The Clean Air Act Amendments of 1990 were a significant piece of legislation aimed at reducing air pollution in the United States. Enacted on November 15, 1990, these amendments built upon the original Clean Air Act of 1970, which was designed to regulate air pollution from stationary and mobile sources. In this article, we will delve into the key provisions of the Clean Air Act Amendments of 1990 and examine the accuracy of two statements regarding this legislation.

The Clean Air Act Amendments of 1990: A Brief History

The Clean Air Act Amendments of 1990 were a response to the growing concerns about air pollution in the United States. The amendments were designed to reduce emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM) from power plants and other industrial sources. The amendments also established new standards for mobile sources, including vehicles and engines.

Statement A: Power Plants and SO2 Pollution Allowances

The Clean Air Act Amendments of 1990 introduced a cap-and-trade system for sulfur dioxide (SO2) emissions from power plants.

The Clean Air Act Amendments of 1990 introduced a cap-and-trade system for sulfur dioxide (SO2) emissions from power plants. This system allowed power plants to buy and sell SO2 pollution allowances, which were allocated based on each plant's emissions levels. The goal of this system was to reduce SO2 emissions from power plants by 10 million tons per year by the year 2000. The cap-and-trade system was a innovative approach to reducing emissions, as it allowed power plants to choose the most cost-effective way to reduce their emissions.

Statement B: CAFE Standards for Light Trucks

The Clean Air Act Amendments of 1990 actually increased the CAFE standards for light trucks, not decreased them.

The Clean Air Act Amendments of 1990 actually increased the Corporate Average Fuel Economy (CAFE) standards for light trucks, not decreased them. The amendments required light trucks to meet a minimum fuel economy standard of 20.7 miles per gallon (mpg) by the year 1995. This was an increase from the previous standard of 18 mpg. The amendments also required passenger cars to meet a minimum fuel economy standard of 27.5 mpg by the year 1995.

Key Provisions of the Clean Air Act Amendments of 1990

The Clean Air Act Amendments of 1990 included several key provisions aimed at reducing air pollution in the United States. Some of the key provisions include:

  • Sulfur dioxide (SO2) emissions reductions: The amendments required power plants to reduce their SO2 emissions by 10 million tons per year by the year 2000.
  • Nitrogen oxides (NOx) emissions reductions: The amendments required power plants to reduce their NOx emissions by 2 million tons per year by the year 2000.
  • Particulate matter (PM) emissions reductions: The amendments required power plants to reduce their PM emissions by 2 million tons per year by the year 2000.
  • Mobile source emissions reductions: The amendments required vehicles and engines to meet new emissions standards, including a minimum fuel economy standard of 27.5 mpg for passenger cars and 20.7 mpg for light trucks.
  • Cap-and-trade system: The amendments introduced a cap-and-trade system for SO2 emissions from power plants, allowing power plants to buy and sell pollution allowances.

Conclusion

The Clean Air Act Amendments of 1990 were a significant piece of legislation aimed at reducing air pollution in the United States. The amendments introduced a cap-and-trade system for sulfur dioxide (SO2) emissions from power plants and increased the Corporate Average Fuel Economy (CAFE) standards for light trucks. The key provisions of the amendments included sulfur dioxide, nitrogen oxides, and particulate matter emissions reductions, as well as mobile source emissions reductions. The amendments were a major step forward in reducing air pollution in the United States and have had a lasting impact on the country's environmental policies.
