FILE - In this Dec. 22, 2008, photo, a home is engulfed near Tennessee Vally Authority's Kingston Fossil Plant after the failure of a storage cell unleashed 5.4 million cubic yards of ash sludge near Kingston, Tenn. The Tennessee Valley Authority is defending its relationship with a contractor accused of subverting safety precautions and sickening workers during the cleanup of the massive coal ash spill. In a letter this week, TVA President and CEO Bill Johnson said that to TVA's knowledge, Jacobs Engineering Group "did not have a history of safety lawsuits or test tampering." He also said TVA is unaware of complaints to the utility being mishandled. A lawsuit claims Jacobs' negligence is to blame for the deaths of more than 40 workers and illness of more than 400 others.
