Health and Safety Guidelines of 2007) and Labor Code of Vietnam. The Plan shall address health and safety hazards associated with construction activities (e.g., excavations, working at heights, etc.), establishment and operation of construction/worker’s camps, use of heavy equipment, transport of materials and other hazards associated with various construction activities.
g. Emergency Response Plan to prevent, mitigate, respond to and recover from emergency events that could occur due to project activities such as accidents, spills of hazardous substances, fire, extreme weather events, and other crises.
Construction
1. Wastewater from concrete batch plants (CBP) a. Prior to operation of CBP, construct settling/retention ponds with sufficient specifications/capacity for treatment of wastewater (e.g., from washing of equipment such as mixer drums, trucks and chutes; contact storm water, etc.)
b. Properly operate and maintain settling/retention ponds to ensure effluent quality meets applicable QCVN 24:2009/BTNMT (National Technical Regulation for Industrial Wastewater) Part of contractor’s bid cost Contractor MAUR/PMU2, CSC, PMISC

2. Air quality impacts due to gaseous and dust emissions a. Strictly implement approved Dust Control Plan;
b. Wherever possible, use electrically- powered equipment rather than gas or diesel-powered equipment;
c. Position any stationary emission sources (e.g., portable diesel generators compressors, etc.) as far as is practical from sensitive receptors;
d. Use only vehicles and equipment that are registered and have necessary permits;
e. Burning of wastes generated at the construction sites, work camps and other project-related activities shall be strictly prohibited;
f. Construction equipment and vehicles shall be well-maintained and shall meet national QCVN emission standards;
g. Specify the use of clean fuels such as ultra-low sulphur diesel in dump trucks and other heavy-duty diesel vehicles and/or equipment, in conjunction with the use of particulate trap control devices, as well as catalytic converters, to avoid excessive diesel emissions.
h. Keep stockpiles moist and cover vehicles with tarpaulin sheets or other suitable materials to minimize dust emission and prevent spillage of Part of contractor’s bid cost Contractor MAUR/PMU2, CSC, PMISC

materials (e.g., soil, cement, stone, sand, aggregates, excavated soil, construction wastes, etc.).
i. Provide temporary covers (e.g., tarpaulins, grass, etc.) on long term materials stockpiles.
j. Concrete mixing areas at the Depot site shall be located at least 300 m from the nearest residential area.
k. Clean road surfaces of debris/spills from construction equipment and vehicles.
l. Install temporary fencing or barriers around particularly dusty activities in vicinity of sensitive receivers;
m. Ensure availability of water trucks on site and if the works surface and access roads near sensitive receptors (i.e., residential areas, roadside tea and food stalls and other sensitive receptors) are dry and spray water on the exposed surfaces to reduce dust emission.
n. All construction equipment and machinery shall be fitted with emission control equipment in full compliance with the national (QCVN) and local regulations.
o. Fuel-efficient and well-maintained haulage trucks will be used to minimize exhaust emissions. Smoke belching vehicles and equipment shall not be allowed and shall be

p. Impose speed limits on construction vehicles to minimize road dust in areas where sensitive receptors are located.
q. Locations for stockpiling material at the depot area will be at least 100 m from the nearest residential sensitive receivers.
r. Undertake immediate repairs of any malfunctioning construction vehicles and equipment.
s. Discourage idling of engines
t. Provide prior notification to the community on schedule of construction activities
u. Implement community complaints hotline
3. Noise impacts due to operation of construction equipment/ vehicles and various construction activities a. Strictly implement Noise Control Plan
b. All construction equipment and vehicles shall be well maintained, regularly inspected for noise emissions, and shall be fitted with appropriate noise suppression equipment consisten
