Annual Guide 2022 I SOURCE TESTING ASSOCIATION


Chairman’s introduction to the 2022 STA Annual Guide


Welcome to the 2022 STA Annual Guide. The STA is a not-for-profi t organisation that was set up in 1995 to serve the emerging needs of emissions monitoring industry. We continue to exist to serve the needs of our diverse range of members. Uniquely, we bring together operators, regulators, test houses, equipment suppliers, consultants, and certifi cation bodies in an accessible and supportive forum united around the common goal of enhancing technical standards in emissions monitoring. I sincerely hope we continue to meet this simple goal.


It is reassuring and refreshing to see that the emissions monitoring community has continued to deliver high quality equipment, analytical services, technical support, advice and guidance to customers all across the UK and beyond despite the considerable challenges of COVID-19.


Stewart Davies, Head of Technical Compliance, Viridor


As we continue to emerge from the considerable challenges posed by the pandemic we hope that 2022 will be much more “normal”. It’s also worth noting that the challenges of the last 2 years have caused the STA to review what the future normal looks like. The STA is not alone in looking to adapt it ways to meet the needs of the future. Remote working and Teams/Zoom calls have become second nature to most of us. Many of us travel far less frequently than we used to. These changes are here to stay and bring benefi ts not only to organisations in terms of effi ciencies and cost savings but also to individuals in balancing home and work life.


It has been so heartening to see the continued high-level of attendees at online STA meetings. Numbers continue to exceed our expectations. Going forwards we will adopt a “hybrid” approach, blending the best aspects of traditional face-to-face meetings with the benefi ts of online attendance. Hopefully we will benefi t from the diverse geographic spread of our members and hold our hybrid meetings at locations all across the UK.


To reinforce the long-term viability of the STA we took the diffi cult decision to surrender the lease on our offi ces at Hitchin at the end of the year. In order to provide continuity of service, we have taken out a short-term lease on a serviced offi ce nearby. We will review the effectiveness of these changes upon the service offered to members and please be assured that quality of service remains our highest priority.


At the point I would like to extend my gratitude to Simon Medhurst and Paul Mudway, who have adapted and developed the STA’s training programmes for online delivery. Relevant and cost-effective training underpins the STA’s ethos and their considerable efforts the year have been truly vital is supporting the STA through the last year. As always, Sam Harvey and Andy Curtis have endeavoured to maintain the STA’s customer and technical service whilst our elected Offi cers continue to give of their time in support of our aims. I also wish Alison Sampson all the very best in assuming the role of Chair in 2022, a very well-deserved appointment in recognition of her considerable contribution to the emissions monitoring community.


Finally, as a reader with an interest in emissions testing, I would like to thank you for your continued support over the last 12 months. It has been truly invaluable. Let us all hope that 2022 returns to something more normal!
