1.9 Compliance with National Environmental Laws

The environmental legislation of GOB emphasises reducing the negative impacts of development projects and enhancement of the positive impacts. This conforms to Bangladesh Environmental Conservation Act (BECA) 1995 and Bangladesh Environmental Conservation Rules (BECR) 1997. The Bangladesh Environment Conservation Act of 1995 (BECA '95) is currently the main legislation in relation to environment protection in Bangladesh. This Act is promulgated for environment conservation, environmental standards development and environment pollution control and abatement. Environmental Conservation Rules (1997) promulgated under the Environmental Conservation Act of 1995 (so far there have been three amendments to this set of rules. The Environment Conservation Rules of 1997 has provided categorization of industries and projects and identified types of environmental assessments needed against respective categories of industries or projects. The Department of Environment (DoE) executes the Act under the leadership of the Director General (DG). Prior permission is required from DoE for extraction and production of mineral resources under this act. Before any new project can go ahead, as stipulated under the rules, the project promoter must obtain Environmental Clearance from the Director General. Failure to comply with any part of this Act may result in punishment.

1.10 Compliance with ADB’s Safeguard Policy Statement

ADB has issued Safeguard Policy Statement (SPS) in 2009. ADB emphasizes assisting developing member countries to pursue environmentally sustainable growth and is also committed to ensuring the social and environmental sustainability of the projects. In this context, the goal of the SPS is to promote the sustainability of the project outcomes by protecting the environment and people from projects’ potential. An IEE report with Environmental Management Plan (EMP) was prepared and submitted to ADB. The EMP was incorporated into the tender documents and has then become a part of the contract. The cost for the implementation of the EMP has been included in the Contract. The project is also in conformity with the guideline of ADB i.e. Safeguard Policy Statement 2009.

The objectives of ADB’s safeguards are to:

i) avoid adverse impacts of projects on the environment and affected people, where possible;

ii) minimize, mitigate, and/or compensate for adverse project impacts on the environment and affected people when avoidance is not possible; and

iii) help borrowers/clients to strengthen their safeguard systems and develop the capacity to manage environmental and social risks.

Safeguard Policy Statement applies to all ADB-financed projects and their components including investment projects funded by a loan and/or grant. ADB do not finance projects that do not comply with its safeguard policy statement.

1.11 Environmental Clearance

The environmental clearance for the project was obtained from Department of Environment (DoE) on 30 April 2013 vide their memo no. DOE/Clearance/4042/2009/97. Subsequently renewal of the environmental clearance certificate is going on from DoE.

1.12 Key Findings in IEE

BGFCL will maintain standard quality of implementation of the program with due consideration to standing rules and regulations. Well drilling and gas process plant construction and operation usually have a temporary environmental impact compared to that of the other industrial projects. The use of best engineering and management practices, mitigation procedures and control will contribute positive impact on environment. Project construction and operational activity have minimum adverse impacts on the environment. The most important measure to achieve a good level of environmental acceptability of the project is adoption of best practices

in design and construction. Avoiding environmentally sensitive location should be an integral part of the process.

The potential environmental impacts of the projects components covered by the IEE are insignificant, and temporary, which will mostly occur only during the operational stage. All the potential environmental impacts can be mitigated to an acceptable level by adequate implementation of the measures.

1.13 Environmental Management Plan

The Initial Environmental Examination (IEE) contained an Environmental Management Plan (EMP) for mitigation measure in view of the possible impacts due to project activities. The EMP also includes a monitoring plan for taking corrective measures. Implementation of EMP would minimize the effect of negative impact and increase the benefits of the positive impacts. EMP mitigation measures are defined in the institutional responsibility table. The Environmental Management Plan contains associated monitoring programs during project implementation period.

1.14 Institutional Arrangement for Monitoring and Compliance

The monitoring has carried out by the Executing Agency (EA). Project Implementation Unit (PIU) personnel stay at site full time during project operation period to oversee the activities. In addition EA has Environment and Safety department headed by Deputy General Manager to oversee the environment and safety activities of the company including the projects. During project operation environment and safety departmental personnel visit project area every week and consult with contractor’s personnel to take necessary steps for protection of the environmental pollution resulting from their activities. Also, a monitoring firm (Mia Environmental Monitoring Center) was engaged to monitor and tests the environmental parameters time to time. They have collected samples from the project area and conducted test in laboratories.

2.4 Mitigation Measure

2.4.1 Air Quality

Construction materials at the site are properly covered while hauled and stored, roads properly cleaned and water sprayed in order to minimize concentration of dust in air when dust increases. Vehicle movement to and from the site are properly managed to ensure that is does not significantly aggravate the traffic problem and air pollution. Stone (aggregate) crushing activities are properly done in fine tune batching plant which is far away from the construction site and not allowed within the project premises. Health status of all workers is monitored regularly at the Health Center established at the project site.

2.4.2 Water Quality

The human wastes from the labour camp are appropriately disposed off through construction of sanitary latrines connected to appropriately designed septic tank system (consisting of septic tank and soakage pit). Wastewater generated from different construction activities is not likely to be significant in volume. Disposal of such wastewater are carried out by draining them in shallow pits (1 to 1.5 m deep) dug in the ground at appropriate locations, and filling them up with sand at the end of the construction phase. In all cases, the wastewater streams are separated from the storm water stream, which is disposed off separately utilizing the storm water disposal system at the project site.

2.4.3 Noise Level

- Used “quiet” equipment (i.e., equipment designed with noise-control elements);

- Routed truck traffic away from noise-sensitive areas, where feasible;

- Installed sound barriers for pile driving activity, where practicable (e.g., use an acoustic curtain or blanket around the point of impact);

- Unnecessary vehicle movement are avoided

- Switch off the engines while remain unused.

2.4.4 Solid Waste

The solid wastes of domestic nature generated mainly in the labor sheds are collected and stored separately (i.e., without mixing it with construction wastes/debris) in appropriate containers within the construction site. The solid wastes generated during project operation period will be collected properly and deposited to designated place within the company’s own premises.

3.6 Progress of Work

Drinking water monitoring: Drinking water sample was collected from supply water for analyzing.

Under ground water monitoring: Ground water sample was collected from supply water for analyzing.

Noise level monitoring: Noise level monitoring is also necessary during construction period, because use of heavy construction equipment may increase the noise level at the work location. So, Noise level data were collected from selected locations.

Waste management and process waste monitoring: Disposal of construction debris away the site and their appropriate disposal sanitary landfill are ongoing. Hazardous waste and non-hazardous waste are also disposing by proper way.

Trees cutting: The project site is in bare field. So, there was no scope of tree cutting.

Others: There is no significant impact on the existing road network in the project area. Major transportation of plant and construction material are done by the road with unloading of materials by crane owned by the contractor which is within the existing BGFCL area.

Health and Safety: The general health and safety of workers is safeguarded with the provision of medical and health facilities on-site, the provision of personal protection equipment (hard hats, ear plugs, masks as required). There is an emergency response system and workers and supervisors are received training on any accident and immediate medical facility in its own round the clock medical center.

3.7 Statement on Site Inspection

During the project operation, project office personnel are engaged full time at site to oversee the contractor’s activities. Environment and Safety departmental personnel also visit the project area every week and consult with contractor’s personnel to protect environmental pollution resulting from their activities. One complaint was received against crops damage and which was met up through distribution of cash compensation. No noncompliance notice was issued by BGFCL.

3.8 Grievance Redress Mechanism

Grievance Redress Mechanism had been established to ensure stakeholders participation in the implementation process. Through public consultations, the AP’s had informed that they have a right to grievance redress from BGFCL. The AP’s had called upon the support of the RP Implementing committee engaged to implement the RP to assist them in presenting their grievances or queries to the GRC. Other than disputes relating to ownership right under the court of law, GRCs had reviewed grievances involving all resettlement assistances, relocation and other supports.

The EA had hanged two grievance receiving boxes at the main gate of project locations (Sarail & Bohdol). The affected 7 (seven) farmers of Sarail Location claimed that some crops (Paddy field) of their land adjacent to boundary wall had been damaged at the time of Drill Stem Testing (DST) operation of Well no 23.

GRC consulted with Sarail Union Parishad Chairman, Member, Agricultural Extension Officer (Sarail Upazilla) and 7 AP’s. After consultation, the GRC fixed up the value of the damaged crops Tk 31,365.00. All AP’s were invited on 28.02.2017 at BGFCL’s head office and BGFCL distributed Tk. 31,365.00 among the 7 (Seven) AP’s as cash compensation.

Chapter 4: Recommendation and Conclusion

The environmental monitoring report is consist of environmental monitoring reporting based on measured ambient air, noise, underground and surface water quality parameters. The work has been done in laboratory. Noise quality was done by noise level meter. House-keeping is also in good condition at the project site. All solid, liquid and hazardous waste are disposed into the designated container at the plant site. Most of the solid wastes are disposed by landfill. The usable solid wastes are handed over to proper party for recycling. Liquid hazardous waste is conserved and properly clean of the storage area. Hazardous waste is kept at designated places by labeling.

Finally it can be concluded that the project areas has minor detrimental impact for short period on the environment in terms of ambient air and ambient noise during the construction period. The plant provides a good working environment for the workers.
