Main Plant Digester Cleaning and Rehabilitation Project
The Project is 80% complete -the first phase of the project is complete with the secondary digester now cleaned and back in service - The Primary Digester is now clean and ready to be placed back in service. All that remains is some concrete restoration work outside of the Roll Up doors - in front of the plant. That work will begin at the beginning of the new year. We are looking at February final completion of this project where our neighbors can expect things to be back to normal on Mar West in regards to noise, parking and deliveries.
