Hello Patrick,
 
our aqueous disposal procedures require labs to obtain our direct 
authorization BEFORE making aqueous disposals in lab sinks.  at the time 
of disposal lab personnel MUST dilute to the MPC and maintain ongoing 
log of ALL disposals, including waste water from cleaning flasks, tubes, 
columns, etc.  we review these logs during our lab inspections. in some 
cases we require a quarterly summary of disposals (isotope/activity/ and 
volume) and additionally, once a year we require all labs to submit an 
annual total.  hope this is of interest.
