STA Task Groups - Get involved and help shape the future of emission monitoring and guidance note database
Over the past 25 years the STA and our members have shaped the way emission monitoring is carried out not only in the UK but also worldwide, this has been managed by the STA task groups. Our health and safety task group was initially set up in 1996 and is our longest running task group, closely followed by the Quality and Technical task group. Over the years we have added to the groups to include Process Operators, Equipment Suppliers, Low Particulate Monitoring (LPM), 14181 and Carbon capture and Biogenic task groups, the aim of each of these groups is to identify and address challenges and potential issues.
HEALTH & SAFETY TASK GROUP
The safety of those undertaking stack emission monitoring has always been a driving force within the Source Testing Association and the Health and Safety Task Group is the focus of this work. Since its inception those involved in this group have strived to produce guidance to the industry on safe working practices and the implementation of safety legislation.
One of the most recognised publications of this group is the Risk Assessment Guide for Industrial Emission Monitoring, commonly known as the Yellow Book. Its adoption as the safety guide for the industry has resulted in its inclusion in the EA guidance and MCERTS scheme and it has remained a clear and concise guide to the potential dangers of the work we do. Its annual revisions has kept it up to date with the ever changing legislation whilst the group has strived to keep it as a simple and practical guide for those up the stack as well as a useful resource for managers, salesmen and process operators.
During the regular meetings, the task group members review changes to existing legislation and proposed new legislation and where necessary advise the STA members as to the potential implications of such legislation. Such advice is often provided as guidance notes published on the website. Accidents in the industry and in related industries are discussed and if lessons can be learnt then these are communicated through bulletins on the website or as e-mails.
of uncertainty, and the example uncertainty calculation spreadsheets. Members also have the opportunity to input in to EA guidance and CEN and ISO standards.
In addition the Quality and Technical groups also undertake specifi c projects, often with EA or DIUS support, to investigate particular issues related to stack testing methods.

PROCESS OPERATORS TASK GROUP
The Process Operators Task Group generally meet three times a year in conjunction with the other groups to review developments in legislation and standards and to share practical experience of continuous monitoring, quality assurance and related issues, such as permitting and reporting.
• The task group has also created an STA guidance document: AST Failings – best practice guidance
CARBON CAPTURE AND BIOGENIC TASK GROUP EQUIPMENT SUPPLIERS TASK GROUP
Representing the manufacturers and distributors of particulate and gas CEMs, portable instrumentation, sampling equipment and calibration gas suppliers, the group focuses on being a focal point on regulatory, certifi cation and standards issues relevant to emissions monitoring with particular focus on technical issues. The equipment suppliers group provides a technical input into UK regulatory consultations related to emissions monitoring, the MCERTS certifi cation process, European and MID standards and is a forum for resolving issues common across equipment suppliers
QUALITY AND TECHNICAL TASK GROUP
The Quality and Technical task group specifi cally addresses those issues relating to improving the value and reliability of the results we provide to our customers as stack testers. The topics routinely discussed include profi ciency testing (PT) schemes, relevant CEN standards and EA method implementation documents, EN 14181 guidance, calibration techniques and the availability of calibration gases. In addition to a large number of stack testing companies, UKAS, EA, process operators and gas supply companies also attend the meetings, enabling issues and topics raised by members to be addressed in the meetings.
The Quality Task Group is active in producing guidance for members, including the STA Guide to the calculation
EN14181 TASK GROUP
The STA has been reviewing the requirements laid out in BS EN 14181 and EAs MID documents, this has been done via the 14181 task group, a great deal of progress has been made over the past few meetings, following topics were covered;
Stack fl ow requirements • MID EN ISO 16911-2 Accreditation • Sample Location requirements for planners • QAL3 for fl ow meters
The recently created Department for Energy Security and Net Zero (DESNZ) has the overarching mission of replacing the UK’s current energy mix with cheaper, cleaner, domestic sources. As a part of the journey to net zero by 2050, the UK will be powered by renewables, hydrogen, combustion with carbon capture, usage and storage (CCUS) and nuclear. The energy transition is a major technical and economic opportunity for the UK. Current government policy aims for energy independence by doubling the UK’s electricity generation capacity and fully decarbonising the power sector by the mid/late 2030s. In October 2017, the government’s Clean Growth Strategy set out ambitions to become a global technology leader for CCUS and has a target to capture and store 20–30 MtCO2/y by 2030.
This transition to net-zero also has technical implications for the future of source testing. The advent of CCUS will require measurement techniques to be developed to quantify carbon capture rates, process solvent and degradation product emissions in order to meet regulatory requirements
All STA members, whether instrument suppliers, test houses, regulators or process operators are going to be fundamentally impacted by these changes. Therefore there is a need for the STA, as an impartial organisation committed to the enhancement of the science and practice of emission monitoring, to constantly review its activities in response to the evolving needs of its members.
The STA has established a task group to support members through the forthcoming energy and net zero transition. The fi rst stage of the process has been to identify the terms of reference of the working group and focus its efforts on areas of interest to members.
YOUR STA
The STA meetings and task groups are available for all STA members to attend and contribute. If you are an existing STA member and not already involved in the valuable work the STA does or if you are interested in becoming a member, please email
info@s-t-a.org and one of the team will contact you.
