3) The Detailed EIA is not a comprehensive document, but rather focuses on the issues of primary concern. It should be undertaken in close liaison with engineering, financial and other project planners. The Detailed EIA is subject to a similar review process as the preliminary EIA 30 . Public consultation is regarded as being a very important part of the EIA process. The project proponents are expected to ensure that public consultation does take place during the EIA. The general public must also have access to all documentation on the project written during the EIA process 31 . The Interim EIA Policy is backed by a draft "General Environmental Impact Assessment Guidelines". This detailed document covers the general format that should be used when preparing an EIA. Again, public consultation is considered to be a vital part of the process. The proponents are also required to draw up an environmental management plan. It should be noted that the Ministry is in the process of drawing up the Environmental Management Act, which seeks to combine the disjointed legislation controlling use and abuse of the environment into a single Act.
