The statute calls for the certificate to be issued by the local unit for the number of years it designates. The PTD staff determines the ending date by the language in the resolution. Once the certificate is issued, the ending date can only be changed when one of the following applies:

1. STC Rule 53 which provides for an extension of time to complete the project.
2. Section 7a of the Act which applies to facilities which exceed $150,000,000 of SEV.
3. Section 16a of the Act which applies to certificates effective after 12-31-95 for which the exemption period is shorter than the maximum allowed under section 16.
