8.3 Sub plan detail for the Enhancement Works on Road Conditions at Resettlement site -environmental

All Sub-Plans in this section refer to Enhancement Works on Road Conditions atResettlement site unless otherwise mentioned.

SP01 Erosion and Sediment control

An open ditch will be installed around the road side to collect and divert run-off. Initial erosion and sediment controls, such as sediment ponds shall be installed prior

to or as early as possible after the commencement of vegetation clearance /earthworks.

Areas within the construction areas not required to be disturbed by constructionactivities will be maintained in their existing condition.

Steeper embankments on the boundary of the site will be laid with grass to improvesoil stability. Where available re-vegetation with native species will be selected.

Rip-rap will be installed on outlets of pipe culverts.

SP02 Water Availability and Pollution Control

Equipment service and storage workshops will have impermeable flooring andcollection sump.

Implementation of solid and septic system waste management systems, such asproper location, containment and disposal of construction debris and constructionworker camp trash (e.g., use of watertight dumpsters and weekly trashcollection/removal), and appropriate location (at least 30 m from drainage courses orother sensitive areas) and containment of septic systems.

The contractors shall provide sanitation facilities/toilets with septic tanks withsufficient capacity to handle and treat domestic wastewater generated by workers. • Alicensed contractor will be used to remove all waste when septic tanks reachcapacity. NNP1 will be notified and will be present on site when discharging anyseptic waste.

Warning signs will be placed in areas of hazardous material use or storage and along



drainages and storm drains (or other appropriate locations) to avoid inadvertenthazardous material disposal.

Construction materials and chemicals must be properly disposed of.

SP03 Emission and Dust Control

Speed limits (20 km/h or less) will be imposed on all construction vehicles to minimizedust

Unsealed Project roads, compounds and work areas accessible by vehicle will beregularly sprayed with water to suppress dust when a dust hazard exists.

Exposed surfaces will be progressively rehabilitated within one month following thecompletion of use to reduce site dust and erosion hazards.

The burning of waste materials shall be minimized on site and only take place underthe following conditions:(i) Burning will only be undertaken in the presence of a trained fire protection officer.(ii) Burning will not be undertaken during severe wind conditions.(iii) Appropriate fire protection equipment will be available on-site during the burn.(iv) Burning will be undertaken at a safe distance from vegetated areas.(v) Burning will not be undertaken near a village.

Dust monitoring shall include visual assessment at sensitive receptors (e.g.,community, labour camp, schools) around construction camps to ensure thatassociated impacts are being adequately addressed.

SP05 Waste Management

During construction: Dumping of waste into watercourses, agricultural land and surrounding areas

is highly prohibited. A sufficient number of waste containers or similar one will be made available at the

construction site. Waste containers will be marked clearly for “Hazardous Waste” and for “Non-

Hazardous Waste” for separation and sorting of waste. Construction waste will be minimized by applying the waste minimization hierarchy

principles of ‘Avoid/Reduce/Re-Use/Recycle/Dispose’. Any waste material that isunable to be re-used, re-processed or recycled will be disposed at a facility approved toreceive that type of waste.

Hazardous waste such as paint and solvent containers will be disposed of accordingto appropriate best practices.

Waste will be stored in appropriate facilities (e.g. bins, stockpiles), with hazardouswaste stored away from streams and rivers in secure areas.

Secure lids will be fitted to bins that store food waste to prevent scavenging by birdsand animals.

The site will need to collect construction waste materials such as metal offcuts,concrete, debris, plaster and plastics and removed by the construction company.

Pit toilets will be installed for construction Workers, and they will be instructed to use



these facilities.SP06 Hazardous Material Management
