SLANG
The Selected Letter and Abbreviated Name Guide (SLANG) is primarily 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.
Also, this guide contains some words related to subject matter rather than
letters. The use of this language in government work increases daily.
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 Agency personnel.
This Selected Letter and Abbreviated Name Guide (SLANG) contains words
submitted by the following sources: the Office of Administration (OA), the
Office of Air and Radiation (OAR), the Office of Research and Development (ORD)
and the American Federation of Government Employees (AFGE) - Local 3347.
The guide is intended to serve as a routine reference for the 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 miscel-
laneous symbols and the postal 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 Abramson, EPA, MD-14, Research Triangle Park,
North Carolina 27711, (919) 541-5694.

ENVIRONMENTAL ARGOT
Slang 1s not the sort of thing
To add into one's phrases.
And acronyms are not like hymns,
For no one sings their praises.
Maligned and scorned,'these letters torn
From fevered imaginations
•f
Perplex, confuse, confound, contuse
And cause heart pal pi tations.'.
Gary MeCutehen
