Policy DM34- Minerals Area of Search (2019 Update) Site 1: Land at Dewley Hill, Ponteland Road, north of Throckley Fig 1: Site Location Plan Description The area is located approximately 8km west of Newcastle. The site lies to the north of the A69 highway, east of Ponteland Road and west of North Walbottle. It lies wholly within the area of Newcastle. However, it is adjacent to the city’s boundary with Northumberland. Ponteland Road, which runs along the sites western boundary, falls largely within Northumberland. The site covers approximately 110 50 hectares in area. The site is in a rural area of the urban fringe and forms part of the Tyne and Wear 1 Green Belt. The site is currently in agricultural land, split into a series of green fields separated by hedgerows. There are a number of individual and small terrace of houses dispersed around the edge of the site. The nearest individual properties to the site are Callerton Lane Cottages, Dewley Farm, Crescent Farm, Lough House and Field House. Throckley is located to the south of the A69 with properties along the northern edge benefitting from distant views of the area. Land to the immediate south east of the site, which was formerly Green Belt, has been allocated in the Core Strategy and urban Core Plan for housing development at Lower Callerton under Polices CS3 and NN1. Geology The site lies on Carboniferous (Westphalias B) Middle Coal measures strata, comprising of mudstones, siltstones, sandstones, coals and seat earth. There are several coal seams present which run in a south easterly direction including, the Top Plessey, Bottom Plessey, Harvey Main, Penny Hill, Harvey, Hodge, Tilley, Top Busty, Bottom busty, Threequater, Top Brockwell, Top Victoria, Bottom Victoria and Bottom Marshall (in sequence of encountered). A large fault zone is present through the site running SW – NE and down through the strata to the north west by 20-40 metres. The coal at Dewley Hill is understood to be of high quality, being low in chlorine, sulphur and ash content. It is anticipated that approximately 800,000 tonnes of coal could be available for extraction at the site. A larger resource may also be available on land surrounding the proposed site, however, there are various environmental constraints that would preclude such extraction. In addition to coal, there is also potential for a significant amount of fireclay to be recovered from the Dewley Hill site. The site has been subject to past coal mining activity and is located within an area of surface coal resource. Within the site are 25 recorded mine entries with a further 2 mine entries within influencing distance of the site. The site contains recorded coal workings in 8 seams from shallow depth to 149 metres. In addition, the site contains recorded thick coal outcrops and unrecorded, probably underground, coal workings at a shallow depth. The historic coal mining legacy features could potentially pose a risk to new development and will need to be considered as part of any future application for extraction of minerals. Constraints The site is within the Tyne and Wear Green Belt, is highly prominent from a number of main access roads into the city, most notably the A69(T) to the south,B6323 (Ponteland Road) and B6324 (Stamfordham Road) and from a number of local recreation routes, falls within the setting of a number of heritage assets and forms part of a wider wildlife and green infrastructure enhancement corridors (see figure 2) 2 Fig 2. Constraints Plan Ecology The site forms part of a Wildlife Enhancement Corridor identified under DAP Policy DM29 and within Core Strategy Policy CS16, linking south to Throckley Dene and north east as part of the Ouseburn/Walbottle Dene and Black Callerton Wildlife Corridors. Callerton Pond Local Reserve is located to the immediate north east of the site and Throckley/Walbottle Dene Local Nature reserve and Local Wildlife Site (LWS) is located south of the A69 to the south of the site. The site consists of a series of fields bounded by hedgerow boundaries interspersed with some trees. The ecological value of the site is considered average due to the limited vegetation and habitat. The most important feature is the Dewley Burn which lies to the southern part of the site connecting with Throckley/Walbottle Dene. The main species potentially affected by the minerals development on this site are winter/breeding birds, otters and water vole, bats and other protected species. Initial surveys undertaken by Banks Mining Ltd as part of a scoping exercise have found two potential otter holts. In addition the site provides habitat for several bird species of conservation value including Linnet, Northern Lapwing, Short-eared owl, Skylark, Song thrush, Redwing, Starling, Tree Sparrow, Yellow Tit and Yellowhammer. Archaeology/Historic Environment Impact Extraction of minerals in this location could potentially have an impact upon a 3 number of heritage assets and their settings within a 2km area around the site. These include:- • Hadrian’s Wall World Heritage Site (HA 1000098 and HA 1010616) • Dewley Hill Round Barrow (HA 108678), a scheduled ancient monument (SAM) • Round cairn at Heddon Laws Farm (HA 1015846) • Coal workings at Dewley Pit (HA 10106194), also a SAM. • Northumberland Gardens Conservation Area (located within Newcastle boundary) These assets could affect the extent of coal extraction in this location, as evidenced by previous refusals of planning permission to work this area. Consideration of the impact on the setting of heritage assets will need to be assessed as part of any planning application submission. Landscape Character The Council’s Character Assessment (2017) is a city wide visual assessment of the character of defined areas, identifying positive and negative aspects, including any features that are very special, unusual, distinctive or unique. The sites falls within Landscape and Townscape Character Zone B: Callerton Basin. This zone is very strongly agricultural in character, with numerous small hillocks and undulations that often indicate historic mining activity. The countryside character with a patchwork of fields that has a rural charm. Tree cover is generally sparse though there are a number of hedgerows trees. The Dewley Hill site falls within four chartcer areas: B50- Ouseburn head; B51 Crescent Farm; B52 Fell House Farm and B62 Dewley Farm. The character generally comprises of a gently rolling agricultural landscape with informal field patterns. Where hedges exist on the site they often contain gaps, with some sections completely removed. A small number of hedgerow trees are also present on the site. The historic County boundary hedge runs north –south through the site and is of ecological, historic and visual value. The site falls within the Tyne and Wear Green Belt, as defined by Policy CS19 of the CSUCP, which also sets out the reasons for including this area as Green Belt. Paragraph 146 of the NPPF sets out that mineral extraction is not inappropriate within the Green Belt provided it preserves its openness and does not conflict with the purposes of including land within it. Any application for mineral extraction on this site would therefore need to demonstrate compliance with this paragraph within the NPPF and Policy CS19. The site is highly visible from traffic passing along the A69(T) to the south, B6323 (Ponteland Road) and B6324 (Stamfordham Road) to the north and from a number of local recreation routes, with longer distance views from North Walbottle Road to the east and Northumberland Gardens Conservation Area. The visual impact of mineral extraction from these roads and recreational routes, upon the landscape character of the area and any associated cumulative affects is therefore potentially a significant impact that would need to be tested as part of any 4 application. Accessibility Proposed access to the site would be from Ponteland Road to the western boundary of the site. The area is crossed by public rights of way and there are also some rights of way adjacent the site. Mineral extraction on this site would require the temporary diversion of the existing rights of way network during site operations, as well as impacting upon the users of adjacent rights of way network. Flood Risk The site falls within the joint catchment for the Dewley Burn and the Ouseburn. It is largely within Flood Risk Zone 1 and within the Council’s designated Critical Drainage Area. The potential impact of any extraction proposals on the watercourses on site and other hydrological assets will need to be considered as part of any application for extraction of minerals from this area. Aviation Safety The site is located to the south west of Newcastle International Airport, within the Inner Horizontal Surface and Conical Surface of the aerodrome, which are protected surfaces and required to ensure that aircraft can safely transit through the airspace without any physical obstruction. The impact of any proposed minerals extraction operations, including dust and particle emissions from blasting and lighting and also the site restoration, including any new land forms penetrating from the protected surfaces and introduction of significant habitat creation for birds or the creation of additional food sources which could lead to bird strike hazard, would need to be fully assessed as part of any planning application. Noise, Dust, Vibration, Light Pollution and Residential Outlook Due to the close proximity of a number of residential properties around the periphery of the site and proposed future housing as identified in the Core Strategy, mineral extraction has the potential to generate noise, dust, vibration, light pollution which, if unmitigated, could impact upon the amenity and health of the occupants of neighbouring properties. In addition, the outlook from a number of residential properties that are located close to the site boundary, including future housing sites, will also need to be tested to ensure it would not unacceptable affect local amenities and the use of land and buildings which ought to be protected in the public interest.
