Appendix I: Environments, Hazards and Climate Changes

Environment Natural Hazards and Climate Change Arid/Semi-arid and desert environments

Low erratic rainfall of up to 500 mm rainfall per annum with periodic droughts and high rainfall variability. Low vegetative cover. Resilient ecosystems & complex pastoral and systems, but medium certainty that 10–20% of dry lands degraded; 10-30% projected decrease in water availability in next 40 years; projected increase in drought duration and severity under climate change. Increased mobilization of sand dunes and other soils as vegetation cover declines; likely overall decrease in agricultural productivity, with rain-fed agriculture yield reduced by 30% or more by 2020. Earthquakes and other geophysical hazards may also occur in these environments.

Humid and sub-humid plains, foothills and hill country

More than 500 mm precipitation/yr. Resilient ecosystems & complex human pastoral and cropping systems. 10-30% projected decrease in water availability in next 40 years; projected increase in droughts, heat waves and floods; increased erosion of loess-mantled landscapes by wind and water; increased gully erosion; landslides likely on steeper slopes. Likely overall decrease in agricultural productivity & compromised food production from variability, with rain-fed agriculture yield reduced by 30% or more by 2020. Increased incidence of forest and agriculture-based insect infestations. Earthquakes and other geophysical hazards may also occur in these environments.

River valleys/ deltas and estuaries and other low-lying coastal areas

River basins, deltas and estuaries in low-lying areas are vulnerable to riverine floods, storm surges associated with tropical cyclones/typhoons and sea level rise; natural (and human-induced) subsidence resulting from sediment compaction and ground water extraction; liquefaction of soft sediments as result of earthquake ground shaking. Tsunami possible/likely on some coasts. Lowland agri-business and subsistence farming in these

Small islands

Small islands generally have land areas of less than 10,000km2 in area, though Papua New Guinea and Timor with much larger land areas are commonly included in lists of small island developing states. Low-lying islands are especially vulnerable to storm surge, tsunami and sea-level rise and, frequently, coastal erosion, with coral reefs threatened by ocean warming in some areas. Sea level rise is likely to threaten the limited ground water resources. High islands often experience high rainfall intensities, frequent landslides and tectonic environments in which landslides and earthquakes are not uncommon with (occasional) volcanic eruptions. Small islands may have low adaptive capacity and high adaptation costs relative to GDP.

Mountain ecosystems

Accelerated glacial melting, rock falls/landslides and glacial lake outburst floods, leading to increased debris flows, river bank erosion and floods and more extensive outwash plains and, possibly, more frequent wind erosion in intermountain valleys. Enhanced snow melt and fluctuating stream flows may produce seasonal floods and droughts. Melting of permafrost in some environments. Faunal and floral species migration. Earthquakes, landslides and other geophysical hazards may also occur in these

Volcanic environments

Recently active volcanoes (erupted in last 10,000 years – see www.volcano.si.edu). Often fertile soils with intensive agriculture and landslides on steep slopes. Subject to earthquakes and volcanic eruptions including pyroclastic flows and mudflows/lahars and/or gas emissions and occasionally widespread ash fall.

The control room building is designed by taking the seismicity of area under consideration. The selected substation site is at a high lying area and is not present in flood prone area. However distribution line may be located in such area and design of pole will be done by taking it into consideration.

Would the project design (e.g. the clearance for bridges) need to consider any hydro-meteorological parameters (e.g., sea-level, peak river flow, reliable water level, peak wind speed etc)?

0

Materials and Maintenance

Would weather, current and likely future climate conditions (e.g. prevailing humidity level, temperature contrast between hot summer days and cold winter days, exposure to wind and humidity hydro-meteorological parameters likely affect the selection of project inputs over the life of project outputs (e.g. construction material)?

0

Would weather, current and likely future climate conditions, and related extreme events likely affect the maintenance (scheduling and cost) of project output(s)?

0

Performance of project outputs

Would weather/climate conditions and related extreme events likely affect the performance (e.g. annual power production) of project output(s) (e.g. hydro-power generation facilities) throughout their design life time?

0

Options for answers and corresponding score are provided below:

Screening Questions Yes No Remarks Risks and vulnerabilities related to occupational health

and safety due to physical, chemical, biological, and radiological hazards during project construction and operation? √


Chemical pollution resulting from chemical clearing of vegetation for construction site? √ Not involved


√

Blasting is not involved in construction of substation. Hence no such impact is anticipated. However, during construction phase noise level may increase due to operation of machinery.

Dislocation or involuntary resettlement of people? √ Not involved Disproportionate impacts on the poor, women and

children, Indigenous Peoples or other vulnerable groups?

√ No such impact is involved.

Social conflicts relating to inconveniences in living conditions where construction interferes with pre-existing roads?

√ No such conflict is anticipated.

Hazardous driving conditions where construction interferes with pre-existing roads? √ No such condition is anticipated.

Creation of temporary breeding habitats for vectors of disease such as mosquitoes and rodents? √

This impact is anticipated during construction stage, but necessary facilities such as proper disposal of waste water, and sanitation system etc. shall be ensured at labour camp.

Dislocation and compulsory resettlement of people living in right-of-way of the power transmission lines?

√

No such impact is anticipated, since alignment of associated are 33kV and 11kV lines are generally proposed within RoW of existing road and in some cases through agriculture field.

Environmental disturbances associated with the maintenance of lines (e.g. routine control of vegetative height under the lines)?

√

The route survey of associated lines is still to be carried out. The routine control of vegetation height may be involved and will be taken care once the route alignment is finalized.

Facilitation of access to protected areas in case corridors traverse protected areas?

√

The route survey of associated lines is still to be carried out. The alignment of 33kV and 11kV is likely to be proposed within the existing RoW alongside road. Design measures needs to be taken as the lines might transverse from protected area.

Disturbances (e.g. noise and chemical pollutants) if herbicides are used to control vegetative height?

√

Physical method such as cutting, pruning, and trimming would be adopted during routine maintenance.

Large population influx during project construction and operation that cause increased burden on social infrastructure and services (such as water supply and sanitation systems)?

√ Labour requirement is about ten (approx.) and employment of local labour will be first priority. Hence, no such impact is anticipated.

Social conflicts if workers from other regions or countries are hired?

√

Priority shall be given to locally available labour. Hence, would aid in minimizing social conflict.

Poor sanitation and solid waste disposal in construction camps and work sites, and possible transmission of communicable diseases from workers to local populations?

√

Providing of suitable sanitation facilities for workers at labor camp will be ensured through regular monitoring of contractor’s operation during construction stage.

Risks to community safety associated with maintenance of lines and related facilities?

√

No such impact is anticipated. However, advance notice shall be provided before maintenance activity.

425

Screening Questions Yes No Remarks Community health hazards due to electromagnetic

fields, land subsidence, lowered groundwater table, and salinization?

√ Safe vertical distance required for distribution shall be maintained as per regulatory requirement. Hence, no such impact is anticipated.

Risks to community health and safety due to the transport, storage, and use and/or disposal of materials such as explosives, fuel and other chemicals during construction and operation?

√ No such impact is anticipated. The transformer oil will be transferred to substation is sealed drums with proper storage area.

Community safety risks due to both accidental and natural hazards, especially where the structural elements or components of the project (e.g., high voltage wires, and transmission towers and lines) are accessible to members of the affected community or where their failure could result in injury to the community throughout project construction, operation and decommissioning?

√

School and house are present nearby the project site. Thus, additional safety measures. Appropriate safety sign boards and boundary wall needs to be maintained properly. Awareness program requires to be carried out regarding the electrical safety measures for nearby residents.

A Checklist for Preliminary Climate Risk Screening

Country/Project Title: Assam Power sector enhancement Investment program, Tranche 4 (IND-3200) Sector: Buildings Subsector: Power Substation (33/11kV Kaliapani substation) Division/Department:Duliajan Division/APDCL

Screening Questions Score Remarks61 Location and Design of project

Is siting and/or routing of the project (or its components) likely to be affected by climate conditions including extreme weather related events such as floods, droughts, storms, landslides? 0

The control room building is designed by taking the seismicity of area under consideration. The selected substation site is at a high lying area and is not present in flood prone area. However distribution line may be located in such area and design of pole will be done by taking it into consideration.

Would the project design (e.g. the clearance for bridges) need to consider any hydro-meteorological parameters (e.g., sea-level, peak river flow, reliable water level, peak wind speed etc)?

0

Materials and Maintenance

Would weather, current and likely future climate conditions (e.g. prevailing humidity level, temperature contrast between hot summer days and cold winter days, exposure to wind and humidity hydro-meteorological parameters likely affect the selection of project inputs over the life of project outputs (e.g. construction material)?

0

Would weather, current and likely future climate conditions, and related extreme events likely affect the maintenance (scheduling and cost) of project output(s)?

0

Performance of project outputs

Would weather/climate conditions and related extreme events likely affect the performance (e.g. annual power production) of project output(s) (e.g. hydro-power generation facilities) throughout their design life time?

0

Options for answers and corresponding score are provided below:
