Recommendations of the EAP - CESNET WEF Draft Scoping...Environmental Affairs North Region Dr LW...

EOH Coastal & Environmental Services Waaihoek Wind Energy Facility 124

• Increases in the demand for electricity as the South African economy grows will increase the amount of fossil fuels required to generate this electricity.

11.5 Opinion of the EAP The proposed Waaihoek WEF is consistent with South African and KwaZulu-Natal renewable energy and climate change policies. Although a number of significant impacts are associated with the project, it is the professional opinion of CES and the specialists that: • The vast majority of environmental impacts identified can be adequately mitigated to reduce

the impacts to an acceptable level, provided mitigation measures recommended in this report are implemented and maintained throughout the life of the project.

• The implementation of mitigation measures and recommendations must be consistently monitored by an independent Environmental Control Officer (ECO) during construction.

• In particular, the implementation of measures suggested by the Bat specialist to mitigate the effect of the WEF, during both construction and operation, is particularly important.

• The recommendations made by all specialists and the EAP in the EMPr (Appendix F, Section 14.6) must be implemented

• The information in the report is sufficient to allow DEA to make an informed decision. It is the opinion of Coastal & Environmental Services (CES) that NO FATAL FLAWS are associated with the proposed Waaihoek WEF and associated infrastructure (including powerline).

11.6 Recommendations of the EAP It is the opinion of CES that the proposed development should be approved provided that appropriate mitigation measures are implemented and that the Environmental Management Programme (EMPr) is implemented, maintained and adapted to incorporate relevant legislation, standard requirements and audit reporting, throughout the life of the development. The mitigation measures for all impacts identified in the EIA are provided in the detailed assessment in Appendix D and have been incorporated into the EMPr. The EMPr must be implemented by the relevant parties during all phases of the WEF development of the project, viz. Planning & Design, Construction, Operational and Decommissioning phase. Inclusions, additions and adaptations of the EMPr, as well as all final plan drawings and maps must be submitted to DEA (Pretoria) for final approval.

This information is considered, by the developer, to be confidential because of its commercial sensitivity. The preferred site was chosen based on an in-house study on the wind resource in the broader area. The findings of this study were supported by historic data from a local weather station. Together this research provided a comprehensive macro wind model of the area, which clearly illustrated the preferred site as an optimal site for a wind farm. A met mast which was subsequently installed on site has confirmed the expected wind resource. In addition to the wind resource, other key factors which indicated that the site is potentially suitable for a wind farm included but were not limited to proximity to and availability of Eskom grid, site access and constructability, and potential environmental and social sensitivities.

PLANNING & DESIGN PHASE

GENERAL IMPACTS

Traffic & Transport

Inadequate planning for the transportation of turbine parts and specialist construction equipment to the site by long and/or slow moving vehicles could cause traffic congestion, especially if temporary road closures are required.

DIRECT Regional Short-term Possible Moderately Severe MODERATE • Project planning must include a plan for traffic control that will be implemented, especially during the construction phase of the development. Consultation with the local Road Traffic Unit in this regard should be done early in the planning phase. The necessary road traffic permits should be obtained for transporting parts, containers, materials and construction equipment to the site.

LOW

The integrity of existing highway infrastructure such as bridges and barriers may be compromised by the heavy vehicle traffic delivering components to the site.

DIRECT CUMULATIVE

Regional Short-term Possible Slight LOW • Careful planning of the routes taken by heavy vehicles must highlight areas of road that may need to be upgraded in order to accommodate these vehicles. Once identified, these areas must be upgraded if necessary.

LOW

Inappropriate planning for road construction can increase the risk of surface water run-off, loss of biodiversity, soil erosion, etc.

DIRECT CUMULATIVE

Localised Medium-term Possible Severe HIGH • It is recommended that strip access roads should be used to maintain ecosystem integrity as much as possible. Strip roads should not be tarred. Limit the number of strip roads on site to minimise their overall footprint.

LOW

Road modifications which may be necessary to allow for the delivery of components to site via heavy vehicles could have long lasting traffic benefits.

INDIRECT CUMULATIVE

Regional Long-term Probable Slightly beneficial LOW POSITIVE

• If roads are upgraded, this should improve the conditions for all users of the roads.

LOW POSITIVE

Storage of hazardous substances

Inappropriate planning for the storage of hazardous substances such as diesel, paint, pesticides, etc, tools and equipment used on site could lead to surface and ground water pollution e.g. due to oil leaks, spillage of diesel etc. In addition, these hazardous substances could be washed off into nearby drainage lines. The mixing of cement on site could result in ground water contamination from compounds in the cement. In addition, a large number of cement mixing stations on site could increase the presence of impermeable areas of hard standing which in turn could increase rates of run-off and thereby increasing the risk of localized flooding, soil erosion, silting, gullies, etc.

DIRECT CUMULATIVE

Localised/ Nearby river and

water systems

Short-term Possible Moderate MODERATE • All hazardous substances such as paints, diesel and cement must be stored in a bunded area with an impermeable surface beneath them.

• Cement mixing must be conducted at a single location which should be centrally located, where practical.

LOW

Environmental Legal and Policy

Compliance

Failure to adhere to existing policies and legal obligations could lead to the project conflicting with local, provincial and national policies, legislation etc. This could result in lack of institutional support for the project, overall project failure and undue disturbance to the natural

DIRECT CUMULATIVE

Municipal Long-term Possible Severe HIGH • Ensure that all relevant legislation and policy is consulted and further ensure that the project is compliant with such legislation and policy.

• These should include (but not restricted to): o Local and District Spatial Development

Frameworks

LOW


environment. o KwaZulu-Natal Biodiversity Conservation Plan

o Local Municipal bylaws • In addition, planning for the construction and

operation of the proposed energy facility should consider available best practice guidelines.

Stormwater Management and Erosion

The introduction of roads and impermeable areas of hard standing could increase rates of run-off and therefore the risk of localised flooding.

INDIRECT Localised/ Nearby river and

water systems

Long-term Possible Severe HIGH • Structures must be located at least 32 m away from identified drainage lines.

• A Stormwater Management Plan must be designed and implemented to ensure maximum water seepage at the source of water flow.

• The plan must also include management mitigation measures for water pollution, waste water management and the management of surface erosion e.g. by considering the applicability of contouring, etc.

LOW

Inappropriate storm water management will lead to damage, pollution and potential flooding of the site.

DIRECT Study Area Medium-term Possible Severe HIGH • A stormwater management plan must be developed and implemented

LOW

Management of general waste

Inappropriate planning for management and disposal of waste e.g. storage disposal could result in surface and ground water contamination.

DIRECT INDIRECT

CUMULATIVE

Localised Long-term Possible Severe HIGH • Develop and implement a waste management plan for handling on site waste.

• Designate an appropriate area where waste can be stored before disposal.

LOW

Electromagnetic Interference

(EMI)

WEFs can cause television, radio and microwave interference by blocking and / or causing part of the signal to be delayed.

DIRECT Regional Long-term Probable Moderately Severe MODERATE • Accurate siting of wind turbines in the planning and design phase should reduce these effects.

• If complaints are received from surrounding landowners regarding this issue, the developer must investigate and mitigate these issues to the best of their abilities.

LOW

Vegetation Clearing

Risk of designing long and wide access roads that would require wide scale vegetation stripping on site thereby compromising local biodiversity.

DIRECT CUMULATIVE

Localised Long-term Possible Severe HIGH • It is recommended that internal roads should comprise of strip roads to maintain ecosystem integrity as much as possible.

• Strip roads should not be tarred.

LOW

Risk that digging the trenches for an underground connecting cables could adversely affect surface vegetation and damage soil structure.

DIRECT Study Area Medium-term Probable Severe HIGH • Route determination for the underground connecting cables should consider the shortest possible routes.

• The size of the underground trenches for the connecting cables must be limited to the minimum acceptable dimensions appropriate for laying down the cables.

MODERATE

Landscape and Visual

Design and siting of the wind turbines could result in an alteration of the landscape character and sense of place
