What to Do if a Chemical Is Not on the List
If you cannot find a listing for a particular constituent, that
does not mean a health-effects evaluation is not required.
Please contact the Toxicology Section staff to find out if a
screening level has been established for a constituent or to be
sure of the most current screening level. If no screening level
exists for the constituent, then all customers must complete the
TCEQ Effects Screening Level Derivation Request Form and submit
it to the Toxicology Section staff. However, before you begin
completing this form, check synonyms and Chemical Abstract Service
Registry numbers (CAS Nos.) to make sure the constituent is in fact
not listed in our list of screening levels.
