supply depends on minimum flow and allocation. Restrictions can be either total
(i.e. no taking permitted) or partial, whereby some reduction in take rates is required to maintain
compliance with minimum flows. The number of days with total restriction depends on the
minimum flow, as no abstraction is allowed once the river flow falls below the minimum flow (Fig.
21). Allocation affects the number of days there is likely to be partial restrictions with a 10% increase
in allocation causing about
them a rating for their environmental and administrative
performance during the period under review.
Environmental performance is concerned with actual or likely effects on the receiving
environment from the activities during the monitoring year. Administrative
performance is concerned with STDC’s approach to demonstrating consent compliance
in site operations and management including the timely provision of information to
Council (such as contingency plans and water take data) in
Offshore Petroleum Drilling Review (2015).
Accelerated erosion: movement of regolith and/or soil at rates more rapid than natural erosion
rates, and due to human influence. The most important human activity promoting accelerated
erosion in the eastern hill and sand country of Taranaki is vegetation clearance. Accelerated erosion
is comprehensively reviewed for Taranaki by Hicks (1998).
Area of interest (coastal sand country sites): the area of sand dunes and sand flats within the
chosen sand country monitoring sites, and as defined by
skimmer pits and the final discharge point from the skimmer pits on to land and then
any potential receiving waters.
During each inspection the following are checked:
• Weather;
• Flow rate of surface waters in the general vicinity;
• Flow rate of water take;
• Whether pumping of water was occurring;
• General tidiness of site;
• Site layout;
• Ring drains;
• Hazardous substance bunds;
• Treatment by skimmer pits/sedimentation pits;
• Drilling mud;
• Drill cuttings;
• Mud pit
the performance and extent of compliance
by the consent holder during the period under review, this report also assigns a
rating as to NPDC’s environmental and administrative performance.
Environmental performance is concerned with actual or likely effects on the
receiving environment from the activities during the monitoring year.
Administrative performance is concerned with the consent holder’s approach to
demonstrating consent compliance in site operations and management including the
and dust deposition rates were
within guideline levels.
During the monitoring period there was one occasion where ammoniacal nitrogen levels in
the Puremu Stream exceeded consent limits, but after investigation it was found to be most
likely due to low flows and rural inputs rather the landfill itself. Ammoniacal levels in the
Puremu Stream returned to normal background levels after flows returned to normal. The
Manganaha Stream continued to show no effects from the landfill.
There
management and, ultimately, through the refinement of methods and
considered responsible resource utilisation, to move closer to achieving sustainable
development of the region’s resources.
1.1.4 Evaluation of environmental and consent 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.
It is recommended that future biological monitoring is carried out in conjunction
with physicochemical water quality monitoring, in order to assist with determination of the causes of the
poor results.
Air quality monitoring showed that off site 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 during the monitoring period and there was only one
re-deployment of the equipment
anywhere in New Zealand by advising and/or procuring transport arrangements at the
MNZ’s expense.
Except when deployed for actual or simulated oil spills, store the equipment at all times
in a secure, clean and dry storage area enclosed from the weather and free of vermin.
Recover from the polluter the cost for the equipment’s use in a marine clean-up response.
The rates to be charged of the polluter are those established by the MNZ for the hire of
the
