This authorization shall be valid for a period of six (6) months and if said cemetery company has not begun operations within that time, shall become null and void. Provisions for an additional period of not to exceed six (6) months may be obtained upon written application to the Commissioner, showing good cause for extension. The six (6) months authorization or additional period, shall begin as of the date the Commissioner issues the certificate of authorization or the extension of this authorization.
