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 word
combinations and acronyms submitted by sources throughout the Agency. The
guide is intended to serve as a routine reference for the EPA 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, the postal abbreviations and the chemical elements.
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-15, Research Triangle Park,
North Carolina 27711, (919) 541-5369 or (FTS) 629-5369.
