Whilst the average daily discharge limit was exceeded on two consecutive days under high rainfall conditions, the Company identified and eliminated stormwater discharges to the system in a timely fashion. Additional operational changes were made to minimise daily discharge volumes. The wastewater treatment system at the Retreat did not adversely affect the water quality of the local freshwater and coastal environments. The results of this sampling suggested that the Retreat was not influencing
to COVID lockdowns and extra COVID measures in August and September 2021, followed by an extended dry period over summer and autumn in Taranaki. A four-yearly shutdown was being undertaken at the site during suitable rainfall in May and June 2022, and with the number of contractors onsite and extra COVID measures in place, it was mutually agreed that only offsite samples would be collected by Council. OMV samples the combined stormwater and oxidation ponds discharge downstream of the final
substrate and low rainfall at the beach would be restricting the production of leachate from the green waste. It is therefore considered that, so long as STDC continues to monitor for and remove exposed unacceptable material from the coastline, the environmental effects from the activities at the site are likely to be no more than minor. 3.3 Evaluation of performance A tabular summary of the consent holder’s compliance record for the year under review is set out in Table 2.

the tributary (WIT000460) exceeded the historical maximum count for that site. High counts such as these are typically associated with heavy rainfall and the resultant increase in agricultural runoff. However, the lack of precipitation prior to sampling page 14 indicates that rainfall was not a significant factor in these results. As the counts were high at sampling sites upstream of the septic tank and sewage pump station it is unlikely that these results would be due
effects. Ring drains and bunds were clear and fit for purpose. Everything was satisfactory. 23 May 2013 Inspection was undertaken following significant rainfall in previous days. The skimmer pit contained discoloured water as a result of run-off from construction activities at the site. There were no visual effects from this discharge on the receiving waters. The ring drain near the generation unit had a section of damaged plastic liner. The newly constructed ring drain on the eastern boundary
includes effluent storage that is sized with account for historic local rainfall data, but does not specifically take into account climate change effects on rainfall. Climate change predictions for Taranaki generally anticipate more drought and a greater frequency and intensity of storm events. I will use best practice dairy effluent management, to maintain suitable effluent storage capacity that will enable deferred effluent discharge to land until suitable weather and soil conditions. My
rainfall events, or if animals have direct access to waterways. Human faecal contamination of waterways can occur via poorly treated sewage or septic tank systems, or during heavy rain when sewerage systems cannot cope and they overflow into stormwater systems. Because of these heightened health risks from runoff and stormwater, people are often advised to avoid swimming for 48 hours after prolonged or heavy rain. There are two distinct components to assessing the suitability of a site for
