Hi Ruth Ann - From my article on renovations:
https://pubs.acs.org/doi/abs/10.1021/acs.chas.2c00008
For
floor drains in laboratories, it is also useful to know that
the Environmental
Protection Agency (EPA) considers wastewater rinses drained
into the sewer
system from showers not hazardous as a de minimis loss.3
Unless restricted locally by the publicly owned
treatment works (POTW), the drains should be installed if
desired (Figure 1).
(3)
Environmental Protection Agency.
Identification
and Listing of Hazardous Waste. 40 C.F.R. §
261.3(a)(iv)(D) (1980). https://www.ecfr.gov/current/title-40/chapter-I/subchapter-I/part-261
(accessed 2022-01-14).
Hope this helps,
Sammye

Good Afternoon,
Once again the following concern has
arisen: lab eyewash/safety shower units cannot drain with
regular water due to possible contamination of the
environment, e.g., if someone were washing off a sulfuric acid
spill. Can someone provide a reference that this is (or is
not) okay?
Thanks!
