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.
Summarize the points made in the lecture, being sure to explain how they challenge the specific arguments presented in the reading passage.
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.
The reading passage states that some power companies think the deciding stricter regulations for handling and storing coal ashes is unnecessary and current regulations are already sufficient. However, the professor in the lecture casts doubt on the points made in the reading passage.
First, considering the reading passage, environmental regulations to prevent coal ash leaking to soil and water already exist. companies have to use liner in every new pond or landfill. In contrast, the professor in the lecture believes that current regulations are not enough because this prevent leaking activities should not be limited to new ponds. Old ponds and landfills can be damaged too and coal ash will leak to water and soil from them.
Second, the reading claimes that stricter rules will make a distraction of recycling and its benefits. Also people may think coal ash is too dangerous to be recycled and then be used again. On the contrary, the professor in the lecture refutes the information presented in the article and makes the point by exemplifying an earlier experience. Mercury have had strict handling rules for many years and besides, recycled and used again without making people affraid. Therefore, the same strategy can be applied to coal ash too.
Third, the author in the reading passage puts forward the idea that disposal and handling costs will increase too much due to new regulations which is not desirable by public. On the other hand, the speaker contradicts the excuse and adds up that the cost will cost about 15 billion dollars which is approximately 1 percent of household electricity cost. Hence, the increase in costs is totally worth considering the influence.
