SRK Consulting: Project No: 439414 Staatsolie Pipeline EIA – Draft EIA Report Page 90 7 Conclusions and recommendations Pipelines are generally considered relatively safe and efficient conduits for fuel and are used worldwide under a wide range of conditions. The proposed Staatsolie pipeline is relatively smallscale compared to the major oil and gas pipelines and will be laid underground along most of its length. Consequently, the proposed Staatsolie pipeline is predicted to have few and limited impacts, which can be effectively mitigated. The EIA has examined the available project design information and drawn mainly on available (secondary) baseline data to identify and evaluate environmental (biophysical and socio-economic) impacts of the proposed Staatsolie pipelines. The EIA Report aims to inform decision-makers of the key considerations by providing an objective and comprehensive analysis of the potential impacts and benefits of the project and has created a platform for the formulation of mitigation measures to manage these impacts. This chapter presents the general conclusions that have been drawn from the EIA process and which should be considered in evaluating the project. It should be viewed as a supplement to the detailed assessment of individual impacts presented in Chapter 6. 7.1 Principal findings There are a number of minor or less significant impacts associated with the pipeline. If recommended mitigation measures are adopted, these impacts are not expected to be significant nor long-term. They include groundwater, visual, air quality, noise and vibration, land and river use and climate change impacts. A summary evaluation of the potentially significant impacts that will result from the proposed project is presented below. Table 7-1 summarises the potentially significant impacts and their significance ratings before and after application of mitigation and/or optimisation measures. Relevant observations with regard to these impacts are: • Impacts on surface water quality in the Suriname River are most likely the result of construction activities, notably the planned disposal of surplus drilling mud into the Suriname River and runoff of sediments or contaminated water from construction sites. Impacts on water quality are expected to be limited due to the tidal nature of the river (resulting in vigorous mixing and dilution capacity), the expected small volume of pollutants and the absence of sensitive habitats in the area; • Impacts on terrestrial and aquatic habitat quality will be confined to the construction phase when vegetation clearing for drill pads and assembly areas and filling of land to extend drill pads into the river will occur. Impacts on habitat quality are expected to be limited as construction sites are very smalland located in highly disturbed areas of no conservation value; • The project will generate only limited employment. It is not expected that new employment will be created by the pipeline construction. Rather, existing employment at the contracted firms will be supported. Indirect employment generated through the (local) purchase of materials and services and expenditure in the local community is expected to be small; and • The movement of construction vehicles, laying out of pipeline strings in the river and the transport of construction materials, equipment and workers to and from the work sites may affect road and river traffic. However, the impact is considered limited as additional (local) road traffic due to the pipeline construction is expected to be minimal, and river-based activities related to the pipeline project are only locally restricted for short periods of time.

SRK Consulting: Project No: 439414 Staatsolie Pipeline EIA – Draft EIA Report Page 91 The EIA also considered the impacts of possible non-routine events, or “risks”, such as the accidental release of drilling mud during construction (frac-out) and the accidental release of hydrocarbons due to pipeline rupture or leakage. The significance of these impacts, should an incident take place, was assessed and deemed to be very low following the implementation of recommended mitigation measures. Table 7-1: Summary of potential impacts resulting from the Refinery Expansion Project Impact POTENTIAL IMPACTS Surface water pollution due to construction activities Loss or deterioration of terrestrial and aquatic habitat due to construction activities Significance rating * Before mitigation Very Low Low After mitigation Insignificant Very Low Employment creation Very Low Very Low Disruption of road and river traffic Very Low Very Low Key mitigation/optimisation measures • Consider staggering release of the surplus drilling mud over time, and at different locations, preferably in fastflowing conditions and deeper river sections to aid the rapid dispersion of the bentonite. • Consider disposing of some surplus drilling mud on land. • Comply with Project effluent quality standards for stormwater discharge. • 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. • Minimise landtake and associated vegetation clearing / filling in the river. • Avoid disturbance to areas outside of construction areas as far as possible. • Consider maximising the employment of local workers and formalise this policy in Staatsolie’s HR guidelines and contracts. • Work closely with the local community to identify and communicate required skills and resources that the local community could provide. • Consider implementing labour-intensive rather than capital-intensive work methods wherever possible. • Consider purchasing resources from Surinamese sources wherever possible. • Attempt to time the transportation of construction workers and materials to avoid peak traffic hours as far as possible. • Ensure compliance with international and national (MAS) safety standards and procedures for barge and tanker operations. POTENTIAL RISKS (note: rating reflects impact significance should an incident take place) Accidental release of drilling mud during construction (frac-out) Low Very Low To reduce the probability of an incident (does not affect significance rating): • Monitor drilling pressures and penetration rates. Ensure that mud pressure is optimal to penetrate the formation. To reduce the impact in the event of an incident: • Visually monitor the areas around the drilling site for signs of drilling mud leakage, especially while drilling shallower sections near the entry / exit points. • Compare the estimated and actual volume of drilling mud returns, to detect escaping mud. • Cease drilling operations if returns of drilling mud decrease or if a surface release of drilling mud is detected, to determine what actions need to be taken, in line with stipulations in the EMP and the spill response plan.
