Contract Compliance Screening System (CCSS) is designed to automate the determination of contractual compliance and completeness of data submitted to the EPA under the Routine Analytical Services (RAS) programs of CERCLA (Comprehensive Emergency Response Clean-up and Liability Act) and SARA (Superfund Amendments and Reauthorization Act). In order to remain consistent with the mainframe system the PC version of CCSS is written in SAS, and requires that SAS/PC be installed on the host PC. It will load analytical data from diskettes into SAS file format, perform technical edits on the data, produce technical defect and summary reports, and reproduce forms which contain defects. In addition, CCSS includes software to detect critical structural defects in the data format to assist in identifying these for correction prior to performing technical edits. Software Description: The software is written in SAS, MS/DOS Batch for implementation on an IBM AT, PS/2 or compatible computer using the MS-DOS 3.3 operating system. 2048K of RAM and 10 MB of disk space is required.
