Study: Dredged sediment dangerous

EAST CHICAGO — Because its own studies predict air emissions from a proposed facility that will store millions of cubic yards of contaminated muck will fall below current legal limits for air quality, the U.S. Army Corps of Engineers have not included a system to control such emissions.

As of now, the corps is simply not required under federal and state regulations to have a system in place to monitor levels of such deadly toxins as ammonia, cyanide, manganese, arsenic, lead and mercury once its proposed confined disposal facility (CDF) begins to accept contaminated sludge in two years.

The CDF will sit in close proximity to schools and neighborhoods in East Chicago and Whiting.

However, a new study conducted by Northwestern University for the Chicago Law Clinic at the Chicago-Kent College of Law takes aim at the corps’ stance of not having such monitoring equipment, citing the health risks to residents, especially children.

“There are serious questions about the safety of the nearby children who themselves represent an at-risk population for asthma and other respiratory ailments,” the study states. “The 30-year time period that will elapse before air emissions are finally controlled will have consequences for at least three generations of children.”

The study was performed by Todd Waldrop, a graduate student of Northwestern University’s Department of Environmental Engineering in the fall.

Waldrop said the Corps estimates are based on a model used to determine chemical losses from soils that received petroleum wastes in a land-farming process, not for CDFs.

“I think the study is very good. All (Waldrop) did was look at one part (of the project), air emissions,” said Betty Balanoff, a vocal CDF opponent who contacted the Chicago Law Clinic to do the study.

Christine Brooks, who sits on the East Chicago Waterway Management Board, said she has not fully examined the study.

Brooks said there are some monitors already in place, including at nearby East Chicago Central High School, that monitors the air quality.

Bill White, the Army Corps’ project manager for the CDF project, says the Corps is developing more refined plans in how it will handle the sediment.

The CDF will be built on 134 acres of land once owned by Energy Cooperative Industries of East Chicago at the northwest side of Indianapolis Boulevard and the bridge of the Indiana Harbor and Ship Canal.

The canal was last dredged in 1972 and the build up of sediment has made navigation difficult for cargo ships.

While most agree the canal must be dredged, there has been much debate as to the safety of storing such contaminants close to neighborhoods.

The project is led by the Army Corps, with the U.S. Environmental Protection Agency, the Indiana Department of Environmental Management and the East Chicago Waterway Management District major participants.

Once dredging begins in 2005, it will continue for some 30 years before it is to be capped.
