Clean Air In the News

Environmental groups sued the Shell Oil Company and several of its
affiliates, claiming that the oil giant has for years released
pollutants from its suburban Houston refinery that are well above state
and federal limits. In the federal lawsuit, the Sierra Club
and Environment Texas claim that the excess air pollutants, including
the toxic chemicals benzene and 1,3-butadiene, are a violation of the
federal Clean Air Act.
