If you are UST certified or licensed in another state or with a federal regulatory program, you may be eligible for UST professional licensure in Iowa without having to take a course of instruction or pass an examination, pursuant to Iowa Administrative Code 134.19(6)c. The Iowa UST Section may approve certain state or federal regulatory programs for reciprocity. To find out if your license or certification is approved for reciprocity, please reach out to email@example.com.
If approved for reciprocity, you will need to submit an initial licensing application with additional required supporting documentation, pay a $200 licensing fee, and also be licensed under an Iowa UST Professional Licensed company. Once licensed in Iowa, all professionals are required to comply with Iowa UST regulations and license renewal requirements.
