Burning coal in power plants produces a waste product called coal ash, a material that contains small amounts of potentially harmful chemicals. Environmentalists in the United States are concerned about the damage such harmful chemicals may be doing to the environment and suggest that the United States government should create new, much stricter regulations for handling and storing coal ash.
However, representatives of power companies take the opposite view: they argue that new regulations are unnecessary and might actually have negative consequences. They use the following arguments to support their position.
Regulations Exist
First, power company representatives point out that effective environmental regulations already exist. For example, one very important regulation requires companies to use liner—special material that prevents coal ash components from leaking into the soil and contaminating the surrounding environment. Companies that dispose of coal ash in disposal ponds or landfills must use liner in every new pond or landfill they build.
Concerns About Recycling Coal Ash
Second, some analysts predict that creating very strict rules for storing and handling coal ash might discourage the recycling of coal ash into other products. Currently, a large portion of coal ash generated by power plants is recycled: it is used, for example, in building materials such as concrete and bricks. Recycling coal ash reduces the need to dispose of it in other ways and presents no environmental danger. However, if new, stricter rules are adopted for handling coal ash, consumers may become concerned that recycled coal ash products are just too dangerous, and may stop buying the products.
Increased Cost
Finally, strict new regulations would result in a significant increase in disposal and handling costs for the power companies—perhaps as much as ten times the current costs Power companies would be forced to increase the price of electricity, which would not be welcomed by the general public
Both the reading passage and the lecture discuss whether the United States government should create stricter regulations for handling and storing coal ash. The passage provides three reasons to claim that new regulations might have negative consequences. However, the professor of the lecture casts doubt on all the reasons mentioned in the passage.
First of all, the passage states that the effective environmental regulations already exist. For example, the regulation that requires companies to use liner in every new pond or landfill they build. Nevertheless, the professor counters the passage by pointing out that the regulation mentioned in the passage only apply to new ponds and landfills, but there is no regulation that applies to old ponds and landfills. Thus, it is necessary to create regulations that apply to new and old facilities.
Secondly, the passage mentions that creating very strict rules for storing and handling coal ash might make consumers become concerned that recycled coal ash products are too dangerous. Notwithstanding, the professor disagrees with the passage by citing one example. She claims that mercury, a dangerous material, has been regulated by strict rules for more than fifty years, yet only few consumers concerned about products made in this material.
Finally, the passage argues that strict new regulations would result in a significant increase in disposal and handling costs for the power companies, which would force them to increase the price of electricity. However, the professor refutes the passage by arguing that creating strict rules is well worth the additional cost. She says that if the cost for the companies increase fifteen billions, though it may sounds a lot, the price of electricity for each household would increase only one percent, which is not significant at all.
