Thinking out loud:
Reviewing the UCalifornia's settlement with the LADA's office, I notice that the chemical classification list that requires SOP development includes a variety of chemicals, such as nitric acid, perchloric acid, hydrochloric acid, etc. without a description of what concentration this requirement applies to. I wonder if there was a discussion of a de minimus concentration below which the hazards of these chemicals are such that their use doesn't trigger that requirement...
