When renewing a permit the Minister may take into account the public interest factors referred to in the fourth paragraph of section 10 and change any condition or restriction imposed at the time the permit was issued or impose any necessary condition or restriction that he determines. He shall indicate such change, condition or restriction on the permit.
The Minister may, however, issue a permit for a shorter period if he considers it required in the public interest taking into account the factors referred to in the fourth paragraph of section 10 or in the cases prescribed by regulation.
