The practice of utilities selling coal ash byproducts is not unusual. The Tennessee Valley Authority (TVA) recently released a report stating that it sells about a third of the 7 million tons of fly ash, bottom ash, gypsum and boiler slag generated in its plants each year. Those byproducts have been mixed into concrete for roads in bridges and in blocks for buildings. The gypsum has been used in wallboard, granules for roofing shingles and grit for sandblasters. The byproducts even have been used as filler material for recreation areas, ball fields and industrial parks, according to the Atlanta Journal Constitution.

Yes, this is the same type of toxic material that spilled on to 300 acres of rural east Tennessee last December when one of the utility’s coal ash ponds failed, destroying nearby homes and causing hundreds of millions of damage to property. Environmentalists say the damage to wildlife and plant life is still to be determined, and many locals who live near the site have already suffered health problems. The coal ash contains toxins such as arsenic, lead, chromium, manganese and barium, which have been associated with serious health problems such as cancer, liver damage and neurological complications.

So it comes as little surprise that the Chinese drywall containing coal ash byproducts is also making people sick. The lawsuit alleges that the drywall emits one of several sulfur compounds giving homes made of it a foul odor. Some say those fumes also may cause respiratory health problems, headaches, dry eyes and nosebleeds. The long term affects of exposure are yet to be determined.

Other problems caused by the Chinese drywall include corrosion of air condition coils, putting homes at serious risk for electrical fires.

The class action lawsuit names the Knauf Group, PKT’s parent company; Banner Supply, a Miami-based materials supply company; and Rothchilt International, Ltd. , an export company in China. Legal experts believe many more lawsuits will follow.

TVA reported that it sells about a third of the 7 million tons of toxic material it generates at its coal plants each year. Those who purchase the coal byproducts say using it can reduce cost and improve quality of concrete.

However, critics worry about the safety of coal ash in the environment. Coal ash contains dangerous toxins, including arsenic, lead, chromium, manganese and barium. Those materials carry potential health problems such as cancer, liver damage and neurological complications, which has heightened concerns of environmentalists and those living in the east Tennessee neighborhood where the spill occurred.

A TVA marketing spokesperson says that up to 70 percent of coal ash is made up of silica, or sand. Twenty percent is aluminum compounds and the remaining 10 percent is sulfur and iron, arguing that the toxicity is minimal and in such small concentrations that it should not be harmful. Mike McDonald with the American Coal Ash Association added that coal ash “is about as toxic as dirt.”

A congressional committee meets this week to discuss federal regulation of coal byproducts.
