It holds 132 resource consents for sewerage, water, stormwater, harbour use, road reserves and parks. Water and refuse top the list at 35 each, followed by road reserves at 29 and water sewerage at 31.
Those consents have a total of 1175 conditions and 964 ''demonstrations'', which include regular monitoring, testing and reporting to the authorities who issued the consents.
In the 24 months from June 2010 to June last year, the council had 39 breaches or 4% non-compliance, water and waste water manager Martin Pacey said in a report to a council committee.
None was sufficient for an abatement notice to be issued, one of the council's aims.
Mr Pacey said many of the breaches were minor and one-off.
This is the first time the council has provided to councillors and made public full details of its consents and breaches.
Staff had been working on strategies to resolve non-compliances with the ultimate target of having none.
''However, this goal is still some time away,'' he said.
Of the breaches listed by Mr Pacey, one of the biggest problems is with the Moeraki sewerage scheme, which consistently failed to meet some of the conditions in terms of standard of treatment and discharges during all or most of the two years covered by the report.
It has consistently breached standards for nitrogen and phosphorus in discharges and, for half the time, the E. coli count in discharges.
The council is working with the Otago Regional Council on upgrading the plant to meet conditions, which have been very stringent compared with some of its other sewage treatment schemes.
The Oamaru sewerage scheme has performed well, although in the 12 months from July 2011, consistently failed to meet standards on its inlet.
Other sewage treatment schemes at Otematata, Omarama and Palmerston have generally met consent conditions, except for occasional breaches, during the 24 months.
The same applies to water schemes.
However, the Palmerston refuse disposal site continues to prove difficult, regularly exceeding the boron limit in leachate discharges.
