        36.   Underground tanks must be double walled and have an interstitial space between
              the two (2) walls of the tanks that is capable of being monitored for any breach
              of either the inner or outer wall of the tank.
        37.   All tanks are to meet the requirements of UL 1316 Glass fibre reinforced
              underground storage tanks for petroleum products, alcohols and alcohol gasoline
              mixtures or the equivalent.
        38.   A Certificate of Compliance must be provided by the manufacturer of the tanks
              to Council prior to the commissioning of the tanks for service.
        39.   An overfill protection valve must be installed in the drop tube of the tank and
              calibrated to prevent the tank from being filled in excess of 90% of its capacity.
              An overfill alarm must be installed to visually and audibly alert persons in the
              vicinity of the tank.
              Leak Detection UPSS
        40.   The leak detection system of the UPSS must:
              a.   detect a leak from any portion of the underground storage system
              b.   use equipment that has been installed, calibrated and commissioned in
                   accordance with the manufacturer's instructions
              c.   be capable of detecting a leak at a rate of 0.76L per hour or more with at
                   least 95% accuracy and a probability of false detection of 0.05 or less
                   (United States Environmental Protection Agency (USEPA)
              d.   be certified by an independent third party, consistent with the current
                   USEPA protocols and system of verification (USEPA 1990, 40 Code of
                   Federal Regulation Part 280, Subpart D)
        41.   A Certificate of Compliance must be provided by the independent third party that
              the UPSS leak detection system is consistent with the current USEPA protocols
              and system of verification and be provided to Council prior to the commissioning
              the UPSS.
              Leak Detection System for Underground Tanks
        42.   The following leak detection systems must be used for the underground tanks:
              a.   statistical inventory reconciliation (SIR) that includes a software-based
                   system where daily tank dip readings, delivery records and sales records
                   are entered onto a proprietary software package; or
              b.   automatic tank gauging (ATG) that includes an automatic system using an
                   arrangement of sensor probes and other devices that monitor the
                   underground petroleum storage system and provide inventory information
                   and leak testing;
              c.   a tank pit observation well at the lowest point of each tank excavation pit.
        43.   Leak detection systems for the underground pipework must include:
              a.   electronic line leak detection (ELLD) for pressure piping; or
              b.   safe suction for suction piping;
              c.   for remote fill lines, a statistical inventory reconciliation system to monitor
                   leaks in the fill lines.
