Toronto Hydro CR Report 2016

INTRODUCTION MATERIALITY AND STAKEHOLDER ENGAGEMENT OUR CITY OUR OUR PEOPLE ENVIRONMENT GLOSSARY AT A GLANCE A breakdown of Toronto Hydro’s waste POLYCHLORINATED BIPHENYLS Similar to most electrical utilities in Canada, Toronto Hydro owns and operates equipment that has oil containing PCBs. The operation of this equipment is compliant with the PCB Regulations under the Canadian Environmental Protection Act, 1999. In recognition of the persistent ecological effects of PCBs, Toronto Hydro is actively removing and safely destroying equipment and oil containing PCBs in excess of the standards prescribed by federal and provincial laws. This removal and destruction has been accelerated in recent years and has been enabled by proactive inspections of equipment suspected of having oil containing PCBs and testing of oil in equipment for the presence of PCBs. In 2016, Toronto Hydro conducted inspections and oil sampling for more than 3,000 transformers. In 2016, approximately 10,000 kilograms of material75 and 8,500 litres of liquids containing PCBs were sent for destruction. In 2015, approximately 21,000 kilograms of material and 40,000 litres of liquids containing PCBs were sent for destruction. The amount of solid waste containing PCBs decreased by approximately 53% from 2015. The liquid waste containing PCBs decreased by approximately 80% from 2015. The majority of contaminated liquid in 2015 came from a single location. Approximately 27,600 L of contaminated water was identified at the location as a result of Toronto Hydro’s diligence in testing suspect contaminated water. The water was contained at the location and shipped for disposal. The source of the contamination was identified and subsequently removed and sent for destruction. The graph on the following page displays the trend in removal and destruction of equipment and oil containing PCBs since 2013 and reflects the accelerated effort to remove this substance from the system. OUR ENVIRONMENT I TORONTO HYDRO 83 NON-HAZARDOUS WASTE Eight hundred and thirty-seven metric tonnes of waste were recycled or composted and 479 metric tonnes were sent to landfill in 2016. In 2015, 1,000 metric tonnes of waste were recycled or composted and 478 metric tonnes were sent to landfill. This resulted in annual waste diversion rate improvement of 5% from 2014. These numbers do not include the amount of waste recovered through the investment recovery process. INVESTMENT RECOVERY PROGRAM Toronto Hydro has an investment recovery program where valuable waste metals are sold for reuse. In 2016, 1,733 metric tonnes of scrap metals were sold through this program. When added to the recycling totals above, Toronto Hydro’s waste diversion rate increased to 85%. HAZARDOUS WASTE In 2015, approximately 1.26 million litres and 252 metric tonnes of hazardous waste were sent for destruction or recovery. In 2016, approximately 1.38 million litres and 342 metric tonnes of hazardous waste were sent for destruction or recovery.
