  1. What is the purpose of this permit?  This permitting action is to modify the existing Rail Car Loading process (E9) of emission unit U3 by increasing the aluminum throughput rate. The existing cyclone and metal mesh filter will be replaced with more efficient control devices. The permit also includes installation of insignificant activities in emission units U14 (Aluminum Paste Dryers) and U24 (Mills). The permit contains an existing particulate matter (PM) emission limit and a new PM10 emission limit to ensure the modification is not major for the Prevention of Significant Deterioration (PSD) program. 
  2. Will this permit increase pollution? Construction Permit C-0187-23-0009-V will not increase aluminum emissions, which is both Particulate Matter (PM/PM10) and a Toxic Air Contaminant (TAC). Controlled potential emissions of PM/PM10 and TAC (aluminum) are calculated to decrease by 621 pounds per year. The controlled potential TAC emission (aluminum) are de minimis for emission point E9 (railcar loading process) for purposes of the Strategic Toxic Air Reduction (STAR) Program. The permit documents all standards, monitoring, and reporting to ensure compliance with all applicable regulations.
  3. Does this facility have a history of non-compliance?  There have not been any violations of any of the terms of the present construction or operating permits. See the Compliance History Section of the Statement of Basis.
  4. Where can I find out more? Additional information, including equipment descriptions, potential emissions, and applicable rules, are summarized in the Statement of Basis. The Draft Permit details the application of these rules to the equipment and includes the monitoring, recordkeeping, and reporting that the District believes is necessary to demonstrate compliance.
