Three men and a demolition company were convicted by a federal jury in Chattanooga, of environmental crimes and obstruction of justice charges related to the illegal demolition of a Chattanooga factory containing large amounts of the toxic air pollutant asbestos.

David Wood, Donald Fillers, James Mathis, and Watkins Street Project, LLC, a business formed for the purpose of salvaging and demolishing the facility, were convicted today of conspiracy, Clean Air Act, and obstruction-related offenses.

Mathis was found not guilty of one of the Clean Air Act charges, but guilty of conspiracy and three other substantive Clean Air Act counts.

During the course of the three-week trial, the evidence proved that the defendants entered into a year-long scheme, from August 2004 to September 2005, in which the former Standard Coosa Thatcher Plant was illegally demolished while still containing large amounts of asbestos.

Any asbestos that was removed from the plant prior to demolition was removed illegally, scattered in open debris piles, and left exposed to the elements in the vicinity of the 1700 block of Watkins Street.

During the course of these illegal operations, visible emissions engulfed surrounding businesses, residences, and a day-care center, potentially exposing the surrounding community to substantial quantities of asbestos - a substance for which the U.S. Environmental Protection Agency has determined there is no safe-level given its demonstrated tendency to cause lung cancer, mesothelioma, and asbestosis.

The evidence also showed the defendants tried to cover up their illegal activities by falsifying documents and lying to federal authorities, prosecutors said.

Sentencing is set for June 7. The conspiracy and substantive Clean Air Act, and false statements counts of the indictment each carry a maximum possible term of five years in prison and a fine of $250,000, twice the gross gain to the defendants, or twice the gross loss to a victim.

The obstruction of justice charge carries a maximum possible term of incarceration of 20 years and similar fines.

U.S. Attorney Bill Killian said, "These convictions reflect the very serious nature of violating EPA requirements, especially when the violations involve exposing the public potentially to cancer and other diseases. The cooperative work of the federal and local agencies, along with the diligent work of AUSA Matt Morris and DOJ Attorney Todd Gleason and staff have resulted in these verdicts. This demonstrates to the public the commitment of the U.S. Attorney’s Offices to enforce and prosecute environmental violations of federal statutes.”

The case was investigated by special agents of the EPA's Criminal Investigation Division and investigators with Chattanooga-Hamilton County Air Pollution Control Bureau. The case was prosecuted by Assistant U.S. Attorney Matthew T. Morris and Todd W. Gleason, Environmental Crimes Section of the Environment and Natural Resources Division of the U.S. Department of Justice.
