Current through Register Vol. 50, No. 9, September 20, 2024
A.
Fugitive Dust. Each person who conducts surface mining activities shall plan
and employ fugitive dust control measures as an integral part of site
preparation, coal mining and reclamation operations. The office shall approve
the control measures appropriate for use in planning, according to applicable
federal and state air quality standards, climate, existing air quality in the
area affected by mining, and the available control technology.
B. Control Measures. The fugitive dust
control measures to be used, depending on applicable federal and state air
quality standards, climate, existing air quality, size of operation and type of
operation, shall include, as necessary, but not be limited to:
1. periodic watering of unpaved roads, with
the minimum frequency of watering approved by the office;
2. chemical stabilization of unpaved roads
with proper application of nontoxic soil cement or dust palliatives;
3. paving of roads;
4. prompt removal of coal, rock, soil and
other dust-forming debris from roads and frequent scraping and compaction of
unpaved roads to stabilize the road surface;
5. restricting the speed of vehicles to
reduce fugitive dust caused by travel;
6. revegetating, mulching or otherwise
stabilizing the surface of all areas adjoining roads that are sources of
fugitive dust;
7. restricting the
travel of unauthorized vehicles on other than established roads;
8. enclosing, covering, watering or otherwise
treating loaded haul trucks and railroad cars to reduce loss of material to
wind and spillage;
9. substituting
conveyor systems for haul trucks and covering conveyor systems when conveyed
loads are subjected to wind erosion;
10. minimizing the area of disturbed
land;
11. prompt revegetation of
regraded lands;
12. use of
alternatives for coal handling methods, restriction of dumping procedures,
wetting of disturbed materials during handling, and compaction of disturbed
areas;
13. planting of special
windbreak vegetation at critical points in the permit area;
14. control of dust from drilling using water
sprays, hoods, dust collectors or other controls;
15. restricting the areas to be blasted at
any one time;
16. restricting
activities causing fugitive dust during periods of air stagnation;
17. extinguishing any areas of burning or
smoldering coal and periodically inspecting for burning areas whenever the
potential for spontaneous combustion is high;
18. reducing the period of time between
initially disturbing the soil and revegetating or other surface
stabilization;
19. restricting
fugitive dust at spoil and coal transfer and loading points with water sprays,
negative pressure systems and baghouse filters, chemicals or other
practices.
C. Additional
Measures. Where the office determines that application of fugitive dust control
measures listed in
§5397. B is inadequate,
the office may require additional measures and practices as
necessary.
D. Monitoring. Air
monitoring equipment shall be installed and monitoring shall be conducted in
accordance with the air-monitoring plan required under
§2711 and approved by the
office.
