Oregon Revised Statutes Protection from Fire § 480.150

(1) The State Fire Marshal may adopt reasonable rules for granting permits for supervised public displays or sales of fireworks by municipalities, fair associations, amusement parks, and other persons, organizations or groups of individuals. The governing body of any municipality, or of any county, may require liability insurance, or an irrevocable letter of credit issued by an insured institution as defined in ORS 706.008 or other form of indemnity deemed adequate by the municipality, or the county, from any person, in a sum not less than $500, conditioned for payment of all damages which may be caused either to a person or property by reason of the authorized display or sale and arising from any acts of any person or agents, employees or subcontractors of the person. At the time a permit is revoked, the State Fire Marshal or approving authority may include in the revocation order a provision prohibiting the holder of the revoked permit from applying for or obtaining another such permit, for a period not to exceed three years from the revocation date, if the State Fire Marshal or approving authority finds that the circumstances of the permit holder's failure to comply with applicable sale or display statutes and regulations presented a significant fire hazard or other public safety danger.

(2) The State Fire Marshal or the approving authority of any governmental subdivision may revoke permits for display or sale of fireworks when in the opinion of the State Fire Marshal or the approving authority the sale or display of fireworks is not in compliance with applicable statutes and regulations governing such sale or displays.

(3) Permit fees required by ORS 480.130 shall not be refunded in the event such permits are revoked.
