NON TECHNICAL SUMMARY INTRODUCTION Veolia E S Leeds Ltd (‘VESL’) intends to construct a Recycling and Energy Recovery Facility (RERF) to serve the administrative area of Leeds City Council. The RERF will be fired predominantly by residual municipal waste and a small amount of commercial and industrial waste of similar characteristics as municipal waste. With a design capacity of 214,000 tonnes of waste per annum(1).(214,000 tonnes per annum MPT and 164,000 tonnes per annum ERF), the RERF will be operated by VESL, a wholly owned subsidiary of VESUK. In addition to dealing with waste, the Recycling and Energy Recovery Facility can generate approximately 11 MW of electricity to be exported to the local electricity network via an underground cable. This Non-Technical Summary is provided as a condensed summary of the key assessments and results submitted as part of the Application for a new permit under the Environmental Permitting (England and Wales) Regulations 2010 (the “EP Regulations”), Statutory Instrument 2010 no. 675. BACKGROUND Description of Waste and Regional Context Leeds City Council has a responsibility for collecting and disposing municipal waste. It mainly comprises: wastes produced by householders; wastes produced by trade premises that are collected by LCC; and litter and street sweepings. The need for a facility to divert waste from landfill has been established through the local response to national waste management targets and regional drivers. Such a facility was sought to ensure that there will be a minimal regional and local requirement for landfilling of residual municipal waste, but also to increase the level of recycling in the City. A full demonstration of the need for the facility is included in the Supporting Statement of the Planning Application. -1.

ENVIRONMENTAL RESOURCES MANAGEMENT VEOLIA ES LEEDS LTD I Leeds Waste Management PFI Contract In 2007 Leeds City Council submitted ‘The Residual Waste Treatment Project: Outline Business Case’ to DEFRA to apply for Private Finance Initiative (PFI) Credits. The Project has secured PFI Credits to the value of £68.6 million. Consequently, LCC expects to enter into a 25 year contract with VESL in Summer 2012 The PFI is a form of public-private partnership (PPP) in which local authorities can gain access to new or improved capital assets. Unlike traditional procurement the public sector does not buy the assets, but rather pays for their use. The overarching objectives of the Leeds PFI Contract are to: deliver the proposed RERF at Cross Green Industrial Park in accordance with the Project Agreement; meet the Contract Waste Diversion Targets; use and promote the principles of the Waste Hierarchy, i.e. promote waste prevention, minimisation and re-use through increased public awareness, education and involvement in the management of waste; and encourage and promote partnering between VESL and LCC to facilitate continuous improvement of service delivery. The Proposed Recycling and Energy Recovery Facility Residual municipal waste collected from within the administrative area of Leeds City Council will be sent to the RERF with a small amount of waste being accepted from outside Leeds to accommodate contract requirements. See Table 7.1 of Volume 2 for a detailed list of wastes accepted at the RERF. The RERF comprising a Mechanical Pre-Treatment (MPT) process with a capacity of 214,000 tonnes per annum for the further recovery of recyclables from incoming wastes and a subsequent Energy Recovery Facility (ERF) for the treatment of the remaining waste fraction with a capacity of 164,000 tonnes per annum(1) (see Figure 7.1 of Volume 2). The MPT process will utilise front-end pre-treatment equipment which is designed to beneficially remove a minimum of 10% and up to a potential maximum of 20% (depending on feedstock make-up) of the overall RERF input for recycling, adding approximately 5% to the LCC's recycling rate. Anticipated recyclates are plastic, metals and fibre (paper and card). -1. (1) based on an average of 8,000 hours of operation and an average Calorific Value of 9 MJ kg The maximum theoretical annual capacity is 179,580 tonnes based on 8,760 hours of operation. ENVIRONMENTAL RESOURCES MANAGEMENT VEOLIA ES LEEDS LTD II The 164,000 tonne per annum (1) ERF will convert the remaining residual waste into electrical power through the use of modern, high efficiency incineration. Approximately 11 MW of energy will be exported into the local electricity distribution network, which is sufficient to supply the equivalent of around 20,000 homes. The RERF will be classified as a “recovery” operation as defined by the Waste Framework Directive 2008/98/EC, Annex 2, R1 formula. The plant has also been designed to be CHP ready and opportunities to link the ERF to CHP users in the Aire Valley and towards the Leeds City Centre are being investigated. Remaining ferrous metals will be separated from the bottom ash and sent to market. Bottom ash will also be recycled off-site for beneficial use as opposed to landfill disposal. Flue Gas Treatment (FGT) residues from the ERF will be disposed of in an appropriate permitted facility. A section of the RERF will also have the ability to function as a transfer station. This would only be the case under specific conditions such as a breakdown, malfunction or maintenance of the MPT or the ERF or if the waste cannot be treated at the site for quality reasons and requires to be transferred out for treatment at a suitable permitted facility. SITE CONDITION REPORT (VOLUME 2, SECTION 3 AND VOLUME 3, ANNEX A) An Application Site Condition Report (SCR) has been compiled following Environment Agency guidance. This document is included in Annex A. Information regarding the site and surrounding areas has been reviewed in order to describe the condition of the site and, in particular, to identify any substance in, on, or under the land that may constitute a potential pollution risk to the land. Pollution prevention measures have been identified and an assessment of pollution potential to land has been undertaken. PROPOSED ACTIVITIES (VOLUME 2, SECTION 4) Outline Design and Process Description The RERF will consist of a Mechanical Pre-Treatment (MPT) process for the further recovery of recyclables from incoming residual wastes and an Energy Recovery Facility (ERF) for the remaining residual waste fraction. The MPT process will be designed to beneficially recover further recyclable materials from the incoming waste. The remaining wastes will then move on to the ERF. The ERF will consist of a single stream with a capacity of 20.5 tonnes of residual municipal waste per hour. Figure 1 shows the stages in the MPT Process, and Figure 2 details the process steps of the ERF. Waste is combusted, and the heat from this process is used to heat water to steam in (1) based on an average of 8,000 hours of operation and an average Calorific Value of 9 MJ kg-1. The maximum theoretical annual capacity is 179,580 tonnes based on 8,760 hours of operation. ENVIRONMENTAL RESOURCES MANAGEMENT VEOLIA ES LEEDS LTD III the boiler. The steam from the boiler is then routed to a turbine to generate electricity. The output steam from the turbine is then cooled, and converted back into water to be recycled back into the boiler. The RERF is designed to produce approximately 11 MW of exportable electricity. The activities carried out at the RERF will comply with the Waste Incineration Directive (WID).

The acid gases generated by the combustion of waste will ENVIRONMENTAL RESOURCES MANAGEMENT VEOLIA ES LEEDS LTD IV be neutralised and the resulting particulate matter separated out in a bag filter. Emissions of nitrogen oxides will also be reduced, through the use of a Selective Non-Catalytic Reduction (SNCR) de-NOx treatment. In addition to process logic controllers, the Facility also utilises various process control and monitoring mechanisms to minimise emissions to air.
