Part 11 -Environmental Community Monitoring Plan 133-135 Greenwich & 21-23 Thames Streets Airtek Project 05-0701— Rev 2 September 16, 2005

1.0 OVERVIEW

The Quality Assurance Project Plan (QAPP) documents the methods and procedures for the Environmental Air Monitoring and waste characterization operations during the deconstruction and demolition activities at 133-135 Greenwich Street & 21-23 Thames Street (the Site) are implemented and assessed with respect to quality.

The Environmental Community Air Monitoring Plan (ECAMP), Health and Safety Plan (HASP), and Waste Management Plan which are used in conjunction with this QAPP, contain specifics about the numbers and types of samples to be collected, decontamination procedures, sampling procedures, and all field activities to be performed during this program.

The Airtek Industrial Hygiene Staff are assigned the responsibility of taking many environmental samples in support of our clients.

In order to use data gathered during sampling and analysis information about the samples must be tracked methodically. Sample tracking systems integrate all data and records that relate to one sample, from the field logs to the final analytical laboratory reports. Sample tracking provides a mechanism for Airtek personnel to determine the ongoing status of a given sample.

2.0 SAMPLE TRACKING DATA MANAGEMENT Information gathering and tracking begins before the sample is taken and is completed when the final laboratory analysis results are accepted by Airtek. When information concerning a sample is obtained, it is entered into an electronic database. This information is available for review, generation of reports, or trend analysis. This procedure addresses the following activities and applies to all environmental samples collected as part of Airtek sampling programs: • Sample initiation • Chain of custody • Sample tracking • Collection input • Lab analysis/data input • Data review • Record keeping

2.1. Definitions Chain-of- Custody Form (COC): A document that follows the sample from the point of assembly through sample shipment to final disposition. Custody of the sample is indicated on the document by signature and dates of possession. Composite Collection Form: The document used by the Sample Collection staff to record field notes regarding composites. This form contains information about the composite which may not be given to the analytical laboratories such as site location, total sample
