METHODS SPECIFIED:

1. Total particulate: isokimetric sampling on a 0.3 micrometer pore
size glass fibre filter followed by gravimetric analysis.

2. Sulphur dioxide: continuous analyzer on discharges over 250 ppm.

Objectives for unusual pollutants such as fluoride, zinc, and others
do exist, but have been excluded from this report since they are
essentially irrelevant to Cassiar.
