ENCLOSURE INDEPENDENT SPENT FUEL STOWAGE INSTALLATION ANNUAL RADIOACTIVE EFFLUENVEQEASEREPORT BlG ROCK POINT January "iihr~ughDecember 01,2007 I. FACILITY DESCRIPTION The Independent Spent Fuel Storage Installation (ISFSI) is located within the owner-controlled area of the Big Rock Point (BRP) site. The storage of spent fuel at BRP meets the requirements of 10 CFR 72, and the Certificate of Compliance No. 72-1026, issued by the Nuclear Regulatory Commission (NRC).

II. EFFLUENT LIMITS AND CONTROLS The ISFSI operates under effluent control limits as required by 10 CFR 72.104.

However, the design of the sealed storage canisters at the ISFSl precludes any gaseous or liquid effluent releases.

Ill. RADIOLOGICAL EFFLUENT RELEASES As noted in Section II, by design, there are no radioactive liquid or gaseous effluents originating from the ISFSl facility. The annual radiological surveillance performed during this reporting period did not indicate any release of radioactivity from the ISFSI.

IV. ISFSl ENVIRONMENTAL MONITORING PROGRAM The BRP Radiological Environmental Monitoring Program (REMP) is described in the Offsite Dose Calculation Manual (ODCM),Section I, Subsection 4.0. The ISFSl Environmental Monitoring Program, which is contained within the BRP REMP, consists of thermoluminescent dosimeters (TLDs) at four locations along the perimeter of the ISFSI site, and three control TLDs 10.5 to 50 miles from the site.

Annual TLDs are read annually and quarterly TLDs are read quarterly as reflected in Table 1. Annual and quarterly measurements are compared to control measurements to evaluate compliance with 10 CFR 72.104. The results for the lSFSl TLDs and the average of the control TLDs measured in 2007 are summarized in the following table.

There were no sample anomalies for 2007.
