Consents & Regulatory minutes June 2021

in this high rainfall area is being investigated. The requirement to discharge to land, in most cases, addresses cultural and water quality concerns. Recommended That the Taranaki Regional Council: a) receives this memorandum b) agrees that from December 2022 consent holders applying for a consent renewal will be required to immediately start discharging to land once their consent has been issued c) agrees that those consent holders whose consents are about to expire be

Wai iti Beach Retreat Annual Report 2023-2024

6). Contrary to historical data, the upstream site had higher E. coli numbers, with counts 10m downstream of the unnamed tributary lower than both upstream and the stream at the beach sites. As the Wai-iti Stream is surrounded by farmland, it is therefore unlikely that high FIB counts were only attributed to the WWTP in operation. Additionally, the area experienced moderate to heavy rainfall from early to mid-morning three days prior to sampling. The accumulation of agricultural, stormwater

incorporating odour surveys and four surface water samples collected for physicochemical analysis. The water samples from the unnamed tributary of the Waiongana Stream indicated that the Company were in compliance with consent defined conditions on the four occasions they were collected. It is noted that the stormwater facility discharge to surface water, only occurs during significant rainfall events. The Company continues to be proactive in their response to objectionable odour

Appendix Z - Uruti composting facility nitrogen balance

nitrogen concentration in the pond and the rainfall 30 days prior to the sampling event. This was based on 7 ammoniacal nitrogen concentrations measured between October 2017 and April 2019. The relationship has an R2 value of 74%. Using this relationship, the monthly rainfall from 2018 was used to calculate monthly nitrogen concentrations in the pond. The concentration was converted to a loading rate in kg/ha/month based on the volume irrigated (calculated from 2018 irrigation hours and an

The Taranaki Region

climate, with abundant rainfall and high sunshine hours, makes the region lush, green and fertile. Rainfall Annual rainfall varies throughout the region. Some coastal areas receive less than 1,400 mm annually, while the summit of Mount Taranaki receives around 7,500 mm. Heavy rainfall events do occur and there can be extremes. In 2012 heavy rain caused a number of slips on the coastal road around Mount Taranaki, including a large slip at Oākura that covered the road, burying a

“Therefore the calculations provided by RNZ are extremely conservative, if not a completely unrealistic assessment of page 10 the effects of nitrogen”. In the defence of using the 225 g/m3 concentration I make the following points: A) The amount a nitrogen applied to the irrigation fields is a combination of the nitrogen concentration in the irrigation pond and the volume of fluid irrigated. In summer there is less rainfall and the evaporation from the pond

Policy and Planning Committee Minutes July 2022

Report 2017-2020. 5.2 It was noted that Council would like to increase the number of monitoring bores, especially within the eastern parts of Taranaki, to improve understanding of areas where there is limited data and information. 5.3 Water allocation in the region is well within current allocation limits and monitoring shows that groundwater levels are generally stable, with fluctuations the result of seasonal rainfall and pumping effects. It was noted that we are already starting to see

Taranaki Irrigation Study

simulation model, developed by CSIRO, Australia. The value of pasture ($/kg-DM) was estimated using local farm parameters that were developed in consultation with Louise Hofmann, Taranaki FarmWise consultant. The results of that work showed that the values of pasture in the area range between $0.17 to $0.25/kg-DM, with an average value of $0.22/kg-DM. Based on these values the irrigation marginal benefits were calculated for a range of rainfall and soil combinations for three values of pasture:

monitoring year, with most commencing irrigation in November or December and concluding in February. Rainfall recorded at the Council’s monitoring locations over the summer irrigation period ranged between 55 % and 111% of historical mean values. A particularly dry November and December lead to a drought being declared in Taranaki during 23 December 2017. As a result, irrigation water demand was high during the 2017-2018 irrigation season, with a total water use across all exercised irrigation
