Coega Integrated LNG-to-Power Project EIA
List of Information Requirements for specialist studies
Collated by: Emma Gordge and Paul Lochner, CSIR
Version 1 (10 August 2006)
PURPOSE OF THIS DOCUMENT:
This document is to be used by Eskom, iGas and their consultants, as well as members of the CSIR EIA team, to: (i) check key assumptions;
and (ii) source relevant information required for the specialist studies for the EIA. Note that separate documents with information requirements
are provided for the marine discharges and macro-economics specialist studies, due to the very specific inputs for these studies.
Information inputs are requested to be provided via Eskom to the CSIR Project Leader (Paul Lochner) by 25 August 2006. If all information is
not available by that date, please provide as much as is available, and follow up with outstanding information as soon as possible thereafter.
