| Abstract |
This report describes modification, content expansion and update activities performed on the Organic Chemical Producers Data Base (OCPDB), an EPA-owned, computerized information system containing data on chemical products and industrial production facilities located in the United States. A brief description is given of the OCPDB system structure as implemented under System 2000, the data base management system currently used for the revision, update and maintenance of the OCPDB. A discussion of OCPDB data is presented, describing the types of information available in this data base. Revisions to the OCPDB scheme made to facilitate the incorporation of additional information are described, and a newly-developed data report for chemical uses is illustrated. Content expansion, verification and update activities for all data are discussed in detail, and appropriate reference material is cited specifically for each component of data. A recommended, stepwise procedure for incorporation of the OCPDB as an individual component of the EPA/NIH Chemical Information System is presented, along with recommendations to expand the scope of information and improve the utility of the data base. Examples of all OCPDB standard reports are illustrated and a listing of chemicals and producers comprising the OCPDB is presented. |
