Many of the environmental statutes that govern EPA actions contain provisions that allow citizens to sue EPA when EPA fails to perform an act or duty required by the statute. Unlike provisions allowing citizens to challenge final agency actions, these citizen suit provisions usually require a potential plaintiff to first provide the EPA with "notice of intent to sue" in advance of filing the lawsuit. Not all such notices result in lawsuits being filed.
