southern coastline, where dunefields extend inland for several kilometres. Less than
2% of the Taranaki region is classified as coastal sand country.
The Taranaki coastline is exposed to the west, and as a consequence, high energy
wave and wind conditions dominate the coastal environment. Almost the entire
Taranaki coastline is subject to varying rates of erosion from waves and wind. This
has resulted in a predominantly cliffed coastline, with the western coast
characterised by
closer to achieving
sustainable development of the region’s resources.

1.1.4 Evaluation of environmental performance
Besides discussing the various details of the performance and extent of compliance
by the consent holder/s during the period under review, this report also assigns a
rating as to each Company’s environmental and administrative performance.
Environmental performance is concerned with actual or likely effects on the
receiving
significance of the trend was determined using the p value (p < 0.05 = significant).
When multiple correlations are undertaken, there is a chance that some will be found to be significant
purely by chance. In order to deal with this potential problem, the Benjamini-Hochberg False Discovery Rate
(FDR) method was applied to the results of the Mann-Kendall test. Further justification for this statistical
approach can be found in Stark and Fowles (2006).

detrimental effects were found at the time of the November survey. At the time of the March
survey the results suggested poor preceding water quality that may be indicative of adverse effects
associated with the landfill leachate.
Air quality monitoring showed that there were no significant adverse effects in relation to suspended
particulates, dust deposition rates or odour beyond the site boundary.
An enclosed gas flare system was installed for air quality control during the 2017-2018
the TRC to take up to 60,480
m3 per day at a maximum rate of 740 l/s of water from Lake Mangamahoe in the
Waiwhakaiho Catchment for municipal water supply purposes.
