Why are charges proposed for nitrogen and phosphorus for amounts that are over the By-law limits?
The charges are to recover the extra cost to treat these substances to meet the Environment Act Licence conditions imposed on our three wastewater treatment plants. The West End wastewater treatment plant has already been upgraded to reduce both nitrogen and phosphorus, and a facility to partially reduce nitrogen and phosphorus at the North End plant has been completed. Plans are underway to upgrade both the North End and the South End plants so that they will fully meet licence conditions for the reduction of nitrogen and phosphorus.
