Welcome to the Terminology Reference System

TRS Logo

 

TRS Transitioning to the Environmental Terminology System and Services: EPA is phasing in a new terminology management system and offering associated services which will enable Agency programs to create glossaries, thesauri, taxonomies and keywords for drop down menus. The ETSS is available to developers of terminology now (for login and training information, contact the ETSS Administrator) and will be available to the public for search and retrieval by the end of 2007. Until the ETSS Search and Retrieve functionality is available to the public, the TRS will continue to provide access to Agency terminology.

The Terminology Reference System (TRS) has been created as a single resource of environmental terminology for the Agency by compiling collections of terms from EPA and other sources.

Click on a letter/number below to retrieve a list of all terms beginning with that letter or number. Other ways to query TRS information may be found on the Search page.
