The EPA is withdrawing the interpretative rule published in the Federal Register on April 21, 2000, at 65 FR 21363. That interpretative rule was intended to clarify the construction by EPA of the applicability of sections 112(g) and 112(j) of the Clean Air Act (CAA) to all stationary combustion turbines and waste heat recovery units in combined cycle systems. An administrative error led to publication of a preliminary draft of the interpretative rule, rather than the final interpretative rule EPA intended to publish. Concurrent with this withdrawal of the incorrect version of the interpretative rule published on April 21, 2000, EPA is publishing elsewhere in today's Federal Register a corrected version of the interpretative rule.
