Discussion Legal Overview Government Regulation No. 17 year 1974 governs decommissioning In Indonesia, pre 1994, PSC only provides simple and unclear wording for decommissioning, as follows : “Contractor shall be responsible for the preparation and the execution of the work program, which shall be implemented in a workmanlike manner and by appropriate scientific methods, and contractor shall take the necessary precaution for the protection of navigations and fishing and shall prevent extensive pollution of the seas and rivers. It is also understood that execution of the work program shall be exercised so as not to conflict with the obligations imposed on the government of Indonesia by International law” Post 1994 PSC started setting out clauses on how to manage the execution and cost for decommissioning : “ Contractor shall, after the contract expiration or termination, or relinquishment of part of the contract area, or abandonment of any field, remove all equipment and installation ………………………………” “Contractor shall include in annual budget of operating cost, estimate of the anticipated abandonment and site restoration cost…………….” “ Contractor shall include with requisite plan of development for each commercial discovery, an abandonment and site restoration………………………” 24/02/2019

Discussion Issues in Pre 1994 PSC (copied from presentation of Rudi Simamora of CNOOC) 1/2 Who should be responsible for undertaking the decommissioning and to bear the cost incured thereof ? BPMIGAS views that decommissioning is the responsibility of contractor under petroleum operation scheme as set out in PSC. Contractors view that decommissioning is the responsibility of BPMIGAS based on the followings : BPMIGAS holds the title to the equipments purchased under work program Definition of work program doesn’t include post operation activities i.e decommissioning GR No. 17/1974 prescibes that Pertamina or company having working relationship with Pertamina, which is responsible for the management thereof, shall be responsible for decommissioning GR No. 17/1974 brought no change in terms of managing decommissioning matters The sacntity of contract as guaranteed by Law No. 22/2001 24/02/2019

Discussion Issues in Pre 1994 PSC (copied from presentation of Rudi Simamora of CNOOC) 2/3 Should the facilities to be removed totally or should it remain in place, wholly or totally, perhaps to serve another purpose Geneve convention 1958 prescribes a rule of total removal UNCLOS 1982 envisage partial removal IMO removal standards, 1989 allows partial removal The London Convention on Prevention of Marine Pollution by dumping of Wastes and Other Matter , 1972 allows partial removal Indonesia has ratified the Geneva Convention 1958 and UNCLOS 1982 GR No. 17/1974 requires total removal 24/02/2019
