Dear Mr. Haas:

On October 18, 2006, the NRC completed inspection activities at the Big Rock PointRestoration Project. The purpose of the inspection was to conduct radiological confirmatory surveys and evaluate the biennial exercise of the Emergency Plan. At the conclusion of on-siteinspection on October 18, the inspectors discussed the inspection findings with you and members of your staff. This inspection consisted of independent radiological confirmatory surveys of areas of the BigRock Point site that had not been previously surveyed by the NRC, and the observation and evaluation of the Independent Spent Fuel Storage Installation (ISFSI) Emergency Plan exercise. Areas examined during the inspection are identified in the enclosed report. Within these areas, the inspection included a selective examination of procedures and representative records, observations of activities in progress, and interviews with personnel.Based on the results of this inspection, the NRC did not identify any violations.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letterand its enclosure will be available electronically in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). The NRC's document system is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.

K. Haas-2-We will gladly discuss any questions you may have regarding this inspection.

Sincerely,

3EnclosureReport Details 11.0Operation of an ISFSI (60855)1.1Inspection ScopeThe inspectors observed and evaluated the conduct of the Independent Spent FuelStorage Installation (ISFSI) Emergency Plan biennial exercise.1.2Observations and FindingsSection 12.2.2 of Volume 35 of the ISFSI Emergency Plan requires the licensee toperform a biennial exercise to demonstrate emergency response capabilities and the effectiveness of the Emergency Plan. On October 17, 2006, the licensee conducted a biennial exercise based on a simulated earthquake that caused a spent fuel storage cask to tip over. In response to the event, the license appropriately implemented the Emergency Plan, correctly classified the event, augmented personnel as necessary, made timely notifications, conducted appropriate radiological monitoring, and ensured the safety of site personnel.1.3ConclusionThe licensee adequately demonstrated the effectiveness of the ISFSI Emergency Planand their ability to implement the Plan in response to an emergency.2.0Inspection of Final Surveys (83801)2.1Inspection ScopeThe inspectors performed independent radiological confirmatory surveys of selected on-site areas. Licensee records of final status surveys were also reviewed. 2.2Observations and FindingsIndependent radiological gamma scan surveys were performed of the following surveyareas using sodium iodide (NaI) scintillation detectors coupled to ratemeters with audible indication: South11C 11 (50% scanned); 20C 11 (80% scanned); South19C 1 2(30% scanned); North21C 12 (50% scanned); eastern 20% of East22C 12 (50% scanned);and an area of about 50 square meters in the northeast corner of 18C 13 (50% scanned). In all areas surveyed, the inspectors did not identify elevated levels of direct gamma radiation in excess of background.

4EnclosureThe following nine licensee final status survey records were reviewed, which includedthe Survey Area Requirements, Data Quality Objects, and the Final Status Survey (FSS)

For the above South Radwaste Staging Area (South11C 11), and Southwest Transport Route (South19C 12), the licensee's surveyscan results and the analytical results of soil samples were also reviewed. The final status survey soil sample results reviewed showed less than the derived concentration guideline levels (DCGLs) for soil of 11.93 picocuries per gram (pCi/g) for cesium-137 and 3.21 pCi/g for cobalt-60 as described in the licensee's License Termination Plan (LTP). The licensee's scan surveys indicated no elevated direct gamma radiation in excess of background2.3ConclusionA review of licensee survey records and independent confirmatory surveys for residualradioactive contamination confirmed that the licensee is performing remediation and final status surveys consistent with the LTP.3.0Exit Meeting SummaryThe inspectors presented preliminary inspection findings to members of the licenseemanagement team at the conclusion of onsite inspection activities on October 18, 2006.ATTACHMENT: SUPPLEMENTAL INFORMATION AttachmentSUPPLEMENTAL INFORMATIONPARTIAL LIST OF PERSONS CONTACTEDConsumers Energy Company* Kurt Haas, Site General Manager* Ken Pallagi, Radiation Protection & Environmental Services Manager* Persons present at the exit meetings.INSPECTION PROCEDURES USEDIP 60855Operation of an ISFSIIP 83801Inspection of Final Surveys at Permanently Shutdown ReactorsITEMS OPENED, CLOSED, AND DISCUSSEDOpened None Closed None Discussed NonePARTIAL LIST OF DOCUMENTS REVIEWEDLicensee documents reviewed and utilized during the course of this inspection are specificallyidentified in the "Report Details" above.LIST OF ACRONYMS USEDADAMSAgencywide Documents Access and Management SystemDCGL Derived Concentration Guideline Level DNMSDivision of Nuclear Materials Safety FSSFinal Status Survey ISFSIIndependent Spent Fuel Storage Installation LTPLicense Termination Plan NRCNuclear Regulatory Commission pCi/g picocuries per gram Attachment 6
