(a) The RTO & HRSG Emission Unit (FGOXID Emission Limit I.4) shall not emit more than 21.20 pounds of NOX per hour; (b) The Fermenters Emission Unit (FGFERM Emission Limit I.2) shall not emit more than 1.30 pound of Acetaldehyde per hour. On April 24, 2012, EPA issued a Request for Information to the Facility under Section 114 of the Act, 42 U.S.C. � 7414. On June 5, 2012, Andersons responded to EPA�s Request for Information. 1. Based on the information provided, EPA performed calculations using the hourly NOX emissions in pounds per million British Thermal Unit (lb/MMBtu) recorded by the continuous emissions monitoring system and hourly natural gas flow measured in MMBtu at the Facility, EPA has determined that, from November 8, 2007 through April 16, 2012, Andersons exceeded its permitted NOx emissions limit of 21.20 pounds per hour. Andersons exceeded its allowable emission limits for nitrogen oxides (21.20 lb/hour) and Acetaldehyde emissions (1.30 lb/hour) at the regenerative thermal oxidizers and heat recovery steam generator (RTO)
