Section 2 - Ambient Air Monitoring Program Revision No.: 0 130 Liberty Street Deconstruction Plan Date: September 7, 2005 Lower Manhattan Development Corporation

5.0 SAMPLING AND ANALYSES METHODOLOGY A summary of all sampling and analyses methods proposed for use during the deconstruction of 130 Liberty Street is provided in Table 2. All analytes will be measured at Locations 1-5 identified in Table 1 during the Background Phase. All analytes will be measured at each of the stations identified in Section 2.0 of this plan during Phase I and Phase II. These phases as defined in Section 3.0 of this plan include background monitoring (2 weeks prior to Phase I), Phase I - Preparation Phase, Phase I - Asbestos and COPC Abatement, and Phase II - Structural Deconstruction. As noted, all samples in Table 2 will be collected over 24-hour integrated time periods with the exception of asbestos, silica, real-time PMm and PM2.5, and mercury vapor employing the Lumex device. Asbestos and silica samples will be collected over 8 hour averaging periods, while PMm and PVL . measurements will be collected on a continuous near “real time” basis. Proper chain of custody procedures will be employed for all intregrated samples collected. Details regarding the sampling and analyses methods planned for each type of target parameter is provided in the following sections.
