Strategy and Targets for Spill Management

Zero spill is one of SSHE Target Zero which is part of the Company annual SSHE KPIs. To achieve the target, PTTEP focuses on efficient incident management, by forecasting spill scenarios and preparing responses. PTTEP follows the principles of Spill Management Plan in responding to spills. The system helps establish the organizational structure and the response process, including documentation, equipment, and resources.

PTTEP's spill management plan is regularly updated and follows the Tier 3 Spill response system defined by the International Petroleum Industry Environmental Conservation Association (IPIECA) and International Association of Oil and Gas Producers (IOGP). The response system is as follows:

• Tier 1: Spills that require Asset capability and resources.
• Tier 2: Spills that require local and national resources, such as Subdistrict Administration Organization, Department of Disaster Prevention and Mitigation, Marine Department, and Royal Thai Navy.
• Tier 3: Spills that require global and international response resources, such as Oil Spill Response Limited (OSRL), in collaboration with Tier 2 resources.

Spill Risk Management

PTTEP manages the spill risk in compliance with laws/regulations and company risk management process for all E&P activities in order to ensure the potential risk from spill has been assessed and mitigated to "As Low As Reasonably Practicable or ALARP" level. For an effective spill management, those risks are audited and reviewed regularly.

Furthermore, the Company prepared the spill management plan and constantly conducted emergency drills at a corporate- and project-level. This is to assess its preparedness and capability, as well as continuously improved the management plan. The Company has entered into agreements with response organizations in national and international levels, for prompt and appropriate management. The organizations include the Oil Industry Environmental Safety Group Association (IESG), the Petroleum Industry of Malaysia Mutual Aid Group (PIMMAG), and the Oil Spill Response Limited (OSRL). PTTEP, as a corporate member of IESG, provides supports to reinforce Thailand's spill management system. Such supports include participation in equipment test and annual drill as well as serving as a member in various committees.

PTTEP conducts the spill capability assessment for both existing and new projects, to prepare response approaches. PTTEP also focuses on spill management trainings for all related parties.
