This EIA report has thus been prepared by the Ministry of Environment and Communications with technical assistance from the JICA Preparatory Survey. The requirements stipulated in the Environmental Impact Assessment Regulations, 2010, and JICA’s “Guidelines for Environmental and Social Considerations (2010)” were referred in the process.
Following the assessment of the environmental and social economic impacts, as well as the potential impacts to the social uses of site, it has been determined that the proposed site for the project appears to be suitable for the development. This determination takes into account the environment, construction feasibility and economic values of the proposed development.

DEFINITION : Trend in consumption of ozone depleting substances (ODS)
PURPOSE : Tracks countries progress to phasing out ODS. Ozone depleting substances destroy the earth’s ozone which protects the earth from UV radiation
DESIRED OUTCOME : Negative trend in ODS consumption
DEFINITION : Trend in percentage production of energy from renewable sources
PURPOSE : Energy generation is a major source of GHG emissions. Pacific island countries also have limited capacity for oil and gas storage and are therefore highly vulnerable to fluctuations in fossil fuel price and availability
DESIRED OUTCOME : Positive trend in energy production from renewable sources
DEFINITION : Annual per capita generation of municipal solid waste
PURPOSE : Accurate measurement of per capita waste generation for better waste management
DESIRED OUTCOME : Stabilisation and subsequent negative trend in household waste generated
DEFINITION : Quantity of generated hazardous wastes processed/treated (including export)
PURPOSE : Treatment and safe storage of hazardous waste mitigates the risk to humans and nature. Hazardous materials can have direct and indirect, chronic or acute impacts
DESIRED OUTCOME : Full treatment/processing of all hazardous waste generated
DEFINITION : % of households connected to central sewerage system
PURPOSE : Tracks progress in managing sewage in a way that minimises the risk of water contamination. Untreated sewage and leaking septic systems are a major source of ground and surface water contamination
DESIRED OUTCOME : Positive trend in % of households connected to central sewerage system
