1 Annex L Project Risk Analysis Matrix

2 L1 Table L1 Project Environmental Risk Analysis Local Road upgrades: Loss/damage cultural heritage values Low Acceptable Loss/damage of biodiversity value, EEC Construction Traffic and Access Introduction/spreading weeds Deterioration of air quality (e.g. dust) Impacts visual amenity. Stakeholder and Community Engagement Road safety Requirements of road Traffic disruption authority. Site establishment: site offices installation laydown and parking areas power supply vehicle movements transport people and from site transport equipment and materials site office Traffic disruption/accidents Clearing of native vegetation (EEC) Introduction of weeds Damage stakeholder relationships Contaminated soil Deterioration of air quality (e.g. dust) Impacts visual amenity Low Acceptable Construction Traffic and Access Stakeholder and Community Engagement Construction Compound and Ancillary Facilities

3 L2 Earthworks for access tracks transport gravel, form roads, create drainage apply road surfacing Low Acceptable Earthworks for wind turbine footings and hardstands: excavation (cut/fill) transport gravel, form hardstand, stabilise batters create drainage apply surfacing form sckpiles Loss or damage of cultural heritage values Loss/damage of biodiversity value Introduction/spreading weeds Deterioration of air quality (e.g. dust) Impacts visual amenity. Loss/damage cultural heritage values Loss/damage of biodiversity value, EEC Spreading weeds Deterioration of air quality Impacts visual amenity Low Acceptable Construction Noise and Vibration Construction Soil and Water Quality Construction Heritage Construction Noise and Vibration Construction Soil and Water Quality Construction Heritage

4 L3 Earthworks for substation: Loss/damage cultural heritage values Low Acceptable Loss/damage of biodiversity value excavation (cut/fill) Construction Noise and transport gravel, Vibration form hardstand, Construction Soil and Water stabilise batters Spreading weeds Quality create drainage Construction Heritage apply surfacing Deterioration of air quality form sckpiles Impacts visual amenity Concrete Batch t: earth works for bench transport gravel, sand, water site install site drainage operate batch plant, load and dispatch agitar trucks Traffic generation and accidents Damage local roads Air quality (dust) Pollution of waters Introduction/spread of weeds Low Acceptable Decision on siting of t Compound and Ancillary Facilities Heritage

5 L4 Trenching: Clearing cable route Excavate trench Install sand and cables Backfill Low Acceptable Resre surface and revegetate Install overhead line: provide temporary access clearing pole sites and hardstands form hardstands install poles string conducrs tension resre disturbance Loss of biodiversity value Soil disturbance and changes hydraulic regime Loss of cultural heritage Impacts visual amenity Introduce / spread weeds Deterioration of air quality (dust) Loss of biodiversity value Soil disturbance and changes hydraulic regime Loss of cultural heritage Introduce / spread weeds Deterioration of air quality (dust) Impacts visual amenity Low Acceptable Compound and Ancillary Facilities Communication Heritage Heritage

6 L5 Temporary sckpiles Loss of biodiversity Low Acceptable Establishment of erosions and sediment controls; and changes Construction Compound and Use of earth moving hydraulic regime Ancillary Facilities equipment; Introduce / spread weeds Clearing and sckpiling Deterioration of air quality (dust) Air Quality Management of vegetation and psoil; Impacts visual amenity Importation of sckpile material;. Re-use of sckpile material; and Rehabilitation of disturbed areas. Heritage Transport large components site: transport large items site use crane unload at temporary site or hardstand adjacent footing transport truck leaves site Damage roads / bridges and street furniture Traffic disruption and road safety Impact on water quality Low Acceptable ; ; Stakeholder and Community Engagement

7 L6 Wind turbine assembly and Disturbance outside standard hours Low Acceptable Stakeholder and Community erection: Engagement layout components Deterioration of air quality bring crane site and Impact on water quality and changes assemble hydraulic regime operate crane with crew + OOHW erect components secure each section remove crane from site
