Part III : How to Conduct SEA?
A Generic SEA Process - An Iterative Process
Generic Steps of SEA
(click any box for details)
Continuous and earliest possible interaction with stakeholders and the public Understanding the needs, nature & objectives of PPPs
Design/select SEA process & methods
Initial screening & scoping
Base line/background studies
Identify & examine strategic environmental issues & linkages
Identify & evaluate possible options, alternative means & resulting environmental implications
Identify & evaluate preferred options
Determine follow-up actions, monitoring requirements
 
Step 7 : Identification and Evaluation of Preferred Options

With refined development options selected in Step 6, their net residual environmental implications upon implementation of mitigation measures should be identified and evaluated. The extent of uncertainties on the prediction of environmental implications and major assumptions due to such factors as long time frame should be stated.

Preferred option(s) should then be determined with their major pros and cons highlighted. If options with the best environmental performance are not selected, justifications or rationale behind the recommendation should be singled out and stated clearly for proper deliberation by concerned stakeholders.

+ Example – Extension of Existing Landfills and Identification of Potential New Waste Disposal Sites

Following Step 6, environmental assessments of 15 short-listed sites were carried out in which their net environmental implications were thoroughly discussed and compared. For example, a comprehensive water quality assessment was conducted on the basis of potential sediment contaminant releases; watercourse diversions required, potential impacts on water sensitive receivers; hydrodynamic changes due to reclamations; potential impacts on groundwater and cumulative water quality impacts etc.

The process ultimately identified 5 suitable sites in Hong Kong for further detailed feasibility study with key environmental implications, potential problems, the pros and cons of different options transparently presented to the stakeholders.
