QUESTION NO.14

QUESTION: Councillor A. Hayes

To ask the Manager to provide a comprehensive list of all historic landfills within the areas of this combined ACM to include but not limited to: - Locations - Whether on the national register or not - Which of them have certificate of authorisation applications submitted to the EPA and what retrospective control measures have been introduced - Has landfill leachate been identified in any location - Has SDCC the resources it needs to to take remedial action at these sites

REPLY:

A national list of historical landfill sites is maintained by the National Waste Collection Permit Office.  The National Waste Management Plan for a Circular Economy 2024-2030, provides a standardised approach for local authorities to address the issues associated with historic landfill sites. The plan takes into consideration the Waste Management (Certification of Historic Unlicensed Recovery and Disposal Activity) Regulations 2008, where a local authority must undertake an environmental risk assessment (ERA) of their Closed Landfills (in accordance with the EPA Code of Practice), identify any required remediation works and subsequently apply to the EPA for a Certificate of Authorisation (CoA). SDCC is committed to the plan and in doing so are working closely with are colleagues in the Eastern-Midland Regional Waste Management Planning Office.

The historic landfill sites are recorded under the following headings.

Closed Landfill Sites (Section 22) - landfill site operated by a local authority for the recovery or disposal of waste without a waste licence on any date between 15th July 1977 and 27th March 1997.

• Waterstown, Palmerstown, Dublin 20 is the only site described as a Closed Landfill listed in the Lucan / Palmerstown / North Clondalkin Area. A retrospective certificate of authorisation (H0424-01) is being processed by the EPA. As part of the process, a Tier 3 assessment has been undertaken of the site to establish the level of risk and appropriate monitoring. The works are subject to EPA approval and reporting.

 Pre 1977 Landfill - landfill site operated for the recovery or disposal of waste prior to 15th July 1977.

• There are no sites listed in the Lucan / Palmerstown / North Clondalkin Area

Delivery of the remediation work is coordinated through the Regional Waste Management Planning Offices. Project plans are in place for necessary ground water monitoring.  The plans will be constantly reviewed and amended as required subject to the monitoring findings.
