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.
The reading and the lecture both are about coal ash and its impact on the environment. The author of the reading feels that creating new regulations to save the environment from the chemicals disposed of coal ash will have a negative impact. The lecturer challenged all the claims made by the author and describes them as below.
Firstly, the writer mentions that the power companies are on effective strict regulations. Additionally, he proves it by taking an example of the liner, which is used to prevent coal ash components from leaking into the soil and damaging it. However, the lecturer says that the regulations they have now are not sufficient to save the environment. For instance, the liner is not been utilized to line the old ponds and filling them. Moreover, chemicals drained from coal ash is contaminating the drinking water and affecting many people.
Secondly, the article predicts that making strict rules for storing and handling coal ash probably discourages recycling of coal ash into various products, and also it shows a decline in customers buying them. The academician refutes this point and brings about the mercury, though it is hazardous to the environment, the government made strict rules to handle it for longer time and consumers have very few complaints about it. So people are not concern about making strict rules.
Finally, the author mentions that making strict rules of handling and disposing of coal ash will increase the cost of electricity by about ten times. On the other hand, the tutor mentions that according to analysis cost will be increased by 50 million dollars which is huge. It does not affect people even though the cost is increased because the increase in the electricity bill is only by 1 percent to each family. Furthermore, it is not a big deal to pay for the people in order to save the environment.
