Part III — Health & Safety Plan 133-135 Greenwich Street/21-23 Thames Street Airtek Project 05-0701— Rev 3, August 29, 2005

1.0 INTRODUCTION

This Health and Safety Plan (HASP) presents the practices and procedures that the Contractor shall implement and enforce during the deconstruction and demolition of the buildings located at 133-135 Greenwich/21-23 Thames Street in New York City (the Buildings). This HASP will be applicable to all persons entering the Buildings and to all persons working in and around the Buildings. The deconstruction of the Buildings will occur in two phases:

The Abatement Phase of the Deconstruction Project will occur while the work area is placed under negative pressure containment and includes the following general categories: (a) the general area cleanup of WTC dust and debris, (b) removal and disposal of installed porous and certain non-porous building materials and components, (c) cleaning and salvage of certain installed non-porous building equipment and components, (d) removal of building materials containing asbestos which were present in the Building prior to September 11, 2001 (referred to herein as "ACBM"), primarily within the Building interior, (e) packaging of asbestos and other regulated waste at generation points, movement of containers to the decontamination unit and movement of decontaminated containers to waste loading.

The Deconstruction Phase of the Deconstruction Project will occur following the Abatement Phase and removal all porous and contaminated materials, and will follow conventional demolition procedures. Deconstruction activities include the following general categories: (a) floor-by-floor deconstruction and removal of the remaining "clean" building components including exterior masonry walls, sub-flooring and structural wood frame components, and (b) general site work, including fencing, erecting scaffolding/hoists, paving, if any, and drainage. Summaries of the potential physical, chemical and biological hazards that may be encountered during these tasks and the associated hazard control methods are presented in Table 2-1.

The clean-up and abatement will be conducted so that the Building can be safely deconstructed in compliance with applicable law to allow for redevelopment of the site.

The Contractor shall be supported on this project by the Owner's Environmental Consultant who will provide environmental testing, air sampling and asbestos project monitoring and serve the function of Environmental Consultant/Project Monitor.

1.1 BACKGROUND

The events of September 11, 2001, which caused the destruction of the WTC Towers generated massive debris and dust. While not physically damaged, some of this WTC dust entered into the 133-135 Greenwich/21-23 Thames Street Buildings. The Buildings had been partially reoccupied after September 11, 2001 following clearance of debris and unspecified cleaning to permit re- occupancy.
