**Document:** Billown Quarry Site Report **Application:** 22/00922/B — Restoration of quarry by infill **Decision:** Permitted **Decision Date:** 2023-12-06 **Parish:** Malew **Document Type:** report / planning_statement **Source:** https://planningportal.im/a/9566-malew-billown-quarry/documents/1569789 --- # Billown Quarry Site Report ## 4.0 Site Report The application must be accompanied by a (Baseline) Site Condition Report, which describes the condition of the whole site, not just the landfill. Operators are required in particular to “identify any substances in, on, or under land which may constitute a pollution risk” This Site Report gives a factual “baseline” account of the land. ## 4.1 Introduction and Background InformationSite details The site entrance is located at National Grid Reference (NGR) SC 27041 69956, the centre of the site is at SC 26694 70114, which lies approximately west of Ballasala, east of Ballabeg and north of Castletwon. The site is off the A3. The site is an operational quarry. The site is surrounded with large areas of agricultural land and the A3 is to the east of the site. Access to the site is directly off the A3 through lockable steel security gates. The landfill site covers an area of approximately 75,000m2 with a capacity of 1,000,000m3. The boundary includes all of the area for the inert landfill. The permit area is coloured in yellow on ESSD 2. Outline of proposed development This includes details relating to the following. - • The proposed waste types for the landfill area be inert non-reactive wastes. - • A skip will be located on site for load rejection. - • The site will have 2 operational phases to complete the landfill final landform. The time taken lining, infilling and restoration is 43 years. - • The site will have a valid planning permission. The layout of the site is presented at Drawing ESSD 4. - • The final landform and end use is to be agricultural land. - • The site permit boundary requires an engineered geological barrier for all landfill areas. - • The site is not within an SPZ. ## Any former land-uses that may give rise to potential sources of nonlandfill related contamination Based on the site investigations and historical research there are no former landfill operation located in the landfill site but areas adjacenet were used for landfill in the past. It is therefore reasonable to conclude that the site has considerable influence from around the perimeter of the site, currently and historically. ## Sources of Information - i. DEFA; - ii. The British Geological Survey records and publications; - iii. The Ordnance Survey. Geology and hydrogeology The Billown Quarry Landfill is located in the Carboniferous limestone. Groundwater monitoring of levels will be undertaken. DEFA has confirmed that the site is not within an SPZ. Archive search and land-use chronology The site has been used as quarry. Relevant information relating to potential contaminants Groundwater datasets suggest that former landfilling has not impacted on groundwater quality. Any history of incidents There are no records of pollution incidents relating to this facility - 4.2 Objectives of this Assessment Context within Waste Disposal Licence Monitoring records for the site have been assessed together with site investigations to define the initial site conditions and to allow for baselines to be set and for action and trigger levels to be set for groundwater, leachate, landfill gas and particulate matter. ## Description of general approach The Environment Agency Template has been used for the “Conceptual Model, Environmental Setting and Site Design” section of the Environmental Permit application for the landfill has been used. It has been designed to describe the conceptual model and setting for the site. The conceptual model has provided an understanding of the installation in its environmental setting and consideration of the design and operation of the site at the time of the application. This report addresses the source terms of the risk (i.e. waste), all pathways and receptors and has been used as a basis for commencing the risk assessments. The final conceptual model report has been prepared on the basis of the findings of the component risk assessments (e.g. hydrogeology, stability, landfill gas, nuisance and amenity) required under this WDL Application. Different types of contaminants to be considered The site will accept inert waste. The site area requires the construction of an engineered artificial geological barrier using clay type materials to the base and sides to achieve a minimum target permeability of 1 x 10-7m/s. - 4.3 Site Investigation (Data Collection) Details Description of site investigation and related work activities. Specific site investigations have been carried out with regard to the local hydrogeology of the site. As part of these site investigations, boreholes will be drilled and borehole logs produced at each stage. ## Description of laboratory analysis This includes permeability of the soil, groundwater quality, groundwater levels, site levels, gas concentrations outside the site, and former testing including drawdown groundwater impact, river flow and hydraulic conductivity testing and falling heads tests ## 4.4 Summary of Site Investigation and Analysis FindingsOn-site observations Physical observations of the base and sides of the quarry site have been observed during walk over surveys. Monitoring data This includes, groundwater level monitoring, groundwater quality testing, permeability testing of the site, noise monitoring, landfill gas monitoring. ## 4.5 Data Interpretation Proposal of ‘baseline’ conditions for the site. Control and trigger levels for the groundwater are set in the HRA, LFGRA and SRA. ## 4.6 Conclusions The Billown Quarry landfill site to be operated as an inert landfill site, with the inert wastes deposited into engineered cells. The site is to have an engineered Geological Barrier constructed under an approved CQA regime. The site is to be operated under a Waste Disposal Licence issued under the Public Health Act 1990. --- *Data sourced from the Isle of Man public planning register under the [Isle of Man Open Government Licence](https://www.gov.im/about-this-site/open-government-licence/).* *Canonical page: https://planningportal.im/a/9566-malew-billown-quarry/documents/1569789*
