1. The Castle Hill Wind Farm Project
Genesis Energy is proposing to construct and operate a wind farm in northern Wairarapa,
known as the Castle Hill Wind Farm (hereafter referred to as “CHWF”). The CHWF Site is
located 20km east of Eketahuna and Pahiatua, 20km north-east of Masterton and 15km west of
the Wairarapa coast north of Castlepoint (Figure 1, Appendix A). The CHWF Site covers an
area of approximately 30,000ha.
The CHWF Site is characterised by undulating hills of predominantly pastoral grass, with grazing
by sheep and cattle. Stands of native vegetation are located throughout the Site, particularly in
gullies, with several small forestry blocks scattered across the Site. The topography is varied,
with elevation ranging from 200m to 500m above sea level.
The CHWF Site is located in a remote area that is sparsely populated. There are six small ruralsettlements in or around the CHWF area including Tinui, Pongaroa, Alfredton, Makuri, Tiraumea
and Bideford. These six settlements had a combined population in 2006 of around 500 people
in 110 households1. Masterton (population 18,000), Pahiatua (population 2,600) and Eketahuna
(population 460) are the larger townships located within 30kms of the CHWF Site2 (Figure 1,
Appendix A).
Key components and features of the CHWF project include:
• Turbines: plant consisting of foundations, tower, nacelle and rotor for conversion of
wind energy into electricity.
• A Turbine Corridor: 3,144ha identified as suitable for turbine placement. Turbines
will be located within this corridor.
• Turbine Clusters: groupings of turbines for ease of reference.
• Turbine Configurations: up to 286 Medium Turbines (maximum tip height 135m) or
up to 242 Large Turbines (maximum tip height greater than 135m but no greater
than 155m) or a mixture of Medium and Large Turbines installed within the Turbine
Corridor.
• Internal Roads: roads constructed within the CHWF Site for transporting wind farm
components, materials and personnel within the Site and to allow access aroundthe Site for construction and operational activities.
Draft Environmental Management PlanCastle Hill Wind Farm

• Electrical Balance of Plant (EBoP): All electrical structures and equipment related to
the collection and reticulation of electrical power around CHWF to the point of
connection to the External Transmission Line. Plant includes an Internal
Transmission Line, 33kV overhead lines, 33kV underground cables, a MainSubstation and Satellite Substation, an optional Switching Station and switch gear
huts along with other associated electrical equipment.
• Monitoring masts: up to 16 monitoring masts to collect on-going meteorological
information during the operational life of the CHWF.
• External Roads: Public roads near the Site that are planned to be used for traffic
associated with the construction and operation of the CHWF and by Over-weight
and Over-dimension Vehicles (OW/OD Vehicles).
• Earthworks associated with the construction and maintenance of the CHWF.
• Temporary construction infrastructure: components required for construction of theCHWF including Concrete Batching Plants, Central Laydown Areas, Excess Fill
Areas, Contractor Compound, quarrying and crushing facilities and water storage
and abstraction facilities.
• Operations infrastructure e.g. operations and maintenance buildings (O&M
facilities).
The Turbine Corridor, Turbine Clusters, Internal Roads, Substations and the Internal
Transmission Line are shown in Figure 2, Appendix A. External Roads are shown in Figure 3
(Appendix A), and wind farm components are shown on Figures 4, 5, 6, 7 in Appendix A.
The generation capacity of the CHWF is in the order of 600MW. The maximum capacity will be
dependent on the type of turbine eventually selected for the Site but current Site and wind
turbine analysis indicates a potential capacity of up to 860MW.
Development of the CHWF may progress in stages, with any first stage being in the order of
300MW. This capacity depends on the wind turbine model selected, but will also depend on

6. Revisions and EMP Evolution
This section of the EMP establishes the process and approach for documenting changes madeunder the adaptive management approach and also the protocol for managing design
finalisation. The adaptive management approach involves regular monitoring and reporting which
creates a continuous improvement feedback loop and ensures that actual On-site effects are
being addressed and managed appropriately.
Genesis Energy will operate a “plan-do-check-act” adaptive management approach. The
approach enables objectives to be set, actions to be monitored and performance to be
evaluated against those objectives and for this to be communicated to relevant stakeholders. It
will enable reviews of progress to check the effectiveness of actions and to ensure that
improvements are implemented accordingly.
6.1 EMP Evolution and Control
The EMP is subject to revision based on review, experience and changes in technology, thereby
taking an adaptive approach to improve future management. The key mechanisms for this
include the following:
• Review of measures utilised to manage effects.
• Improvements identified from any incident response.
• Consultation with relevant stakeholders.
• Undertaking an annual review.
To maintain control over any changes in approach made through the evolution of the EMP, this
EMP has been issued as a controlled document. Any other copies issued in part or full are
deemed not to be controlled copies and will not be updated nor may they be considered a
current document. All copies shall be distributed in accordance to the document register. On
receipt of a revision the copyholder shall discard the superseded copy and adopt the new copy.
6.2 Component Location Consenting Approach
Overall, the environmental effects assessment for the CHWF Project has been undertaken on a
comprehensive, conservative and robust basis.
The AEE, and the supporting technical information, [is/was] provided in such detail as
corresponds with the scale and significance of the effects that the CHWF activities may have on
the environment. As noted, the CHWF Site encompasses some 30,000 ha, with a construction
footprint of 861 ha and an operational footprint of some 226 ha. In order to provide an
assessment of all potential environmental effects (positive and negative), independent experts
Draft Environmental Management PlanCastle Hill Wind Farm
13
[have undertaken/undertook] both specific and representative effects assessments. Thus, while
not every spatial area of the 30,000 ha Site [has been/was] specifically assessed, the worst
case position for all potential effects [has been/was] assessed regardless of the final location of
all the activities for which resource consent has been [sought/granted].
Optimisation of the CHWF design [is/was] proposed to make the best use of the wind resource
while responding to technological advances, opportunities to minimise environmental effects
and in order to take account of Site conditions following grant of resource consent. When
implementing the CHWF project, Genesis Energy will ensure that final designs fit within the
overall location and extent of effects described in the AEE and authorised by the resource
consents [sought/granted] . It will ensure that the nature and scale of the effects associated with
the final design are no greater than the authorised adverse effects.
In that regard, it is anticipated that the following protocol will form part of the conditions of
consent.
6.2.1 Protocol for Managing Design Finalisation
During the development of the final design, the following protocol will apply:
1. Confirm the final location of the CHWF components.
2. Document the reasons why the final location has been selected.
3. Prepare detailed design drawings.
4. Ensure that exclusion areas where infrastructure shall not be located contain noinfrastructure elements apart from those specific locations sought in the AEE.
5. Undertake a confirmatory process to ensure environmental effects are no greater thanthat contained in the AEE.
6. Report the findings of the confirmatory process, to confirm that for the project as awhole:
a. Areas of legally protected habitats (DOC, QEII) and, ‘rare’, ‘threatened’ or‘at risk’ habitats identified under statutory plans will not be disturbed.
b. Areas of ‘high ecological value’ as defined in the Ecological Effects Assessment in support of the AEE will be avoided, except to the extentalready outlined in the CHWF Project Figures shown in the AEE. Clearanceof a limited amount of ‘high ecological value’ vegetation is described andthis quantity will not be exceeded in construction of the CHWF.
c. Clearance of indigenous vegetation will be minimised and will not cause themaximum quantity of indigenous vegetation clearance of 66 ha described inthe AEE to be exceeded.
d. Watercourse crossings will not vary in location by more than 100m each
Siting refinement is important to allow for variation in spacing between Turbines to
maximise energy output. Spacing variesdepending on the size of the Turbine rotor andtherefore, optimal spacing can only bedetermined once the final turbine model(s) areselected after resource consent acquisition.Four Indicative Turbine Layouts have beenestablished to provide a basis for representativeengineering and environmental assessments andto illustrate how different Turbine sizes may beplaced within the Turbine Corridor.
Turbines may not be sited anywhereother than in the Turbine Corridor.
TurbineCorridor
The Turbine Corridor incorporates all areaswithin the CHWF Site identified for turbine
placement. The development and refinement ofthe Turbine Corridor has incorporatedrepresentative environmental and engineeringassessments to avoid, remedy or mitigateadverse environmental effects.
The area and location of the TurbineCorridor is located where indicated
in the CHWF Project Maps.
InternalRoads
(includingLay-bys)
Internal Roads have been designed andassociated earthworks volumes calculated andwill generally be located where indicated.However the scope sought within the resourceconsent will enable the final location of theInternal Roads to be confirmed during thedetailed design phase. Further refinement may
be required due to the following:

33kVoverheadlines andundergroundcables
Wherever practical, the 33kV reticulationsystem will follow Internal Roads so therequirement for variation from the routesindicated will match that of the Internal Roads.
The opportunity arising from refinement, and thedegree of constraint applied is as for the InternalRoads.

8. Construction Environmental Management
This section of the EMP outlines the proposed general environmental management measures to
be implemented to address environmental effects. Detailed methods for specific sites and
issues will be identified within the SEMPs, provided in appendix to the EMP.
8.1 General Operations
Works will not commence On-site until the following actions have been undertaken:
• Pre construction conditions of resource consent have been met and authorised by
Council.
• All other approvals required from Council have been received for a given project
area.
• Relevant EMPs and SEMPs are have been approved by the relevant authority.
8.2 Provision of Information, Training and Inductions
All organisations and individuals working on the CHWF project will be required to complete a
formal Site induction prior to commencing work On-site. The induction will include importantenvironmental issues pertaining to the Site including environmental management requirements,
accidental discovery of cultural or archaeological sites or material, emergency response
procedures and incident reporting, as well as Health and Safety information and requirements.
Attendees will be provided with a copy of the EMP and any appropriate SEMP to read prior to
commencing work On-site. A register will be maintained by the contractor’s Project Manager
which needs to be signed prior to an individual commencing work On-site confirming they have
understood the contents of the EMP and relevant SEMPs.
Should any specialised environmental training be identified as being necessary for personnel at
the Site, training will be provided by a suitably qualified person. A record of the training will bekept by the contractor’s Project Manager.
Environmental issues and management will be included as an item on the agenda of daily
toolbox meetings to assist in the continuing development and improved performance of
Draft Environmental Management PlanCastle Hill Wind Farm

9. Erosion and Sediment Control Measures
Exposure of soil during the construction process and the formation of topsoil and weatheredrock stockpiles, means that there is potential for an increase in erosion and sediment
discharges, including airborne dust. Accordingly, erosion and sediment control measures
will form integral components of the construction process for the CHWF, with appropriate
planning and adoption of control measures for all earthworks to minimise the effect on the
receiving environment.
The minimisation of erosion is the most effective way of reducing sediment discharges.
Earthworks activities associated with the construction process will be kept to the minimum
area necessary, and exposed surfaces will be stabilised until the Site is appropriately
revegetated.
The following general objectives underpin erosion control at the CHWF:
• Minimising the area disturbed by construction activities.
• Progressively completing construction activities on a stage-by-stage basis.
• Revegetating and rehabilitating areas disturbed as soon as possible after
earthworks have been completed.
• Stabilising material storage areas for future use.
In addition, the potential effects associated with earthworks activities can be prevented and
minimised with the following guiding principles:
• Maintain separation of earthworks from watercourses.
• Divert clean surface runoff away from areas of earthworks or soil stockpiles.
• Reduce the energy of surface flows in areas of potential erosion.
• Allow for the passage of extreme flows and protect against blockage of
infrastructure.
• Provide containment for sediment entrained in surface flows.
• Treat sediment laden water leaving the construction site.
• Promptly stabilise or revegetate disturbed areas.
• Monitoring to ensure erosion and sediment controls are operating effectively.
A range of erosion and sediment control measures will be implemented as part of the
construction process associated with CHWF. These measures will be contained within
relevant ESCPs and are summarised below. The ESCPs will set out measures to avoid and
minimise potential impacts of construction works on soils and waterways at the Site, and
will be prepared for each phase of development and submitted to Council prior to
Draft Environmental Management PlanCastle Hill Wind Farm

9.1.7 Drop Pipes
Drop pipes are temporary structures used to convey runoff from a channel or other type of
collection point down a steep slope without requiring an overland flow. The entrance to thepipe is flared and constructed of compacted earth reinforced with geotextile.
9.1.8 Flow Dispersal Outlets
Flow dispersal outlets are connected to a section of drainage coil or pipe that has had slots
cut into it fixed perpendicular to the slope in order to promote broad sheet flow rather than
a concentrated flow. This is suitable where flow is being discharged away from a
watercourse. The dispersal device must be laid flat and perpendicular to slope so that flow
will exit from the full length of pipe rather than concentrated at one point.
9.1.9 Rip-rap reinforced Outlets
A basin, wingwall, or other suitable structure based on existing relief to prevent scour and
erosion at and around outlets. This is suitable where flow is being discharged to a
watercourse. Depending on the situation, armouring of the opposite side and/or
downstream channel of the stream bank may also be required.
9.1.10 Stream Flow Diversion
A stream flow diversion diverts perennial water flows around a works area that is located in
a watercourse.
9.2 Sediment Control
In combination with the erosion control measures set out above, a suite of sediment control
measures are proposed for the CHWF Site. A summary of sediment control measures are
set out below.
9.2.1 Silt Fences
Silt fences are a barrier device comprising a geotextile fence used to intercept sediment
laden runoff from areas that are either unable to drain to, or are of a size that does not
warrant a communal sediment control device. Silt fences will be installed on a contour and
service catchment area’s below 0.5 ha as required.
9.2.2 Super Silt Fences
Super silt fences are the same as for silt fences but include chain link and tensioned wire for
reinforcement of the geotextile. The fence is reinforced with chain link at 400mm and
800mm above ground, comprising a double layer of geotextile from 400mm above ground
Draft Environmental Management PlanCastle Hill Wind Farm
34
to 200mm below ground. Super silt fences will be used to service catchments larger than
0.5ha where no other sediment control method is suitable.
9.2.3 Sediment Control Ponds
Sediment control ponds are a temporary pond with storage volume and outlet structure
designed to provide sufficient settling time for sediment to settle out for a range of events
up to the design storm. Ponds require maintenance by way of excavation when 20% of
total volume is lost to accumulated sediments. A level spreader will be used between the
forebay and the pond to ensure infows do not cause sediment re-suspension. Pond
catchments should generally be limited to less than 3 ha in area.
9.2.4 Sediment Control Ponds with Flocculation
Same as for sediment control ponds, but include a flocculation dosing system to aid the
settlement of suspended solids. Bench scale tests will be undertaken to determine the
suitability of flocculation systems, and if suitable, appropriate dosing rates. Dosing systems
include batch dosing, rainfall activated liquid dosing, and flow activated dosing.
Flocculants can be toxic to fauna, so stringent care will be taken to establish and operate
correct dosing regimes that ensure residual levels are safe in the environment. Flocculation
pond catchments should generally be limited to an area less than 5 ha.
9.2.5 Decanting Earth Bunds
A Decanting Earth Bund is a compacted earth bund established to created an impoundmentarea where runoff can pond and allow sediment to settle out. This is similar to a sediment
control pond but with a different outlet type and without a forebay. Catchments should
generally be limited to less than 0.3 ha and bunds will be excavated when 20% of total
volume lost to accumulated sediments.
9.2.6 Improved Decanting Earth Bund
Same as Decanting Earth Bund but with improved inlet and outlet systems as used by
sediment control ponds. A level spreader will be used at the inlet to the bund to ensure
inflows do not cause sediment re-suspension. Improved bund catchments will be limited toless than 1.5 ha and bunds should be excavated when 20% of total volume lost to
accumulated sediments.
9.2.7 Wheel Wash Stations
A wheel wash station is a flooded basin lined with agitators to remove sediments
accumulated on the wheels of trucks prior to them exiting the Site. Daily flushing of basins
will occur, with effluent being discharged into a sediment control device and any
contaminants treated in an appropriate manner. Generally wheel wash stations will be at the
Site exits onto a sealed road, and often used in conjunction with a stabilised entrance.

9.3 Stabilisation or Surface Treatment Methods
Stabilisation and surface treatment methods will utilised at the CHWF. The use of these
measures will be refined based on site specific requirements and On-site experience. A list
of those methods that will be considered for use in the appropriate circumstances at the
CHWF is set out below.
9.3.1 Surface Roughening
Surface Roughening consists of track rolling to roughen a bare surface to slow the velocity
of sheet flow, prevent runoff concentrating into erosive rills, and aid the establishment of
vegetative cover.
9.3.2 Stabilised Construction Entrance
A stabilised construction entrance is a stabilised pad of aggregate or asphalted to prevent
erosion at a highly trafficked area, and to provide an opportunity for dust accumulated on
the truck scrape to be vibrated off. The drainage from stabilised entrances will discharge to
a sediment control device and contaminants treated in an appropriate manner.
9.3.3 Staging Works and Progressive Stabilisation
Staging or sequencing of construction and progressive stabilization and rehabilitation is a
function of construction planning. Staging requires work areas to be segmented intoseparate task areas that can be opened and then completed prior to moving onto
successive areas. These completed areas will be stabilised as they were finished, resulting
in the Site being progressively opened and then stabilised. This ensures that the minimum
area of soils are exposed at any one time and also allows for high risk work to be planned
over summer while lower risk work can be scheduled for winter works.
9.3.4 Top Soiling and Grass Sowing
Spreading topsoil and sowing grass seed to permanently stabilise exposed areas will
receive a minimum thickness of 100 mm topsoil (depending on available supply at the Site).
9.3.5 Mulching
Mulching involves spreading straw or other suitable materials to protect exposed surfaces
from erosion and to promote establishment of vegetative cover. A sufficient quantity of
mulch needs to be applied to form a protective layer over the exposed surface. Mulching
will be used as temporary measure at the Site or will be used in conjunction with top soiling
Draft Environmental Management PlanCastle Hill Wind Farm
36
9.3.6 Geotextile
Geotextiles (woven or other artificial but non-degradable geotextile) will be used for the
protection of exposed areas. The type, thickness, strength and hydraulic performance of thegeotextile used depend on the situation and purpose of use. Common uses include lining
steep channels, providing removable stabilisation overnight or during inclement weather,
and lining excavations prior to placement of riprap or aggregate.
9.3.7 Biodegradable Fibre Matting
Biodegradable Fibre Matting is used to protect exposed areas and to promote
establishment of vegetative cover, often to stabilise topsoil and grass sown on steeper
slopes.
9.3.8 Hydroseeding
Hydroseeding activities will apply a mixture of grass seed, fertiliser and a binding agent
(usually wood or paper pulp) sprayed onto steep or otherwise critical exposed areas.
9.3.9 Tackifier enhanced Mulching or Hydroseeding
Tackifiers are polymers which are added to hydroseeding pulp to improve immediate
erosion protection and to aid adhesion to exposed surfaces. These tackifiers are often also
used as flocculants in sediment control ponds. Any restriction on the use of tackifiers will be
considered before application.
9.3.10 Spray Concrete
Spray concrete is a high cement content grout which is applied to immediately stabilise and
reinforce steep slopes and other critical areas. This will be used to stabilise loose rock on
steep batters adjacent to roads and bridge abutments.
9.4 Maintenance of Erosion and Sediment Control Measures
Ongoing maintenance of erosion and sediment control structures is necessary to ensure
that they remain fit for purpose and functional in a wet weather event. Such devices will be
inspected as part of the supervision duties undertaken by responsible parties and
maintained in working order whilst they are required. Inspections shall occur prior to, during
and after prolonged periods of heavy rain, as appropriate. Any defects will be promptly
rectified.
Intensive monitoring and maintenance will be required to optimise and maintain erosion and
sediment controls during construction. This will include:
• Maintaining access to ponds and decanting earth bunds following wet weather;
Draft Environmental Management PlanCastle Hill Wind Farm
37
• Cleaning out ponds and decanting earth bunds following heavy rainfall and high
sediment load events;
• Signposting ponds and decanting earth bunds to identify them;
• Maintaining open communications and cooperation with Council appointed
compliance staff;
• Maintaining electronic records of device condition (including photos and
inspection records);
• Providing as built drawings of key ponds and decanting earth bunds and their
catchment areas; and
• Monitoring occurrences of and managing stock interference with erosion and
sediment control measures.
In addition to specific measures, topsoil that is to be used in revegetation will be stockpiled
away from drainage lines and watercourses. These areas will be managed to minimise
erosion with surface stabilisation to prevent wind erosion.
9.5 Removal of Erosion and Sediment Control Measures
Erosion and sediment control measures will be monitored and maintained as set out in the
EMP and ESCP(s). When the use of control measures is determined to no longer be
necessary (construction activities are completed and reinstatement and revegetation of thedisturbed area implemented), Council will be advised that the area has been adequately
stabilised and that risks from erosion are low.
For clarity, removal shall only be considered when the area in question is inherently resistant
to erosion or rendered resistant. In terms of revegetation by way of grassing or
hydroseeding, inherent resistance is determined to be when ground cover is in excess of
Draft Environmental Management PlanCastle Hill Wind Farm
38
10. Water Management
General drainage works may be required across the Site to manage any seepages duringthe earthworks activities. Surface discharges from seepages and any springs that are
covered by construction earthworks (e.g. Excess Fill Areas) will be diverted beneath the fill
to discharge at a suitable downslope location. This will be achieved by installing under-
drainage beneath the fill areas where appropriate
Open excavations (for example Turbine Foundations) may collect either ground or rain
water. If this occurs, the excavation will be dewatered, most likely by pumping. Discharges
generated by this will be treated in accordance with the ESCP(s) and Drainage Management
Plan (DMP).
Some Internal Roads, Central Laydown Areas, turbines, Excess Fill Sites or other site
elements have been sited over an existing On-site pond. Where this occurs the ponds are
usually relatively small locally constructed retention areas used by farmers and do not hold
large volumes of water, or similarly small natural depressions where water has been allowed
to accumulate. If required, ponds will be de-watered in a controlled manner and if
appropriate, treated in accordance with the ESCP and DMP. It is not expected that this
practice will be necessary at many sites.
In addition to the ESCP (Appendix F), a draft example of the DMP is also provided in
Appendix K. This sets out the purpose, objectives and content for the DMP.
10.1 Quarry Water Management
It is estimated that 0.24 m3 of water will be required for each 1m3 of gravel in the crushing
process. Once the gravel aggregate has been sorted it will be transported to the Concrete
Batching Plant for concrete production or it will be stockpiled for use in road formation.
Detailed water management measures for quarries and aggregate processing will be
established and set out in detail in Quarry Management Plan (QMP) located in Appendix H.
Typical arrangements will include:
• Quarries will be surrounded by a cut-off nib or bund, and will drain to a multi
stage settling pond.
• Recycled water will be drawn off from this.
• Excess clean water will discharge in a controlled manner onto grass slopes.
• Sludge in settlement ponds is likely to contain a very low level of contaminants.
This will be tested during construction in accordance with the agreed monitoring
approach. Un-contaminated sludge (essentially silt and clay) will be included in
Draft Environmental Management PlanCastle Hill Wind Farm
40
11. Site Rehabilitation and Reinstatement
11.1 Overview
The construction of the CHWF will be progressive in nature and post construction
reinstatement of all disturbed areas will also occur in a progressive manner, and in
accordance with the measures proposed within this EMP and relevant SEMPs. This
sequential reinstatement process will occur from upstream areas moving through to
downstream areas. The reinstatement process will ensure that all areas, including any
earthworks batters, internal roads, channels and sedimentation ponds are appropriately
stabilised before the Contractor demobilises from that particular area within the Site.
Reinstatement and revegetation will focus on providing a stable landform and vegetativecover promptly after the infrastructure is no longer required, or when the earthworks activity
is complete. Once construction activity is completed in a particular cluster or area, the
following activities shall be undertaken:
• All building and construction materials shall be removed from the Site and
disposed at a licensed facility.
• Temporary facilities such as contractor compounds, concrete batching plants
and erosion and sediment controls shall be removed from Site
•
Reinstatement will involve the stabilisation and rehabilitation of disturbed areasby ripping, top soiling, and revegetating the area.
• Follow up maintenance will be undertaken until the area is satisfactorily
stabilised and restored.
• The appropriate Council shall be notified.
Retention of topsoil for use in rehabilitation will form an integral component of the
rehabilitation process. In all areas of excavation, topsoil will be removed and stockpiled for
later use in the rehabilitation and revegetation of disturbed areas.
11.2 Revegetation
The objective of revegetation and rehabilitation will (apart from where there are non-
vegetated solutions proposed) be to replace vegetation as like-for-like. To assist vegetation
establishment, stock will be excluded from recently established grass and indigenous
plantings, with measures for control of pest animals and weeds undertaken to improve
establishment success. The control of pest animals and weeds will be provided for within
the Revegetation Plan (Appendix L) and within other relevant Biodiversity Management
SEMPs such as the Weed Hygiene and Surveillance Plan (Appendix M). A combination ofmethods may be utilised and are identified within this section.
Draft Environmental Management PlanCastle Hill Wind Farm
41
11.2.1 Hydroseeding
Hydroseeding will comprise the application of a mixture of grass seed, fertiliser and a
binding agent (usually wood or paper pulp) sprayed onto steep or otherwise critical exposedareas. Surface roughening exposed areas will aid vegetation establishment in hydroseeded
areas. Because hydroseeding does not retain moisture as well as topsoil, grass seed and
mulching, the timing of spraying important.
The benefits of hydroseeding are that it offers a solution to revegetate difficult terrain which
cannot be established by using normal methods. It is anticipated that the seed mix to be
used in hydroseeding will include perennial ryegrass, brown top and clover. The seed mix
must be free of weed seeds and will take account of the preferences and recommendations
of CHWF landowners.
Due to the steepness of the areas proposed for hydroseeding, Genesis Energy will require
that a uniform hydroseeded cover is provided. Areas being hydroseeded shall be inspected
six to eight weeks after the application and any areas that have failed to establish shall be
retreated until in excess of 80% cover is achieved and the area is deemed to be inherently
resistant to erosion
11.2.2 Direct Drilling
Direct drilling is a method of establishing pasture cover over large areas where suitable
contour allows for machinery to manoeuvre. In areas that are to be direct drilled, preparation
may include light cultivation and rolling to assist in pasture establishment. In areas capableof being direct drilled, the expectation is that the area can be fully reestablished into pasture
cover (100% cover). Depending on the prevailing climatic conditions, the normal timeframes
to observe successful establishment of vegetative cover is approximately six weeks. All
areas will be reviewed six to eight weeks after direct drilling to determine the overall
success of the established pasture and to enable resowing to occur in areas which have not
successfully established. A range of species will be used for revegetating the Site, with
pasture grasses including perennial ryegrass, brown top and clover where appropriate.
11.2.3 Fascining
Fascining involves the laying of seed-bearing slash or mulch branches with viable seed that
has been harvested from plants and placed across the slope to retain sediment. Often this
needs to be held in place with stakes or biodegradable netting. Seed contained on the
material germinates under the protective leaf mulch and establishes. The species likely to
be used for fascining activities at the CHWF Site are manuka and kanuka. Seasonal
considerations are necessary to ensure foliage collected contains viable seed.
Draft Environmental Management PlanCastle Hill Wind Farm
42
11.2.4 Direct Planting
Direct planting will use plants that are naturally found in the project area and are suited to
the Site. In order to reinstate or provide establishment phase indigenous vegetation cover,species such as kanuka, toetoe, manuka, karamu, ti kouka, piripiri and coprosma will be
used initially. Secondary phase indigenous species will be planted (known as enrichment) in
the appropriate areas once the initial canopy cover has been established. Slow release
fertiliser and water crystals will be used where necessary to assist vegetation
establishment. The areas proposed to be revegetated will be determined and set out in the
relevant SEMP, with appropriate species, the composition of the planting mix, plant spacing,
plant sizes and maintenance requirements.
11.2.5 Natural Revegatation
Natural Revegetation relies on the existing seed bank within soils and surrounding
vegetation to naturally establish or colonise areas. Natural revegetation of areas can be
enhanced when topsoil is collected from an area with a significant seed bank and spread to
an area identified for revegetation (e.g. not stockpiled).
11.2.6 Maintenance of Revegetated Areas
Ongoing maintenance in the form of pest and weed control, replacement of vegetation
which has failed to establish, and fencing will be determined for specific sites and set out in
the relevant SEMP.
Secure fencing or alternative protection will be necessary to prevent vegetation being eaten
by stock and to allow native plants to grow and or regenerate. Options for control of goats
and deer are being considered as part of a wider control effort within the CHWF properties;
however pests such as possums, hares and rabbits can cause considerable damage to
establishing vegetation and will require more focused control until vegetation has
established.
Weed control will also be undertaken in order to reduce competition from weeds for the
first 3 years following planting / sowing. Weeds will be suppressed by use of an appropriate
mulch or herbicide.
11.2.7 Stock Access and Farm Management
Construction activities will at times conflict with normal farm and stock management
operations within the CHWF, expecting the need to remove fencing and other containment
measures in order to undertake earthworks.
These aspects of the project will be managed in consultation with individual farm managers
and CHWF Landowners. In order to provide for stock containment, stock will be moved to
secure paddocks and fencing will be reinstated as soon as practicable.
Draft Environmental Management PlanCastle Hill Wind Farm
43
12. Air Quality
Various activities associated with the construction of the CHWF are expected to result inthe creation and discharge of dust into the air. The effects are expected to be less than
minor; however management measures will be employed as necessary. Management of the
effects caused by dust discharges will be covered in the ESCP(s).
12.1 Dust Control
To manage dust emissions from the CHWF Site during construction the following measures
will be implemented as appropriate:
• Temporary sealing of roads at key areas.
• Full compliance with the EMP and ESCP (Appendix F) and other relevant
management plans
• Temporary water application to suppress dust in certain areas or conditions
• Use of cement silos and aggregate bins to avoid aeolian dust.
• Provision of wheel washing facilities (where appropriate)
• Hydroseeding and other revegetation techniques will be applied to earthworks
sites as quickly as possible post excavation.
• Earthworks sites will be limited to areas of immediate construction.
• Restriction of traffic speeds.
• Vehicle tailgates will be properly sealed.
In addition, all stockpiles will be covered or stabilised to avoid loss of material during high
wind events and where practicable, placed in areas sheltered from the wind. Where a
significant amount of material is lost, a review of storage procedures will be undertaken to
avoid reoccurrence of the event.
12.2 Machinery and Vehicle Condition
Vehicles and machinery are one possible source of air contamination. All construction
machinery and vehicles operating on the CHWF Site will be in a good state of repair and be
Draft Environmental Management PlanCastle Hill Wind Farm
44
13. Construction Noise Management
The assessment of construction noise for the CHWF elements identified that theconstruction of the CHWF would readily comply with New Zealand Standard 6803:1999 –
Acoustics -Construction Noise. It was noted that during construction of roads, and in the
operation of construction vehicles over these roads there is potential to produce noise
levels which approach the limits of acceptability for construction noise. In order to ensure
compliance within the noise limits, and to address noise issues which may arise upon
commencement of construction a Construction Noise Management Plan (CNMP) shall be
prepared and implemented. The CNMP describes the manner in which noise effects will be
controlled to comply with the construction noise standard (except where appropriate forms
of mitigation have been provided), and to minimise noise effects on residents and other
noise sensitive activities near the Site. This CNMP includes a procedure for responding to
noise complaints. An outline CNMP is located in Appendix N.
13.1 Controlled Blasting
It is anticipated that the excavation work will be able to be undertaken entirely using
excavators and dozers with ripping attachments. However, it is possible that harder material
is encountered and that it may be necessary to undertake controlled blasting operations to
assist excavation activities.
Controlled blasting involves the breaking up of larger rock into smaller, more manageable
pieces. Rock drilling to plant the explosives is undertaken.
Any requirement for controlled blasting will be documented formally by the contractor in a
request to the Project Manager and Project Environmental Manager (or others as
necessary). The request will contain the following information:
• Name and qualifications of the responsible person(s)
• Current Approved Handlers Certification of the responsible person(s)
• Location of the area proposed for the discharge of the explosives
• Information on the method and explosive to be used and the depth and spacing
of the charges.
• The procedure for site clearance and post blast reoccupation
Draft Environmental Management PlanCastle Hill Wind Farm

15. Concrete Batching Plant Management
Up to four Concrete Batching Plant locations have been proposed On-site for the CHWFproject. The plants would be re-locatable with one or two locations concurrently operational
at any one time. Concrete Batching Plants may also be located next to water sources Off-
site.
A Concrete Batching Plant will consist of a concrete mixer, cement bins, sand and
aggregate stockpiles, water storage tanks and storage areas for equipment and tools.
Sufficient area is required for the use of front end loaders, delivery of materials and entry
and exit of agitator trucks. The Concrete Batching Plants will be approximately 5,600 m2 in
size.
Environmental management measures for the Concrete Batching Plant will be agreed in a
specific Concrete Batching Plant Management Plan (CBMP) (see Appendix I).
Draft Environmental Management PlanCastle Hill Wind Farm
47
16. Management of Quarries and Crushing Facilities
Potential gravel sources for concrete production and for construction of roads and otherhardstanding areas have been identified both On-site and Off-site. In order to use the
gravel, it will need to be quarried or excavated from the gravel source site.
An indicative quarry layout can be found in the Quarry Management Plan (QMP) located in
Appendix H.
The typical process for quarrying materials is as follows:
• Erosion and sediment controls will be established in accordance with the ESCP
and QMP.• Topsoil will be removed and stockpiled for use in rehabilitation,
• Overburden will be removed to On-site Excess Fill Areas
• Gravel resources will be excavated using earthmoving equipment. If hard
material is encountered controlled blasting may be necessary under strict
management.
• Gravel will be loaded into an adjacent crushing / screening facility.
• When the gravel deposit is exhausted, or gravel from that particular quarry is no
longer required the quarry site will be rehabilitated. This may include the use of
Draft Environmental Management PlanCastle Hill Wind Farm
48
17. Archaeological and Heritage Management
At the time of consent, no archaeological sites were known to be present and it wasconsidered unlikely that any unrecorded sites would be exposed during construction at the
CHWF Site. However, it is possible that items of archaeological interest may be discovered
as a result of exposing sub surface layers.
To address the potential for discovery items of archaeological interest, a comprehensive
Accidental Discovery Protocol will be developed in consultation with the tangata whenua.
This Accidental Discovery Protocol (ADP) will ensure that if koiwi tangata (human remains),
taonga or sub-surface archaeological evidence is uncovered during construction, work
would cease in the immediate vicinity of the remains so that appropriate action can be
taken.
Should an archaeological site be identified (through the CHWF construction process) and
the modification of such a site become necessary, an ‘Authority to modify an archaeological
site’ shall be applied for under Section 11 of the Historic Places Act 1993. No further work
shall be carried out that will affect the site until the appropriate permissions are granted.
This is in accordance with legal requirements. In addition, the tangata whenua shall be
consulted regarding the effects on Maori cultural values.
All Contractors working on the Site will be required to go through a Site induction process,
which will include training on the accidental discovery of cultural or archaeological sites or
material
A Draft Archaeological Accidental Discovery Protocol is provided in Appendix P.

18. Biodiversity Management
The approach to biodiversity management at the CHWF Site encompasses acomprehensive suite of measures that address effects to vegetation, habitats, flora, and
fauna through construction and operation of the wind farm. These are set out in a number of
SEMPs, each of which is summarised below and include for the mitigation of operational
effects.
18.1 Revegetation Plan
A Revegetation Plan will be prepared to ensure that rapid reinstatement of vegetation cover
following on from earthworks. The overall objective of this plan will be to ensure that vegetative cover (or alternative protective measures) is established within 3-6 months of the
completion of Site works. An outline of the Revegetation Plan is provided in Appendix L.
18.2 Habitat Management Plan s)
A Habitat Management Plan will be prepared for the CHWF, to enhance areas of indigenous
vegetation and habitat to improve the overall quality and productivity of that habitat. This
shall address matters such as legal and physical protection by covenant and fencing,
enrichment planting, revegetation planting (if required), natural regeneration, pest control,
and monitoring and reporting. It will guide the permanent protection and ongoing
improvement of an area of habitat approximately 210 ha in size, in a staged manner. An
outline of the Habitat Management Plan is provided in Appendix Q.
18.3 Riparian Protection Plan
A Riparian Protection Plan will be prepared to guide the physical protection of stream
riparian margins. It will establish the mechanism for the implementation of riparian protectionis achieved in a staged manner as the wind farm is constructed.
An outline of the Riparian Protection Plan is provided in Appendix R.
18.4 Weed Hygiene and Surveillance Plan
A Weed Hygiene and Surveillance Plan shall be prepared to promote good weed hygiene
and a high standard of weed control at the CHWF Site. This will address matters such as
transportation risks from vehicles or equipment and cover both terrestrial and aquatic pestspecies. The Weed Hygiene and Surveillance Plan is located in Appendix M and will require:

19. Visual Mitigation
Genesis Energy intends will minimise the landscape and visual effects arising from theinfrastructure at the CHWF by implementing the following:
• Siting Turbines within a defined Turbine Corridor which has been identified to
have acceptable environmental effects.
• Colour turbines off-white to light grey colour using a low reflectivity paint to
minimise visibility of turbines and reduce the potential for blade glint.
• Screen infrastructure (substations, buildings, etc) with appropriate vegetation to
‘soften’ built features in the landscape (where practicable).
• Use an appropriate colour palette for permanent buildings to assist in theirintegration into the landscape using colours recessive in nature, and appropriate
within the rural environment
• Investigate and where appropriate, implement site specific landscape mitigation
where it is considered that the occupants are likely to experience high visual
effects from their dwelling area.
• Work with the CAA and qualified landscape architect to reduce the effects of
light spillage (type, placement, colour) from turbines and other permanent
facilities.
Once wind turbine positions are finalised the assessment of shadow flicker effects will be
reassessed to confirm that predicted shadow flicker effects are less than the guidelines of
no more than 30 hours per year and/or 30 minutes per day. Landscape mitigation shall be
applied where high visual effects will be experienced from dwelling areas (where
appropriate).
Genesis Energy will minimise the landscape and visual effects arising from the earthworks
of the CHWF by implementing the following:
• Briefing construction staff on the desired approach to minimise environmental
impacts and proposed rehabilitation measures.
• Minimise extent of earthworks cuts and escarpments in road creation at final
design.
• Minimise height of earthworks cuts and escarpments at final design where
practicable.
• Engage a qualified landscape architect to assist in minimising visual impacts.
• Modify cut and fill to relate to the existing landform and natural features
• Store and reuse topsoil on finished earthworks to assist in revegetation.

20. Hazardous Material Management
A bulk storage facility (or facilities) shall be provided within a suitable location close to Siteoffices or active construction areas. Any facilities will not be located within 50m of a
watercourse. The bulk storage facility will be used to provide fuel to service all the vehicles
On-site, probably by way of mini tanker. Towable tankers may also be used in some
circumstances.
The bulk fuel tank will carry a significant capacity of diesel fuel. The tank will be double
skinned – providing an additional layer of containment should the inner tank rupture. This
tank shall be supplied and maintained by a specialist fuel supplier. Any towable tankers will
be stored in the bunded facility when these are not in use.
Spill kits will be carried in all fuel delivery vehicles (tanker trucks and towable tankers), and
be located at the contractors compound, project Site office, substations and any other
location deemed necessary.
Any fuels for hand held equipment, oils, lubricants and other hazardous compounds will be
stored in a secure facility within the contractor compound and O & M facility and in
accordance with all relevant guidelines and regulations. The small quantities of these
materials will be stored on bunded trays to prevent spillage. The following measures shall
also be required:
• The Contractor will ensure that all personnel using hazardous substances aretrained and qualified to do so.
• An incident report shall be prepared in the event of a spill/incident
• All unwanted materials and empty containers should be disposed of Off-site at
an appropriate landfill
• The Contractor Project Manager (or delegate) shall review and retain copies of
Material Safety Data Sheets (MSDS) which identify the specific requirements in
relation to storage, use and disposal of hazardous substances.
20.1 Contaminated Land
Due to the agricultural setting of the CHWF, there is the possibility of encountering old offal
pits, old sheep dip sites, rubbish pits, metals and other contaminants from historical
pesticide/fertiliser use, spills of fuel or other from storage tanks, effluent pits, and asbestos
in buried building materials. During the various investigations and consultation performed at
the CHWF, no evidence of contaminated land of any type was identified.

57
21. Operations and Maintenance Environmental Management
The CHWF will be operational over an indefinite period. Activities On-site during theoperational phase are of significantly lower intensity than during construction, therefore a
detailed management approach for the operational phase requirements of the wind farm is
not considered to be required at this stage.
21.1 Operational and Maintenance Activities
At the end of construction, works will be stabilised and structures completed or
disestablished, and activities will be limited to those required for the long term operation of
the wind-farm. Key operational activities are identified below.
• Wind farm operation – i.e. control and scheduling of electrical equipment, and
dispatch of power.
• Repairs and maintenance activities:
o Turbine maintenance, e.g. regular servicing, including changes of
Draft Environmental Management PlanCastle Hill Wind Farm
61
21.2 Transport Activities
Operational transport activities will involve limited day to day access by wind farm staff and
contractors together with occasional delivery of supplies and components. There may alsobe times when major turbine component replacement is necessary. At these times, the level
of activity and the duration of those activities will vary depending on the type of major
component replacement. Transport requirements will include a requirement to import
OW/OD loads, involve increased staffing and possible disruption to traffic.
Civil maintenance of Internal Roads and Turbine Platforms are expected to require
infrequent grading and restoration of roads and Turbine Platforms or their drainage systems
to maintain the level of intensity required for normal operations activities. These activities
will be intermittent, internalised and will be performed on a scheduled basis.
21.3 Wastewater Management
Toilet facilities will be provided On-site, with holding tanks or septic tanks utilised. Sewerage
will be removed from Site and disposed of at a licensed waste treatment facility in
accordance with the manufacturer’s recommendations and the level of utilisation.
21.4 Operational Noise Management
At all dwellings, the sound levels predicted from operational activities from the CHWF can
comply with the limit recommended in NZS6808:2010. To ensure compliance is achieved,
and to address noise issues which may arise upon commencement of the operation of the
wind farm, the following measures are proposed:
• That noise emissions assessed by NZS6801, NZS6802 and NZS6808, will
comply with limits in the District Plans and with those derived by the method in
NZS6808:2010 as appropriate.
• The noise assessment presented in the AEE will be reviewed prior to theconstruction of the CHWF. This will include a recalculation of the CHWF sound
output once the wind turbine selection has been determined and their operating
parameters are known, and their siting location has been determined. The
outcome of this will be the production of an Operational Noise Assessment
Report, in which it shall be demonstrated that the noise limits of NZS6808 or of
resource consent conditions will be met.
• The sound character of the selected turbines should also be assessed once the
first turbines are installed and commissioned, to ensure that special audible
characteristics are not present, and to allow the manufacturer to rectify any
such problems before the remainder of the CHWF is constructed.

22. Incidents
All environmental incidents will be recorded and immediately reported to the Project
Environmental Manager within 24 hours of the incident occurring. The Environmental
Manager will determine the need and timing for reporting the incident to the Councils.
The need for and timing of reports will depend on the seriousness of the incident, Where an
incident or potential incident occurs that is likely to cause significant Off-Site effects on
people or the environment a report shall be supplied to the Council detailing the relevant
facts within 48 hours of the incident occurring. A further detailed report outlining
investigations of the causes and identification of additional preventative measures shall be
submitted to the Councils within 14 days of the incident.
All personnel will be made familiar with the CHWF Contingency Response Plan (below),which identifies objectives and actions to be taken in the event of an environmental
emergency. If a significant ecological, social or heritage event occurs as a result of any
project activity, works in the immediate area will cease and the Project Environmental
Manager will be advised. Consultation with Council will be initiated, experts or individuals
will be engaged to assess the extent of the impact, and a plan for remedial action will be
developed. Remedial work will be undertaken as required and may be subject to inspection
from the Councils.
The incidents register will be kept at the Site office. All personnel working On-site are
required to report any incidents.
22.1 Incident Response Plan
If an environmental emergency or incident occurs On-site, prompt remedial action will be
implemented. Once the situation is controlled and addressed, a review will be undertaken to
assess the effectiveness of the remedial actions employed. The EMP will be updated to
reflect the outcome of any reviews.
Unforeseen events which may result in emergency action being undertaken include:
• Natural Hazards such as earthquake, flooding, extreme rainfall and wind events
Draft Environmental Management PlanCastle Hill Wind Farm
65
• Identify the issue which is contributing to the discharge.
• Take all practicable steps to improve the quality of the discharge, including:
o
Unblocking any sediment control deviceso Use an approved flocculant in accordance with the ESCP
o Increase detention time in sediment ponds where practicable
o Preventing discharge by blocking discharge outlets
o Determine measures to remove deposited sediments
• Undertake a review of the failure to identify any requirement for repair,
replacement or redesign – such as:
o Increase size of sediment control devices
o Installing additional sediment control devices
o Increase diversion of clean water around exposed surfaces
o Mulch exposed surfaces
The Environmental Project Manager shall notify Council at the earliest possible convenience
to advise of the incident and the proposed approach to mitigating the discharge should
appropriate mitigating measures be appropriate or available.
Where sediment discharges prevent the use of domestic water supplies, an alternative
temporary water supply will be installed and maintained by Genesis Energy until the originalsupply is fit for purpose and consumption. This is likely to consist of providing a tank and
tanker supply to the affected areas.
22.4 Fire
Equipment such as fires extinguishers and fire blankets will be located in the Site office and
within all contractor vehicles. Water carts will be located On-site and will assist with
extinguishing a fire. If a fire cannot be extinguished immediately, the Fire Service shall be
contacted. The Project Manager and Environmental Project Manager will determine thesafety of all persons and property in determining the immediate fire response.
The New Zealand Fire Service will be provided with layout details of the wind farm, including
access points, road network and the location of water sources.
22.5 Noise
Should noise generated from the CHWF and associated operations be the subject of
complaint, the noise generating activity will be reviewed in accordance with relevant
Draft Environmental Management PlanCastle Hill Wind Farm
66
standards by the Environmental Project Manager and Project Manager and a decision be
made as to weather to stop that activity.
A review will be undertaken to identify why the activity is considered to produce excessivenoise and if there are practical options to reduce the noise generated or remediate the
noise producing activity. Such options to be considered include:
• Undertaking the activity under alternative climatic conditions
• Undertaking the activity in an alternative location
• Reducing the number of activities being undertaken at any one time
• Using noise barriers to muffle sound
• Repair any damaged or faulty equipment generating the noise.
22.6 Air-borne Particles
Should particles such as dust, cement or other contaminants be identified, measures will be
taken to eliminate the source. This will be achieved by applying water to the source of dust,
covering loads or exposed areas.
Once the situation is remedied, the incident will be investigated to determine how the
situation can be avoided or mitigated going forward.

23. Inspection, Monitoring and Auditing
The system for reviewing the environmental performance of the project activities will be
based on regular inspections, audits and sound environmental monitoring programs. These
aspects are discussed in more detail in the following sections.
23.1 Inspections
During construction, weekly inspections will be undertaken by the Contractor and Genesis
Energy Environmental Project Manager to achieve fine scale monitoring of specific
environmental aspects to ensure compliance with the EMP, SEMPs and the relevant
resource consents.
An indication of the environmental aspects requiring monitoring and the frequency of
inspections are presented in Table 8 below. This list is not exhaustive and may be amended
as specific environmental issues arise. In addition to the targeted inspections detailed
below, the contractor will have the responsibility of identifying any non-compliance with the
EMP and SEMPs.
Table 8: Environmental Inspections
Environmental Aspect Frequency as
appropriate)
Erosion and sediment controls – Ensure there are no significant erosion /sedimentation events caused by inadequate maintenance of soil / watercontrol devices
As provided inthe SEMP
Culverts – Ensure the culverts On-site remain free from debris and fishpassage is not restricted
Weekly
Hazardous materials and waste – Ensure all hazardous material and wastestored and handled as per the EMP and the statutory requirements
Weekly
Roads – Road conditions meet required standards and ensure the safetransportation of required material On-site.
Weekly
Site remediation – Stabilisation and revegetation works are successful with nosignificant plant loss
Weekly
Biodiversity – Ensure the no-go zones are left undisturbed. Inspections will alsolook for signs of dieback due to dust or root compaction, weed infestationsand plant disease.
As provided inthe SEMPs
The effectiveness of the inspections will be reviewed and where necessary, the level, scope
and timing of inspections will be improved through the life of the project to ensure the
project achieves the required environmental performance.
Draft Environmental Management PlanCastle Hill Wind Farm

23.2 Monitoring
Genesis Energy has proposed a range of measures and environmental monitoring to
appropriately address the potential adverse effects of the CHWF development.Management of the CHWF during both the construction and operation phases revolves
around the establishment of this EMP and the associated SEMPs.
In addition, Genesis Energy or its representative(s) will closely and regularly monitor the
construction works. Work will require formal notice to proceed. This notice will not be
issued to the contractor unless Genesis Energy is satisfied that appropriate, compliant
measures to avoid potential adverse effects are either in place or shall be undertaken in
accordance with the management plans, or if not practicable, planned to occur during the
works.
23.3 Auditing
Auditing of performance is central to confirming that the environmental management
measures proposed are implemented, effective and maintained. It is appreciated that
Council representatives will have a role in monitoring and auditing the project so that it is
proceeding in compliance with resource consents. In addition to Council monitoring and
auditing (where Genesis Energy will work closely with the Council representatives), Genesis
Energy will have its own audit procedures to ensure that the Contractor engaged to
construct the CHWF is undertaking its work in consistency with Genesis Energy’sEnvironmental Values.
The Project Environmental Manager will be the lead Genesis Energy representative to audit
and inspect works to determine if the contractor is undertaking these in accordance with the
EMP and SEMPs. The Genesis Energy Project Environmental Manager will also undertake
periodic audits in response to complaints and incident management.
23.4 Non-compliances
A Non-compliance Report will be generated when:
• A complaint is received regarding any environmental impact or aspect caused
by the project, provided initial investigations show the complaint is valid.
• A departure from approved or agreed environmental procedures is observed.
• A non-compliance is identified as a consequence of any self assessment, formal
audit or other environmental survey or inspection.
Any complaints received will be recorded by the Project Environmental Manager in the
Public Enquiry Record and registered with the Site Manager. The Record shall include thedetails of the complainant, date, nature of complaint, weather conditions at the time of the
event (if relevant), corrective action and follow up with the complainant. The record will be
kept at the Site office and included in the weekly and monthly reports.
If a material complaint is received the Councils will be notified within 5 days.

25.2 Inspection and Audit Reports
As outlined in Section 23 regular inspections and audits will be undertaken and
documented. Inspection reports and associated environmental documentation will beavailable at the Site office. Subsequent details of corrective action and results will also be
available.
25.3 Weekly and Monthly Reports
Weekly and monthly reports will be prepared by the contactor and be made available to
relevant stakeholders. The contents of the reports would include at minimum:

The Universal Soil Loss Equation (USLE) would be utilized. This assessment willprovide an initial justification to the proposed sediment and erosion control devices
that will be used to manage and mitigate the effects. This would be confirmed with
the operational experience offered by Genesis Energy’s consultants, contractors and
Council reviewers.
As well as USLE methods, degree of risk can be classif ied into three key categories,
which are:
• Sediment generating potential - this highlights the generation potential of the
area in question and is based on slope, slope length, soils, rainfall and erosion
control factors.
• Sediment delivery – this relates to the amount of eroded material that is
retained on site in depressions and within the site’s natural contours prior to it
entering any sediment treatment devices.DR
A FT
• Sediment yields – the amount of sediment that actually leaves the site and
enters the receiving environment. It is well recognised that this is the key
area of interest.
Discussion of each of these categories will be prov ided in relation to the methods
proposed.
5.0 Overall Erosion and Sediment Control Approach
The following section will provide an outline of the key measures that will be
implemented as part of the ESCP for the phase of work being considered and builds on
the principles outlined in Section 2.0.
5.1 Team Approach
This section will outline the parties and personnel involved in developing,
implementing, monitoring and modifying the ESCP. This will include Council, Genesis
Energy consultants/contractor, and Genesis Energy staff. This section is included to
demonstrate that adequate resources, commitment and expertise are provided to
effectively implement erosion and sediment controls from start to finish of the Project
(design through to dis-establishment).
A key focus of this section wil l be how effective communication will occur. Discussion
on how information, reports, data will be disseminated amongst all the required
parties will be provided.
5.2 Erosion and Sediment Control Device and Measures
This section will provide a brief summary of what erosion and sediment control
measures will be used to minimise the extent of soil erosion and sediment yield in the
area of the site being considered. This will draw from the toolbox of methods set out
in the PDP Hydrology Effects Assessment.

C A S T L E H I L L W I N D F A R M E R O S I O N A N D S E D I M E N T C O N T R O L P L A N
This section will include both engineered (device orientated) and management options(such as staged works, timing of works etc). The section will not get into the specific
detail for each individual device (this comes in section 6), the purpose of this section
is more to state how the device designs will generally conform to meet WRC’s erosion
and sediment control guideline.
5.3 Monitoring
This section will be broken into two types of monitoring; performance monitoring of
device effectiveness, and site monitoring for assessing current and new risk.
Within each of these types of monitoring, discussion will be provided on how the
monitoring results will be reported, evaluated and where appropriate actioned (eitherthrough changes to the monitoring strategy or site erosion and sediment control
improvement). DR
A FT
For device performance monitoring, discussion will be provided to demonstrate that
the erosion and sediment control devices have been installed correctly and are actually
working as intended. This monitoring section will need to demonstrate what
procedures will be used throughout the entire period of construction.
Discussion of the performance monitoring information of erosion and sediment control
devices will be provided.
Discussion of how monitoring will be undertaken; such as grab samples, laboratorymethods of analysis, reporting of monitoring results, and how monitoring results will
be evaluated and where appropriate, the monitoring methodology altered, will be
provided.
In parallel to device monitoring, receiving environment monitoring of freshwater and
freshwater habitat monitoring will be included.
The monitoring section will also include how continued assessment for risks will be
undertaken i.e. risks that were not identified initially, but may become apparent over
the construction period. This is essential to cover the principle regarding plan
evolution and improvement. Discussion on what mechanisms will be in place to
incorporate newly identified risk into the ESCP will also be provided.
5.3.1 Response to Indicators of Significant Effects
In this section, discussion will be made as to how parties will respond to adverse
events and what measures will be in place if adverse effects are detected.
This section will include discussion that should linkages between the adverse effect
and on-site erosion and sediment control practices be found, then alterations to the
operational methods (including modifications to environmental control measures and
methodologies) will be investigated as a first order response.

1.0 Introduction
This section will provide a high level discussion summarising the purpose of the
Drainage Management Plan (DMP) and how the DMP plays a part in the wider suite of
management plans for the Castle Hill Wind Farm (CHWF) Project.
The introduction will include discussion of the process to be followed in development
and implementation of the DMP:
• that Genesis Energy’s consultants will prepare the drainage detailed design
plans for each individual device or structure as per the direction provided by
this DMP and the Consent.
DR
A FT
• that these detailed design plans will undergo a consultation/review process
with Council.
• that once agreed and consented, the drainage network will then be
constructed.
• that Genesis Energy will be responsible for managing the operation and
maintenance requirements of the drainage network as directed by this DMP.
1.1 Purpose
The purpose of the DMP is to outline the proposed designs for proposed permanent(operational phase) drainage devices and structures for the Castle Hill Wind Farm
(CHWF) project. This includes, but is not limited to:
• Outlining the proposed infrastructure that will used to manage stormwater
effects (flooding and water quality management) during the operational phase
of the CHWF Project.
• Provide details as to how the proposed infrastructure will be designed,
operated, maintained, and monitored to ensure that stormwater effects from
the project are appropriately managed.
The DMP may be developed progressively in line with future construction phasing ofthe CHWF.
1.2 Objectives
The following objectives will be used in the development of the DMP.
• The use, as a minimum, of the methods promulgated through the Hydrology
Effects Assessment (PDP, 2011) and any outcomes defined through the
required statutory process.
• Demonstrate how the designs and methods promulgated are the Best
Practicable Option and meet the design requirements.

• To minimise any potential adverse environmental effects on water quality and
aquatic ecosystems from the proposed stormwater discharge from the Project.
• To minimise any potential adverse environmental effects from flooding or
erosion (inclusive of land or watercourses) from the proposed stormwater
discharge of the Project.
Any specific consent conditions relating to drainage wil l be identified here.

This document is the Construction Traffic Management Framework for the Castle Hill Wind Farm.
It has been prepared to set out the purpose, objectives and specific standards to be applied when
preparing the Construction Traffic Management Plan (CTMP) at the detailed design stage.
Some aspects of the construction methodology are to be fixed as specific standards in this
Framework which must be included in the CTMP under the conditions of the resource consent for
the CHWF. Other aspects, such as timing and staging (which influence traffic volumes), are to be
developed at the detailed design stage when contractors are involved. It is not practical to
prepare these details at this stage, and the approach of preparing the full CTMP at the detailed
design stage will enable contractors to bring innovation where appropriate, enabling a
substantially better outcome for other road users, the efficiency of construction, or both.
The CTMP is to be prepared by a Chartered Professional Engineer with specialist skills in Traffic
Engineering and Transportation Planning, appointed by the consent holder. Preparation of theCTMP will involve input from the principal civil engineering contractor, the turbine transport
contractor, Tararua and Masterton District Councils, residents on the transport route who wish to
be involved, emergency services and local transport operators (such as the school bus operator
and livestock transporters). It will be required to meet the purpose, objectives, and specific
standards set out in this Framework. The Plan is to be submitted to the Councils to be assessed
and certified as meeting the requirements of the Framework.
2. Purpose and Objectives
2.1 Purpose
The purpose of the CTMP is to set out in detail the manner in which construction traffic will be
managed to ensure the safe and efficient performance of the road network, to minimise adverse
effects on the existing community arising from construction traffic, and to provide the community
with information about Genesis Energy’s traffic arrangements.
2.2 Objectives
The objectives of the CTMP are to:
(i) ensure the specific requirements of Acts, Regulations, Bylaws and consent
conditions in relation to construction traffic, are adhered to;
(ii) encourage a culture of road safety awareness and commitment;
(iii) ensure best practice in transport safety;
(iv) ensure emergency services are not obstructed;
(v) minimise disruption to the community, farming operations and rural services;
(vi) minimise traffic generation; and
(vii) encourage the participation of the community in maximising safety and minimising
disruption.
Genesis Energy, Castle Hill Wind Farm: Construction Traffic Management Framework
These objectives will be achieved by the methods set out in the CTMP.
3. CTMP Development Process
Preparation of the CTMP will be facilitated by a Chartered Professional Engineer, specialising in
Traffic Engineering and Transportation Planning, appointed by the consent holder. Its
preparation is to begin approximately four months before construction.
In preparing a first draft CTMP, the Chartered Professional Engineer shall:
(i) review this Construction Traffic Management Framework;
(ii) review the CHWF Transportation Assessment and relevant evidence;
(iii) review the approved consent conditions;
(iv) liaise with the consent holder, the lead civil engineer, the principal civils
contractor, the turbine transport contractor, Tararua and Masterton DistrictCouncils, residents on the transport route who wish to be involved, NZ Police, NZ
Fire Service, St Johns Ambulance, the school bus operator, rural transport
operators (identified by residents), and vets.
Liaison may involve such meetings and conversations as are appropriate to ensure effective
consultation with the parties listed above, and others considered appropriate by the Engineer.
The first draft will be circulated to the above parties for comments and suggestions. A period of
at least four weeks will be allowed for comments and suggestions. These will be evaluated by
the Chartered Professional Engineer and incorporated into the completed CTMP, as the Engineer
determines appropriate.
The completed CTMP will be submitted to the Tararua and Masterton District Councils at least
four weeks before construction of the CHWF begins along with a report outlining the comments
and suggestions made on the first draft, and the extent to which they have been included. The
Tararua and Masterton District Councils will assess the completed CTMP with a view to certifying
it as meeting the purpose, objectives, and specific standards set out in this Framework.
Any changes required to achieve that certification will be discussed between the Councils and the
Engineer and made, enabling the final CTMP to be distributed to:
(i) the consulted parties;
(ii) rural transport operators and rural service providers who regularly use the primaryaccess roads; and
(iii) made available to residents and others who have an interest via electronic media.
Updates will likely be required from time to time as a result of project changes or issues arising,
which may be identified by the consent holder, its contractors, Tararua or Masterton District
Councils, or to address matters relating to residents or other road users. Suggested changes to
the CTMP or issues arising will be referred to the Chartered Professional Engineer who will
consider the matter and make a recommendation to the Tararua and Masterton District Councils.
If the Councils certify the recommended changes to the CTMP, revised copies will be made
available via digital media for the above referenced parties.
Genesis Energy, Castle Hill Wind Farm: Construction Traffic Management Framework
The CTMP shall be prepared in consultation with event organisers and Councils. It shall have
regard for but not be limited to considering the following:
(i) car rally and/or cycling events;
(ii) other activities and works within the road environment that may occur from time to
time;
(iii) the movement of stock along or across the roadways;
(iv) ram sales and mustering which typically occurs in November;
(v) lamb sales which typically occur around February; and
(vi) fertilising activities in autumn and spring. Of note in this regard is the Daggs Road
access to the airstrip, which appears to service up to about seven farms.
4.8 Travel Plan
A Travel Plan shall be developed to minimise contractor generated traffic and construction traffic
movements to and from the Site. This shall consider for example alternative travel modes, off-set
travel times, ride sharing and opportunities for back loading of construction vehicles.
4.9 Driver Protocols
In addition to the driving standards imposed by law, all drivers involved in the project will besubject to additional protocols when travelling along the district roads. The objective of these
protocols will be to ensure the safe operation of roads and to minimise existing user delay during
construction.
The CTMP will set out these protocols along with the monitoring and disciplinary procedures to be
followed in the event of any breaches.

Draft Environmental Management PlanCastle Hill Wind Farm
Appendix Y: Operational Noise Management Plan ONMP)
Purpose
The purpose of this Operational Noise Management Plan (ONMP) is to describe the means
by which noise effects arising from the operation of the Castle Hill Wind Farm (CHWF) will
be avoided, mitigated or remedied, to describe the means of monitoring compliance with
noise conditions, and to describe a mechanism by which any noise complaints related to
Operation will be received and addressed.
Objectives
The objectives of this ONMP are as follows:
• Describe the noise limits which apply to noise sensitive locations near the Wind
Farm.
• Describe the activities which will produce noise at dwellings, and describe the
likely noise levels times for which this will occur.
• Describe the method of monitoring noise levels to ensure that noise limits are
met.
• Designate persons responsible for liaising with the community, both to inform
the community of operational activities and to receive and respond to any
complaints.
• Describe a procedure for response to complaints.
• Describe the responsibilities of the Wind Farm operator in reporting to the TDC
and MDC.
Proposed Content
Noise Limits
The noise limits which apply to this Wind Farm are described in detail in the FinalOperational Noise Assessment Report (FONAR). In general the limit on noise from wind
turbines is 40 dB LA95 at the notional boundary of dwellings, although at x specific
locations this limit rises with increase wind speeds as discussed in the FONAR.
Noise from vehicles on Site and fixed plant including substations and etc are those
described in the Conditions of Consent, which relate to the permitted activity noise limits in
Draft Environmental Management PlanCastle Hill Wind Farm
Noise is produced by wind turbines when they operate, with noise output level depending
on wind speed. The wind turbines used in the CHWF are xxx model yyy which produce a
peak noise output of xx dB Lw. The turbine operate in the wind speed range of xx and yy.The operational mode of the turbines are xx during condition A and yy during condition B.
Substations
On-site Vehicles
Maintenance Facility Activities
Others as Applicable
Noise Monitoring
Noise monitoring for compliance testing purposes shall be carried out within xx months of
the completion of the Wind Farm, [or of each stage of the wind farm… details to be
determined]. All noise monitoring shall be carried out in accordance with the relevant
clauses of NZS6808:2010, and compliance testing shall be reported in accordance with the
requirements of that standard.
Liaison
Ongoing communication between the Council and the Community and Genesis Energyforms a useful part of the management of noise effects and provides input into any future
review of consent conditions.
Complaint history shall be maintained by TDC and MDC and made available for
consideration upon request.
A 6-monthly newsletter shall be placed in the local newspaper by Genesis Energy during the
first two years of operation. The newsletter shall include updates on the development and
operation of the wind farm, results of compliance testing, and shall provide contact details
for the Community to communicate with Genesis Energy.
Complaints Procedure
Any noise complaints may be directed to the Community Liaison Manager.
Complaints shall be responded to within 24 hours. The response shall include an
investigation of the noise produced at the time of the complaint, and if compliance with
consent conditions is uncertain, shall be accompanied by a noise assessment to determine
what, if any, additional mitigations should be implemented.
The result of the noise assessment shall be reported back to the complainant within xxhours of a determination of the response.
Draft Environmental Management PlanCastle Hill Wind Farm
Procedures for Investigation of Complaints
Prior to the receipt of Compliance Testing Report
Complaints may be received in the first months of operation of the Wind Farm, prior to the
completion and reporting of compliance testing. These complaints may be relevant to
compliance testing, and Genesis Energy shall direct its noise consultant to have regard for
these complaints and the conditions in which they arise in the compliance assessment.
Within three working days of receipt of such a complaint Genesis Energy shall provide a
written or emailed response to MDC and TDC advising that this information has been
provided to its noise consultant, and an estimate of the date of completion of the
Compliance Testing Report, or any other relevant information about the status of
compliance testing.
The Compliance Testing Report when submitted to the Councils shall include a section
discussing complaints received, and describing the actions taken to incorporate these
complaints into the assessment methodology.
Following the receipt of Compliance Testing Report demonstrating compliance)
Complaints received after the Wind Farm has been demonstrated to be compliant with
Consent Conditions may arise from one of two causes:
1. Operational conditions exist which were not considered in the assessment of
compliance. This may include a change in noise emissions due to wear or failure of
turbine components, or meteorological conditions which were not foreseen, or
some other change to the wind farm.
2. Resident satisfaction is not addressed by confirmation of compliance with consent
conditions.
On receipt of a complaint it may not be possible for the Council to determine which of these
two categories the complaint falls into. When each complaint is passed to Genesis Energy,its first response shall be to report the wind direction, wind speed, and number of
operational turbines at the time of the complaint to the Council, and to provide a statement
as to whether this set of conditions has been demonstrated to be compliant.
Where conditions arise which have not been considered in the Compliance Testing Report,
a suitably qualified and experienced person shall be engaged to assess compliance under
these conditions. The results of this assessment shall be provided to TDC and MDC. If non-
compliance is demonstrated, remedial steps shall be undertaken as described in the
following section. If compliance is demonstrated, then this condition shall not be required to
trigger such an investigation following future complaints under similar conditions.
Draft Environmental Management PlanCastle Hill Wind Farm
If a number of complaints are received during a specific period under a condition which has
previously been shown to comply, the Council may request Genesis Energy to provide
evidence (for instance by comparing sound levels near the turbines to those levels
produced during compliance testing) that the wind farm noise output has not increased aftercompliance testing was carried out.
If a significant increase is demonstrated under the wind conditions in question, the Council
may request that compliance testing be repeated for that wind condition. If the sound level
has not increased by more than 2 dB, then the relevant complaints may be considered to
belong to category 2 above. In this latter case the complainants shall be informed that the
wind farm has been deemed to be operating within its consent conditions, but that the
complaints have been permanently logged and will form part of the complaints record.
Following receipt by Councils of the required description of operational conditions and
intended actions by Genesis Energy (including a timeframe for these actions), a written
response shall be provided to each complainant describing this action. This response shall
be provided within one week of the complaint. It is acknowledged that if the noise event is
caused by unusual meteorological conditions, the timeframe for assessment of that
condition may be dependent upon these conditions re-occurring.
Remediation Measures
Should non-compliance be demonstrated, the operation of the wind farm shall be ceased or
modified until modifications are made to reduce noise. These modifications may include
modifications to turbines, cessation or modification of operation of certain turbines duringcertain wind conditions, or improvements to sound insulation at affected properties, or
other treatments.
Resumption of operation shall be subject to the demonstration of compliance. Prior to the
re-commencement of operation, a report shall be provided by Genesis Energy to
TDC/MDC describing the remedial steps taken and demonstration of compliance.
This information shall be reported to the complainant(s) who were affected by the original
