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 lecture both discuss about new regulations for handling and storing ash coal which potentially contains harmful chemicals for the environment. The author belives that existing regulations are sufficient and there is no need for new ones, but the professor contrasts the author's oponion and belives that very strick rules should be implemented for handling coal ash by power plant comanies. Moreover he rebuts each of the reasons provided in the passage.
First, the author claims that effective rules already exist, but the lecturer rebuts this point and contends that these regulations are not sufficient. Furthermore, he elaborates that rules for using liner-special material to prevent coal ash components from leaking into soil are just in place for new ponds or landfill and they are not applied on old ponds or grounds that their liner material is damaged. So, this causes leackage of harmful chemicals to ground water and seriously harms the environment.
Second, despite the author's belief that use of strict regulations will discourage the recycling of coal ash into other products, the lecturer points out that these rules are being applied on other chemicals and had not affected their recycling. For example, there is very strict rules for handling mercury, but still it is being recycled successfully for more than 50 years and consumers are not afraid of using these recycled products. Therefore, use of these rules won't have any serouis effect of inclination towards recycling coal ash.
Third, although as the reading illustrates these new regulations will cost extra, however the professor belives that this extra cost is worth the cleaner environment. Additionally he states that this rules will cost around 15 billion dollars, which in itself seems very huge, but calculations shows that this amount sums up to just 1% increase in each household electricity costs, which is quite tolerable.
