3. Prior to commencement, a scheme of sound mitigation (at source & in transmission path) to satisfy the criteria of the Noise Survey and Plant Noise Egress Assessment dated 11th July 2025 shall be submitted to and approved by the Local Planning Authority. REASON: In order to ensure compliance with Policy EN18 of the Flintshire Local Development Plan.
4. Facilities shall be provided and retained within the site for the loading, unloading, parking and turning of vehicles. Such facilities being completed prior to the proposed development being brought into use. REASON: To ensure that adequate parking and manoeuvring space is made and to avoid the necessity for reversing movements into or from the highway in the interests of highway safety and maintaining the free flow of traffic on the adjoining highway.
5. No development or phase of development shall commence until the following components of a scheme to deal with the risks associated with contamination at the site, has been submitted to and approved in writing by the Local Planning Authority. 1. A preliminary risk assessment which has identified: • all previous uses • potential contaminants associated with those uses • a conceptual model of the site indicating sources, pathways and receptors • potentially unacceptable risks arising from contamination at the site 2. A site investigation scheme, based on (1) to provide information for a detailed assessment of the risk to all receptors that may be affected, including those off site. 3. The results of the site investigation and the detailed risk assessment referred to in (2) and, based on these, an options appraisal and remediation strategy giving full details of the remediation measures required and how they are to be undertaken. 4. A verification plan providing details of the data that will be collected in order to demonstrate that the works set out in the remediation strategy in (3) are complete and identifying any requirements for longer-term monitoring of pollutant linkages, maintenance and arrangements for contingency action. The remediation strategy and its relevant components shall be carried out in accordance with the approved details. REASON: To ensure the risks associated with contamination at the site have been fully considered prior to commencement of development as controlled waters are of high environmental sensitivity; and where necessary remediation measures and long-term monitoring are implemented to prevent unacceptable risks from contamination in compliance with Policy EN16 Of the Flintshire Local Development Plan.
6. Prior to the operation of the development a verification report demonstrating completion of works set out in the approved remediation strategy and the effectiveness of the remediation shall be submitted to and approved in writing by the Local Planning Authority. The report shall include results of sampling and monitoring carried out in accordance with the approved verification plan to demonstrate that the site remediation criteria have been met. It shall also include a long-term monitoring and maintenance plan for longer-term monitoring of pollutant linkages, maintenance and arrangements for contingency action, as identified in the verification plan. The long-term monitoring and maintenance plan shall be carried out in accordance with the approved details. REASON: To ensure the methods identified in the verification plan have been implemented and completed and the risk associated with the contamination at the site has been remediated prior to occupation or operation, to prevent both future users of the land and neighbouring land are minimised, together with those to controlled waters, property and ecological systems, and to ensure that the development can be carried out safely without unacceptable risks to workers, neighbours and other offsite receptors in compliance with Policy EN16 of the Flintshire Local Plan.
7. If, during development, contamination not previously identified is found to be present at the site then no further development (unless otherwise agreed in writing with the Local Planning Authority) shall be carried out until a remediation strategy detailing how this unsuspected contamination shall be dealt with has been submitted to and approved in writing by the Local Planning Authority. The remediation strategy shall be carried out as approved. REASON: To ensure the risks associated with previously unsuspected contamination at the site are dealt with through a remediation strategy, to minimise the risk to both future users of the land and neighbouring land, and to ensure that the development can be carried out safely without unacceptable risks in compliance with Policy EN16 of the Flintshire Local Development Plan.
8. To assist in the preparation of a suitable preliminary risk assessment and an appropriate conceptual site model (CSM), NRW recommends that developers should refer to the Environment Agency "Land Contamination Risk Management" (updated 2023), Welsh Local Government Association "Development of Land Affected by Contamination: A Guide for Developers" (2023) and the Environment Agency "Approach to Groundwater Protection" (2017) when undertaking further works at this site.
