Determination of an Application for an Environmental Permit under the Environmental Permitting (England & Wales) Regulations 2010

Consultation on our decision document recording our decision-making process

The Permit Number is: EPR/TP3036KB The Applicant / Operator is: Biffa Waste Services Limited

The Installation is located at: Newhurst Quarry Shepshed Leicestershire LE12 9BU Draft For Consultation commences on: 2 March 2011 Consultation ends on: 31 March 2011 Public What this document is about

This is a draft decision document, which accompanies a draft permit.

Consultation It explains how we have considered the Applicant’s Application, and why we have included the specific conditions in the draft permit we are proposing to issue to the Applicant. It is our record of our decision-making process, to show how we have taken into account all relevant factors in reaching our position. Unless the document explains otherwise, we have accepted the Applicant’s proposals.

The document is in draft at this stage, because we have yet to make a final decision. Before we make this decision we want to explain our thinking to the public and other interested parties, to give them a chance to understand that thinking and, if they wish, to make relevant representations to us. We will make our final decision only after carefully taking into account any relevant matter raised in the responses we receive. Our mind remains open at this stage: although we believe we have covered all the relevant issues and reached a reasonable conclusion, our ultimate decision could yet be affected by any information that is relevant to the issues we have to consider. However, unless we receive information that leads us to alter the conditions in the draft Permit, or to reject the Application altogether, we will issue the Permit in its current form.

In this document we frequently say “we have decided”. That gives the impression that our mind is already made up; but as we have explained above, we have not yet done so. The language we use enables this

Newhurst ERF Page 1 of 150 EPR/TP3036KP

document to become the final decision document in due course with no more re-drafting than is absolutely necessary.

We try to explain our decision as accurately, comprehensively and plainly as possible. Achieving all three objectives is not always easy, and we would welcome any feedback as to how we might improve our decision documents in future. A lot of technical terms and acronyms are inevitable in a document of this nature: we provide a glossary of acronyms near the front of the document, for ease of reference.

Preliminary information and use of terms

We gave the Application the reference number EA/EPR/TP3036KP/A001. We refer to the Application as “the Application” in this document in order to be consistent.

The number we propose to give to the permit is EPR/TP3036KP. We refer to the proposed permit Draftas “the Permit” in this Fordocument.

The Application was duly made on 19/2/10.

The Applicant is Biffa WastePublic Services Limited. We refer to Biffa Waste Services Limited as “the Applicant” in this document.

1 Our proposed decision

This Application is to operate an installation subject to the Waste Incineration Directive.

We are minded to grant the Permit to the Applicant. This will allow it to operate the Installation, subject to the conditions in the Permit.

We consider that, in reaching that decision, we have taken into account all relevant considerations and legal requirements and that the permit will ensure that a high level of protection is provided for the environment and human health.

The draft Permit contains many conditions taken from our standard Environmental Permit template including the relevant Annexes. We developed these conditions in consultation with industry, having regard to the legal requirements of the EnviDraftronmental Permitting For Regulations and other relevant legislation. This document does not therefore include an explanation for these standard conditions. Where they are included in the permit, we have considered the Application and accepted the details are sufficient and satisfactory to make the standardPublic condition appropriate. This document does, however, provide an explanation of our use of “tailor-made” or installation- specific conditions, or where our Permit template provides two or more options.

2 How weConsultation reached our decision

The Application was duly made on 19/2/10. This means we considered it was in the correct form and contained sufficient information for us to begin our determination but not that it necessarily contained all the information we would need to complete that determination: see below.

The Applicant made no claim for commercial confidentiality. We have not received any information in relation to the Application that appears to be confidential in relation to any party.

We carried out consultation on the Application in accordance with the EPR, our statutory PPS and our own RGS Note 6 for Determinations involving Sites of High Public Interest. We consider that this process satisfies, and frequently goes beyond the requirements of the Aarhus Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters, which are directly incorporated into the IPPCD, which applies to the Installation and the Application. We have also taken into account our obligations under the Local Democracy, Economic Development and Construction Act 2009 (particularly Section 23). This requires us, where we consider it appropriate, to take such steps as we consider appropriate to secure the involvement of representatives of interested persons in the

Newhurst ERF Page 4 of 150 EPR/TP3036KP

exercise of our functions, by providing them with information, consulting them or involving them in any other way. In this case, our consultation already satisfies the Act’s requirements.

We advertised the Application by a notice placed on our website, which contained all the information required by the IPPCD, including telling people where and when they could see a copy of the Application. We also placed an advertisement in the Loughborough Echo on 26 March 2010.

We placed a paper copy of the Application and all other documents relevant to our determination (see below) on our Public Register at our Trentside Offices, Scarrington Road, West Bridgford, Nottingham, NG2 5FA and also sent a copy to Charnwood Borough Council for its own Public Register. Anyone wishing to see these documents could do so and arrange for copies to be made. The Applicant also placed a copy of the Application at Shepshed Town Council Offices.

We sent copies of the Application to the following bodies, including those with whom we have “WorkingDraft Together Agreements”: For

• Charnwood Borough Council • Leicestershire County and Rutland Primary Care Trust • Food Standards AgencyP ublic • Health and Safety Executive • Severn Trent Water Consultation These are bodies whose expertise, democratic accountability and/or local knowledge make it appropriate for us to seek their views directly.

In addition to our advertising the Application, we undertook a programme of extended public consultation. We attended a public meeting held by the Leicestershire County Council Planning Department on 8 March 2010, and met with Shepshed Town Council on 2 June 2010. We also sent letters to the following stakeholders: • Parish Councils • Charnwood Borough councilors • Local Leicestershire county councilors • North West Leicestershire Labour, Liberal and Conservative parties • Local MP • Local Libraries • Local Colleges and Loughborough University • Loughborough Hospital • Local Leisure Centers

Written comments were also accepted by the Environment Agency well beyond our standard 20 working day consultation period. Further details along with a summary of consultation comments and our response to the representations we received can be found in Annex 4. We have taken all relevant representations into consideration in reaching our draft

Newhurst ERF Page 5 of 150 EPR/TP3036KP

determination.

Although we were able to consider the Application duly made, we did in fact need more information in order to determine it, and issued information notices on 19 October 2010, 12 November 2010, and 1 December 2010. A copy of each information notice was placed on our public register and sent to Charnwood Borough Council for inclusion on its register, as were the responses when received.

In addition to our information notices, we received additional information during the determination from the Applicant. This was a copy of their CADNA noise model files to enable us to audit their noise modelling, which was emailed to us on 23/8/10. The Operator also emailed us on 22/9/10 regarding the provision of noise data.

We also required a Post Conviction Plan to be produced for offences at Elvaston Landfill on 21/4/07, this was provided on 15/12/10.

We made copies of Draftthis extra information availableFor to the public in the same way as the responses to our information notices.

Having carefully considered the Application and all other relevant information, we are now putting our draftPublic decision before the public and other interested parties in the form of a draft Permit, together with this explanatory document. As a result of this stage in the process, the public has been provided with all the information that is relevant to our determination, including the original Application andConsultation additional information obtained subsequently, and we have given the public two separate opportunities (including this one) to comment on the Application and its determination. Once again, we will consider all relevant representations we receive in response to this final consultation and will amend this explanatory document as appropriate to explain how we have done this, when we publish our final decision.

Newhurst ERF Page 6 of 150 EPR/TP3036KP

3 The legal framework

The Permit will be granted, if appropriate, under regulation 13 of the EPR. The Environmental Permitting regime is a legal vehicle which delivers most of the relevant legal requirements for activities falling within its scope. In particular, the Installation is:

• an installation for the purposes of the IPPCD; • a waste incineration installation under the WID; • an operation covered by the WFD, because it processes waste; and • subject to aspects of other relevant legislation which also have to be addressed.

We address some of the major legal requirements directly where relevant in the body of this document. Other requirements are covered in a section towards the end of this document. Draft For We consider that, if we grant the Permit, it will ensure that the operation of the Installation complies with all relevant legal requirements and that a high level of protection will be delivered for the environment and human health. Public We explain how we have addressed specific statutory requirements more fully in the rest of this document.

4 The Installation

4.1 Description of the installation and related issues

4.1.1 The permitted activities

The Installation is subject to the EPR because it carries out an activity listed in Part 1 of Schedule 1 to the EPR:

• Section 5.1 Part A(1)(c) – incineration of non-hazardous waste in an incineration plant with a capacity of 1 tonne or more per hour.

The definition of a WID “incineration plant” includes:

“the site and the entire incineration plant including all incineration lines, waste reception, storage, on-site pre- treatment facilities,Draft waste-fuel and air-supplyFor systems, boiler, facilities for the treatment of exhaust gases, on-site facilities for treatment or storage of residues and waste water, stack, devices and systems for controlling incineration operations, recording and monitoringPublic incineration conditions.”

Many activities which would normally be categorised as “directly associated activities” for EPRConsultation purposes (see below), such as air pollution control plant, and the ash storage bunker, are therefore included in the listed activity description.

An installation also comprises any unlisted “directly associated activities”, which at this Installation includes the generation of electricity using a steam turbine. This is one installation, because the incineration plant and the steam turbine are successive steps in an integrated activity.

Together, these listed and unlisted activities define the legal boundary of the Installation.

4.1.2 The Site

Newhurst Quarry is located in Shepshed, Leicestershire, and forms part of the Charnwood Quarry Complex which is located on the northern edge of Charnwood Forest adjacent to the M1 motorway immediately south of Junction 23. The Charnwood Quarry Complex consists of two linked quarries, both of which are currently inactive: • Newhurst Quarry, located on the west side of the M1 Motorway; and • Longcliffe Quarry, on the eastern side of the Motorway (which is accessed through Newhurst Quarry and under the motorway).

The installation is located at National Grid Reference (NGR) SK 489 181, approximately five kilometres west of the centre of Loughborough. Site access

Newhurst ERF Page 8 of 150 EPR/TP3036KP

is from the A512 Ashby Road East located approximately 66m north of the site, some 300 metres west of Junction 23 on the M1.

There is one SSSI within 2km of the installation, and that is the quarry itself which has a citation for its geology. There are also ancient woodlands, local wildlife sites and local nature reserves within 2km of the installation. There are no SACs or SPAs or Ramsar sites within 10 km of the installation.

The Applicant submitted a plan which we consider is satisfactory, showing the site of the Installation and its extent.

A plan is included in Schedule 7 to the Permit, and the Operator is required to carry on the permitted activities within the site boundary.

Further information on the site is addressed below at 4.2. Draft For Public

Consultation

Newhurst ERF Page 9 of 150 EPR/TP3036KP

4.1.3 What the Installation does

This is an installation for the incineration of waste.

The Applicant has described the facility as an Energy Recovery Facility. However our view is that for the purposes of WID and EPR, the installation is an incinerator because it has no output other than the generation of electricity from the burning of waste that has not undergone significant pre-treatment to enhance its performance as a fuel.

The proposed plant will be totally enclosed within a new building. The main building will be in the region of 47m in height (maximum) and the footprint of the site will be ovoid in shape and orientated along a north-south axis.

The plant will be designed to comply with the requirements of the WID and the management system will be accredited to ISO14001.

The plant is anticipated to generate approximately 29.3MW electrical power when fully operational.Draft Approximately 12% For of the total generated electricity would be used within the facility itself (“parasitic load”). The remainder will be exported to the National Grid.

The Operator has contactedPublic and entered into discu ssions with a number of potential local users of the heat as discussed in section 4.3.7.

A simplified flow diagram depicting the ERF process is shown below: Consultation

Newhurst ERF Page 10 of 150 EPR/TP3036KP

The operation of the plant consists of the following key elements:

• Waste reception; • Combustion; • Energy Recovery; • Flue Gas Treatment; • Emissions Monitoring; • Residue Handling

This process will be contained within two production lines that will operate side-by-side.

• Outside of the main building, the following features would be provided: • site access roads with drainage, lighting, footpaths and vehicle manoeuvring areas; • weighbridges and gatehouse, that allows adequate queuing length off the public highway.D Theseraft facilities wouldFor be staffed when necessary; • electrical equipment to enable connection to the national grid; • storage for the collection, recycling and rainwater runoff attenuation measures; • landscape and securityPublic fencing; and • additional ecological habitats.

The proposed facility will be totally enclosed within the purpose-built new building. The northernConsultation part of the building will contain the bottom ash pre- treatment plant (as described in the “residue handling” section below). From this area, the treated ash will be conveyed to a maturation area; an area bounded by concrete push walls to the north of the building. To the south of the ash pre-treatment area will be the tipping hall and associated bunker (where all of the imported waste will be unloaded), beyond which will be the incinerator grate, boiler, flue gas treatment plant and air cooled condensers. The associated flue stacks, which will be located on the western side of the building, will be approximately 96.5m high.

Waste Reception The source segregated waste (i.e. residual) will be delivered via the site entrance off Ashby Road to a dedicated handling area using bulk transfer vehicles (from transfer stations) and refuse collection vehicles (RCV’s). Vehicles using the site will be covered / enclosed to ensure that waste and odour are not released into the environment. All vehicles delivering waste will be weighed when entering the site and proceed to a vehicle delivery and tipping hall via a one way internal road system, where they will back up and discharge the waste into an underground bunker or storage hopper. From here waste will be transferred to the two parallel process lines and to each combustion chamber via dedicated feed chute and airlock section using grab cranes. The cranes would also be used to mix and break-up the incoming materials to ensure homogeneity of feed to the combustion chambers following inspection.

Newhurst ERF Page 11 of 150 EPR/TP3036KP

A shredder will be provided to process any bulky household waste received and to reduce material to an appropriate size before returning shredded materials for processing.

Air will be extracted from the waste reception hall and used as waste combustion air which helps control odours arising in this area. This reception area will be enclosed with rapid access doors and air louvers to manage traffic and air movements.

Combustion Combustion will take place in two stages, with primary combustion undertaken on a moving mechanical grate to promote the mixing of burning/unburnt wastes. The combustion gas from the primary stage will be heated further in the first pass of the boiler to reach the specified minimum temperature of 850oc for a minimum of two seconds, as required by the WID.

The burnt waste from primary combustion on the moving grate will be removed as an ash (IncineratorDraft Bottom Ash For (IBA)).

Energy Recovery The heat from combustion will be recovered within a waste heat boiler to form high pressure steam, whichPublic is used to drive turbines to generate electricity. A proportion of this site generated energy will be used within the facility itself, but the majority will be exported to the National Grid.

The design ofConsultation the heat recovery boiler is particularly suited to waste combustion and incorporates facilities to minimise dust carry-over and for online cleaning through rapping systems and soot blowers to minimise maintenance impacts. Dust collected from the boilers will be discharged as fly ash and collected with the flue gas treatment residues.

The power generation and auxiliary equipment provided include turbine/generator sets, air condensers and a facility with the potential to extract further value from the partially cooled steam or hot water after it has been through the turbines. This has the potential to provide Combined Heat and Power (CHP) for homes and businesses within a reasonable proximity to the site. If the surplus heat is exploited in this way the overall efficiency of the facility can be increased. The generation of CHP therefore represents a considerable environmental benefit and is further discussed in section 4.3.7.

Flue Gas Treatment An air pollution control system will be in place to treat all flue gases prior to emission from the stack. Limits have been set for these emissions in line with the WID.

The flue gas treatment will be a dry process, managed through a combination of processes: • emission of oxides of Nitrogen (NOx) will be treated by ammonia injection to convert the NOx to nitrogen and water;

Newhurst ERF Page 12 of 150 EPR/TP3036KP

• acid gases will be neutralised by the injection of sodium bicarbonate; • activated carbon injection will be used absorb dioxin emissons; • and filters will be used for dust removal.

Air Pollution Control (APC), residues removed by the flue gas treatment process will be collected in hoppers prior to being exported from the site for further treatment/disposal.

Residue Handling Ash produced during the incineration process will comprise incinerator bottom ash (IBA), boiler ash, fly ash, and air pollution control residues (APC residues) from the flue gas treatment.

On line cleaning of the boiler results in boiler ash, and this ash is transferred from the bottom of the boiler passes to the APC / fly ash silo. Boiler ash is generally considered to be the ash which drops out of the boiler in this fashion, whereas “fly ash” as its name suggests carries through the boiler and onto the bag filters. In summary, the fly-ash, most of the boiler ash, and APC residues will be collectedDraft together and tak Foren either to a hazardous landfill or to an appropriately permitted waste treatment facility, as all three can contain heavy metals.

Incinerator Bottom Ash andPublic a small proportion of the boiler ash are collected and combined within the ERF building and conveyed to the IBA facility.

The IBA facility will allow pre-treatment storage, treatment, long-term storage

and loading intoConsultation lorries, of the IBA produced by the plant. IBA will be processed on a “campaign” basis, using mobile plant as stock accumulates, to produce a secondary aggregate for the construction industry. Processing involves mechanical treatment and maturation to produce stabilised aggregate of several different product grades.

Mechanical treatment will be carried out under cover using mobile plant. Magnetic over-belt and eddy current separators will remove ferrous and non- ferrous metals respectively for recycling. Ash will be sorted into several different size fractions by mechanical screens. A small proportion of ash will be oversize and this will either be crushed on a campaign basis or will be removed from site for disposal to appropriately licensed landfill. Remaining fractions will be transferred to the external stockpile area for maturation.

The key feature of the installation can be summarised in the table below:

4.1.4 Key Issues in the Determination

The key issues arising during this determination were:

• Air quality in the local area • Local health concerns • BAT assessment and we therefore describe how we determined these issues in most detail in this document.

Newhurst ERF Page 14 of 150 EPR/TP3036KP

4.2 The site and its protection

4.2.1 Site setting, layout and history

A Site Condition Report detailing the environmental setting of the site (including geology, hydrogeology and hydrology), pollution history and historical land use of the proposed site has been compiled by the Applicant.

Newhurst Quarry is located in Shepshed, Leicestershire, and forms part of the Charnwood Quarry Complex which is located on the northern edge of Charnwood Forest adjacent to the M1 motorway immediately south of Junction 23.

The Charnwood Quarry Complex consists of two linked quarries, both of which are currently inactive: • Newhurst Quarry, located on the west side of the M1 Motorway; and • Longcliffe Quarry, on the eastern side of the Motorway (which is accessed throughD Newhurstraft Quarry andFor under the motorway).

The published geological map (sheet 141, Loughborough) indicates that the Application site is located upon Middle Triassic sedimentary bedrock predominantly of the MerciaPublic Mudstone Group. The mapping indicates that the majority of the Application site (the central, western and southern parts) is underlain by bedrock comprising the Shepshed Sandstone Member, described as buff or red massive sandstone with subangular Precambrian clasts, and is upConsultation to 30m thick

The site is not located within a Source Protection Zone.

There are three surface watercourses in the vicinity of the Application site; the Black Brook and Wood Brook (being tributaries of the River Soar) located approximately 5km north-east of the Application site, and the Shortcliff Brook, immediately south of the Application site boundary. Additionally, the Blackbrook Reservoir is located approximately 2km to the west of the Application site.

Planning permission to quarry at Newhurst was granted in 1947 and subsequent permissions were granted throughout the 1950's, 1960's and 1970's to extend the quarry complex to the east of the M1 motorway. A number of permissions have also been granted for the disposal of overburden and ancillary plant, buildings and other similar development associated with the quarrying. Historical maps of the site show plant to have been located within the proposed site boundary, including conveyors and buildings.

Section 3.3.1 of the site condition report outlines baseline groundwater quality, from previous groundwater sampling undertaken by RPS in July 2006. The Environment Agency note from the groundwater monitoring results that there are a number of elevated inorganic compounds including barium, magnesium, zinc, potassium, sodium and chloride which is attributed to

Newhurst ERF Page 15 of 150 EPR/TP3036KP

natural mineralisation within the bedrock. Section 3.3.1 also states that there are no elevated levels of organic compounds within the groundwater samples.

It is also apparent from section 3.3.2 of the site condition report that baseline surface water quality from the five locations sampled in January 2006 is compliant with the appropriate Environmental Quality Standards.

No intrusive site investigations have been conducted as part of the environmental permit submission, RPS planning Application 2007 (for the Newhurst Integrated Waste Management Facility) or for the SLR 2009 planning Application for the Energy Recovery Facility. Consequently, baseline reference data for soils and land quality is not available, although there are a number of potential sources of contamination from historical land uses. These potential sources include leaks and spillages of fuels, lubricants and oils.

Fuel oil is listed one of the principal raw materials on the installation. The Operator’s risk assessment for loss of containment or spillage of fuel oil, identifies that thereDraft is the possibility ofFor the contamination of land and proposes that all fuel storage tanks will be bunded, spill kits will be kept on site, and concludes that the residual risk will not be significant.

Public 4.2.2 Proposed site design: potentially polluting substances and prevention measures

Substances whichConsultation will be used and/or produced at the proposed ERF facility include raw materials, fuels, intermediates, products and wastes. Some of these substances have the potential to pollute the soil or groundwater if there were an accident or if measures to protect the land were to fail. However all operational areas of the site will be covered in concrete and rendered impervious to any materials stored. Tanks will be bunded in accordance with industry guidance and maintained to prevent failures.

It is proposed that the ERF building will incorporate a sealed drainage system, and surface water draining from roads and hard standings will be passed through oil interceptors and into a surface water attenuation lagoon, mitigating against hydrocarbon contamination and suspended solids. Wheel wash down water will also be passed through an oil interceptor.

Based on the information in the Application, the Environment Agency is satisfied that the risk of pollution to ground and ground water will be minimised and very low.

4.2.3 Closure and decommissioning

Having considered the information submitted in the Application, we are satisfied that the appropriate measures will be in place for the closure and decommissioning of the Installation, as referred to in section 5.1 of the Best Available Techniques and Operating Techniques (BATOT) section of the

Newhurst ERF Page 16 of 150 EPR/TP3036KP

Application. The Operator states that a site closure plan will be drafted upon completion of the detailed design and finalised and agreed with the Environment Agency prior to commencement of operations, however they give details of the key aspects of the plan which we considered appropriate. Pre-operational condition PO1 requires the Operator to have an Environmental Management System in place before the Installation is operational, which would include a site closure plan.

The Operator has to satisfy us, if it wants to surrender the Permit, that the necessary measures have been taken, both to avoid any pollution risk resulting from the operation of the Installation, and to return the site to a satisfactory state, having regard to the state of the site before the Installation was put into operation. To do this, the Operator has to apply to us for surrender, which we will not grant unless and until we are satisfied that these requirements have been complied with.

4.3 Operation of the Installation – general issues

4.3.1 AdministrativeDraft issues For

The Applicant is the sole Operator of the Installation.

We are satisfied that the ApplicantPublic is the person who will have control over the operation of the Installation after the granting of the Permit; and that the Applicant will be able to operate the Installation so as to comply with the conditions included in the Permit. Consultation The incineration of waste is not a specified waste management activity. The Environment Agency has considered whether any of the other activities taking place at the Installation are SWMAs and is satisfied that none are taking place

We are satisfied that the Applicant’s submitted OPRA profile is accurate.

The OPRA score will be used as the basis for subsistence and other charging, in accordance with our OPRA Scheme. OPRA is the Environment Agency’s method of ensuring Application and subsistence fees are appropriate and proportionate for the level of regulation required.

4.3.2 Management

The Applicant has stated in the Application that they will implement an Environmental Management Systems that will be certified under ISO14001 They have also confirmed, in question 6e of Application form A, that their management system will meet the conditions set out in our guidance. A pre- operational condition (PO1) is included requiring the Operator to provide a summary of the EMS prior to commissioning of the plant and to make available for inspection all EMS documentation. The Environment Agency recognises that certification of the EMS cannot take place until the installation is operational. An improvement condition (IC1) is included requiring the Operator to report progress gaining accreditation of its EMS.

Newhurst ERF Page 17 of 150 EPR/TP3036KP

Our National Enforcement Database has been checked to ensure that all relevant convictions have been declared. The Operator does have relevant, un-spent convictions. Post conviction plans had been submitted, by the Operator, for all convictions, which have been assessed as satisfactory by the Environment Agency. We consider that the Operator satisfies the criteria in our Regulatory Guidance Series, No. RGN 5, on Operator Competence.

Having considered the information submitted in the Application, we are satisfied that appropriate management systems and management structures will be in place for this Installation, and that sufficient financial, technical and personnel resources are available to the Operator to ensure compliance with all the Permit conditions.

4.3.3 Site security

Having considered the information submitted in the Application, we are satisfied that appropriate infrastructure and procedures will be in place to ensure that the site remainsDraft secure. For

4.3.4 Accident management

The Applicant submitted anP Accidentublic Management Plan with the Application, and a revised plan in response to a Schedule 5 request for further information. Having considered the Plan and other information submitted in the Application, we are satisfied that appropriate measures will be in place to

ensure that accidentsConsultation that may cause pollution are prevented but that, if they should occur, their consequences are minimised.

The Applicant also confirmed that the plant design will be subject to a Hazard and Operability, (HAZOP), study to ensure that all possible modes of failure have been considered and addressed.

4.3.5 Off-site conditions

We do not consider that any off-site conditions are necessary.

4.3.6 Operating techniques

We have specified that the Applicant must operate the Installation in accordance with the following descriptions contained in the Application:

Public We have also specified the following limits and controls on the use of raw materials and fuels:

Raw Material orC Fuelonsultation Specifications Justification Gas Oil < 0.1% sulphur content Maximum sulphur content of gas oil used will be < 0.1% w/w in accordance with the Sulphur Content of Liquid Fuels Regulations.

Article 4(4) of the WID requires that the Permit must list explicitly the categories of waste which may be treated. The Application contains a list of those wastes in appendix BATOT6, coded by the European Waste Catalogue (EWC) number, which the Applicant believes may appear in the waste streams entering the plant and which the plant is capable of burning in an environmentally acceptable way. This was amended in the Applicant’s response to a Schedule 5 request for further information dated 19 October 2010. We have specified the permitted waste types, descriptions and where appropriate quantities which can be accepted at the installation in Table S2.2. The responses to the schedule 5 questions have been incorporated into the permit via condition 2.3.1 and table S1.2.

We are satisfied that the Applicant can accept the wastes contained in Table S3.2 of the Permit because: -

Newhurst ERF Page 19 of 150 EPR/TP3036KP

(i) Some of these wastes are categorised as municipal waste in the European Waste Catalogue or are non-hazardous wastes similar in character to municipal waste; (ii) the wastes are all categorised as non-hazardous in the European Waste Catalogue and are capable of being safely burnt at the installation. (iii) these wastes are unlikely to contain harmful components that cannot be safely processed at the installation.

The Installation will take residual waste i.e. that which is not separately collected or otherwise recovered, recycled or composted. Waste codes for separately collected fractions of waste are included in the list of permitted wastes. The response to the 19/10/10 Schedule 5 notice, confirms that this is to cover recyclable materials that are contaminated which cannot be practically recycled. Likewise separately collected organic materials will only be incinerated where anaerobic digestion or composting or similar treatment is not a practical option. Permit condition 2.3.3(c) requires that “waste shall only be accepted if, having been separately collected for recycling, it is contaminated and otherwiseDraft destined for landfill”For

We have limited the capacity of the Installation to 300,000 tonnes per annum. This is based on the installation operating 8000 hours per year at a nominal capacity of 37.4 tonnes perPublic hour.

The installation will be designed, constructed and operated using BAT for the Installation for the incineration of the permitted wastes. We are satisfied that the operating andConsultation abatement techniques are BAT for incinerating these types of waste. Our assessment of BAT is set out in the rest of this document.

4.3.7 Energy efficiency

(i) Consideration of energy efficiency

We have considered the issue of energy efficiency in the following ways:

1. The use of energy within, and generated by the Installation, which is a normal aspect of all EPR permit determinations. This issue is dealt with in this section.

2. The extent to which the Installation meets the requirements of Article 6(6) of the WID, which requires that heat “shall be recovered as far as practicable”. This issue is covered in this section.

3. The combustion efficiency and energy utilisation of different design options for the Installation are relevant considerations in the determination of BAT for the Installation, including the Global Warming Potential of the different options. This aspect is covered in the BAT assessment which we explain in section 6.3 of this Decision Document.

Newhurst ERF Page 20 of 150 EPR/TP3036KP

(ii) Use of energy within, and generated by the Installation

Having considered the information submitted in the Application, we are satisfied that appropriate measures will be in place to ensure that energy is used efficiently within the Installation.

The Application details a number of measures that will be implemented at the Installation in order to increase its energy efficiency:

• the potential exists for waste heat to be used in Community Heating schemes for local housing or business. The Operator is currently considering the opportunities. The steam turbogenerators will be designed to allow the CHP option to be developed in accordance with demand; • space heating requirements in the facility will be provided by waste heat produced by power generation equipment; • furnace sections and all pipework handling process steam and air heaters will be insulated as necessary in order that the external temperature ofD the raftsurface does notFor exceed a temperature safe for personnel and ensure that heat losses are minimised; • all combustion and air handing equipment include seals to ensure controlled ingress of air or to prevent escape of combustion gases etc. A routine maintenanceP ublicprogramme will ensure effectiveness of door/hatch seals etc. • Pre-preparation of waste feed by mixing and removing contraries, will ensure smoothConsultation furnace operation, reducing downtime due to poor fuel characteristics and concomitant combustion problems; • auxiliary burners provided to maintain constant temperature, along with tight controls on combustion conditions; • at the detailed design stage where possible layout of the facility will take advantage of gravity to minimise need to pump/transfer materials around the site

The Sankey diagram, given in section 3.9 of the BATOT section of the Application, estimates that the power requirement of the process is 3500kW for the 300,000 tpa process. It is stated that the plant will run 8000 hours per year. Based on these figures, the specific energy consumption, a measure of total energy consumed per unit of waste processed, will be 93 kWh/tonne. This is in line with data from the BREF for Municipal Waste Incinerators burning waste with a Net CV of 9.2 MJ/kg which shows that the range of specific energy consumptions is as in the table below.

MSWI plant size range Process energy demand (t/yr) (kWh/t waste input)

Up to 150,000 300 – 700 150,000 – 250,000 150 – 500 More than 250,000 60 – 200

Newhurst ERF Page 21 of 150 EPR/TP3036KP

(iii) Compliance with Article 6(6) of the WID

The previous section describes our assessment of energy utilisation. Article 6(6) of the WID requires that heat “shall be recovered as far as practicable”. The Government’s guidance on the WID (WID EPR Guidance, October 2009) lists the following hierarchy of heat recovery options, with (e) as the least preferred option and the optimum being a combination of the other four options: a) use of waste heat from boiler water cooling system b) use of a boiler for steam generation or electricity generation c) use of exhaust steam for process heating or CHP schemes d) internal heat exchange for primary air heating and/or flue gas reheating e) no heat recovery.

Energy recovery fromDraft the hot waste combustion For gases will be achieved via the five stage boiler that includes a series of heat exchangers, super-heaters and economiser. Recovered heat from the combustion gases will be used to produce 120tph superheated steam at 4220C and 62barg. Public Steam will be supplied to a steam turbine turbo-generator set that generates 25.8MW net electrical energy for supply to the national electrical grid. By means of pressure-controlled steam extraction, low-pressure steam at 5barg will be taken forConsultation internal uses within the plant.

After passing through the turbine the expanded steam is condensed in an air- cooled turbine condenser, with the condensate will be returned to the feed water tank.

The current proposal is that the Installation will generate electricity only and has been specified to maximise electrical output with little or not use of waste heat. The Environment Agency’s relevant technical guidance note, SGN EPR 5.01, states that using indicative BAT for municipal waste incineration, where electricity only is generated, will mean that 5-9 MW of electricity should be recoverable per 100,000 tonnes of waste burned. The Sankey diagram in section 3.9 of the Application shows 29.3MW of electricity produced for an annual burn of 300,000 tonnes, which represents 9.8 MW per 100,000 tonnes of waste burned. The Installation is therefore above the indicative BAT range.

The SGN and the WID both require that, as well as maximising the primary use of heat to generate electricity, waste heat should be recovered as far as practicable, i.e. by identifying and utilising opportunities for Combined Heat and Power (CHP) and district heating.

The location of the Installation largely determines whether waste heat can be utilised, and this is a matter for the planning authority. The Applicant carried out a feasibility study (Heat Plan), which showed there was potential to

Newhurst ERF Page 22 of 150 EPR/TP3036KP

provide district heating to local businesses; and opportunities are being explored, in particular GLW Feeds Limited have shown an interest in being supplied with 4,500,000 kwh per annum of steam and 8,500,000 kwh per annum of electricity from the EfW facility. There is provision within the design of the steam turbine to extract low-grade steam for a district heating scheme. Establishing a district heating network to supply local users would involve significant technical, financial and planning challenges.

The WID guidance also states that opportunities to maximise the potential for heat recovery should be considered at the early planning stage, when sites are being identified for incineration facilities. In our role as a statutory consultee on the planning Application, we ensured that the issue of energy utilisation was brought to the planning authority’s attention. We have made comments about this to Leicestershire County Council (the planning authority) in our role as a statutory consultee for the planning Application.

We consider that, within the constraints of the location of the Installation explained above, the Installation will recover heat as far as practicable, and therefore that the requiremDraftents of Article 6(6)For are met, insofar as the Agency’s remit under the EPR is concerned.

(iv) Permit conditions concerning energy efficiency Public Pre-operational condition PO2 requires the Operator to carry out a comprehensive review of the available heat recovery options prior to commissioning, in order to ensure that waste heat from the plant is recovered as far as possible.Consultation

Conditions 1.2.2 and 1.2.3 have also been included in the Permit, which require the Operator to review the options available for heat recovery on an ongoing basis, and to provide and maintain the proposed steam/hot water pass-outs.

The Operator is required to report energy usage and energy generated under condition 4.2 and Schedule 4. The following parameters are required to be reported: total electrical energy generated; electrical energy exported; total energy usage and energy exported as heat (if any). Together with the total MSW burned per year, this will enable the Environment Agency to monitor energy efficiency at the Installation and take action if at any stage the energy efficiency is not considered acceptable.

There are no site-specific considerations that require the imposition of standards beyond indicative BAT, and so the Environment Agency accepts that the Applicant’s proposals represent BAT for this Installation.

4.3.8 Efficient use of raw materials (including water)

Having considered the information submitted in the Application, we are satisfied that the appropriate measures will be in place to ensure the efficient use of raw materials and water.

Newhurst ERF Page 23 of 150 EPR/TP3036KP

The Operator is required to report with respect to raw material usage under condition 4.2. and Schedule 4, including consumption of sodium bicarbonate, activated carbon and ammonia used per tonne of waste burned. This will enable the Environment Agency to assess whether there have been any changes in the efficiency of the air pollution control plant, and the operation of the to abate NOx. These are the most significant raw materials that will be used at the Installation, other than the waste feed itself (addressed elsewhere). The efficiency of the use of auxiliary fuel will be tracked separately as part of the energy reporting requirement under condition 4.2.1.

The Operator states that the use of the alkaline reagent (Sodium Bicarbonate) to neutralise the acid gases, will be optimised to help prevent the production of waste reagent. They will use milled sodium bicarbonate which has an enlarged activated surface area and as a result a high efficiency with reference to the chemical reaction. The Operator states that the abatement system will use a fluidized bed reactor that ensures intensive contact between pollutants and sorbent, providing optimal conditions for neutralisation. Recirculation of bicarDraftbonate increases residence For time and leads to improved utilisation of the reagent and lower stoichiometric values compared with the “no recycle” process.

The Operator has applied toPublic use sodium bicarbonate but states that lime is an alternative which they may consider at the final design stage. Pre-operating condition, PO8, has been set for the Operator to send a report to the Environment Agency confirming which reagent they will be using, and, if it turns out to Consultationbe Lime, to review the impact and BAT assessment to demonstrate that the use of Lime will not have a detrimental effect on the environment and will be considered BAT.

25% aqueous ammonia will be used to reduce the oxides of nitrogen emissions. The ammonia will be will be injected at several injection levels and elevations. Regardless of the operating status of the plant, injection will take place at the level in which optimum reaction temperatures prevail. The automated control system will select the appropriate injection location. The Application states that optimising the flue gas flow in the first pass of the boiler will achieve high removal efficiency for NOx and a low excess of ammonia. This will help to minimise the consumption of ammonia and water.

The facility will also use flue gas recirculation which will provide an effective means of NOx reduction by replacing 10 to 20% of secondary air with re- circulated flue gases that is injected at the secondary air injection level. The use of FGR has the additional benefit of reducing the consumption of reagents used for secondary NOx control.

Powdered activated carbon will be injected to precipitate heavy metals, dioxins and furans by adsorption on its surface. This will be injected separately to the acid gas dosing system, which is considered to be BAT. Using computational fluid dynamics (CFD) the boiler will be designed to reduce rapidly the temperature of the flue gases through the critical

Newhurst ERF Page 24 of 150 EPR/TP3036KP

temperature range, to minimise risk of dioxin reformation, which will minimise required usage of activate carbon. The Application states that appropriate measures will be taken to ensure that raw materials are used efficiently.

Auxiliary low sulphur gas oil burners are fitted for start-up and to maintain temperatures within the secondary combustion zone above 850OC for two seconds. An alternative fuel would be natural gas but the Application states that there is no mains natural gas available. The auxiliary burner is designed specifically for use in waste incinerators. The control system will ensure the burner system operates as specified and provides the correct fuel/air ratio. The Application states that appropriate measures will be taken to ensure that raw materials are used efficiently.

Water,

SGN EPR 5.01 states that “Incinerators are not generally considered to be major users of water. Water use is not therefore a primary environmental concern although it is important to recognise that wet scrubbing and some cooling systems canDraft consume more water.For The minimisation of water consumption will however make a contribution to improving environmental performance of the installation, but should be considered on a case by case basis. “ Public Major water uses in incineration plants are:

• gas scrubbing, particularly wet scrubbing – However, the Operator has applied toC useonsultation dry scrubbing • ash discharge quench baths - The Operator intends to use process water for quenching bottom ash and to harvest rainwater to top up the ash quench water • evaporation from wet cooling towers - The Operator intends to use air cooled condensers

Other uses include boiler water make up and wash down operations.

Process water will be used efficiently in the facility, by in particular using the following techniques:

• Quantity of water usage to be monitored; • Preferential use of dry scrubbing systems; • Recirculation of water where possible, e.g. process water will be used for quenching bottom ash • Use of trigger controls on all hoses and washing equipment; • Direct measurement of fresh water consumption; • Separate contaminated and non-contaminated streams of water; and • Use of uncontaminated site drainage and run-off water in the process.

Newhurst ERF Page 25 of 150 EPR/TP3036KP

4.3.9 Avoidance, recovery or disposal with minimal environmental impact of wastes produced by the activities

This IPPCD requirement addresses wastes produced at the Installation and does not apply to the waste being treated there. The principal waste streams the Installation will produce are bottom ash, air pollution control residues and recovered ferrous metals and non ferrous metals.

The first objective is to avoid producing waste at all. Waste production will be avoided by achieving a high degree of burnout of the ash in the furnace, which results in a material that is both reduced in volume and in chemical reactivity. Condition 3.1.2 and associated Table S3.4 specify limits for loss on ignition, LOI, in bottom ash of 5%. Compliance with this limit will demonstrate that good combustion control and waste burnout is being achieved in the furnaces and waste generation is being avoided where practicable.

Most incinerator bottom ash (IBA) is likely to be classified as non-hazardous waste. However, IBADraft is classified on the EuropeanFor List of Wastes as a “mirror entry”, which means IBA is a hazardous waste if it possesses a hazardous property.

Air pollution control (APC)Public residues from flue gas treatment are hazardous waste and therefore must be sent for disposal to a landfill site permitted to accept hazardous waste, or to an appropriately permitted facility for treatment.

In order to ensureConsultation that the IBA and APC residues are adequately characterised and sent to appropriate disposal or recovery facilities, pre- operational condition PO3 requires the Operator to provide a written plan for approval detailing the ash sampling protocols. Table S3.4 requires the Operator to carry out an ongoing programme of monitoring.

The Application states that magnetic over-belt and eddy current separators will remove ferrous and non-ferrous metals from the IBA respectively. These metals will be sent for recycling.

The Application also proposes that ash will be sorted into several different size fractions by mechanical screens. A small proportion of ash will be oversize and will be removed from site for disposal to a non-hazardous landfill. Remaining fractions will be transferred to the external stockpile area for maturation. Maturation will involve exposure to air and water, achieved by stockpiling the material under cover. Carbon dioxide in air will reduce both ash pH through carbonation reactions and metal solubility. Water will be used to remove soluble metal salts, chlorides, and sulphates.

The maturation process will last for several weeks and will take place in the external walled storage area. Maturation will be required to stabilise ash to ensure leaching properties are acceptable for use as an aggregate. Run off from the ash piles will be contained within the walled storage area and directed to a drainage system. This water will drain into a wash water storage tank that provides settlement/storage, before re-use on the ash piles. The

Newhurst ERF Page 26 of 150 EPR/TP3036KP

water will be sprayed onto the ash to maintain correct conditions for maturation and prevent fugitive dust emission. Once processed, aggregate will be stockpiled in covered maturation areas awaiting sale.

The Applicant’s stated aim is to recycle the IBA as aggregate. The Applicant is currently in discussions with Bottom Ash recyclers and construction companies.

Having considered the information submitted in the Application, we are satisfied that waste production will be avoided as far as possible, and where waste is produced it will be recovered unless technically and economically impossible.

We are satisfied that waste from the Installation that cannot be recovered will be disposed of using a method that avoids or reduces any impact on the environment. Standard condition 1.4.1 will ensure that this position is maintained. Draft For Public

5. Minimising the Installation’s environmental impact

This section of the document explains how we have approached the critical issue of assessing the likely impact of the Installation on human health and the environment, and what measures we are requiring to ensure a high level of protection. For an installation of this kind, the principal emissions are those to air, although we also consider those to land and water.

5.1 Assessment Methodology

We have reviewed the Applicant’s assessment of the likely environmental impact of emissions from the Installation. This is an important step in determining what conditions are appropriate for the Permit, and in particular the basis for setting emission limit values (ELVs).

The impact assessment has adopted the criteria set out in the Agency’s Horizontal GuidanceDraft Note H1. The H1 Formethodology uses a concept of “process contribution (PC)”, which is the estimated concentration of emitted substances after dispersion into the receiving environmental media at the point where the magnitude of the concentration is greatest. The guidance provides a simple method Publicof calculating PC primarily for screening purposes and for estimating process contributions where environmental consequences are relatively low. It is based on using dispersion factors. These factors assume worst case dispersion conditions with no allowance made for thermal or momentum Consultationplume rise and so the process contributions calculated are likely to be an overestimate of the actual maximum concentrations. More accurate calculation of process contributions can be achieved by mathematical dispersion models, which take into account relevant parameters of the release and surrounding conditions, including local meteorology – these techniques are expensive but normally lead to a lower prediction of PC. The Applicant has the choice to use either method.

The first step in this process is to screen out those emissions which are environmentally insignificant. H1 sets the following criteria:

• the contribution to long-term ground level concentrations is less than 1% of the relevant air quality standard; and • the contribution to short-term ground level concentrations is less than 10% of the relevant air quality standard.

The long term 1% process contribution insignificance threshold is based on the judgements that: • It is unlikely that an emission at this level will make a significant contribution to air quality; • The 1% threshold is one hundredth of the standard and provides a substantial safety margin to protect health and the environment.

Newhurst ERF Page 28 of 150 EPR/TP3036KP

The short term 10% process contribution insignificance threshold is based on the judgements that: • spatial and temporal conditions mean that short term process contributions are transient and limited in comparison with long term process contributions; • the proposed 10% threshold is one tenth of the of the standard and provides a substantial safety margin to protect health and the environment.

The H1 methodology is based on the conservative approach, which adopts a “worst-case scenario” approach, as explained below. If, on this conservative basis, the emission’s impact is assessed as “insignificant”, then the Environment Agency considers that the proposed technique for minimising pollution is BAT, as it would not be reasonable or proportionate to require an Operator to take further or additional steps, or incur additional expenditure, where no material environmental benefit results.

It is important to understandDraft that an exceedence For of these H1 thresholds does not mean an emission will have a significant impact, but only that it cannot be screened out as insignificant.

Where an emission cannotPu be screenedblic out at this stage, a more detailed assessment should be carried out to determine the actual environmental impact, for example, by taking into account existing background (ambient) concentrations of the emission in question and using dispersion modelling. The Applicant hasConsultation in this case provided a detailed air dispersion model.

This more detailed assessment could result in some of the further emissions being screened out as insignificant against the above criteria. Where an emission is not screened out as insignificant, the Applicant is required to consider all the potentially available techniques for minimising the emission, and to explain why its specific proposal is in fact BAT for the Installation. We will not necessarily agree, and we may at the very least require further information before we are prepared to accept the Applicant’s justification: the consultation on the Application may also yield information that shapes our determination in this respect.

For those pollutants where the PEClong term exceeds 70% of an EQS or the PCshort term exceeds 20% of the headroom between an EQS and the background concentration, we determine whether exceedences of EQS are likely. This is done through detailed audit and review of the Applicant’s impact assessment taking headroom and modelling uncertainties into account. Where exceedences are identified, we may require the Applicant to go beyond what would normally be considered BAT for the Installation in order to reduce releases from the Installation to ensure that there is no significant pollution or risk to human health. Whether or not exceedences are considered likely, the Application is subject to the requirement to operate in accordance with BAT.

Newhurst ERF Page 29 of 150 EPR/TP3036KP

Once the BAT for the Installation are established, we set ELVs based on use of those BAT. However, that is not the end of the exercise, because we also take into account local factors (for example, particularly sensitive receptors nearby such as a SSSI) and relevant Environmental Quality Standards (see further below). Again, even if we agree with the Applicant as to what is BAT, these additional factors may lead us to include more stringent conditions than those proposed by the Applicant. If we consider that emissions would cause significant pollution, we would refuse the Application.

WID on the other hand is based on setting mandatory emission limit values. Although the WID limits are designed to be stringent, and to provide a high level of environmental protection, they do not necessarily reflect what can be achieved by new plant. As the WID itself states, its limits are “a necessary but not sufficient condition” for compliance with the requirements of the IPPCD, which also applies to this Installation. The IPPCD requires that emissions should be prevented or minimised, so it may be possible and desirable to achieve emissions below WID limits.

Even if the WID limitsDraft are appropriate, operationalFor controls complement the emission limits and should generally result in emissions below the maximum allowed; whilst the limits themselves provide headroom to allow for unavoidable process fluctuations. Actual emissions are therefore almost certain to be below emissionPublic limits in practice, because any Operator who sought to operate its installation continually at the maximum permitted level would almost inevitably breach those limits regularly, simply by virtue of normal fluctuations in plant performance, resulting in enforcement action (including potentiallyConsultation prosecution) being taken. The assessment is therefore a “worst-case” scenario.

Should the Installation, once in operation, emit at rates significantly below the limits included in the Permit, we will consider tightening ELVs appropriately. We are, however, satisfied that emissions at the permitted limits would ensure a high level of protection for human health and the environment in any event.

5.2 Air Quality Assessment

The Applicant assessed the Installation’s potential emissions to air against the relevant air quality standards, and potential impact upon local habitat sites and human health. These assessments predicted the potential effects on local air quality from the Installation’s stack emissions using the BREEZE AERMOD dispersion model, which is accepted as one of the best practice computer models. The model used 5 years of meteorological data, between 2004 and 2008, collected from East Midlands Airport. The impact of the terrain surrounding the site upon plume dispersion was considered in the dispersion modelling using terrain data, which was applied to the entire modelling area. The concentrations reported in the assessments were the maximum ground level concentrations predicted by the dispersion modelling package, using the average of the 5 year meteorological data set.

Newhurst ERF Page 30 of 150 EPR/TP3036KP

The air impact assessments, and the dispersion modelling upon which they were based, employ assumptions. • First, they assumed that the ELVs in the Permit would be those in the WID. • Second, and conservatively, they assumed that the Installation operates continuously at the daily average WID emission limit values or the WID spot sample emission limits to predict the long term air impacts of the installation.

However, the Operator also used daily average WID emission limit values for the short term air impacts of the installation. A more conservative model would be to use the half hourly average WID emission limits for those pollutants monitored continuously. We have assessed this scenario ourselves using our own check modelling (a copy of our internal report, C594a, from our Air Quality Modelling and Assessment Unit has been placed on the public registers).

The Operator has divided the WID emission limit for Group 1 metals by 2, and the Group 3 metals WIDDraft emission limit by For9 to calculate the predicted metals emissions from the 2 stacks. This still uses emissions which are higher than actually experienced in currently operating incinerators. However, a more conservative assessment would be to assume that each individual metal is emitted at the total WID limit.Public We have considered this absolute worst in our own check modelling of the emissions.

We have carried out our own modelling to check the applicant’s predictions. We used meteorologicalConsultation data observed at Watnall (Nottingham) weather centre between 2003 and 2007 and our own terrain data. We also used our own corrected emission rates based on WID limits.

The way in which the Applicant used dispersion models, its selection of input data, and the assumptions it made have been reviewed by the Environment Agency, so that we have satisfied ourselves that the modelling presents a reasonably reliable picture. We agree with the Applicant’s conclusion, that the predicted concentrations of all pollutants considered are well within the relevant air quality objectives and environmental assessment levels.

We also audited the air quality and human health impact assessment and agree that the conclusions drawn in the report are acceptable.

The results of the Applicant’s model are summarised in the tables below:

Newhurst ERF Page 31 of 150 EPR/TP3036KP

5.2.1 Long-term impact of emissions to air

The Operator’s predicted long term impact of emission to air is as follows:

Note 1 All the above concentration figures are in µg/m3 Note 2 Applicant had quoted double background figure so this has been corrected in table above Note 3 Applicant provided no background data, but gave different PEC figure. This has been corrected in table above. As all, but Cr(VI), PC results are insignificant the background data was not required to assess these impacts. Cr(VI) will be discussed in section 5.2.4.

As discussed earlier, the Operator has divided the WID emission limit for both Group 1 metals by 2, and the 9 Group 3 metals WID emission limit by 9 to calculate the predicted metals emissions from the 2 stacks. This still gives emission concentrations that are higher than typical emissions from waste incinerators. A more conservative assessment would be to assume that each individual metal is emitted at the total WID limit. We checked this as part of our modelling of the emissions and concluded that, even at 100% of the WID limit, no Group 1 or Group 3 metal, other than Chromium (VI), will exceed their respective EALs. Chromium (VI) will be discussed in section 5.2.4.

5.2.2 Short-term impact of emissions to air

The Operator’s predicted short term impact of emission to air is as follows:

Note 1 All the above concentration figures are in µg/m3 Note 2 For the assessment of short term impacts the PEC is determined by adding twice the long term background concentration to the short tem process contribution.

However, the Operator also used daily average WID emission limit values for the short term air impacts of the installation. A more conservative model would be to use the half hourly average WID emission limits for those pollutants monitored continuously (except for the daily SO2 EQS). This was done by the Environment Agency as part of our check modelling, and we found that even using the higher short term WID emission limits there would be no exceedences of any EAL or EQS.

As discussed earlier, the Operator has also divided the WID emission limit for both Group 1 metals by 2, and the 9 Group 3 metals WID emission limit by 9 to calculate the predicted metals emissions from the 2 stacks.

Newhurst ERF Page 33 of 150 EPR/TP3036KP

A more conservative assessment would be to assume that each individual metal is emitted at the relevant WID limit. We checked this as part of our check modelling of the emissions and concluded that, even at 100% of the WID limit, no Group 1 or Group 3 metal will exceed their respective EALs

From the tables above, and our own check modelling, the following emissions can be screened out as insignificant in that the process contribution is < 1% of the long term EQS/EAL and <10% of the short term EAQ/EAL: • PM10 • PM2.5 • CO • HCl • HF • TOC • Thallium • Mercury • Antimony • Chromium(III) Draft For • Cobalt • Copper • Lead • Manganese Public • Vanadium • Ammonia Therefore we consider the Applicant’s proposals for preventing and minimising the Consultationemissions of these substances to be BAT for the Installation.

From the tables above, the long term emissions of Cadmium and Arsenic are not screened out as insignificant. From our check modelling, assuming each metal is emitted at 100% of the relevant WID limit, the long term emissions of Nickel is also not screened out as insignificant.

Also, from our check modelling of short term emissions, using the half hourly WID emission limits for those pollutants monitored continuously, and assuming each metal is emitted at 100% of the relevant WID limit, NO2, SO2 and Vanadium maximum concentrations are predicted to exceed 10% of the relevant EQS.

However these emissions can not be considered to have the potential to give rise to significant pollution in that the predicted environmental concentrations are less than 70% of the short term and long term EQS/EALs (apart from NO2 discussed below). For these emissions, we have carefully scrutinised the Applicant’s proposals to ensure that they are applying the Best Available Techniques to prevent and minimise emissions of these substances. This is reported in section 6 of this document.

Also from the tables above the long term emissions of NO2 are considered to have the potential to give rise to significant pollution in that the predicted environmental concentration exceeds 70% of the long term EQS/EAL.

Newhurst ERF Page 34 of 150 EPR/TP3036KP

The PC for NO2 for long term emissions is predicted to be 1.1% which is only just over the 1% threshold of insignificance, and is actually just 1.4% of the current background levels of NO2 in the area. There is also considerable headroom between the PEC and the EQS. It is important to remember that this prediction is based on a worst case scenario of the plant emitting at the NO2 WID limit continuously all the year round. This would not happen in reality. Consequently we consider that emissions of NO2 will not pose a risk of significant pollution.

For the NO2 emissions we have carefully scrutinised the Applicant’s proposals to ensure that they are applying the Best Available Techniques to prevent and minimise emissions of these substances. This is reported in section 6 of this document

The Operator did not provide background data for Chromium(VI) and this will be discussed in section 5.2.4.

Draft For 5.2.3 Assessment of emissions of PM10 and PM2.5

The impact on air quality from particulate emissions has been assessed against EQS for PM10 (particlesPublic of 10 microns and smaller) and PM2.5 (particles of 2.5 microns and smaller). For PM10, the EU EQS are a long term annual average of 40 μg/m3 and a short term daily average of 50 μg/m3 . For 3 PM2.5 the EU EQS of 25 μg/m as a long-term annual average is to be achieved by 2010Consultation (as a Target Value and by 2015 as a Limit Value).

The impact of the installation against these standards and guidelines is shown in the table below – all concentrations are shown as μg/m3. The assessment assumes that all particulate emissions are PM10 or PM2.5 and that both PM10 and PM2.5 will be emitted at the WID emission limit values

Pollutant EQS Back- Process PC as Predicted PEC / EAL ground Contribution % of Environmental as % Conc (PC) EQS / Concentration EQS / EAL (PEC) EAL PM10 40 24.1 0.03 0.08 24.11 60.3 50 48.1 0.11 0.22 48.21 96.4 PM2.5 25 14.1 0.03 0.12 14.13 56.5

The above assessment is considered to represent a worst case assessment in that: - • It assumes that the plant emits particulates continuously at the WID limit. Whereas actual emissions from similar plant are normally in the range 1 to 5 mg/m3. • It assumes all particulates emitted are below either 10 microns (PM10) or 2.5 microns (PM2.5), when some are expected to be larger.

Newhurst ERF Page 35 of 150 EPR/TP3036KP

The above assessment shows that the predicted process contribution for emissions of PM10 is below 1% of the long term air quality standard and below 10% of the short term air quality standard and so can be considered insignificant.

The above assessment shows that the predicted process contribution for emissions of PM2.5 is also below 1% of the long-term annual average air quality objective. Therefore the Environment Agency concludes that particulate emissions from the installation will not give rise to significant pollution.

There is currently no measurement standard specifically for fine particulate matter in the PM2.5 fraction. Whilst the Environment Agency is confident that current monitoring techniques will capture the fine particle fraction (PM2.5) for inclusion in a measurement of total particulate matter, a permit condition has been included that will require a full analysis of particle size distribution in the flue gas, and hence determine the ratio of fine to coarse particles. In the light of current knowledge and available data however the Environment Agency is satisfied that the healthDraft of the public wouldFor not be put at risk by such emissions. Improvement condition IC2 has been imposed requiring the Operator to carry out tests to determine the particle size distribution in the exhaust gas emissions. Public 5.2.4 Arsenic, Nickel and Chromium (VI)

The 2009 report of the Expert Panel on Air Quality Standards (EPAQS) – “Guidelines forConsultation Metal and Metalloids in Ambient Air for the Protection of Human Health”, proposes new ambient air quality guidelines for Arsenic, Nickel and Chromium (VI). These guidelines have been incorporated as EALs in the revised H1 Guidance issued by the Agency in 2010.

Arsenic, Nickel and Chromium are three of the nine Group 3 metals whose emissions are subject to a mandatory minimum emission limit by the WID. WID sets an aggregate limit of 0.5 mg/m3 for all nine Group 3 metals.

The EPAQS guidelines refer only to that portion of the metal emissions 3 contained within PM10 in ambient air. The new guidelines are 3 ng/m for Arsenic, 20 ng/m3 for Nickel and 0.2 ng/m3 for Chromium (VI). These are significantly lower than previous EALs.

The Applicant used these revised EALs for their prediction of impacts for long term air emissions. They predicted that the EALs for Arsenic and Nickel would not be exceeded, and our own modelling has confirmed this. They predicted that the process contribution of Chromium (VI) would not be insignificant, but did not provide any background data to enable a PEC to be predicted. Thus the Applicant’s assessment does not fully predict whether the revised EAL for Chromium (VI) will be exceeded.

The WID limit for Group 3 metals of 0.5 mg/m3 covers gaseous and vapour forms of the metals and their compounds as well as that present in particulate matter. WID has a separate emission limit values for emissions to air of total

Newhurst ERF Page 36 of 150 EPR/TP3036KP

particulate material. The EPAQS guideline also refers to Chromium (VI) only whereas the Group 3 WID limit includes all Chromium.

Measurement of Chromium (VI) at the levels anticipated at the stack emission points is expected to be difficult, with the likely levels being below the level of detection by the most advanced methods. We have considered the concentration of total chromium and chromium (VI) in the APC residues collected upstream of the emission point for existing Municipal Waste incinerators and have assumed these to be similar to the particulate matter released from the emission point. This data shows: 1. The mean proportion of Cr(VI) to total Cr is less than 1%. There are two outliers at 2%. 2. The mean total Cr emission from these plants is 0.006 mg/m3 (max 0.03 mg/m3). 3. The mean Cr(VI) emission concentration (based on the bag dust ratio) is 2.1 * 10-5 mg/m3 (max 1.0 * 10-4). This data is remarkablyDr self-consistent.aft For

Based on these data, we consider it remains a conservative assumption to consider that the maximum Cr(VI) emission concentration will be 1.3E- 04mg/m3. We have used thisPublic data to model the predicted Cr(VI) impact.

The EPAQS 2009 report sets out information on background levels of chromium. This installation is located in a semi rural area located next to the M1 motorway. ConsultationAs the main emitters of Chromium are power stations, smelters and the Chromium industry rather than traffic, the location will be considered rural. The background levels, for rural locations, proposed in the EPAQS report are as follows: -

Chromium (VI) 0.04 to 0.14 ng/m3 (20% of Chromium level)

Using the highest background figure, 0.14ng/m3, the PEC for Chromium (VI) ,using the Applicant’s data, can be calculated and is shown in the table below:

Pollutant EQS / Back- Process PC as % Predicted PEC as EAL ground Contribution of EQS / Environmental % EQS ng/m3 Conc. (PC) EAL Concentration / EAL ng/m3 ng/m3 (PEC) ng/m3 Chromium(VI) 0.2 0.14 0.017 8.5 0.157 78.5

Newhurst ERF Page 37 of 150 EPR/TP3036KP

The table below shows our assessment using the data referred to above.

Pollutant EQS / Back- Process PC as % Predicted PEC as EAL ground Contribution of EQS / Environmental % EQS ng/m3 Conc. (PC) EAL Concentration / EAL ng/m3 ng/m3 (PEC) ng/m3 Chromium(VI) 0.2 0.14 3.6E-04 0.18 0.14 70.2%

This assessment shows that a breach of the air quality guidelines for Chromium (VI) is unlikely. Whilst the PEC as a percentage of the EQS is just over 70%, the PC is considerably less than 1% of the EQS. Given the size of the PC and the available headroom emissions of Chromium (VI) can be considered insignificant.

The installation has been assessed as meeting BAT for control of emissions to air. See section 5.6 of this document.

Therefore taking all theseDraft factors into ac count,For it is considered appropriate to set an improvement condition requiring confirmation of the assessment made above based on actual measurements of emissions. This is included as IC3. A period of one year’s data has been specified to take account of any natural variation in the waste composition.Public The Improvement Condition seeks to verify whether the actual releases are as expected within these limits, in which case no further action is required.

In the event thatConsultation the assessment were to indicate a risk of the air quality guidelines being exceeded, the Environment Agency could specify a specific emission limit value for Chromium as appropriate or seek beyond BAT improvements to the abatement technology employed.

Thus, further assessment of actual Chromium emissions from the installation is expected to demonstrate that the proposed EPAQS air quality guidelines can be achieved for Chromium (VI).

5.3 Human health risk assessment

In carrying out air dispersion modelling and comparing the predicted environmental concentrations with air quality standards and environmental action levels; the Applicant has effectively made a health risk assessment for many pollutants. Air quality standards and environmental actions levels have been developed primarily in order to protect human health; and for many pollutants exposure by inhalation is the principal exposure route.

The Applicant’s and our check monitoring assessment of the impact from • PM10 • PM2.5 • CO • HCl • HF • TOC • Thallium Draft For • Mercury • Antimony • Chromium(III) • Cobalt Public • Copper • Lead • Manganese • AmmoniaC onsultation have all indicated that the installation emissions are insignificant; where the impact of emissions of: • Cadmium • Arsenic • Vanadium • NO2 • SO2 • Chromium(VI) have not been found to be insignificant, the assessment still shows that the predicted environmental concentrations are within air quality standards or environmental action levels.

However for dioxins, furans and some metals, the principal exposure route is through ingestion, usually through the food chain, and the risk to health is through accumulation in the body over a period of time. A different form of risk assessment is therefore required for these materials.

5.3.1 Assessment of Health Effects from Dioxins, Furans and Metals

Two models are available to predict the dioxin intake for comparison with the Tolerable Daily Intake (TDI) recommended by the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment, known as

Newhurst ERF Page 39 of 150 EPR/TP3036KP

COT. These are the Human Health Risk Assessment Protocol (HHRAP) and the HMIP model.

HHRAP has been developed by the US EPA to calculate the human body uptake of a range of carcinogenic pollutants and to determine the mathematic quantitative risk in probabilistic terms. In the UK, in common with other European Countries, we consider a threshold dose below which the likelihood of an adverse effect is regarded as being very low or effectively zero. The HMIP model uses a similar approach to the HHRAP model, but does not attempt to predict probabilistic risk. Either model can however be used to make comparisons with the TDI.

The TDI is the amount of a substance that can be ingested daily over a lifetime without appreciable health risk. It is expressed in relation to bodyweight in order to allow for different body size, such as for children of different ages. In the UK, the COT has set a TDI for dioxins and furans of 2 picograms I-TEQ/Kg-body weight/day (N.B. a picogram is a million millionths (10-12) of a gram). Draft For In addition to an assessment of risk from dioxins and furans, the HHRAP model enables a risk assessment from human intake of a range of heavy metals. Public The Applicant has assessed the potential health impacts of the predicted emissions of metals from the proposed facility, along with emissions of dioxins and furans. This was undertaken in two parts: Consultation (i) a methodology based on contaminated land exposure analysis (CLEA) for metal deposition to land (ii) the HMIP detailed quantitative risk assessment for dioxin and furan cumulative exposure.

Ground level concentrations of the assessed substances were calculated using air dispersion models. This is set out in table 5-2 of Appendix BATOT13 “Human Health Risk Assessment” for dioxins, and table 6-4 of Appendix BATOT7 “Atmospheric Dispersion Modelling” of the Application.

The CLEA model, for metal deposition, does not include all exposure pathways relevant for a human health risk assessment such as ingestion of surface water and secondary uptake through ingestion (consumption of locally-grown produce, locally-raised animal tissue, local milk products, locally-caught fish and maternal breast milk by local babies) and usually results in a prediction which is a small fraction of the total exposure. Hence the cumulative metal exposure estimates derived by the Applicant are considered to be incorrect.

The HMIP procedure for estimating dioxin and furan exposure does take account of all significant uptake routes and is considered to be appropriate.

Newhurst ERF Page 40 of 150 EPR/TP3036KP

We carried out check modelling which included all pathways and metals as well as dioxins and furans, to assess the impact of dioxins and furans and metals on human health using the HMIP methodology and HHRAP. We agree with the Applicant’s conclusions that it is unlikely that dioxins intake will exceed the Tolerable Daily Intake. The predicted daily intake of metals is likely to be low compared with the USEPA reference doses.

Overall, taking into account the conservative nature of the impact assessment models used by the Applicant and ourselves (i.e. that it is based upon an individual exposed for a life-time to the effects of the highest predicted airborne concentrations and consuming mostly locally grown food), it was concluded that the operation of the proposed facility will not pose a significant carcinogenic or non-carcinogenic risk to human health.

5.3.2 Prediction of Tolerable Daily Intake for dioxins and furans

As part of the health risk assessment the daily intake of dioxins and furans by local receptors resultingDraft from the operation For of the proposed facility was assessed against the Tolerable Daily Intake (TDI) values for dioxins and furans established by the World Health Organisation (WHO) and the UK Committee on Toxicity (COT). The TDI is the amount of a substance that can be ingested daily over aPublic lifetime without appreciable health risk. It is expressed in relation to bodyweight in order allow for different body size, such as for children of different ages. In the UK, the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (known as the COT) has set aConsultation TDI of 2 picograms I-TEQ (equivalent to the most toxic dioxin) per kg bodyweight per day. The World Health Organisation has set a range for its TDI of 1-4 pg I-TEQ/kg bw/day (a picogram is a million millionth (10-12) of a gram).

The results of the assessment of dioxin intake, resulting from emissions from the proposed facility, are detailed in the table below. (worst –case results for each category are shown). The results showed that the predicted daily intake of dioxins at all receptors, resulting from emissions from the proposed facility, were significantly below the recommended TDI levels.

Receptor Max predicted intake COT TDI Infant 0.131 2 Child 0.01 2 Adult 0.005 2 Farmer 0.015 2 Farm Child 0.028 2 Calculated maximum daily intake of dioxins by local receptors resulting from the operation of the proposed facility (pg TEQ/ kg-BW/day)

The FSA has reported that recent dietary studies have shown that estimated total dietary intakes of dioxins and dioxin-like PCBs by all age groups fell by around 50% between 1997 and 2001, and are expected to continue to fall. In 2001 the average daily intake by adults in the UK from diet was 0.9 pg WHO-

Newhurst ERF Page 41 of 150 EPR/TP3036KP

TEQ/kg bodyweight. The TDI predicted by the modelling is substantially below this figure.

We carried out check modelling to assess the impact of dioxins and furans on human health using the HMIP methodology and the Human Health Risk Assessment Protocol (HHRAP). We agree with the Applicant’s conclusions that it is unlikely that dioxins intake will exceed the Tolerable Daily Intake

5.3.3 Environment Agency Review of Health Risk Assessment

The Environment Agency has reviewed the methodology employed by the Applicant to carry out the health impact assessment from persistent substances.

We have concluded that the impact from proposed emissions is unlikely to exceed air quality or human health assessment criteria.

The Health ProtectionDraft Agency and Leicestershire For County and Rutland Primary Care Trust were consulted with the EP Application submitted for the proposed facility and concluded that they had no significant concerns regarding the risk to the health of the local population from the installation. Public Concerns about the prevalence of Asthma and respiratory diseases were raised by a local GP surgery and members of the public, and we did ask the HPA to comment on this. They did not hold data on health statistics for the area but statedConsultation that in their view the site should not lead to a significant worsening of air quality. They further re-iterated that while it is not possible to rule out adverse health effects from modern, well regulated municipal waste incinerators with complete certainty, any potential damage to the health of those living close-by is likely to be very small, if detectable.

The Food Standards Agency were also consulted during the permit determination process and they concluded that it is unlikely that there will be any unacceptable effects on the human food chain as a result of the operations at the installation. Details of the responses provided by the PCT, HPA and FSA to the consultation on this Application can be found in Annex 2.

5.3.4 Other Health Considerations

In September 2009 the HPA produced a position statement entitled “The Impact on Health of Emissions to Air from Municipal Waste Incinerators”. This was then reproduced in February 2010 as an advisory document RPE-13. Their comments can be summarised as follows:

“The Health Protection Agency has reviewed research undertaken to examine the suggested links between emissions from municipal waste incinerators and effects on health. While it is not possible to rule out adverse health effects from modern, well regulated municipal waste incinerators with complete certainty, any potential damage to the health of those living close-by is likely to be very small, if detectable. This view is based on detailed assessments of the effects of air pollutants on health and on the

Newhurst ERF Page 42 of 150 EPR/TP3036KP

fact that modern and well managed municipal waste incinerators make only a very small contribution to local concentrations of air pollutants. The Committee on Carcinogenicity of Chemicals in Food, Consumer Products and the Environment has reviewed recent data and has concluded that there is no need to change its previous advice, namely that any potential risk of cancer due to residency near to municipal waste incinerators is exceedingly low and probably not measurable by the most modern techniques. Since any possible health effects are likely to be very small, if detectable, studies of public health around modern, well managed municipal waste incinerators are not recommended.”

This statement concurs with our previous comments that our assessment of emissions for the proposed plant will not result in a significant risk to human health.

5.3.5 Particulates smaller than 2.5 microns

The Operator will be required to monitor particulate emissions using the method set out in EN 13284-1. This method requires that the filter efficiency must be at least 99.5 % on a test aerosol with a mean particle diameter of 0.3 μm, at the maximumDraft flow rate anticipat ed.For This means that particulate monitoring data effectively captures everything above 0.3 microns and much of what is smaller. It is not expected that even smaller particles will contribute significantly to the mass release rate / concentration of particulates because of their very small mass,Public even if present. This means that emissions monitoring data can be relied upon to measure the true mass emission rate of particulates.

Nano-particles Consultationare considered to refer to those particulates less than 0.1 μm in diameter (PM0.1). Questions are often raised about the effect of nano- particles on human health and in particular on children’s health because of their high surface to volume ratio, making them more reactive and their very small size and the potential to penetrate cell walls of living organisms. The small size also means there will be a larger number of small particles for a given mass concentration. However the HPA statement (referenced below) says that due to the small effects of incinerators on local concentration of particles, it is highly unlikely that there will be detectable effects of any particular incinerator on local infant mortality

The Health Protection Agency (HPA) address the issue of the health effects of particulates in their September 2009 statement ‘The Impact on Health of Emissions to Air from Municipal Incinerators’. It refers to the coefficients linking PM10 and PM2.5 with effects on health derived by the Committee on the Medical Effects of Air Pollutants (COMEAP) and goes on to say that if these coefficients are applied to small increases in concentrations produced, locally, by incinerators, the estimated effects on health are likely to be small. The HPA notes that the coefficients that allow the use of number concentrations in impact calculations have not yet been defined because the national experts have not judged that the evidence is sufficient to do so. This is an area being kept under review by COMEAP.

Newhurst ERF Page 43 of 150 EPR/TP3036KP

The HPA also point out that in 2007 incinerators contributed 0.02% to ambient ground level PM10 levels compared with 18% for road traffic and 22% for industry in general. The HPA note that in a sample collected in a day at a typical urban area the proportion of PM0.1 is around 5-10% of PM10. It goes on to say that PM10 includes and exceeds PM2.5 which in turn includes and exceed PM0.1. This is borne out by the assessment of this Application which show emissions of PM10 to be insignificant

5.4 Impact on Habitats sites, SSSIs, non-statutory conservation sites etc.

5.4.1 Assessment of Likely Significant Effect on European Designated Habitat Sites and Ramsar Sites

There are no European Sites or Ramsars within 10km (our screening distance criteria) of the proposed installation and consequently we do not consider the installation will have any effect on European Sites or Ramsars

5.4.2 Assessment of the impact upon Sites of Special Scientific Interest (SSSI’s)

The Applicant assessed SSSI’s up to a distance of 10km from the Installation, however our screening distance criteria is 2km. Beyond 2km we do not consider that emissions from this type of process are likely to damage a SSSI, and we have not carried out any further assessment of the impacts on the sites beyond 2km. ThereDraft is only one SSSI For within 2km of the installation, and that is Newhurst Quarry (designation reference 1003050). The reasons for its notification are: Public “Newhurst Quarry is the only British site where pre-existing hypogene mineralisation, originating from ascending mineral-rich fluids in pre - Triassic times, has been notified by weathering and resedimentation during Triassic times, some 225Consultation million years ago. No other locality in Britain shows such effects, and Newhurst Quarry is the only British occurrence of the minerals Coulsonite (a vanadium-rich variety of magnetite) and Vesignieite (a complex hydrated copper-barium-vanadium mineral)”

This is purely a geological site and, from the citation, the features would not be eroded by acid deposition and so will not be impacted by emissions from the installation. The installation boundary is outside of the SSSI boundary, and so will not directly impact on the geological features either.

5.4.3 Impact upon Non-statutory Conservation Sites

We have a duty under the Environment Act 1995, to ensure that there will be no significant impact on non-statutory sites. The Environment Agency considers that the emission of a pollutant will not be significant if the process contribution (PC), predicted by atmospheric dispersion modelling, is less than 100% of the relevant critical level or load.

The Application includes an assessment of the impact of emissions from the proposed installation, using the BREEZE AERMOD dispersion model, upon local non statutory conservation sites in terms of atmospheric concentrations of NOx, SO2, Ammonia, acid deposition and nitrogen deposition.

Newhurst ERF Page 45 of 150 EPR/TP3036KP

The Applicant predicted the process contributions of nitrogen dioxide (NO2), ammonia (NH3) and sulphur dioxide (SO2) concentrations at the sites and compared them with their respective critical levels. The Applicant predictions are all less than 1% of the critical levels with the exception of Holywell Wood which is just over 1%. The Applicant used a critical level of 3µg/m3 for ammonia for some of these sites, a more precautionary figure to use would be 1µg/m3. Even using this figure for all sites the highest ammonia level will be at Holywell Wood and would be just 1.6% of the critical level.

The Applicant has calculated the nutrient nitrogen and acid deposition and compared the results to site relevant critical loads. The applicant predicts that the process contribution will be less than 1% of the critical loads with the exception of both Holywell Wood sites and Charnwell Lodge (nutrient nitrogen deposition) and both Holywell Wood sites, Grace Dieu/ High Sharpley, Charnwell Lodge, Bardon Hill, Benscliffe Wood and Beacon Hill (acid deposition).

As all predicted contributions and deposition rates are all well below 100% of the relevant critical levelsDraft we conclude that For the emissions from the installation will not cause significant of a pollution at these local non statutory conservation sites.

We have reviewed our ownPublic map data and have identified a further four Local Wildlife sites within 2km of the installation:

Site Name Grid ref. Designation Longcliffe Golf ConsultationCourse, SK 491 176 Local wildlife site, Lowland Penunculate Oak B Heathland Iveshead SK 480 170 Local wildlife site Morely Lane field SK 478 180 Local wildlife site, Hermitage Estate SK 493 197 Local Wildlife estate, Semi-Natural Broad-Leaved Wood

Nitrogen deposition and Acid deposition:

We modelled the Nitrogen deposition and Acid deposition at these sites and compared the resultsDraft to the critical loads forFor the sites taken from the UK Air Pollution Information System website (www.apis.ac.uk). We found that the deposition rates were well below the 100% threshold of the relevant critical load at any of the 4 sites Public Conclusion:

As all the predicted process contributions and the deposition rates discussed above, are belowConsultation 100% of the relevant Environmental Quality Standards, or critical levels/loads; we conclude that the emissions from the installation will not cause significant pollution at all non-statutory wildlife sites near to the installation.

5.5 Impact of abnormal operations

WID abnormal operations are defined as any technically unavoidable stoppages, disturbances, or failures of the abatement plant or the measurement devices, other than continuous emission monitors for releases to air of particulates, TOC and CO, during which the concentrations in the discharges into air may exceed the normal emission limit values.

WID abnormal operations are limited by the WID to no more 4 hours of continuous operation and no more than 60 hours in total in any calendar year. Abnormal operations could result in increased levels of emissions for short periods of time. These raised levels of emissions will not have a significant long-term impact on the environment as the period of abnormal operation is relatively short when compared with around 8,000 hours per year of total operating hours (i.e. <1%).

WID abnormal operations have the potential to have a greater short-term impact on the environment.Draft The Applicant Forhas considered that during periods of abnormal operation, emissions of pollutants would increase as follows:

Also from the table above none of the emissions not screened out as insignificant can be considered to have the potential to give rise to significant pollution in that the predicted environmental concentration is less than 100% of the short term EQS/EAL. For these emissions, we have carefully scrutinised the Applicant’s proposals to ensure that they are applying the Best Available Techniques to prevent and minimise emissions of these substances. This is reported in section 6 of this document.

5.5.2 Impact of dioxin abnormal conditions

In making an assessment of abnormal operations the following worst case scenario for Dioxin emissions of 10 ng/m3 (100 x normal) has been assumed. If dioxin emissions were at 10 ng/m3 for the maximum period of abnormal operation, this would result in a 70% increase in the TDI reported in section 5.3.2. In these circumstances the TDI figures would be:

Receptor Max predicted intake, COT TDI assuming abnormal operation Infant 0.22 2 Child 0.02 2 Adult 0.009 2 Farmer 0.026 2 Farm Child 0.05 2 Calculated maximum daily intake of dioxins by local receptors resulting from the operation of the proposed facility (pg TEQ/ kg-BW/day) Draft For In these circumstances the TDI figures would be would still not pose a risk to human health.

Public 5.6 Other Emissions

5.6.1 Discharge to Groundwater Consultation There will be no discharge to groundwater

5.6.2 Emissions to Surface Water

Clean surface water (rainwater) from roofs will be captured and stored in tanks within the building for use in the process. Water from roadways will be passed via silt and oil interceptors to a surface water attenuation pond, prior to discharge from the installation into Shortcliff Brook at emission point SW1 (as marked on the site plan in Schedule 7 of the Permit).

As this will be clean surface water, no emission limits have been set in the Permit for this discharge. Consequently this discharge is covered by conditions 3.2.1 and 3.2.2.

5.6.3 Discharge to Sewer

There will be a foul water connection to the sewer servicing welfare facilities, this discharge is not regulated by this Permit.

The Permit does not allow process water to be discharged to sewer. The Applicant does indicate that in the future they may want to discharge to sewer. However, as: • the exact nature of the discharge will be determined following commissioning,

Newhurst ERF Page 50 of 150 EPR/TP3036KP

• as they have not assessed the impact of a discharge to sewer, and • as they have not got a trade effluent agreement in place with the sewage undertaker, we have not permitted the discharge of process water to sewer. Instead the Applicant will have to apply for a variation to the Permit when they want to discharge process water to sewer. Until then any process water for discharge will be removed from the site via tanker to a suitably licensed facility

There will be no routine process water discharge from the installation under normal operating conditions. The plant is a net user of water and only when the plant is shutdown for annual maintenance will there be a need to discharge effluent or tanker it away.

6. Application of Best Available Techniques

6.1 Scope of Consideration

In this section, we explain how we have determined whether the Applicant’s proposals are the Best Available Techniques for this Installation.

• The first issue we address is the fundamental choice of incineration technology. There are a number of alternatives, and the Applicant has explained why it has chosen one particular kind for this Installation.

• We then consider control measures for the emissions which were not screened out as insignificant above. They are: - Oxides of Nitrogen - Sulphur Dioxide - Cadmium - Arsenic - Vanadium Draft For - Chromium(VI)

• We also have to consider the combustion efficiency and energy utilisation of different design optionsPublic for the Installation, which are relevant considerations in the determination of BAT for the Installation, including the Global Warming Potential of the different options.

• Finally, the Consultationprevention and minimisation of Persistent Organic Pollutants (POPs) must be considered, as we explain below.

6.1.1 Consideration of Furnace Type

The Applicant has carried out a review of the following candidate furnace types: • Moving Grate Furnace • Fixed Hearth • Pulsed Hearth • Rotary Kiln • Fluidised Bed • Pyrolysis / Gasification

The Operator carried out a qualitative assessment of the above technologies based on our Sector Guidance Note “The Incineration of Waste (EPR 5.01)” and the European BAT reference note. Their assessment was as follows:

• Moving Grate Furnaces: are designed to handle large volumes of waste. • Fixed Hearth: not considered suitable for large volumes of waste. They are best suited to low volumes of consistent waste. • Pulsed Hearth: has been used for municipal waste in the past, as well as other solid wastes. However, there have been difficulties in

Newhurst ERF Page 52 of 150 EPR/TP3036KP

achieving reliable and effective burnout of waste and it is considered that the burnout criteria required by WID would be difficult to achieve. • Rotary Kiln: have achieved good results with clinical waste but have not been used in the UK for MSW. The energy conversion efficiency of a rotary kiln is lower than that of a moving grate due to the large areas of refractory lined combustion chamber. An oscillating kiln is used for municipal waste at one site in England and a number of sites in France. The energy conversion efficiency is lower than that of a moving grate for the same reasons as for a rotary kiln. In addition, the capacity per unit is limited to 8tph and for this Application would need up to five number furnaces to achieve the design throughput, which is not economically feasible. • Pyrolysis/Gasification: various suppliers are developing pyrolysis and gasification systems for the disposal of municipal waste. However, it is not considered that any of these technologies can be considered to be proven. Pyrolysis and gasification systems which generate a syngas can theoretically take advantage of gas engines or gas turbines, which are more efficient that a standard steam turbine cycle. However, losses associated withD makingraft syngas Forand the additiona l electricity consumption of the site due to the waste pre-treatment requirements means that the overall efficiency is no higher than for combustion plant and is generally lower. This means that a combustion plant will generally have a morePublic beneficial effect on climate change. Plasma gasification can theoretically produce a much more useful syngas than thermal gasification, but has a much higher electrical parasitic load and is in the early stages of commercial development for municipal waste treatment.Consultation Therefore, pyrolysis and gasification are not considered to be suitable alternatives to the current facility design. • Fluidised Bed: designed for the combustion of relatively homogeneous waste. For residual MSW, the waste would need to be pre-treated before feeding to the fluidised bed, which would lead to additional energy consumption and a larger building. The pre-treatment can also lead to higher quantities of rejected material. Where MSW is treated at a material recycling facility, the residues from the MRF may already be suitable for feeding to the fluidised bed. This does not apply to residues from kerbside collection schemes, which would need some pre- treatment, including shredding and metals removal as a minimum, before feeding to the fluidised bed. While fluidised bed combustion can lead to slightly lower NOx generation, the injection of ammonia or urea is still required to achieve the emission limits specified in WID. Experience in the UK of fluidised bed combustion of MSW has been limited. Two plants are operational, but both have had significant operational problems. One is operating well below its design capacity while the other is still being commissioned. Biffa do not consider that they can be considered a reliable technology at this stage.

The prime function of the furnace is to achieve maximum combustion of the waste. The WID requires that the plant (furnace in this context) should be designed to deliver its requirements. The main requirements of the WID in

Newhurst ERF Page 53 of 150 EPR/TP3036KP

relation to the choice of a furnace are compliance with air emission limits for CO and TOC and achieving a low TOC/LOI level in the bottom ash.

The Waste Incineration BREF elaborates the furnace selection criteria as:

• the use of a furnace (including secondary combustion chamber) dimensions that are large enough to provide for an effective combination of gas residence time and temperature such that combustion reactions may approach completion and result in low and stable CO and TOC emissions to air and low TOC in residues. • use of a combination of furnace design, operation and waste throughput rate that provides sufficient agitation and residence time of the waste in the furnace at sufficiently high temperatures. • The use of furnace design that, as far as possible, physically retain the waste within the combustion chamber (eg grate bar spacing) to allow its complete combustion.

The BREF also provides a comparison of combustion and thermal treatment technologies and factorsDraft affecting their applicability For and operational suitability used in EU and for all types of wastes. There is also some information on the comparative costs. The table below has been extracted from the BREF tables. This table is also in line with the Guidance Note “The Incineration of Waste (EPR 5.01)”. However,Public it should not be taken as an exhaustive list nor that all technologies listed have found equal Application across Europe.

Overall, any of the furnace technologies listed above would be considered as BAT provided the ApplicantPublic has justified it in terms of: • nature/physical state of the waste and its variability • proposed plant throughput which may affect the number of incineration lines • preferenceConsultation and experience of chosen technology including plant availability • nature and quantity/quality of residues produced. • emissions to air – usually NOx as the furnace choice could have an effect on the amount of unabated NOx produced • energy consumption – whole plant, waste preparation, effect on GWP • Need, if any, for further processing of residues to comply with TOC • Costs

The Applicant has proposed to use a furnace technology using an air cooled moving grate comprising three lanes with five air-cooled zones or grate elements, which is identified in the tables above as being considered BAT in the BREF and TGN for this type of waste feed.

We have considered the assessments made by the Applicant and agree that the furnace technology chosen represents BAT. We believe that, based on the information gathered by the BREF process, the chosen technology will achieve the requirements of the WID for the air emission of TOC/CO and the TOC on bottom ash.

6.2 BAT and emissions control

The prime function of flue gas treatment is to reduce the concentration of pollutants in the exhaust gas to a level at which they will cause no significant environmental harm. The techniques which are described as BAT individually are targeted to remove specific pollutants, but the BREF notes that there is benefit from considering the FGT system as a whole unit. Individual units often interact, providing a primary abatement for some pollutants and an additional effect on others.

The BREF lists the general factors requiring consideration when selecting flue-gas treatment (FGT) systems as:

• type of waste, its composition and variation • type of combustion process, and its size • flue-gas flow and temperature • flue-gas content,D sizeraft and rate of fluctuations For in composition • target emission limit values • restrictions on discharge of aqueous effluents • plume visibility requirements • land and space availabilityPu blic • availability and cost of outlets for residues accumulated/recovered • compatibility with any existing process components (existing plants) • availability and cost of water and other reagents • energy Csupplyonsultatio possibilities (e.g. supply of heatn from condensing scrubbers) • reduction of emissions by primary methods • release of noise.

The Technical Guidance Note points to the following technologies being BAT:

6.2.1 Particulate Matter

The Applicant proposes to use fabric filters for the abatement of particulate matter. Fabric filters provide reliable abatement of particulate matter to below 5 mg/m3 and are BAT for most installations. The Applicant proposes to use multiple compartment filters, any failure of bags will be picked up by the CEM on the furnace stack.

Emissions of particulate matter have been previously been assessed as insignificant, and so the Environment Agency agrees that the Applicant’s proposed technique is BAT for the installation.

6.2.2 Oxides of Nitrogen

The Applicant proposes to implement the following primary measures:

Newhurst ERF Page 58 of 150 EPR/TP3036KP

• Low NOx burners – this technique reduces NOx at source and is defined as BAT where auxiliary burners are required. • Optimise primary and secondary air injection – this technique is BAT for all plant. • Flue gas recycling – this technique reduces the consumption of reagents for secondary NOx control and can increase overall energy recovery, although in some Applications there can be corrosion problems – the technique is considered BAT for all plant.

There are two recognised techniques for secondary measures to reduce NOx. These are Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR). For each technique, there is a choice of urea or ammonia reagent.

3 SCR can reduce NOx levels to below 70 mg/m and can be applied to all plant, it is generally more expensive than SNCR and requires reheating of the waste gas stream which reduces energy efficiency, periodic replacement of the catalysts also producesDraft a hazardous waste.For SNCR can typically reduce 3 NOx levels to between 150 and 180 mg/m , it relies on an optimum temperature of around 900 deg C and sufficient retention time for reduction. SNCR is more likely to have higher levels of ammonia slip. The technique can be applied to all plantPublic unless lower NOx releases are required for local environmental protection. Urea or ammonia can be used as the reagent with either technique, urea is somewhat easier to handle than ammonia and has a wider operating temperature window, but tends to result in higher emissions of

N2O. Either reagentConsultation is BAT.

The Applicant proposes to use SNCR with ammonia as the reagent.

Emissions of NOx cannot be screened out as insignificant. Therefore the Applicant has carried out a cost / benefit study of the alternative techniques, in “Appendix BATOT 12 Nitrogen Oxides Abatement Review”. The cost per tonne of NOx abated over the projected life of the plant has been calculated and compared with the environmental impact as shown in the table below.

Cost of NOx PC (long term) PEC (long term) removal £/tonne µg/m3 µg/m3 SNCR 6,610 1.15 31.8 SCR 9,106 0.76 31.4

The Applicant also concludes that:

• Both SCR and SNCR meet the mandatory requirements regarding emission limits. • SCR provides better NOx reduction but this has little or no significant improvement in the resulting ground-level concentrations. • Photochemical ozone creation potential (POCP) is lower with SCR, as a consequence of POCP being directly proportional to NOx.

Newhurst ERF Page 59 of 150 EPR/TP3036KP

• Global warming potential associated with SNCR is better than for SCR. This is due to the high level of additional heating required by SCR to maintain the catalyst in optimal condition; and • SCR generates an additional hazardous waste stream in the form of spent catalyst. This cannot be recovered, hence requires disposal in a hazardous waste landfill.

Based on the figures in the table above the Applicant considers that the additional cost of SCR over SNCR is not justified by the reduction in environmental impact. Thus SCR fails the availability test in BAT, and SNCR is BAT for the installation. The Applicant has justified the use of ammonia as the reagent on the basis that urea leads to relatively higher N2O emissions than ammonia. The Environment Agency agrees with this assessment.

The amount of ammonia used for NOx abatement will need to be optimised to maximise NOx reduction and minimise NH3 slip. Improvement condition IC5 requires the Operator to report to the Environment Agency on optimising the performance of the NOx abatement system. The Operator is also required to monitor and report onDraft NH3 and N2O emissions For every 6 months.

6.2.3 Acid Gases, SOx, HCl and HF Public The Applicant proposes to implement the following primary measures:

• Use of low sulphur fuels for start up and auxiliary burners – low sulphur

fuel oil willC be onsultationused, (i.e. <0.1% sulphur by mass), this will reduce SOx at source. • Management of problem wastes – this will disperse problem wastes such as PVC by ensuring an heterogeneous waste feed.

The Applicant has not specified the sulphur content of the gas oil, but we have specified this ,in table S2.1 of the Permit, as <0.1%. This will reduce SOx at source

There are three recognised techniques for secondary measures to reduce acid gases. These are wet, dry and semi-dry. Wet scrubbing produces an effluent for treatment and disposal in compliance with Article 8 of WID, it will also require reheat of the exhaust to avoid a visible plume. Wet scrubbing is unlikely to be BAT except where there are high acid gas and metal components in the exhaust gas as may be the case for some hazardous waste incinerators. In this case, the Applicant does not propose using wet scrubbing, and the Environment Agency agrees that wet scrubbing is not appropriate in this case.

The Applicant has therefore considered dry and semi-dry methods of secondary measures for acid gas abatement.

Both dry and semi-dry methods rely on the dosing of powdered materials into the exhaust gas stream. Semi-dry systems (i.e. hydrated reagent) offer

Newhurst ERF Page 60 of 150 EPR/TP3036KP

reduced material consumption through faster reaction rates, but reagent recycling in dry systems can offset this. Semi-dry systems may require plume reheat, which would reduce energy recovery.

In both dry and semi-dry systems, the injected powdered reagent reacts with the acid gases and is removed from the gas stream by the bag filter system. The powdered materials are either lime or sodium bicarbonate. Both are effective at reducing acid gases, and dosing rates can be controlled from continuously monitoring acid gas emissions. The decision on which reagent to use is normally economic. Lime produces a lower leaching solid residue in the APC residues than sodium bicarbonate and the reaction temperature is well suited to back filters, it tends to be lower cost, but it is a corrosive material and can generate a greater volume of solid waste residues than sodium bicarbonate. The choice of reagent is a finely balanced decision and Operator’s often prefer to have the capability to use either.

In this case, the Applicant proposes to use dry sodium bicarbonate, with recycling. As discussed above, reagent recycling in dry systems can offset the reduced materialDraft consumption of semi-dry For systems, and the dry system will not require plume re-heat. The Environment Agency is satisfied that this is BAT.

As discussed above, the ApplicantPublic has applied to use sodium bicarbonate but states that lime is an alternative which they may consider at the final design stage. Pre-operating condition, PO8, has been set for the Operator to send a report to the Environment Agency confirming which reagent they will be using, and, if it turns Consultationout to be Lime, to review the impact and BAT assessment to confirm that the use of Lime will not have a detrimental effect on the environment and will be considered BAT.

6.2.4 Carbon monoxide and volatile organic compounds (VOCs)

The prevention and minimisation of emissions of carbon monoxide and volatile organic compounds is through the optimisation of combustion controls, where all measures will increase the oxidation of these species.

6.2.5 Dioxins and furans

The prevention and minimisation of emissions of dioxins and furans is achieved through: • optimisation of combustion control including the maintenance of WID combustion conditions on temperature and residence time, which has been considered in 6.1.1 above; • avoidance of de novo synthesis, which has been covered in the consideration of boiler design; • the effective removal of particulate matter, which has been considered in 6.2.1 above; • injection of activated carbon. This can be combined with the acid gas reagent or dosed separately. Where the feed is combined, the combined feed rate will be controlled by the acid gas concentration in

Newhurst ERF Page 61 of 150 EPR/TP3036KP

the exhaust. Therefore, separate feed of activated carbon would normally be considered BAT unless the feed was relatively constant. Effective control of acid gas emissions also assists in the control of dioxin releases.

In this case the Applicant proposes separate feed and we are satisfied their proposals are BAT.

6.2.6 Metals

The prevention and minimisation of metal emissions is achieved through the effective removal of particulate matter, and this has been considered in 6.2.1 above.

Unlike others metal however, mercury if present will be present in vapour phase. BAT for mercury removal is also dosing of activated carbon into the exhaust gas stream. This can be combined with the acid gas reagent or dosed separately. WhereDraft the feed is co mbined,For the combined feed rate will be controlled by the acid gas concentration in the exhaust. Therefore, separate feed of activated carbon would normally be considered BAT unless the feed was relatively constant. Public In this case the Applicant proposes separate feed and we are satisfied their proposals are BAT.

Consultation 6.2.7 Flue gas treatment plant bypass

The Application states that the flue gas treatment plant will be bypassed “as necessary” during start up and shut downs. The justification for this was clarified in the response to a schedule 5 notice dated 12 December 2010. During cold start-up or shut-down, the temperature of the flue gas can temporarily drop below the dew point. The presence of cold, humid conditions may lead to the acid dew-point of the flue gases being reached, conditions that can lead to corrosion of gas ducting and steelwork. For this reason the FGT stage is by-passed at these times. This bypass will occur before any waste is charged at start up, or after all the waste has been burnt on shut down. Further justification was provided by the Applicant who stated that the by-pass will only be open during start up until the boiler flue gas outlet reaches a temperature of 120oc after which it will remain closed. The by-bass will only re-open at shut down when the boiler flue gas outlet temperature reaches 120oc. This has been added as Permit condition 2.3.13.

The environmental impact of by-passing the FGT stage is considered to be minimal. Indicative BAT standards in sector guidance note EPR 5.01 states that an abatement bypass may be operated at start up to prevent damage to abatement plant.

Newhurst ERF Page 62 of 150 EPR/TP3036KP

6.3 BAT and global warming potential

This section summarises the assessment of greenhouse gas impacts which has been made in the determination of this Permit. Emissions of carbon dioxide (CO2) and other greenhouse gases differ from those of other pollutants in that, except at gross levels, they have no localised environmental impact. Their impact is at a global level and in terms of climate change. Nonetheless, CO2 is clearly a pollutant for IPPCD purposes.

The principal greenhouse gas emitted is CO2, but the plant also emits small amounts of N2O arising from the operation of secondary NOx abatement. N2O has a global warming potential 310 times that of CO2. The Applicant will therefore be required to optimise the performance of the secondary NOx abatement system to ensure its GWP impact is minimised.

The major source of greenhouse gas emissions from the installation is however CO2 from the combustion of waste. There will also be CO2 emissions from the burningDraft of support fuels For at start up, shut down and should it be necessary to maintain combustion temperatures. BAT for greenhouse gas emissions is to maximise energy recovery and efficiency.

The electricity that is generatPubliced by the Installation will result in a reduction in emissions of CO2 elsewhere in the UK, as virgin fossil fuels will not be burnt to create the same electricity. GWP calculations therefore need to include a CO2 offset for the net amount of electricity exported from the Installation. Consultation The Applicant used the Environment Agency’s H1 tool to calculate the gross GWP from burning waste and gas oil as 195,000 tonnes of CO2 per annum. They also used the WRATE model, but we consider that our H1 tool provided for this purpose is the most appropriate for this purpose.

Using conversion factors taken from our H1 horizontal guidance note (annex H, table B1), the CO2 offset by the exporting of 25.8MWe, or 201,000MWh per year, can be calculated by multiplying by an efficiency conversion factor of 2.4 and a tonnes CO2 per MWh factor of 0.166. This gives a GWP of 80,000 tonnes of CO2 per annum.

Taking this into account, the net emissions of CO2 from the installation are estimated at around 115,000 tonnes per annum. At this level emissions cannot be characterised as insignificant. The Installation is not subject to the Greenhouse Gas Emissions Trading Scheme Regulations 2003; therefore it is a requirement of IPPCD to investigate how emissions of greenhouse gases emitted from the installation might be prevented or minimised.

The Applicant has considered GWP as part of their BAT options appraisal. There are a number of areas in which a difference can be made to the GWP of the Installation, e.g. The Applicant’s BAT options appraisal compared SCR and SNCR methods of secondary NOx abatement. In summary: the following factors influence the GWP of the facility:-

Newhurst ERF Page 63 of 150 EPR/TP3036KP

On the debit side • CO2 emissions from the burning of the waste; • CO2 emissions from burning auxiliary or supplementary fuels; • CO2 emissions associated with electrical energy drawn from the public supply: • CO2 from the de-NOx process. • N2O from the de-NOx process.

On the credit side • CO2 saved from the export of electricity to the public supply by displacement of burning of virgin fuels; • CO2 saved from the use of waste heat by displacement of burning of virgin fuels.

The Applicant’s assessment shows that the GWP of the plant is dominated by the emissions of carbon dioxide that are releases as a result of waste combustion. This Draftis constant for all Foroptions considered in the BAT assessment.

Taking all these factors into account, the Operator’s assessment shows their preferred option (SNCR) is Publicbest in terms of GWP.

The Environment Agency agrees with this assessment and that the chosen option is BAT for the installation. Consultation

6.4 BAT and POPs

International action on Persistent Organic pollutants (POPs) is required under the UN’s Stockholm Convention, which entered into force in 2004 and has been signed by 151 nations. The EU implemented the Convention through the POPs Regulation (850/2004), which is directly applicable in UK law. The Agency is required by national POPs Regulations (SI 2007 No 3106) to give effect to Article 6(3) of the EC POPs Regulation when determining Applications for environmental Permits. However, it needs to be borne in mind that this Application is for a particular type of installation, namely a waste incinerator.

The Stockholm Convention distinguishes between intentionally- and unintentionally-produced POPs. Intentionally-produced POPs are those used deliberately (mainly in the past) in agriculture (primarily as pesticides) and industry. Those intentionally-produced POPs are not relevant where waste incineration is concerned. This is logical, not least because high-temperature incineration is one of the prescribed methods for destroying POPs.

The unintentionally-produced POPs addressed by the Convention are: • dioxins and furans; • HCB; and

Newhurst ERF Page 64 of 150 EPR/TP3036KP

• PCBs. • PeCB

The UK’s national implementation plan for the Stockholm Convention, published in 2007, makes explicit that the relevant controls for unintentionally- produced POPs, such as might be produced by waste incineration, are delivered through a combination of IPPC and WID requirements. That would, as required by the IPPC Directive, include an examination of BAT, including potential alternative techniques, with a view to preventing or minimising harmful emissions. These have been applied as explained in this document, which explicitly addresses alternative techniques and BAT for the minimisation of emissions of dioxins.

Our legal obligation, under regulation 4(b) of the POPs Regulations, is, when considering an Application for an environmental permit, to comply with article 6(3) of the POPs Regulation:

“Member States shall, when considering proposals to construct new facilities or significantly Draftto modify existing facilitiesFor using processes that release chemicals listed in Annex III, without prejudice to Council Directive 1996/61/EC, give priority consideration to alternative processes, techniques or practices that have similar usefulness but which avoid the formation and release of substancesPublic listed in Annex III.”

We believe that the Permit ensures that the formation and release of POPs will be prevented or minimised. As we explain above, high-temperature incineration is Consultationone of the prescribed methods for destroying POPs. The requirements of the Stockholm Convention in relation to unintentionally- produced POPs are delivered through the IPPCD and the WID, which require the use of BAT to prevent or, where that is not possible, minimise all harmful emissions, including POPs.

The release of dioxins and furans to air is required by the WID to be assessed against the I-TEQ (International Toxic Equivalence) limit of 0.1 ng/m3. Further development of the understanding of the harm caused by dioxins has resulted in the World Health Organisation (WHO) producing updated factors to calculate the WHO-TEQ value. Certain PCBs have structures which make them behave like dioxins (dioxin-like PCBs), and these also have toxic equivalence factors defined by WHO to make them capable of being considered together with dioxins. The UK’s independent health advisory committee, the Committee on Toxicity of Chemicals in Food, Consumer Products and the Environment (COT) has adopted WHO-TEQ values for both dioxins and dioxin-like PCBs in their review of Tolerable Daily Intake (TDI) criteria. The Government is of the opinion that, in addition to the requirements of the WID, the WHO-TEQ values for both dioxins and dioxin- like PCBs should be specified for monitoring and reporting purposes, to enable evaluation of exposure to dioxins and dioxin-like PCBs to be made using the revised TDI recommended by COT. The release of dioxin-like PCBs and PAHs is expected to be low where measures have been taken to control dioxin releases. The Secretary of State has directed regulators to

Newhurst ERF Page 65 of 150 EPR/TP3036KP

require monitoring of a range of PAHs and dioxin-like PCBs in waste incineration Permits at the same frequency as dioxins are monitored. We have included a requirement to monitor and report against these WHO-TEQ values for dioxins and dioxin-like PCBs and the range of PAHs identified by Defra in the Environmental Permitting Guidance on the WID. We are confident that the measures taken to control the release of dioxins will also control the releases of dioxin-like PCBs and PAHs. Section 5.3 of this document details the assessment of emissions to air, which includes dioxins and concludes that there will be no adverse effect on human health from either normal or abnormal operation.

Hexachlorobenzene (HCB) is addressed by the European Environment Agency (EEA), which advises that:

"due to comparatively low levels in emissions from most (combustion) processes special measures for HCB control are usually not proposed. HCB emissions can be controlled generally like other chlorinated organic compounds in emissions, for instance dioxins/furans and PCBs: regulationDraft of time of combustion, For combustion temperature, temperature in cleaning devices, sorbents Application for waste gases cleaning etc." [reference http://www.eea.europa.eu/publications/EMEPCORINAIR4/sources_of_ HCB.pdf] Public

We have assessed the control techniques proposed for dioxins by the Applicant and have concluded that they are appropriate for dioxin control. We are confident thatConsultation these controls will also minimise the release of HCB.

Pentchlorobenzene (PeCB) has been used as a fungicide or flame retardant, there is no data available however on production, recent or past, outside the UN-ECE region. In the Stockholm Convention Protocols several emission control techniques are given which will also lead to a reduction of PeCB emissions: Annex V (Best Available Techniques to control emissions of persistent organic pollutants from major stationary sources): PeCBs can be emitted from the same sources as described for PCDD/F in Annex V: waste incineration, thermal metallurgic processes and combustion plants providing energy. The approaches described in Annex V to control the emissions of PCDD/F will subsequently also lead to a reduction of the emissions of PeCBs.

We have assessed the control techniques proposed for dioxins by the Applicant and have concluded that they are appropriate for dioxin control. We are confident that these controls will also minimise the release of HCB, PCB and PeCB.

We are therefore satisfied that the substantive requirements of the Convention and the POPs Regulation have been addressed and complied with.

Newhurst ERF Page 66 of 150 EPR/TP3036KP

6.5 Other Emissions to the Environment

6.5.1 Emissions to water

Clean surface water (rainwater) from roofs will be captured and stored in tanks within the building for use in the process. Water from roadways will be passed via silt and oil interceptors to a surface water attenuation pond, prior to discharge from the installation into Shortcliff Brook.

Based upon the information in the Application we are satisfied that appropriate measures will be in place to prevent and /or minimise emissions to water.

6.5.2 Emissions to sewer

There will be a foul water connection to the sewer servicing welfare facilities, this discharge is not regulated by this Permit, and will require a separate Application from the Applicant.Draft For

The Permit does not allow process water to be discharged to sewer. Any process water for discharge will be removed from the site via tanker to a suitably licensed facility. Public

6.5.3 Fugitive emissions Consultation The WID specifies that plants must be designed in such a way as to prevent the unauthorised and accidental release of polluting substances into soil, surface water and groundwater. In addition storage requirements for contaminated water of Article 8(7) must be arranged.

The Operator describes the proposed measures preventing fugitive emissions to soil, surface water and groundwater, in section 4.10 of the Application’s “Best Available Techniques and Operating Techniques (BATOT) statement”. Key aspects of which are described below:

Storage of waste will occur only in the waste reception hall on an impermeable surface served by a sealed drainage system.

Materials will be stored indoors in designated, bunded areas to minimise environmental risks. These areas will be clearly marked and maximum storage capacities clearly stated. Regular checks and audits will ensure that storage areas are well maintained. Access to storage areas will be designed to minimise risks of collisions and spillages.

The site surfacing and drainage system will be designed to minimise potential losses of contaminants to surface and groundwater. Key areas in which hazardous materials will be handled will be provided with extra protection,

Newhurst ERF Page 67 of 150 EPR/TP3036KP

such as kerbing and bunding, and all parts of the installation will be subject to regular visual inspection to maintain integrity.

Bulk liquid storage tanks, such as those containing fuel oil, will be in dedicated and isolated bunds. All bunds will have a capacity greater than 110 percent of the largest tank or 25 percent of the total tankage, whichever is the larger.

Based upon the information in the Application we are satisfied that appropriate measures will be in place to prevent and/or minimise fugitive emissions.

6.5.4 Odour

The proposed facility will be enclosed within a purpose-built building. The waste storage bunker will be located within the waste reception hall which will be enclosed with access doors and air louvers to manage traffic and air movements. Air willDraft be extracted from Forthe waste reception hall for the combustion process thus creating an airflow direction into the building minimising the escape of odour.

Bunker management proceduresPublic will be in place to ensure that periodic emptying and cleaning takes place to avoid the development of anaerobic conditions developing within the waste.

The facility will Consultationoperate continuously on a 24-hour, seven days per week basis meaning waste is stored for the minimal possible period of time prior to incineration. Two incineration lines are proposed ensuring that when one line is out of action for maintenance the other line will continue to operate, which the Applicant states will ensure waste will not be allowed to build up within the reception hall.

Ash produced by the facility is quenched, producing a wet ash by-product. This will have an odour, but the Operator considers this to be insignificant in the context of the site setting and potential sensitive receptors within a reasonable distance that could be affected by the odour (i.e. adjacent to the M1 motorway and distance from residential receptors). Water will be sprayed onto the ash to maintain correct conditions for maturation and prevent fugitive dust emissions, in line with BAT.

Based upon the information in the Application we are satisfied that the appropriate measures will be in place to minimise and prevent pollution from odour.

Newhurst ERF Page 68 of 150 EPR/TP3036KP

6.5.5 Noise and vibration

Based upon the information in the Application we are satisfied that the appropriate measures will be in place to prevent pollution from noise and vibration.

The Application contained a noise impact assessment which identified local noise-sensitive receptors, potential sources of noise at the proposed plant and noise attenuation measures. Measurements were taken of the prevailing ambient noise levels to produce a baseline noise survey and an assessment was carried out in accordance with BS4142 to compare the predicted plant rating noise levels with the established background levels.

The Applicants assessment concluded that:

• predicted daytime and night-time noise rating levels produced by fixed plant at the proposedDraft development woulFord give a positive indication that complaints are unlikely at all of the nearest noise-sensitive receptors assessed, • the cumulative impact of all operations would have no effect on the existing ambient noiseP levelsublic at any of the nearest noise-sensitive receptors assessed.

We audited the Applicants model, and found that the modelling was flawed. The Applicant Consultationdid not have the design details for the room dimensions, what the walls and roofs will be made out of (affects sound absorption) and what the sound power levels and quantity of machinery will be in each room. Without these fundamental parameters it was impossible for us to verify the Applicant’s conclusion. This information was requested from the Applicant, but as the plant is not at the final design stage they could not provide this information. Consequently pre-operating condition PO4 has been set requiring the submission of a revised noise assessment with all the missing information, to enable to us to verify the Applicant’s conclusions before the facility is operated. We are satisfied that, based upon the information in the Application, the appropriate measures will be in place to prevent pollution from noise and vibration and that revised assessment should confirm this. If the revised assessment does not confirm this, then it will enable further measures to be taken to prevent pollution from noise and vibration.

Public comments were also received on the existence of nesting Peregrine Falcons, as discussed in Annex 4. The existence of Falcons has not been confirmed. The noise assessment does not assess the quarry face as a location of a sensitive receptor, and so for completeness pre-operating condition PO4 requires the assessment of noise impacts on potential nesting sites within the quarry.

Newhurst ERF Page 69 of 150 EPR/TP3036KP

6.6 Setting ELVs and other Permit conditions

6.5.1 Translating BAT into Permit conditions

The use of WID limits for air dispersion modelling sets the worst case scenario. If this shows emissions are insignificant then we accept that the Applicant’s proposals are BAT, and that there is no justification to reduce ELVs below WID levels in these circumstances.

Below we consider whether, for those emission not screened out as insignificant, different conditions are required as a result of consideration of local or other factors.

(i) Local factors

We have considered the following information: • poor air quality • concerns aboutD localraft health For

The impact on air quality and the risks to human health are discussed in detail in section 5.2 and 5.3 of this document respectively. Public (ii) National and European EQSs

In determining this Permit, the Environment Agency has had regard to the Air Quality StrategyConsultation for England, Scotland, Wales and Northern Ireland. This has been considered by using the relevant Air Quality Objectives as part of the air quality assessment in section 5.2 of this document.

We have also taken into account relevant air quality limit and target values set out in the EC Air Quality Framework Directive & Daughter Directives.

The Environment Agency considers that it has taken its decision in compliance with the Air Quality Strategy and EU Directives, and that there are no additional conditions that should be included in this Permit.

(iii) Global Warming

CO2 is an inevitable product of the combustion of waste. The amount of CO2 emitted will be essentially determined by the quantity and characteristics of waste being incinerated, which are already subject to conditions in the Permit. It is therefore inappropriate to set an emission limit value for CO2, which could do more than recognise what is going to be emitted. The gas is not therefore targeted as a key pollutant under the IPPC Directive or under the Waste Incineration Directive, e.g. it is not included in Annex III to the IPPCD, which lists the main polluting substances that are to be considered when setting emission limit values (ELVs) in Permits.

Newhurst ERF Page 70 of 150 EPR/TP3036KP

We have therefore considered setting equivalent parameters or technical measures for CO2. However, provided energy is recovered efficiently (see section 4.3.7 above), there are no additional equivalent technical measures (beyond those relating to the quantity and characteristics of the waste) that can be imposed that do not run counter to the primary purpose of the plant, which is the destruction of waste. Controls in the form of restrictions on the volume and type of waste that can be accepted at the Installation and permit conditions relating to energy efficiency effectively apply equivalent technical measures to limit CO2 emissions.

(iv) Commissioning

As the proposed facility is still at the early design stage the Operator has not given full details of their commissioning plans or how they propose to validate the combustion conditions to demonstrate compliance with the WID. Thus the following commissioning pre-operating and improvement conditions have been set in the permit:

Pre-operating condition,Draft PO5, has been Forset to ensure that the Operator provides the Environment Agency of their plan for the commissioning of the installation, for us to approve. Commissioning will then take place in accordance with the approved plan. Public Pre-operating condition PO7 has been set to requiring a report that demonstrates that the indicative BAT, for the validation of combustion conditions, for “operational stage”, “qualifying zone” and “test conditions” requirements, Consultationgiven in section 2.5 of the Incineration of Waste Sector Guidance note EPR 5.01, will be applied during commissioning.

Improvement condition, IC4, has been set to ensure that the Operator submits a report to the Environment Agency on the commissioning of the installation. The report shall summarise the environmental performance of the plant as installed against the design parameters set out in the Application. The report shall also include a review of the performance of the facility against the conditions of this permit and details of procedures developed during commissioning for achieving and demonstrating compliance with permit conditions.

6.7 Monitoring

6.7.1 Monitoring during normal operations

We have decided that monitoring should be carried out for the parameters listed in tables S3.1 to S3.4 in Schedule 3 of the Permit using the methods and to the frequencies specified in those tables. These monitoring requirements have been imposed in order to demonstrate compliance with emission limit values.

Newhurst ERF Page 71 of 150 EPR/TP3036KP

For emissions to air, the methods for continuous and periodic monitoring are in accordance with the Agency’s Guidance M2 for monitoring of stack emissions to air.

The ammonia monitor will be certified to MCERTS although no emission limit value has been set at this time. Monitoring of N2O and ammonia have been set as a requirement of the permit to demonstrate the optimum environmental performance of the NOx abatement process.

Based on the information in the Application and the requirements set in the conditions of the permit we are satisfied that the Operator’s techniques, personnel and equipment will have either MCERTS certification or MCERTS accreditation as appropriate.

6.7.2 Monitoring under abnormal operations arising from the failure of the installed CEMs

The Operator will provide standby CEMS working in parallel to the operating CEMS. These will beDraft switched into full operationFor immediately in the event that there is any failure in the regular monitoring equipment. The standby CEMS measure the same parameters as the operating CEMS. In the unlikely event that both CEMS fail, condition 2.3.10 of the permit requires that the WID abnormal operating conditionsPublic apply.

6.7.3 Other Monitoring Requirements

Other monitoringConsultation requirements have been set by the Environment Agency in Condition 3.5.1 and Schedule 3 of the permit. These monitoring requirements have been imposed in order to enable correction of measured concentration of substances to the appropriate reference conditions; to gather information about the performance of the SNCR system; to deliver guidance from DEFRA that dioxin-like PCBs and PAHs should be monitored and to deliver the requirements of WID for monitoring of residues and temperature in the combustion chamber.

In addition improvement condition IC2 requires an exercise be carried out to determine the size distribution of the particles emitted from the stacks to identify the fractions in the PM10, PM2.5 and PM1.0 ranges. This reflects the latest scientific research which indicates that very fine particles have the most potential to adversely affect health. This is a standard improvement condition being imposed on all incinerators in order to gather information on the contribution of waste incineration generally to emissions of very fine particles.

6.7.4 Continuous emissions monitoring for dioxins and mercury

The WID specifies manual extractive sampling for mercury and dioxin monitoring. The Environment Agency has reviewed the applicability of these techniques to the installation.

Newhurst ERF Page 72 of 150 EPR/TP3036KP

Until recently there was no CEM which could measure solid phase (particulate) mercury as well as vapour phase mercury. However there are now instruments which claim to measure total mercury such as the MERCEM instrument manufactured by Sick-Maihak, which is CEMS certified. The Committee European de Normalisation (CEN) has recently published a standard for total mercury to be determined by automated measuring systems (EN 14884:2005). However the British Standards Institute has objected to manner in which the standard has been developed and believes it does not entirely fulfil its purpose.

In the case of dioxins, the equipment is capable of taking a sample for an extended period (several weeks), but the sample must then be analysed in the conventional way. Despite good ability to track the same trends in changing dioxin concentrations, systematic differences are observed between continuous sampling and manual sample train measurements in which continuous sampling records dioxin concentrations higher than manual sample trains. The lack of a primary reference method (e.g. involving a reference gas of know concentration of dioxin) prohibits any one approach being considered moreDraft accurate than anot Forher. Manual sample trains are more applicable for dioxin monitoring against an emission limit value in accordance with WID requirements where dioxin methods are required to meet EN1948. Cross-stack sampling in accordance wih EN13284-1 (the low dust standard) is a pre-requisitePublic of EN1948, whereas continuous sampling techniques are designed for operation at one or at most two fixed points across the stack.

For either continuousConsultation monitoring or sampling to be used for regulatory purposes, an emission limit value would need to be devised which is applicable to continuous monitoring. Such limits for mercury and dioxins have not been set by the European Commission and this makes it difficult for the Agency to act unilaterally in the case of UK incinerators. Use of a manual sample train is the only technique which fulfils the requirements of the WID. At the present time, it is considered that in view of the predicted low levels of mercury and dioxin emission it is not justifiable to require the Operator to install continuous monitoring for these substances.

In accordance with it’s legal requirement to do so the Environment Agency is always reviewing the development of new methods and standards and their performance in industrial Applications. In particular the Environment Agency considers continuous sampling systems for dioxins to have promise as a potential means of improving process control and obtaining more accurate mass emission estimates. In any event, we will require continuous measurement of dioxins and mercury should the European Commission introduce this under Article 11(13) of the WID.

6.8 Reporting

We have specified the reporting requirements in Schedule 5 of the Permit either to meet the reporting requirements set out in the WID, or to ensure data

Newhurst ERF Page 73 of 150 EPR/TP3036KP

is reported to enable timely review by the Environment Agency to ensure compliance with permit conditions and to monitor the efficiency of material use and energy recovery at the installation.

Draft For Public

Consultation

Newhurst ERF Page 74 of 150 EPR/TP3036KP

7 Other legal requirements

In this section we explain how we have addressed other relevant legal requirements, to the extent that we have not addressed them elsewhere in this document.

7.1 The EPR 2010 and related Directives

The EPR delivers the requirements of a number of European and national laws.

7.1.1 Schedules 1 and 7 to the EPR 2010 – IPPC Directive

We address the requirements of the IPPCD in the body of this document above.

There is one requirementDraft not addressed Forabove, which is that contained in Article 9(2) IPPCD. Article 9(2) of the IPPC Directive requires that “In the case of a new installation or a substantial change where Article 4 of Directive 85/337/EC applies, any relevant information obtained or conclusion arrived at pursuant to articles 5, 6 andPublic 7 of that Directive shall be taken into account for the purposes of granting an environmental permit. • Article 5 of EIA Directive relates to the obligation on developers to supply the information set out in Annex IV of the Directive when making an ApplicationConsultation for development consent. • Article 6(1) requires Member States to ensure that the authorities likely to be concerned by a development by reason of their specific environmental responsibilities are consulted on the Environmental Statement and the request for development consent. • Article 6(2)-6(6) makes provision for public consultation on Applications for development consent. • Article 7 relates to projects with transboundary effects and consequential obligations to consult with affected Member States.

The grant or refusal of development consent is a matter for the relevant local planning authority. The Environment Agency’s obligation is therefore to take into consideration any relevant information obtained or conclusion arrived at by the local planning authorities pursuant to those EIA Directive articles.

In determining the Application we have considered the following documents: - • The Environmental Statement submitted with the planning Application (which also formed part of the Environmental Permit Application). • The decision of Leicestershire County Council to refuse planning permission on 20 October 2010. • The Development Control and Regulatory Board 15th October 2010 Report of the Chief Executive report of Leicestershire County Council which recommended refusal of planning permission.

Newhurst ERF Page 75 of 150 EPR/TP3036KP

• The response of the Environment Agency to the local planning authority in its role as consultee to the planning process.

We have reviewed the reasons given for the refusal of planning permission and specifically whether this conclusion is based on information given in the Environmental Statement. We are satisfied that these matters are entirely matters of planning policy and not relevant to our determination. The Government’s Planning Policy Statements Nos. 10 and 23 make it clear that the pollution control and planning regimes are intended to be complementary and should avoid duplication.

From our consideration of all the documents above, the Environment Agency considers that no additional or different conditions are necessary.

The Environment Agency has also carried out its own consultation on the Environmental Permitting Application which includes the Environmental Statement submitted to the local planning authority. The results of our consultation are described elsewhere in this decision document. Draft For 7.1.2 Schedule 9 to the EPR 2010 – Waste Framework Directive

As the Installation involves the treatment of waste, it is carrying out a waste operation for the purposesPublic of the EPR 2010, and the requirements of Schedule 9 therefore apply. This means that we must exercise our functions so as to ensure implementation of certain articles of the Directive 2006/12/EC, as well as other specified requirements. Consultation Directive 2006/12/EC has been repealed and replaced by Directive 2008/98/EC. We anticipate the references in Schedule 9 will have been updated by the time any final decision is made on the Application. However, for completeness at this time we address both Directives. We address 2006/12/EC first as that is the one currently referenced in Schedule 9.

We must give effect to Article 4 which requires that waste is recovered or disposed of without endangering human health and without using processes or methods which could harm the environment, and in particular: (a) without risk to water, air or soil, or to plants or animals; (b) without causing a nuisance through noise or odours; (c) without adversely affecting the countryside or places of special interest.

We have addressed these objectives elsewhere in this document. The conditions of the Permit protect the environment and ensure that there is no harm to any features identified above.

Schedule 9 also requires that records referred to under Article 14 are kept and made available to the Environment Agency on request. Conditions relating to the collection, maintenance, storage and availability of records form part of the Permit.

Newhurst ERF Page 76 of 150 EPR/TP3036KP

We are also required to give effect, where disposal operations are involved, to Article 5, which requires that appropriate measures are taken to establish an integrated and adequate network of disposal installations, taking account of the best available technology not involving excessive costs. The network must enable the Community as a whole to become self-sufficient in waste disposal and the Member States to move towards that aim individually, taking into account geographical circumstances or the need for specialised installations for certain types of waste. This network must enable waste to be disposed of in one of the nearest appropriate installations, by means of the most appropriate methods and technologies in order to ensure a high level of protection for the environment and public health.

Waste planning is primarily the responsibility of the Waste Disposal Authority and the Local Authority. In determining this Application we have had regard to the Government’s Waste Strategy, we have also considered Planning Policy Statement 10: Planning for Sustainable Waste Management (PPS10). We have also had regard to the waste policies of the Local Authority as set out in their Local Development Framework. Draft For We note that planning permission has been refused by the council. The decision is based on planning matters rather than waste strategy or pollution control issues. We are satisfied that the Application is in compliance with Article 5. The proposed facilityPublic will have no significant adverse impact on the environment or human health and it can make a contribution towards an integrated network of disposal facilities taking account of best available techniques. Consultation In addition, Schedule 9 requires the Environment Agency, in relation to disposal operations: (b) to implement, so far as material, any waste management plan; and (c) to ensure that the permit covers: (i) the types and quantities of waste; (ii) the technical requirements; (iii) the safety precautions to be taken; (iv) the disposal site; (v) the treatment method.

The matters referred to in paragraph (c) above are addressed through Permit conditions. By granting a Permit, the Environment Agency is satisfied that it will support the waste management plan.

Turning to Directive 2008/98/EC we anticipate by the time any decision is finalised we will have to consider the obligations which follow in place of those set out above.

We should exercise our relevant functions for the purposes of ensuring that the waste hierarchy referred to in Article 4 is applied to the generation of waste and that any waste generated is treated in accordance with Article 4.

Newhurst ERF Page 77 of 150 EPR/TP3036KP

The conditions of the Permit ensure that waste generation from the facility is minimised. Where the production of waste cannot be prevented it will be recovered wherever possible or otherwise disposed of in a manner that minimises its impact on the environment. This is in accordance with Article 4.

Also that we exercise our relevant functions for the purposes of implementing Article 13; ensuring that the requirements in the second paragraph of Article 23(1) are met; and ensuring compliance with Articles 18(2)(b), 18(2)(c), 23(3), 23(4) and 35(1).

Article 13 relates to the protection of human health and the environment. These objectives are addressed elsewhere in this document.

Article 23(1) requires the permit to specify: (a) the types and quantities of waste that may be treated; (b) for each type of operation permitted, the technical and any other requirements relevant to the site concerned; (c) the safety and precautionary measures to be taken; (d) the methodDra to be used forft each typeFor of operation; (e) such monitoring and control operations as may be necessary; (f) such closure and after-care provisions as may be necessary.

These are all covered by permitPub conditions.lic

The Permit does not allow hazardous waste to be accepted, nor does it allow hazardous APC residues to be mixed with non hazardous IBA (as the

Application’s operatingConsultation techniques are incorporated into the Permit via condition 2.3.1 and table S1.2). Consequently Article 18 is not relevant.

We consider that the intended method of waste treatment is acceptable from the point of view of environmental protection so Article 23(3) does not apply. Energy efficiency is dealt with elsewhere in this document but we consider the conditions of the permit ensure that the recovery of energy take place with a high level of energy efficiency in accordance with Article 23(4).

Article 35(1) relates to record keeping and its requirements are delivered through permit conditions.

7.1.3 Schedule 13 to the EPR 2010 – Waste Incineration Directive

We address the WID in detail in Annex 1 to this document.

7.1.4 Schedule 22 to the EPR 2010 – Groundwater, Water Framework and Groundwater Daughter Directives

To the extent that it authorises the discharge of pollutants to groundwater (a “groundwater activity” under the EPR 2010), the Permit is subject to the

Newhurst ERF Page 78 of 150 EPR/TP3036KP

requirements of Schedule 22, which delivers the requirements of EU Directives relating to pollution of groundwater. The Permit will require the taking of all necessary measures to prevent the input of any hazardous substances to groundwater, and to limit the input of non-hazardous pollutants into groundwater so as to ensure such pollutants do not cause pollution, and satisfies the requirements of Schedule 22.

No releases to groundwater from installation are permitted. The Permit also requires material storage areas to be designed and maintained to a high standard to prevent accidental releases.

7.1.5 Directive 2003/35/EC – The Public Participation Directive

Regulation 59 of the EPR 2007 requires the Agency to prepare and publish a statement of its policies for complying with its public participation duties.

The Environment Agency has published such a document and this Application is being consulted uponDraft in line with our public For participation statement, as well as with the Agency’s RGS6 on Sites of High Public Interest, which addresses specifically extended consultation arrangements for determinations where public interest is particularly high. This satisfies the requirements of the Public Participation Directive.Public

Our draft decision in this case has been reached following a programme of extended public consultation, both on the original Application and later, separately, on Consultationthe draft permit and a draft decision document. The way in which this has been done is set out in Section 2. A summary of the responses received to our consultations and our consideration of them is set out in Annex 4.

7.2 National primary legislation

7.2.1 Environment Act 1995

(i) Section 4 (Pursuit of Sustainable Development)

We are required to contribute towards achieving sustainable development, as considered appropriate by Ministers and set out in guidance issued to us. The Secretary of State for Environment, Food and Rural Affairs has issued The Environment Agency’s Objectives and Contribution to Sustainable Development: Statutory Guidance (December 2002). This document: “provides guidance to the Agency on such matters as the formulation of approaches that the Agency should take to its work, decisions about priorities for the Agency and the allocation of resources. It is not directly applicable to individual regulatory decisions of the Agency”. In respect of regulation of industrial pollution through the EPR, the Guidance refers in particular to the objective of setting permit conditions “in a consistent and proportionate fashion based on Best Available Techniques and taking into account all relevant matters…”. The Environment Agency considers that it

Newhurst ERF Page 79 of 150 EPR/TP3036KP

has pursued the objectives set out in the Government’s guidance, where relevant, and that there are no additional conditions that should be included in this Permit to take account of the Section 4 duty.

(ii) Section 7 (Pursuit of Conservation Objectives)

We considered whether we should impose any additional or different requirements in terms of our duty to have regard to the various conservation objectives set out in Section 7, but concluded that we should not.

We have considered the impact of the installation on local wildlife sites within 2Km which are not designated as either European Sites or SSSIs. We are satisfied that no additional conditions are required.

(iii) Section 81 (National Air Quality Strategy)

We have had regard to the National Air Quality Strategy and consider that our decision complies with the Strategy, and that no additional or different conditions are appropriateDraft for this Permit. For

7.2.2 Human Rights Act 1998

We have considered potentPublicial interference with rights addressed by the European Convention on Human Rights in reaching our decision and consider that our decision is compatible with our duties under the Human Rights Act 1998. In particular, we have considered the right to life (Article 2), the right to a fair trial (ArticleConsultation 6), the right to respect for private and family life (Article 8) and the right to protection of property (Article 1, First Protocol). We do not believe that Convention rights are engaged in relation to this determination.

7.2.3 Countryside and Rights of Way Act 2000 (CROW 2000)

Section 85 of this Act imposes a duty on Agency to have regard to the purpose of conserving and enhancing the natural beauty of the area of outstanding natural beauty (AONB). There is no AONB which could be affected by the Installation.

7.2.4 Wildlife and Countryside Act 1981 Under section 28G of the Wildlife and Countryside Act 1981 the Agency has a duty to take reasonable steps to further the conservation and enhancement of the flora, fauna or geological or physiographical features by reason of which a site is of special scientific interest. Under section 28I the Agency has a duty to consult Natural England/Countryside Council for Wales in relation to any permit that is likely to damage SSSIs.

We assessed the Application and concluded that the Installation will not damage the special features of any SSSI.

Newhurst ERF Page 80 of 150 EPR/TP3036KP

The CROW assessment is summarised in greater detail in section 5.4.2 of this document.

7.2.5 Natural Environment and Rural Communities Act 2006

Section 40 of this Act requires us to have regard, so far as is consistent with the proper exercise of our functions, to the purpose of conserving biodiversity. We have done so and consider that no different or additional conditions in the Permit are required.

7.3 National secondary legislation

7.3.1 The Conservation of Natural Habitats and Species Regulations 2010

We have assessed the Application in accordance with guidance agreed jointly with Natural England and concluded that there will be no likely significant effect on any European Site. Draft For The habitat assessment is summarised in greater detail in section 5.4.1 of this document.

7.3.2 Water Framework DirPublicective Regulations 2003

Consideration has been given to whether any additional requirements should be imposed in terms of the Agency’s duty under regulation 3 to secure the requirements ofConsultation the Water Framework Directive through (inter alia) EP permits, but it is felt that existing conditions are sufficient in this regard and no other appropriate requirements have been identified.

7.3.3 The Persistent Organic Pollutants Regulations 2007

We have explained our approach to these Regulations, which give effect to the Stockholm Convention on POPs and the EU’s POPs Regulation, above.

7.5 Other relevant legal requirements

7.5.1 Duty to Involve

S23 of the Local Democracy, Economic Development and Construction Act 2009 require us where we consider it appropriate to take such steps as we consider appropriate to secure the involvement of interested persons in the exercise of our functions by providing hem with information, consulting them or involving them in any other way. S24 requires us to have regard to any Secretary of State guidance as to how we should do that.

The way in which the Agency has consulted with the public and other interested parties is set out in section 2 of this document. The way in which we have taken account of the representations we have received is set out in

From the information contained within the Application, it is my view that this site should not lead to a significant worsening of air quality. While it is not possible to rule out adverse health effects from modern, well regulated municipal waste incinerators with complete certainty, any potential damage to the health of those living close- by is likely to be very small, if detectable.

2) Consultation Responses from Members of the Public and Community Organisations

The consultation responses received were wide ranging and a number of the issues raised were outside the Environment Agency’s remit in reaching its permitting decisions. Specifically questions were raised which fall within the jurisdiction of the planning system, both on the development of planning policy and the grant of planning permission.

Guidance on the interaction between planning and pollution control is given in PPS23. It says that the planning and pollution control systems are separate but complementary. We are only able to take into account those issues, which fall within the scope of the Environmental Permitting Regulations. The way in which we have done that is set out in section 3 below. a) Representations from Local MP, MEP, Councillors and Parish / Town Councils Draft For Representations were received from Emma McClarkin (MEP), who raised the following issues.

Having considered the information submitted in the Application, we are satisfied that appropriate measures will be in place to ensure that energy is used efficiently within the Installation.

As well as maximising the primary use of heat to generate electricity, waste heat should be recovered as far as practicable, i.e. by identifying and utilising opportunities for Combined Heat and Power (CHP) and district heating.

The location of the Installation largely determines whether waste heat can be utilised, and this is a matter for the planning authority. The Applicant carried out a feasibility study (Heat Plan), which showed there was potential to provide district heating to local businesses; and opportunities are being explored.

An assessment of the impact of abnormal operations has been made in section 5.5 of this document. No abnormal emissions have been assessed as having the potential for giving rise to significant pollution

Potential emissions due to accidents have also been addressed in the Application. We are satisfied that appropriate measures will be in place to ensure that accidents that may cause pollution are prevented but that, if they should occur, their consequences are minimised.

The process contribution for NO2 for long term emissions is predicted to be 1.1% which only just over the 1% threshold of insignificance, and is actually just 1.4% of the current background levels of NO2 in the area.

Given that the emissions will not cause significant pollution, it is considered that they will not cause any significant increase in erosion of the listed buildings

With specific reference to the quarry void and surrounding woodland, peregrine falcon has been recorded repeatedly in this area and it is considered that this species is nesting in the quarry void ledges or surrounding woodland “

The impact on air quality is discussed in detail in section 5.2 of this document.

The impacts of noise are discussed in Draft Fsectionor 6.5.5 of this document. The Applications ecological assessment of noise impacts concludes that “The operation of the ERF at the Application site Publihasc been assessed to produce noise levels which are below that of the current level of background noise at the site. Although the ERF would operate for 24 hours a day and Consultathereforetion produce noise during the hours of darkness, the level of noise created is considered unlikely to impact upon any features of ecological value within and around the site. As such, no impact as a result of the noise created by the ERF is predicted. “

We consider that the facility will not have any significant impact on air quality or noise, or on Falcons or Rooks.

The noise assessment does not assess the quarry face as a location of a sensitive receptor, and so for completeness pre- operating condition PO4 requires the assessment of noise impacts on potential nesting sites within the quarry.

3) Matters which are outside the Agency’s Permitting Remit

Location of the installation: Decisions over land use are matters for the planning system. The location of the installation is a relevant consideration for Environmental Permitting, but only in so far as its potential to have an adverse environmental impact on communities or sensitive environmental receptors. The environmental impact is assessed as part of the determination process and has been reported upon in the main body of this document. The location of the installation can have an impact on the ability to recover waste heat for use in nearby residential, commercial or industrial premises and we comment on this in our consultation response to the local planning authority.

Vehicle access to the installation and traffic movements: These are relevant considerations for the grant of planning permission, but do not form part of the Environmental Permit decision making process.

Flood Risk: The Environment Agency provides advice and guidance to the local planning authorityDraft on flood risk in our For consultation response to the local planning authority. Our advice on these matters is normally accepted by both Applicant and Planning Authority. When making permitting decisions, flood risk is still a relevant consideration, but only in so far as it is taken into account in the accident managementPublic plan and that appropriate measures are in place to prevent pollution in the event of a credible flooding incident.

The Use of Alternate Technologies: It is argued that Incineration is not an environmentallyConsultation sustainable technology and therefore almost by definition cannot be considered to be the Best Available Technique (BAT). The Environment Agency is aware that a number of proposals are coming forward for other ways of dealing with waste streams such as pyrolysis and mechanical / biological treatment. At this time however, mass burn incineration at this scale can still be considered BAT, subject to the appropriate assessments being made. Anaerobic digestion is most suitable for high moisture content biodegradable wastes such as food and agricultural wastes, and can be applied where there is separate collection of these waste streams. Anaerobic digestion is not however appropriate for mixed municipal waste. Some technologies such as plasma arc gasification are currently considered not to meet the definition of ‘availability’ due to their very limited Application worldwide.

It is important to draw a distinction between Sustainability Appraisal and Best Practicable Environmental Option (BPEO) and BAT. In Planning Policy Statement 10 (PPS10) (Planning for Sustainable Waste Management) Sustainability Appraisal forms part of the decision making process which should be applied so as to shape planning strategies that support the Government’s planning objectives for waste management. Thus Sustainability Appraisal is an important part of plan formation and planning decisions are made by reference to planning policies. BPEO forms a similar function in Wales. BAT assessment is a technical appraisal that the proposed

Newhurst ERF Page 149 of 150 EPR/TP3036KP

technique is the best available for the protection of the environment as a whole.

Incinerator Capacity and its effect on Waste Recovery and Recycling Activities: It is argued that as the quantity of residual waste reduces over the lifetime of the installation, the need to maximise efficiency by maintaining the incinerator at full capacity will suppress waste recovery and recycling initiatives, which are higher up the waste hierarchy. Any material arriving at the facility will be residual waste arisings following upstream waste segregation, recovery and recycling initiatives. The Environment Agency’s role is to ensure that it can be operated without giving rise to significant pollution or harm to human health. In any event Permit conditions will prohibit the burning of any separately collected or recovered waste streams.

Import of Waste: It is argued that diminishing supplies of residual waste from the surrounding area over the lifetime of the installation will result in the importation of waste from outside the area or sub-region. This is similar to the point above on the potential impact on local recycling. Draft For
