Description

Total Quantity or Scope

The Environment Agency (EA) requires a Supplier to provide the Central Management and Control Unit (CMCU) and the Quality Assurance and Quality Control (QA/QC) for the UK Hydrocarbon Monitoring Network from 1st September 2024 until 31st August 2029. The main functions of the networks are to provide information about:• Compliance with the EU Ambient AQSR.• The long-term trends of hydrocarbons in mainly urban areas• The accuracy of the volatile organic compound’s emission inventory and subsequent ozone modelling.The networks consist of five (5) interdependent elements:• The monitoring sites containing EA owned monitoring equipment maintained under the contract. The equipment at the monitoring sites is in either self-contained structures owned by LA’s or the EA but managed under other Air Quality contracts.• In the automatic network, preliminary data analysis and storage instrumentation that the Supplier will need to provide. • In the automatic network, there is a telemetry system.• Quality assurance and quality control of the network and the monitoring data and a central data assessment, storage, and dissemination unit (DDU) (which is operated under contract by DEFRA) and is not part of the tender.The Hydrocarbon Network Operator is responsible for the management of a national network of air pollution monitoring sites throughout the UK for the measurement and assessment of Benzene (as non-automatic sites and automatic sites) as well as volatile organic compounds at automatic sites. The operator will be responsible for upkeep, collection, analysis QA/QC and transfer of automatic and non-automatic data to contractors who have responsibility for wider dissemination of the data. Objectives of the ProgrammeThe objective of the Automatic Hydrocarbon Network is to continue delivery and encompass new monitoring using automatic analysers that can measure additional hydrocarbons to align with changes to the pollution climate of the UK.The network provides information on:• Concentrations of twenty-nine (29) hydrocarbons in urban and rural areas to investigate long term trends.• To ensure the UK’s compliance with the EU Air AQSR for benzene and the requirement to monitor ozone precursors. • To validate and improve the accuracy of the UK’s volatile organic compounds emissions inventory and subsequent ozone and secondary particulate modelling.All monitoring (automatic and non-automatic) and QA/QC procedures must be compliant with any European Committee for Standardisation (CEN) standards produced for benzene.
