The application covers a 3.8-hectare site on former agricultural grazing land about 1.6km south-east of Peel, where a silt store has operated since 2015 to receive dredged material from Peel Marina. The proposal is to permanently retain the deposited material on site, carry out a restoration scheme including bund stabilisation, an engineered cap, surface water drainage, monitoring wells, woodland planting, and returning parts of the site to grazing, and then maintain the facility under an aftercare regime. The key planning issues were whether there was a genuine need for the facility with no viable alternative, and whether the environmental impacts on the water environment, landscape, ecology, traffic, noise, and air quality were acceptable. The EIA concluded that retention and restoration was preferable to doing nothing and to relocation, as alternative sites such as Wrights Pit North and Turkeylands quarries lacked the necessary licences or void capacity at the time. The decision notice confirmed an acknowledged national need under the Isle of Man Waste Management Strategy, with no reasonable and acceptable alternative, and that environmental impacts were judged acceptable subject to nine conditions.
The Committee approved the application because retaining the material on site was identified as the best available option for a problematic waste with an overriding national need and no reasonable alternative, in line with Isle of Man Strategic Plan Waste Policy 1 and General Policy 3. Environmental impacts on ecology, water, landscape, traffic, noise, and air quality were assessed and found to be acceptable, with mitigation measures secured through conditions.
Waste Policy 1
General Policy 3
General Policy 3: Development will not be permitted outside of those areas which are zoned for development on the appropriate Area Plan with the exception of: (a) essential housing for agricultural workers who have to live close to their place of work; (Housing Policies 7, 8, 9 and 10); (b) conversion of redundant rural buildings which are of architectural, historic, or social value and interest; (Housing Policy 11); (c) previously developed land (1) which contains a significant amount of building; where the continued use is redundant; where redevelopment would reduce the impact of the current situation on the landscape or the wider environment; and where the development proposed would result in improvements to the landscape or wider environment; (d) the replacement of existing rural dwellings; (Housing Policies 12, 13 and 14); (e) location-dependent development in connection with the working of minerals or the provision of necessary services; (f) building and engineering operations which are essential for the conduct of agriculture or forestry; (g) development recognised to be of overriding national need in land use planning terms and for which there is no reasonable and acceptable alternative; and (h) buildings or works required for interpretation of the countryside, its wildlife or heritage. 6.4 Planning Agreements 6.4.1 Where development is acceptable and in accordance with the provisions of this Plan and the relevant Area Plan, but raises issues which cannot be addressed by the imposition of planning conditions, the Department will seek to conclude an Agreement with the developer under Section 13 of the 1999 Town and Country Planning Act.
Strategic Policy 4
Strategic Policy 4: Proposals for development must: (a) Protect or enhance the fabric and setting of Ancient Monuments, Registered Buildings (1), Conservation Areas (2), buildings and structures within National Heritage Areas and sites of archaeological interest; (b) protect or enhance the landscape quality and nature conservation value of urban as well as rural areas but especially in respect to development adjacent to Areas of Special Scientific Interest and other designations; and (c) not cause or lead to unacceptable environmental pollution or disturbance. 4.3.8 The design of new development can make a positive contribution to the character and appearance of the Island. Recent development has often been criticised for its similarity to developments across the Island and elsewhere - "anywhere" architecture. At the same time some criticise current practice to retain traditional or vernacular designs. As is often the case the truth lies somewhere between the two extremes. All too often proposals for new developments have not taken into account a proper analysis of their context in terms of siting, layout, scale, materials and other factors. At the same time a slavish following of past design idioms, evolved for earlier lifestyles can produce buildings which do not reflect twenty first century lifestyles including accessibility and energy conservation. While there is often a consensus about what constitutes good and poor design, it is notoriously difficult to define or prescribe. 4.3.9 The Department recognises the need to raise the quality of the Island's architecture and built environment and is pursuing this through the development control process and the commissioning of its own schemes and environmental improvements. At the same ti me it appreciates that the debate about good design needs to be broadened to include those who design, construct and finance new development and the wider community as we are all affected by the end product. To this end it welcomes the Isle of Man Arts Co uncil's National Arts Development Strategy 2005 - 2014 which has as one of its objectives, to raise the quality of the Island's architecture and built environment by encouraging debate on architectural standards, town and country planning, urban regenerati on and public art. This Strategy recognises that debate will have to take place over time. 4.3.10 In the meantime, the Department considers that, while there are a number of policies in the Strategic Plan which cover various elements of the design of new development e.g. General Policy 2 (a) -(i), ( m) and (n), and various Housing policies, there is a need for a further statement on the need to secure quality in the design of new development. In the preparation of Area Plans the Department will include development briefs that set out design principles for significant sites including new residential areas. Subsequent planning applications will be required to be accompanied by a Design Statement setting out the way in which the proposal has been designed to take into account its context and how the design principles have been developed. 4.3.11 At the same time as wishing to promote good design in new development the Department recognises that there are an increasing number of alternative styles of housing which draw their design principles from the wish to promote sustainability and energy efficiency. Many of these can be incorporated into both modern and traditional designs but in some cases they produce a completely different structure or form of buildings, for exa mple underground (1)Registered Building is defined in Appendix 1 (2) Conservation Area is defined in Appendix 1 housing. While wishing to conserve the historic landscape of the Island the Department welcomes new styles of housing as long as they take into account the landscape context and the impact on the amenities of the area in which they are si ted. Merely arguing that a new building cannot be seen in public views is not a justification for the relaxation of other policies relating to the location of new development.
Environment Policy 1
Area Plan for the East sets out locally-applicable means for implementing the policies set out in the Isle of Man Strategic Plan 2016. In that Strategic Plan, we find the Environment Policies. Environment Policy 1 states: The countryside and its ecology will be protected for its own sake. For the purposes of this policy, the countryside comprises all land which is outside the settlements defined in Appendix 3 at A.3.6 or which is not designated for future development on an Area Plan. Development which would adversely affect the countryside will not be permitted unless there is an over- riding national need in land use planning terms which outweighs the requirement to protect these areas and for which there is no reasonable and acceptable alternative. Maintaining the purpose of this Area Plan as a means of implementation, there is some further direction to be found in the Strategic Plan, at paragraph 7.2.1: 'Whilst landscape and coastal change is inevitable, and in some cases desirable, the emphasis must be on the appropriateness of this change and the balance or equity between the needs of conservation and those of development. The primary goal must therefore be to respect, maintain and enhance the natural and cultural environment including nature conservation and landscape and coastal quality, and ensure its protection from inappropriate development.' Given the comprehensive nature of the Isle of Man Strategic Plan's Environmental Policies, only a small number of additional Proposals and Recommendations are necessary. In order to produce an implementable Area Plan for the East it is necessary to recognise those statutory desig nations and strategies which whilst having an Island-wide scope are highly relevant to the protection of environments within the Plan Area. An example is the UNESCO Biosphere status afforded to the Isle of Man. Island-level strategies identify crossborder issues and take account of the cumulative impacts of human engagement with nature. Area Plan Objectives i. To protect, conserve and enhance the natural and cultural environment of the plan area and promote biodiversity. ii. To improve the function, usability and provision of our green infrastructure and public spaces by providing a network of green spaces and features which are connected and where possible, accessible to the public. iii. To manage and improve flood risk and improve drainage conditions. iv. To support the working countryside and its custodians in maintaini ng a sustainable rural economy. Area Plan Desired Outcomes i. Where approved, d evelopment will be ecologically sustainable and designed to protect and where possible enhance biodiversity as well as mitigate and adapt to the effects of climate change. ii. The Green Infrastructure network will be established and fostered, connecting people with nature in a way that achieves the best shared outcomes for the urban and natural environment. iii. Statutory and non-statutory designations will continue to provide protection to the most important and most vulnerable cultural assets, habitats and environments in the plan area. iv. Beyond the towns and villages, the area as a whole will retain its landscape setting including its important visual interaction with the central uplands, central valley, coast and marine environment. Natural Environment Proposal 1 The Department supports the protection, creation and improvement of green infrastructure in the East, particularly in those locations which have the potential to be part of a Green Infrastructure Network. Applications for development must take into account any approved Government Green Infrastructure Strategies, but in any case, must identify how development proposals intend to contribute to the long term provision of a network of connected green spaces. UNESCO Biosphere In 2017, the Isle of Man became the first ever entire nation to achieve UNESCO Biosphere status. Project partners pledge to take steps to protect natural resources, develop the economy in a sustainable way and promote outstanding living landscapes. UNESCO Biosphere Reserves are established to connect people and the economy with nature, wildlife, culture, heritage and communities. Biosphere Reserves have three functions: Conservation: to contribute to the conservation of landscapes, ecosystems, species and genetic variation. Development: to foster economic and human development which is socio -culturally and ecologically sustainable. Logistic support: to support demonstration projects, environmental education and training, research and monitoring related to local, regional, national and global issues of conservation and sustainable development. The Isle of Man Biosphere is zoned into six areas . Examples of all of these can be found in the Eastern area: Terrestrial Core areas, Marine Core areas, Terrestrial Buffer zone, Marine Buffer zone, Terrestrial Transition areas and Marine Transition areas. There is some overlap with The Isle of Man's First Biodiversity Strategy 2015-20

d/Governor 's Road junction. Any future applications will be considered on their merits taking into account the proposals set out in this plan and the Strategic Plan (see Maps 3 and 6). Natural Environment Proposal 2 (Green Gap) Between the settlements of Douglas and Onchan in the area straddling Blackberry Lane, development which would erode the separation and detract from the openness between the settlements will not normally be supported. Applications may be considered favourably if reason for an exception can be demonstrated in line with General Policy 3(g). Laxey and Baldrine - Encroaching ribbon development along the A2 C oast Road which connects Laxey and Baldrine has the potential to connect the two settlements. At present this area largely retains its sense of being in the open countryside with clear sea views. Additionally, services for networked water supply and other essential utilities would be difficult to provide for additional development in this area (see Maps 3, 7 and 9). Natural Environment Proposal 3 (Green Gap) Between the settlements of Laxey and Baldrine, development which would erode the separation and detract from the openness between the settlements will not be supported. Glen Vine and Crosby - These two settlements, although proximate in location, are separate and distinct in many ways. Consultation has clearly demonstrated this through the views expressed during the stages of plan development. In cases such as this, the breaks in the urban fabric and the features of nature which provide a sense of openness should be protected from development which would erode this (see Maps 3 and 10). Natural Environment Proposal 4 (Green Gap) Between the settlements of Glen Vine and Crosby, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. Douglas, Union Mills and Strang (see Maps 3, 4 and 8) Natural Environment Proposal 5 (Green Gap) Between the settlements of and Douglas, Union Mills and Strang, development which would erode the separation and detract from the openness between the settlements is unlikely to be supported. The Upland Environment The Manx Uplands are an iconic part of our landscape and heritage. Reference to the 'sweet mountain air' and 'green hills and rocks' are enshrined in our national anthem and the colours of the heather and gorse are woven into the very fabric of Manx tartan. The hills are a place of great beauty, yet for some they are also a place to work and for others a place to exercise or simply enjoy open space. Our Uplands are also home to plants and animals that whilst familiar to us, are rare and impor tant in a global and European context. Furthermore, the uplands are a rich repository of cultural and archaeological remains, which are sensitive to change and can easily be damaged by inappropriate development. Production of food is an important and obvi ous function of hill land. But surprisingly, the Manx hills provide everyday functions that most people take for granted. Peatlands, which cover most of our hills reduce the impacts of climate change by locking up carbon dioxide, collect and filter our drinking water and slow the passage of rainfall into streams and rivers, thus reducing downstream flood risk. These multiple uses are of great benefit to the economy of the Isle of Man and the well - being of its people. It is important that the hills continue to provide these benefits long into the future. Ensuring sustainable management of such a wide range of uses to the satisfaction of all interested parties whilst retaining functions essential to the well -being of the Isle of Man is of paramount importance. The Isle of Man Government is the owner and landlord for the majority of the Uplands in the East region and is therefore in a position to implement policy which will deliver the optimum range of ecosystem services. Appropriate and positive Upland management such as controlled rotational burning/cutting of heather and low intensity grazing helps to reduce the fuel load of the hill, provides firebreaks and reduces the risk of unplanned wildfires that further protects the biodiversity of the site, but also the vast amounts of carbon locked away in the peat soils. The majority of this work is carried out by The Department of Environment, Food & Agriculture's grazing and shooting tenants. The Manx Uplands are critically important from a habitat and biodiversity perspective. The hills in the East support a significant number of breeding hen harriers; however, other native Upland breeding birds such as curlew and red grouse have suffered severe declines in recent decades and as such are of high conservation concern. Strict control of access and recreational activity on vulnerable soils should be implemented to reduce soil erosion and subsequent carbon loss. Curlew and hen harriers are recognised as an internationally important species, while (within the EU) upland heather moorland is designated

Baffling and directionality of lighting must be sensitive to contain any necessary lighting within a subject site only. Watercourses and Wetlands The collection of hills in the East has produced a network of mountain streams which gradually join and widen to become the rivers flowing out into Douglas Bay, Port Groudle and Laxey Bay. Several of these rivers fro m the natural boundaries between the Eastern Parishes. A non-exhaustive list of streams and rivers in the East includes: Crammag River Injebreck River Creg-y-Cowin River West Baldwin River Awin Ny Darragh Baldwin River River Glass Greeba River River Dhoo Santon Burn Crogga River Middle River Laxey River Glenroy River Groudle River Ballacottier River River Douglas It is likely that these streams and rivers, similar to most of the Island's watercourses, support populations of European Eels - classified by the International Union for the Conservation of Nature (IUCN) as Critically Endangered - and Brown Trout. Most rivers with good fish passage from the sea, including the Dhoo, Glass, Laxey and Santon Burn, contain populations of salmon and sea trout. The Dhoo and Glass are known also to support populations of brook (and possibly river) lamprey. Many of the tributary streams to the major rivers, although small, provide valuable additional spawning and nursery areas for salmonids and lampreys. There are four reservoirs in the East: Eairy Dam, Injebreck, Clypse and Kerrowdhoo. The proposals in this plan for additional housing in the East are likely to have an impact on the water levels in these reservoirs and consequently on the compensation flows within the downstream rivers. DEFA reports that i n recent years there has been evidence of low summer flow below Injebreck reservoir in the River Glass. It is suggested that any reduction in flow in the River Glass could have consequences for the ecology of the river, including fish populations. DEFA has highlighted evidence that artificial light from new housing close to rivers may have a detrimental impact on migratory salmonids. The reservoirs in the East are home to wild brown trout and Injebreck, Clypse and Kerrowdhoo are stocked with rainbow trout for visiting anglers. This Plan recognises that the economic value of the recreational fishing industry depends both on healthy fish stocks and high recreation and visual amenity. The ecological services provided by the Island's watercourses and wetlands are considerable, including carbon storage and natural flood mitigation. An undeveloped corridor of land between the river bank (measured from the edge of th e river channel) and any riverside development is required to allow for natural changes in the position of the river channel, as well as in water levels . The natural vegetation and physical structure of a river bank also provides a wildlife corridor for non-aquatic species. Natural Environment Proposal 8 Proposals for new development in the Plan Area which intend a connection to the Injebreck Reservoir for its water supply must demonstrate that as a consequence of this new development, water levels will n ot be so affected as to have a detrimental effect on normal flows. Natural Environment Recommendation 2 It is recommended that ahead of making any applications for development close to the reservoirs, watercourses and wetlands in the East, applicants must discuss such proposals with DEFA to establish the need for specific design elements to be taken into account . This may include : the impact of artificial light from the development on migratory fish species, buffer distances from the river bank and visual amenity. Marine Protected Areas and Marine Conservation Zones Increased efforts are being made to protect the health and biodiversity of the marine environment as well as the economic and social benefits which effective management of marine resources brings. Marine protected areas are areas of the sea that are protected from fishing and other impacts, with the aim of restoring habitats and supporting sustainable fisheries. The Isle of Man currently has ten Marine Protected Areas around our coast, encompassing 10.4% of Manx waters. One of these is the Sea Fisheries Restricted Area at Laxey Bay which was established in 2009 with the intention of enh ancing the scallop stock and later seeded with juvenile scallops. In 2008 , Douglas Bay closed to mobile fishing gear. Its current status is as a Marine Conservation Zone, though there is an intention to designate the Bay as a Marine Nature Reserve. Marine Nature Reserves are designated to conserve their flora,
Environment Policy 22
Environment Policy 22: Development will not be permitted where it would unacceptably harm the environment and/or the amenity of nearby properties in terms of: i) pollution of sea, surface water or groundwater; ii) emissions of airborne pollutants; and iii) vibration, odour, noise or light pollution. 7.17.2 In addition to the above, changes in the activities associated with the current permitted use of land or a building, which in themselves do not constitute development and therefore do not require planning permission, can have an adverse impact on adjacent properties by virtue of noise, light or general disturbance. For example the addition of security lig hting on a property may cause light pollution affecting adjacent properties and the wider area. The introduction of new activities into established parks and recreation areas can have an impact on neighbours. In such cases the Department would advocate t he person or organisation considering the change to give careful consideration to the potential impact of such activity in terms of location, siting and design.
Environment Policy 28
Environment Policy 28: Development which would be at risk from ground instability or which would increase the risk from ground instability elsewhere will not be permitted unless approp riate precautions have been taken. 7.23 Consultation Zones for Hazardous Installations 7.23.1 There are a number of installations on the Island that represent a constraint on development in the vicinity because of health and safety considerations. Such installations are essential Island facilities such as the petroleum and LPG storage at Douglas Harbour. The type of constraint posed to development varies by facility and therefore there will be a need for the Department to consult with the Health and Saf ety at Work Inspectorate regarding any development within such zones.
