Environmental Safe Guard:
A number of required documents and plans have been prepared by the Contractors and the Consultants, and submitted for review and approval as per the contractual requirements including Contractor’s Environmental Management Plan (CEMP), Quarry Management Plan (QMP), records of Complaint Registry, and records of Disposal Agreement for spoil, and Land Lease Agreement for quarry sites. Additionally, the contractors make agreement with landowners to allocate dumping areas for spoil disposal areas including excavated and residual-milled materials.
Throughout the execution, the CEMPs have been revising based on the actual detailed construction methodologies, work program, workforce management and construction activities by the respective Contractors and viewing by the Supervision Consultants and the PMO. The updated CEMPs are being addressed to the follows:
- Assessment new sensitive areas that may cause risk to communities, workers and passer-by such as crusher areas, borrow pits, and new campsites areas;
- An appropriate environmental program;
- Specify the mitigation measures to be implemented and monitored
- Other associated plans also prepared such as crusher environmental management plan and Covid-19 response plan.
Monitoring activities were conducted by site visits using inspection checklists of Environmental and Safety to review the Contractors’ compliance and identify potential environmental issues that may represent a risk to the project implementation. Generally, mitigation measures have been implemented and applied by the Contractors including wastewater and solid waste management, traffic management, measurements to reduce dust, noise and vibration, fire control, Covid-19 control and prevention.
Thought the PMO have detailed instruction on collection and dumping spoil and solid waste and the issues of waste disposal was alsobrought up at the several meetings, the construction waste were still dumped in illegal sites, typically waste was dumped beside the road side at chainage 439+000 and 450 + 000 by CW2, which block the drainage system and part of the road, and cause to locality flooded and unsafety for the passer-by. The Supervision Consultants and Contractors are advised to monitor and prompt actions responding to this matter.
Additionally, improper management and storage of hazardous materials (bitumen) still have been observed, at Km 215 (Tiunka lay down area). The contractor is required to handle and perform bitumen and other hazardous materials properly to avoid spillage. To identify if there are any negative impacts of hazardous wastes to water sources, underground water near the area also may need to be sampled and analyzed.
