Title: Impacts of Title IV in Maryland

The Maryland Department of Natural Resources` Power Plant Research Program has evaluated the environmental effects of acid deposition on Maryland`s air, land, water (especially the Chesapeake Bay), and human resources since the mid-1980`s. Title IV of the Clean Air Act Amendments of 1990 (CAAA90) has focused much attention on the mandated reductions of nitrogen oxides (NO{sub x}) and sulfur dioxide (SO{sub 2}) to control acid deposition. Baseline data on acidic deposition and air emissions/pollution control for NO{sub x} and SO{sub 2} acquired through PPRP studies have proved useful in evaluating the impacts of Title IV on Maryland power plants and resources. Three example programs are discussed: The first is an evaluation of SO{sub 2} emissions on ecosystems through the use of critical loads--the amount of acid rain that an ecosystem can tolerate without continuing to acidify. Results support the use of broadly based emissions trading scenarios: The second study is an evaluation of the potential for reducing nitrate loading in the Chesapeake Bay by reducing NO{sub x} emissions. Results indicate substantial NO{sub x} emission reductions could offer significant reductions in nitrate deposition to the Bay: The final study is a review of the impacts of Title IV on the Marylandmore » coal industry and the prospects for coal cleaning and advanced combustion technologies. Current results indicate that Maryland coal will meet Phase 2 SO{sub 2} emission standards using advanced combustion techniques, such as fluidized bed technologies, but that additional emissions controls, such as a scrubber would be required in a conventional boiler.« less
