Researchers Tout 'Dynamic' Approach To Ozone, SO2 Emissions Mitigation

摘要

Researchers funded by EPA grants are exploring alternative "dynamic" methods for industry and states to control ozone and sulfur dioxide (SO2) pollution by requiring pollution cuts over short time periods, including a hybrid approach that would "layer" such short-term controls with existing EPA emissions trading programs. Air regulators in the Ozone Transport Commission (OTC) of Mid-Atlantic and Northeast states at an April 12 meeting of the group in Washington, D.C., noted the problem of some power plants not operating their emissions controls and instead purchasing compliance credits for agency trading programs such as the Cross-State Air Pollution Rule (CSAPR), which is designed to reduce SO2 and ozone-forming nitrogen oxides (NOx).
