Units 3 & 4 Uprate Implementation Water Quality Impacts

Approximate Uprate Periods

• Unit 3 was off-line to be uprated from February 26 to August 29, 2012 gradually brought back to full operating capacity by November 5, 2012.

• Unit 4 was off-line to be uprated from November 5, 2012 to April 6, 2013 gradually brought back to full operating capacity by May 27, 2013

Nitrogen TKN Increase in CCS Surface Water

Nitrogen Increase Likely linked to Apparent Algal Bloom in CCS See next 3 slides showing progressive deterioration of water clarity in the CCS
