The Challenge:
To meet the cumulative noise requirements from two plants in a quiet, rural town.
The Innovation:
When a cogeneration plant was to be built in quiet rural Thorold, Ontario next to the Abitibi Pulp and Paper plant and close to several residences, we helped build the new plant with noise reduction in mind. As part of the design, the Ministry of Environment required us to assess the noise from both plants on a cumulative level which meant that we had to design to a lower limit than we would have otherwise done. We used sophisticated 3-D environmental noise modelling to accurately account for all noise sources so we could create and design customized noise controls for the specific sources that required it. Today the plant satisfies all the requirements and operates with no noise complaints from local residents.
