Benchmark: EPA’s Revised Secondary Sulfur Dioxide Standard Course
Take this benchmark to assess how much you would benefit from taking the course on the EPA’s review of secondary NAAQS for oxides of nitrogen, oxides of sulfur, and particulate matter—especially the revised secondary SO2 standard effective January 27, 2025.
What you’ll get from this benchmark:
– A quick read on whether you grasp why the SO2 secondary standard shifted to an annual, ecosystem-focused metric—and what that means in practice.
– Clarity on who is most affected (ecosystems, downwind/rural communities) and how that connects to environmental justice.
– Insight into operational impacts: monitoring network design, data completeness, and interpreting the 3-year form.
– Awareness of Clean Air Act implementation touchpoints: area designations, SIP obligations, PSD/NNSR permitting, and general conformity.
– A sense of your readiness to explain the “why” to stakeholders and make policy or permitting choices that withstand scrutiny.
Use your results to decide:
– If you need the full course to close gaps in policy intent, equity implications, or implementation mechanics.
– Whether your organization should adjust monitoring strategies, SIP planning, or permitting workflows before the revised standard drives decisions.
If several questions feel uncertain or you find yourself choosing answers based on old short-term SO2 thinking, the course will help you quickly get current—and avoid missteps in designations, SIPs, and permits.
