Description

United Utilities (UU) require LDAR surveys to be completed at Anaerobic Digestion facilities , located at in the North West of England. • The survey is to be carried out at a 6 monthly frequency with the ability to increase this frequency when enhanced monitoring is required on a site by site basis. • The scope of the LDAR survey is biogas assets and associated equipment. • The survey is to detect fugitive emissions of Volatile Organic Compounds (VOC’s) and other substances to air including methane. • Operators undertaking the survey must have sufficient competence to undertake surveys safely on active gas assets and must be familiar with DSEAR. • Operators must adhere to UU permitting and induction requirements. • LDAR survey methodology must fully comply with EA guidance Biological waste treatment: appropriate measures for permitted facilities (2024) Section 11.9 - Leak Detection & Repair. The survey should utilise the Optical Gas Imaging (OGI) method using hand-held cameras to enable visualisation of gas leaks with quantification of emission rate and emission concentration. • A report must be provided in the format specified in EA guidance Biological waste treatment: appropriate measures for permitted facilities (2024) Section 11.9 - Leak Detection & Repair. This should be accompanied by a detailed emissions list with OGI footage of each emission. This should be issues no later than 5 working days of the visit. • Reports and emissions lists should be available on a secure portal that records video of emissions. • Emissions should be tagged onsite using an agreed methodology. • Contractors undertaking LDAR analysis must liaise with UU Regulatory and Statutory Maintenance team to arrange visits in aligned to a pre agreed schedule as per UU's third party scheduling procedure. • All emissions must be physically identified to the site operational contact at the end of the survey visit. • Provision for emergency call out and response within 24 hours. • Monitoring equipment, techniques, personnel and organisations shall have either MCERTS certification or MCERTS accreditation (as appropriate ).
