Review: Definition of EIA3
Environmental Impact Assessment is : A formal process for identifying:
The likely effects of activities or projects on the Environment and on human health and welfare.
Environment is broadly interpreted as physical, biological, and social.
In EIA, the term “impacts” is used instead of “effects of activities.”
![Page 4: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/4.jpg)
Terms of Reference The TOR’s provided is used to guide the preparation and
format of the EIA Report; It identifies the environmental aspects which required
monitoring; The information which is needed to effectively assess the
project impacts and inform the decision-making process;
It makes provisions for public involvement in the process;
Indentifies project alternatives which should be examined;
It stipulates format of studies to be carried out (e.g. methodologies and approach, time & space boundaries);
It identifies the requirements for mitigation and monitoring.

What is an impact?5
The impact of an activity is a change from the baseline situation caused by the activity. The baseline situation is the existing environmental condition in the absence of activity.
The baseline situation is a key concept in EIA. To measure an impact, you must know what the baseline situation is.
![Page 6: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/6.jpg)
Assessing ImpactsWhen collecting baseline data, the data must provide information which allows the EIA specialist to assess:- long term and short term impacts direct and indirect impacts cumulative impacts beneficial impacts and adverse impacts
![Page 7: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/7.jpg)
Impact CategoriesExamples of direct impacts include:
increased noise and dust decreased air quality, decreased water quality, increased solid waste, increased employment (3000 jobs at peak
construction), increased training and education, increased infrastructure development.
![Page 8: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/8.jpg)
Impact CategoriesIndirect impacts include:
increased traffic, increased commercial activity increased employment small business development
Cumulative impacts include: Are those which provide incremental
contributions to existing conditions produced by existing industries and socio cultural activities

The Baseline Situation9
•In characterizing the baseline situation, many environmental components are of interest.
•The components of interest are those that are likely to be affected by your activity—or upon which your activity depends for its success
Water Quantity of Pollutants, quality.
Soils Erosion, soil type, crop productivity
Flora Composition and density of natural vegetation, productivity, key species
Fauna Population size, habitat health, sensitive, rare or commercially valuable species
Noise Sound pressure levels
Air Quality, Quantity of Pollutants

4 Components of the Baseline Environment
The Physical and Chemical Environment The Biological Environment The Human (Social Environment) The Human (Economic Environment)
![Page 11: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/11.jpg)
Sampling Method Sampling design involved the collection of historical
data from published sources and EIA documents and well as the conduct of field surveys.
Historical data will be used to establish past trends observed.
Real time data collected through sampling will be used to determine the current environmental status as well as validated the historical data sets.
Focus was placed on collecting data necessary for determining the impact of CGCL’s proposed operations.

Defined Study Area The immediate study area includes all of
the land, air and sea space within a five kilometre radius of the proposed plant site
The wider study area was defined as
areas directly, or indirectly affected by proposed CGCL activities and encompasses all of that area within a 10km radius of the project site.
![Page 13: The EIA Process and Baseline monitoring](https://reader035.vdocuments.net/reader035/viewer/2022081422/56816413550346895dd5c211/html5/thumbnails/13.jpg)
