The contract will require operation & maintenance of sites In addition to plant there is a mixture of buildings and infrastructure, storage facilities and satellite offices to be managed. The sites are operational 24hrs a day, there is the requirement for stand-by support over evenings & weekends, including response times. In excess of 30 new schemes are expected to be designed and built by the Coal Authority over the contract period, the design and build is excluded from the contract but expertise from the contractor may be sought to support and review the design for suitability from an operational viewpoint. In a typical year the facilities treat over 128 billion litres of mine water and to ensure water quality is compliant with consents they consume over 150t of hydrated lime and over 50t of Limesol liquid lime, 3t of polymer, over 1000t of Sodium Hydroxide (47% mainly with some 20% concentration) and over 250t of Hydrogen Peroxide.

1. Background The Coal Authority (CA) requires a mine water pumping borehole to assess rising mine water on the surrounding environment at Westleigh, Wigan. A review of the mine water block has highlighted that mine water levels in the area could be elevated in respect to the rest of the block. There is potential for elevated mine water levels which could pose a risk to the overlying drinking water aquifers and the surface water environment. Therefore, the CA requires construction of a borehole to intersect flooded underground workings and will be used to improve understanding of mine water in the Golborne-Bickershaw-Parsonage mine water sub-block of the Lancashire Coalfield, through water level monitoring, quality sampling and long-term abstraction. 2. Key Requirements The Contractor will be responsible for specific construction details to achieve the borehole requirements, as specified below. Summary of key requirements Parameter Requirement Operational time: By March 2025. Methodology: Anticipated to require a pilot hole to be drilled by wireline coring methods to assist in maintaining verticality. Borehole depth: Estimated 200 - 250 metres below ground level (m bgl) Final internal diameter: Minimum of 400mm. Borehole deviation: <2m from surface location of borehole (<0.6° from vertical). Design life: Minimum of 20 years. Headworks: To be completed under a square split lockable manhole cover at surface, minimum of 600mm x 600mm with D400 rating. 3. Engagement Opportunities The CA are always looking for ways to improve and streamline projects. Due to the defined verticality requirements, it is envisaged that the most robust and reliable method of completing the mine water monitoring boreholes is by drilling a pilot hole using a wireline coring system, followed by reaming to the required diameter(s). The CA would welcome your feedback on this.

Purpose The Coal Authority (CA) operate 166 individual reed beds providing treatment capacity at over 62 mine water treatment sites. The purpose of the mine water treatment sites is to remove iron that has been mobilised from old mine workings into groundwater. These mine water treatment sites operate by enabling oxidation of the iron, which is then precipitated as iron hydroxide (ochre) and settled in settlement ponds. The effluent from the settlement ponds is then passed through reed beds to polish the water before discharge to local water courses under discharge consents. The reed beds are planted with a variety of wetland plants that act primarily as filters to remove any remaining ochre from the water before it is discharged. Over time there is a build-up of ochre within the settlement ponds and biomass from reed growth together with the ochre and any wind-blown dust that is captured within the reed bed. For the reed beds and settlement ponds to operate correctly the available headroom for the water levels have to be maintained within an acceptable range. So an amount of this build up has to be removed periodically and disposed of through an environmentally sustainable route. Detail To achieve the removal of the build-up within the reed beds and settlement ponds, we require a competent and experienced contractor(s) to provide an environmentally sustainable disposable route for the reed bed and settlement ponds material. There are three specific areas the Coal Authority are looking at. i) Reed bed material disposal. ii) Dried ochre disposal. iii) Dried ochre bagging and storage management. The contractor(s) will need to demonstrate their ability to dispose of the material complying with the permits required for disposal and their expertise in finding environmentally friendly disposal routes i.e. not landfill Permit required: Bespoke mobile plant permit for land spreading using EWC 19 13 06 Factors to consider if looking to obtain permit • Current workload and availability of the EA. • The information provided by the contractor. • Relationship the contractor has with the EA. • Availability of technical information required for the permit application. At this stage we are engaging with the market to ascertain interest and insight for the following scenarios. 1. We have the permits and are interested in bidding 2. We do not have the permits but are willing to obtain the permit(s) and bid Please register your response & interest to AdamBeckett@coal.gov.uk Estimated value of the contract i) Reed bed material disposal : £8.92m ii) Ochre bagging, management and transfer: £320k Estimated length of contract: 4 years Location The Coal Authority operates sites within Scotland, England and Wales in a wide variety of settings across former collieries in and around urban areas across the mining regions of the UK.

In partnership with the Department for Energy Security and Net Zero (DESNZ), the Department for Environment, Food and Rural Affairs (DEFRA), the Environment Agency (EA), Scottish Environment Protection Agency (SEPA) and Natural Resources Wales (NRW), the Coal Authority delivers a program of Water Treatment facilities covering 70+ mine water treatment schemes across England, Scotland and Wales, ensuring that any accumulated mine water is responsibly treated before entering natural watercourses. The Coal Authority's schemes and solutions to the treatment of mine water prevents uncontrolled discharges of mine water and controls mine water levels within the underlying mine water blocks. Construction of treatment facilities are critical in preserving our natural environment from the after effects of mining, mitigating the risk of ocherous deposits smothering river beds, which impacts the ecosystem and cause's significant localised harm. The Coal Authority are seeking to appoint a number of Contractors to deliver design and construct and construct only services for new mine water treatment schemes and also to refurbish existing schemes along with associated minor works. The treatment of metal mine water will also fall within this scope to mitigate pollution caused by historical metal mining. Typical construction activities conducted within this framework may comprise of; - A brand new or major refurbishment of a minewater treatment scheme - Refurbishment and upgrade of existing minewater treatment schemes A further breakdown of the types of construction activities can be found on the attachment contained in this notice. The proposal for the procurement is a framework for a total duration of 4 years. The Coal Authority are committed to becoming a more sustainable organisation (environmental and social) & want to use our work to help deliver positive change in the communities we support.

The Coal Authority requires specialist technical support to build a predictive hydrogeological and geochemical model to assess the potential impacts of saline rising mine water on surface water and groundwater receptors in the East Midlands. The study area comprises an extensive and complex series of coal workings which are partially flooded and rising. Part of the mine system is currently being pumped and monitored as part of an ongoing hydrogeological test pumping exercise. Specialist modellers and hydrogeological consultants are invited to attend an initial 1 hour meeting with the Coal Authority to discuss possible modelling approaches and what their organisation can offer. An individual meeting will be held with each interested party via Teams with the chance to follow up with an information pack based on the discussions.
