By midnight, Wednesday, Nov. 2, the smelly Lowell biodigester must be odorless.
During the past month, the biodigester ceased operations in order to pinpoint the smell.
They believe they've located the issue and resolved it with the installation of a carbon absorption filter. The Lowell Police Department told WZZM several weeks ago that complaints had started back up again.
But City Manager Mike Burns said complaints stopped as of last Tuesday.
"Their going to be doing emissions testing monthly, but the biggest thing is that if there's an odor within the confines of the facility then they would not be in compliance and would be shut down," Burns said.
Burns said overall the process has gone pretty smoothly and said it seems like the issue will be resolved.
