Question

oes a reference site selected for a baseline study in the Environmental Impact Q7. How d Assessment? (3 marks) 08. What factors are to be considered in devising a monitoring program for Environmental Impact Assessment? (4 marks)

Answer 1

3. list of constraints to be considered for selecting a sanitary landfill site are as follows.-

i) haul distance

ii) location restriction/available land area

iii) surface water hydrology

iv) soil condition and topography

v) local climatic and environmental conditions

6. The primary purpose of weighting network is to subjectively measure the intensity as well as the effect of noise. These weighting networks (designated as A,B,C,D)are used in sound level meters to differentiate noise/sound against different frequencies. often, they are used in measuring residual noise in audio equipments, broadcast systems and telephone circuits.Basically, what they do is that they concentrate on audible spectrum (for humans) and try to attenuate the other parts that are less percievable to human ears thereby making the hearing experience more humanly.

7. There are no hard and fast methods for determining terms of reference(TOR) which will be suitable for every study. However, there are some rules which should be considered when preparing TOR for the EIA of any developmental project.

• The study should focus on the major issues and the most serious likely impacts.
• The study should identify the relevant natural resources, the eco-system and the population likely to be affected.
• Direct and indirect impacts must be identified and any particularly vulnerable groups or species highlighted.
• should provide the degree of risk or confidence and the assumptions on which conclusions have been drawn.
• nevertheless, existing site conditions/factors which may have negative impact on site must have to be considered
