Title 42 › Chapter CHAPTER 85— - AIR POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER I— - PROGRAMS AND ACTIVITIES › Part Part A— - Air Quality and Emission Limitations › § 7408
Publish and keep an up-to-date national list of air pollutants. The list had to be started within 30 days after December 31, 1970 and updated as needed. For any pollutant added to the list, the Administrator must write science-based air quality criteria within 12 months. Those criteria must explain the health and welfare effects, note things that change those effects (like weather), say which other pollutants can interact with it, and list any known harms. The Administrator must also give States and air agencies practical information about ways to control emissions — including costs, energy needs, emission reductions, environmental effects, available technologies, and alternative fuels or processes. The Administrator can use expert advisory committees and must review and update criteria and control information as needed. No later than six months after August 7, 1977, the Administrator had to revise NO2 criteria and discuss nitric and nitrous acids, nitrites, nitrates, nitrosamines, and other carcinogenic nitrogen products. When criteria or control info are issued, the Administrator must announce them in the Federal Register and make copies available to the public. 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 many transportation control measures (for example: better transit, high‑occupancy lanes, employer commute programs, traffic and parking strategies, bike and pedestrian facilities, anti‑idling and cold‑start controls, flexible schedules, and voluntary removal of pre‑1980 vehicles). The guidance must assess how well measures work and their effects on transportation, the environment, energy use, and the economy. The Administrator may assess ecosystem risks from criteria pollutants and must keep a central public database of emission‑control technology, including permit‑related control information from State plans.
