Background

Bartow plant is decommissioning on-site detention ponds and diverting process water to cooling water intake.  Ultimately discharge to Old Tampa Bay.

Summer 2013

Not a “new” discharge.  Both atmospheric and unknown groundwater contributions.

Allocation Request

Progress Energy is requesting a surface discharge allocation of 3 tons/year

Reductions from repowering facility

Repowering of the plant (online in 2009): average atmospheric reduction of 2,726 tons NOx from 2010-2011

For every 100 tons NOx in atmospheric discharge, 0.19% is deposited to the Bay as direct nitrogen loadings (ECT, TECO)

Progress Energy reduced their direct Bay loadings by 5.18 tons from 2010-2011

Requesting concurrence from Consortium on allocating 3 tons/yr surface discharge in 

Old Tampa Bay for Progress Energy
