Current through Register Vol. 50, No. 6, June 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.
