Air Sampling and Monitoring Protocol Site: 130 Cedar Street Prepared for Masterworks Development 1.0 Introduction

JLC Environmental Consultants, Inc. (JLC) has been retained by Masterworks Development Corp. to prepare this proposed air-sampling plan for abatement/ deconstruction work at 130 Cedar Street, New York, New York (hereby known as "the subject property"). This plan encompasses several types of monitoring that correspond with the complex nature of the deconstruction process. The demolition includes asbestos and lead based paint removal, roof and exterior façade renovation and interior construction. Source documents used for reference herein are listed in the footnotes and the attached Appendix A. The following is a brief summary of the basic types of sampling work to be completed at the subject property. These definitions were outlined In the Proposed Ambient Air Monitoring Program for the 130 Liberty Street Deconstruction Project: Level 1: The personnel performing deconstruction work will be responsible to collect personal air samples representative of LC .r 1tl; various work activities. The purpose of this sampling is to determine airborne levels of contaminants generated at the source point. Level 2 iill collect ambient air samples and wipe samples inside the building during deconstruction and abatement of known hazards. Sampling will also be conducted outside the isolation • barriers of the work area and at exits points from contaminated spaces (i.e. the personnel and waste load out decontamination units). Level 3: JLC will monitor the exterior ambient air of the site at street level. — Level 4: JLC will monitor at various points outside of the project boundary. Concurrent comprehensive meteorological monitoring to assist in data analysis will support this sampling.

2.0 Background

This proposed program has been developed to monitor for contaminants of potential concern (CPOC) as referenced by the Initial Building Characterization Study Reps prepared for a neighboring building located at 130 Liberty Street. Meetings and discussions with personnel from the United States Environmental Protection Agency (USEPA) and the New York City Department of Environmental protection (NYCDEP) were also helpful in preparing this document as was the 'Proposed Ambient Air Monitoring Program for the 130 Ubmty Sweet Decons*zucuon Project, prepared by Weston Sohrtiom, Inc., revision 12/1012004
