AYESA / Waste Management / Waste Facility Permitting & Licensing

Waste facility Permitting & Licensing Our understanding of the waste facility permitting and licensing process end-to-end provides a holistic service.

We bridge the gap across all stakeholders, the client, contractors, planning and regulatory authorities and public consultation, where needed.

Helping waste clients meet obligations European and national environmental legislation impose stringent legislative controls over a wide range of industrial and commercial activities. The legislation requires operators of ‘regulated facilities’ to obtain the appropriate permit to operate or discharge substances to air, water or land. The aim of the legislative regime is to protect the environment and to promote best practice in the operation of the regulated facilities.

Assisting Planning and Construction through permitting and licensing Our teams have many years of experience in supporting planning applications, obtaining environmental permits, and supporting the construction of regulated facilities in the most cost-effective way. We work with operators to provide permit compliance by environmental monitoring and reporting services. In addition, our analyses supports validation operational issues by ensuring compliance with waste acceptance procedures and practices.

Client Due Diligence We prepare permit variations to comply with changing legislational operational practices and to facilitate change of operator through permit transfers. Our environmental monitoring data can also feed into risk assessment and management strategies to ensure compliance with the permit licence. These monitoring services can form the basis of the eventual permit surrender application.

Assessments to support Permit Processes To support permit processes we provide environmental risk assessments; landfill gas risk assessments; hydrogeological risk assessments; stability risk assessments; fire prevention plans; odour and pest risk assessments and management plans; and environmental management systems.

Experienced with Hazardous and Non-Hazardous Facilities We have worked across all developmental phases on behalf of a broad range of facilities, including hazardous, non-hazardous and inert landfill sites, Material Recycling Facilities (MRF), Mechanical Biological Treatment (MBT) facilities, In-Vessel Compositing (IVC) facilities, Authorised Treatment Facilities (ATF) for end-of-life vehicles, and bespoke facilities e.g. ship and oil rig decommissioning. In addition, our permitting experience extends to a wider range of industrial processes, including non-ferrous metal melting, wood treatment, wood combustion and mineral extraction and processing.

Site Selection, Permit, Design of Solid Waste Disposal and Modern Waste Facilities We help clients in many ways, consulting on site selection, permit application, or design new solid waste disposal facilities or upgrade existing facilities, ensuring optimum solutions for capacity, staging and community acceptance. Our team have advised on planning, permitting and construction of modern waste facilities. Our aim is to progress projects on time, on budget and costeffectively. We consider the impacts of alternative technologies in integrated waste management systems.

When you work with Ayesa, you can be assured our experts understand the latest technical issues, regulatory drivers and the commercial pressures of the waste industry.

PROJECT FOCUS: A ‘FIRST CLASS’ APPROACH TO EXPANDING ONE OF THE BUSIEST AIRPORTS IN THE WORLD HEATHROW AIRPORT EXPANSION OUR ROLE Our team was appointed to provide environmental assessment, permitting support for the project as well as landfill remediation and design. The Heathrow Expansion Programme is a £14bn project to construct a third runway and new taxiways linking it to the rest of the airport complex, a new terminal building and satellite, additional stand areas, newairport gateways, carparks and other associated infrastructure. It will involve re-routing the M25, diversion of rivers and substantial earthworks to achieve.

SOLUTION We provided advice on the remediation of three existing permitted landfill sites located along the line of the proposed new runway and to design and support the permit applications for four new landfills. The new runway is to be constructed on top of three pre-existing landfills posing complex remediation and foundational design issues. The existing leachate and landfill gas control systems needed to be replaced and a new capping system installed.

The four new landflls are being designed to EU/ UK standards and need to take account of their close proximity to a working airfield with associated access restrictions. Our Waste team were subcontracted to Jacobs who were appointed as lead earthworks consultant for the project.

Our role in this project was multi-disciplinary with our consultants providing a full range of services; earthworks design, site investigation support, hydrogeological risk assessments, stability risk assessments, air quality assessment, design of landfill gas, leachate and odour control systems, environmental monitoring, regulatory compliance and advice on landfill tax.

PROJECT FOCUS: WASTE RECOVERY ACTIVITY IN A HIGHLY SENSITIVE HABITAT

BROCKHOLES QUARRY, PRESTON OVERVIEW The site operator Hargreaves North West appointed Ayesa to help secure planning and permit applications to restore their 24-hectare quarry in Lancashire. Previously, the quarry had been used for the extraction of sand and gravel for the construction industry. The site is located in a sensitive groundwater and surface water regime.

The restoration scheme will need some 246,000 cubic metres of suitable restoration materials. to be imported and placed. The recovered area will be developed into a wet grassland habitat with emergent species margins. The site will also house lakeside fishing lodges with access tracks and parking.

INNOVATION / VALUE ADD Getting the project off on the right foot is key and bridging the gap across stakeholders is where our teams excel. At the start of the project, we held discussions with the client, local planning authorities and environmental regulators to determine the scope of the application. Our team designed and installed the monitoring boreholes, essential to complete the flood risk and hydrogeological assessments. These asessments also feed into the surface water management plan. When the Planning Permission and S106 agreement were secured our team devised the Waste Recovery Plan (which included the following assessments: environmental site setting and design, environmental risk assessment, hydrogeological and hydrological risk assessment and the environmental management system) This application was successfully approved by the Environmental Agency.

As operations continue, Ayesa will continue to monitor ground gas, groundwater and surface water to assess any impacts on the sensitive surrounds, water and ecosystems. This monitoring is also important as it forms the basis for the future site closure and permit surrender. In addition, on behalf of the client, we will assess waste to confirm its suitability as site restoration material.

Our role will continue through the restoration and closure phases as we provide informed expertise to our client to help expediate works towards completion and provide authorities with the rquired information for compliance throughout the entire project lifecycle.

PROJECT FOCUS: SUCCESSFUL AQUISITION OF PERMIT VARIATION FOR EDWIN RICHARDS QUARRY EDWIN RICHARDS QUARRY RESTORATION & INFILL OVERVIEW Edwin Richards Quarry was a former hard rock quarry over 80 metres deep located in an urbanised area west of Birmingham in the Midlands, UK. It had been partially infilled with municipal wastes but then mothballed after waste inputs reduced as a result of increased recycling and rising landfill taxes. Over 5 million cubic metres of void remained at the site and the unrestored quarry posed an ongoing stability and safety hazard.

The multinational utilities company which operates the site is one of the largest waste management companies in the UK. The Ayesa team were able to advise them on how to re-permit the site to complete its restoration using a specific range of non-hazardous wastes, make use of the remaining airspace asset and realise the development potential of the wider site PRIMARY ROLE Ayesa worked closely with the client’s estates team to develop a forward master plan for the whole site, support their planning application and prepare the permit variation application to the Environment Agency. We were successful in obtaining the permit variation which provided for a highly efficient methodology of infilling the site, both in construction cost and landfill tax-saving terms.

Location: Birmingham, UK Capital Value: Undisclosed Project Name: Edwin Richards Quarry Restoration & Infill Country: UK Client: Waste Recycling UK

INNOVATION / VALUE ADD The permit variation application was complex involving the preparation of quantitative groundwater and geotechnical risk assessments and innovative waste acceptance protocols.

Subsequently, a separate permit was secured for a hazardous soil wastes treatment facility on the site. Ayesa has also installed new environmental monitoring boreholes and provides ongoing regulatory compliance advice.

AYESA / Waste Management / Waste Facility Design

Waste Facility Design A Leader in Waste Facility Design Activities carried out at waste facilities include disposal, treatment, recycling and energy generation. They are a crucial part of ensuring we sustainably manage the wastes produced by households, commerce and industry. These facilities are varied and include mechanical, thermal, chemical and biological treatment of wastes, soil remediation plants and landfill disposal.

Materials that cannot be recovered or recycled, including the residues from treatment facilities, are disposed of in a landfill. Ayesa has extensive experience providing complete design services for waste facilities or providing specialist inputs to larger development consortiums.

Our team of multidisciplinary experts has delivered the design and master planning of nationally significant waste management projects in the UK and MENA region, including the 18 million cubic metre capacity, triple landfill Sohar Industrial Waste Handling and Treatment Facility (IWHTF) in Oman and at multiple, extensive scale waste management facilities over 20 years for the two leading waste management operators in the UK. We can also design the remediation works at former waste management facilities, including treatment plants where soil and water contamination has occurred and historical landfill sites.

PROJECT FOCUS: 20 YEARS OF PROJECT MANAGEMENT, DESIGN AND SUPERVISION AT JAMESON ROAD LANDFILL JAMESON ROAD LANDFILL OVERVIEW The Jameson Road facility is a major regional landfill in Lancashire, UK accepting a range of MSW, Industrial and Commercial wastes. It was formerly a local council operated site, now owned and operated by multinational utility company SUEZ. For the past 20 years the Ayesa UK team have provided comprehensive multidisciplinary construction support, master planning, design and permitting advice on this site to SUEZ. The site initially required extensive remedial works to bring it up to modern standards, including the design and installation of over 40 hectares of capping and isolating the older part of the site with a major engineered separation bund. Over 20 years the remaining area of the site was progressively developed with new engineered containment cells, constructed to the standards required by the EU Landfill and Groundwater Directives. Extensive landfill gas and leachate management systems have been installed.

PRIMARY ROLE

Location: Fleetwood, UK Capital Value: >£25m Project Name: Jameson Road Landfill Country: UK Client: SITA Suez UK

We initially project managed the remediation of the former council operated part of the site, designing and supervising an 800,000 m3 translocation of wastes, construction of a 1 km long engineered separation bund and installation of 40 hectares of geosynthetic capping.

For over two decades Ayesa have periodically designed, supervised and verified the construction of multiple new landfill cells and associate capping works as landfilling has progressed across the remaining 60 hectares of the site. The landfill is lined with a composite mineral clay / HPDE liner and capped with an LLDPE geomembrane.

For each new, separate cell construction and post infill capping contract we have assisted the operator to procure the contract and supervised the works. This starts with the detailed design, securing approval from the regulator (UK Environment Agency), preparing the contract specification and issuing the tender pack to contactors. We then supported our client through the tender evaluation process, contractor appointment, management of the contract works and by providing site-based supervision of the works. On completion of the works, we provided the regulator with the necessary CQA verification reports.

PROJECT FOCUS: EXTENSIVE REMEDIATION WORKS TO 45-METRE-DEEP HARD ROCK QUARRY WHINNEY HILL LANDFILL OVERVIEW The site is a 45-metre-deep hard rock quarry with over 15 million m³ of void space. Ayesa designed and project-managed extensive remediation works to the older, former local authority landfill for Municipal Solid Waste (MSW), industrial and hazardous wastes. Ayesa also designed four new landfill cells.

Remediation works included the excavation and translocation of 300,000m³ of waste and construction of a 40m high engineered separation bund. A risk-based design approach was undertaken in accordance with PPC/EPR regulations and Environment Agency guidance. This included quantitative hydrogeological, landfill gas and stability risk assessments.

PRIMARY ROLE Ayesa have provided the lead engineering design role on this site for over 20 years covering both the Phase 1 remediation works and the Phase 2 development of multiple new engineered containment cells. We have also provided extensive construction contract support, site supervision and CQA validation of the earthworks and containment liner installation works. In 2019 Suez commissioned Ayesa to design the leachate treatment system upgrade, commencing with a process design commission.

In support of the design works we have undertaken extensive hydrogeological and geotechnical investigations, Environmental Impact / Risk Assessments, input to planning applications and provided extensive Environmental Permitting support.

PROJECT FOCUS: MAJOR CLEAN-UP OF OIL CONTAMINATED SOILS KUWAIT CONTAMINATED SOIL REPOSITORY OVERVIEW This project was part of the major clean-up of oil contaminated soils which were a legacy of the 1991 Iraq war. When retreating from Kuwait, the Iraqi army destroyed hundreds of oil wells contaminating over 25 million m3 of soil. Under the auspices of the United Nations, a clean-up programme was initiated which involved a mix of bioremediation, thermal treatment and landfilling.

Ayesa was the lead design engineers for the construction of a 1 million tonne landfill repository, located in the oilfields to the south of Kuwait City.

The contract was let by the Kuwait Oil Company under the Kuwait Environmental Remediation Programme (KERPS) scheme, as a design and build project.

PRIMARY ROLE Ayesa provided tender support to our D&B client which was successful in the face of stiff international competition.

Our role included a site selection study, design and supervision of borehole investigations, environmental monitoring, hydrogeological studies, geotechnical studies, earthworks and landfill engineering design, leachate management design, surface water design, construction supervision and CQA, and preparation of the operational, monitoring and post closure plans.

The work was undertaken in two phases, the first to construct the base of the repository and then following infilling, to cap and restore the site.
