1 Iron Steel Overview

  2. 2. INTRO <ul><li>On April 22, 2004, USEPA promulgated the Federal standard, Iron & Steel Foundries NESHAP (National Emission Standards for Hazardous Air Pollutants) 40 CFR Part 63, Subpart EEEEE. </li></ul>
  3. 3. ALERT!!!!! <ul><li>On May 20, 2005, USEPA promulgated the final amendments to the original Subpart EEEEE NESHAP promulgated April 22, 2004. The amendments clarified the Sections §63.7700, §63.7735 and §63.7765. The amendments are intended to reduce compliance uncertainties. Because the work practice standards became effective April 22, 2005 (1 year after promulgation) the clarifications contained in the direct final rule amendments are time-critical. </li></ul>
  4. 4. NOTICE!!!!! <ul><li>There is an EXISTING SOURCE requirement to comply with work practice standards in §63.7700 (b) or (c) no later than April 22, 2005 </li></ul>

  8. 8. TYPICAL FACILITY <ul><li>Video: 12 minute video on “The Process of Metal Casting” </li></ul><ul><li>Cast Metals Institute (CMI) </li></ul>
  9. 9. APPLICABILITY: Who is covered by this rule? (Subpart EEEEEE, §63.7681) <ul><li>Own or operate an EFFECTED SOURCE at a facility that is a major source, </li></ul><ul><li>Located at a major source, or </li></ul><ul><li>Part of a major source of hazardous air pollutants (HAPs). </li></ul><ul><li>NSPS for NEW sources of VOC </li></ul>
  10. 10. Effected Source <ul><li>NSPS; FOUNDRY operations involve VOCs </li></ul><ul><li>NESHAP similar definition; </li></ul><ul><li>VOCs vs VOHAPs; similar criteria and an increase in stringency </li></ul><ul><li>Any new or reconstructed source (as defined in § 63.2) before 12/23/2002 is an existing facility and that is a major source and is an iron and steel foundry. </li></ul><ul><li>Any new or reconstructed source after 12/23/2002 is a new source. </li></ul>
  11. 11. Effected Source (cont’d.) <ul><ul><li>Facility or portion of facility that melts scrap, ingot, and/or other forms of iron and/or steel. </li></ul></ul><ul><ul><li>Facility pours the resulting molten metal into molds. Mold sand shakeout operations. </li></ul></ul><ul><ul><li>Final products introduced into commerce. </li></ul></ul>
  12. 12. What are Some Operations’ Emissions Impacted by Subpart EEEEE? <ul><li>Metal melting furnaces; </li></ul><ul><li>Scrap pre-heaters; </li></ul><ul><li>Pouring areas; </li></ul><ul><li>Pouring Stations; </li></ul><ul><li>Automated conveyor and pallet cooling lines; </li></ul><ul><li>Automated shakeout lines; </li></ul><ul><li>Mold & core making lines; </li></ul><ul><li>Fugitive emissions from foundry operations. </li></ul>
  13. 13. FOUNDRY Operations Examples <ul><li>EXAMPLE: For pre-heaters . generally, the rule requires that a scrap selection and inspection program limit to the extent practicable, the amount of organic HAP precursors (i.e., oils and other organic liquids) entering a scrap pre-heater and must comply with the work practice standards in the rule. </li></ul>
  14. 14. EXAMPLES (cont’d.) <ul><li>2. EXAMPLE: If as foundry casts in multiples of a wide range of alloys, but has a significant iron or steel content, the facility is subject to Subpart EEEEE. The facility should contact the state administrator for guidance. </li></ul><ul><li>3. EXAMPLE: USEPA has revised the finalized the designation for effected source to include a broad definition of the iron/steel foundry that eliminates the somewhat artificial separation of the mold and core-making processes which can often occur at close proximity, if not in conjunction with the casting/poring operations. </li></ul>
  15. 15. EXAMPLES (cont’d.) <ul><li>4. EXAMPLE: The final rule avoids the cases where an existing foundry might make minor equipment changes that could subject one process or a single piece of equipment to the new source emissions limits. </li></ul><ul><li>5.
