Kaiser Aluminum Fabricated ProductÂs (Kaiser) plant in Kalamazoo, Michigan, is subject to the Secondary Aluminum Production NESHAP at 40 C.F.R. Part 63, Subpart RRR. Kaiser has constructed a new aluminum meting furnace at the plant. The NESHAP requires that Kaiser conduct performance testing of the furnace for emissions of dioxins and furans within 90 days of start-up, which was on or before May 5, 2010. Kaiser informed EPA that, for a variety of reasons, it would not be able to operate the furnace at its highest production level required for testing by May 5, 2010. Since the NESHAP does not have provisions for extending the 90-day deadline for conducting performance testing, this order to requires testing by July 30, 2010, in accordance with the provision at 40 C.F.R. § 3.1511(b). It also requires Kaiser to submit the test results to EPA by September 30, 2010.
