Take from the ground, give back with proof.

Phase 1: Pit location and power source are locked in here.

Forest boundaries, pit location and the choice of power plant are the costliest decisions in a mine's life. Baselines recorded now become the reference for reclamation and PROPER until closure.

What needs to be ready

1. • 1.1

     1.1 Forest area and spatial status

     Map forest functions and spatial approval (KKPR) inside the licence area (WIUP), then estimate the forest-use levy before drilling.

     According to Forestry Ministry Regulation 14/2025

     • Environmental permits
     • Biodiv+
   • 1.2

     1.2 Nature and village baseline

     Survey flora, fauna, rivers and surrounding villages before any disturbance, and run FPIC where customary land is involved.

     • Biodiversity
     • Biodiv+
   • 1.3

     1.3 Energy and carbon scenarios

     Calculate tCO₂ per tonne of product for each supply option: captive coal, the PLN grid or renewables.

     • Carbon+

Phase 2: One set of figures for permits, guarantees and lenders.

The AMDAL, technical approvals, reclamation plan and community development plan all cite the same design figures. Lenders using IFC standards read them too, so it pays to calculate them once, properly.

What needs to be ready

1. • 2.1

     2.1 AMDAL unit by unit

     Cover the pit, waste dump, settling ponds, smelter, power plant and jetty in one AMDAL, with pond design based on acid-forming rock tests.

     According to Government Regulation 22/2021

     • Environmental permits
     • PROPER+
   • 2.2

     2.2 Reclamation plan and guarantee

     File the reclamation plan as soon as the mining business licence (IUP) is issued; the first five years' guarantee is placed in full once the plan is approved.

     According to Energy Ministry Decree 344.K/MB.01/MEM.B/2025

     • Nature-based solutions
     • Biodiv+
   • 2.3

     2.3 Community development master plan

     Build the mandatory community development programme (PPM) with local government and residents, using indicators that can later be measured as SROI.

     According to Energy Ministry Decree 1824 K/30/MEM/2018

     • Community development
     • Social+

Phase 3: Settling ponds first, land clearing second.

Sediment, dust and community complaints peak during construction. Topsoil stored properly today decides what reclamation costs years from now.

What needs to be ready

1. • 3.1

     3.1 Settling ponds before clearing

     Build ponds and perimeter drains first, then record downstream river quality from day one.

     • Water audit
     • IoT
   • 3.2

     3.2 Topsoil and staged clearing

     Clear land in line with the annual work plan, stockpile topsoil separately and plant cover crops on the piles.

     • Nature-based solutions
     • Biodiv+
   • 3.3

     3.3 Contractors and community grievances

     Set safety, wage and housing standards for contractors from the day the contract is signed, and open a grievance channel before heavy equipment arrives.

     According to IFC Performance Standard 2

     • Social impact
     • Social+

Phase 4: Your baseline year is set before commercial production.

Emissions intensity, wastewater load and energy use in later years will all be compared against this one. Meters and online monitors installed early make those figures auditable.

What needs to be ready

1. • 4.1

     4.1 Online monitoring and the operating certificate

     Install continuous emission monitoring (CEMS) on stacks and online wastewater monitoring (SPARING) at the mine outlet, then obtain the operating certificate (SLO) before the trial ends.

     According to Environment and Forestry Ministry Regulations 5/2021 and P.80/2019

     • Emission & methane monitoring
     • IoT
   • 4.2

     4.2 GHG baseline and energy manager

     Build the base-year Scope 1, 2 and 3 inventory, and appoint a certified energy manager if the smelter uses 4,000 TOE or more a year.

     According to Government Regulation 33/2023

     • GHG accounting
     • Carbon+
   • 4.3

     4.3 PROPER and reclamation reporting

     Prepare your first environmental monitoring report (RKL-RPL), evidence of land damage control and the annual reclamation report due on 31 January.

     According to Environment Ministry Regulation 7/2025 and Energy Ministry Decree 344.K/MB.01/MEM.B/2025

     • PROPER
     • PROPER+

Phase 5: Proof of efficiency lifts your rating and lowers your costs.

Green and Gold PROPER ratings demand evidence of energy, water and waste efficiency, along with community programmes you can measure. Ferronickel buyers, lenders and investors read the same figures.

What needs to be ready

1. • 5.1

     5.1 From Green towards Gold

     Build evidence on LCA, energy and water efficiency, waste 3R, biodiversity and SROI for community programmes.

   • 5.2

     5.2 Slag and coal ash as raw material

     Nickel slag and fly and bottom ash (FABA) from non-stoker power plants are listed as non-hazardous waste, so they can become construction materials under your environmental approval.

   • 5.3

     5.3 Emissions per tonne for CBAM and PSPK

Phase 6: The mine closes; the land keeps its value.

Recovered land can become forest, farmland or a solar plant, and the licence area can only be returned once reclamation is judged successful. The post-mining guarantee must be fully placed two years before the production licence expires.
