An Taisce v An Bord Pleanala

Factual and Procedural Background

This judgment concerns two judicial review applications challenging a planning permission granted by the respondent for the continued use and operation of a peat and biomass co-fired thermal power plant located in Clonbullogue, Co. Offaly. The first applicant, a longstanding non-governmental organisation, sought to quash the decision granting planning permission under reference PL19.242226 and to obtain declarations regarding the adequacy of environmental impact assessments related to peat extraction supplying the plant. The second applicant also sought judicial review challenging the planning permission on the grounds of alleged failures to comply with the Habitats Directive concerning conservation obligations related to peat extraction impacts on designated special areas of conservation.

The power plant was originally permitted in 1998, with subsequent permissions allowing changes in fuel use and biomass storage. The current permission extended the operation for ten years from 2013. The planning permission application was accompanied by an Environmental Impact Statement (EIS) and involved an environmental impact assessment (EIA) and screening under the Habitats Directive. The peat fuel is sourced from licensed bogs controlled by separate entities, which hold Environmental Protection Agency (EPA) licenses for peat extraction.

The applicants challenge the adequacy of the environmental assessments carried out by the respondent, particularly the exclusion of the environmental effects of peat extraction from the EIA and the failure to conduct an appropriate assessment under the Habitats Directive. The court was tasked with determining the legality of the planning permission and the scope of the respondent’s obligations under EU environmental directives as transposed into Irish law.

Legal Issues Presented

1. Whether the respondent was obliged under the Environmental Impact Assessment Directive (Directive 2011/92/EU) to include the environmental effects of peat extraction supplying the power plant within its environmental impact assessment before granting planning permission.
2. Whether the respondent failed to comply with the Habitats Directive (Directive 92/43/EEC) by not conducting an appropriate assessment of the effects of peat extraction on designated special areas of conservation.
3. Whether the respondent had a remedial obligation to address historical deficiencies in environmental assessments related to peat extraction licensed by the EPA.
4. The extent of the respondent’s jurisdiction and competence in assessing environmental effects related to separate sites supplying fuel for the power plant.
5. The adequacy and sufficiency of evidence presented by the second applicant to support claims under the Habitats Directive.

Arguments of the Parties

First Applicant's Arguments

• The environmental effects of extracting peat as a fuel source for the power plant were not properly assessed under the EIA Directive prior to the construction of the plant or in the current planning permission process.
• The respondent is under a remedial obligation to address prior deficiencies in environmental assessments relating to peat extraction before granting planning permission.
• The respondent’s environmental impact assessment was inadequate and failed to comply with the Directive’s broad scope and purpose.
• The indirect environmental effects of peat extraction supplying the power plant fall within the scope of the respondent’s assessment obligations.

Second Applicant's Arguments

• The respondent failed to comply with the Habitats Directive by not conducting an appropriate assessment of the peat extraction’s effects on Natura 2000 sites, specifically the River Barrow and River Nore SAC and the River Boyne SAC.
• The respondent and other state parties failed to establish necessary conservation measures and to avoid deterioration of habitats and disturbance of species in special areas of conservation.
• The development is likely to have significant effects on protected sites and should have been subject to appropriate assessment under Article 6 of the Habitats Directive.
• A screening assessment for appropriate assessment was required under national legislation.

Respondent and Notice Parties' Arguments

• The respondent’s jurisdiction is limited to the development site of the power plant and does not extend to separate peat extraction sites or EPA licensing regimes.
• The operation of the power plant is not contingent on sourcing peat from any particular bogs, and there is no condition restricting fuel sourcing.
• The remedial obligation to carry out an EIA cannot be exercised beyond the respondent’s sphere of competence and does not require assessment of separate peat extraction sites.
• The applicants’ arguments amount to impermissible project splitting, as peat extraction and power plant operation are separate projects on separate sites.
• The second applicant failed to provide sufficient evidence or expert analysis to support its claims under the Habitats Directive.
• Legal precedents establish that the respondent’s planning decision is subject to a reasonableness standard and was not shown to be unreasonable.

Court's Reasoning and Analysis

The court began by delineating the limits of its jurisdiction, emphasizing that it could only consider the planning permission for the power plant and not the legality of the EPA licenses or the peat extraction activities on separate sites. The court acknowledged that the peat extraction sites supplying the power plant are distinct from the power plant site and that the respondent’s jurisdiction is confined to the latter.

Regarding the first applicant’s claim, the court accepted that the Environmental Impact Assessment Directive has a broad scope and purpose, requiring assessment of direct and indirect environmental effects of a project. The court found that the peat extraction supplying the power plant constitutes an indirect environmental effect relevant to the assessment under Article 3 of the Directive as incorporated into Irish law.

The court held that the respondent erred in completely excluding consideration of the indirect environmental effects of peat extraction when granting planning permission. While the peat extraction sites are separate, the power plant relies on these as its major fuel source, establishing a functional link sufficient to require consideration of indirect effects within the EIA process.

However, the court rejected the first applicant’s argument that the respondent had a remedial obligation to address historical deficiencies in environmental assessments related to peat extraction licensed by the EPA, as this would exceed the respondent’s competence and jurisdiction.

Concerning the second applicant’s claims under the Habitats Directive, the court found that the applicant failed to meet the evidential burden required to establish an arguable case. The affidavit and supporting documents were insufficiently precise or cogent to demonstrate that the respondent failed in its obligations. The court relied on established jurisprudence requiring clear and particularized grounds in judicial review applications.

The court further considered relevant case law on project splitting and functional interdependence, concluding that the power plant and peat extraction are separate projects and that the respondent’s narrow interpretation of its assessment duties was incorrect but not unreasonable in the context of the evidence.

Ultimately, the court emphasized the need for decisions based on factual reality rather than theoretical constructs and underscored the importance of the respondent’s specialist planning function subject to judicial review on reasonableness grounds.

Holding and Implications

The court granted a declaration that where the environmental effects of extracting the peat fuel source for the thermal power plant were not properly assessed for the purposes of the Environmental Impact Assessment Directive, the respondent is obliged to ensure the effectiveness of the Directive by subjecting those environmental effects to Environmental Impact Assessment before granting planning permission for the thermal power plant.

The court refused to quash the planning permission or grant relief sought by the second applicant due to insufficient evidence and failure to meet procedural requirements.

The decision clarifies that indirect environmental effects from separate but functionally linked sites must be considered in environmental impact assessments under Irish law implementing EU directives. However, the court limited its intervention to the scope of the planning permission and did not extend jurisdiction to EPA licensing or peat extraction legality.

No new precedent was set beyond affirming the broad scope of environmental assessments and the limits of judicial review in this context. The direct effect is that future planning permissions involving fuel sourcing may require more comprehensive environmental assessments including indirect effects.
