A new environmental study finds high levels of contamination at the Deutsche Bank building across the street from the World Trade Center site, which is slated for demolition.

The report, released at a public hearing Tuesday night, said the 40-story building, which was heavily damaged in the September 11 attacks, contains dangerous levels of asbestos, dioxin, lead and other contaminants.

An independent company conducted the study for the Lower Manhattan Development Corporation, which bought the building last month and plans to begin razing it by the end of the year.

A one-month public comment period on the demolition opened Tuesday with a public hearing at the office of Assemblyman Sheldon Silver. Local residents voiced concerns about asbestos and the effects of daytime construction work.

Rebuilding officials said they will consult with environmental experts throughout the demolition process.

Before the Deutsche building, which was heavily damaged in the September 11, 2001, attacks, can come down, the plan must be approved by local and federal agencies, including the Environmental Protection Agency

An open informational meeting is scheduled for next Thursday. For more information on that meeting, or to make a public comment, go to the Lower Manhattan Development Corporation’s website at www.renewnyc.com.
