Title: Complex Unintended Consequences Obscure the Path Forward for Air Pollution Control

A small Ohio town no longer exists thanks to the unintended consequences of air pollution control. A nearby power plant spent hundreds of millions of dollars to reduce Nox. The catalyst not only reduced the Nox it converted SO2 to sulfuric acid. Within a few days, the acid deposition did such great damage to the buildings in the town that the utility agreed to buy the complete town and pay for relocations. In the ensuing decade, catalyst suppliers have redesigned their product to eliminate this problem. New mercury regulations have such low emission limits that the instrument just to measure gaseous mercury can cost hundreds of thousands of dollars. Prior to issuing the regulation, EPA tested a number of stacks and found that all the mercury existed in gaseous form. Therefore, the regulations only required measurement of gaseous mercury. In response to the regulation requirements, power plants, cement plants and waste-to-energy plants embraced a two-step solution
