28, 2007, the inspectors conducted the followingactivities to evaluate the operability and accuracy of radiation monitoring instrumentation, and the adequacy of the respiratory protection program, relative to maintaining and issuing self-contained breathing apparatus (SCBA). Implementation of these programs was reviewed against the criteria contained in 10 CFR 20, applicable industry standards, and Dominion's procedures. The inspectors reviewed the UFSAR to identify area radiation monitors that are installedin Millstone Units 2 and 3 for the protection of workers, and reviewed the calibration procedure and current calibration records for selected instrumentation, including the Unit 2 spent fuel area monitors (RM-8139/8142/8156/8157), the Unit 3 spent fuel pool area monitors (3RMS-RIY08/36) and the Unit 3 containment area monitors (RE-01/02/03). The inspector discussed with the Instrument and Control (I&C)supervisor the monitoring system health report and instrument reliability trends. The inspector reviewed the operating procedure and current source activities/dose ratecharacterizations for the Shepherd Model 89 instrument calibrators (Serial Nos. 9155 &

9068). The inspector observed a technician perform safety interlock testing on the calibrator prior to using it.

15EnclosureThe inspector reviewed the calibration records for selected survey instruments andcontamination monitors including the small article contamination monitors (SAM 9 & 11),personnel contamination monitors (ARGOS-4A/B), electronic dosimeters (SeimensMk2), and various portable survey instruments (FH40TC, RO-2A, RO-20).The inspector reviewed the relevant procedures and observed a technician performing acalibration validation on electronic dosimeters and calibrate portable radiation survey instruments (RO-2A & RO-20).The inspector observed a technician performing daily functional checks on a variety ofcontamination monitors and survey instruments located in Units 2 and 3 including SAC-4, SAM-11, ARGOS 4A/B, CM-11, RM-14, Ludlum 177, BC-4, and Teleprobes.

The inspector reviewed the procedure and quality control records associated with performing the instrument daily functional checks, including air sample counting equipment and gamma spectrometers.The inspector reviewed recent contamination sampling (10 CFR 61 data) results forUnits 2 and 3 to determine if the instrument calibration sources used were representative of the radioisotopes found in the plant source term.The inspector evaluated the adequacy of the respiratory protection program regardingthe maintenance and issuance of SCBA to emergency response personnel. Training and qualification records were reviewed for licensed operators from each of the five operating shifts at each unit and for selected response personnel who would wear SCBAs in the event of an emergency. The inspector, with the assistance of Fire Protection technicians, physically inspectedthree SCBAs staged for use in each control room, two SCBAs staged for use in the Unit 3 turbine building, and two SCBAs staged in the Unit 2 Technical Services Area.

Maintenance and regulator test records were reviewed for selected SCBAs. The inspector also evaluated whether the air used to fill the SCBAs met the Grade D quality criteria of the Compressed Gas Association.The inspectors evaluated the licensee's program for assuring quality in the radiationmonitoring instrumentation and respiratory protection programs by reviewing self-assessments (MP-SA-06-56/69/74/79), Nuclear Oversight audits (Nos.05-06, 06-04/08, 07-06), and 21 CRs related to these program areas. The inspector determined if problems were identified in a timely manner, that an extent of condition and cause evaluation were performed, previous radiation surveys remained valid, and corrective actions were appropriate to preclude repetitive problems.

b. Findings

No findings of significance were identified.

.2 Annual Sample: Safety Injection Tank (SIT) Leakage

(One Sample)

a. Inspection Scope

The inspectors reviewed the actions taken by Dominion to evaluate and correct severalinstances of valve leakage that impacted SIT accumulator water levels and/or boron concentration over the past several years of operation. The inspectors reviewed CRs related to SIT accumulator leakage, the completed evaluations, and associated corrective actions to assess the performance history and effectiveness of Dominion's actions. The inspectors conducted interviews with plant personnel. The inspectors also reviewed procedures, data and drawings. b.Assessments and ObservationsNo findings of significance were identified. The inspectors concluded that Dominion hadadequately evaluated and corrected the various individual valve leakage issues.

However, the inspectors noted that engineers and operators were challenged by the multiple system/valve leaks over the last several years. In particular, operator actions were necessary to frequently fill the affected SIT accumulators or to depressurize an associated accumulator fill header (via a temporary modification). Engineers and operators also developed and executed troubleshooting plans to identify leaking components. Although the past problems have not resulted in rendering the SIT accumulator or related emergency cooling systems inoperable, continued leaks represent challenges to plant equipment and staff. Dominion management acknowledged the concerns related to the continuing challenges, and discussed some of their ongoing and planned efforts to broadly address and evaluate additional proactive measures to prevent further leakage problems, including an inter-discipline review of the potential leakage paths and scenarios.4OA6Meetings, Including ExitOn September 14, 2007, the EP inspector presented the inspection results to Mr. J.
