NWPCP is environmentally a highly sensitive project in the MWSIP. Since there is a sanctuary and forest reserves in the project area, the Project has attracted keen attention to various aspects of environmental safeguards.

MWSIP has been making extensive efforts to ensure the environment will be safeguarded while the project is being implemented. An Environmental Management Plan (EMP) has been prepared and has obtained the approval of the Central Environment Authority, Wayamba Environment Authority and ADB. MWSIP has also obtained the consent of the Forest Department and Department of Wildlife for the implementation of the project.

An “Environment Safeguard Unit” has been formed in the MWSIP for tracking the implementation activities according the EMP following the commencement of project construction activities.

Some studies are currently still on going to find possible options to address the human-elephant conflict in the project areas.  Reforestation programs are scheduled to recover the forest coverage in the affected areas.  Project Affected Persons (PAPs) can lodge any grievances regarding environmental issues related to the project. Grievances Redress Committees (GRCs) have been formed in the project area to hear any relevant complaints.
