2011 ANNUAL NON RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT

1.0 BACKGROUND

Appendix 8 of the Renewed Facility Operating License for the Palisades Nuclear Plant (PNP) requires the submittal of an annual environmental operating report to the Nuclear Regulatory Commission (NRC), describing the implementation of the Environmental Protection Plan (EPP) during the previous year. The reporting period is January 1,2011, through December 31,2011.

The PNP operated for 8,409 hours and produced a net total of 6,641,013 MWHe during 2011. This represents 92.4% of the net demonstrated capacity of the design electric rating of 805 MWe.

2.0 ENVIRONMENTAL IMPACT EVALUATIONS

Four engineering change documents were evaluated per Entergy Nuclear Operations, Inc. (ENO) procedure, EN-EV-115, "Environmental Reviews and Evaluations," during 2011.

Engineering Changes (EC) 26813, 26814 and 26815 were reviewed and approved for installation of gas in oil monitors for start up transformers 1-1 , 1-2 and 1-3, respectively.

EC 30739 was approved to allow re-installation of the augmented cooling system for condensate pump P-28 thrust bearing (the same temporary modification was installed in 2010 under EC 20672).

There were no changes, tests, or experiments that involved an unreviewed environmental question and no EPP changes were required.

3.0 ADDITIONAL ACTIVITIES AUTHORIZED UNDER NPDES

ENO received approval from the MDEQ on May 25, 2011 , for the reduction in monitoring of low level mercury (LLHg). The site NPDES permit was issued in November 2009, which required sampling and analysis for LLHg on a monthly basis. Approval was given to eliminate monthly sampling and sample annually.

A request and subsequent information to increase the discharge concentration of Thruguard THR404 from Outfall 001 was submitted. The request was approved by the Michigan Department of Environmental Quality (MDEQ) on August 12, 2011. Outfall 001 discharges to Lake Michigan. Thruguard THR404 is used for scale prevention in the plant cooling water system.

ENO received approval from the MDEQ on August 24,2011, for the use of wood flour as a water treatment additive (WT A) under the site national pollutant discharge elimination system (NPDES) permit. The wood flour additive is used as an aide in condenser tube plugging for leaking tubes.

4.0 UNUSUAL ENVIRONMENTAL EVENTS

The MDEQ Water Resources Division (WRD) conducted a site inspection on June 16, 2011. The purpose of the inspection was to evaluate the property for compliance with MDEQ permit 09-80-0058-P issued under Part 353, Sand Dunes Protection, of Natural Resources and Environmental Protection Act, 1994 PA 451 as amended (Part 353). The permit was issued in support of the security owner controlled area (SOCA) fence installation project. At the time of the inspection, MDEQ staff observed activities unrelated to the above permit: placing a volume of sand with mixed debris along the south side of the "A" cooling tower area, and excavation of an area for the purpose of emergency repair work. These activities are regulated under the authority of Part 353.

A review of WRD files indicated that no permits were issued for these activities, which is a violation of Part 353. The MDEQ issued a violation and order to restore on July 14, 2011. Immediate remediation was performed to the satisfaction of the MDEQ Engineer. The violations were tracked and closed under CR-PLP-2011-03487.

5.0 ENVIRONMENTAL MONITORING

Documentation of the effect of cooling tower operation on meteorological variables was required for two years following the conversion from the once­through cooling system to the cooling towers. Because the cooling towers have been in operation for 37 years, meteorological monitoring and other monitoring activities related to the cooling towers were not required during 2011. Herbicides were not applied to the transmission line exit corridor in 2011.

TruGreen and Katerberg VerHage treated other areas of the property for vegetation management during 2011. The application of herbicides is documented in Attachment 2.

6.0 NON-ROUTINE REPORTS

During 2011, no non-routine reports were generated.
