House Passes H.R. 4775, the Ozone Standards Implementation Act of 2016

 

The legislation allows states to pursue cost-effective and practical implementation of EPA’s ozone standards.   Under the Clean Air Act’s NAAQS program, the EPA sets standards for criteria pollutants, including ground-level ozone. EPA initially established ozone standards in 1971, and subsequently revised them in 1979, 1997, and 2008. Unfortunately, EPA did not publish implementing regulations for the 2008 standards until March 2015, and states are just beginning to implement those standards. Because EPA then revised these standards in October 2015, states now face the prospect of simultaneously implementing two ozone standards.

Further, states are increasingly confronting other challenges under the statutory construct of the NAAQS implementation program. These challenges range from the agency’s failure to issue timely implementation regulations and guidance when standards are revised, to specific issues relating to foreign emissions or exceptional events, provisions in the statute that have been interpreted to require states to pursue measures that may not be technologically or economically feasible, and the current statutory requirement that EPA review all NAAQS no later than every 5 years.

United States Files Complaint Against Volkswagen, Audi and Porsche for Alleged Clean Air Act Violations

The U.S. Department of Justice, on behalf of the U.S. Environmental Protection Agency, today filed a civil complaint in federal court in Detroit, Michigan against Volkswagen AG, Audi AG, Volkswagen Group of America, Inc., Volkswagen Group of America Chattanooga Operations, LLC, Porsche AG, and Porsche Cars North America, Inc. (collectively referred to as Volkswagen). The complaint alleges that nearly 600,000 diesel engine vehicles had illegal defeat devices installed that impair their emission control systems and cause emissions to exceed EPA’s standards, resulting in harmful air pollution. The complaint further alleges that Volkswagen violated the Clean Air Act by selling, introducing into commerce, or importing into the United States motor vehicles that are designed differently from what Volkswagen had stated in applications for certification to EPA and the California Air Resources Board (CARB).

EPA Issues Final Rule on Ozone Standards

The U.S. Environmental Protection Agency (EPA) has strengthened the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb) from 75 ppb. The Clean Air Act provides states with time to meet the standards. Depending on the severity of their ozone situation, areas would have until between 2020 and 2037 to meet the standards. See EPA’s full release here.

EPA Continues to Investigate Clean Air Act Violation

WASHINGTON – Today the U.S. Environmental Protection Agency (EPA) released a letter sent to vehicle manufacturers notifying them that the agency is adding to its confirmatory testing additional evaluations designed to look for potential defeat devices.

View the letter here:  http://www3.epa.gov/otaq/cert/violations.htm

Last Friday, EPA sent a Notice of Violation of the Clean Air Act to Volkswagen AG, Audi AG, and Volkswagen Group of America, Inc. alleging that four-cylinder Volkswagen and Audi diesel cars from model years 2009-2015 include software that circumvents EPA emissions standards.

These cars contain software that turns off emissions controls when driving normally, and turns them on when the car is undergoing an emission test.  Known as a “defeat device,” this design feature results in the cars emitting up to 40 times the amount of NOx emissions that the standards allow.  NOx standards are in place to ensure public health is protected.

EPA’s notice of violation, along with an In-Use Compliance Letter that the California Air Resources Board issued, provide information and details relating to the VW violations:

EPA, California Notify Volkswagen of Clean Air Act Violations

Carmaker allegedly used software that circumvents emissions testing for certain air pollutants

Today, EPA is issuing a notice of violation (NOV) of the Clean Air Act (CAA) to Volkswagen AG, Audi AG, and Volkswagen Group of America, Inc. (collectively referred to as Volkswagen). The NOV alleges that four-cylinder Volkswagen and Audi diesel cars from model years 2009-2015 include software that circumvents EPA emissions standards for certain air pollutants. California is separately issuing an In-Use Compliance letter to Volkswagen, and EPA and the California Air Resources Board (CARB) have both initiated investigations based on Volkswagen’s alleged actions.
