iv UK Focus STA Focus


The STA continues to support its members in a number of ways, one of the key ways is by our task group meetings, these meetings are the main driving force of the STA which allow Test laboratories, Equipment suppliers, Process operators, Regulators, Certifi cation and Accreditation bodies, to come together and discuss relevant topics and issues arising. Our latest general meeting, which is split into 4 sub-groups; Health and Safety – Quality and Technical – Process Operators and Equipment Suppliers, had full agendas covering topics like:


Health and Safety • Accidents and incidents. Which included a Presentation on working in extreme heat looking at exposure to the sun, heat stress, heat exhaustion heat stroke as well as how to treat and protect yourself


• WAH Incidents • Feedback From HSE


Quality and Technical Task Group • UKAS accreditation and issues arising • Regulators/Certifi cation Bodies • Feedback from other STA task group e.g. EN14181 task group update which covered Stack fl ow measurements issues – Method Implementation Document, (MID), Stack fl ow measurements issues – QAL3 capability of fl ow monitors, CO2 and N2O measurement at EfW plant, AST failures, Data Acquisition and Handling Systems (DAHS), Sample port compliance at new plants, Issues associated with low concentrations, NOx calibration functions, NO2 directly or total NOx using a converter, fi nal reportable NOx concentration, NO2 mg/m3


• Profi ciency Testing Schemes NPL PT schemes for 2023 Effectech SEPTS scheme 2023 LGC Air and Stack Emissions PT scheme • Standards bodies – CEN and ISO feedback


• STA training courses The STA continues to provide training to members and non- members as demand dictates. Following travel restrictions associated with COVID-19, the STA has been offering on-line training since July 2020. Numbers attending the training courses have remained buoyant in over the last year. Courses include: o Risk Assessment - Industrial Emission Monitoring o Regulatory Monitoring Requirements for Process Operators o On Site Auditing o BS EN14181 quality assurance of an AMS o Medium Combustion Plant Directive and Specifi ed Generator Regulations


o Foundation Course- Introduction to MCERTS Level 1 o MCERTS Level 2 – Team Leader – new two-day online course – under


o development o MCERTS Technical endorsements TE1 – particulate monitoring TE2 – Trace element (dioxins, metals etc) measurement TE3 – Gaseous measurement by manual extractive measurement


TE4 – Gaseous measurement by instrumental analysers • Events & Publicity


Equipment Suppliers Task Group • DAHs responsibility – referred from EN14181 task group The group discussed the responsibilities of 17255-4. • N2O monitoring Process Operators Task Group • BREF Update • Carbon and Biogenic task group update


• Medium Combustion Plant (5-50 MW) • Feedback from Pos • Future Plans for POTG We also support our members in a number of other ways which include telephone and email support, through our website that has a wealth of information in the public and members areas and via our industry specifi c guidance notes. Since its formation the STA has provided practical guidance for members on the management of risks to health and safety that may arise in relation to specifi c hazards within our industry. The guidance doesn’t stop there, the association also produces guidance notes on Quality and Technical issues enabling members to have the information and knowledge they require to assist them to provide the highest quality of service.
