The Clean Water Act prohibits “the discharge of any pollutant by any person,” 33 U. S. C. §1311, without a permit, into “navigable waters,” §1344. Upon determining that a violation has occurred, the Environmental Protection Agency (EPA) may either issue a compliance order or initiate a civil enforcement action. §1319(a)(3). The resulting civil penalty may not “exceed [$37,500] per day for each violation.” §1319(d). The Government contends that the amount doubles to $75,000 when the EPA prevails against a person who has been issued a compliance order but has failed to comply.
