The environmental impact assessment (EIA) procedure needs to be overhauled so that controversial projects can be reviewed more thoroughly and political responsibility is more clearly defined, environmentalists said yesterday.

The Environmental Protection Administration (EPA) today will hold its fifth EIA meeting related to a controversial petrochemical project planned by Kuokuang Petrochemical Technology Co for a wetlands area in Changhua County.

Environmental activists have criticized the EIA process, calling its as flawed.
