Potential soil acidification impacts of a proposed natural gas-fired combined cycle power plant were assessed using an integrated approach coupling an atmospheric deposition model with soil acidification quantification. The deposition model was used to estimate the rates of nitrogen oxide (NOx) deposition on the air-soil boundary. The expected changes in the soil column were then predicted by utilizing mechanistic and experimental methods, and the number of years required to reach critical pH values were predicted using the two methods mentioned above under different rates of acidic deposition. The number of years predicted by the mechanistic modeling approach was lower for all soils exhibiting calcareous character.
