Proprietors of official testing stations for which permits have been issued prior to the effective date of this Act may renew such permits for the renewal fee of $50 on the expiration of each 12 months following issuance of such permits, by complying with the requirements set forth in this Section. However, any city, village or incorporated town shall upon application to the Department and without payment of any fee or filing of any bond, but upon proof of experience, training and ability of the operator of the testing equipment, and proof of approved testing equipment as defined in Section 13-102, be issued a permit to operate such testing station as an Official Testing Station under this Act. The permit so issued shall at all times be displayed in a prominent place in the official testing station which is licensed as an Official Testing Station under this Act. No person or company or municipality shall in any manner claim or represent himself or itself to be an official testing station unless a permit has been issued to him or it as provided in this Section.
Any person or municipality who or which has received a permit under this Section may test his or its own second division vehicles and issue certificates of safety and conduct emission inspections of his or its own second division vehicles in accordance with the requirements of Section 13-109.1 with respect to any such second division vehicles owned, operated or controlled by him or it.
Each such permit issued by the Department shall state on its face the location of the official testing station to be operated under the permit and safety tests shall be made only at such location. However, the Department may, upon application, authorize a change in the location of the official testing station and the removal of the testing equipment to the new location. Upon approval of such application, the Department shall issue an endorsement which the applicant shall affix to his permit. Such endorsement constitutes authority for the applicant to make such change in location and to remove his testing equipment at the times and to the places stated in the endorsement.
