From: Brian Thomas Printed Circuit Alliance (PCA) Sigma Circuits, Inc. 408-727-9168 x 106 408-727-8859 fax Greetings: Local area manufacrures in the San Jose, CA area are working on a cooperative effort with the Bay Area Air Quality Management District (BAAQMD) developing a permitting handbook and Chapter for the Printed Circuit Industry. We would anticipate that it will eventually be adopted for the entire state of California. We are collecting information regarding emissions from manufacturing processes. Of particular interest are VOC emissions, either calculations, estimates or stack measurements. We also need information on other emissions including acids, formaldehyde, and ammonia. The most difficult area to resolve at this point are resist strippers. Current BAAQMD methodology assumes that all of the organics will be emitted including monoethanolamine. We plan to include estimated emission rates in the permitting handbook. If you have any information that may be of assistance in this effort please e-mail me or give me a call. Regards, Brian Thomas
