2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 INTRODUCTION This report is submitted pursuant to Specification 6.9.1.8 of St. Lucie Unit 1 and St. Lucie Unit 2 Technical Specifications. The Annual Radiological Environmental Operating Report provides information, summaries and analytical results pertaining to the radiological environmental monitoring program for the calendar year indicated. This report covers surveillance activities meeting the requirements of Unit 1 and Unit 2 Technical Specifications.

This amendment involves the completion and reporting of cycle MAPEP-1 8 of the Interlaboratory Comparison Program results.

II. RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM A. Purpose The purpose of the radiological environmental monitoring program is to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides which lead to the highest potential radiation exposures to members of the public resulting from station operation. The radiological environmental monitoring program also supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

B. Progqram Description The radiological environmental monitoring program (REMP) for the St. Lucie Plant is conducted pursuant to the St. Lucie Units 1 and 2 Offsite Dose Calculation Manual (ODCM) Section 3/4.12.1.,

Monitoring Program.

1. Sample Locations, Types and Frequencies:
a. Direct radiation gamma exposure rate is monitored continuously at 27 locations by thermoluminescent dosimeters (TLDs). TLDs are collected and analyzed quarterly.
b. Airborne radioiodine and particulate samplers are operated continuously at five locations. Samples are collected and analyzed weekly. Analyses include Iodine-1 31, gross beta, and gamma isotopic measurements.
c. Surface water samples are collected from two locations. Samples are collected and analyzed weekly and monthly, respectively. Analyses include gamma isotopic and tritium measurements.

2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2

d. Shoreline sediment samples are collected from two locations coinciding with the locations for surface water samples. Samples are collected and analyzed semi-annually. Sediment samples are analyzed by gamma isotopic measurements.
e. Fish and invertebrate samples are'collected from two locations. Samples are collected and analyzed semi-annually. Fish and invertebrate samples are analyzed by gamma isotopic measurements.
f. Broad leaf vegetation samples are collected from three locations. Samples are collected and analyzed monthly. Broad leaf vegetation samples are analyzed by gamma isotopic measurements.
g. Ground Water, NEI Initiative; there were no ground water sampling locations in the REMP for 2007 Attachment A provides specific information pertaining to sample locations, types and frequencies.
2. Analytical Responsibility:

Radiological environmental monitoring for the St. Lucie Plant is conducted by the State of Florida, Department of Health (DOH), Bureau of Radiation Control (BRC).

Samples are collected and analyzed by DOHpersonnel.

Samples are analyzed at the DOH BRC Environmental Radiation Control Laboratory in Orlando, Florida.

C. Analytical Results Table 1, Environmental Radiological Monitoring Program Annual Summary provides a summary for all specified samples collected during the referenced surveillance period.

Deviations from the sample schedule or missing data, if any, are noted and explained in Table 1A. Samples not meeting the specified "A PRIORI" LLD, if any, are noted and explained in Table 1B. Analysis data for all specified samples analyzed during the surveillance period is provided in Attachment B.

2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS 1 & 2 D. Land Use Census A land use census out to a distance of a five mile radius from the St. Lucie Plant is conducted annually to determine the location of the nearest milk animal, residence, and garden producing broad leaf vegetation, in each of the 16 meteorological sectors. A summary of the land use census for the surveillance year is provided in Table 2, Land Use Census Summary.

E. Interlaboratory Comparison Program The intercomparison program consists of participating in the DOE Mixed Analyte Performance Evaluation Program (MAPEP).

This program provides similar testing (matrices, nuclides, and levels) as the former EPA Interlaboratory Comparison Program and is referred to as the Mixed Analyte Performance Evaluation Program (MAPEP).

The samples are analyzed using the methods applicable to the REMP (gamma spectroscopy, Gross Beta, and Tritium for water).

From the MAPEP handbook:

Acceptance criteria were developed from a review of precision and accuracy data compiled by other performance evaluation programs (PEPs), the analytical methods literature, from several MAPEP pilot studies, and from what is considered reasonable, acceptable, and achievable for routine analyses among the more experienced laboratories.

The results for nuclides associated with the REMP are listed in ATTACHMENT C, RESULTS FROM THE INTERLABORATORY COMPARISON PROGRAM.

2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 Ill. DISCUSSION AND INTERPRETATION OF RESULTS A. Reportingq of Results The Annual Radiological Environmental Operating Report contains the summaries, interpretations and information required by St. Lucie Plant ODCM. Table 1 provides a summary of the measurements made for the nuclides required by ODCM, Table 4.12-1, for all samples specified by Table 3.12-1. In addition, summaries are provided for other nuclides identified in the specified samples, including those not related to station operation.

These include nuclides such as K-40, Th-232, Ra-226, and Be-7, which are common in the Florida environment.

B. Interpretation of Results

1. Direct Radiation:

The results of direct radiation monitoring are consistent with past measurements for the specified locations. The exposure rate data shows no indication of any trends attributed to effluents from the plant. The measured exposure rates are consistent with exposure rates that were observed during the pre-operational surveillance program. Direct radiation monitoring results are summarized in Table 1.

2. Air Particulates/Radioiodine:

The results for radioactive air particulate and radioiodine monitoring are consistent with past measurements and indicate no trends attributed to plant effluents. All samples for radioiodine yielded no detectable 1-131. Gamma isotopic measurements yielded no indication of any nuclides attributed to station operation.

The results for air particulate/radioiodine samples are consistent with measurements that were made during the pre-operational surveillance program. Air particulate and radioiodine monitoring results are summarized in Table 1.

3. Surface Water:

The results for radioactivity measurements in surface water are consistent with past measurements and with measurements made during the pre-operational surveillance program. There were no indications of any nuclides attributed to plant effluents. Results for surface water samples are summarized in Table 1.

4

2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2

4. Waterbome Sediment and Food Products:

The results for radioactivity measurements in waterborne sediment, fish and crustacean samples are consistent with past measurements and with measurements made during the pre-operational surveillance program. There were no indications of any nuclides attributed to plant effluents. Results for the waterborne sediment, fish and crustacean samples are summarized in Table 1.

5. Broad Leaf Vegetation:

The results of radioactivity measurements in broad leaf vegetation are consistent with past measurements and with measurements made during the pre-operational surveillance program.

There were no indications of any nuclides attributed to plant effluents.

Results for the broad leaf vegetation samples are summarized in Table 1.

6. Land Use Census:

No locations yielding a calculated dose or dose commitment greater than the values currently being calculated were identified by the land use census. No locations yielding a calculated dose or dose commitment (via the same exposure pathway) 20 percent greater than locations currently being sampled in the radiological environmental monitoring program were identified by the land use census.

7. Interlaboratory Comparison Program:

The State laboratory participated in MAPEP 17 and 18.

In MAPEP 17, the results for Water, Soil and Vegetation matrices forthose nuclides associated with nuclear power plant operation and using analytical methods used in the REMP are Acceptable. The Air Filter matrix had a not acceptable for Co-57; the lab result was high. Co-57 is not a nuclide seen in the history of air sampling around the nuclear power plants in Florida. Review of assay methods did not reveal a definitive cause; repeat counting of the sample yielded what would be acceptable results. The Co-57 calibration standard is being replaced.

For MAPEP 18, the State Laboratory received, analyzed & reported their results; however, DOE has reported a delay for issuance of the report that would contain the performance grade. The report was published late April / early May 2008.

The results for Water, Air Filter and Vegetation matrices for those nuclides associated with nuclear power plant operation and using analytical methods used in the REMP are Acceptable with a warning for Am-241 in vegetation.

The Soil matrix had a not acceptable for Co-60. An evaluation was performed; the conservative result was due to interference from the presence of Cs-134 in a sample that has very little Co-60. The assay algorithm has been corrected to account for this in the future. The history of soil sampling was reviewed; as expected, there has not been a case of positive Cs-1 34 in a sample.

2007 AMENDED ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT ST. LUCIE PLANT - UNITS I & 2 C. Conclusions The data obtained through the St. Lucie Plant radiological environmental monitoring program verifies that the levels of radiation and concentrations of radioactive materials in environmental samples, representing the highest potential exposure pathways to members of the public, are not being increased.

The measurements verify that the dose or dose commitment to members of the public, due to operation of St. Lucie Units 1 and 2, during the surveillance year, are well within "as low as reasonably achievable (ALARA)" criteria established by 10 CFR 50, Appendix I.

NOTES

a. The LLD is an "a priori" lower limit of detection which establishes the smallest concentration of radioactive material in a sample that will yield a net count above system background that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a real signal.

LLDs in this column are at time of measurement. The MDAs reported in Attachment B for the individual samples have been corrected to the time of sample collection.

b. Mean and range based upon detectable measurements only. Fraction of detectable measurements at specified locations is indicated in parentheses (f).
c. Specific identifying information for each sample location is provided in Attachment A.
d. Results were based upon the average net response of three elements in a TLD (thermoluminescent~dosimeter).

MDA refers to minimum detectable activity.
