HIGHLIGHTS OF THE CLEAN-AIR ACT AMENDMENTS OF 1990

When President Bush put his pen to the Clean Air Act Amendments of 1990 last November, it marked the end of a decade-long battle in Congress over air pollution and acid rain. President Bush called the final clean air bill "true to the architecture and spirit" of the clean air proposal he had submitted to Congress some 18 months previously, breaking the ten-year congressional stalemate over clean air. "This legislation isn't just the centerpiece of our environmental agenda," the president said as he signed the bill. "It is simply the most significant air pollution legislation in our nation's history."
