Coal Mining Employment Impacts from Acid Rain Controls

Steam versus Coking Coal and the Acid Rain Program

The Clean Air Act of 1990 initiated a tradable permit program for emissions of sulfur dioxide from coal-fired power plants. One effect of this policy was a large increase in the consumption of low-sulfur bituminous coal by coal-fired power plants. However, lowsulfur bituminous coal is also the ideal coking coal for steel production. The analysis presented here will attempt to determine how the ...

Acid Rain

Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater actually has a pH of about 5.6 (acidic).[Recall from Experiment 1 that pH is a measure of the hydrogen ion (H+) concentration.] The acidity of rainwater comes from the natural presence of three substances (CO2, NO, and SO2) found in the troposphere (the lowest layer of the atmosphere). As is seen in Table I, carbon dio...

Assessing the environmental impacts of coal mining using analytical hierarchy process: A case study of Jharia coal-field, India

Jharia coal-field holds unequivocal importance in the Indian context as it is the only source of prime coking coal in the country. Haphazard mining over nearly a century has led to environmental changes to a large extent such as degradation in the quality of air, water, soil, changes in landform, land-use/land-cover and vegetation distribution. Environmental impact assessment is a process to as...
