AQS Web Application Setup

An initial setup is required to use the Air Quality System (AQS) web application and CDX.  There are three steps detailed below.  After the initial setup, you may access AQS by following the link from the AQS Web page (see sidebar) or your own private bookmark (see recommendation in 1, below).

20 Nov 2006:  After the upgrade to the Oracle 10g R2 Application Server, AQS Web and AQS Discoverer Web use J2RE by default instead of JInitiator.  If you do not already have Java 2 Runtime Environment 5.0 installed, you will be prompted to install it (or to upgrade to it if you have an earlier version.)

Please read all instructions before beginning.  You may want to print this page before starting.

Setup:

  1. Install Sun Java Plug-in 
    If you already have version 5 or above installed, you will skip this step.  If you have an earlier version, you should be prompted to upgrade to this version.  If your agency requires it, your network administrator may have to install this. (Java version 5 is the preferred version. Some users have experienced problems with later versions of Java.)

    2. To begin setup, click the following URL Link: https://oasext.epa.gov/aqs (You may want to bookmark this page to use for direct access in the future. 

    With Microsoft Internet Explorer (version 7 is not recommended), you should see something similar to the following screen prompts:


    Choose "Install"


    Choose "Typical setup" and  "Accept"


    You do Not need to install the Google Desktop as part of AQS setup.  Click "Next"


    Click "Finish"

  2. Install the applet and logon to AQS
    (You may not see the next 2 screens, but you should see the logon screen.)


    "Yes" or "Always"


    Logon to AQS

  3. CDX Registration

    New AQS users who will be transfering files to or from AQS need to register on CDX.  You should receive an email advising you to call the helpdesk at 888-890-1995 to obtain your customer retrieval key. Your email will also provide the web address for completing your registration.  Use this link to access CDX Registration.  If you are asked to choose a role during the registration process, select the role of "submitter". 

    4. Once you have completed the CDX registration, close your browser and reopen it before attempting to use AQS and CDX.

If you need assistance accessing any of the material in AQS, User Support is provided through the Customer Call Center. The toll free number is 866-411-4EPA (866-411-4372).  Please contact them first with any questions about using the AQS application.
