After a section 126 petition is filed, EPA has 60 days to respond to the petition. If EPA determines action is necessary, the polluting state must address the emissions in their State Implementation Plan (SIP). Otherwise, EPA will issue a Federal Implementation Plan (FIP) that assigns emissions limits.

Jan. 2, 2018 Delaware notifies EPA that it intends to sue EPA over its failure to address Delaware’s four section 126 petitions.
March 12, 2018 New York submits a section 126 petition requesting that EPA make a finding that emissions from sources in nine states (Illinois, Indiana, Kentucky, Maryland, Michigan, Ohio, Pennsylvania, Virginia and West Virginia) significantly contribute to nonattainment and interfere with maintenance of the 2008 and 2015 ozone air quality standards in Chautauqua County and the New York Metropolitan Area in violation of the Clean Air Act.
April 9, 2018 EPA issues a Notice of Final action rejecting Connecticut’s Brunner coal plant petition, saying it is “denying the petition based on the conclusion that Connecticut has not demonstrated and the EPA has not determined that the Brunner Island facility emits or would emit pollution in violation of the good neighbor provision with respect to the 2008 ozone NAAQS.” EPA had issued a proposed rejection in February.
May 22, 2018 The District Court for the District of Connecticut rules that EPA failed to justify its request for another year-long extension and grants Connecticut’s motion for summary judgment. The court requires EPA to hold a public hearing on a proposed decision in 30 days, and take final action on Connecticut’s petition in 60 days. Connecticut v. Pruitt et al., No. 3:17-cv-00796.
Aug. 31, 2018 EPA releases a memo to its regional offices with guidance on setting pollution thresholds for ozone levels in State Implementation Plans. The memo states that it may be appropriate to allocate a higher amount of ozone pollution to upwind states when evaluating downwind states’ SIPs. Specifically, the memo suggests using a 1-part-per-billion (ppb) contribution, which is higher than the 1 percent of the NAAQS threshold (0.70 ppb) set under the Obama administration in 2015. This change allows upwind states to contribute more ozone pollution to downwind states.
Oct. 5, 2018 EPA finalizes its denial of Delaware and Maryland’s section 126 petitions.
Oct. 12, 2018 Maryland files a petition for review in the DC Circuit of EPA’s denial of the state’s section 126 petition. Maryland v. EPA, No. 18-1285 (D.C. Cir.)
Nov. 5, 2018 Delaware files a petition for review with the DC Circuit for EPA’s denial of its four section 126 petitions. The case is later consolidated with Maryland’s case as Maryland v. EPA, No. 18-1285 (D.C. Cir.).
March 29, 2019 In their briefs, Maryland and Delaware ask the court to vacate the agency denial and to tell EPA to impose additional emissions limitations on the upwind sources. Maryland v. EPA, No. 18-1285 (D.C. Cir.).
April 12, 2019 New York sues EPA for failing to act on its section 126 petition requesting limits on emissions from 120 facilities across nine upwind states that affect its ability to comply with the 2008 and 2015 ozone NAAQS. New York alleges that EPA “has failed to hold a public hearing or take final action” on its petition filed in March 2018. New York v. EPA, No.: 1:19-cv-3287 (S.D.N.Y.).

May 19, 2020 The DC Circuit denies Delaware’s petition for review but grants, in part, Maryland’s petition. The court finds that, in light of an earlier D.C. Circuit decision, EPA too quickly dismissed Maryland’s argument that the agency should require four upwind power plants to operate non-catalytic controls. Maryland v. EPA, No. 18-1285 (D.C. Cir.).
July 14, 2020 A three-judge panel for the D.C. Circuit rules that EPA acted unlawfully by failing to provide a reasoned explanation for denying New York’s 126 petition. The court voids (vacates) EPA’s denial and sends the petition back to EPA to reconsider. The court does not give EPA a deadline by which it must issue a final decision on the petition but urges the agency to act promptly. New York v. EPA, No. 19-01231 (D.C. Cir.)
Jan. 5, 2021 The Tenth Circuit grants EPA’s request to revisit its approval of Colorado’s plan to limit excessive ozone pollution from traveling to downwind states. EPA submitted its request after the DC Circuit issued a decision in Maryland v. EPA, finding that the agency improperly estimated Maryland’s pollution contributions by using a compliance date that was too far in the future. Center for Biological Diversity v. EPA et al., No. 20-9560 (10th Cir.).
