Lynas Environmental Management

Lynas Occupational and Environmental Safety and Health Management Systems

• Hazards and risks regulated

primarily by the AELB, DOE and DOSH

• Management involves hazards

identification, Risks assessment, Risks Control and Continuous Improvements

• Management involves:

– Regulatory control through license conditions – Regulators audits and inspections – Third party audit and monitoring – Self-regulations – Recognition by peers, stakeholders and independent parties

Safety and Health at LAMP and the environment

Regulatory Compliance Regulatory Monitoring Self Regulation by Lynas Third Party Monitoring Recognition by peers and stakeholders

Lynas is compliant with its License Conditions

Lynas implements TWO Environmental Management Systems: RADIOLOGICAL and NON-RADIOLOGICAL

Safety, Health and Environmental Management

Radiation Safety and Health Management (RSHM) at LAMP

Radiation Safety and Health Radiation Protection Program (adopts RSMS and OHSAS 18001) AELB regulatory Monitoring and Audit AELB FOSL conditions

RSHM is an integral and important part of the

• 2. AMS

Public and environmental exposure and impact Carried out by 3rd party

Monitoring Programs - radiation

• Radiation:

– 4 types of monitoring programs by Lynas: a) Occupational Exposure Monitoring Program, b) Environmental Radiation Monitoring Program, c) Aerosol Monitoring System and d) AELB monitoring – Lynas monitoring is carried out by 3rd party consultant accredited by the AELB up to 20 km – Real time and online monitoring using AMS located at LAMP and Kuantan – AELB independent monitoring – Lynas self regulatory monitoring – Data available on line, and reported routinely. (The web address is: https://175.142.36.205/public/map/) – To date Lynas carried out 43 environmental and

• ccupational monitoring

Monitoring is carried out independently by the regulators and 3rd party and Lynas Monitoring Programs

• environment

– 3rd party audit and inspection approved by DOE – DOE routine regulatory inspection – Lynas carries out it own monitoring and inspections – Data presented on-line and display on digital board located at gate 1 for public to view

RADIATION PERFORMANCE

43 monitoring from December 2012 – March 2018 showed

NO radiological impact to public and environment

Permissible Limit for public = 1 mSv per year; Permissible Limit for radiation workers = 20 mSv per year
