NYC 9/11 Public Portal Document

A data analysis report will be submitted to Contractor at the end of the program. Data will be stored in a central database in a standard foimat. The data analysis will review the meteorological, PM, PAH’s, PCB, and D/Fs data.

The data collected during the demolition segment of the monitoring program will be primarily used for real-time data display and triggering notification when action levels are exceeded (See Sections 7 and 8). All continuous monitoring data will be archived in Microsoft SQL Server databases maintained on a secure Internet server in the Contractor Environmental Subcontractor’s offices.

Basic summary information and real-time displays of the monitoring data will be available interactively on-line. The Website will allow the Contractor Environmental Subcontractor personnel to interactively view the monitoring data via charts, maps, or tables. Reports viewed in tabular format on the Web can also be saved to Excel spreadsheets. Additional required information, such as daily calibration information and wind roses, will also be available on the website.

Authorized personnel from USEPA Region 2, NYCDEC, NYSDEC and NYSDOL will also be provided direct access to the website where all air monitoring data will be posted. In addition, once the air monitoring data has been subject to QA/QC review validated results will also be posted on the website in a dedicated location for direct access by the general public.

11.3.1 Electronic Communication Equipment and Software

As previously described, communications with the CSI data loggers will be via cellular CDMA modems at each station. The loggers will be polled automatically from Contractor Environmental Subcontractor’s office and the retrieved data will be automatically uploaded immediately after receipt. Data can be downloaded by users directly to Microsoft® Excel® or Access®.
