Attorneys for Lycoming Construction Services, LLC, a Williamsport, Pennsylvania-based limited liability company, entered a corporate guilty plea Thursday before Chief U.S. District Court Judge William M. Skretny in Buffalo to a violation of the federal Clean Air Act for inadequate asbestos removal work in the demolition of the Dahlstrom industrial complex on Buffalo Street in Jamestown.

U.S. Attorney William J. Hochul, Jr., said the firm faces a fine up to $500,000 or a term barring it from federal work for five years when sentenced Aug. 13.

As a result of an investigation by special agents of the U.S. Environmental Protection Agency’s criminal division, the company admitted that in the demolition work from January 2012 until last November its employees removed regulated asbestos containing material from one of the condemned buildings in the complex without adequately wetting it, in violation of Clean Air Act work practices mandates.

The demolition involved a cluster of condemned building on either side of the Chadakoin River, with the illegal removal work being done in one of the buildings on Buffalo Street.
