Title 42 › Chapter CHAPTER 85— - AIR POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER III— - GENERAL PROVISIONS › § 7604

Summary

People can file a lawsuit to enforce clean-air rules. They may sue any person (including the United States or other government bodies when allowed by the Constitution) who is said to be violating or repeatedly violating an emission rule or an order about that rule. They may sue the EPA Administrator if the Administrator fails to do a nondiscretionary duty required by the law. They may also sue anyone who plans or builds a new or changed major pollution source without a required permit under part C or part D of subchapter I, or who violates a condition of such a permit. Before suing for a violation, the person must give 60 days’ written notice to the EPA Administrator, the State where the violation happens, and the alleged violator. If the EPA or a State is already diligently suing to fix the same violation, a private suit cannot start, though a private party may still join that federal suit. Suits about a particular stationary source must be filed where that source is located. The EPA may join the case. The plaintiff must send the complaint to the U.S. Attorney General and the Administrator. No consent judgment can be entered until 45 days after those officials get a copy. Courts can order losing parties to pay legal costs, including attorney and expert fees, and may require a bond for temporary orders. This law does not take away other enforcement rights. “Emission standard or limitation” covers things like compliance schedules, emission limits, fuel controls, permit conditions, and specific provisions such as sections 7411, 7412, 7419, 7491, 7545(e) and (f), and subchapter VI. Civil penalties normally go into a special Treasury fund for EPA use, but a court may instead order up to $100,000 to be spent on mitigation projects that improve public health or the environment after consulting the Administrator.
