P02Tony Gee, dated 22nd January 2021 and (various dates) March 2019 Isle of Man, Department of Infrastructure, Planning Application for the Extension of Dredged Material, Dewatering at Peel, Environmental Impact Assessment Report, The Bates Partnership, dated April 2025 Isle of Man, Department of Infrastructure, Planning Application for the Extension of Dredged Material, Dewatering at Peel , Non-Technical Summary of the Environmental Impact Assessment Report, The Bates Partnership, dated April 2025 Traffic Count Data, Mill Road, Peel 2024 Traffic Count Data, Heathfield Drive, Peel 2024 This decision has been made for the following reasons(s) The Officer's report on previously approved Planning Application Ref. 18/01293/B, in 2019 concluded that the site could be developed as temporary de-watering lagoon, together with the associated pipelines, without prejudicing the long-term development of the lagoon site in accordance with its land-use zoning in the Local Plan, but that the grant of planning permission should ensure by condition that the site is restored to it original condition as agricultural land. The position now remains essentially unchanged, except that the planning application for the remediation of the Cross Vein Mine has now been submitted as a separate but concurrent application. The timescales for the proposed works linked to the Cross Vein Mine remediation scheme tie in with the proposed end date for restoration of the Peel de-watering lagoon, and on this basis it is recommended, in principle, that this application, also be approved essentially with a shorter and amended set of similar conditions to those contained in Planning Permission Ref. 18/01293/B, to the extent that these needs only to deal with the decommissioning of the lagoon and discharge pipeline and restoration of Field 315179 subject to the proposal being acceptable in terms of the traffic and environmental impacts. The conclusions of the assessment in the updated EIA report of the impact across the range of environmental effects has not change significantly since they were considered when the original application for the construction of the de-watering lagoon and discharge pipeline was approved in March 2019, with the impact being assessed as being negligible to minor averse, but of only limited duration, with the lagoon site and the route of the discharge pipeline being restored to their original condition by 31st December 2027. The application can accordingly be considered to be compliant with The Isle of Man Strategic Plan 2016, Strategic Policies 1,2, 4 and 10, Waste Policy 1, General Policy 2, and Environment Policies, 4, 7, 22 and 24 and Recreation Policy 5.
