Environment and Climate Change Canada has issued hefty fines to the University of British Columbia and CIMCO Refrigeration for releasing ammonia-laden water into a tributary of the Fraser River in Vancouver. According to a written statement, UBC was fined $1.2 million and CIMCO $800,000 stemming from a complaint about an ammonia odour at an outfall ditch connected to Booming Ground Creek in Pacific Spirit Regional Park on Sept. 12, 2014. The ministry says UBC and CIMCO were fixing the refrigeration system at Thunderbird Arena at the university's Vancouver campus when they purged residual ammonia vapours from the system into a storm drain that flowed into a ditch and then the creek.
