February 1, 2010 – The Center filed a notice of intent to sue the U.S. Environmental Protection Agency for failing to determine whether five western states were complying with existing standards designed to protect the public from tiny airborne particles like black carbon (soot) and dust, and by failing to ensure that states were implementing legally required plans to meet the standards.

February 22, 2010 – The Center petitioned the EPA to set water-quality criteria for concentrations of black carbon on sea ice and glaciers under the Clean Water Act — the first petition to explicitly seek protection of water in its solid form, and the first step toward reducing black-carbon emissions from diesel engines and other sources due to their role in accelerating the loss of sea ice and glaciers.

June 22, 2011 – The Center notified the EPA of our intent to file a lawsuit against the agency for its failure to take action to reduce black carbon, a potent global warming pollutant, as we requested in our 2010 petition.
