1. 1 Management of Mercury containing Wastes from Oil and Gas Operation in Indonesia Rasio Ridho Sani Director of Bureau for Planning and International Cooperation Ministry of the Environment Republic of Indonesia

2.  Mercury is classified as hazardous substance with limited use  Mercury containing waste classified as hazardous waste  Hazardous waste management requires special license  Prohibition to import hazardous wastes to the Country

3.  Some of gas reservoirs in Indonesia contain mercury  Gas field operation can produce waste containing mercury  Elemental mercury could be produced as by product  There are no mercury recovery facilities in Indonesia: generators are responsible for their waste management

5. Mercury wastes from Oil & Gas Operations Spent Catalyst Adsorbent Sulphur Imprenated Activated Carbon Sludge Crude oil extraction and processing Natural gas extraction and processing Elemental Mercury Mercury Removal treatment Mercury Removal treatment Air Water Land Potential releases

6. Amount of Waste (kg/year) Mercury Concentration (ppm) Total Hg/year (kg) Sources Elemental Mercury **) 684 Pure684Gas Field Spent Catalyst 0.052300 – 70015.6 -36.4Gas Field Activated Carbon 0.024< 50.12LNG Sludge0.01< 50.05LNG *) Amount of mercury produced vary from one to other reservoir **) Elemental mercury based on data : Nov 1991- Dec 1995 = 85 kg/month Jan 1996-July 1997 = 29 kg/month

7. Mercury Removal Temporary Storage Waste Transport Landfill Waste Treatment Plant Mercury Waste Management Practices As there are no mercury recovery facilities in the country, spent catalyst exported to the other countries Elemental Mercury as a by product : Laboratory and research Previously: sent to Chlor Alkali Industry

8. Temporary Storage of Waste Containing Mercury  Special technical guidelines for hazardous waste temporary storage  Licensing system for hazardous wastes temporary storage  Compliance and monitoring inspection program  Special technical guidelines for hazardous waste temporary storage  Licensing system for hazardous wastes temporary storage  Compliance and monitoring inspection program

9. Enhancing mercury management policy Establishment of Roundtable Policy Dialog Health Sector Oil & Gas Sector Mining & Energy Sector Mercury Waste Temporary Storage (Producer) No Landfill for Hg Mercury Recovery Surplus Mercury Storage Surplus Mercury Storage

10. IV. Conclusion Oil and Gas Industry is a source of by-product elemental mercury and mercury containing waste Temporary storage is feasible with certain technical requirements Mercury waste management should be part of the national hazardous waste management plan Extended producer’s responsibility is central to Indonesia’s approach in the management of surplus mercury both as potential commodity and as waste Common responsibility and cooperation among stakeholders is imperative for mercury management.
