The United States Supreme Court may soon decide a question of due process under the Clean Water Act (CWA) which has broader implications for the way EPA enforces the nation’s environmental laws. The question is whether the Fourteenth Amendment requires that a landowner be able to challenge an EPA compliance order in court before EPA seeks to enforce that order. Because other environmental statutes, such as the federal Superfund statute, also bar pre-enforcement review of EPA orders, the Supreme Court’s decision could materially affect EPA’s future enforcement strategies.
