That may or may not be true in the case that initiated this discussion, but I have been told on several different occasions by differen t individuals (county inspectors, mainly) that shower discharge could not be released and had to be contained.
So this IS a common misconception among local officia ls, and I for one very much appreciate being made aware of the EPA letter!!!!!
This listserve is a valuable resource! Thanks to all w ho contribute!

My understanding is tha t the curb is meant to keep any spill that may occur in the laboratory from reach ing the drain; it is not meant to contain the drench water. There has bee n no mention of containing or collecting the drench water (thank goodness).

How will the 1” high curb prevent 300-600 gallons of water (with the hazm at) from entering the floor drain? Looks like normal governmentese.

I am currently involved in construction of two new laboratories and was instructed by the city commercial building review department to include a 1" high curb around the shower area to keep hazmat from entering the f loor drain in the event of a spill. Also, the curb has to be sloped on bot h sides to allow accessibility.
