This may help.

To answer the NRC question on what we are doing long-term for the elevated flooding, I would recommend including all the enhancements FCS has included that is beyond our design basis:

1) Aqua Dams around PA and major buildings
2) Earthen berm in switchyard to protect off site power
3) Barriers around Security building
4) Additional pumps for dewatering areas
5) Redirecting roof drains exterior to berms
6) Elevating 13.8 KV on the site to support continued power to buildings and pumps
7) Brought-in a Temporary 480 VAC DG with 480 VAC to 4160 Volt AC step up transformer
8) Brought in 2 tankers for addition 15,000 gallons of additional DG fuel
9) Elevated scaffolding for access to facilities (vice having to rely on boats)
10) Monitoring the conditions and make repairs as issues develop Erick Matzke Fort Calhoun Station FC-2-4 402-533-6855 NAVY This e-mail contains Omaha Public Power District's confidentiala d roprietary information and is for use only by the in nde p Unless ex lic s d otherwi ,is e-mail is contract offer, amendment, nor acceptance. f you are not t ended recipient you are notified that disclosing, copying, distributing or taking any action in reliance on the contents of this information is strictly prohibited.
