Licence Condition numberType of non-complianceEPA actionsNo. of times occurred
1.4 Thirteen overflows of the reticulation system reached waterways in dry weather, due to blockages caused by tree roots, debris, fat buildup or broken structures. N/A N/A
3.2 95KL of effluent was released without full treatment due to the failure of the Uninterruptable Power Supply (UPS) on 9.8.02. N/A N/A
3.2 Biological by-pass allowed 95KL of partially disinfected effluent to be released on 4.11.02. N/A N/A
3.2 Biological by-pass allowed 9.95 ML to be released on 28.4.03. The effluent was fully disinfected but only partially treated. N/A N/A
3.2 & 3.4 Biological by-pass occured during extreme wet weather on 13.5.03. Not all flows were fully treated or disinfected. N/A N/A
3.2 Biological by-pass occured on 12.6.03 due to power failure occurred to the Prog Logic Controller (PLC). Effluent was partially treated but fully disinfected. N/A N/A
3.1 Effluent exceeded 3DGM of TSS limit on 15, 16 & 17 May 03 - 31.6 mg/L; the licence limit is 30 mg/L. Poor hydraulic configuration and scum accumulation at the secondary process may be the problem. N/A N/A
2.1 Sample collected at pt 3 instead of pt 17. Both pts are on the same line and next to each other. This occurred on 7 occassions. N/A N/A
2.1 Autosampler did not operate properly on 24.8.02 at pts 3 and 17. N/A N/A
5.1 Ongoing improvement and no deterioration from existing system performance could not be demonstrated, because of insufficient information on existing system performance in 1994 benchmark year. N/A N/A
5.2(c) Comparison of wet weather overflow performance in reporting year with 1994 benchmark year performance not done, because 1994 benchmark year hydraulic sewer system model could not be developed / calibrated to accuracy required by the licence. N/A N/A
6.1 Comparison of wet weather STP overflow performance in reporting year with 1994 benchmark year performance not done, because 1994 benchmark year hydraulic sewer system model could not be developed / calibrated to accuracy required by the licence. N/A N/A
6.2 Comparison of wet weather STP overflow performance in reporting year with 1994 benchmark year performance not done, because 1994 benchmark year hydraulic sewer system model could not be developed / calibrated to accuracy required by the licence. N/A N/A
