The temporary activity is required to facilitate the delivery of the Balthane Junction Improvement Scheme (Planning Application 22/00567/B) and addresses a critical shortfall in the Island’s current waste‑management infrastructure. The application seeks temporary planning consent for the controlled processing of hazardous asphalt waste, in accordance with the Isle of Man Government’s strategic planning and environmental policies, including Waste Policy 1 and Environment Policy 24 of the Strategic Plan. The proposed operation will be undertaken under a Waste Direction issued by the Department of Environment, Food and Agriculture (DEFA) and will be subject to regulatory oversight by the Environmental Protection Unit (EPU) to ensure full compliance with statutory environmental safeguards. - 1.1 Background At present, the Isle of Man has no licensed facility capable of receiving or processing AWCCT. This gap represents a significant barrier to the safe, compliant, and sustainable management of hazardous asphalt waste generated by major infrastructure projects. The proposed temporary use of Turkeyland Quarry will enable the cold recycling of this material, consistent with the waste‑hierarchy principles set out in the Department of Infrastructure’s Waste Strategy and will ensure that material suitable for reuse can be retained and reintegrated into the Island’s road network. The temporary processing activity will be strictly time‑limited to align with the construction period of the Balthane Junction Improvement Scheme, currently estimated at 6–8 months. Although AWCCT processing will occur during two discrete operational phases, the temporary permission sought covers the full construction period to allow for safe site establishment, secure containment, controlled storage, and appropriate reinstatement upon completion. The EPU will regulate the activity under the Water Pollution Act 1993 and the Public Health Act 1990, ensuring that stringent environmental controls are in place. These will include: impermeable hardstanding, sealed drainage and water‑management systems, emissions and odour monitoring, and full hazardous‑waste tracking and documentation. Enabling local processing avoids the environmental risks and financial costs associated with exporting hazardous material off‑Island, removes reliance on landfill disposal, and supports the principles of a circular economy. Cold recycling ensures that the material is safely reused in road construction, Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case maximising the value of existing resources and supporting the Island’s sustainability objectives, including reduced waste to landfill and improved environmental resilience. In parallel with this temporary proposal, the Department of Infrastructure is progressing a long‑term strategy aimed at establishing a licensed facility at Turkeyland Quarry for the permanent storage and processing of AWCCT. This future initiative is separate from, and not dependent upon, the temporary planning application. The temporary activity does not prejudice any future planning consideration but provides an immediate and proportionate solution to current infrastructure needs. - Chapter 2 –Justification - 2.0 Environmental Benefits of Reusing AWCCT in Road Construction Reusing AWCCT in the roundabout construction offers several environmental benefits and aligns with established waste management and environmental protection standards. It eliminates the need for landfill disposal of hazardous material, a solution not currently feasible on the Isle of Man due to the absence of licenced facilities, and reduces demand for virgin aggregates, thereby conserving natural resources. Local reuse also minimises transportrelated emissions and supports circular economy principles by recovering and repurposing existing materials. This approach is consistent with the Isle of Man’s Waste Regulation framework under the Public Health Act 1990, the Collection & Disposal of Waste Regulations 2000, and the Import & Export of Waste Regulations 2001, which promote waste recovery and environmentally sound management of hazardous materials. It also reflects best practices outlined in the UK’s Regulatory Position Statement RPS 157, which permits the storage, treatment, and reuse of asphalt waste containing coal tar (AWCCT) under controlled conditions, provided environmental and human health risks are mitigated. Importantly, the hazardous material is encapsulated within a cold recycled bound pavement layer, significantly reducing the risk of leaching and exposure. This method aligns with the SEPA Position Statement WAS-PS-06, which recognises cold recycling as a sustainable treatment option that reduces environmental impact and supports the reuse of hazardous road materials in construction. Chapter 3 –Planning and Regulatory Oversight - 3.0 Overview There is currently no licensed facility on the Isle of Man available to reprocess Asphalt Waste Containing Coal Tar (AWCCT). This presents a significant barrier to the safe and compliant reuse of the material. To enable processing, Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case temporary planning approval is required for the use of Turkeyland Quarry as a licensed landfill site for the temporary processing of AWCCT. The permission sought is limited in scope and duration and is required to support the Balthane Junction Improvement Scheme. Conditions attached to any approval will ensure environmental protection, containment, and operational safety, consistent with the Island’s statutory planning framework under the Town and Country Planning Act 1999. The Environmental Protection Unit (EPU), part of the Department of Environment, Food and Agriculture (DEFA), will oversee the temporary processing activities under an approved Direction issued to the Department of Infrastructure. The EPU regulates waste and water pollution under the Water Pollution Act 1993 and the Public Health Act 1990. For this project, EPU oversight will ensure the site operates on impermeable hardstanding with sealed drainage, maintains appropriate containment systems, adheres to hazardous waste tracking requirements, and complies with all environmental protection measures. These safeguards ensure the temporary activity can be carried out safely and within the Island’s regulatory framework. 3.1 Policy Context The proposed temporary processing of Asphalt Waste Containing Coal Tar (AWCCT) at Old Turkeyland Quarry fully accords with the principles and requirements set out within Waste Policy 1, which establishes the strategic framework for sustainable waste management on the Isle of Man. A clause‑by‑clause assessment is provided below: - (a) Promote the waste hierarchy, prioritising reduction, reuse and recycling over disposal The proposal directly supports the waste hierarchy by enabling reuse of AWCCT as part of the Balthane Junction Improvement Scheme. Without this temporary processing activity, the only remaining option would be off‑island disposal or long‑term storage, both of which are environmentally inferior. The project therefore maximises resource recovery and minimises reliance on disposal. - (b) Encourage sustainable waste management infrastructure and reduce reliance on landfill There is currently no licensed hazardous asphalt processing facility on the Island. This proposal provides essential interim capacity to safely treat AWCCT and prevents this hazardous material from entering landfill. It supports the development of longer‑term, on‑island hazardous waste solutions and aligns with the Department’s intent to expand future licensed capabilities at Turkeyland Quarry. - (c) Ensure that waste development does not give rise to unacceptable environmental, health or amenity impacts Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case The proposal incorporates sealed drainage, impermeable hardstanding, secondary and tertiary containment, dust and noise controls, and full oversight by the Environmental Protection Unit (EPU). The activity is confined to a licensed landfill site away from residential receptors. These measures ensure no significant adverse impacts on public health, amenity, land, air or controlled waters. - (d) Support the sustainable transportation of waste and minimise environmental impacts from waste movement Processing AWCCT locally avoids the extensive environmental burden of shipping hazardous road material off‑island for treatment. Transport is limited to short internal haulage between sites, significantly reducing vehicle miles and associated emissions. - (e) Direct waste activities to appropriate and suitably located sites Turkeyland Quarry already operates under a waste processing licence, benefits from a controlled access environment, has robust infrastructure, and is remote from sensitive receptors. The site is therefore an appropriate and policy‑compliant location for the temporary processing of hazardous asphalt waste. - (f) Ensure adequate containment, design safeguards and mitigation to protect the environment The scheme includes: a concrete maturation pad with sealed joints a 89,000‑litre sealed drainage channel with penstock control bunded storage and processing systems an inspection and maintenance regime aligned with CIRIA C736 These measures ensure full compliance with this clause. - (g) Enable waste solutions that are proportionate, temporary where necessary, and clearly justified The proposal is strictly time‑limited, linked solely to delivery of the Balthane Junction Improvement Scheme. It represents the minimum level of development required to safely manage the identified waste stream and prevent environmental harm. It is therefore proportionate, necessary and fully consistent with clause (g). 3.2 Environmental Impact Assessment (EIA) Requirements This planning statement supports the position that a full Environmental Impact Assessment (EIA) is not required for the proposed temporary waste processing activity. Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case The development will occur entirely within the confines of an existing licensed waste management facility, using established hardstanding, drainage, and containment infrastructure. No new land take, excavation, or emissions sources beyond those already associated with the licensed landfill site are proposed. The activity is limited in scale, temporary in duration, and subject to stringent environmental controls. In accordance with Environment Policy 24(ii), the application is accompanied by appropriate and proportionate environmental information, demonstrating how potential impacts—including dust, noise, drainage, emissions to controlled waters, and hazardous materials management—will be mitigated. These measures ensure compliance with the Strategic Plan’s environmental protection objectives. Although the proposal meets the technical threshold for EIA screening due to the classification of the material, the screening assessment confirms that no likely significant environmental effects will arise, given: the location within a licensed landfill site the limited and temporary nature of the activity the robust containment and control measures ongoing regulation by the Environmental Protection Unit (EPU) Accordingly, a full EIA would not provide any material additional environmental assurance beyond the detailed information already submitted. The environmental information included with the planning application is therefore sufficient to support a robust and informed planning determination without the need for further assessment. Chapter 4 –Site Assessment and Pollution Prevention 4.0 Site Assessment Two potential sites were identified and assessed for their suitability to accommodate the recycling of Asphalt Waste Containing Coal Tar (AWCCT), based on spatial capacity, operational feasibility, proximity to the Balthane Junction, and environmental constraints. Site 1 - Site Compound: Located adjacent to the Balthane Roundabout, Site 1 occupies land previously occupied by the demolished properties at Railway Terrace (see Figure 4.1 below). Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case - Figure 4.1: Site Compound Location (In Green) The compound has insufficient space to support aggregate processing and batching operations. Its proximity to existing buildings introduces several risks, including health and safety concerns, challenges in maintaining environmental controls, and difficulty achieving regulatory compliance for hazardous waste processing. These factors make the location unsuitable for AWCCT treatment. Site 2 - Old Turkeyland Quarry: Turkeyland Quarry is a larger facility currently operating under a waste processing licence (see Figure 4.2 below). It Is located approximately 1.6 miles from the Balthane Junction, offering convenient access while maintaining a safe distance from residential and commercial areas. - Figure 4.2: Old Turkeyland Quarry Location ![An aerial location map highlighting a specific site in red, situated near Turkeyland Quarry and Ronaldsway Airport.](https://images.planningportal.im/2025/12/7253301.jpg) Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case Turkeyland Quarry presents a significantly more suitable option for the temporary processing of AWCCT due to the following advantages: Size and Infrastructure: The site offers a large operational footprint with a robust concrete hardstanding, capable of supporting aggregate processing and cold recycling activities. Environmental Controls: It includes a substantial surface water drainage channel with a penstock-controlled outlet, enabling effective containment and controlled removal of leachate. Licensing and Operational Experience: Although not currently licensed for hazardous waste, the site operates under an existing waste processing licence and has experienced staff familiar with waste handling protocols. Security and Safety: The site benefits from a secure perimeter, controlled access, and natural buffer zones, reducing risks associated with noise, dust, and odour. Strategic Fit: Its location and existing infrastructure align with the Department of Infrastructure’s long-term strategy to establish a licensed facility for AWCCT processing, supporting the Island’s sustainability and waste management goals. Location: Its location is away from residential areas These combined factors make Old Turkeyland Quarry the preferred location for the proposed temporary processing operation. 4.1 Pollution Prevention Best practice for waste processing compounds is set out in CIRIA C736 – Containment Systems for the Prevention of Pollution (2014), which outlines requirements for impermeable surfaces, sealed drainage systems, secondary/tertiary containment, together with inspection and maintenance expectations. Table 4.1 summarises the relevant principles and how they translate at a general level into project-specific implications that remain within CIRIA’s scope. Table 4.1: Overview of CIRIA (2014) best practice guidance Feature CIRIA (2014) Guidance Project-specific implications |Feature|CIRIA (2014) Guidance|Project Specific Implications| |---|---|---| |Secondary containment|Design to contain loss of contents with allowance for rainfall and potential fire-water; use materials compatible with stored substances; provide controlled drainage to a contained point; avoid uncontrolled overflow routes; minimise wall/floor penetrations and protect structural integrity; incorporate safe access for inspection and clean-out.|Provide bunded storage/handling areas for relevant liquids associated with asphalt processing.

Undertake periodic integrity checks where CIRIA indicates. Retain records for the period required by licence/permit conditions.| 4.2 Secondary Containment Processing of Asphalt Waste Containing Coal Tar (AWCCT) will be undertaken on the maturation pad at Turkeyland Quarry. The maturation pad serves as a secondary containment system, required to prevent pollution from leachate or runoff during the treatment and storage of AWCCT. The pad is constructed of concrete with a perimeter upstand to intercept runoff, ensuring that any contaminants are effectively managed. A site-specific risk assessment, aligned with CIRIA C736’s three-tier methodology, has confirmed that the containment measures are appropriate for the nature and volume of AWCCT being processed. Figure 4.3: Turkeyland Quarry: Maturation Pad Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case - 4.3 Impermeable Surfaces The maturation pad at Turkeyland Quarry is constructed of reinforced concrete with sealed joints, forming a robust and impermeable surface suitable for the processing of AWCCT. The sealed joints prevent ingress of contaminants and eliminate pathways for leachate migration, ensuring full containment of hazardous materials, see Figure 4.4 below for details. This aligns with the principles outlined in CIRIA C736, which emphasises the importance of low-permeability surfaces and joint integrity in secondary containment systems. The pad’s construction supports effective pollution prevention, facilitates controlled drainage, and enables compliance with environmental protection standards. Figure 4.4: Turkeyland Quarry: Sealed Joints in Maturation Pad - 4.4 Sealed Drainage Systems Surface water runoff from the maturation pad will be directed to a large concrete drainage channel 1.24m wide x 65.53m long x 1.10m deep, as illustrated in Figure 4.5 below. The channel has sufficient capacity to store approximately 89,000 litres of runoff, ensuring containment during rainfall events or operational washdown. Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case Figure 4.5: Turkeyland Quarry: Main Drainage Channel Runoff will be retained within the channel and controlled via a penstock valve, which prevents discharge to the existing sea outfall. The contaminated runoff will be removed by tanker and transported to the Meary Veg sewage treatment plant for appropriate disposal in accordance with environmental regulations and best practice. There will be no discharge of leachate to sea. This system ensures that surface water is effectively managed and that pollutants are contained and treated responsibly, supporting compliance with CIRIA C736 guidance on pollution prevention. 4.5 Tertiary Containment A tertiary containment measure is in place at Turkeyland Quarry in the form of a perimeter upstand surrounding the maturation pad, as illustrated in Figure 4.6. The upstand is intended to contain surface water runoff and prevent uncontrolled discharge beyond the operational area. Figure 4.6: Turkeyland Quarry: Upstand to Hardstanding Edge Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case The upstand acts as a physical barrier, ensuring that any residual or accidental runoff is retained within the site boundary. This measure complements the primary and secondary containment systems and aligns with the principles of CIRIA C736, which advocates for multi-tiered containment strategies to mitigate pollution risk. In the event of a containment breach or extreme weather event, the upstand provides a final safeguard, allowing for controlled management and disposal of contaminated water, thereby supporting compliance with environmental regulations and best practice. - 4.6 Inspections and Maintenance Environmental safeguards and operational controls will be implemented at Turkeyland Quarry to manage potential impacts from the processing of Asphalt Waste Containing Coal Tar (AWCCT). These controls will cover, as a minimum: Emissions to air (dust and particulates) Odour, noise, and vibration Emissions to land and surface/ground waters (including runoff and leachate) Mud and debris management Litter control Site security and access control Traffic management All controls will be proportionate to the assessed risk and aligned with best practice guidance, including that referenced in Section 5.4 of CIRIA C736. Full details will be provided in the Department’s Waste Direction submission, including a Working Plan and compound layout prepared by the appointed Contractor. - 4.7 Pre-Mobilisation Audit Prior to mobilisation, the Contractor shall undertake a comprehensive on-site audit to confirm: Hardstanding Integrity: Inspection of surface condition and joint integrity to prevent infiltration and ensure structural integrity. Perimeter Upstand: verification of continuity and containment capacity to prevent uncontrolled discharge. Drainage Channel: Assessment of storage capacity and management protocols to handle expected volumes. Penstock Control and Tanker Export: Evaluation of operational readiness and compliance with discharge and export procedures Audit outcomes will inform updates to the working plan. Chapter 5 –Compound and Temporary Plant 5.0 Compound Regulatory Requirements The temporary compound will operate under a Waste Direction issued by the Department of Environment, Food and Agriculture (DEFA), with the Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case Environmental Protection Unit acting as the regulatory assessor. The compound will be managed in accordance with UK best practice, including the guidance set out in Regulatory Position Statement (RPS) 157. The key regulatory requirements include: Storage Requirements: Waste must be stored in secure containers. Storage volumes are subject to defined limits. No waste shall be stored for longer than 12 months. Different waste types must be stored separately. Where waste is stored in containers, the total quantity at any one time must not exceed 20 containers. The person storing the waste must either own the containers or have the owner’s consent. Environmental Protection Measures: Waste storage facilities must be secure and incorporate safeguards against pollution and unauthorized access. Discharge of pollutants into controlled waters without consent is prohibited. Hazardous liquids (including leachates) must be stored within secondary containment systems on impermeable surfaces with sealed drainage. 5.1 Source of Asphalt Waste Containing Coal Tar (AWCCT) Asphalt Waste Containing Coal Tar (AWCCT) is classified as hazardous waste due to the presence of polycyclic aromatic hydrocarbons (PAHs). A total of approximately 1,375 tonnes of AWCCT will be managed at the compound, comprising: 375 tonnes to be transported from the Balthane Roundabout site. 1,000 tonnes currently stored in skips at various locations across the island. To ensure compliance with regulatory thresholds and best practice (including RPS 157), the AWCCT will be processed in controlled phases. This approach ensures that the total volume of AWCCT stored onsite at any one time remains within the permitted limits of: 500 m³ if stored uncovered, or 1,000 m³ if stored under cover. The temporary nature of the operation ensures that no material will be stored for longer than 12 months. Storage volumes and durations will be actively monitored and managed to maintain full compliance throughout the project. For indicative planning purposes, a notional processing rate of approximately 60 tonnes per hour is considered achievable, subject to plant availability and logistical constraints. Final output rates and processing durations will be confirmed following the appointment of a specialist contractor. Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case - 5.2 Working Hours and Duration AWCCT processing activities will be restricted to the following hours: Monday to Saturday: 07:00 –19:00 The duration of each processing phase will be defined in the detailed construction programme, which will be developed in collaboration with the appointed specialist contractor. While the overall project is anticipated to be completed within 6–8 months, the specific processing methodology, production rates, and phase durations will be determined based on the contractor’s proposed approach and operational logistics. - 5.3 Plant and Equipment The specific plant and equipment required for AWCCT processing will be confirmed upon appointment of a specialist contractor. However, based on typical UK operations, the following activities and equipment are anticipated: Crushing and screening of AWCCT material. Stockpiling of processed materials. Batching and transportation to the work site. Additional aggregate bins or stockpiles, particularly for imported primary fine aggregate, which is expected to be required. - 5.4 Crushing & Screening The requirement for crushing and screening will depend on the size and condition of the incoming feedstock. In a worst-case scenario, both primary and secondary crushing may be necessary. Primary crushing will reduce larger material to a manageable size for further processing (see Figure 5.1: Primary Crushing Operation). Figure 5.1: Primary Crushing Secondary crushing and screening will then refine the material into the required coarse aggregate size fractions. A mobile crushing and screening Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case plant, such as that shown in Figure 5.2: Mobile Secondary Crushing and Screening, is likely to be deployed. Figure 5.2: Secondary Crushing and Screening In addition to size separation, this equipment can remove deleterious physical materials. Excavators will be used to feed the crushers and manage stockpiles. 5.5 Mobile Batching Plant The mobile batching plant comprises silos for cement and water, along with a batching unit, typically based on a modified crusher with a conveyor for loading trucks. This specialist plant folds into an HGV trailer-sized unit for transportation. For safe and efficient operation, an overall working area in the order of 2,000 to 2,500 m² is typically required for mobile batching, exclusive of wider quarry operations (see Figure 5.3: Mobile Batching Plant). Figure 5.3: Mobile Batching Plant Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case - 5.6 Decommissioning Upon completion of the AWCCT processing activities and the conclusion of the project, the temporary compound will be fully decommissioned. This will include the removal of all plant, equipment, and temporary infrastructure associated with the compound operations. All stockpiles and residual materials will be cleared from the site, and any waste will be disposed of in accordance with applicable regulatory requirements. The decommissioning process will be undertaken in a timely and controlled manner to minimise any residual environmental impact and ensure the site is left in a safe and stable condition. Chapter 6 –Transport Statement - 6.0 I ntroduction This Transport Statement supports the proposed temporary processing of Asphalt Waste Containing Coal Tar (AWCCT) at Old Turkeyland Quarry. It confirms Balthane Road as the primary access route, sets out the expected vehicle movements generated by the activity, and demonstrates that the surrounding highway network has sufficient capacity to safely and efficiently accommodate the temporary uplift. - 6.1 Role of Balthane Road Balthane Road is an established HGV access corridor serving the Balthane Industrial Estate, which contains over 200 commercial units and accommodates significant daily commercial traffic. The route forms part of the southern transport corridor, which is subject to planned improvements to increase junction capacity, enhance traffic flow, and upgrade drainage infrastructure. Its existing function, design, and traffic profile make it suitable for accommodating the temporary increase in HGV activity associated with the AWCCT processing operation. - 6.2 Access to Old Turkeyland Quarry Access to Old Turkeyland Quarry will be taken from the A5 via Balthane Road and through the Balthane Industrial Estate. This route forms an established and frequently used commercial HGV corridor serving a large number of industrial and logistics operations within the estate. As such, it is already designed to accommodate regular commercial vehicle movements and does not require any modification or additional infrastructure to support the proposed temporary processing activities. On the approach to the Old Turkeyland Quarry, Balthane Road narrows, with formal passing places available to facilitate two‑way HGV movements. Although the road geometry requires occasional use of these passing places, opposing HGV encounters occur infrequently in practice due to existing traffic patterns and the relatively low volume of HGVs travelling to this specific location. The road’s current layout and operational characteristics are Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case therefore considered suitable for accommodating the anticipated temporary increase in HGV traffic associated with the proposal. - 6.3 Vehicle Movement Forecast Processing Programme: A total of approximately 1,375 tonnes of AWCCT will be processed in two defined phases, each lasting approximately two weeks. One phase will take place during Phase 1 of the construction programme, and the second during Phase 2. HGV Load Assumptions: A standard rigid HGV typically carries 18–20 tonnes of asphalt‐type material. A conservative 20‐tonne load assumption has been adopted to ensure movements are not understated. This reflects the typical vehicle configuration routinely accessing the industrial estate and Old Turkeyland Quarry. HGV Movements: - • Inbound AWCCT loads: ~69 - • Outbound processed loads: ~69 - • Total HGV movements: ~138 With two two‐week processing phases (24 operational days), this equates to approximately 5–6 HGV movements per day during each active processing phase. Tanker Movements: The site’s sealed drainage and containment system will require periodic removal of collected runoff. One tanker collection per week is anticipated, resulting in approximately 12 tanker movements across the full programme. - 6.4 Capacity and Impact Assessment The projected uplift of approximately 5–6 HGV movements per day during each two‐week processing phase is negligible relative to existing HGV activity associated with the industrial estate. Vehicle movements will occur over a 12‐ hour working period (07:00–19:00), ensuring no peak‐hour pressure is introduced. - 6.5 Conclusion The temporary processing of AWCCT at Old Turkeyland Quarry will generate low, short‐duration traffic levels that can be comfortably accommodated within the existing road network. Balthane Road is an appropriate and established HGV corridor with capacity to absorb the temporary uplift without resulting in any material adverse transport impact. The proposal is therefore acceptable in highway and access terms. Department of Infrastructure December 2025 Temporary Processing of AWCCT at Turkeyland Quarry Planning Statement of Case Chapter 7 –Conclusion 7.0 Summary The temporary processing of Asphalt Waste Containing Coal Tar (AWCCT) at Old Turkeyland Quarry represents a necessary, proportionate, and environmentally robust approach to enabling the delivery of the Balthane Junction Improvement Scheme. In the absence of any licensed on‑island facility capable of treating AWCCT, the proposed activity provides a safe and controlled solution that accords with the Isle of Man Government’s Waste Strategy, Waste Policy 1 (a–g), and Environment Policy 24. The proposal also aligns with the principles of the waste hierarchy by facilitating reuse over disposal and by minimising the need for off‑island transport of hazardous material. Turkeyland Quarry is demonstrably suitable for this temporary activity, offering impermeable hardstanding, sealed drainage, established containment measures, and regulatory oversight by the Environmental Protection Unit (EPU). The proposal is time‑limited, environmentally safeguarded, and designed to prevent any long‑term impacts, with full decommissioning and reinstatement to occur upon completion of the works. The supporting Transport Statement confirms that Balthane Road is an established HGV route serving over 200 commercial units within the Balthane Industrial Estate and is fully capable of accommodating the temporary increase in vehicle movements associated with AWCCT processing. The Transport Statement also demonstrates that the two processing phases, each lasting approximately two weeks, will generate only 5–6 HGV movements per day, together with minimal ancillary tanker movements. These traffic levels are negligible within the context of baseline industrial‑estate traffic and will not give rise to any material highway safety or capacity concerns. Overall, the proposal is environmentally sound, operationally feasible, and supported by a clear evidence base demonstrating that all environmental, regulatory, and transport considerations have been appropriately addressed. The development presents no significant adverse impacts and provides an essential, policy‑compliant mechanism for enabling wider infrastructure improvements at Balthane Junction. Approval of this application will allow the Department of Infrastructure to progress the scheme efficiently while maintaining strong environmental protection, sustainable practice, and responsible management of hazardous material.
