WQ.330/2024

WRITTEN QUESTION TO THE MINISTER FOR INFRASTRUCTURE

BY DEPUTY J. RENOUF OF ST. BRELADE

QUESTION SUBMITTED ON MONDAY 7th OCTOBER 2024 ANSWER TO BE TABLED ON MONDAY 14th OCTOBER 2024

Question

"With reference to La Collette Waste Management Site, will the Minister advise when it is estimated each of the inert and hazardous waste operations on the site will reach full capacity; and will he detail what plans, if any, are in place for when full capacity in either has been reached?"

Answer Inert Waste

Based on the rate at which inert waste has been received over the last 12 months, the Inert Waste Reception will be at capacity in 8 months. This is based on the immediately available capacity of the West Mound' as proposed under planning application P/2023/1070. Inert waste could be temporarily stockpiled in the West Mound up to a maximum height of 20m as permitted under approved planning application P/2104/1706. This would provide capacity for a further 23 months, if required.

Additional capacity is achieved in other areas of the site and super-fill landforms under the proposals made in planning application P/2023/1070. However, changes to the site layout and infrastructure are required in order for this to be available. It must be noted that approval of planning application P/2023/1070 is awaiting finalisation of planning conditions.

The Infrastructure and Environment Department has recently completed a procurement process for future inert waste management at La Collette. The chosen solution will aim to recycle 100% of waste received with waste disposed' of at the site only as a last resort. This will significantly extend the life of the Inert Waste Reception at La Collette. The contract for this solution will be in place by December 2024.

Hazardous Waste

Based on the rate at which hazardous waste has been received over the last 10 years, and assuming current practices continue, the Hazardous Waste Reception will be at capacity in 10 years. This is based on the additional capacity achieved by increasing the height of the East Headland' as proposed under planning application P/2023/1070. Currently, ash and residues from the Energy Recovery Facility are exported for recovery. Ash and residues from the Animal Carcass Incinerator and Clinical Waste Incinerator, asbestos containing materials, and contaminated soils are disposed of at La Collette.

In the short term, in order to extend the life of the Hazardous Waste Reception, the Department will work with Regulation to drive minimisation of contaminated soils by design and remediation through the planning process. The Department will also explore future solutions for hazardous waste management, including export for recovery and development of other areas of La Collette or other sites, in order to identify a long-term solution. If this solution involves other areas of La Collette or other sites, the Department will seek to establish these in future Island Plans.
