EPA's National Vehicle and Fuel Emissions Laboratory Has Taken Steps to Mitigate Impact of Coronavirus Pandemic on Mobile Source Emission Compliance [open pdf - 1MB]
From the Document: "The U.S. Environmental Protection Agency's Office of Inspector General initiated an evaluation to determine:  How the coronavirus pandemic--that is, the SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] virus and resultant COVID-19 [coronavirus disease 2019] disease--has impacted laboratory operations and testing at the EPA's Office of Transportation and Air Quality's National Vehicle and Fuel Emissions Laboratory, or NVFEL, in Ann Arbor, Michigan.  Any resulting impacts on the OTAQ's [Office of Transportation and Air Quality] compliance programs, which are designed to minimize the potential for emissions in excess of standards or for noncompliance with regulations in heavy-duty, light-duty, and nonroad vehicles, engines, and equipment. This report addresses these objectives based on our work within the OTAQ and contains no recommendations. This report examines the EPA's activities to oversee mobile source compliance with clean air laws and regulations during the coronavirus pandemic. It highlights NVFEL's efforts to minimize the potential for noncompliance during the pandemic and the importance of returning to full testing capacity to provide the most effective oversight."
