Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER I — PROGRAMS AND ACTIVITIES › Part A — Air Quality and Emission Limitations › § 7426
States must make rules that force big new or changed pollution sources that are covered by the federal "significant deterioration" rules or that could push pollution above national limits in another State to send written notice to any nearby States that might be affected. That notice must come at least 60 days before the State would allow construction to begin. States also had to list major existing sources that might have that kind of impact and tell nearby States who they were no later than three months after August 7, 1977. Any State or local government can ask the EPA Administrator to find that a major source or group of sources is or would be breaking the ban named in the law. After a public hearing, the Administrator must decide within 60 days. If the Administrator finds a violation, building or operating the new or changed source is not allowed, even if the State issued a permit. An existing major source must stop operating no more than three months after the finding, unless the Administrator allows more time with required limits and a schedule to reach compliance. Any extra time cannot go beyond three years, and the source could still face enforcement actions after that.
