Factual and Procedural Background
This opinion concerns an application under section 288 of the Town and Country Planning Act 1990. The Plaintiff challenges a planning inspector's decision dismissing an appeal against the deemed refusal of an application for planning permission. The application related to the erection of a concrete plant with associated batching offices and vehicle parking, a new industrial unit with parking, and a new parking area for an existing unit at Unit 1, Porte Marsh Industrial Estate, Calne, Wiltshire. The appeal was decided on written representations.
The local planning authority, Company A, had resolved to refuse planning permission following receipt of numerous objections from local residents, a civic society, and businesses. The site backs onto residential properties on Oxford Road. The Plaintiff proposed dust mitigation measures which were accepted by the council’s Environmental Health Officer, but Company A opposed the appeal on the basis that the proposal failed to comply with policy RE17 of the North Wiltshire Local Plan (2001) and guidance in PPS23, which require that new employment development should not seriously affect local amenities.
The inspector identified the main issue as the effect of the proposal on local amenity, focusing on noise, dust, and the visual impact of a proposed noise screen building. The inspector concluded that while traffic impacts were acceptable, the development would cause a significant increase in dust affecting residential and industrial neighbours, the noise assessment was unclear and reinforced unsuitability, and the visual impact of the 9m high building would harm the enjoyment of adjacent rear gardens. The appeal was dismissed accordingly.
Legal Issues Presented
- Whether the inspector erred in law or gave inadequate reasons in concluding that the proposed development would cause serious harm to local amenities due to dust, noise, and visual impact.
- Whether the existence of a comprehensive pollution control regime under the Pollution Prevention and Control Act 1999 and related regulations precludes a planning authority from refusing permission on grounds related to dust emissions.
- Whether the inspector misinterpreted policy RE17 in relation to design considerations, specifically regarding the height of the proposed building.
Arguments of the Parties
Appellant's Arguments
- The inspector misunderstood the legal effect of the pollution control regime, which comprehensively regulates emissions and would prevent serious harm from dust.
- Given the regulatory controls, the inspector should have concluded that the council could control dust emissions effectively, making refusal on this ground unjustified.
- The inspector failed to provide adequate reasons for rejecting the Environmental Health Officer’s acceptance of mitigation measures.
- The inspector’s conclusion that dust would seriously harm amenities was Wednesbury unreasonable because it ignored the primacy of the pollution control authority’s judgment.
- The inspector misinterpreted policy RE17 by treating the height of the proposed building as a design issue when it was not.

| Gateshead Metropolitan Borough Council v Secretary of State for the Environment (1994) 71 P & CR 350 |
Planning authorities may consider air emissions as a material planning consideration and may take into account the pollution control regime, but are not obliged to defer to it. |
The court confirmed that planning authorities can focus on land use impacts rather than duplicating pollution control but are not bound to subordinate their judgment to the pollution control authority. |
| R v Bolton Metropolitan Borough Council, exp Kirkman [1998] JPL 787 |
Similar principle that planning authorities may consider pollution impacts but may rely on pollution control regimes without being bound by them. |
The court applied the principle that planning authorities should complement but not duplicate pollution control regimes in their decisions. |
Court's Reasoning and Analysis
The court analysed the relationship between planning control and pollution control regimes. It acknowledged the comprehensive regulatory framework under the Pollution Prevention and Control Act 1999 and the 2000 Regulations, which impose conditions on permits to prevent or reduce pollution, including dust emissions that impair amenities.
However, the court emphasised that planning authorities retain the discretion to consider the impact of emissions on amenity as a material planning consideration. The court rejected the argument that the pollution control regime must have primacy over planning judgments on amenity impacts. It noted that PPS23 advises planning authorities to assume pollution controls will be properly applied but to focus on the acceptability of the land use and its impacts rather than control of emissions per se.
The court found that the inspector had properly considered the mitigation measures and explained why, despite them, dust emissions would cause significant harm to residential and industrial neighbours’ amenities. The inspector’s reasoning was not legally flawed or inadequately reasoned, nor was it Wednesbury unreasonable.
Regarding noise, the court noted the inspector did not rely on noise as a reason for dismissal, and thus no detailed consideration was necessary.
On visual impact, the court held that policy RE17 explicitly includes height as a design consideration. The inspector’s concern about the 9m high building’s overbearing effect was therefore a proper application of the policy.
Holding and Implications
The court REFUSED the application to challenge the inspector’s decision.
The direct effect is that the inspector’s dismissal of the appeal stands, upholding the refusal of planning permission due to the adverse effects of dust and visual impact. No new legal precedent was established; the decision affirms the established principle that planning authorities may consider amenity impacts independently of pollution control regimes.
