EPA Publication Numbering System
The EPA publications numbering system was designed in 1991 to provide easier identification, tracking, and dissemination of publications. Each publication number identifies:
- The responsible organization producing the publication
- A specific office/division within the organization
- An alpha descriptor of the document type
- Calendar year in which the publication was produced
And the sequential number identifying how many of that type of publication were produced within that particular organization during the calendar year.
Example: 200-B-96-001 indicates a publication from Administration & Resources Management (see Table 1); a reference (see Table 2); produced in 1996; and the first publication of that type issued in the year.
