Texas Instruments, DS&EG - Dallas, TX
Texas Instruments (TI) DS&EG implemented their environmental database system (TIESYS) in 1990 in response to expanding government requirements in documentation on chemicals used by the company. TIESYS is an integrated database system that collects, tracks, and controls a variety of environmental data for supporting multi-disciplinary record keeping requirements. It also provides manufacturing and support management with timely and accurate data for operations analysis. Prior to 1985, the record keeping requirements of chemicals used by industry were limited to the control of all chemicals imported and exported as required by the Toxic Substance Control Act of 1977. Since 1985, environmental laws have placed an additional burden on the record keeping functions of industry such as:
- Knowledge of all chemicals in the plant (OSHA, 1985)
- Volumes and locations of chemical use (Superfund Amendment Reauthorization Act 311/312/313/, 1986)
- Mass balance/chemicals at process versus fate (Superfund Amendment Reauthorization Act 313, 1986)
- Document process throughput and improve-ments (Pollution Prevention Act, 1990)
- Know chemicals and quantities in emissions and stacks (Clean Air Act Amendment, 1990).
In 1990, TI DS&EG analyzed the condition of their environmental database system and concluded that they were no longer effectively managing the necessary operational tasks to meet the dynamic regulatory climate, increasing customer requirements, and quality issues. Therefore they initiated the TIESYS Project in March 1990.
The first phase of the project included forming a committee, generating requirements specifications, conducting a market analysis, interviews and plant visits, and purchasing Flow Gemini software from General Resource Corporation, Santa Barbara, CA. The second phase started in January 1991 with implementation of a pilot project at TI DS&EG's Lewisville, TX site. The Flow Gemini's System Interface was assembled and the Chemtrak package was developed in-house. The Inventory and Chemical Information Systems were available off the shelf.
TI DS&EG has realized a number of achievements including the ability to track chemical use down to the process level ability to store data on products and ingredients ability to compile data on all products ability to establish on-site quantities and the ability to compile and produce reports such as SARA 311/312. Although these achievements of the DS&EG database system are common among chemical manufacturing industries, it is unique among the chemical user industries and has generated a considerable interest from other industries.
With the success demonstrated on the pilot project, the next phases of the project will include migrating the system to a mainframe in January 1992 and fan out to other sites throughout 1992 and 1993.
