33 USC 1365 - Citizen suits
Sec. 1365. Citizen suits(a)
Except as provided in subsection (b) of this section and section 1319 (g)(6) of this title, any citizen may commence a civil action on his own behalf—
(1) against any person (including (i) the United States, and (ii) any other governmental instrumentality or agency to the extent permitted by the eleventh amendment to the Constitution) who is alleged to be in violation of (A) an effluent standard or limitation under this chapter or (B) an order issued by the Administrator or a State with respect to such a standard or limitation, or
(2) against the Administrator where there is alleged a failure of the Administrator to perform any act or duty under this chapter which is not discretionary with the Administrator.
The district courts shall have jurisdiction, without regard to the amount in controversy or the citizenship of the parties, to enforce such an effluent standard or limitation, or such an order, or to order the Administrator to perform such act or duty, as the case may be, and to apply any appropriate civil penalties under section 1319 (d) of this title.
No action may be commenced—
(1) under subsection (a)(1) of this section—
(A) prior to sixty days after the plaintiff has given notice of the alleged violation
(i) to the Administrator,
(ii) to the State in which the alleged violation occurs, and
(iii) to any alleged violator of the standard, limitation, or order, or
(B) if the Administrator or State has commenced and is diligently prosecuting a civil or criminal action in a court of the United States, or a State to require compliance with the standard, limitation, or order, but in any such action in a court of the United States any citizen may intervene as a matter of right.
(2) under subsection (a)(2) of this section prior to sixty days after the plaintiff has given notice of such action to the Administrator,
except that such action may be brought immediately after such notification in the case of an action under this section respecting a violation of sections 1316 and 1317 (a) of this title. Notice under this subsection shall be given in such manner as the Administrator shall prescribe by regulation.
Venue; intervention by Administrator; United States interests protected
(1) Any action respecting a violation by a discharge source of an effluent standard or limitation or an order respecting such standard or limitation may be brought under this section only in the judicial district in which such source is located.
(2) In such action under this section, the Administrator, if not a party, may intervene as a matter of right.
Protection of interests of united states.—
Whenever any action is brought under this section in a court of the United States, the plaintiff shall serve a copy of the complaint on the Attorney General and the Administrator. No consent judgment shall be entered in an action in which the United States is not a party prior to 45 days following the receipt of a copy of the proposed consent judgment by the Attorney General and the Administrator.
The court, in issuing any final order in any action brought pursuant to this section, may award costs of litigation (including reasonable attorney and expert witness fees) to any prevailing or substantially prevailing party, whenever the court determines such award is appropriate. The court may, if a temporary restraining order or preliminary injunction is sought, require the filing of a bond or equivalent security in accordance with the Federal Rules of Civil Procedure.
Statutory or common law rights not restricted
Nothing in this section shall restrict any right which any person (or class of persons) may have under any statute or common law to seek enforcement of any effluent standard or limitation or to seek any other relief (including relief against the Administrator or a State agency).

Civil action by State Governors
A Governor of a State may commence a civil action under subsection (a) of this section, without regard to the limitations of subsection (b) of this section, against the Administrator where there is alleged a failure of the Administrator to enforce an effluent standard or limitation under this chapter the violation of which is occurring in another State and is causing an adverse effect on the public health or welfare in his State, or is causing a violation of any water quality requirement in his State.
