UPDATES

Several existing CIS databases were updated in November.

CERCLIS (Superfund Sites):

The number of sites/ records in the CERCLIS database increased from 45,941 to 46,230. The number of records with lists of PRPs attached (Potentially Responsible Parties) increased from 3,026 to 3,093.

RTECSŽ:

A regular quarterly update to the RTECS (R) database increased the number of records in the database from to 161,227 to 161,630, each dealing with one chemical substance. This is the fourth update performed on this database since November, 2004.

TSCAINV:

The TSCAINV database of chemicals listed on the public portion of EPA's TSCA Inventory -- the list of chemicals approved for use in industry and commerce in the US -- was updated in November. This update includes the 65,428 records drawn from the "second issue, 2005" of the database. (For a detailed discussion of the TSCAINV database, see the April 2004 issue of The CIS News. It is available in the newsletter archive at http://www.nisc.com/cis/cis_news.htm.)

FINDS:

The FINDS database of sites and facilities regulated under a wide variety of EPA and some state programs increased in size from 1,295,887 to 1,801,370 records.


OTHER DATABASES:

The IRIS and MALLIN databases also were expanded modestly in the course of the recent update.

USING THE "BACK" BUTTON

Until recently, CIS was set up so that you had to use the "Return to Search" button to get back from a results page to the search page. Using the BACK button in the upper-left corner of your browser did not work. This was because CIS was housed in a multi-frame set-up: The display actually included several different "frames" -- or images -- on the screen, and the browser's BACK button wouldn't function against all of these. Of course this was done because there were some real advantages to a multi-frame display, but the fact that the BACK button didn't work was a real nuisance to some users, who just could not get used to it. Consequently, we now have created a frameless version of CIS in which the BACK button does indeed work. If you'd like to have your CIS account switched to this set-up, send an e-mail to support@nisc.com. Note that this switch to the new interface won't be done UNLESS YOU ASK FOR IT. MAC users please note: The new set-up resolves all problems with Safari. If you'd prefer to use that browser with your CIS account, you'll have to request the change noted above.
