Ministerial Regulation of Energy and Mineral Resources (PerMen ESDM) No. 15/2018 and PTK-040 (PTK–040 /SKKMA0000/2018/S0) rev-1, which serve as the recent abandonment and site restoration (ASR) legal basis, mandated Oil and Gas upstream activity to perform EBA (Environmental Based Assessment) prior to or at the contract expiration date, or end-of-contract (EOC). The result of EBA which leads to ASR planning and activities, includes well plug & abandonment (P&A), facility decommissioning, and site restoration activities. The purpose of site restoration is to eliminate environmental risks by performing clean-up of the identified impacted sites from upstream exploitation and production operation activities. Onshore site restoration activities, as part of ASR, refers to several technical regulatory references. They include Ministerial Regulation of Environment (PerMenLH) No. 33/2009 concerning step-by-step Site Restoration Activity (site clearing, delineation, excavation, sampling, segregation, treatment), Governmental Regulation (PP) No. 101/2014 Attachment V. concerning reference of target analyte parameter and criteria, and Ministerial Decree of Environment (KepMenLH) No. 128/2003 on treatment method. This paper intends to provide information, which include overview, and lessons learned from onshore site restoration, as part of ASR activities, to stakeholders who may be subject to ASR implementation.
