employees in offices and generating stations across the province, we
need to manage general waste made up of garbage, recyclables and
organics. Regular waste is sorted on-site according to the requirements of the local landfill, and removed from our facilities by
either certified contractors or municipal waste collection operations.
Industrial waste and special substances
electricity means we have both industrial waste like ash from our
thermal generating stations and special substances, such as PCBs from
old electrical equipment to dispose of. Other examples of industrial
waste include fuel solids and fuel ash, gypsum, oily rags and blasting
grit. We take care to handle and dispose of each type of waste produced
by our operations properly.
primary industrial waste produced by our operations is the ash produced
by burning coal and oil. This is a combination of fly ash (collected
using equipment in the generating station stacks) and bottom ash
(collected at the bottom of boilers). When possible, we sell ash
produced by our thermal generating stations to be used for other
purposes. Fly ash, for example, can be used as a substitute for cement
biphenyls (PCBs) are a group of organic compounds that were used as
fluids to cool and insulate electrical transformers and capacitors. The
manufacture of PCBs was stopped in 1977, but because their use was so
widespread and electrical equipment can remain in service for a long
time, some equipment may still have PCB contamination. We’ve been
implementing programs to remove PCBs from service over the past several
years in line with federal regulatory requirements.
