1. /§ ABSTRACT AND RECOMMENDATION

This brief provides an overview of the company's
asbestos Mine-milling operations at Cassiar,
British Columbia. The nature Be the contaminants
discharged, their control measures, and capital
expended for environmental upgrading is presented.
A summary of monitoring data obtained in recent
years demonstrates that progressive improvement

is being achieved. Not all areas at the Cassiar
operations, however, meet the existing Beer Bs
Level A Objectives. Upgrading of these areas is

still in progress.

It is our opinion that the existing Pollution
Control Objectives for the Mine-milling industry
are sufficently stringent to meet the requirements

of the Pollution Control Act, 1967.

As no specific Asbestos Objectives have yet been
set, it is our recommendation that consideration
be given to adoption of a Level A emission Objective
of 2 fibres per cubic centimeter, the limit recently

adopted by Environment Canada.
