Classification certificates are required to be posted in the subsystem or facility at all times. If your municipality or operating authority no longer has the original of this certificate, you can request a new copy through the OWWCO office.
Requests must be made by an authorized representative of the subsystem or facility owner. There is no fee, however, the request must be submitted in writing.
