Look into the Hazardous Waste regulations that exist in area where you are.     In California and other states, generators are prohibited by regulation from treating a hazardous waste, including acid-base neutralization, without a Permit from the State Agency (some minor exceptions), and Treatment Permits are a major headache and expense to get - paper work, inspections, record keeping, annual Permit Fee$ ....  

 If your state or county or the CUPA you deal with has similar regulations, this may be an argument against installing an "acid waste treatment tank" in your building.   Instead, create and document waste containment procedures (organized and managed chemical waste collection) to show minimal acid release into the plumbing system.   This may involve some or a lot of staff training.    I'm not sure what the recent experience at Auburn is concerning chemical waste handling. 

Attorneys may get involved if there is a conflict between the Plumbing Code and Hazardous Waste Regulations.

Best of Luck.

Subject: [DCHAS-L] Acid Neutralization Tanks

We are interested in getting a variance from the plumbing code requirement for installation of Acid Neutralization Tanks for our lab buildings. I would like to hear from others who have been successful in eliminating these tanks from their campus'.  Please reply to this post or feel free to contact me off-line at nelsost**At_Symbol_Here** . I'd like to find out what strategy was used and what data if any was developed.

Also, I seem to recall a study that one institution did on their lab building waste water effluent.  If anyone has a copy or can point me in the right direction I would be grateful.

Best regards,


Steve Nelson
