Connecticut, Delaware, Illinois, Maryland, Massachusetts, Michigan, New York, New Jersey and Pennsylvania
sued the Bush Administration
this week claiming they failed to adequately regulate emissions of
mercury and other pollutants at older cement plant kilns. Last
December, the
EPA announced
new limits on mercury and hydrocarbon emissions from cement kilns built
after December 2, 2005, but left weak rules in place for kilns from
before that date. The states argue that the Clean Air Act requires the
EPA to limit mercury from all kilns, not just new ones.
