Indica<strong>to</strong>r Score Comment<br />
Water: Water quantity: This indica<strong>to</strong>r is used <strong>to</strong><br />
evaluate the project’s contribution <strong>to</strong> water<br />
availability and access locally and regionally.<br />
Number of people with access <strong>to</strong> water supply in<br />
comparison with the baseline.<br />
Water quality: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />
the contribution of the project <strong>to</strong> water quality<br />
locally and regionally in the project’s area in<br />
comparison with the baseline. Water quality will be<br />
measured using concentration of main pollutants<br />
(including BOD and others) in any effluents<br />
generated by the project activity and their<br />
contribution, if any, <strong>to</strong> local water quality.<br />
Dependent on the result of the EIA, both quantity<br />
and quality assessment should discuss seasonal<br />
variation of availability and quality in addition <strong>to</strong><br />
mean annual data due <strong>to</strong> the fact that mean<br />
annual data might not be sufficient <strong>to</strong> provide full<br />
understanding of impacts of the project activity<br />
against the baseline.<br />
Air quality: This indica<strong>to</strong>r is used <strong>to</strong> evaluate the<br />
contribution of the project <strong>to</strong> local air quality. Air<br />
quality will be measured by comparing the<br />
concentration of most relevant air pollutants (e.g.:<br />
SOx, NOx, particulate matters etc.) generated by<br />
the project activity with the baseline.<br />
Other pollutants: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />
the contribution of the project activity <strong>to</strong> reducing<br />
the flow of pollutants not already considered <strong>to</strong> the<br />
environment, including solid, liquid and gaseous<br />
wastes.<br />
Soil condition: This indica<strong>to</strong>r is used <strong>to</strong> evaluate<br />
the contribution of the project activity <strong>to</strong> local soil<br />
condition. Soil condition will be measured by<br />

1 The water quality is affected in a positive<br />
way. Wood chips that are used for firing of<br />
the boilers originate from the processing of<br />
sawdust that currently accumulates on large<br />
heaps. According <strong>to</strong> local fishermen,<br />
effluent of these heaps through leaching<br />
has an adverse impact on the water quality.<br />
This can be considered a minor positive<br />
impact.<br />
0 Several studies 8 . show that the Project<br />
Activity (biomass burning) emits similar if<br />
not less amounts of relevant air pollutants<br />
(e.g.: SOx, NOx, particulate matters etc.)<br />
than the baseline (coal burning). An<br />
indica<strong>to</strong>r of 0 is therefore conservative.<br />
1 At present the ash from the boilers at<br />
<strong>Letaba</strong> is landfilled on the property. In the<br />
Project Activity less waste will be produced<br />
(because the coal has a 14% ash content<br />
and the biomass only 3%) and it will be<br />
landfilled as before. If all peels are dried<br />
and none are landfilled, methane formation<br />
will be further avoided on the <strong>Letaba</strong> landfill<br />
(no VERs will be claimed for this).<br />
0 Soil erosion and land use changes are not<br />
impacted, since the biomass in the form of<br />
Eucalyptus and Pine sawdust is renewable<br />
