Environmental Impact Assessment is meant to be used as planning and decision-making tool. It is supposed to be objective and unbiased, and it is not meant to either promote or block the implementation of a proposed project. The greatest benefit of Environmental Impact Assessment (EIA) is that environmental concern must be examined thoroughly, and the chances for severe or unexpected damage due to a construction project are significantly minimized. The focus of the research paper is to design a more flexible, effective and straight forward road map to performing Environmental impact assessment (EIA) for specific projects before implementation: it is ideal that EIA be perform to assess the feasibility of selected projects in order not to destroy the already existing baseline environmental conditions. In this research paper, attempt has been made to develop a step by step methodology needed to conduct an Environmental Impact Assessment for some selected projects including, dam construction, road construction, integrated solid waste management scheme, e.t.c. Aims: Some of the main aims of environmental impact assessment studies are as follows: (1)To close down the harmful effects of proposed project development so as to achieve environmental sustainability thereby preserving the existing ecological balance. (2)To protect the human, plant, and animal population existing before the commissioning of a proposed project. (3)To preserve the aesthetic characteristic of the physical environment of a place before the project development. Objectives: Some of the main objectives of Environmental Impact Assessment (EIA) studies are as follows: (1)To analyze all the positive/negative impacts of a project on the total environment, on a rational basis. (2)To select a suitable site for the project taking into real consideration environmental impact and cost benefit ratio analysis. (3)To obtain necessary clearance and approval for the project proposal based on environmental consideration. (4)To select suitable raw materials for the project based on environmental considerations. (5)To suggest suitable remedial modification/waste management methods in the project design and related activities to minimize the level/impact of pollution at source.
