All appropriate licenses and consents of construction should be obtained on time. The key measures to be implemented are as follows: No Issues/Risks Mitigation Measures 1 Waste must be collected and dumped at approved sites. General Site Drainage system must be drained regularly to ensure the Management site is always dry The dynamic electric network and the lighting system on the construction site must be separated. Measures must be in place to ensure safety with regards to electrical supply. 2 Safety with regards to Circuit breaker and breaker power must be capable of Electrical system cutting a segment or total power network of the construction area. Only proper trained and qualified workers are allowed to work on electrical devices. Provide portable fire fighting equipment at the site 3 pollution control Any seepage and wastewater arising from the works and camp sites must be collected and discharged via drain network. Septic tank toilets must be provided on site for construction workers. Wastewater from toilets will not be discharged directly into any waterbody. At completion of construction works, water collection tanks and septic tanks shall be covered and effectively sealed off Proper maintenance of construction equipment and vehicles; 4 Dust, noise, vibration - Inform the residents: Prior to commencement of work at any site, the Contractor will be required to inform the local authority and residents regarding the construction plan and potential noise and vibration that may occur from the construction activities, including measures to reduce noise and vibration. - Dust control: No burning of waste materials on site; dry sweeping of large areas is prohibited; Cover all trucks carrying loose or potentially dusty materials (soil, mud, etc.) to and from construction site; Water or sprinkle the construction areas 5

6 5 solid waste management 6 Management of Chemical or hazardous wastes periodically, especially at site located near residential area; avoid overloaded of trucks; routinely clean public roads and access routes; - Exposed soil and material stockpiles shall be protected against dust spreading, and the location of stockpiles shall take into consideration the prevailing wind directions and locations of sensitive receptors. - When needed, measures to reduce noise to acceptable levels must be implemented and could include silencers, mufflers, acoustically dampened panels or placement of noisy machines in acoustically protected areas. The Contractor must be responsible for compliance with the relevant Vietnamese legislation relevant to wastewater discharges into watercourses. Solid waste such as excavation materials wooden plates for trench works, steel, scaffolding material, site holding, packaging material should be reused/recycled where possible Non-reusable/recyclable wastes will be collected and transported to approved dumping sites. Provide bins/containers for litter and refuse collection. Waste containers shall be covered, tip-proof, weather-proof and scavenger proof. Solid waste may be temporarily stored on site in a designated area approved by the Construction Supervision Consultant prior to collection and disposal. If not removed off site, solid waste or construction debris shall be disposed of only at sites identified and approved by the Construction Supervision Consultant. Under no circumstances shall the contractor dispose of any material in environmentally sensitive areas, such as in watercourses. No burning, on-site burying or dumping of solid waste shall occur. Portable or constructed toilets must be provided on site for construction workers. Wastewater from toilets as well as kitchens, showers, sinks, etc. shall be discharged into a conservancy tank for removal from the site or discharged into municipal sewerage systems; there should be no direct discharges to any waterbody. At completion of construction works, water collection tanks and septic tanks shall be covered and effectively sealed off. Appropriate communication and training programs should be put in place to prepare workers to recognize and respond to workplace chemical hazards. Post signs prohibiting smoking, open flames and other ignition sources in areas where flammable materials are stored or used Store flammable or explosive materials such as gasoline, oil and cleaning agents apart from other materials. All hazardous substances including oil drums or containers must be properly labeled and stored to ensure that no oil or other contaminants can reach water courses or groundwater. Dispose of greasy, oily rags and other flammable materials in approved containers. Chemical waste of any kind shall be disposed of at an approved appropriate landfill site and in 6

7 7 Social disturbance, disruptions to existing services 8 Erosion and sedimentation control accordance with local legislative requirements. Used oil, lubricants, cleaning materials, etc. from the maintenance of machinery shall be collected in holding tanks and removed from site by a specialized oil recycling company for disposal at an approved hazardous waste site. Containers of used oil must be strong enough to avoid leakage, (particularly when the site is less than 10 meters from any waterways). The container must be situated within a secondary containment system (bunded), which will prevent the release of any leaked oil. Unused or rejected tar or bituminous products shall be returned to the supplier s production plant. Inform the residents: Prior to commencement of work at any site, the Contractor informs local authority and residents about construction plan and potential noise and vibration that may occur from the construction activities, and the measures to reduce noise and vibration. Discuss and negotiat with local community about water cut-off and service disruptions period Place signs around the construction areas to facilitate traffic movement, and provide safety advice and warning. The Contractor will be responsible for any damage caused by their activities to the roads and public facilities in the vicinity of the worksite. Avoid activities that generate high level of noise in sensitive time, e.g. before 7am or after 5pm. The Contractor shall follow the detailed drainage design included in the construction plans, intended to prevent storm water from causing local flooding or scouring slopes and areas of unprotected soil resulting in heavy sediment loads affecting local watercourses. Ensure drainage system is always maintained cleared of mud and other obstructions. Areas of the site not disturbed by construction activities shall be maintained in their existing conditions. Earthworks, cuts, and fill slopes shall be properly maintained, in accordance with the construction specifications, including measures such as installation of drains, use of plant cover. To avoid sediment-laded runoff that could adversely impact watercourses, install sediment control structures where needed to slow or redirect runoff and trap sediment. Sediment control structures could include windrows of logging slash, rock berms, sediment catchment basins, straw bales, storm drain inlet protection systems, or brush fences. Site de-watering and water diversions: the sediment laden water pumped from the work area must be discharged to an appropriate sediment control measure for treatment before re-release to the down stream. Build energy dispersion structure at downstream of discharge point 7

8 9 Safety and Occupational Health for Worker and the public at construction sites 10 Management of small amounts of sludge 11 Chance find Procedures Provide training and awareness raising for workers on occupational health and safety. Provide first aid kits at contractor s officeprovide appropriate safety gears to workers such as clothes, gloves, booths and hard hats and supervise the use Install fences, barriers, warning restrict access to the construction area which showing potential danger to the public Place sign boards including safety regulations at the site Provide adequate lighting at night Arrange construction materials in a neat and tidy manner. Ensure that materials loading do not obstruct access and exits to the site. Do not store flammable materials near the construction camps. During demolition of existing infrastructure, workers and the general public must be protected from falling debris by measures such as chutes, traffic control, and use of restricted access zones. Employing safe traffic control measures, including road/rivers/canal signs to warn of dangerous conditions. Ensure access to clean water and latrines by workers and provide mosquito net. Provide the appropriate fire extinguishers for the materials found on-site. Keep fire extinguisher stations clear and accessible; etc. Apply good housekeeping in the construction and/or storage sites: Keep stairways, passageways and ladders free of material, supplies and obstructions; Secure loose or light material that is stores on roofs or open floors; Keep materials at least 2m from openings, roof edges, excavations or trenches; Remove or bend over nails protruding from lumber; Keep hoses, power cords, welding leads, etc from laying in heavily travelled walkways or areas; Ensure structural openings are covered/protected adequately; Characteristics of sludge/sediment should be determined by sampling and analysis. Sludge that is heavily contaminated would require measures that go beyond the scope of these ECOPs. Lixiviate from dredged materials should not be allowed to enter watercourses without appropriate filtering or treatment. Collected dredged materials have to be processed, as per Vietnamese regulations on waste collection, to ensure safe and environmentally secure transportation, storage, treatment and management If the Contractor discovers archeological sites, historical sites, remains and objects, or graves during excavation or construction, the Contractor will carry out the following steps: Stop the construction activities in the area of the chance find; Delineate the discovered site or area; Secure the site to prevent any damage or loss of removable objects. In cases of removable antiquities or sensitive remains, a 8

9 night guard shall be arranged until the responsible local authorities or the National Administration of Culture take over; Notify the supervisory Project Environmental Officer and Project Engineer who in turn will notify the responsible local authorities and the Provincial Department of Culture immediately (within 24 hours or less); Responsible local authorities and the Provincial Department of Culture would be in charge of protecting and preserving the site before deciding on subsequent appropriate procedures. This would require a preliminary evaluation of the findings to be performed by the archeologists of National Culture Administration. The significance and importance of the findings should be assessed according to the various criteria relevant to cultural heritage; those include the aesthetic, historic, scientific or research, social and economic values; Decisions on how to handle the finding shall be taken by the responsible authorities and Provincial Department of Culture. This could include changes in the layout (such as when finding an irremovable remain of cultural or archeological importance) conservation, preservation, restoration and salvage; Implementation for the authority decision concerning the management of the finding shall be communicated in writing by relevant local authorities; and Construction work could resume only after permission is given from the responsible local authorities or Provincial Department of Culture concerning safeguard of the heritage. 9
