 PART 3 - DAS SPECIFICATIONS 

A. FEDERAL REGULATORY REQUIREMENTS 

1. The DAS shall comply with US EPA 40CFR60, 40 CFR75, State of [Insert State]Regulations, and any other requirements of the attached permit.  

B. DATA ACQUISITION SYSTEM 

            1.The DAS shall provide for automatic data acquisition, data processing, report generation, graphical display of data, printing and/or storing reports in electronic format, email transmission of reports and alarms, archival storage of data, and providing remote access to the system via network connection or modem. 

            2.  The system shall be utilize Windows 2000â as the operating system. No hybrid Unix/Windows systems will be considered. The Data Acquisition System (DAS) shall be designed from the ground up as a Windows application taking full advantage of the inherent connectivity allowed by ODBC compliant applications. The DAS must be designed around a well proven, commercially available, Database. The report generator shall also be a commercially available, user accessible product.
