PA Rule Targets Smokestack Pollution In July 2011 the U.S. EPA finalized the CrossState Air Pollution Rule to reduce SO2 and NOX emissions from power plants using available emissions control technologies. SO2 and NOX contribute to ground-level ozone and fine particle pollution and often cross state lines, ending up far from their provenance. The rule is projected to achieve up to $280 billion in annual health benefits by preventing avoidable illnesses, sick days at work, and premature deaths. Within three years the rule is expected to help reduce SO2 emissions by 73% and NOX emissions by 54% over 2005 levels.
