The Maine Department of Transportation has submitted a plan to reduce nitrous oxide as part of an Environmental Protection Agency judgment against Volkswagen (VW). Wilmington Trust, the VW settlement trustee, reviewed the plan as satisfactory last week. The plan offers to cover up to 75 percent of the costs to convert non-governmental fleets to more environmentally friendly fuel supplies, and covers 100 percent of costs on governmental fleets. Funds are also allocated for electric vehicle service equipment, such as charging stations, to support adoption of electric vehicles. Maine’s allocation totals just over $21 million, determined by the number of state-registered vehicles identified as having defeat devices. State settlements resolve VW’s Clean Air Act violations, resulting from nationwide sales of approximately 590,000 model years 2009 to 2016 diesel motor vehicles equipped with defeat devices such as computer software designed to cheat on federal emissions tests.
