As we do each year, ALL4 looks ahead to the upcoming new year and evaluates the air quality regulatory topics that may matter most to the regulated community. For 2016, it certainly will be the year of Boiler MACT, as facilities gear up to prepare plans and conduct performance testing. We see a continuing trend of electronic reporting and public access to such data. Finally, Federal enforcement initiatives and recently implemented programs are driving new monitoring requirements for affected facilities that will require collaboration between industry, consultants, and equipment vendors. We welcome your feedback on these, and other topics, as you read our articles on what will be hot in 2016.
