DENVER (AP) - A complaint filed Tuesday in U.S. District Court in Denver accuses EnCana of misdemeanor violations of the Migratory Bird Treaty Act in the deaths of about 15 birds in western Colorado between June 17, 2006, and the end of April. Federal authorities say the birds died after diving into an uncovered tank and encountering liquids in uncovered storage pits.
Officials say about 40 migratory birds died in western Wyoming between June 1 and Sept. 30 of 2009 after contact with liquids in storage pits.
EnCana didn't immediately return a request for comment after business hours Tuesday.
A hearing is scheduled Aug. 26 in Denver.
