Dust levels
Defendants of mining point out that, environmentally, coal mining has two important factors in its favor. It makes only temporary use of the land and produces no toxic chemical wastes. By carefully pre-planning projects, implementing pollution control measures, monitoring the effects of mining, and rehabilitating mined areas, the coal industry minimizes the impact on the neighboring community, the immediate environment, and long-term land capability.
Dust levels are controlled by spraying roads and stockpiles, and water pollution is controlled by carefully separating clean water runoff from runoff which contains sediments or salt from mine workings. The latter is treated and reused for dust suppression. Noise is controlled by modifying equipment and by using insulation and sound enclosures around machinery.
