region’s resources.
1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by SDC, this report also
assigns them a rating for their environmental and administrative performance during the period under
review.
Environmental performance is concerned with actual or likely
Streams. In the unnamed tributary, no
significant detrimental effects were found. However at the time of both surveys, 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

required to enter three incidents in relation to
irrigation consents over this period, which resulted in two infringement notices being issued. The overall
rate of non-compliance across all exercised consents was 5%, which was similar to that seen during the
2019-2020 period (4%).
During the 2020-2021 year, 84% of exercised irrigation consents in Taranaki achieved a high level of
environmental performance and compliance with their consents, 11% achieved a good level of performance,

Foreword
We are pleased to present the Taranaki Regional Council’s 2020/2021 Annual Plan, which has a firm focus on
stability in uncertain times while taking into account the challenges and opportunities that will continue to arise
from the COVID-19 pandemic.
We’re budgeting for no change in general rates (0% rather than 3.8% as originally proposed). With the disruption
caused by the
level of environmental
performance and compliance for 878 (87%) of a total of 1007 consents monitored through the Taranaki
tailored monitoring programmes, while for another 96 (10%) of the consents a good level of environmental
performance and compliance was achieved. A further 27 (3%) of consents monitored required improvement
in their performance, while the remaining one (<1%) achieved a rating of poor.
In terms of overall environmental and compliance performance by the consent holder over
