The agreement resolves EPA allegations that Dow Corning failed to meet several conditions that restrict emissions of volatile organic compounds and particulate matter in the manner required by its state operating permit and state regulations.
Volatile organic compounds contribute to the formation of ground-level ozone or smog, the agency said. Smog can cause a variety of respiratory problems, including coughing, wheezing, shortness of breath and chest pain.
Inhaling high concentrations of particulates can affect children, the elderly and people with heart and lung diseases the most.
Dow Corning, which is a venture of Dow Chemical Co. and Corning Inc., was not available for comment.
