Impact Rating Criteria
Following criteria has been considered for rating of the impacts.
For each impact area, the magnitude and importance of impact has been rated on
the scale of 1 to 3
Magnitude
• High Impact = 3
• Moderate Impact = 2
• Less Impact = 1
Importance
• Very Important = 3
• Moderately Important = 2
• Less important = 1
Ranking Criteria
Keeping in view, seven major activities having an impact on the environment and
considering nine major impact areas (as shown in Tables 7.2 & 7.3) the criteria for
overall ranking of the secured landfill facility is developed as follows:-
Total Score, if
Above 500
The WMF is having very high adverse Impact
500 - 100 The WMF is having Moderate Adverse Impact
Below 100
The WMF is having Less Adverse Impact
WMF: Waste management facility
7.4.3 Weighted Impacts Without Considering Mitigation Measures
Based on the criteria for rating the impacts, the weighted impacts without taking any
mitigation measures have been presented in Table 7.2 for major activities in the
