Utilize the "^" (caret) character, accessed by hitting SHIFT 6 on your keyboard, to narrow your search to records that begin with a particular string. For example, using ^ACME will only return records that begin with the string "ACME". On the other hand, simply specifying ACME (without the caret) will return records that contain "ACME" anywhere within the string.

You only need to enter one field; leaving all fields blank will bring up the entire UST listing. Due to the size of the database, your wait may be up to several minutes.

UST List
The UST List is typically updated and published annually. The UST and LUST lists are derived from the same database used by ADEQ. If you are unable to find the facility you are searching for, it may be for one of the following reasons:

• The facility was not registered with ADEQ because the UST is exempt or was closed prior to implementation of the UST program in 1988.
• The UST was installed or registered very recently, or the LUST is a recent one.
• The selection criteria were not entered correctly.
