The document discusses environmental impact assessments (EIAs) for development projects. The goals of an EIA are to 1) examine project options and select the best, 2) identify mitigation measures, 3) predict residual impacts, 4) determine significant residual impacts, and 5) identify environmental costs and benefits. EIAs are required by law in Malaysia to prevent environmental problems from projects. Parameters addressed in EIAs include impacts to the physical/natural environment like soil/water/flora/fauna, and human/social impacts like noise/air/land use/heritage. Examples demonstrate assessing hydrological changes and using noise barriers for mitigation.

2. What is Environmental Impact
Assessment?
http://www.jas.sains.my/doe/egeia.htm
The aim of the environmental impact assessment is to
assess the overall impact on the environment of
development projects proposed by the public and private
sectors. The objectives of environmental impact
assessment are:
1. To examine and select the best from the project options
available;
2. To identify and incorporate into the project plan
appropriate abatement and mitigating measures;
3. To predict significant residual environmental impacts;
4. To determine the significant residual environmental
impacts predicted; and
5. To identify the environmental costs and benefits of the
project to the community.
3. Why do we need EIA?
EIA is essentially a planning tool for
preventing environmental problems due to
an action. It seeks to avoid costly mistakes
in project implementation, either because of
the environmental damages that are likely
to arise during project implementation, or
because of modifications that may be
required subsequently in order to make the
action environmentally acceptable. In
Malaysia, EIA is required under section 34A,
Environmental Quality Act, 1974.
