At the conclusion of our meeting, Sarah asked if we would summarize the air regulations (especially those associated with PSD/NSR Permitting) that were imposing a significant burden on the metalcasting industry. Attached is a letter prepared by a working group of the AFS Air Quality Committee and others which summarizes our major issues with current air quality regulations and includes recommendations as to how they could be improved/modified. We have also echoed our support for reinstituting the Sector Strategies Program which we felt was very beneficial not only to industry, but also to the agency. While we have attempted to summarize our issues in this letter, we realize that there may be additional questions regarding these issues and some additional detail may be necessary in order to fully understand our perspective and our suggestions for improvement. Toward that end we want you to know that we would be willing to follow up this letter with a meeting between staff from the USEPA and technical experts from the metalcasting industry at a mutually acceptable date and time in order to facilitate a better understanding of our issues and our suggested improvements/modif cations. Again, thanks for meeting with us and for your willingness to consider issues of importance to the metalcasting industry. Dan Dan Oman, P.E. Senior Associate Haley & Aldrich, Inc. 455 E.
