The Coal Authority intends to tender for the provision of Hydrometric Monitoring services. The framework will be divided into approximately 7 lots: Lot 1 - Options Assessment Lot 2 - Weirs and Flumes Lot 3 - Loggers, Water Level Sensors, Rain Gauges and Water Quality Sensors Lot 4 - Velocity Meters Lot 5 - Spot Flow Gauging and Water Quality Sampling Lot 6 - MCERTS Lot 7 - Hydrometric Monitoring (General Lot)

The Coal Authority (TCA) currently manage their Health, Safety and Wellbeing (HSW) processes using a combination of systems such as MS Word and Excel. This makes it time consuming for both individuals and the team to administer. This can not only deter people from following the correct procedures, but it makes it difficult for the HSW team to identify and act on the information captured. It would be far more efficient and improve governance if key processes were contained within a single system, specially designed for this purpose.

The Coal Authority generates large volumes of environmental data through the part of our business which manages the environmental legacy of mining across the UK. We operate over 75 mine water treatment schemes that remove contaminating metals from mine water prior to the treated water being discharged into a receiving watercourse. Schemes range from complex process engineering plants, through pumped wet wells and boreholes / mineshafts, to totally natural (passive) schemes without a power source. The majority of treatment schemes comprise of aeration cascades, settlement ponds and reed beds. All schemes are subject to regulatory consents and licenses. We have an extensive monitoring network across the mine water treatment schemes monitoring scheme performance. A wider network of boreholes and sampling locations is used to monitor changes in ground water level (monitoring mine water recovery across coalfields) and water quality within mine workings and at untreated mine water discharges. The total number of monitoring locations is around 2,000 but this may rise to nearer 3,000 as new treatment schemes are built or treatment trials carried out. We are increasingly helping others with monitoring of other types of mines. Environmental data is collected across the treatment schemes and monitoring network which includes; laboratory analysis of water and solids, onsite water quality measurements, hydrometry data including manual and logged stage and flow readings from weirs and spot flow gauging, telemetered process data (such as pump rates or electric metering), manual and logged water level and temperature measurements from boreholes or mine shafts, logged rainfall data, manual or logged gas data and solid samples of lagoon sludge. Most data types are collected as continually expanding time series. A small part of the overall data comprises geophysical surveys of boreholes and shafts. The Coal Authority has a requirement for a single data storage system which will consolidate our environmental data sets, incorporate data processing, quality checking and editing tools (including recording of any automated, or manual data changes) and make the data more accessible for use across the business. We are inviting tenders for provision of an environmental data management system that will modernise the collection, quality checking, editing, storage, analysis and reporting of our environmental data.

The Coal Authority is an executive non-departmental public body, sponsored by the Department for Business, Energy & Industrial Strategy and our mission is to make a better future for people and the environment in mining areas. As a responsible and caring employer, we are committed to supporting the overall health and wellbeing of our employees. We have always provided annual medicals as part of this commitment but these were paused as a result of the COVID-19 pandemic. Previously we have provided a single one size fits all medical but recognise that people have become increasingly conscious of the benefits of monitoring their health and wellbeing and therefore may wish to have more comprehensive testing and assessment than what is provided as a standard. They may also wish for family members to have access to medicals. We are seeking a supplier that can provide high quality medicals that: • can easily be accessed across England, Scotland and Wales as our employees work across a wide geographical area within Great Britain • clear and simple reporting to enable our employees to proactively manage their health and wellbeing • offer flexibility to provide employees with the option of upgrading the medical and enabling family members to have a medical at the agreed rates by paying the additional cost directly to the supplier Additional information: Tender submissions must be made through our tendering portal - InBye.

Dan Y Graig Mine Manager for specialist adit works.

The Coal Authority is looking for a specialist contractor to undertake the refurbishment of existing sea outfall structure at Dawdon Mine Water Treatment Scheme, located approximately 1km south of Dawdon, County Durham. The works will be undertaken in accordance with the NEC4 Engineering and Construction Contract Option B Priced Contract with Bill of Quantities and further details can be found at www.neccontract.com. For further details and full description of the works, please see VI.3 Additional information of this notice for a more detailed description of the works. Here you will find the Scope and instructions on how to register for the event and gain access to the full tender documentation. Additional information: The Dawdon short sea outfall consists of two parallel 200mm pipes with a gravity flow approximately 350m to the discharge point 140m metres from the shore. The pipes were installed through directional drilling and emerge from under the sea bed at the discharge point. Each pipe comes to a T piece with duck bill diffuser elements fitted to each end of the T section. The base of the discharge arrangement was not sufficiently supported and this has allowed the pipework to rotate impacting discharge flows. This needs to be repaired and returned to the correct position with improvements to the support of the diffusers from a pre cast concrete base. The diffusers also had a protective structure that has been dislodged and this needs to be replaced by a new protective sleeve and cap. The protective sleeve can either be a pre-cast concrete pipe or an HDPE pipe section which will be capped by a pre-cast concrete or GRP lid. The replacement duckbills will have to be fitted after the sleeve is placed. Alternatively, arch shaped cut-outs could be implemented, to fit over the duckbills. The "duckbill" check valves will protrude slightly through holes/ windows prepared for purpose and will discharge normally. Construction Due to operational requirements shut down of the pipelines must be well planned and durations kept to a minimum. Based on our feasibility studies the shutdowns are estimated to be no longer than 3 hours per pipeline. All the rehabilitation operations that require no flow through the pipe must be programmed to take place at the same time so that only one shut-down period is required. The following tasks will need to be completed under shutdown: • Disconnection of the flange adapter and replace. • Align the diffuser to vertical and temporarily secure. • Remove the diffuser Tideflex Check Valves. • Drop the protection sleeve into position. • Replacing the diffuser Tideflex Check Valves Divers to conduct the following site preparation activities. • Clearing loose rubble around the flange adapter and concrete base footprint. • Rock drilling may be required to level concrete base footprint. After Pipeline Shutdown • Replace/ rehabilitate and install: • Blank flange o Sacrificial break away spool piece (optional) • Flange Adapter - and right the diffuser to vertical alignment. • Remove the diffuser Tideflex Check Valves. • Place and secure precast concrete base • Drop the protection sleeve into position. • Replace the diffuser Tideflex Check Valves After Resume Pipeline Flow • Grout fill around flange adapter. • Place and secure protective sleeve cap. • A marker buoy with independent anchorage is also to be installed. Evidence of quality control measures and that the installation is as per design are required.
