A non-refundable fee of $150 shall accompany each application to the Commissioner of Labor to take the crane operator's exam. Such application and fee shall permit the applicant to take the exam on either of the next two available dates. Failure of the applicant to take the exam on those dates, or failure of the applicant to pass the exam, shall result in a forfeiture of the fee, and such applicant shall be required to submit a new application fee before being permitted to take the exam. Upon passing the exam, the application fee shall be applied towards the certificate of competence. A non-refundable fee of $60, payable to the Commissioner of Labor, shall accompany each triennial renewal of such certificate.
