Sea Turtle Entra ment Stud The enclosed report is being submitted pursuant to the requirements of Section 4.2.2.2 (7) of the St. Lucie Units 1 and 2 Environmental Protection Plans. The report provides the results of a study to elucidate the effect of various factors on sea turtle entrapment at the St. Lucie Plant. The study of turtle entrapments at the St. Lucie Plant intake canal was required by condition 7 of the Incidental Take Statement (ITS) of the National Marine Fisheries Service (NMFS) Biological Opinion (BO) dated February 7, 1997. The FPL study proposal was approved by the NMFS and the NRC by NRC letter dated February 22, 1999.

FPL's request for a Section 7 Consultation resulted in a meeting November 10, 1999, with FPL, NRC, NMFS, and Florida Fish and Wildlife Commission (FFWC) personnel. In this meeting, FPL was requested to include a discussion of the alternatives evaluated over the years to reduce sea turtle entrapment in the intake canal when the enclosed study was submitted. Tins discussion is attached.

'reen Turtle Lethal Take Discussion There were a total of four green turtle mortalities at St. Lucie Plant in 1999. The present National Marine Fisheries Service (NMFS) designated lethal take limit for this species at St. Lucie is 3 or 1.5%, whichever is greater. A total of 190 green turtles were removed from the canal during 1999, yielding a green turtle mortality rate of 2.1% for the year. Three of the four mortalities occurred in September of 1999 following the passage of Hurricane Dennis and Hurricane Floyd.

Concurrent with these events, there were large influxes of drift algae that accumulated on the primary barrier net, which forced the lowering of the net for several days. It was difficult to ascertain if any of these three mortalities were directly related to conditions encountered in the canal itself.

Exceeding the Lethal Take Limit requires reinitiating of a Section 7 Consultation between NRC and NMFS. FPL's request for a Section 7 Consultation resulted in a meeting November 10, 1999 with FPL, NRC, NMFS, and Florida Fish and Wildlife Commission (FFWC) personnel. This meeting also satisfied the biannual meeting with these agencies required by the plant Environmental Protection Plan, Section 4.2.2.2.10) c). Data presented by FPL during the November 1999 meeting indicates that over the entire period since consultation was initiated, green turtle mortalities were below the 1.5% level. Individual years (1997 and 1999) have exceeded the take limit and reinitiated consultation. In both 1997 and 1999, higher mortalities were associated with hurricanes and jellyfish influxes. It appears that these essentially random and uncontrollable events caused'"spikes" in mortality levels that triggered reinitiating of consultation.

Thus, while overall the conservation program is effective in achieving the take limit goals, the trigger to reinitiate consultation is perhaps too sensitive.

FPL proposes that individual year limits be set higher, at 6 green turtles or 3%, with a "lifetime" program limit of 1.5%. In support of the above request, FPL would like to reiterate the effectiveness of the sea turtle protection program at the St. Lucie Plant. This program includes the following current activities:

1. The Canal Capture and Release Program - This program has included over 6,500 turtles that "

have been captured, biological information recorded, tagged, and released back to the environment. The program has provided an invaluable source of population information for Loggerhead and Green Turtle populations, including immature individuals, on the East Coast of Florida. It also serves as a method of capture and rehabilitation of injured or diseased sea turtles that enter the intake canal.

2. The Beach Nesting Survey Program - This program includes a daily survey of sea turtle nests on Hutchinson Island. In 1999, over 7,400 nests were identified to species and counted. This data provides another invaluable tool toward monitoring the long-term trends of Loggerhead, Green, and Leatherback Turtle reproductive populations in the area.

3. The Public Service Turtle Walk Program - This program included 26 Turtle Walks in 1999 and involved approximately 1,100 members of the public. The pmgram is a highly effective tool toward promoting sea turtle protection awareness.

4. Participation in the Sea Turtle Stranding and Salvage Network - In 1999, FPL responded to approximately 30 sea turtle strandings in the local area. This program supports the monitoring of sea turtle disease, injury, and mortality. Ifnecessary, injured or diseased turtles are transported to rehabilitation facilities where they can be treated and released back to the environment.

In addition to the above programs, FPL has initiated many efforts to reduce plant impact on local sea turtle populations. These efforts include studies to reduce turtle entrapment in the canal as well as the development of methods to reduce residence time and mortalities in the canal. These efforts include several deterrent studies, which were conducted during the early to mid-1980's.

Deterrent technologies, such as strobe lights, bubble-curtains, electrical fields, and pneumatic guns were tested, but none proved to be effective in the offshore environment.

Several physical barrier designs and possible deterrents for the ocean intakes were also considered during the 1980's when the average size of turtle captured in the canal was much larger than the small green turtles that have been captured recently. These alternatives posed potential environmental concerns. These concerns include but are not limited to a net or barrier could become a floating "menace" in the Atlantic Ocean, as well as concerns about animals getting impinged on these devices. Previous analysis of those designs indicated that the capital and maintenance costs for a physical barrier system would be prohibitive and could likely cause a reduction in intake canal flow. In that the grid size of such a barrier would have to be even smaller to prevent entrapment today, such a design would appear to be even less feasible. Other investigations included methods of modifying turtle behavior with lights, air bubble curtains, sound, or electrical current so that the sea turtles would not approach or enter the intake structure.

These studies were completed in 1985 and were submitted to the NRC by FPL letter L-85-158 dated April 18, 1985.

The most effective technology developed to date has been the installation of the 5-inch mesh barrier net just downstream of the canal headwall. This barrier net, which was installed in 1996, is an effective method of reducing residency time in the canal and therefore, the probability of injury or death to entrapped turtles.

At NMFS request, FPL commissioned a study in 1999 to investigate factors that might be important in the entrapment of sea turtles at the St. Lucie Plant. This effort is an excellent summary of canal capture information to date, plus it includes an analysis of many physical factors in the environment that could effect sea turtle entrapment. This study indicates that increased entrapment rates of turtles are most likely due to increases in sea turtle populations in the area offshore of the plant and not any change in plant operating characteristics.

Mr. J. A. Stall Site Vice President St. Lucie Nuclear Plant Florida Power and Light Company 6351 S. Ocean Drive Jensen Beach, FL 34957

Dear Mr. Stall,

This letter is in regard to the proposed study of turtle entrapments at the St. Lucie plant intake canal as required by condition 07 of the incidental take statement (ITS) of the February 7, 1997, biological opinion (BO). The BO was the result of the Section 7 consultation under the Endangered Species Act. In a letter dated May 8, 1998, the National Marine Fisheries Service (NMFS) provided the Nuclear Regulatory Commission (NRC) with revisions to the ITS of the BO. The revisions request FPL to propose a study and obtain NMFS approval prior to implementing the study. By fetter dated June 17, 1998, NRC forwarded the revisions of the ITS to FPL and requested the St. Lucie plant implement the revised provisions in its Environmental Protection Plans. FPL provided the proposed changes to the St. Lucie Environmental Protection Plans implementing the ITS to NRC by letter dated August 26, 1998. By letter dated October 7, 1998, NRC forwarded FPL's draft request for proposal to design and implement a study to elucidate the effect of various factors on turtle entrapment to NMFS for review and approval.

NMFS has reviewed FPL's proposal for the turtle study and has concluded that it is acceptable.

FPL should proceed with implementation of the study. Once a contract is in place, FPL should provide quarterly progress reports on the turtle study to NMFS. The ITS states the final report is to be completed by December 31, 1999. However, because the contract has not yet been placed, this date is not likely to be met, Therefore, once the contract is in place and the quarterly reports are being submitted, please provide a completion date for the final report. The NRC staff anticipates a date of completion of the study to be sometime in March 2000. This allows approximately two months for proposal solicitation, one month for contract awarding, six months for creating a draft report, and three months for finalizing the report. If you have any further questions regarding this matter please contact Ms. Claudia Craig at 301-415-1053.

1996 ANNUALRADIOLOGICAL ENVIRONIVIENTALOPERATING REPORT ST. LUCIE PLANT - UNITS 1 & 2 D.

A land use census out to a distance of 5 miles 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 sixteen meteorological sectors. A summary of the land use census for the surveillance year is provided in Xa~, LaadMse~nsus Summary..

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% greater than locations currently being sampled in the radiological environmental monitoring program were identified by the land use census.

The State of Florida DOH Environmental Radiation Control Laboratory participates in the Environmental Radioactivity Laboratory Intercomparison Studies Program conducted by the Environmental Protection Agency. Results from the Interlaboratory Comparison Program are provided in Attachment C.

DISCUSSION AND INTERPRETATION OF RESULTS A.

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.

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 preoperational 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 I-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 which were made during the preoperational surveillance program. Air particulate and radioiodine monitoring results are summarized in Table 1.

3. Surface Water:

The results of radioactivity measurements in surface water samples are consistent with past measurements. Tritium was reported as present in four of the weekly samples collected from Site H-15. The highest concentration was less than 1% of the reporting level specified by the ODCM, Table 3.12-2. No other nuclides attributed to station operation were detected. Results for surface water samples are summarized in Table 1.

4. Waterborne Sediment and Food Products:

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

1996 ANNUAL RADIOLOGICAL ENVIRONMENTALOPERATING REPORT ST. LUCIE PLANT - UNITS 1 6 2

5. Broad Leaf Vegetation The results of radioactivity measurements in broad leaf vegetation are consistent with past measurements and with measurements made during the preoperational 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.

C.

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 & 2, during the surveillance year, are well within "as low as reasonably achievable (ALARA)" criteria established by 10 CFR 50, Appendix I.
