As many of you know, the focus of my day job is Legionella control, but it does not stop there. I am active with ASHRAE, serving as Secretary of the SSPC 188 committee that developed and maintains the first standard to address Legionella in the United States. The need for my work to focus on this topic was, in part, spurred by the New York City and state regulations of 2015. I am also active within CTI's efforts in this area, on the committee developing Guideline 159, Practices to Reduce the Risk of Legionellosis Associated with Heat Rejection Equipment Systems. For those who are familiar with the development of this document or have been awaiting its publication, you know that this has taken quite some time. (Some of you may know that getting the ANSI/ASHRAE standard published also took a long time.) I am happy to report that the CTI Guideline 159 has been approved by the Board of Directors. Getting to consensus can be a journey when the goal is to provide a valuable product. As we enter 2020, other states, with the purpose of protecting people from the hazards of Legionella, appear to have proposed regulations for cooling towers on their legislative dockets. While I am happy to see reference to parts of the ASHRAE standard, it is in everyone's interest to review and carefully examine these proposed regulations and not speed down the road to approval.
