Movement of Barges only within the designated areas in the river. Included incivil workscontractCompensation by establishment of Padma protected sanctuary Establishment of Charland Visitor Center Increase coverage of open surface area by planting grass and creepersso that washing away of materials from sloped surfaces would bereduced to a significant extent. Store the construction materials containing fine particles, e.g. limestoneor laterite, in an enclosure such that sediment laden water does notdrain into nearby watercourses, but rather percolates slowly into the soil. Provide fences, sediment barriers etc., to prevent siltation in theconstruction sites. All equipment should be properly maintained in compliance withmanufacturers guidelinesEnsure the quality of wastewater to be disposed into adjacent waterbodies,;Compensate the financial loss associated with the disposal of suchwaste water into private ponds/landsDischarge sediment laden construction water into settling lagoons ortanks prior to final discharge.Ensure sufficient retention time to allow waste water disposal from landfilling sites in the adjacent lands with required SS levelDisposal dredge materials will be carried out in accordance with theDredge material management plan.
