UK Public Sector Contracts & Tenders

The Coal Authority invites you to tender for the Water and Abandoned Metal Mines (WAMM) programme in partnership with the Environment Agency and Defra, the Coal Authority are looking at ways of monitoring and reducing sediment from historic mining, which is rich in lead, cadmium and zinc, from polluting the water courses which is causing them to fail Environmental Quality Standards (EQS). Captured sediment is retained behind in river structures such as checkweirs, with the aim of reducing downstream river pollution. Monitoring of these checkweirs is required to ensure a level is maintained to allow them to work to the best of their capability. To continue the monitoring that has been carried out over the past three to four years we are looking to source a supplier to provide long term monitoring to collate data relating to the accumulation of metal rich sediment including chemical analysis of the sediment, volume and particle sizing and impact of any scour of river banks in accordance with the detailed requirements within the scope The initial works will focus on three established checkweirs but may be expanded with the construction of new structures elsewhere in England.

The Coal Authority (Client) was established by Parliament to undertake specific statutory duties, set out in the Coal Industry Act 1994, associated with licensing coal mining operations; managing property and the historic legacy arising from the ownership of the coal reserves and underground workings; settling subsidence damage claims not falling on coal mine operators and providing access to coal mining information. The Coal Authority has a legal duty under the Coal Mining Subsidence Act 1991, to repair properties damaged by coal mining subsidence in the five coalfield regions. The works are funded by grant in aid from central government, in order that the Coal Authority can discharge its statutory duty. The Coal Authority employs over 300, based mainly at the head office in Mansfield with some field staff remotely based in order to enable a fast response to incidents in the coal mining areas. The Coal Authority is funded by grant in aid from the Department of Energy Security and Net Zero (DESNZ). This notice is for the retendering of our metering contract which expires in September 2023 This notice is published by way of giving interested parties the opportunity to submit a tender in relation to this requirement. We require consolidated meter readings across approximately 80 sites, with additional sites to be included as they are commissioned at a rate or 1 to 2 a year. This is for consolidating smart meter readings from: • Electricity meters • Electricity generation meters • Electricity export meters • Water meters As part of this contract we will require maintenance of existing meters plus the installation of new electricity and water meters at approximately 10 sites around England, Scotland and Wales as well as a review and potential upgrade of electricity generation meters at approximately 10 sites. Meter readings should be provided on a central portal with potential to provide an API for data transfer to a Coal Authority reporting system in the future.

The Coal Authority invites you to tender for the provision of specialist technical support to scope, design, build and report the outputs from a predictive hydrogeological and geochemical model. The model is required to assess the potential impacts of poor quality rising mine water on surface water and groundwater receptors and to provide the technical basis for selecting the optimum mine water management strategy. The study area is in the English East Midlands and comprises a delineated area of abandoned coal workings which are partially flooded and rising. Specialist modellers and consultants are invited to tender for the work which will include the design, creation and running of the model as well as producing model outputs, risk assessments and technical reporting. All tender documents are available in our procurement portal InBye and instructions on how to access these documents and complete a submission are attached to this notice Additional information: All tender documents are freely available to interested parties on our procurement portal InBye - https://inbye.coal.gov.uk/s2c/ - please see the attached guidance document for details of how to access these documents and make your submission.

In 2011, the Water and Abandoned Metal Mines (WAMM) Programme was set up between the Environment Agency, Defra and the Coal Authority to address pollution of rivers by abandoned metal mines. Currently, the Coal Authority operates four WAMM mine water treatment schemes, each using a different treatment technology, which are improving water quality in about 20 km of rivers. In January 2023, Parliament adopted a statutory metal mines target, under the Environment Act 2021, to halve the length of English rivers polluted by harmful metals from abandoned metal mines by 2038. The Government's Environmental Improvement Plan (EIP), published in January 2023, estimated that to achieve this long-term target would likely require around 40 new mine water treatment schemes and a similar number of diffuse interventions. The EIP set a non-statutory interim target to construct 8 mine water treatment schemes and 20 diffuse interventions by 31 January 2028. To help deliver the interim and long-term targets, the WAMM Programme is currently investigating active treatment options for mine water discharging from abandoned metal mines by undertaking active treatment trials on up to five sites This opportunity is now open with a submission deadline of 29 October 2024 All interested parties are advised to visit each site to familiarise themselves with the sites layout, limitations, restrictions and access. Visits to the premises must be made by appointment only with the Coal Authority . There is limited parking at each site, interested parties shall only attend at the agreed time provided by the Client.

The Coal Authority is looking to award a number of packages of work through this tender ranging from 1 no. of the active trials up to 5 no. active trails. These may be at any of the 5 identified sites. The Coal Authority reserves the right to award to multiple parties depending on the proposals provided during the tender period.

The appointed party / parties shall design and supply a suitable pilot scale active treatment plant for each of the mine water sources to be treated. The appointed party / parties shall provide an individual report at the end of each trial detailing the outcomes.

The Coal Authority requires a service provider who can design, install and analyse data from Monitoring devices for use with Buildings or Landscapes which may be subject to Movement. We will also require the interpretation of this data in order to enable us to advise if movement is due to the impacts of historic mining or some other cause. On occasion these services will need to be deployed at pace in order to establish if there is a need for residential evacuation. We also require that appointed organisations act as an expert witness should any situations arise where our judgement is called to a tribunal. It is intended that Lot One will mainly be used our our Public Safety and Subsidence department for the monitoring and analysis of Structural damage caused by Historic Coal Mining. Other departments and permitted bodies may also make use of the Lot. It is intended that Lot Two will mainly be used our our Tips Response department for the monitoring and analysis of Landscape damage caused by Historic Coal Mine Tips. Other departments and permitted bodies may also make use of the Lot.
