Hockley v Essex County Council

Factual and Procedural Background

This claim for judicial review challenges planning permission granted by the Defendant, Essex County Council ("the County Council"), in June 2012 for a waste transfer station on a site in Great Dunmow. The application was made by the County Council itself as waste disposal authority. The Plaintiffs, Mr. and Mrs. Hockley, live near the site and objected to the proposal, contending that it should have undergone an environmental impact assessment ("EIA") and that the County Council misapplied relevant policy in the development plan. The interested party, Uttlesford District Council ("the District Council"), took no part in the proceedings.

Permission to apply for judicial review was granted on 28 January 2013 and the claim was joined with a previous judicial review concerning planning permission granted in March 2010 for a resource management centre on land including the site in question. That earlier permission was quashed following the County Council's submission to judgment in February 2013.

The Plaintiffs pursued two grounds in this claim: (1) whether the County Council erred in law in its approach to screening the development under the EIA regime, and (2) whether the decision to grant planning permission as a departure from Policy GD8 of the Uttlesford Local Plan was unlawful.

The site is 0.84 hectares located at Chelmsford Road south of the town, adjacent to residential properties, an ambulance station, a hotel, and an industrial estate. The land was formerly farmland and is part of an area allocated in the Uttlesford Local Plan 2005 for a civic amenity site and depot under Policy GD8.

The County Council had previously granted planning permission in 2010 for a resource management centre including a recycling centre and waste transfer/bulking station, but abandoned the recycling centre element in September 2010 and submitted a new application for the waste transfer station now challenged.

The waste transfer station proposed a capacity of 29,400 tonnes per annum of municipal and trade waste, with waste handling activities contained within a building and operating hours limited to weekdays and Saturdays. The County Council’s Development and Regulation Committee considered the application in June 2012 and was advised that the proposal formed part of an integrated waste management network in Essex.

The planning permission granted in June 2012 included conditions limiting throughput, operating hours, noise mitigation, and access improvements.

Legal Issues Presented

1. Whether the Defendant erred in law in its approach to screening the development under the Environmental Impact Assessment ("EIA") regime (ground 1).
2. Whether the decision to grant planning permission as a departure from Policy GD8 of the Uttlesford Local Plan was unlawful (ground 5).

Arguments of the Parties

Appellant's Arguments

• The standard of review for the EIA screening process should be more stringent than the conventional Wednesbury standard, especially given potential human rights implications.
• The County Council applied an unduly restrictive approach to assessing whether the development was likely to have significant environmental effects, failing to conduct a comprehensive assessment consistent with the precautionary approach required by the EIA directive.
• The County Council failed to take into account relevant cumulative effects and engaged in "project splitting" by not considering the development together with other local developments and future highway improvements, which could result in significant environmental impacts.
• Lang J.'s judgment in Mackman supports the argument that cumulative effects must be considered in screening decisions.
• Regarding Policy GD8, the County Council did not provide adequate or rational reasons for the departure from the policy, and the use of the site as a waste transfer station is fundamentally different from a civic amenity site.
• The departure from Policy GD8 was not marginal but fundamental, and the prior consent to judgment in earlier proceedings does not justify the current permission.

Appellee's Arguments

• The conventional Wednesbury standard applies to the screening opinion, and the court should only intervene if the decision was irrational or the screening opinion was defective in approach or reasoning.
• The County Council's screening opinion was lawful and supported by sufficient information provided by AMEC, including noise, transport, and odour assessments.
• The County Council correctly took the throughput as 29,400 tonnes per annum and reasonably concluded no significant environmental effects were likely.
• The screening opinion properly considered cumulative effects only with respect to "existing or approved" developments; at the time of screening, the other developments cited by the Plaintiffs were neither existing nor approved.
• The allegation of project splitting was misconceived as the waste transfer station is a standalone project independent of other developments or highway improvements.
• Lang J.'s decision in Mackman does not support the Plaintiffs' claim that the County Council's screening opinion was unlawful for failing to consider cumulative effects.
• Regarding Policy GD8, the County Council did not misinterpret the policy; the waste transfer station was reasonably described as "akin" to the civic amenity site use, and the departure was properly acknowledged and considered in the planning balance.
• The decision to grant planning permission was lawful and not inconsistent with the County Council's prior submission to judgment in earlier proceedings, which concerned a different statutory requirement.

Court's Reasoning and Analysis

The court undertook a detailed review of the EIA screening process applied by the Defendant. It found that the County Council correctly identified the development as Schedule 2 development under the 2011 EIA regulations and appropriately applied the thresholds and criteria, including the size of the site and proximity to controlled waters. The screening opinion was structured logically, addressed the relevant environmental considerations of discharges, emissions, and odour, and was informed by comprehensive documentation submitted by AMEC.

The court rejected the argument that the throughput should be doubled to account for waste entering and leaving the site, confirming that throughput refers to the quantity passing through the facility.

On cumulative effects and project splitting, the court held that the screening decision-maker must consider the project in its entirety and any other developments likely to cause significant effects. However, the waste transfer station was a standalone project, not part of a larger scheme, and no evidence demonstrated significant cumulative effects with other developments, many of which were not yet existing or approved at the time of screening.

The court accepted the County Council's approach that only existing or approved developments were relevant for cumulative consideration, consistent with government guidance. The possibility of future highway improvements and the development of the remainder of the allocated site as a civic amenity site were not sufficiently concrete to be included in the screening exercise.

Regarding the departure from Policy GD8, the court found no error in the County Council's interpretation or application of the policy. The officer's report clearly acknowledged the departure, assessed the proposal on its merits, and provided rational and adequate reasons for granting planning permission. The waste transfer station was reasonably characterized as a "waste" use akin to that required by the policy, and the planning judgment was well within the range of reasonableness.

The court emphasized that the County Council’s submission to judgment in earlier proceedings related to a different statutory procedural failure and did not undermine the lawfulness of the current planning permission.

Overall, the court concluded that the County Council’s screening opinion and planning decision were lawful, rational, and supported by evidence, and that the claimants’ challenges on both grounds failed.

Holding and Implications

The claim for judicial review is dismissed.

The court upheld the planning permission granted by the Defendant for the waste transfer station. The screening process under the EIA regime was found to be lawful and properly reasoned, including the approach to cumulative effects and project splitting. The departure from Policy GD8 was acknowledged and balanced appropriately in the planning decision, with adequate reasons provided. The decision has the direct effect of confirming the validity of the planning permission and does not set any new precedent beyond affirming established principles regarding EIA screening and planning policy departures.
