Talk about bad ideas. Kansas City is on a short list to store all of the nation's waste mercury - about 10,000 tons of it. A new law mandates that the mercury have a home by 2013.

But not in the city at the former AlliedSignal plant on Bannister Road. Have the smart folks in Washington, D.C., been to Kansas City?

This isn't Yucca Mountain in Nevada, where federal officials want to dump radioactive waste.

A lot of people live near the Bannister Road complex, and mercury is not a harmless, playful metalic substance.

It is highly toxic. It can evaporate into the air at room temperature. Mercury vapor can cause headaches, coughing, chest pains and permanent lung scarring. Mercury can cause memory loss, personality changes and loss of intelligence.

Other sites being considered are the Grand Junction Disposal Site in Colorado, Hanford Site in Washington state, Hawthorne Army Depot in Nevada, the Idaho National Laboratory in Idaho, Savannah River Site in South Carolina and Waste Control Specialists in Texas.

The Bannister complex has enough problems with such cancer-causing materials as beryllium, radiation waste and PCBs left behind as waste from its Cold War nuclear weapons component production days.

A hearing is set for July 23 at the Embassy Suites, 220 W. 43rd St. Let's hope a lot of people show up and shoot down this dumb idea.
