1. Reinventing Chemical Information Management at the Environmental Protection Agency (EPA) Presented to the Chemical Information Division American Chemical Society March 30, 2000 Lois E. Fritts, Tommie G. Curtis Scientific Applications International Corporation SDC-0002-021-LF- 2043

3. SDC-0002-021-LF- 2043 EPA Formed in 1970 Single independent regulatory authority formed from federal organizations including: Department of Interior Food and Drug Administration Health Education and Welfare Department of Agriculture Atomic Energy Commission Council of Environmental Quality

4. SDC-0002-021-LF- 2043 EPA Legislative Authority 1970 --CAA 1972 -- NEPA 1972 --CWA 1972 --FIFRA 1972 -- ODA 1974 --SDWA 1976 --TSCA 1976 --RCRA 1976 --ERDDA 1980 --CERCLA 1986 --EPCRA 1990 --PPA

5. SDC-0002-021-LF- 2043 Chemical Information Management Problems EPA formed from many separate organizations EPA programs funded independently by Congress No EPA standards to ensure consistent identification of chemical substances and groupings

6. SDC-0002-021-LF- 2043 Chemical Data Problems Chemical substances are identified and represented inconsistently in Agency data systems and in environmental regulations EPA is interested in chemical classes and categories that have not been registered by Chemical Abstracts Service (CAS) CAS Registry Numbers are not always validated or used appropriately

7. SDC-0002-021-LF- 2043 Lindane Identifiers Hazardous Waste Codes D013 U129 Parameter Codes 34266 39340 39782 CAS Registry Numbers 58899 000058899 58-89-9 Pollutant Codes HCCH

8. SDC-0002-021-LF- 2043 Lindane Names R-BHC (Lindane) gamma gamma-BHC BHC-gamma Lindane 1,2,3,4,5,6-Hexachlorocyclohexane, gamma Benzene hexachloride, gamma

9. SDC-0002-021-LF- 2043 Interim Attempts to Resolve Problems 1986 - EPA CAS Registry Number Data Standard Required CAS Registry Number for all data records about chemical substances 1994 - Envirofacts Master Chemical Integrator (EMCI) Provided a cross reference to chemical identifiers across EPA data systems

10. SDC-0002-021-LF- 2043 More is Needed EPA CAS Registry Number Data Standard does not go far enough to establish accuracy and consistency EMCI is limited to the data systems in the Envirofacts warehouse; it does not address the scope of Agency needs for integrated data sharing

11. SDC-0002-021-LF- 2043 Reinventing Environmental Information (REI) Program 1995 - Need for standards to represent key identifiers in six essential areas: Date Facility Latitude/longitude Business classifications Biological taxonomy Chemical identification

12. SDC-0002-021-LF- 2043 Data Standards Process Establish workgroups of knowledgeable EPA staff Define exact data requirements for the standard Determine business rules for implementation Record data elements and rules in the EPA Environmental Data Registry (EDR)

13. SDC-0002-021-LF- 2043 Interim Chemical Identification Data Standard CAS Registry Number CAS systematic chemical name (preferably using 9th CI nomenclature) EPA Chemical Registry Name EPA Identification Number for groupings of chemicals of interest to the Agency

14. SDC-0002-021-LF- 2043 Optional Data Elements for Chemical Identification Molecular formula Molecular weight Sources of chemical names and synonyms Linear structural formula Graphic structural formula Definition, to further explain Comments, to add information

15. SDC-0002-021-LF- 2043 Business Rules for Implementation Overview of the standard Definitions Applicability Data requirements Processing Roles and responsibilities Implementation Maintenance

16. SDC-0002-021-LF- 2043 Special Requirements Determine the EPA Chemical Registry Name Establish a central EPA Chemical Registry System (CRS) to support the standard www.epa.gov/crs/
