It assesses the potential direct and indirect impacts of development proposed at the site of the former Varteg Hill Colliery, to the West of Varteg Road, Varteg, Pontypool, on the setting of the Blaenavon Registered Landscape of Outstanding Historic Interest and four of its associated Historic Landscape Character Areas (HLCAs) and the Blaenavon Industrial Landscape World Heritage Site (BILWHS). The proposed development site lies partly within one HLCA of the Registered Landscape, and the BILWHS, giving rise to the potential for both direct and indirect impacts. The development site is divided into two areas, the eastern to be the focus for removal of existing vestiges of historical coal mining and new extraction, and the western designed to be used for overburden deposition. It is considered that the direct impacts in the western part of the site, where approximately 20ha lie within the Registered Landscape area, will be minimal, as the existing character of the site would not be fundamentally altered, as it has already been subject to deposition and landscaping in this area. It is considered that direct physical effects in the eastern part will be limited to the small (less than 1ha) area on the edge of HLCA 020 which will be removed during the mining process. The limited loss of non-designated heritage assets here could only have a very small effect on the overall heritage value of the HLCA and the Registered Landscape as a whole. An indirect physical effect has been identified in this eastern area, namely the loss of the western end of the Varteg Colliery Incline, which links the colliery area with the bottom of the Lwyd valley to the east. While this physical link will not be broken or lost entirely, it would be partly reduced by the development. While this is an impact of some significance, in the overall context of the Registered Landscape area, it is not such that it would materially reduce the significance of the landscape. The indirect impacts on views out of the four HLCAs which are closest to the development site have been assessed as also of limited effect. The peripheral location of the site on the west side of the Lwyd valley, where it does not have any visual interaction with the core heritage assets of Blaenavon, means that the changes within the site would not have a substantial impact on the overall setting of the Registered Landscape. Impacts are limited to small areas of the surrounding HLCAs. While the development would remove existing features in the historic landscape, it would not introduce and jarring or novel elements to the residual © CgMs Limited PB/17673 Varteg Coal Reclamation Project – Historic Landscape Impact ASIDOHL2 Assessment landscape, and as such the overall effect of the development would not alter the fundamental character or significance of the Registered Landscape as a whole. © CgMs Limited PB/17673 Varteg Coal Reclamation Project – Historic Landscape Impact ASIDOHL2 Assessment 1.0 INTRODUCTION AND SCOPE OF STUDY 1.1 Introduction 1.1.1 This assessment has been undertaken to assess the nature and significance of effect on the Cultural Heritage Resource of the proposed coal reclamation project on the site of the former Varteg Colliery, Varteg, Pontypool, South Wales. The Proposed Development 1.1.2 The proposed development encompasses approximately 60ha of land on Varteg Hill, off Varteg Road, Varteg. A planning application has been submitted to Torfaen County Borough Council (ref. 14/P/00290) for the excavation of coal and reclamation of the site. 1.1.3 The proposed development lies partly within the Blaenavon Industrial Landscape World Heritage Site (WHS) and within the Blaenavon Landscape Area on the Register of Landscapes of Outstanding Historic Interest in Wales. 1.2 Purpose of Assessment 1.2.1 The main objective of the assessment has been to identify the known elements of the cultural heritage resource that may be affected by the proposed development and to determine the importance of those resources so that the significance of the likely effects of the development can be established. The scope of the resource considered by the assessment has therefore included all known archaeological sites, areas of archaeological potential, World Heritage Sites, Listed Buildings (LBs) and non-listed buildings of architectural or historical value, Scheduled Monuments (SMs), Conservation Areas, and Registered Landscapes of Historic Interest in Wales. 1.3 Assessment Methodology 1.3.1 The ASIDOHL2 methodology is set out in Guide to Good Practice on Using the Register of Historic Landscapes of Historic Interest in Wales in the Planning and Development Process – Technical Annex, 2nd Edition (Cadw, Welsh Assembly Government. 2007). It is based on the use of identified and described Historic Character Areas within a Registered Landscape. 1.3.2 It comprises the following five stages: Stage 1 – Compilation of an introduction of essential, contextual information; © CgMs Limited PB/17673 Varteg Coal Reclamation Project – Historic Landscape Impact ASIDOHL2 Assessment Stage 2 – Description and quantification of the direct, physical impacts of the development on the Historic Character Area(s) affected. Stage 3 – Description and quantification of the indirect impacts of development on the Historic Character Area(s) affected. Stage 4 – Evaluation of the relative importance of the Historic Character Area(s) or part(s) thereof directly and/or indirectly affected by the development in relation to: o the whole of the Historic Character Area(s) concerned, and/or o the whole of the historic landscape area on the register, followed by o an evaluation of the relative importance of the Historic Character Area(s) concerned in the national context, and a determination of the average overall value of all of the Historic Character Areas (or parts thereof) affected. Stage 5 – assessment of the overall significance of impact of the development, and the effects that altering the Historic Character Area(s) concerned has on the whole of the historic landscape area on the register. 1.4 Register of Historic Landscapes in Wales 1.4.1 The register of Landscapes of Historic Interest in Wales was published in 1998 and 2001, and the Historic Landscape Character Areas for the Blaenavon Landscape Area have been defined by the Historic Landscape Characterisation undertaken by Glamorgan-Gwent Archaeological Trust in
