• Develop (or adapt and implement) procedures for the safe transport, handling and storage of potential pollutants.
• Design and construct hazardous material storage facilities, especially fuel storage, with suitable impermeable
materials and a minimum bund containment capacity equal to 110% of the largest container.
• Ensure all on-site staff is trained in the use of spill prevention measures.
• Comply with any additional mitigation measures contained in the EMMP.

During operation, the sealed pipelines will lie up to 30 m below the Suriname River and not be in
direct contact with the river. Under normal circumstances, they will not have an impact on surface
water (see Section 6.7.2 for potential impacts of accidental releases of hydrocarbons).
6.4 Potential impact: Loss or deterioration of terrestrial and aquatic
habitat during construction
Potential impacts of routine activities on terrestrial and aquatic habitat quality during pipeline
construction may result from:
• Vegetation clearing for the establishment of drill pads and assembly areas; and
• Filling of land to extend drill pads into the river 34 .
HDD will require the construction of up to four drill pads for the placement of the drill rig at the entry
point of each drill section. Each of the four drill pads measures up to 2 500 m 2 ; a combined area of
up to 10 000 m 2 . The assembly area will essentially be a long narrow corridor along which the
pipelines can be laid out, adjacent to local roads in the area.
All construction sites are located in highly disturbed areas that contain no or very limited secondary
vegetation nor vulnerable, rare or endangered plant species. Similarly, wildlife species present are
commonly associated with human presence.
The riverbank has been modified by the development of jetties, filling into the river, possible bank
stabilization in places, construction of inlets and industrial facilities. The fill required for the drill pads
is relatively minor compared to existing structures in the river in this section, many of which extend
further into the river.
The potential impact of vegetation clearing and filling on habitat quality will be localised and of low
intensity. The impact is expected to be of medium-term duration as vegetation will either grow back
or a new equilibrium is likely to establish, in the absence of subsequent disturbance from other
activities. The potential degradation of habitat quality during the construction phase is therefore
assessed to be of low (negative) significance and with the implementation of mitigation is reduced
to very low (negative).

Key mitigation measures:
• Minimise landtake and associated vegetation clearing / filling in the river.
• Avoid disturbance to areas outside of construction areas as far as possible.
• Comply with any additional mitigation measures contained in the EMMP.
34 Trenching will be limited and is not expected to have impacts on terrestrial or aquatic habitats as it will be done in areas that
are already severely degraded (Bruynzeel site, SOL and OGANE).
