c High bias to analytical results exists due to analytical issues encountered.
However, biased value was reported.
The WQPP was developed by UT-Battelle and approved by TDEC in 2008, and initial rounds of
WQPP monitoring were conducted in 2009. The WQPP incorporated several control plans that were
required under the previous NPDES permit, including a Biological Monitoring and Abatement Plan
(BMAP), a Chlorine Control Strategy, a Storm Water Pollution Prevention Plan, a Best Management
