AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revised opacity limits for three casting complexes at ALCOA Warrick Operations, which were submitted by the Indiana Department of Environmental Management (IDEM) on January 13, 2000 as amendments to its State Implementation Plan (SIP). ALCOA Warrick Operations is a primary aluminum smelter located in Newburgh, Indiana. The revised limits allow higher opacity emissions during fluxing operations at three casting complexes.
