(a) Any unauthorized release from the primary containment which the operator is able to clean up within eight hours and which does not escape from the secondary containment does not increase the hazard of fire or explosion and does not cause any deterioration of the secondary containment of the underground storage tank shall be recorded on the operator's monitoring reports.
(b) Any unauthorized release which escapes from the secondary containment, increases the hazard of fire or explosion, or causes any deterioration of the secondary containment of the underground tank shall be reported by the operator of the permitting authority within twenty-four hours after the release has been detected or should have been detected. A full written report shall be transmitted by the owner or operator of the underground storage tanks within five working days of the occurrence of the release.
(c) The permitting authority shall review the permit whenever there has been an unauthorized release or when it determines that the underground storage tank is unsafe. In determining whether to modify or terminate the permit, the permitting authority shall consider the age of the tank, the methods of containment, the methods of monitoring, the feasibility of any required repairs, the concentration of the hazardous substances stored in the tank, the severity of potential unauthorized releases, and the suitability of any other long-term preventive measures which would meet the requirements of this chapter. (Ord. No. 1043, § 1 (part).)
