Folks:

Since the acid neutralization system is now "fixed" we can pour waste KOH
and TMAH (as long as it has no restricted metals or other chemicals mixed
in with it) down the drain. Please keep an eye on the amber light by the
GaAs acid bench. If it starts flashing stop pouring everything/anything
down the drain.

If you have any questions about this please let me know.
