5 PROJECT DESCRIPTION The Turitea Wind Farm Project is to be situated in the Turitea Reserve and on adjacent privately owned farmland. The existing South Range Road (SRR), running from the Pahiatua-Aokautere Rd (Pahiatua Track) in the North southward along ridgeline on the Tararua Range will serve as the main access way through the wind farm. On the western side of SRR, the site is predominantly Turitea Reserve land and forms the catchment area for the Palmerston North City Council (PNCC) water supply. This land has mixed vegetation with some tussock grass, forestry, recovering forested areas and native bush covering the ground. On the eastern side of SRR, the site is predominantly grazing farmland (agricultural landuse). All Wind Turbine Generator (WTG) sites will be accessed from SRR via either short distance lateral access roads or two longer access roads heading in a westerly and easterly direction. In some instances, existing unused forestry track alignments will be upgraded to form access roads to the WTG sites. The location of each WTG is shown in Figure 1 below. Two new site entrances off Pahiatua-Aokautere Road, will be constructed for site access. The main construction entrance will be situated on the western side of the existing SRR entrance and will become the new permanent SRR entrance. A secondary construction entrance off Pahiatua-Aokautere Road will be situated on the eastern side of the existing SRR entrance and this will predominantly be utilised for haulage of the WTG blades to each WTG foundation site. Blade lengths will prevent the haulage of the blades through the main construction access. Figure 1 â&#x20AC;&#x201C; Turitea Wind Farm Turbine locations

7 MANAGING ENVIRONMENTAL RISKS 7.1

On-site training

To ensure a high level of compliance, all staff will be educated in environmental compliance issues and the project environmental risk register. A comprehensive environmental induction will be provided to all staff and subcontractors prior to starting work on site. The induction will include information on the ecology of the area, heritage issues including procedures and protocols in the case of accidental discovery of archaeological sites, and the requirements of the various consents. Information will be provided on environmental controls such as sediment control devices, noise, hazardous goods, spill minimisation and response, and dust mitigation measures and waste management.

Construction Environmental Management Plan Turitea Wind Farm TWF-PM-PLN-0011-05-CEMP

All Environmental issues will form a regular part of toolbox meetings to ensure all workers are aware of the key issues. The Environmental risk register will also be updated accordingly to capture new and evolving risks to project. Site staff will be made aware of any restrictions in operations when working near designation boundaries, on private land or potentially affected parties. All Contractor/s and their relevant sub-contractors, as a condition of their contract with the project, will be required to actively manage environmental issues associated with subcontracted works and comply fully with the Resource Management Act, project resource consents, all applicable statutory regulations, the CEMP, relevant SEMPs and other relevant management plans (or relevant parts thereof). All staff and subcontracted staff will be required to attend a project induction that will include a section on environmental issues and management.

7.2

Site Environmental Management Plans

Schedule 2, Condition 8, requires the following: The Consent Holder shall prepare and submit to the Environmental Compliance Manager, at each respective Council, a SEMP for each of the South Range Road, Water Catchment Access Road, Western Ridge, Browns Flat and Cross Valley Transmission and Out of Reserve (farmland) sub-catchment areas. The breakdown of the site into individual SEMPs may be varied by the Consent Holder as necessary to reflect any change to the design and construction programmes. However, as per the design changes in the ‘Approved Layout from the Board of Inquiries Decision’, Site Environmental Management Plans (SEMP) for the three sub-catchment areas identified in figure 3 overleaf are anticipated. These include: • • •

Back Ridge North - Labelled E on the approved layout and includes South Range Road Back Ridge South (North) - Labelled D on the approved layout and includes South Range Road Upper Pahiatua - Labelled C on the approved layout and includes South Range Road

Each of these sub-catchment areas have been reviewed and assessed to identify and mitigate against general environmental risks associated with the work programme. Due to the extent of similarities between all three areas, including the work programmes, an overarching SEMP has been created by Environmental Consultant Mike McConnell (McConnell Consultancy Ltd) to address potential environmental risks for all three. Once details of the specific design and construction methodology is confirmed, Site Specific Erosion and Sediment Control Plans (SSESCP) will be prepared and submitted for approval prior to works commencing. These shall be written in accordance with the relevant conditions of Schedules 1 and 2 of the consents. This staged submission of SSESCP’s is undertaken on most large earthworks project and has been found to be an appropriate method of managing this process. These SSESCPs will be peer reviewed by Southern Skies Environmental Limited (as required by Schedule 2, Condition 4). Detailed procedures for the inspection, monitoring and reporting of each of these sub-catchment areas is contained within the SEMP

7.3

Key Potential Environmental Effects

The key environmental risks from this project include dust, erosion and soil/ nuisance, sediment loss into local waterways and the PNCC water supply, soil and water contamination resulting from spills of hazardous materials, proliferation of weed and plant pests and impacts on local ecology and wildlife. Methods adopted to avoid or minimise these risks are summarised below.

7.3.1-Controlling Dust Emissions Potential sources of dust on the project include the following: • • • • • •

Wind entrainment from exposed surfaces; Dust from roads and access areas generated by trucks and other mobile machinery movements; Excavation and disturbance of dry material; Loading and unloading of dry materials to and from trucks; Stockpiling of materials including material placement and removal; Storage and handling of bulk cement.

Of these, the most significant sources of dust are likely to be from unstabilised, dry, exposed surfaces such as stockpiles, unsealed haul roads and open earthworks (excavations and embankments). This can be managed through: • • -

Minimising the extent of unsealed areas: Limit earthworks extent and vegetation clearance as much as practical Stabilise exposed surfaces as soon as practical and where they will be undisturbed for longer periods. Stabilisation can include metal, paving, polymer, hydroseed, mulch and permanent planting. Minimise the area of surfaces covered with fine materials Modifying the condition of the materials to lessen the tendency to lift with the wind or other disturbances such as vehicle movements: Water exposed surfaces and materials using water carts, sprinklers or manual hosing Ensure sufficient water is applied (i.e. enough water to prevent dust generation). Ensure sufficient water is available on site and consider locations of water bores/storage to minimise haul distances for water carts

In addition, daily forecast wind speed, wind direction and soil conditions should be taken into account before commencing operations that have a high dust emission potential. Further details of dust management are included within the SEMP – refer to Annex I for a copy of this plan.

7.3.2-Controlling Soil/Sediment Loss Potential sources of soil/sediment loss on the project include the following areas: • • •

Cleanfill sites or areas of stockpiled material; Excavation sites or unsealed roads; Vehicle wash points.

All spoil disposal sites shall be located to ensure that: • • • • • •

The uphill boundary is located as close to the ridgeline as possible to reduce upstream catchment size; Suitable locations for clean-water cut-off drains can be provided; The maximum possible fill volume to surface area ratio is achieved; Any indigenous vegetation clearance is minimised; They are a minimum of 25m from a permanent watercourse; A sediment pond can be located to treat all run-off from the site; and

•

There is all weather vehicle (truck and 4x4 utility vehicle) access to sediment ponds for inspection and maintenance purposes.

The location and details of these spoil sites will be detailed in the SSESCP for that Spoil Site. The SSESCP will also detail how the requirements of Schedule 2 Condition 26 will be met: All spoil disposal sites shall be designed, constructed and managed in accordance with the following: • • • • • • • • • • •

•

The toe bund shall be structural and constructed of weathered rock; The amount of surface area within the spoil site that is exposed at any one time shall be minimised, and limited to a maximum of 3ha per sediment pond; Exposed areas shall be stabilised to the greatest extent practicable at the end of each day, and temporarily covered if possible prior to any significant storm event; A 3% sediment pond (or ponds) (being 3m3 volume for every 100m2 of catchment) shall be constructed to collect and treat run-off from each site; All sediment ponds shall be constructed to provide for retrofitting of flocculation if needed; Flocculation shall be provided for each spoil site sediment pond where: The soils to be placed at the site do not settle to at least 80% removal in 30 minutes and at least 95% removal in 24 hours; and Laboratory testing shows that flocculation can result in at least 80% removal in 30 minutes and at least 95% removal in 24 hours; Compliance with condition 26.6 is to be established by sampling and testing of representative samples of the soils to be placed, both prior to preparation of the SEMP, and during placement in the spoil area; A clean water diversion shall be constructed around each site that is capable of diverting the 1% AEP storm event around the site without erosion; Each spoil site shall be stabilised and grassed over or re-vegetated, as soon as practicable after it has been fully utilised, in order to prevent scour and avoid sediment being washed into adjacent watercourses. Stabilisation may be staged, and stabilised areas diverted to a clean water diversion, to maintain a suitably small working catchment area; and For any spoil disposal sites within the Kahuterawa catchment, stormwater runoff discharged from the sediment pond or external pond batters shall, in addition to any other treatment measures, pass through at least 10m of rank grass buffer before reaching an ephemeral watercourse.

As with dust emissions, the most significant sources of soil/sediment loss are likely to be sediment from unstabilised ground and stockpiles in areas of open earthworks (excavations and embankments). This will be managed through: • • -

Minimising the extent of excavated areas: Limit earthworks extent and vegetation clearance as much as practicable. Stabilise exposed surfaces as soon as practicable and where they will be undisturbed for longer periods. Stabilisation can include metal, paving, polymer, hydroseed, mulch and permanent planting. Minimise the area of surfaces covered with fine materials. Identify any ‘no-go’ areas for vehicles and machinery Ensuring the prescribed erosion and sediment controls are employed: Deploy SEMP controls to all stockpiles that cannot be moved to cleanfill locations Undertake daily checks and regular maintenance of SEMP controls (i.e. clearing and re-instating silt fences or grit traps). Ensure sufficient SEMP controls are in place prior to any forecasted weather event.

Further details of weather event based monitoring, including the location and type of water quality parameter monitoring, is detailed in the Adaptive Aquatic Ecology Management and Response Plan (May 2019). Refer to Annex B for a copy of this report. Further details of erosion and sediment control management is included within the SEMP – refer to Annex I for a copy of this plan. Further details on spoil site locations and their management can be found in the Landscape Plan in Annex H. Document Library Number: DI-PM-TP019

7.3.3-Controlling Soil Contamination and Spills to Water Potential sources of soil contamination on the project include the following: • • •

Hydrocarbons from vehicles or machinery; Pest plant chemical treatments or pesticides. Concrete Product/s and Batching Plant

These risks can be managed through identifying appropriate chemical or fuel storage areas and refuelling points and by complying with the various requirements of Schedule 1, Condition 13 of the consents. The appropriate spill kits, bulk fuel and chemical storage tank bunds or containers will be available on site, with all on--site staff made aware of their location and given clear instructions on usage. No diesel storage tanks will be located within PNCC’s water supply catchment. The following mitigation measures will be implemented to manage hazardous substance use, storage and transport during the project: • • • • • • • • •

Fuel for all construction plant will generally be delivered by mini-tanker and refuelling and lubrication of construction plant will only be carried out in areas separated from environmentally sensitive areas, wetlands, watercourses (including ephemeral watercourses) or overland flow path. Spill kits will be available for use in the event of a spill. Hydraulic oils, greases and other construction materials including small quantities of fuel required for hand tools and pumps may be stored at the site compound, in a secure area. Any hazardous substances kept on site will be stored under cover in accordance with the relevant regulations. Containers of paint, adhesives etc. are not to be left open unless being actively used. Specific concrete and grout wash-down areas shall be provided. Wastes will be disposed of in accordance with appropriate regulations. Spill kits will be maintained at appropriate locations around the site. These site locations will be detailed at all smoko sheds. Major plant maintenance will not be carried out onsite unless absolutely necessary. Minor repairs will be undertaken away from the watercourses or stormwater inlets.

If a hydrocarbon or chemical spill occurs on a grassed or bare ground surface, the affected area will be safely removed and disposed of at an off-site licensed waste disposal facility. Documented evidence will be required from licensed facility and held on site and provided to Client.

Concrete Management: In the event of a significant concrete spill, immediate containment and removal of spilt concrete products from the affected area will commence. As there is little that can be done once the concrete products enter a waterway, the main focus will be on containing the spill to prevent further contamination. Downstream monitoring will then commence to determine the extent of the effects of the spill. To eliminate/minimise the risk of a significant concrete spill/s into waterways, reserves and farmland, the construction of foundation formworks are to meet all statutory building codes of compliance and built as per design. Earth berms may also be implemented to prevent spills into waterways, reserves and farmlands in the event of a catastrophic failure during construction. The Temporary Concrete Batching Plant will also be constructed in an area non-sensitive to risk of spills into major waterways. Berms will also be installed (As applicable) to eliminate risk of spilt concrete into sensitive areas e.g. Native reserve and or farmland. • Specific concrete and grout wash-down areas will also be provided and will incorporate the same controls as above. All spent/redundant concrete/grout wastes will be reused or removed from Project.

Details of the full Emergency responses for managing hazardous substances and any spills is included within the EMPs 7.3.4-Potential loss of bird habitat Indigenous bird species may be affected by the loss of habitat during the construction of the associated infrastructure (e.g. roads and building platforms). However, with construction being confined to ridge top vegetation, effects on mobile bird species are likely to be minimal.

7.3.5-Effect on Bats Mercury’s pre-construction bat monitoring activity recorded no bats at the site. Construction activities will, therefore, be undertaken in accordance with an accidental bat / bat roost discovery procedure to be supplied by Mercury.

7.3.6-Effect on Lizards Mercury’s lizard searching effort has shown that herpetafauna within the Turitea reserve is at very low densities, with only three green gecko (barking gecko) found in horopito scrub vegetation. No other species of skink, gecko or lizard have been found on site. The Department of Conservation is yet to confirm preferred lizard management methodology for this project in light of these lizard search results. Removal of potentially high value lizard habitat may still require some form of pre-clearance lizard search and salvage (e.g. tower locations in the Reserve). In any event, construction activities will be undertaken in accordance with final Lizard Protection Plans.

7.3.7-Effect on Powelliphanta Snail Population Powelliphanta traversi tararuaensis may be present in the area. If found, populations will be translocated to safe sites, which will be carried out in consultation with the Department of Conservation.

7.3.8-Pest Plant Management According to the Wildlands Pest Plant Monitoring and Control Plan for the Turitea Wind Farm (‘Wildlands Report’), it is likely that several environmental and agricultural pest plant species are present within the project site. Likely causes of the spread of pest plant species includes: • •

Lack of on-site knowledge of pest plant identification or management; Pest plant seeds/vegetation unintentionally brought on-site, or transferred throughout the site, from vehicle, machinery/equipment movements and people.

The Wildlands Report recommends nominating a person on-site to manage any current or future pest plant issues. They will be responsible for developing skills in identifying common agricultural and environmental pest plans and must know how to access services necessary for the identification of suspect plants. A visual inspection for pest plants should be conducted during the daily Health and Safety, Risks and Hazards check of the site, and the nominated person must know how to respond to the presence of particular pest plants. With regards to vehicle, machinery or equipment hygiene, the Wildlands Report has recommended that an onsite Clean-down area be created to remove any vegetation or debris prior to commencing clean-down at the end of each job or when moving onto the site. Clean-down procedures include washing, blowing, vacuuming, sweeping, steam-clearing and dislodging unwanted material from equipment, machinery and personnel. The Site Manager will be responsible for ensuring that vehicles, machines, or items of equipment are cleaned thoroughly. Contractors must follow this general clean down procedure to a high standard, as appropriate, at the end of each job and before moving to a new location. A log should be kept of what was cleaned, when and if any unwanted organisms found, what were they and what was done with them.

To educate all staff on site, photographic examples of all relevant plant pests will be displayed in the site office. All staff will be instructed to look out for and remove such plants from the site or their machinery once identified. Such plants shall be placed in the designated “Pest Plant Bin” for appropriate disposal. Staff will be encouraged to contribute to the records in the Pest Plant Plan. Further details of the prescribed level of on-site education and procedures to follow for a Clean-down area can be found in Annex C, Wildlands Pest Plant Monitoring and Control Plan for the Turitea Wind Farm.

7.4

Emergency responses for managing environmental hazards

Prompt and effective emergency preparedness and response reduces losses and the consequences of natural and anthropogenic causes. Project Managers are to ensure that Emergency Plans (e.g. as per section 4.2 of the DN-ZH-PR015 Emergency Preparedness procedure) are in place to cover the range of emergency events that may be expected at that location and that set out: • • •

who is responsible in an emergency situation (e.g. Building Warden, see Section 2.1), what scenarios are expected, and the associated response.

Trials of other emergency response plans (e.g. civil defence or chemical spill) should also be undertaken at least every 6 to 9 months. Should an incident occur, a full investigation is to be carried out in accordance with corporate procedures. 7.4.1-Schedule specific scenarios As required by condition 6.11 of Schedule 1, details on our proposed contingency plan in relation to specific environmental emergencies are as follows: Scenario a) Riparian zone restoration and de-silting of the Palmerston North City Council water supply reservoirs in the event of significant erosion / washout events occurring during and caused by construction of the wind farm •

Riparian zone restoration: Once the site is safe to examine, an investigation to identify the cause and extent of the damage to the riparian zone would be undertaken, as well as identifying what erosion and sediment controls would need to be deployed to stabilise the site. A full report of this investigation would then be promptly be submitted to the respective Head Contractor and Council’s Environmental Manager/s for assessment. Once the site has been stabilised using erosion and sediment controls identified in the SEMP, the site would then be monitored and maintained until it was appropriate to undertake replanting activities. When able, the site will then be replanted in accordance with the Wildlands Rehabilitation and Revegetation Plan and Landscape Plan for the Turitea Wind Farm. A copy of these plans can be found in Annex G and Annex H respectively.

•

De-silting of the PNCC water supply reservoirs Should such an event occur, once the work site was stabilised using erosion and sediment controls identified in the SEMP, an immediate investigation into the incident would then commence to identify the cause and to understand the severity of contamination. Subject to the volume of sediment and the magnitude of the incident, options such as pumping contaminated water from the reservoir could be utilised, or in the case of a catastrophic failure an excavator or dredge could be deployed to remove built up sediment.

All remedial options will first be discussed with the Client and relevant Councils Environmental Managers for approval prior to conducting the activity. Scenario b) Early notification of downstream users and monitoring of a clean-up response in the event of significant spillage of hydrocarbons / concrete products to watercourses occurring during construction of the wind farm Notice of either incident, including details of the clean-up response, will be given to Mercury who will then contact Horizonâ&#x20AC;&#x2122;s Regional Council via the pollution hotline (24hr freephone: (+64) 0508 800 800) and in the first instance notify any owners of downstream water takes potentially affected. Regarding, on the ground response, in the event of a significant hydrocarbon spill, once the source has been contained, a team will deploy appropriately sized booms at the downstream most extent of the spill as soon as practicable.

The team will also be responsible for removing as much of the hydrocarbon spill as possible from the stream and surrounding vegetation through the use of absorbent pads or rolls or other practical means to stop spill flowing to waterways. To eliminate/minimise the risk of a significant hydrocarbon spill, all Bulk storage of Hydrocarbons and chemicals will be in certified and compliance registered bunds or tanks and not stored in PNCC water supply catchment or where in event of catastrophic failure can enter any water ways. Refuelling and servicing of equipment will not be undertaken where there is a risk of spills into waterways. Refer to EMP for safe storage and handling of Hydrocarbons and Chemicals onsite. In the event of a significant concrete spill, immediate containment and removal of spilt concrete products from the affected area will commence. As there is little that can be done once the concrete products enter a waterway, the main focus will be on containing the spill to prevent further contamination. Downstream monitoring will then commence to determine the extent of the effects of the spill.
