Non-Technical Description

This application is being made to vary permit EPR/HP3095CT/V005 for the Anaerobic Digestion and Combined Heat and Power facility at Netheridge Sewage Treatment Plant operated by Severn Trent Ltd. The proposed changes are:

• to increase the total permitted waste throughput by 50,000 tonnes per annum by accepting hazardous waste from third party commercial sources in addition to the currently permitted non-hazardous wastes imported to site; and

• to amend the Schedule 1 permitted Activities on site to reflect the new activities of mixing / blending hazardous waste prior to biological treatment and then the biological treatment of the hazardous waste;

The site currently treats both indigenous sludge from the waste water treatment works on site and imported non-hazardous waste. The imported waste includes sludge from smaller sewage works which do not have their own anaerobic digestion plant on site as well as domestic sludges from properties not connected to the sewer system, and liquid / sludge trade waste. The indigenous sludge and imported domestic sludge currently fall under the scope of the Urban Wastewater Treatment Directive (UWWTD) and is controlled by separate regulations, so the quantities and waste types permitted by this permit only include the other imported wastes.

Indigenous sludge is removed from the aerobic digestion process and pumped to a dedicated holding tank. Imported wastes in liquid or sludge form are delivered to the site by tanker. After testing and approval, imported wastes are initially transferred to one of two import tanks which can accept both hazardous or non-hazardous wastes. One tank is for low strength wastes and the other high strength. Strength refers to the ammonia and chemical oxygen demand (COD) within the waste stream and influences how the waste streams are blended in the blending tank prior to transfer to the digesters.

The imported liquid/ sludge wastes are discharged into the holding/ mixing tank for mixing with the indigenous sludge before being transferred to one of the four primary digesters for treatment. Biogas produced is used on the site in two combined heat and power engines and in two auxiliary dual fuel boilers. Electricity generated at the site is used both within the site and exported to the national grid, depending upon the current electricity spot price and on-site operational requirements.

It is proposed to increase the throughput on the site by accepting new additional waste types, including hazardous wastes which will be blended with the non-hazardous wastes before the mixed waste is treated in the anaerobic digesters. There are no planned changes to the infrastructure on site and the four digesters on site have sufficient capacity to treat the increased volume. The Installation operates controls to minimise emissions to air, water and land including; containment of potential odours and biogas, optimisation of biogas combustion, containment and treatment of materials and wastes. A planned maintenance and inspection programme is in place to optimise the operation of plant. The site accepts wastes for the following Recovery and Disposal (R & D) codes: R3 ‘Recycling / reclamation of organic substances which are not used as solvents (including composting and other biological transformation processes) and R13 (storage of waste) pending offsite R10.

Netheridge Anaerobic Digestion and Combined Heat and Power Plant

Section II – Summary of Proposed Changes

The Severn Trent Water Ltd, Netheridge Sewage Treatment Works site, is located at Netheridge Farm, Netheridge, on the southeastern edge of Gloucester. It currently takes in materials for treatment from three separate sources, which are subject to stringent chemical and biological testing prior to acceptance at the site:

• Sewage sludges are routine imports from smaller sewage works (with lower or no capacity for treating sludges on-site) which are imported into a larger works for additional treatment. This may be due to digester capacity or infrastructure issues.

• Liquids and other sludges are non-hazardous third party commercial wastes imported to the works for biological treatment.

• Domestic imports from properties not connected to the sewer system; this waste stream is outside of the scope of this permit due to being within the scope of the UWWTD.

It is proposed to accept third party hazardous commercial wastes and blend these with the non-hazardous wastes which the site is currently permitted to accept before treatment. The hazardous waste would be in addition to the current imported materials and it is proposed to increase the annual throughput of imported wastes by 50,000 tonnes per annum.

Description of Site Activities

Wastes in liquid or sludge form are delivered to the site by tanker. Waste pre-acceptance and acceptance procedures follow Severn Trent’s agreed tanker trade waste methodology. All waste deliveries are pre-booked in to the site and subject to pre-acceptance testing to confirm their suitability for treatment at the site. Upon arrival, waste transfer notes and the tanker clear wash certificate (if appropriate) are checked against the pre- acceptance information. A sample of waste is taken from the tanker sight glass and confirmatory testing carried out prior to offloading. Following checking, the tanker is allowed to be discharged. Where loads do not comply with these requirements, they are rejected. If they meet the site’s acceptance criteria, imported wastes are discharged into one of two import tanks. One import tank is for low strength wastes and the other import tank is for high strength wastes. Strength refers to the ammonia and chemical oxygen demand (COD) within the waste stream and influences how the waste streams are blended in the blending tank prior to the digesters.

Indigenous sewage sludge is removed from the aerobic process via gravity within the primary settlement tanks then pumped into a holding tank. Imported sludges are then transferred from the import tanks to the holding tank for mixing, and the mixed sludge is transferred to the anaerobic digesters. The holding / mixing tanks are equipped with an odour control unit (OCU).

Pre-mixed wastes are transferred via pipework to one of the four primary anaerobic digesters at the site, each with an operational capacity of circa 2,800 m3. The tanks are constructed of concrete with steel roofs. They have a conical base which extends below ground surface and the tanks are built up 20-30% around the base. The contents of the anaerobic digesters are mixed through use of sparging from the methane gas compressor, while the contents undergo anaerobic degradation. The anaerobic digestion process gives rise to biogas (largely methane), which rises through the digester for capture and transfer to the adjacent floating roof gas storage tank for utilisation on site. The biogas storage tank, which is constructed from metal and is fitted with a floating roof includes several environmental and safety process controls (including Whessoe type pressure release valves). The gas storage area is classified as a potentially explosive atmosphere, with strict provisions on the control of potential ignition sources.

Due to the generation of biogas, the digester is operated partly full, to give headspace for biogas generation. The top of the digester is fitted with Whessoe type emergency pressure relief valves to prevent excess pressure build up. The digesters are equipped with high level monitors to check levels and anti-foam added as required

11 Netheridge Anaerobic Digestion and Combined Heat and Power Plant

Section II – Summary of Proposed Changes

to the inputs to prevent foaming occurring. In order to operate within the correct temperature range for optimal digestion, each digester is equipped with a heat exchanger. Heat (hot water) is supplied to this system either through transfer of waste heat from the biogas engines on the site, or through use of the supplementary boilers at the site. The tanks are surrounded by sections of concrete hardstanding, with a mix of grass and gravel beyond.

The anaerobic digesters operate as a continuous process with sludge being added and treated sludge extracted. Sludge is retained within the anaerobic digester for approximately 12 days. Sludge extracted from the digesters is then transferred to the buffer tanks, before dewatering occurs by centrifuge.

Fully treated sludge is then transferred for dewatering. Here a polymer-based coagulant is added to the sludge to enable removal of supernatant liquor through centrifugation. The removed supernatant liquor is returned to the head of the works, for treatment through the aerobic treatment route. The produced sludge cake is transferred via conveyors to the adjacent sludge cake pad. The cake pad is engineered hardstanding with segregation provided for differently aged sludge, and drainage provision to capture run-off, which is also returned to the head of the works. Once on the cake pad, sludge cake is analysed to check if it can be landspread in accordance with the requirements of the Sludge (Use in Agriculture) Regulations 1989 (as amended). If the sludge cake is not suitable for application immediately, remedial actions are undertaken to prepare it for reuse. This may be through increased retention time on the pad, mixing with lime, or reprocessing, as required to achieve pathogen kill and other required properties.

The biogas produced in the digesters is wet, and transfer lines are equipped with drainage pots to capture excess water (condensate). These are drained to a sealed drainage system with the water returned to the head of the works. The drier biogas is thermally treated on site. Due to levels of siloxanes within the biogas, which can lead to operational issues for gas engines, the biogas is passed through a GAC filter system to remove siloxanes. The removed filtrate is returned to the head of the works for additional treatment. Hydrogen Sulphide (H2S) monitoring is provided, due to the potential for elevated levels to be present in the biogas. Ferrous dosing is available if needed, but levels of H2S present mean it is seldom used. The site has two Jenbacher 316 gas engines for the combustion of biogas and generation of electricity. These engines have a thermal input of 2.09MW per unit. Heat from the combustion process is used to regulate temperature in the anaerobic digesters, with any excess being discharged using air cooled radiators. Due to the limited levels of unused waste heat at the site, there is no potential for additional CHP outlets. Electricity generated at the site is used both within the site and exported to the national grid, depending upon the current electricity spot price and on-site operational requirements.

There are dual fuelled (oil / biogas) boilers on site which are used to regulate the anaerobic digester operational temperature, primarily when the CHPs are not operational. A flare is located at the site for treatment of biogas during periods of excess generation or engine / boiler downtime. Flare stack operation is automated based on gas level. If the gas level is high then the flare will operate, however utilisation of the gas is preferred over flaring.

Annex 2 - Review against BAT for waste treatmentincludes a review of the proposed site processes against the BAT conclusions given in Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council. The review concludes that the proposed processes are compliant with the latest BAT conclusions for the waste sector, as far as they apply to sites operating anaerobic digestion processes.

SCOPE

Severn Trent Water was awarded certification to BS EN ISO14001:2015 for its Environmental Management System in August 2018. The certified EMS scope covers “Management and delivery of wastewater treatment processes. Transfer and storage of highway waste on depots. CHP biogas plant activities. Mothballed landfill monitoring activities. Head office functions at Severn Trent Centre.” ENVIRONMENTAL POLICY

Implementation of the Severn Trent Water’s Environmental Policy is approved by the Severn Trent Executive Committee of the Severn Trent Plc Board and is the responsibility of all employees, with the Chief Executive being accountable for its implementation. The policy covers all Severn Trent activities, including this installation, and applies to all individuals who are employed by, or carry out work on behalf of, any Severn Trent group company including contractors, temporary staff and agency workers. The Management Systems Team (EMS specialists) is responsible for the implementation of the EMS, but the CHP team and the site operations teams will be responsible for maintaining ongoing compliance and managing the sites.

MANAGEMENT AND RESPONSIBILITIES

The Management Systems Team (EMS specialists) has overall responsibility for the management and upkeep of the EMS. Compliance with specific elements of environmental legislation is managed by the relevant Business Areas across the Company. The Management Systems Team (EMS specialists) maintain a Legal Register and, in consultation with Operations Teams, their permit compliance advisors and other specialists, assess environmental risks for in-scope areas using a significance scoring method under normal, abnormal and emergency conditions. Significant environmental aspects and impacts take into account legal and other requirements, cost to the business, scale of impact and interested parties.

Management Systems Team (EMS specialists) are responsible for setting internal environmental standards with Standard owners which are then implemented by the relevant business areas. The Standards and other relevant information are communicated through a number of routes. Incident and corrective action routes exist to promote continual improvement.

Local operating procedures are the responsibility of the operational teams that operate the sewage works. The defined roles and responsibilities are allocated to relevant personnel, depending on their job description, qualifications, knowledge, experience and training. Training and competency are based on specific roles.

OPERATIONAL CONTROL

Procedures are in place to identify and control environmental issues arising from Severn Trent Water activities. Each department is required to achieve operational control of its activities and, using a central database, identify and record any departmental environmental issues.

Routine sewage treatment operations and activities are recorded within the corporate management database, SAP. These include routine inspections, monitoring and maintenance tasks. The procedures and records of activities undertaken by the CHP team are held centrally at Minworth STW.

Non-routine activities, such as major overhauls / refurbishments, which involve the use of sub-contractors are assessed for health, safety and environmental risks and method statements are produced to address these.

Responsibility for signing off trade waste acceptability depends of the waste type. The trade waste manager is responsible for low risk waste such as food washing or alcohol, but high risk wastes need additional sign off from the site manager and trade panel chairman who covers a number of sites, for example for high strength COD wastes.

Maintenance of the anaerobic digestion plant, biogas, oil and water systems are the responsibility of the site manager and site staff. Most maintenance is undertaken by Severn Trent Water staff with some specialised work for boilers, pressure relief valves, flare stacks and leakage alarms handled through a centralised servicing and repair contract. All activities are closely managed from site to ensure that all Severn Trent Water H&S and environmental policies are met.

Operational management of the CHP plants is carried out by the Generation Services Manager and their team. This team monitor and service all the CHP engines in use. When contractors are used to carry out major services, these activities are closely managed by the team to ensure that compliance with Severn Trent Water’s H&S and environmental policies is achieved. No contractors may work on site without having undergone a full site induction.

Processes on site operate continuously, 24-hours per day, 7-days per week, apart from maintenance periods. The plant is designed to operate unattended with process parameters being monitored continuously. Operating logs are stored electronically. MAINTENANCE AND MONITORING

17 Netheridge Anaerobic Digestion and Combined Heat and Power Plant

Section III - Supporting Information

Management will have the ultimate responsibility for the effective maintenance of plant throughout the company. The facility has named staff that are responsible for day-to-day maintenance operations and contractors are also used as required, for instance the CHP service provider staff will be responsible for the maintenance of the CHP engines. The following basic inspections and maintenance activities are carried out on site:

1) Daily operation of plant (24/7) involves visual inspection of operational assets;

2) Daily inspection of temporary pipe work installed;

3) Weekly visual inspections of the bulk oil storage tanks and the oil pipework (visual check on above ground pipework);

4) Weekly inspection of all bunds (oil, transformer, temporary, etc.) and condition of containerised engines;

5) Routine maintenance programme for plant;

6) Routine lubrication programme;

7) Visual inspection/internal inspection of digesters as per digester cleaning programme.

Personnel responsible for the inspection, testing and maintenance of pollution prevention infrastructure are trained to an appropriate level to ensure compliance with the Infrastructure Monitoring Programme.

All regular maintenance of CHP engines will be completed on the time scale specified by the equipment manufacturer including routine inspections (e.g. weekly ignition testing will show when spark plugs have reached the end of their service life). A full engine overhaul is likely to be scheduled every 20,000 operating hours. This high level preventative maintenance is designed to avoid unscheduled down time, maximising the plant availability and its ability to control emissions and maintain an efficient level of operation between overhaul services.

Severn Trent Water is committed to environmental improvements and has established environmental targets and plans relating to materials and waste management, transport, climate change mitigation and adaptation (energy efficiency and renewable energy generation), water resources, biodiversity, river water quality, and drainage asset performance.

The EMS is subject to a Senior Management Review twice a year to consider environmental performance, objectives and targets and continual improvement. COMPETENCE, TRAINING AND TRAINING RECORDS

Severn Trent Water aims to ensure that all employees are in possession of the knowledge, skills and experience necessary to perform their role in accordance with the company's operating procedures and in full compliance with the law. Training needs are identified by the employee’s immediate supervisor or line manager.

The EMS delivers a structured environmental awareness programme and targeted awareness training, where a need is identified. Managers and the CMS (Competence Management System) Manager review the competence of those working for the company where the tasks have the potential to cause a significant negative environmental impact, or impact on the operation of permitted activities within the EMS scope. The EMS Team, Permit Compliance Technicians and relevant Departments are responsible for rolling out the Basic Environmental Awareness Modules and job specific training.

Section III - Supporting Information

For each internal training course held a Training Record is issued. The Training Record includes a statement of understanding, which the employee signs to confirm that he/she has attended the course and understood the subject matter.

Induction training is carried out by the responsible line manager and consists of an introduction to the Company's Environmental Health and Safety Policy and description of emergency response and spill prevention procedures.

Staff who work at the CHP facility, and with the new engines, will receive specific training in the plant’s operation and the environmental impact of the process as well as health and safety. The operators will have a detailed understanding of the operational procedures for the site for both normal and abnormal operation. As part of the training, operators will receive specific instructions relating to those aspects of plant operation that have the potential for a negative impact on the environment. This training will be provided by the equipment manufacturers or in-house staff as appropriate.

Severn Trent Water can demonstrate that permitted activities are managed by technically competent staff with its Competence Management System (CMS) that is independently certified to meet the requirements of an Industry Standard. All appointed Technically Competent Persons (TCPs) undergo EMS awareness training and CMS training. TCPs are required to re-take training every 2 years. A list of technically competent persons is stored within the CMS documentation on SharePoint. CONTRACTORS

There are several procedures to ensure contractors have the required skills and environmental competencies to carry out works at this installation.

Initially, contractors are assessed by the procurement department for inclusion on the approved supplier list, which includes health and safety and environmental criteria for example, waste documentation such as waste carrier’s licence/training certificates. Even when the contractors are on the approved supplier list, they are still further assessed for each specific contracted activity.

The contactor is required to submit a method statement prior to any commencement of work, identifying how work is to be undertaken and the associated risks. The method statement must be approved by the Site Manager, who will also identify any site hazards and issue an Authorisation to Work/Enter the site, following a site induction. When on-site, the contractor must carry this Authorisation to Work at all times. INCIDENTS, NON- COMPLIANCES AND COMPLAINTS

Severn Trent Water has procedures for incidents, non-compliances and environmental complaints.

Incidents are managed through site specific procedures which ensure that all incidents are logged and that necessary preventative and/or corrective actions are taken.

Complaints are managed by Customer Services, where all complaints are logged on the Complaints Records Online Storage System (CROSS). The Regional Managers are responsible for ensuring that action is taken and for liaising with the relevant regulatory bodies (where appropriate). They ensure that any complaint is investigated and, if found to be justified, that work is undertaken to resolve the issue. They also provide an appropriate response to the complainant in a timely manner detailing the reason behind the issue and the actions taken to resolve the matter.

Information regarding complaints is recorded to allow determination of an appropriate response (corrective action) and to determine what measures need to be taken in the future to prevent its reoccurrence (preventive action). These records will be maintained as part of the management system for a minimum of four years. COMMUNICATION

Section III - Supporting Information

There are regular meetings held on site to discuss all aspects of the treatment works and performance against targets. These meetings include the operation and performance of the installation. Other communication methods to promote environmental management issues and continual improvement include: ‘Lessons Learnt’ bulletins, OSC portal forums and compliance audits. AUDITING

The controls for addressing environmental aspects and impacts are checked through the EMS audit programme which is managed by the EMS Auditor. Findings are reported to Site Managers and their Leadership Team. The EMS also checks that other audit programmes exist for our wider environmental obligations, for example, CMS, MCerts and Operator Self Monitoring compliance assessments.

6 - Environmental risk assessment

An environmental risk assessment of the site changes has been carried out in line with the requirements of the Horizontal Guidance Note H1. This guidance specifies the following approach to carrying out an environmental risk assessment for a proposed activity:

◼ identify potential risks that your activity may present to the environment;

◼ screen out those that are insignificant and don’t need detailed assessment;

◼ assess potentially significant risks in more detail if needed;

◼ choose the right control measures, if needed; and

◼ report your assessment.

Classification of Overall Risk

Term Description Severe harm to a receptor may already be occurring OR a high likelihood that severe harm will arise to a Very high risk receptor, unless immediate remedial action works / mitigation measures are undertaken. Harm is likely to arise to a receptor, and is likely to be severe, unless appropriate remedial actions / mitigation High risk measures are undertaken. Remedial works may be required in the short term, but likely to be required over the long term. Possible that harm could arise to a receptor but low likelihood that such a harm would be severe. Harm is likely Moderate risk to be medium. Some remedial works may be required in the long term. Possible that harm could arise to a receptor, but where a combination of likelihood and consequence results in Moderate / low a risk that is above low but is not of sufficient concern to be classified as medium. It can be driven by cases risk where there is an acute risk which carries a severe consequence, but where the exposure is unlikely. Low risk Possible that harm could arise to a receptor.

Hazardous and non-hazardous waste recovery and disposal:

Note that Annex 2 - Review against BAT for waste treatmentincludes a review of the proposed site processes against the BAT conclusions given in Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council

1 - Are pre-acceptance procedures in place that are fully in line with the appropriate measures set out in section 2.1.1 of SGN 5.06, and which are used to assess a waste enquiry before it is accepted at the installation?

Standards are in place at the site which comply with the relevant parts of Section 2.1.1. Only wastes which have been determined as being suitable for treatment through the anaerobic digester are accepted at the site. No wastes are accepted for onwards transfer. Due to the restriction on treatment methods on site, there is no need to consider suitable treatment routing.

There are differing procedures for imports of third party commercial wastes and imports of both sludges from other waste water treatment plants and domestic imports.

For sludges originating at other waste water treatment plants and domestic import, these materials are a known waste stream and similar to the material entering the wider site under the UWWTD. As such these have limited pre- acceptance confirmatory analysis carried out on them prior to agreeing to their import.

Prior to acceptance of any third party commercial wastes, a written description of the waste and a representative sample are obtained. The representative sample is chemically tested for compatibility and subject to test processing a trial sized anaerobic digester. The laboratory sampling uses in-house analysis for the more common analytes and more detailed analysis if required from other laboratories. In some circumstances full laboratory analysis provided by the producer may be accepted. Only following confirmation that both the chemical parameters and the biological treatment testing are acceptable is the waste allowed on site. Sign off for acceptance of trade waste at the site depends upon the nature of the waste involved and its composition. Sign off will vary from the trade waste manager for low risk waste such as food washing or alcohol, to high risk wastes needing additional sign off from the site manager and trade panel chairman who covers a number of sites, for example for high strength COD wastes.

No chemical testing for waste oil is carried out, although a visual inspection is undertaken. No laboratory smalls are accepted at the site.

2 - Are waste acceptance procedures in place that are fully in line with the appropriate measures set out in section 2.1.2 of SGN 5.06, and which are used to cover issues such as loads arriving and being inspected, sampling waste, rejecting waste, and keeping records to track waste?

Standards are in place at the site which comply with the relevant parts of Section 2.1.2.

No containerised wastes are accepted at the site, only bulk tankered materials. Only wastes of the types and in Group A, Group B or Group C as listed in Tables 1b(i), 1b(ii) and 1b(iii) are accepted on site. Waste pre-acceptance and acceptance procedures follow Severn Trent’s agreed tanker trade waste methodology.

55 Netheridge Anaerobic Digestion and Combined Heat and Power Plant

Section III - Supporting Information

For all third party commercial wastes, on arrival tankers must report to the site manager or technically competent manager before unloading, and no unloading may occur prior to the consent of the appropriate manager. All tankers must provide evidence of wash out certificates or previous load declarations as appropriate to prevent contamination. The appropriate manager will check the loads accompanying waste transfer paperwork and will request a sample be taken. Due to a lack of sampling gantry, sampling occurs from the sight glass and must be witnessed by a member of site staff. No prior visual inspections are carried out of loads, due to the nature of the wastes being imported.

Paperwork with each load is then checked to confirm it matches the sampled material and that this is in agreement with the pre-acceptance testing on the material. Only following checking, are waste offloaded.

Sludge imports from other waste water plants are not subject to as stringent checking on arrival. However, these loads are subject to stringent checking at their point of origin. All loads are accompanied by appropriate paperwork and are required to check in with the site manager, site chemist or technically competent manager upon arrival on site.

All deliveries to the site are by tanker and discharged via a data logger to measure import volumes. This is logged in the site systems along with the origin of the waste, natures and producer. Where deliveries are of commercial wastes or untreated sludges, these are to reception tanks / mixing tanks, prior to transfer to the anaerobic digesters. Once wastes are accepted they cannot be easily separated, and their location onsite will be time dependent following their transfer to the digester.

Where a site accepts treated sludge imports from another sewage works for dewatering purposes, these are transferred to holding tanks prior to the dewatering plant. Sludge cake originating from the tank during the period of storage and treatment may be identified in the unlikely event of issues with cake quality.

3 - Are waste storage procedures and infrastructure in place that are fully in line with the appropriate measures set out in section 2.1.3 of SGN 5.06?

The scope of this application does not impact on waste storage procedures and they remain unchanged from the current permit.

4 - Provide a layout plan giving details of where the installation is based, the infrastructure in place (including areas and structures for separately storing types of waste which may be dangerous to store together) and capacity of waste storage areas and structures.

Only wastes tested as being suitable for treatment through the single process infrastructure at the site are accepted at the site, negating the requirement for keeping waste types separate. No changes to the site infrastructure are proposed the plant layout plan is as previously presented in V005 of the permit.

5 - Provide a summary of the treatment activities carried out on the installation. This should cover the general principles set out in section 2.1.4 of SGN 5.06 and the specific principles set out in sections 2.1.5 to 2.1.15 as appropriate of SGN 5.06.

See the technical description of plant processes presented as Section II of this application.

BAT for biological processes are set out in section 2.1.8 of SGN5.06. Site compliance with these requirements are set out within the responses to questions 1 and 2 of Appendix 5 of the application form above.

BAT guidance for sludge pressing is laid out in section 2.1.15 of SGN5.06. Site operations are fully in compliance with these requirements. Correctly treated sludge is not odorous and therefore does not need to be stored under cover. The final sludge cake pads are constructed of concrete with external walls to retain matter within them. Pads are engineered to fall to sealed site drainage, which returns any liquid or rainwater to the head of the works (via emission point T1). The pads are equipped with a wheel wash to prevent transfer of material and internal site roads are equipped with sleeping policemen to help remove any material not removed in the wash. All cake is retained on the pad for a minimum of 14 days to ensure complete pathogen kill has occurred, and subject to chemical checking prior to removal under the Sludge (Use in Agriculture) Regulations 1989 (as amended).

6 - Provide layout plans giving details of where each treatment plant is based, the main items at each plant, and process flow diagrams for the treatment plant.

6b - Provide a breakdown of any changes to the energy your activities use up and create The main site energy sources are electricity from the public supply, fuel oil and biogas generated by the anaerobic digesters which is combusted in the CHP engines to generate electricity and heat on site. Fuel oil is predominately used in back-up boilers. To maintain control of energy consumption, and improve it where possible, electricity and fuel consumption is reported and reviewed on a regular basis.

The proposed increase to the annual tonnage throughput is a very small part of the overall throughput of the site, most of which is not covered by this permit. It will also lead to a very small increase in the biogas generated which is used on site and in the excess electricity available to be exported to the national grid.

6c - Have you entered into, or will you enter into, a climate change levy agreement?

No, the activities are not eligible to take part in the CCL Scheme.

Describe the specific measures you use for improving your energy efficiency

The production and use of biogas to produce heat (which is used into the process) and electricity which is either used on site or exported to the National Grid, is the single greatest measure which allows the site to minimise its use of fossil fuels and maximise the use of energy, whilst recovering biological wastes.

6d - Explain and justify the raw and other materials, other substances and water that you will use

See response to question 3c above.

6e Describe how you avoid producing waste in line with Council Directive 2008/98/EC on waste Waste Minimisation The site is designed an operated as a waste recovery plant and as such minimises waste generation from its own operations. Other than sludge cake, generation of waste is generally minimal and, largely limited to packaging or scrap materials associated with engineering projects. Internal waste audits are undertaken from time to time to reduce raw material wastage as part efficient management of the process. In general, raw material and process material usage is monitored and reported against activity. Where practical, materials are transported to site and stored in bulk or containers are returned to the supplier. Waste Management The site has a number of areas where waste is stored. These areas are sited within the installation in order to optimise the collection and delivery of the waste materials from the site lies. The storage areas are regularly checked during housekeeping audits to ensure that waste management practices and procedures are adhered to. All non-conformities (such as leaking containers) are reported, investigated and corrected. The skips are clearly identified and located on hardstanding. Waste storage areas are located as far away from sensitive boundaries and watercourses as practicable. No waste is stored on site for a period in excess of twelve months. Severn Trent Water has a policy for the administration and management of specific waste streams including the control and management of data documentation. All transfer and consignment notes are kept as required by law. The site maintains a register detailing the routine waste streams and the responsibilities for ensuring that Duty of Care documentation is in place. Before any contractor is used, their carrier certification and waste management licenses (where required) are first checked and then recorded in the register. Only those contractors listed on the register are used. The following parameters are recorded; quantity, nature, origin and where relevant, destination, mode of transport and treatment method.

BAT BAT Scope Applicable Y / N? Implemented at site? Conclusion

Overall Environmental performance

1 EMS Y Y This requirement is broadly the same as the EA EMS requirement – while the BAT requirement features a few differences, the overall content of BAT1 is the same across all industrial sectors and processes and the current EA guidance is being used instead. Parts of the requirements are also covered by other BAT items

2 Waste control technologies / techniques Y – although the Y – covered by current site operating wording of this BAT methods This is a table of things you must do to control the environmental performance – it conclusion states it comprises 7 specific areas: Waste tracking is not applicable, as waste applies to all wastes, is subject to treatment or mixing on arrival, waste pre-acceptance; some requirements rather than being containerised. don’t fit with the type of waste acceptance; site involved waste tracking; output quality checking; waste segregation (applies to storage mainly); checking waste compatibility prior to mixing or treatment; sort incoming solid waste

3 Establish and maintain an inventory of waste water and waste gas streams, as part Y – partially, as there is Y – these are covered by operational of the EMS limited waste water or procedures at the site, along with SCADA waste gas produced and data monitoring the plant processes and waste water is generally outputs in real time. recirculated within the Waste gas is captured within the plant for plant beneficial reuse

Noise and vibrations

17 Noise and vibration management plan Y Y – as part of the EMS

18 Techniques for reducing noise and vibration Y Y – within existing EMS and as part of the site maintenance program

Emissions to water

19 Techniques for optimising water consumption, reducing waste water generation N Y - recirculation of process water reduces and reduced emissions clean water consumption at plant and minimises volume of waste water produced

20 Techniques for waste water treatment N / A – no waste water N / A released from site

Emissions from accidents and incidents

21 Accident management plan techniques: Y Y – these items are all covered by the site. Some aspects through the HAZOP design - Protection measures process for the site, and other through - Management of incidental / accidental emissions management system techniques - Incident / accident registration and assessment system

22 BAT is to substitute materials with waste for the treatment of other wastes Y Y – where possible the optimal mixture of feedstock is provided through blending of suitable waste streams with sludge for treatment

Energy efficiency
