months shall cover the following aspects:

2.1.1 DATA GENERATION:

Methodology for collection of Environmental Baseline Data shall be as per the

guidelines of the Ministry of Environment and Forests.

Environmental Baseline Data shall be collected from the following attributes of the

environment.

2.1.2 AIR ENVIRONMENT

Data on air environment in the area shall be ascertained by Ambient Air Quality Survey

(AAQS) within 25km radius of project site. For rapid EIA studies, AAQ monitoring shall
