Deadline Passed 09/01/2018. On October 2, 2017 (The Trust Effective Date, or TED), the United States District Court approved the final Mitigation Trust Agreements, completing the settlement with automaker Volkswagen AG (VW), to resolve allegations that VW violated the Clean Air Act (CAA) by selling diesel-engine cars that produced excess emissions of oxides of nitrogen (NOx). The Mitigation Trust Agreements are designed to reduce NOx emissions from other diesel engine vehicles, thereby mitigating the effects of the VW violations. All 567 federally-recognized Tribes can apply for beneficiary status.
