Def init ion of Environment and EIA
“Environment means the physical factors of the surroundings of the human beings including land, water, atmosphere, c limate, sound, odour, taste, the biological factors of animals and plants and the social factor of aesthetics”
Source: Environmental Quality Act 1974 (ACT127)
“EIA is a study to identify, predict, evaluate and communicate information about the impacts on the environment of a proposed project and to detail out the mitigating measures prior to project approval and implementation”

Dr il l ing Phases & Activit ies
Pre Drilling : Planning & Rig Mobilization - Work scope & objectives, work schedule, notification to authorities (NO O P: Notice of O perations) & drilling program approvals (cost, est. rig time, location) - Site survey (coral reefs/pockmarks) and site preparation (rig matt) - Mobilization/towing of drilling rig to drilling site, inc lude placement/positioning and anchoring. Drilling : Project Execution - heavy lifting, drilling, running casing, cementing, perforation, well logging, well completion, well testing, surface plug and abandonment. Post Drilling : Rig Demobilization - recover of anchors, rig tow

Drilling Wastes
& Disposal
C hanges to Seawater @ Water Q uality
C hanges to Seabed/ Sediments Q uality
Disturbance to Marine Fauna
• Reduction in seabed sediments quality from deposition of drilling wastes
• C hanges in seabed sediments composition and morphology (drill cutting piles)
• Effects of seawater @water quality from drilling wastes disposal into the sea or marine environment.
• Smothering effect of benthic organisms from disposal of drilling wastes & cuttings

Drilling Wastewater Discharges
Changes to Seawater @ Water Quality
• Reduction in seawater/water quality from discharges of wastewater
• Seawater @water pollution from discharges of untreated wastewater.

Changes to Seabed/ Sediments Quality
Disturbance to Marine Fauna
• Pollution of seawater column @water pollution
• Reduction in seabed sediments quality from deposition of oil/hydrocarbon.
• Mortality, physiological changes to marine mammals, birds, reptiles etc.
• Reduction in population of species level.
• Loss of fishing area

Mitigation Measures
Drilling Wastes & Disposal of Fluids-Cuttings • OBM are not allowed. • SBM contaminated cuttings cleaned & dried to 6.9%OOC limits using Solids
Control Equipment System (Shale Shakers, Cutting drier).. • Mud Management Plans (DDR & EOWR) to monitor OOC • Chemical Management Procedure to control utilization & minimize cement
returns to seabed. • Slim-hole drilling to minimize cuttings/waste Wastewater Discharge • Not exceeding 40 ppm • Installation & maintenance of OIW Separators • Wastewater Management Procedure to monitor OIW level Oil Spill Management • Oil Spill Contingency & Response Plan (Dispersant Guidelines) • Notification & Response (PIMMAG)

C onclusion • EIA is an important “tool” involving formal process used to predict
environmental consequences (positive of negative) of a project prior to decision.
• PACs, PETRONAS and Government as decision makers are made aware of
the mitigation measure proposed and able to add further control prior to project implementation
• Each EIA is unique specific to its own project concept thus each aspect impact evaluation may have different outcome
• Most important is to value findings and address each impact with specific measures to eliminate or mitigate impact to an ALARP level.

Environmental R isk Assessment
HEMP is used with following steps: (1) Environmental aspects and impact identification (2) Assess the risk of environmental aspects (3) Identify control barriers/mitigating measures to eliminate and/or reduced the risk; and (4) Identify recovery barriers/measures to mitigate and/or reduce the impact to (people), environment, (asset) and reputation.
