Environmental Assessment<br />
2002 Review and Update<br />
7 SUMMARY OF SIGNIFICANT ENVIRONMENTAL EFFECTS AND<br />
MITIGATION MEASURES<br />
The identification and assessment of environmental hazards and effects in the asset<br />
are discussed in Chapter 6. All adverse environmental effects with medium to extreme<br />
risk are considered as significant environmental effects. In this chapter, the additional<br />
mitigation measures required for minimizing the environmental consequences from<br />
these effects are developed. It may be noted that <strong>PDO</strong> has a comprehensive<br />
environmental management plan as a part of the HSE management system (refer<br />
Chapter 2), which is implemented in the asset. No change in the existing<br />
environmental management system is required. However, certain additional<br />
mitigation measures will reduce the potential environmental risk and improve the<br />
overall environmental performance.<br />
The significant environmental effects are listed below along with explanatory notes.<br />

Comments<br />
• MAF STP effluent quality<br />
exceeded the permissible limits.<br />
• The potential risk is<br />
predominantly due to long term<br />
discharge of large amount of<br />
treated sewage on land areas that<br />
are accessible to public.<br />
• STP monitoring is not<br />
comprehensive and some critical<br />
parameters such as heavy metals,<br />
phenols, sodium absorption ratios<br />
etc. are not monitored.<br />
• While the ambient air quality in<br />
the areas serviced estate services<br />
is least affected by air emissions<br />
from estate services activities,<br />
transboundary emissions have a<br />
significant impact.<br />
• Significant residential<br />
populations are present near<br />
MAF industrial area.<br />
• Currently available air quality<br />
data in MAF indicate significant<br />
concentrations of some<br />
pollutants.<br />
• Over the past 5 years, the water<br />
consumption in areas serviced by<br />
estate services increased by 18%.<br />
• Per capita domestic water<br />
consumption in RAH continues<br />
to be high at about 400 L/d.<br />
