* Decree extends deadline for compliance with selenium effluent limitations * Co to pay a $50,000 penalty
March 24 (Reuters) - Patriot Coal Corp PCX.N said it agreed to pay a $50,000 penalty to settle claims under the Clean Water Act relating to its Apogee and Hobet mining complexes in West Virginia.
The consent decree with Ohio Valley Environmental Coalition Inc and West Virginia Highlands Conservancy Inc extends the deadline for compliance with selenium effluent limitations at outfalls to April 5, 2010 from June 30, 2009.
The company also agreed to implement a $350,000 pilot project that uses reverse osmosis technology to evaluate its feasibility for use in selenium treatment in coal mines.
Last month, the company agreed to pay $6.5 million to settle claims that it violated its permits more than 1,400 times, between January 2003 and December 2007, at its mining complexes in West Virginia. [ID:nBNG391861]
