The paper summarizes the various acid deposition bills introduced in the U.S. Congress during the past 2 years and discusses emission sources. A rapidly emerging technology called Limestone Injection/Multistage Burners (LIMB), which has the potential for simultaneous SO/sub 2/ and NOx control, is described including background, current status, and plans. Finally, the possible implications of legislative alternatives and their effect on control technology requirements are presented. Acid rain continues to be a major environmental issue, and the importance of various acid precursor sources is still under debate. More than 15 bills that were pending in Congress required large sources of SO/sub 2/ and/or NOx (two major pollutants resulting from the combustion of fuels) to reduce their emissions. Coal-fired utility boilers account for about 70% of the SO/sub 2/ and 20-25% of the NOx emissions in the U.S. With this scenario, the timeliness and importance of low-cost control options applicable to these sources are evident. The breadth and depth of the research and development activities underway, both foreign and domestic, testify to the widespread interest in the potential benefits of these control technologies and the optimistic expectations for success in the on-going programs.
