Polskie LNG S.A.

1) Identification of the operator and address of the facility

Liquefied natural gas regasification terminal in Świnoujście, hereinafter the LNG Terminal, is operated by Gaz-System S.A - Mszczonowska 4, 02-337 Warszawa, Mazowieckie province.

LNG Terminal address: Ku Morzu 1, 72-602 Świnoujście.

2) Identification of the person providing the information by stating the person’s position The person providing the information is the Director of the LNG Terminal Division.

3) Statement that the establishment is subject to the provisions on High Risk Facilities (ZDR) and that the Provincial Headquarters of the State Fire Service (KW PSP) received the ZDR notification

The LNG terminal is a complex of interconnected process installations, equipment and structures used for:

receiving liquefied natural gas (LNG) from LNG ships (methane carriers), LNG storage,

regasification of stored LNG and supply of natural gas to the gas transmission network, loading LNG into tanker trucks.

The LNG Terminal, due to the amount of LNG and natural gas contained in the process storage tanks and process installations, is subject to the legal provisions applicable to high risk facilities (ZDR).

Notification of the LNG Terminal as ZDR to the Provincial Headquarters of the State Fire Service and Provincial Environmental Protection Inspectorate in Szczecin was submitted on 4.11.2013.

In accordance with the ZDR regulations, the following have been developed and implemented at the LNG Terminal:

Failure Prevention Program,

Safety Report, which proves that the LNG Terminal fulfils the applicable safety standards and the multi-layered technical safeguards systems in place as well as procedural and organisational safety management system measures ensure that they are capable of preventing and limiting the

consequences of potential failures to an acceptable risk level.

Internal Operational and Rescue Plan describing rescue procedures to ensure readiness of the LNG Terminal to undertake rescue operations in case of emergency or failure.

These documents were, in accordance with the law, adopted and/or approved by the West Pomeranian Provincial Inspector of Environmental Protection and the West Pomeranian Provincial Chief of State Fire Service.

4) Description of the measures applied and the procedures to be followed in the event of an industrial accident

Good engineering practices

are based on global standards used in the design, construction and operation of LNG Terminals.

Mechanical and structural integrity

(2)

the adopted quality assurance programs, including adherence to global design standards, material specifications as well as manufacturing and construction procedures, guarantee conformity of the LNG Terminal with global standards,

LNG tanks in full safety casing, outer concrete containment tank is capable to contain the stored LNG in case of failure of the internal steel tank,

monitoring of equipment operational parameters and conformity with design limit values, as well as protection systems against exceeding design limit values,

pressure build-up protection systems, used for the safe evacuation of LNG and gas streams in the event of an overpressure or fire.

Multi-stage protection system

if the first stage of protection in a specific point of the technological process fails, then the next stage is initiated to stop escalation of the failure risk,

Safety management system

ensures that the operation and management of the LNG Terminal complies with the regulations and best practices of global LNG terminals,

the safety management system at the LNG Terminal is covered by the Integrated Management System based on ISO 9001, 14001, 18001,

recording and analysis of potentially hazardous events and emergency situations,

routine assessment of process risk management to ensure the level of risk acceptable to people, the environment and property in the operation of the LNG Terminal.

Safe system of work

selection of personnel with appropriate safety competences,

a permit to work system, permits issued by authorised persons, to ensure that work is safe for people, property and the environment,

proper supervision of conformity with organisational and procedural regulations as well as occupational safety.

Security

LNG Terminal’s area surveillance systems against unauthorised intrusion,

monitoring the movement of people and materials at the gates and within the LNG Terminal site, a specialist armed formation responsible for the physical protection of the LNG Terminal.

Fire protection strategy

direct protection - safe distances, fire resistant materials,

passive fire protection - protection with fireproof coating, water spraying, preventing collapse of structures or equipment supports exposed to prolonged fire,

integrated fire safety management system - used to detect hazards caused by gas leakage or low temperature (LNG), fire, fulfilling the functional and safety requirements through alarming, automatic activation of the system to cut off the endangered zone, shutting down the installation and activation of rescue and firefighting systems,

the emergency shutdown system logic is implemented by an ESD system which is independent of the primary process control system,

collecting emergency LNG spills into retention basins with a foaming system to reduce LNG vaporization and safely disperse LNG vapours,

emergency electrical supply - diesel generators to provide reliable electrical power for safety systems.

Rescue operations:

(3)

Rescue operations to protect people, environment and property from the effects of an industrial accident are defined in the Internal Operational and Rescue Plan, with the use of:

two fire-fighting water systems - a fresh water fire-fighting network with a water tank, capacity of 1700m3, and a seawater fire-fighting network, each with duplicated pumps and standpipes,

controllable water and foam cannons for structure cooling or fire fighting, water curtains to limit the spread of LNG and gas vapours,

water spraying systems for equipment exposed to fire, foam generators to cover LNG spills,

fixed fire-fighting systems in buildings, portable fire fighting equipment,

a system for alarming and broadcasting voice messages about the threat.

Initial rescue operations and evacuation of personnel in the event of an emergency are carried out by trained LNG Terminal personnel in accordance with the Internal Operational and Rescue Plan. If necessary, rescue and firefighting operations are taken over by the State Fire Service.
