During an inspection in 2006, the Indiana Department of Environmental Management (IDEM) discovered an aluminum melting furnace at Azimow and Culbertson Scrap Company (Azimow). It was revealed that this furnace was subject to the requirements of 40 C.F.R. Part 63, Subpart RRR (Secondary Aluminum NESHAP). IDEM sent Azimow a letter on January 9, 2006, informing Azimow of the furnace's applicability to the federal requirements. Azimow was required to notify, keep records, and test the furnace's emissions by March 24, 2003. Azimow did not comply with any of the Secondary Aluminum NESHAP requirements, but when it received the letter from IDEM, immediately shut down the furnace. On December 11, 2006, IDEM referred the enforcement case to U.S. EPA. On April 4, 2007, a Finding of Violation (FOV) was issued to Azimow, identifying the violations of the Secondary Aluminum NESHAP. During a follow-up inspection by IDEM on May 30, 2007, it was confirmed that Azimow was no longer operating the non-compliant furnace. As a result of Azimow's willingness to cooperate with U.S. EPA by dismantling the furnace, thereby ensuring no further releases of dioxins and furans into the atomosphere, and the financial situation of Azimow, U.S. EPA agreed to settle this case with a $1,000 penalty.
