On March 18, 2021, MRO staff performed a compliance inspection to be able to generate a staff report for permit renewal.
The sludge is treated aerobically and pH is the primary indicator that stabilization gas occurred. Lime is added to the
sludge to achieve reduction. The primary digestor can hold up to 400,000 gallons of sludge. The sludge is treated at one
time in the primary digestor before Land Application.
