Ozone and Particulate Matter Status

St. Louis Nonattainment Area Historical Current (prior to 2019) 5

What does this mean for St. Louis? • Nonattainment New Source Review applies for ozone in St. Louis City, St. Louis County, St. Charles County, and Boles Township in Franklin County. PSD permitting applies in all other areas. • Transportation conformity no longer applies for PM 2.5 , however, it continues for ozone due to a recent court decision. • State and federal emission control rules relied upon in previous plans continue to apply. 6

Sulfur Dioxide (SO 2 ) Status

2010 SO 2 Standard (75 ppb) • 2013: Two nonattainment areas designated Round 1: Existing (portions of Jackson and Jefferson counties). Monitors • 2018: Monitoring attainment for both. Round 2: Consent • 2015-2016: Three areas considered. EPA did Decree not designate any nonattainment areas Round 3: Data • Dec 2017: EPA designated remaining areas Requirements Rule in Missouri as unclassifiable/attainment.

State Plan Actions in 2019 • 2015 Ozone Standard – Infrastructure SIP (Adoption Request at March 28 MACC meeting) – Transport SIP (Public Hearing at March 28 MACC meeting) • 2010 SO 2 Standard – Jackson County Maintenance Plan – Boundary Recommendations for undesignated areas 11

Federal NAAQS Updates • CO, Lead and NO 2 : EPA has not released an update • SO 2 : On Feb. 25, 2019, EPA retained the 2010 standard, without revision • PM and Ozone: EPA is expected to release a proposal in early 2020 with a final rule to follow in late 2020 12

State Rulemakings

Red Tape Reduction • 100% of department rules reviewed – 101 rules in Title 10, Division 10 • 38% reduction in restrictive words • 20% reduction in total rules • 64% of department rules were amended/rescinded – Air: 20 rescissions and 40 amendments • Over 300 comments were received and considered 14

Red Tape Reduction (Cont.) • Last set of RTR air rules will become effective March 30, 2019 • Submitting state rules to EPA for inclusion in SIP, as appropriate – EPA approval of submittals is required before state rules will be federally enforceable – Approval could take up to 18 months per Clean Air Act 15

Beyond Red Tape Reduction • Additional rulemakings expected in 2019 – Approximately 46 additional rules in review • These rules were delayed due to workload and priority. • Changes include rule clarification, reference updates, and addition of definition(s) • Workgroup for 10 CSR 10-6.410 forming 16
