3.0 Purpose and Objectives of Current Investigation

DASNY/CUNY is committed to ensuring that appropriate safeguards are put in place at 30 West Broadway during the deconstruction process to protect workers and to prevent release of the contaminants that may be present into the surrounding community and the environment. The Characterization Study was conducted as the first step in the remediation and deconstruction process for this building.

An Asbestos Building Inspection and Material Survey was required to facilitate the proposed deconstruction of the Building and to comply with: (1) the New York City Department of Buildings (NYC DOB) permitting requirements, and (2) the pre-demolition requirements promulgated by the New York City Department of Environmental Protection (NYCDEP), Section 1-53; the New York State Department of Labor (NYSDOL) Industrial Code, Rule 56: Asbestos Regulation, Title 15, Sections 56-1.4 and 56-1.9(e); and the U.S. EPA National Emissions Standards for Hazardous Air Pollutants (NESHAP) for asbestos-containing materials (ACM).

In addition to the asbestos survey, the specific objectives of this Characterization Study include:

• Conducting monitoring of the impact to the outside environment of entry to the building (per NYS DOL approved variance); • Gathering the necessary exposure data related to the types and levels of air contaminants present prior to building cleaning and deconstruction that may be encountered by workers carrying out activities at the site during deconstruction and Providing data that may be applied to choosing the appropriate levels of worker protection at the site; • Determining the physical and environmental condition of the facade and its components, as the facade an integral part of the engineering control systems is

that will be used to safeguard the surrounding community and the environment; • Providing pre-demolition background data for the site and surrounding environment;
