Factual and Procedural Background
This case concerns an illegal landfill site located in The State, adjacent to a river and partly within a candidate Special Area of Conservation (cSAC). The landfill was used for illegal dumping by multiple parties, including a local authority, between 1979 and 2001. Following closure of the site, the local authority initially sought remediation by other polluters but later undertook a partial remediation itself, spending significantly less than originally estimated and leaving the majority of waste in situ. The primary legal questions relate to the adequacy of this remediation, compliance with environmental law and licensing requirements, and whether further orders for remediation are necessary.
Procedurally, this is the eighth judgment in a series of High Court proceedings involving the local authority, the company owning the site, and other parties, including the Environmental Protection Agency (EPA) as a notice party. The proceedings have involved multiple phases and interlocutory applications, including joinder and striking out of parties. The current judgment addresses Module II of the proceedings, focusing on the adequacy of the remediation and related environmental and licensing issues.
Legal Issues Presented
- Did the remediation comply with the EPA Code of Practice and ministerial circulars?
- Apart from direct contact with groundwater, did the remediation comply with the European Communities Environmental Objectives (Groundwater) Regulations 2010 and the EPA Report on Groundwater Discharges?
- Is there a current environmental risk arising from waste on the site?
- Is the local authority disposing of waste by means of long-term storage without a licence?
- Should an order for remediation be made?
Arguments of the Parties
Appellant's Arguments
- The local authority contends that the remediation carried out significantly improved the site and that further investigation or more limited remediation might be appropriate.
- It argues that the EPA Code of Practice was applied or that certain parts did not apply due to emergency powers invoked under statute.
- The local authority submits that any remaining risk is speculative or de minimis and that a proportionate response is required.
- It suggests that the long-term holding of waste may not yet require a licence or that the EPA should be consulted further before imposing further orders.
- The local authority emphasizes cost and practicality concerns, advocating for the least onerous order possible.
Appellee's Arguments
- The company owning the site and other parties argue that the remediation was inadequate, leaving the vast majority of waste and environmental risk in place.
- They submit that the EPA Code of Practice and EU environmental law require full removal of non-inert waste, particularly given the site's sensitive location adjacent to a cSAC and a river used for drinking water and important fish habitats.
- They assert that the local authority's approach was flawed, policy-driven, and failed to apply the precautionary principle.
- They maintain that the local authority's possession of the site has become long-term storage requiring a licence, which has not been obtained.
- They seek a mandatory order requiring full removal of all waste and contaminated materials to an approved facility, with appropriate landscaping and restoration before returning possession.
Notice Party (Environmental Protection Agency) Position
- The EPA participated as a notice party but did not actively challenge the findings of the prior judgment and did not make substantive submissions in the resumed proceedings.
- The EPA was involved in a Technical Working Group during remediation but its role and statements regarding compliance with its own code were questioned by the court.

Court's Reasoning and Analysis
The court undertook a detailed examination of the factual and expert evidence, focusing on the nature and extent of the waste, the hydrogeological characteristics of the site, and the remediation efforts undertaken by the local authority. It found that the site is highly sensitive due to its proximity to a cSAC, a river used for drinking water and fish spawning, and vulnerable aquifers in hydraulic continuity with the waste.
The court identified multiple breaches of the EPA Code of Practice, ministerial directions, and EU environmental law, including the Waste Framework Directive, Landfill Directive, and Water Framework Directive. It concluded that the local authority's remediation was fundamentally flawed, being policy- and cost-driven rather than science-led, with a predetermined decision to leave as much waste as possible in situ prior to risk assessment. This approach contravened the presumption in the Code of Practice that waste should be removed unless an alternative provides greater environmental protection.
The court found that hazardous and non-inert waste remains on site, including asbestos and waste in contact with groundwater, creating a current environmental risk. The local authority's possession of the site has become long-term storage without a licence, contravening statutory licensing requirements. The EPA's involvement in the Technical Working Group and its subsequent assertions of compliance with its own code were found to be misleading and potentially compromising.
Applying established legal principles, including the precautionary principle, the polluter pays principle, and the requirement for effective enforcement of EU law, the court rejected the local authority's arguments for limited or no further remediation. It emphasized that the risk, even if not currently manifesting in the river, is sufficient to warrant remedial action.
The court also considered proportionality and discretion, concluding that these do not permit a lesser remedy given the scale of the illegal dumping, the environmental sensitivity, and the local authority's role as a polluter. The court rejected the notion that cost or complexity should excuse non-compliance or partial remediation.
Finally, the court addressed procedural and evidentiary issues, including the need to manage further proceedings and the involvement of the EPA, concluding that further investigation or referral to the EPA would be inappropriate at this stage given the extensive evidence already before the court.
Holding and Implications
The court ordered the local authority to remove all waste and contaminated materials from the site to a licensed disposal facility, properly fill and landscape the site with inert material sourced externally, and return possession of the site to the company owning it by a specified date.
The court directed that the hearing proceed immediately to Module III to address remaining issues concerning the precise terms of the order and costs. It required the parties to prepare initial draft timetables for the remediation works, including consideration of environmental impact assessment, licensing, and engagement of contractors.
The implications of this decision are primarily the imposition of a mandatory remediation obligation on the local authority as a polluter and long-term holder of waste, enforcing compliance with EU and national environmental law. No new precedent was set beyond the application of established principles of environmental protection, precaution, and effective enforcement. The decision underscores the court’s commitment to uphold environmental law rigorously, particularly in cases involving illegal dumping and sensitive ecological sites.
