For the sake of health

Orlando Sentinel: Advocates for public health and the environment won an important battle last week. A federal court blocked a regulatory change that would have let operators of the dirtiest power plants evade the Clean Air Act.
But Congress needs to make sure those advocates win the war.
The regulatory change the court blocked would have let operators of power plants and other industrial facilities make modifications that would increase emissions without installing modern pollution-control equipment. The change would have undone a Clean Air Act provision.
The Bush administration had failed to get Congress to agree to such a change in the law. The court ruled the administration couldn't do so through a regulation.
For the sake of public health and the environment, Congress must set a firm deadline for old power plants and other industrial facilities to clean up.
