Complaints and Petitions for Review

Many of the environmental statutes contain provisions that allow citizens to sue EPA when EPA allegedly fails to perform an act or mandatory duty required by the statute. Citizens may also file petitions for review in courts to challenge actions taken by EPA. The table below contains complaints and petitions for review received by EPA. Complaints are added as they are received. Many complaints include multiple parties or petitioners. Please use the search feature to search for complaints filed by a specific group or individual. Note that all links in the table below open in a new tab.

Administrative petitions for rulemaking and Guidance petitions are located on EPA’s Petitions Page.

OGC manages litigation for the Agency in over 380 environmental matters. View the docket of cases.

OGC also manages the Agency’s legal obligations in the following list of consent decrees and settlement agreements involving environmental matters. The list contains future deadlines for EPA action, and brief descriptions of those deadlines. View the table of cases.
