Since the early 1990s the Secretariat of the Pacific Regional Environment Programme (SPREP) has been promoting the use of environmental planning and assessment processes amongst its member countries and territories. SPREP's approach to environmental planning and assessment has been part of a global programme for improving environmental management and supporting sustainable development.
The Government of Samoa under its Environmental Policy Framework established rules and procedures to be followed under IAMP Phase 2 with regard to environmental assessment, monitoring and mitigation of potential negative impacts. For projects with no, or low but acceptable environmental impacts, the Chief Executive Officer (CEO), Ministry of Natural Resources and Environment (MNRE) may issue a waiver to the proponent from the further requirements of the draft EIA Regulations. In issuing a waiver, the CEO MNRE will rely on the advice of the Assistant CEO, PUMA.
