THE FOLLOWING PARTICULATE EMISSIONS CONTROL MEASURES MUST BE USED FOR COMPLIANCE
PURPOSES ON THE ACTIVITIES COVERED BY THIS PERMIT APPLICATION, AS REQUIRED BY THE AIR
QUALITY CONTROL COMMISSION REGULATION NO.1, Section III.D.1.b. THIS SOURCE IS SUBJECT TO THE
FOLLOWING EMISSION GUIDELINES WHICH MAY BE ENFORCED ONLY AS PROVIDED IN REGULATION NO. 1,
Section III.D.1.e.:
Mining Activities - Visible emissions not to exceed 20% opacity, no off -property transport of
visible emissions. (Reference: Regulation Number 1, Section III.D.2.d.(iii))
b. Haul Roads - No off -property transport of visible emissions must apply to on-site haul roads,
the nuisance guidelines must apply to off-site haul roads. (Reference: Regulation Number 1,
Section III.D.2.e.(iii))
C. Haul Trucks - There must be no off -property transport of visible emissions from haul trucks
when operating on the property of the owner or operator. There must be no off -vehicle
transport of visible emissions from the material in the haul trucks when operating off of the
property of the owner or operator. Reference: Regulation Number 1, Section III.D.2.f.(iii))
Blasting Activities - Only the no off -property transport emission limitation guideline must apply
to blasting activities. (Reference: Regulation Number 1, Section III.D.2.i.(iii))
Control Measures
1. Adequate soil moisture must be maintained in topsoil and overburden to control emissions during
removal. Watering must be implemented if necessary.
2. Topsoil stockpiles must be compacted and revegetated within one year.
3. Emissions from material handling (i.e. removal, loading, and hauling) must be controlled by
watering unless natural moisture is sufficient to control emissions.
4. Unpaved haul roads must be treated with chemical stabilizer per manufacturer's recommendations
and watered as often as needed to control fugitive particulate emissions. This control measure
does not apply to haul roads located at the base of the pit which are created on a temporary ad
hoc basis. These in -pit roads must be watered as needed to control fugitive particulate emissions.
5. Reclamation works and sequential extraction of material must be initiated to keep the total
disturbed areas at any one time to a minimum.
6. Coal stockpiles must be treated with chemical crusting agents and watered as needed to control
fugitive particulate emissions.
Drilling of overburden for blasting, must employ hoods and water spray units. Coal drilling must
utilize deflector plates to localize particle distribution around each drill hole.
8. Sequential blasting must be implemented for particulate reduction. No blasting must take place
when wind speeds exceed 30 MPH.
