The ERL pumps the existing leachate tanks on a regular schedule. Leachate will not be allowed to collect on the liner to a depth exceeding one foot due to the leachate-holding tank being full. The facility is approved to recirculation leachate. Remedies for problems arising from leachate recirculation include, but are not limited to, the cessation of leachate recirculation and reverting back to traditional leachate treatment.
