Steve Willson, president of Chevron Bangladesh- a US oil and gas exploration company, yesterday said Chevron has 'obtained all permits and approvals' required for conducting 3D seismic survey in Lawachhera Reserve Forest in Kamalganj in Moulvibazar and the company is in 'full compliance with all applicable laws and regulations in Bangladesh'. He reiterated that Lawachhera forest will remain secure and safe during the survey and a monitoring team has been formed to supervise the seismic work in the forest. He said, the company has obtained Initial Environment Examination (IEE) clearance and Environmental Impact Assessment (EIA) clearance from the Department of Environment (DoE). Permission to do seismic survey in the reserve forest was noted in the government gazette also, he said. He was exchanging views with local journalists at a restaurant in Moulvibazar town yesterday. Willson said, Chevron is working in partnership with Bangladesh government and Petrobangla, state owned oil and gas company. He said, an extensive EIA study has been completed by an international environmental consultant (SMEC) working with some local organisations. He added that Lawachhera Reserve Forest area has been divided into three sections- Red Zone, Yellow Zone and Green Zone. Red Zone has been marked for 'no work', avoided completely. The Yellow Zone has been marked where work will be done with 'extreme caution' and in the Green Zone has been marked as 'less sensitive, fewer restrictions', Willson said. Experts are of the opinion that this survey will be harmful for the forest, rich in natural resources and wildlife. Different organisations working on environment are holding agitation programmes like rally and human chain to stop any seismic survey in Lawachhera.
