Beginning on January 1, 2024, the Boiler and Pressure Vessel Safety Program will require licensees to use the online application system to apply for all licenses, exams and renewals. Using the online system allows staff to process applications more quickly and efficiently. This will decrease wait times and will allow applicants to track the status of their applications.

As a result of this change, after January 1, 2024, applications received by fax, mail or email will not be processed and will not be returned to the applicant.
