Abstract/ Executive Summary:

The study has been conducted at USA Agro and Auto Bricks Ltd. at Lebukhali, Dumki Upazila under Patuakhali district. The purpose of this study is to find out the potential environmental impact during the construction operation and maintenance phase of the project and suggest effective mitigation measures to reduce negative impacts. Data necessary for the study has been collected through both primary and secondary data sources by literature review, Household Questionnaire Survey, Focus Group Discussion, and Key Informant Interview of surrounding people. Environmental Impact is analyzed through the calculation of Environmental Impact Value and Leopold matrix. Environmental Impact Value (+2) shows that the impact of the brickfield is low positive. Leopold matrix shows the pre, during and post construction value as 2.28, 1.56 and 1.82 where pre-impact is moderate, during and post-impact is low. Our estimated result shows that the negative impact of the project is minimum.

Objectives:

The main purpose of this study is to find out the adverse environmental impact during the construction operation and maintenance phase of the project and suggest mitigation measures to the negative impacts.

Methodology:

Study area The proposed project located at the southern coast of Lebukhali union in Dumki upazila under Patuakhali district of Bangladesh. Its geographical coordinates are 22° 27' 0" North latitude and 90° 20' 0" East longitude. The location is easy communicated both in road and river ways. It is bounded by Bakerganj upazila on the north, Patuakhali Sadar and Bauphal upazilas on the south, Bauphal Upazila on the east, Mirzaganj upazila on the west. Lebukhali is situated beside Paira River (BBS, 2015). Data collection This study was conducted based on available primary and secondary data. The primary data was collected through a Household Questionnaire Survey, Focus Group Discussion and Key Informant Interview. A total 50 questionnaire survey, 2 FGD, 10 KII were conducted for primary data. For questionnaire survey total 50 people were selected randomly in the study area. The household questionnaire survey was formulated with both open-ended and close-ended questions to attain more in-depth information from respondents. Local knowledgeable persons including community representatives, traders, teachers, and political leaders were interviewed individually to know their perception about the project. Secondary data and information for this study were collected from relevant books, daily national newspapers, journals, and websites. Data processing and analysis Collected data from different sources were analyzed by the help of Microsoft Office Excel sheet and SPSS software. For impact assessment, there used both Environmental Impact Value (EIV) and Leopold Matrix. The environmental impact value is calculated by the equation (Wilson, 1998; Saha, 2007).

Achievement/Findings:

After properly evaluation of environmental impact, the Environmental Impact Value was found as “+2”, that means this project has a positive impact on different environmental components. Evaluation of Leopold matrix shows that the pre, during and post construction value as 2.28, 1.56 and 1.82. These values indicate the project’s pre-construction stage impact is moderate, during and post- construction stage impact is low on different environmental components. Though this brick kiln has some negative impacts on the environment, socio-economic condition and livelihood pattern of peoples in this area will be dramatically changed due to this brick kiln. This brick kiln will create more employment opportunity for local people. As more people getting the opportunity to work there and there will also create small to large business opportunity based on this projects so the economy of this area will be developed and people’s lifestyle will be standard. The major negative Impacts of this project are a loss of trees, impact on air quality, impact on surface water quality, loss of agricultural lands, loss of vegetation, loss of agricultural topsoil, impact on ecological resources, the health impact of workers and local people, noise generation from construction activities, etc. The magnitude of these negative impacts can be easily reduced by taking proper and planned mitigation measures. By evaluating different environmental impacts it can be said the negative impact due to this project is not so high. So the project can be implemented.
