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 author cites three reasons to support the view point that new regulations for dealing with and storing coal ash should be created. Nevertheless, the lecturer in the listening material argues that it is unnecessaru to implement new and strict regulations,and opposes the points in the reading material.
Firstly, the author argues that we already have effective regulations, which requires companies dispoosing of coal ash in disposal ponds or landfills to use liner in every step. However, the lecture offers an opposite stand that the existing regilation is not sufficient enough. To be more specific, the existing regulation only requires companies to use liner in new ponds and landfills. Coal ash components in old ponds or landills still do a huge damage to the environment, leading into the soil and contamintaing the drinking water.
In addition, the lecturer casts doubt on the author's second reasond that new regulations may discourage the recycling of coal ash into other products, because consumers will be aware of the danger of recycled coal ash products and stop buying them; and also demonstrates that although the raw material is dangerous, consumers will not stop buying the products of it. For example, products made of another dangerous raw material have been sold for 50 years, illustrating that consumers are not afraid of buying them.
Finally, the author's third reason that higher price for handling coal ash will force power companies to increase the price of electricity, which is not welcomed by the general public, is also counteracted by the lecturer who points out that the result worths paying higher price. Although it will increase total cost about 15 billion for the power companies, the price for the public only rises about one percent on average, which is worthy for the cleaner environment.
