Extension of public comment period.


The EPA is announcing a 30-day extension of the public comment period on the proposed response to the United States Court of Appeals for the District of Columbia Circuit (D.C.

Cir. 1999).


Comments on the proposed response to the remand must be received by February 13, 2002.
