Document Summary
No -----> attainment in aqcr, are any 6 cps exceeding the naaqs ------> yes. Caa -> a partnership between the federal + state governments congress created federal government establishes the base and the states are tasked with implementing. Congress did 2 things: created nationally uniform standards for quality air, tech-based standards for individual polluters" emissions. Factors considered with tech: how new the company is and how much money they have the original approach in 1967 -> congress expected a region-by-region passed an amendment. 6 criteria pollutants: particular matter, sulfur dioxide, ozone, nitrogen oxide, carbon monoxide, hydrocarbons criteria pollutants -> compounds, two elements combine, not toxic in typical concentrations, but they are undesirable. Mass v. epa -> state was demanding to have standing. Epa is an agency, it will have a major in uence on how caa is implemented initially, epa decided not worth their time to regulate co2 and greenhouse gases.
