Shire of Wyndham East Kimberley
Landfill Closure Management Plan – Kununurra Waste Disposal Facility (2025)
Preparation of a comprehensive landfill closure management plan to support regulatory compliance and long‑term environmental protection at the Kununurra Waste Disposal Facility
Development of final landform, capping, revegetation, surface water and landfill gas management concepts based on a detailed risk assessment
Definition of post‑closure monitoring and maintenance requirements for groundwater, landfill gas, surface water and cap integrity over the aftercare period
Preparation of closure and post‑closure cost estimates to assist the Shire with budgeting for future rehabilitation and monitoring liabilities
ASK Waste Management was engaged by the Shire of Wyndham East Kimberley to prepare an updated Landfill Closure Management Plan (LCMP) for the Kununurra Waste Disposal Facility. The LCMP provides a comprehensive, risk‑based framework for the progressive rehabilitation, final closure and post‑closure management of the landfill, in accordance with Western Australian regulatory requirements and best‑practice landfill guidelines.
The plan documents the environmental setting of the site, assesses risks to sensitive receptors, and establishes a technically robust rehabilitation design including final landform contours, capping system, surface water controls and landfill gas management.
It also defines post‑closure monitoring and maintenance requirements over a long‑term aftercare period, together with detailed cost estimates to support financial planning for closure liabilities.
The LCMP is intended to support licence compliance, inform operational decision‑making during the remaining life of the facility, and provide assurance that long‑term environmental risks are appropriately managed.
