1 Lynas Environmental Management

2 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 Recognition by peers and stakeholders Third Party Monitoring Regulatory Compliance Safety and Health at LAMP and the environment Self Regulation by Lynas Regulatory Monitoring

3 Lynas is compliant with its License Conditions FOSL TOL 1st (2 yrs) FOSL 2 nd (2 yrs) FOSL 3 rd FOSL (3 yrs) [50 major conditions] 78 EIA AC Conditions Routine audits and inspection by DOE/3 rd party EIA Routine audits inspections by AELB NOT under CIMAH regulations Routine inspection by DOSH OSH others MBK, MOH etc Inspections

4 Safety, Health and Environmental Management Lynas implements TWO Environmental Management Systems: RADIOLOGICAL and NON-RADIOLOGICAL 4

5 Radiation Safety and Health Management (RSHM) at LAMP RSHM is an integral and important part of the overall SHES Systems at the LAMP Radiation Safety and Health Radiation Protection Program (adopts RSMS and OHSAS 18001) 1. Occupational exposure 2. AMS AELB FOSL conditions Public and environmental exposure and impact Carried out by 3 rd party AELB regulatory Monitoring and Audit

6 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 3 rd 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: To date Lynas carried out 43 environmental and occupational monitoring

7 Monitoring is carried out independently by the regulators and 3 rd party and Lynas Monitoring Programs - environment Environmental: 3 rd 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 Monitoring Monitoring frequency Vendor Monitoring, YTD (Jan,2010,2018) Ambient air Monthly PERMULAB 91 Balok River Monthly PERMULAB 91 Groundwater Monthly PERMULAB 91 Noise level Monthly PERMULAB 91 Stack sampling Half- yearly PERMULAB 17 Final Discharge Point Daily Weekly ESM 2, (starts 2011) Storm Retention Pond Daily Weekly ESM 2, (starts 2011) Sewerage Treatment Plant Weekly ESM 342 (starts 2012)
