摘要

A landmark agreement between the USEPA and the State of Florida and the Tampa Electric Company (TEC) featured substantial reductions in SO2, NOx, and PM emissions from two coal-fired power plants in Tampa, Hillsborough County, FL, The TEC committed to re-powering the FJ Gannon power plant from coal to natural gas, re-naming the plant to the Bayside power plant; to adding SO2 scrubbers on two older boiler units at their Big Bend power plant; and to the installation of NOx controls on the Big Bend power plant, Between 1997 and 2005, an annual average decrease of 10 jag m" in ambient air SO2 concentrations at an urban monitoring site in Hillsborough County, Florida, accompanied the removal by TEC of 140,000 metric tons of SO2 from the emissions inventory. Over this period, the observed change in annual average NOx.
