Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER I — PROGRAMS AND ACTIVITIES › Part A — Air Quality and Emission Limitations › § 7408
The Administrator must make and keep a public list of air pollutants. The list had to be published within 30 days after December 31, 1970 and updated as needed. A pollutant gets included if its emissions may harm health or welfare, if it comes from many different sources, or if air quality rules for it were planned but not issued before December 31, 1970. For any pollutant put on the list, the Administrator must issue science-based air quality criteria within 12 months. The criteria must explain health and welfare effects, things that change those effects (like weather), other pollutants that can interact with it, and known harms. At the same time, the Administrator must give states and local agencies information on ways to control pollution, including costs, energy use, emission benefits, and environmental effects. The Administrator can set up expert advisory committees from state and local governments, industry, and universities. All criteria and control information must be announced in the Federal Register and made available to the public. The Administrator had to revise NO2 criteria within six months after August 7, 1977 and include specific nitrogen compound effects. The Administrator must also update transportation-air quality planning guidance within nine months after November 15, 1990 and provide, within one year after that date, information on transportation control measures. That guidance covers how to choose and review planning options, funding needs, public participation, and methods to reduce vehicle pollution (for example public transit, high-occupancy lanes, trip-reduction programs, bike and pedestrian facilities, limits on vehicle use, and removing old vehicles). The guidance must also include ways to protect sensitive groups, reduce pollution during episode alerts, and check if a control method raises other pollutants. It must assess each method’s effectiveness, effects on transportation services, and environmental, energy, and economic impacts. The Administrator may study ecosystem risks from criteria pollutants and must run a central clearinghouse with control-technology data, including information from state permit programs.
