CONTAMINANTS DISCHARGED

These are classified, under the Pollution Control
Act, 1967, as discharges onto land, into water, and

‘ into the atmosphere. They originate from three areas:
the Minesite, the Plantsite, and the Townsite.

Relative locations of discharges are illustrated

in Appendix C. Monitoring data is summarized in

Appendix D.
Sie MINESITE

a) Discharges onto land. These are barren
waste dumps consisting of coarse broken
serpentine, argillite, and associated
volcanic waste rock. Their discharge is
regulated under the Mines Regulation Act.
Areas on which they are deposited are
essentially barren mountain slopes above

5000' elevation.

Discharges into water. None other than

natural seepage from melting ice and snow.
Prior to Cassiar's mining operations this
melting occurred historically. Coarse
asbestos outcroppings were naturally
exposed and eroded, and are believed to

have caused natural introduction of asbestos
