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 starts the article by saying that implementing strict rules for managing hazardous chemicals are unnecessary. But the lecturer firmly denies these ideas made by the passage, she stands in opposite position that govt. should impose firm rules in managing dangerous materials caused by burning coal in power plan
There is previously existed rule to dispose of poisonous materials, companies have to use liner in newly constructed ponds or landfills preventing leakage of hazardous material into the environment. the professor doubts on its capacity and adds that companies are not bounded to erect new ponds or landfills so there is a chance for polluting soil by these disposals.
Some critics concern that strict rules increase the redundancy of recycling poisonous material, but professor believes that this idea has no solid evidence. In her illustration, she mentions imposing strict rule on managing potentially harmful mercury by recycling does not stop its use by people.
Disposal cost must increase if strict rules are followed by the company that may lead to raise the price of electricity. The lecturer think this increased amount of disposal cost does not affect the electric bill of the company.
To sum up, the author and the lecturer have conflicting ideas of imposing strict rules on disposing of hazards.
