The legal issues presented in this case will be displayed here.

This section contains the nature of the case and procedural background.

In July 1997, EPA issued final rules revising the preliminary and secondary NAAQS (national ambient air quality standards) for particulate matter (PM) and ozone. This was opposed by a number of organizations on grounds that D construed sections 108-109 of the Clean Air Act so loosely as to render them unconstitutional delegations of legislative power. The statute required the EPA to establish NAAQS at a level to protect the public health with an adequate margin of safety.
