Introduction to Control of Gaseous Pollutants Under the auspices of the EPA Center for Environmental Research Information inconjunction with the EPA Control Technology Center, a handbook for design ofhazardous air pollution control equipment was published in 1986.[r]

It is evident from the European and U.S. experiences that command-and-control and economic regulation are two strategies that both do the job of reducing air pollution. Europe makes use of economic regulation at the energy level, and command-and-control at the emissions l[r]
