| Abstract |
In 1990, Congress established the Acid Rain Program under the Clean Air Act. The principal goal for the program is to achieve reduction of 10 million tons of sulfur dioxide (SO2) and 2 million tons of nitrogen oxides (NOx), the primary components of acid rain. These pollutants, in their various forms, lead to the acidification of lakes and streams rendering some of them incapable of supporting aquatic life. In addition, they impair visibility in our national parks, create respiratory problems in people, weaken forests, and degrade monuments and buildings. These environmental and public health problems caused by acid rain have affected us for several decades. We have, however, started on the path to recovery. Through efforts made by the United States Environmental Protection Agency' (EPA's) Acid Rain Program, emissions of SO2 and NOx are declining. The centerpiece of the Acid Rain Program is a creative, market-based approach for bringing about significant, cost-effective reductions in SO2. As a result of the program and its innovative approaches, we will enjoy multiple environmental and health benefits in a cost-effective manner. |
