The Selected Letter and Abbreviated Name Guide (SLANG)
Is a compilation of word combinations and acronyms. Word
combinations and acronyms are words usually formed from the
first, or first few letters of several words. However,
this guide contains some words related to subject matter
rather than letters. The use of this language In govern-
ment work Increases dally. Newcomers to the government
working force, the nongovernment public, and even some
longtime Federal workers are occasionally lost In grasping
this jargon. To ease this situation, the Office of Air
Quality Planning and Standards (OAQPS) has printed a list
of words used most frequently by Environmental Protection
personnel In the Research Triangle area.
This Selected Letter and Abbreviated Name Guide (SLANG)
contains words submitted by the following sources: the
Office of Administration (OA), the Office of Air, Noise,
and Radiation (OANR), the Environmental Research Center
(ERC), and the American Federation of Government Employees
(AFGE) - Local 3347. The guide 1s Intended to serve as a
routine reference for the local EPA user community.
For the convenience of the user, the words with their
definitions are arranged In alphabetical order with the
exception of the Greek and miscellaneous symbols and the
postal state abbreviations. Ample space Is provided at the
end of each letter of the alphabet to allow for the addition
of new words or those "unavoidably omitted." In this
manner, new words will be readily Identified for use and
later Insertion Into a revised guide.
Additional words are solicited and can be placed In
future revisions of the booklet by contacting Betty G.
Abramson, EPA, MD-14, Research Triangle Park, North Carolina
27711, (919) 541-5694.

Neophytes to Internal technical jargon quickly be-
come lost In the alphabet soup that seems to have become
Ingrained In the American tongue*. Though efforts are
made to reduce or eliminate the use of such verbal coding
of Information, the practice seems to be endowed with
traits of survival that are destined to keep It off the
"endangered" species list for the foreseeable future.
This booklet attempts to assist those1"unenlightened"
persons who may be peering Into the Inner circles of
EPA's jargon so that they .may be better decode the "lan-
guage and enhance efforts to communicate.
