Ambitious Plan To Improve Houston Air Quality Approved

"An ambitious, five-year plan to clean the air in Houston and surrounding counties that includes drastic cuts in industrial pollutants, lower speed limits and stricter vehicle exhaust testing was approved by federal regulators Monday... If successfully implemented, supporters maintain, the plan...will finally bring the region into compliance with national ozone standards -- 31 years after the federal Clean Air Act was signed into law...Skeptics and opponents of the plan doubt it will achieve its goal and are considering lawsuits to change it."
