In response to U. S. Nuclear Regulatory Commission staff's (NRC staff's) Request for Additional Information (RAI) HC-7 (RAls: Agencywide Documents Access and Management System (ADAMS) Accession No. ML 18190A499; Florida Power and Light's response:

ADAMS Accession No. ML 18247A507), Florida Power & Light Company (FPL) identified that within the 9,460-acre Turkey Point site exist three (3) wooden structures that were part of a Boy Scout Camp, and a cottage (known as the Ranger House or the McGregor Smith Cottage).

The response states that there is no known historical significance of the three Boy Scout structures, and that they do not appear to meet the criteria for listing in the National Register of Historic Places (NRHP). However, the RAI response also states that these three structures have not been evaluated for NRHP eligibility and information about these structures has not been recorded by an architectural historian that meets the Secretary of Interior standards.

Regarding the McGregor Smith Cottage, the RAI response indicated that the cottage does not appear to have distinguishing features, and its association with McGregor Smith is unknown. The RAI response further indicated that although FPL initiated activities in 2012 to determine the eligibility of the cottage for historic landmark status and potential restoration, a NRHP determination has not been completed.

The NRC staff subsequently identified the possible existence of a report prepared by David Baber, Architectural Historian, Historic Preservation Solutions, LLC, regarding the McGregor Smith Cottage Preservation Project that analyzes the historical context of the cottage. This report may provide insight as to the eligibility of the cottage for listing the in the NRHP. The NRC staff does not have a copy of this report. According to Protection of Historic Properties regulations in 36 CFR 800.4(c), the NRC . is required to determine whether the three Boy Scout structures and the McGregor Smith Cottage are historic properties eligible for listing in the NRHP in accordance with criteria in 36 CFR Part 63. In addition, regulations in 36 CFR 800.1 (c), Timing, states, "The agency official must complete the section 106 process 'prior to the ... issuance of any license."'

1. On August 28, 2018 the NRC staff held a Category 1 public meeting with FPL to discuss the responses provided in HC-7. Provide the following information discussed during the meeting:

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 FPL Response to NRG RAI No. HC-7-a L-2018-169 Attachment 1 Page 2 of 5 A. The association of McGregor Smith and the cottage (e.g., use of the cottage by McGregor Smith and lands as a communal retreat).

Clarify if the use of the cottage by McGregor Smith was during construction of Units 1, 2, 3, or 4. Include the age of the cottage in the response.

B. The reason that FPL sought landmark status with Miami-Dade County for the McGregor Smith Cottage (e.g., tax credit status and building code accommodations, age of the cottage, association with a significant figure). C. Provide a copy of the McGregor Smith Cottage Preservation Project report, if available.

D. Regarding the Boy Scout structures, provide a basis as to why the three structures do not appear to meet the criteria for listing in the National Register of Historic Places and how this determination was made. Include the age of the Boy Scout structures in the response.

2. To support NRG compliance with 36 CFR 800.4(c), provide any information you have (such as history, current and past use of the structures) regarding the potential eligibility of the three Boy Scout structures and the McGregor Smith Cottage for listing in the NRHP. FPL Response:

The Boy Scout structures and the McGregor Smith Cottage will not be impacted by activities identified in the SLRA, regardless of historic designation status. The cottage and the Boy Scout structures are located within the owner-controlled area. The cottage is further located within the fenced and restricted portion of PTN and cannot be accessed without a security clearance.

This controls public access to the cottage. In response to Part 1: . A. Based on the Coastal Archaeology

& History Research, Inc. and Historic Preservation Solutions, L.L.C. report on the cultural context of the McGregor Smith Cottage, the cottage was constructed to "provide living quarters and a work space for a full-time Florida board of Conservation Ranger (Enclosure 1, page 12). There are no available records documenting McGregor Smith's association with the cottage. The building plans for the cottage were approved by the Miami-Dade County Building Department in August of 1965. Available documents do not explicitly state when the cottage was constructed, but it is assumed to have been completed in 1965 or 1966 (Enclosure 1 , page 11), which would have the cottage constructed and present during the construction of PTN Units 3 and 4. Past FPL employees have reported that some meetings held at the cottage occurred during and were related to the construction of Units 3 and 4 and were led by McGregor Smith. Additionally, past employees reported that the cottage had been used as a communal retreat.

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 FPL Response to NRG RAI No. HC-7-a L-2018-169 Attachment 1 Page 3 of 5 Current employees remember the cottage being used as a construction office and fish camp during the 1980s. During the 1990s the cottage was renovated to make it a habitable residence and it was used as temporary housing for senior FPL staff and for FPL meetings and team-building events. Due to difficult access, maintenance of the cottage has been minimal since the late 1990s. B. FPL explored the possibility of local landmark status with Miami-Dade County for McGregor Smith Cottage for the purpose of utilizing flexibility in the application of the South Florida Building Code (building officials have discretion in applying the South Florida Building Code to properties that have been designated local historic landmarks) and preservation funding (Enclosure 2; page 2). The purpose in exploring local landmark status was to determine the feasibility of moving the McGregor Smith Cottage to a different location that was in an area that was accessible to the public. The Miami-Dade County Office of Historic Preservation indicated that the McGregor Smith Cottage is not of "exceptional significance" but that it "might qualify" due to the association with McGregor Smith after it has reached the 50 years old threshold (Enclosure 2). The Miami-Dade County Office of Historic Preservation indicated that based on the information provided by FPL, the McGregor Smith Cottage was built in 1968 (Enclosure 2). However, Enclosure 1 suggests that the McGregor Smith Cottage was constructed in 1965 or 1966 (Enclosure 1, page 2). FPL did not proceed with relocating the McGregor Smith Cottage and the application for county historic designation was not prepared.

As noted in Enclosure 1 (page 7), the initial phase of Coastal Archaeology

& History Research, Inc. and Historic Preservation Solutions, L.L.C.'s preliminary feasibility study, included a proposal establishing the scope and costs associated with applying for historic designation, relocation, stabilization, rehabilitation, and interpretation of the cottage. The proposal, which is titled "McGregor Smith Cottage Preservation Project: Relocation, Rehabilitation, Historic Designation

& Interpretation," details activities associated with potential relocation of the McGregor Smith Cottage. C. Enclosure 1 provides an analysis of the historical context of the McGregor Smith Cottage. The requested document, "McGregor Smith Cottage Preservation Project," is not provided because it is a proposal document and does not provide the historical context. D. The Boy Scout camp, based on information from current FPL staff and desktop searches, was constructed in 1962-1963 and included three bunk houses (structures), a totem pole, and a "lookout hill," as well as some landscaping.

The camp was no longer used after the cooling canals were completed in the early 1970s. The three bunk houses have been converted to storage buildings and . have been subjected to maintenance and repair, diminishing their integrity relative to NRHP eligibility.

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 FPL Response to NRC RAI No. HC-7-a L-2018-169 Attachment 1 Page 4 of 5 The National Register Criteria were evaluated as follows: a. That are associated with events that have made a significant contribution to the broad patterns of our history; or Based on discussions with FPL environmental staff and internet-based desktop searches, there are no events associated with the Boy Scout camp structures that have made a significant contribution to the broad patterns of our history. There is no information to suggest that the structures associated with the Boy Scout camp were any different than other camp structures associated with the Boy Scouts of America across the region and country. b. That are associated with the lives of significant persons in our past; or There is no documentation known by FPL staff or from an internet-based desktop assessment that the Boy Scout camp structures are associated with significant persons in our past. Despite the lack of documentation, there is a strong probability that the Boy Scout camp structures are associated with McGregor Smith due to his association with PTN, the Boy Scouts of America, and environmental conservation.

Even though McGregor Smith is likely associated with the Boy Scout camp structures, the lack of information on the degree and kind of association, and the lack of overall documentation of the association, suggests the Boy Scout camp structures are not eligible for listing based 6n Criteria B. c. That embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or As described in the RAI Set 1 HC-7 response, FPL staff believe the Boy Scout camp structures lack distinctive characteristics and do not possess high artistic value or individual distinction (FPL 2018). They were constructed in a common vernacular style without elaboration.

d. That have yielded or may be likely to yield, information important in history or prehistory.

The Boy Scout camp structures have not yielded important information in history. Due to lack of distinctive characteristics, loss of integrity from maintenance and repair, and lack of association with events and individuals important to history, the Boy Scout camp structures are not likely to yield information important to history. The Boy Scout camp structures, as detailed above, do not appear to meet any of the criteria to be listed on the NRHP.

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 FPL Response to NRC RAI No. HC-7-a L-2018-169 Attachment 1 Page 5 of 5 In response to Part 2: In January of 2018, FPL consulted with the Florida State Historic Preservation Office (Division of Historical Resources) regarding the application to renew the operating license for PTN Units 3 and 4. In a letter dated April 25, 2018, the State Historic Preservation Office concurred that based on the lack of ground-disturbing activities, license renewal is unlikely to affect historic properties at PTN.

Dear Mr. Bertelson:

Let me start by thanking you again for the wonderful hospitality shown by you and your staff, and for the amazing tour of your facility.

The work you perform there within the Wildlife Conservation Area is so valuable to our community; it was especially amazing to have had the opportunity to see your administration of the American crocodile tracking and evaluation program. On August 8, 2012, I visited the Turkey Point Power Plant to evaluate the potential of the McGregor Smith Ranger House as a historic site. I observed a one-story wood frame elevated structure that was supported underneath by large cylindrical wooden posts. Thick support beams are possibly Dade County pine. The ground floor space is enclosed with screens, as is the second level wrap-around porch. The second floor living space, which includes a living/dining area, a bedroom (that has been converted into a conference room) and a bathroom, is accessed by a wooden exterior staircase.

• , The structure was built circa 1968 for the purposes of housing a full-time Florida Board of Conservation ranger. It is named after McGregor Smith, one of Florida Power and Light's first presidents (from 1939-1954) and who later served as Chief Executive Officer. The building had been used more recently as an employee retreat for business meetings and workshops, but has been sitting vacant and unused for the past couple of years. Your company has expressed an interest in ascertaining whether or not the property would qualify for historic designation, anp if it did, what are the benefits that would result from such distinction?

• Is the Building Eligible for Designation?

To be eligible for designation, a building must qualify under at least one of the criteria as spelled. out in the Historic Preservation Ordinance of Miami-Dade County Code (Chapter 16-A.) These.

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 -------------*----~-

FPL Response to NRG RAJ No. HC-7-a L-2018-169 Attachment 1 Enclosure 2 Page 3 of 4 criteria include architectural significance, associations with significant persons, associations with a significant event, or the potential to yield important information (archaeological significance).

And generally, the building should be at least 50 years of age to even be considered, unless the property is of exceptional significance.

Building plans provided to me by your staff indicate that the ranger house was built in 1968, making it 44 years old. This building might qualify for designation because of its association with McGregor Smith, who was an important figure in the history of the Florida Power and Light Company, but because the building isn't of exceptional significance, and because it is less than 50 years old, it does not qualify for a few more years. Benefits of Designation Besides the obvious benefit of protecting a resource for future generations to enjoy, buildings that have been designation as historic also become eligible for any preservation funding that may be available through the County. Additionally, building officials have discretion when reviewing projects involving historic buildings and have flexibility when it comes to applying the South Florida Building Code (though life/safety requirements are always adhered to.) Designated buildings also are eligible for Historic Preservation Ad Vaforem tax exemptions, which give owners a 100% exemption of any additional taxes that would be incurred through restoration efforts. Buildings that have been historically designated are required . to go through a Historic Preservation review before any building permit may be pulled for work, however most HP reviews are done administratively by the County staff and can be completed in one or two days. Our office only reviews work that is being proposed to the exterior of a building.

Generally, the :> interior of any building is not regulated by our code (unless the interiors were specifically designated, as they were for the mansion at Vizcaya Museum and Gardens.)

Potential to Move the Structure The McGregor Smith Ranger House is wood frame construction and not very large. It would be a relatively easy structure to move. However, having seen the proposed site where this building could be moved to, I think it would be extremely cost prohibitive because of the environmental and accessibility issues found bet'4een the current site and the proposed site. Conclusion The McGregor Smith Ranger House played a significant role in the early history of the FPL power plant at Turkey Point and is worthy of saving for future staff use and as a vestige of the flurry of activity that once took place in and around the power plant during the 1960s.

FPL's supporting response to NRG RAI No. WR-2, included in L-2018-136 Attachment 43, Enclosure 20 (ADAMS Accession No. ML 18247 A507) indicates that "Marine" wells SW-1, SW-2, and PW-1 located on the Turkey Point peninsula have been in use as recently as August 2017, presumably to support cooling canal system freshening.

While the Environmental Report states that the wells were installed in 2015 and produce saline water, little additional information is included on the three wells. Other available information indicates that at least one of the wells, PW-1, was constructed to support aquifer performance testing in 2009. In order to assess the environmental impacts of these wells, the staff needs additional information and clarification.

Specifically, the NRG staff requests additional information on the construction of these wells including:

Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 FPL Response to NRC RAI No. WR-2-a L-2018-169 Attachment 2 Page 2 of 3 verification of when each well was installed or converted for production purposes, well diameter, casing depth and type, total depth, open hole or screening interval (as applicable), and installed pump capacity.

FPL Response:

Marine wells PW-1, SW-1, and SW-2 are depicted on ER Figure 3.6-11 and discussed in ER Sections 3.6.3.2, 3.6.3.2.1, and 4.5.3.4. The information provided for the marine wells is the same type as provided for the other production wells (i.e., the well's location, aquifer, use, year placed into service, and production volume). ER Sections 3.6.3.2 and 3.6.3.2.1 include the wells' aquifer, use, and year installed.

ER Section 4.5.3.4 provides the wells' (identified as the seawater wells) combined capacity.

The marine wells do not require a consumptive use permit and their use to supply groundwater to the CCS is limited to "extraordinary circumstances" (Consent Agreement Paragraph 17.a.2) or an "upset recovery" (Section 4.3 of the Thermal Efficiency Plan). Due to potential adverse impact to the measurement of the plant's ultimate heat sink temperature and its input into technical specification compliance, the maximum supplementary flow in the intake area (discharge location of the marine wells) is operationally limited as follows:

• Total flow from SW-1, SW-2, PW-1, must be less than or equal to 41,600 gpm (59.9 MGD) when both Units 3 & 4 are in power operation.

• Total flow from SW-1, SW-2, PW-1, must be less than or equal to 23,400 gpm (33.7 MGD) when only Unit 3 or Unit 4 is in power operation.

The marine wells are intended only for "extraordinary circumstances" or "upset recovery" to come into, or remain, compliant with regulatory requirements.

In 2016/2017, as a result of previous hyper-saline conditions in the CCS and a drier than normal dry season (November

-May), the wells were used March -August in 2017. The marine wells were employed to stabilize salinity in the system until significant rainfall returned in August 2017. The activity was necessary to assist in meeting an average annual salinity target of 34 PSU by November 2020, as required by the FPL -FDEP Consent Order of June 20, 2016. Marine Well PW-1 The construction and testing for marine well PW-1 are detailed in the report Turkey Point Exploration Drilling and Test Program. The well construction diagram for PW-1 is presented in the reference as PDF page 100 of 351 (FPL 2009). As detailed in the above-referenced report, marine well PW-1 was originally drilled in January 2009 as a test production well for evaluation of the use of radial collector wells as a source of cooling water for the proposed Turkey Point Units 6 and 7 (FPL 2009, PDF page 91 of 351 ); however, following the completion of testing in 2009, all pumping equipment was removed.

Marine well PW-1 is equipped with a single stage vertical turbine pump capable of pumping 7,000 gallons per minute (gpm) at an installed depth of 40 feet. The data sheet for the pump installed in marine well PW-1 is provided in Enclosure

1. Marine Wells SW-1 and SW-2 A general construction diagram, well construction details, step drawdown test, water quality results, and lithologic logs for marine wells SW-1 and SW-2 are provided in Enclosure

2. As detailed in Enclosure 2, marine wells SW-1 and SW-2 were installed in early 2015 with the current pump and piping arrangement.

Marine wells SW-1 and SW-2 are equipped with three stage axial flow pumps capable of pumping 12,500 gpm each at an installed depth of 75 feet. Marine well SW-1 is completed with an open borehole between 23 feet and 56 feet below land surface (bis). Marine well SW-2 is competed with an open borehole between 24 feet and 55 feet bis. Therefore, the pumps are installed at depths shallower than 75 feet bis. Based on the pump performance curve, the installed pumps are capable of pumping 15,000 gpm each at 45 feet bis. The data sheet for the pumps installed in marine wells SW-1 and SW-2 is provided in Enclosure
