  3. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Overview of the Regional Haze Program • Regional Haze is the impairment of visibility due to air pollutants from anthropogenic sources (40 CFR 51.301) • Stationary, mobile, and area emission sources, over a wide geographic area, contribute to visibility impairment • Primary mechanism of visibility impairment is light extinction caused by particulate matter 3

  7. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Overview of the Regional Haze Program • 1999 - EPA adopted the Regional Haze Rule to protect Federal Class I areas from visibility impairment – Requires states to develop Regional Haze SIPs and revise them every 10 years • 2012 - EPA approved Missouri’s first Regional Haze SIP • 2017 - EPA revised the Regional Haze Rule - the 2 nd SIP revision deadline was extended from 2018 to 2021 7

  12. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Planning and SIP Development • Ultimate goal: Attain natural visibility conditions in all Federal Class I areas by 2064 • States required to develop ten-year plans to achieve the goal with a Uniform Rate of Progress • EPA approved Missouri’s 1 st Regional Haze SIP in 2012 and Missouri’s first Regional Haze progress report in 2016 12

  13. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Planning and SIP Development • States must revise and submit their regional haze implementation plan revisions to EPA by July 31, 2021, July 31, 2028, and every 10 years thereafter • States must submit Regional Haze progress reports to EPA every five years • States must address all Class I areas located within their state and those located outside the state that may be affected by emissions from within the state 13

  14. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Current Status and Future Plans • August 20, 2019 - EPA released guidance for development of Regional Haze SIPs for the second implementation period • The guidance proposes an eight-step SIP development framework 14

  15. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Current Status and Future Plans Step 1: Ambient data analysis (completed) Step 2: Determination of affected Class I areas in other states Step 3: Selection of sources for four-factor analyses  costs of compliance,  the time necessary for compliance,  the energy and non-air quality environmental impacts of compliance, and  remaining useful life Step 4: Characterization of factors for control measures 15

  16. E MISSOURI --m DEPARTMENT OF NATURAL RESOURCES ============== ------- ------- ------- a!:111 Current Status and Future Plans Step 5: Decisions on necessary control measures for reasonable progress goals Step 6: Modeling of long term strategy Step 7: Uniform Rate of Progress glide path check Step 8: Consultation with other parties (FLMs, other states) 16
