PCBs in Use and in Storage (page 2 of 3)

2. Ontario

Ontario. Ministry of the Environment. Annual report on PCBs in storage. July 2000. (CD-ROM).

The inventory does not include all federal PCB storage sites which are under Environment Canada jurisdiction. There were 1574 active PCB storage sites in Ontario as of July 2000, "however, the quantities and site information are constantly changing".

The Ontario data is divided into quantities of high-level PCBs (>10,000 ppm) and quantities of low-level PCBs (<10,000 ppm), and within those two groups, into various types of PCBs. The totals for the different categories are as follows:

In December 2001, the Ontario Ministry of the Environment announced a hazardous waste plan with the intent to destroy remaining PCBs in storage within a fixed time period. PCB waste in storage will be required to be destroyed within 3 years, and a destruction schedule for PCB wastes that are placed in storage after the regulation takes effect. PCBs stored at sensitive locations such as schools and hospitals will have an accelerated deadline of destruction within one year of the time the regulation takes effect.

The plan states that about 99,000 tonnes of PCB waste remain in storage at over 1,000 sites in Ontario. 7,000 tonnes are high level (>1% PCBs) and 92,000 tonnes are low level PCB wastes. Every year more PCBs are being placed in storage as electrical equipment is being decommissioned.
