§ 8107-22.4.7. Prevention of fugitive dust.

There shall be no fugitive dust leaving the stockpile site. Fugitive dust shall be controlled in accordance with the following:

a.

All dust generating activities shall cease when wind speeds exceed 25 mph average over one hour or during high wind events. High wind events are defined as wind of such velocity as to cause fugitive dust from the permit area to blow off-site.

b.

Fugitive dust throughout the site shall be controlled by the use of a watering truck. Water shall be applied to all stockpiles, onsite roads and access roads, which have not been otherwise treated to prevent fugitive dust.

c.

If it is observed at any point in time that fugitive dust is blowing off-site or off access roads, and additional watering activities are insufficient to prevent fugitive dust, dust generating activities shall be immediately curtailed until the conditions abate.
