RE: List of Documents for PNNL Gentlemen:
In the interest of efficiency, I am attaching two documents for your information (with another in a separate email) and that are germane to our audit needs request to FPL (which is duplicated below). In short, Bill Ford and I want you to be aware of our line of inquiry on these matters and relevant new information so that you can better support us in our interactions with FPL and its contractor staff. Likewise, some of this information may well be referenced during the interagency meeting.
As for the audit itself, we do not yet have a detailed audit agenda in place, so we do not yet know what FPL is planning to present to us. Hoping to have it soon!
Please advise if any of the PDFs did not come through directly and I will upload them to EARRTH directly Bo set up for us.
Bill, please elaborate as appropriate.
Rajiv and Phil, please reach back to us with any immediate questions.
Finally, I plan to set up a conference call among us the middle of next week so that we can coordinate. Let me know if there are any days that are problematic.
Thanks.
Kevin Audit Request for a Groundwater and Surface-Water Modeling Presentation In 2016, TETRA TECH finished for FPL, A Groundwater Flow and Salt Transport Model of the Biscayne Aquifer. One of the purposes of this model is to assess the efficacy of the recovery well system to retract the hypersaline plume in the Biscayne Aquifer west and north of FPL's property.
(Note this report can be found at the end of the September 25, 2017 testimony of Peter Andersen before the Florida 1 Public Service Commission located at:
http://www.psc.state.fl.us/library/filings/2017/07901-2017/07901-2017.pdf)
In 2014 TETRA TECH completed an Evaluation of Drawdown in the Upper Floridan Aquifer Due to Proposed Salinity Reduction-based Withdrawals. To reduce the salinity within the cooling canal system, water from the Upper Floridan Aquifer will be discharged into the cooling canal system. This model was used to determine potential impacts to other users of Floridan Aquifer water from the withdrawal of Floridan Aquifer groundwater.
Also in 2014, TETRA TECH also completed an Evaluation of Required Floridan Water for Salinity Reduction in the Cooling Canal System. Water and salt balance modeling of the cooling canal system was performed to assess the volume of water from the Floridan Aquifer required to reduce the salinity of cooling canal system water to seawater concentrations. Reducing the salinity in the cooling canal system is predicted to reduce the contribution from the CCS to the hypersaline plume in the Biscayne Aquifer.
(Note: These 2014 reports can be found in document filed in ADAMS accession number ML14279A555.)
These complex models are important to the prediction to future impacts by the hypersaline groundwater over the period of subsequent license of license renewal.
We would like to better understand these modeling studies and attendant projections. At the audit, we would like an on-site presentation by knowledgeable staff on these models; including any recent updates. We are interested in understanding the projections of cooling canal salinities, of impacts on Floridan Aquifer groundwater users, and of the efficacy of the planned recovery well system operation in retracting the hypersaline plume. Please allow time for questions from NRC staff and contractors.

The following document was reviewed as part of the Final Environmental Impact Statement for Turkey Point. The impact statement said it did not change our understanding of how the cooling canal operates.
However, as it focuses on the power uprate and the cause of increased salinities in the cooling canal system, it may come up again during license renewal Final Report, The Cooling Canal System at the FPL Turkey Point Power Station, May 2016, which can be accessed at http://www.miamidade.gov/mayor/library/memos-and-reports/2016/05/05.12.16-Final-Report-on-the-Cooling-Canal-Study-at-the-Florida-Power-and-Light-Turkey-Point-Power-Plant-Directive-151025.pdf
