The National Association of State Energy Officials (NASEO) and National Association of Clean Air Agencies (NACAA) launched the NASEO & NACAA Volkswagen Settlement Clearinghouse - an online resource of state and local governments as they develop plans and implement projects under the settlement's $2.9 billion Environmental Mitigation Trust and coordinate with Volkswagen subsidiary Electrify American and other major automakers on zero-emission vehicle infrastructure investments.

Department of Justice Submits Amended Partial Consent Decree for Volkswagen Case (September 30, 2016) 

The U.S. Department of Justice (DOJ) has submitted for court approval an amended Partial Consent Decree related to Volkswagen’s alleged illegal use of emission control "defeat devices" on nearly 500,000 2.0-liter diesel vehicles of Model Years 2009 through 2015. Under the proposed settlements, VW agreed, among other things, to pay $2.7 billion for a Mitigation Trust Fund to be allocated among states and tribes for pollution reduction projects. On June 28, 2016, the parties (including DOJ, EPA, the California Air Resources Board and Volkswagen) announced a proposed consent decree and requested public comment. NACAA submitted comments on the proposal on August 2, 2016.

Based on the input received from the public and further negotiations among the parties, revisions to the partial consent decree were agreed upon and have been submitted to the U.S. District Court for the Northern District of California for final approval (U.S. v. Volkswagen AG, et al, Case No. 3:16-cv-00295). The revisions are not extensive – largely limited to Appendix D of the proposed consent decree – and are highlighted in a red-lined version of the document. Among the changes are allowing beneficiaries (e.g., states) 90 days after being 3 deemed a beneficiary to submit a “Beneficiary Mitigation Plan” that summarizes how the funds will be used. The proposed settlement originally called for plans to be submitted within 30 days. Additionally, the amended plan allows newer engines to be eligible under the program (up to model year 2009, rather than model year 2006), provides greater flexibility with respect to the percentage of the costs of repowering and replacement that are permitted to be covered and increases the amount of administrative expenses that may be claimed from 10 percent to 15 percent of the total cost of an eligible mitigation action.

Volkswagen Clean Air Act Partial Settlement

(Washington, D.C.) - On June 28, 2016, the United States lodged with the court a settlement with automakers Volkswagen AG, Audi AG, Volkswagen Group of America, Inc., and Volkswagen Group of America Chattanooga Operations, LLC (collectively “Volkswagen”).  The settlement partially resolves allegations that Volkswagen violated the Clean Air Act (“CAA”) by the sale of approximately 500,000 model year 2009 to 2015 motor vehicles containing 2.0 liter diesel engines equipped with “defeat devices” (“CAA 2.0 liter partial settlement”).  The allegations were set forth in a complaint filed by the United States on January 4, 2016, on behalf of the EPA, alleging that these vehicles are equipped with defeat devices in the form of computer software designed to cheat on federal emissions tests.  The settlement is a partial settlement because it only addresses what Volkswagen must do to address the 2.0 liter cars on the road and the pollution from these vehicles, and does not address other aspects of the United States’ complaint. The major excess pollutant at issue in this case is oxides of nitrogen (NOx), and is a serious health concern.

EPA Reports to Congress on Benefits of DERA Program (March 23, 2016)

EPA published its Third Report to Congress: Highlights from the Diesel Emission Reduction Program (DERA). In the report, EPA provides final results from grants awarded in fiscal years (FY) 2009 through 2011 and estimated results from grants funded in FYs 2011 through 2013. EPA reports that, overall, DERA grants have improved air quality and public health; served disproportionately affected communities; reduced climate impacts and improved fuel savings; focused on goods movement and the supply chain; generated economic and environmental activity; and responded to popular demand. In addition to preventing up to 1,700 premature deaths, the program has reduced 4,836,100 tons of carbon dioxide, 312,500 tons of nitrogen oxides, 58,700 tons of carbon monoxide, 18,900 tons of hydrocarbon and 12,000 tons of particulate matter and saved 431 million gallons of fuel. Under the DERA program, $520 million in funds have been awarded and 58,000 engines have been retrofitted or replaced; the monetized health benefits reach as high as $11 billion with 81 percent of projects targeted to areas facing air quality challenges.
