Fourth Contest Winner… Next Quiz Question!

 We have a winner for our fourth quiz question!  Toni Radtke of Dairyland Power Cooperative – an electrical generation and transmission cooperative headquartered in La Crosse, Wisconsin – was selected at random from the 10 correct responders to last week’s coal ash question.

But before we get to the correct response, here is the contest question for this week:  What is the name of the U.S. Environmental Protection Agency’s program that actively promotes the recycling of coal ash?

If you think you know the answer, e-mail it along with your name and contact information to

Last week’s question was: What temple to all the gods of ancient Rome is a nearly 1900-year-old example of the durability of concrete made with ash?

The correct answer:  The Pantheon. The Pantheon was constructed using volcanic ash, which has mechanical and chemical properties similar to coal ash. Its most famous feature is a 142-foot high dome with a central opening at its peak. After nearly 19 centuries, it remains the world's largest unreinforced concrete dome and a testament to the durability of concrete containing ash.

Congratulations, Toni!
