Biodegradeable LSC Cocktails

["Sue M. Dupre" <dupre@arundel.Princeton.EDU>]

Our researchers are required to use LSC cocktails with flashpoints 
above 140 degrees F.  Our radioactive waste broker does not 
have a hazardous waste permit in New Jersey and can not transport 
hazardous wastes, so we made the change several years ago to 
accomodate our broker.  None of our researchers ever complained about 
being required to use the higher flashpoint cocktails.

We do not allow drain disposal of the "biodegradeable cocktails" for 
two reasons:  1) we're highly suspicious of the manufacturers'  
claims that the materials are environmentally innocuous (we haven't 
thoroughly researched this but have heard some arguments that the 
materials are not as nontoxic as claimed) , and 2) it's still relatively 
cheap to send LSC wastes off for disposal at Permafix.
