Notice:

Because it is out of date, TABLE4-1.ZIP has been removed from
this BBS. The file was excerpted from the July 1990 "NATICH
Data Base Report on State, Local, and EPA Air Toxics Activities",
and contained State and local Agency acceptable ambient concentration 
guidelines or standards. The document was revised in 1993, but no 
electronic copy is available. For more current information of this type, 
look on the NATICH BBS, elsewhere on the TTN. The NATICH BBS has a 
database which allows for searches by pollutant. This may be accessed 
from option <3> on the NATICH Main Menu.
