The Cape Breton Development Corporation (CBDC) located in Cape Breton,
Nova Scotia, in eastern Canada, was established in 1967. its mandate
at that time was to facilitate a phased downsizing of the coal industr
y and developing viable replacement industries. The oil crisis in the
early 1970s changed CBDC's mandate and focus was modified to increase
coal production to support Nova Scotia Power Commission's ''off oil''
policy for their power generators. In the late 1980s the mandate to de
velop viable replacement industries was eliminated and CBDC became pri
marily a coal mining company. CBDC presently operates two underground
coal mines, Phalen Colliery and Prince Colliery, using a retreat longw
all method of mining. Both mines operate beneath the Atlantic Ocean. C
BDC also operates associated infrastructure -- central workshops, a ra
ilroad, coal preparation plant, and international pier.
