The objective of this project is to develop, test, and apply a user interface tool for collecting authorized emissions and actual hourly emissions data for subsequent upload into the State of Texas Air Reporting System (STARS). The project has three main tasks:

Task 1: Software Development, Documentation, and Testing
URS will develop and test a user-friendly interface tool for companies to report authorized emissions data and special hourly emissions inventory data to TCEQ. In performing this task, URS software developers will interact closely with TCEQ staff to obtain input to the design and development process and to facilitate potential future use or modification of the software by TCEQ staff. URS will also seek input from industry representatives during the software design phase of this task on ways to simplify the data collection process without reducing the quality or quantity of the required data. After development is complete, URS will test the input and STARS-upload features of the interface tool.

Task 2: Data Collection
URS will apply the user interface tool by collecting emissions inventory and permit data from selected emissions inventory accounts as specified by TCEQ. URS will request hourly routine, event, start-up, shutdown, and maintenance emissions from specific EPN/FIN paths selected by TCEQ for the period, May 1, 2005 – June 30, 2005. URS will also request current permit allowable emissions for those same sources.

Task 3. Quality Assurance and Reporting
URS will quality assure the collected emission inventory and permit data by:
1. Assessing data completeness;
2. Verifying that EPN/FIN names have not been changed;
3. Checking that the reported emissions data are hourly-specific;
4. Verifying that the emissions data are reported as distinct chemical compounds/species and not reported as "unspecified" or "unknown";
5. Verifying that each emissions sources' reported emissions are logical and match the source type (for example, if an account reports VOC process emissions controlled by a flare, the VOC emissions are reported at the process FIN/ flare EPN path, whereas the combustion emissions are reported at the flare FIN/ flare EPN path);
6. Verifying that the reported emissions data were determined using the best available data (such as CEMS, PEMS, or source testing); and
7. Compare reported hourly emissions with authorized hourly emissions.
