Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
I (Daniel Boss) conducted a compliance evaluation inspection at the Elk River WWTP on 8/16/2018. I
met with Christian Montgomery (ORC) and Neil Reece (Backup ORC) for the inspection. The plant
appeared to be well operated and maintained.
Mr. Montgomery informed me that the plant had undergone $130,000 in upgrades just two weeks prior
to the inspection. New blowers, diffusers, a control panel, and a standby generator had been installed.
