53rd ACS Northwest Regional Meeting The 53rd ACS Northwest Regional Meet­

ing (NORM '98), sponsored by the ACS Richland Section, will be held Wednes­

day. June 1". through Saturday, June 20, at Columbia Basin College. Pasco, Wash. The key­note address will be presented by Nobel Laure­ate Glenn T. Seaborg. There will be a separa­tion science and technology symposium to honor Une Bray, the 199" Richland Section Chemist of the Year. In addition, a variety of workshops, including "Minority Affairs," "Gov­ernment Affairs," "Eichrom Industries Lie. West-em Users' Workshop." and "Anahtical Chemists in Industry," sponsored by Procter & Gamble, will be conducted during the meeting.

Three demonstration/tour modules at the Environmental Molecular Sciences Lab­oratory (EMSL) at Pacific Northwest Nation­al Laboratory will be held in conjunction with the meeting. The topics of the three modules will be "Collaboratorv/Molecular

Modeling. NMR Spectroscopy," and "Ca­talysis. Surface Science, Process Science." A bus tour of the Department of Energy's Hanford Site will also be offered.

Por more information, contact the general chair. Karen E. Grant, phone (509) 547Ό511 ext. 261, e-mail: kgrant@ctc.edu; the pro­gram chair. Timothy L. Hubler, phone (509) 373-0.2-*9. e-mail: tim.hubler@pnl.gov; or see the Internet site at http://www.pnl.gov/ norm98/inde\.htm.

Special Events A social mixer will be held concurrently with the poster sessions on Wednesday evening, and a wine-tasting will be held concurrently with the poster session on Thursday. The 50th an­niversary of the founding of the ACS Richland Section will be celebrated with a banquet and will feature presentation of the Regional High School Teacher Award. Scenic cruises on the

Columbia River will be offered on Thursday and Friday; this four-hour tour passes through the Hanford Reach, the last free-flowing sec­tion of the river. Two winery/specialty food tours are offered on Saturday afternoon. The first tour features local wineries, microbrewer-ies, and specialty food businesses in Prosser, Wash., and the second tour provides a progres­sive gourmet meal while tasting wine at three wineries.

Vendor Exposition An exposition will be held in Hawk Union Hall Thursday and Friday and will feature the latest developments and advances in chemical instrumentation, technical literature, and oth­er products and services of interest to chem­ists. Those interested in obtaining exposition space should contact James A. Campbell at (509) 3760899.

Student Affiliates/ Undergraduate Activities The undergraduate program includes a lun­cheon discussion with Glenn T. Seaborg on Friday and a workshop presentation on "Ana­lytical Chemists in Industry" sponsored by Procter & Gamble on Saturday from 9 AM to 2 PM. The workshop, which includes lunch, is followed by a free scenic cruise of the Co­lumbia River for student affiliates. There will
