T he theme “Applying Common Sense” ties in with the “Common Sense Initiative” (CSI) now being implemented by the U.S. Environmental Pro-

tection Agency (EPA). The electroplating and surface finishing industry has been selected as one of six to participate in this new program. The American Electroplaters and Surface Finishers Society (AESF) is committed to helping industry understand the CSI and participate in it. In February, EPA Adminis- trator Carol Browner and some of her key staff addressed an AESF/EPA-spon- sored conference. Now AESF takes that meeting a step further at SUR/FIN@ ‘95, with two sessions that will thoroughly explore the CSI and help industry learn of “cleaner, cheaper, smarter” ways of achieving compliance. Speakers include top-level EPA staff and knowledgeable industry representatives:
