surface). Average annual rainfall for the site is 1,043 mm (taken from the nearby Patea monitoring station). Origin Energy Ltd.’s Kauri D wellsite is situated in the eastern corner of the site, and there is a small coastal lake inland and to the northeast (up gradient) of the storage pit area. Both of these operational features are presented in Figure 1. Figure 1 WRS Waikaikai Landfarm and regional insert page 5 A summary of the site data is provided below:
reported to be compliant with consent conditions at the time of inspection. 9 December 2019 It was found that all materials at the site were permitted by the conditions of the consent. It mostly consisted of broken concrete. There had been recent heavy rainfall resulting in only a few small puddles, with no run off observed. There were no matters of concern to note during the inspection. In the composting area it was found that the site remained well bunded with only some puddles present …
environmental effects if it was buried with the green waste rather than being removed. During the year under review no unacceptable material was dumped at the Patea Beach green waste discharge site. There has been no leachate observed discharging from the sand dune area or the stockpiled green waste during the period under review, or in previous years. These factors, combined with the sandy substrate and low rainfall at the beach would be restricting the production of leachate from the green waste.

inspection. 30 June 2022 During this inspection, no runoff was observed offsite or past bunded areas. There was some ponding of water beneath pig pens, with recent heavy rainfall likely a contributing factor. The methane generator was not running at time of inspection and the methane pit was half full with some water present atop cover. Odour was localised to immediate vicinity of piggery. The effluent ponds were full but not discharging to the stream. Compliance at time of inspection.
48 mm of rainfall recorded at the Hillsborough monitoring station in the seven days prior to the inspection. There were no off-site odours or dust issues observed prior to going on site. Very little refuse was noted on Colson Road between the transfer station and the landfill gates. The culvert grate at the inlet to the SPCA driveway culvert was clear with a moderate, slightly cloudy, flow in the main branch of the stream. No scums, sheens or debris were present. The side tributary that …
