*Update for BNC PM-Shutdown --* Necessary maintenance is complete, the BNC chemical exhaust systems and toxic gas systems have returned to normal. **All labs, the cleanroom, and solvent hoods have reopened (thus all door signs have been removed).** Unfortunately, the quality of the Ultra Pure Water (UPW) system has not yet stabilized. **As a result, the acid hoods remain closed until further notice.** We will monitor the UPW system over night and update all users on the status by Friday at noon. Thank you for your patience during this preventative maintenance process and your understanding during this extended delay. Sincerely -- BNC Staff
