Ozone Planning Primer

February 6, 2019 3

• Very complicated situation changing rapidly so my goal is a high

level overview of the ozone situation, provide you with some take home materials and invite you to participate in our efforts.

• Today I will cover:
• Who is the RAQC?
• Overview of the Denver/NFR Ozone Compliance
• Ozone Planning
• 2008 SIP Planning
• 2015 SIP Planning
• Conclusions

Overview

February 6, 2019 4

Lead air quality planning agency for the 9 county Denver Metro/North Front Range created by EO of the Governor Primary responsibilities

• Planning to meet federal air quality

standards (SIPs) and state standards

• Conduct programs of public education

and awareness

• Implement public/private projects to

reduce emissions and improve air quality

• Represent and assist local governments

in the air quality planning process

▪ Federal On-Road and Non-Road Mobile Source Standards/Regulations ▪ Inspection and Maintenance Program ▪ Oil and Gas Regulations ▪ 7.8 Reid Vapor Pressure (RVP) with 1 PSI Ethanol Waiver (8.8 RVP) ▪ Stage I Vapor Recovery at Gas Stations ▪ Power Plant Emissions Reductions – Clean Air Clean Jobs & Regional Haze ▪ Other Stationary Source Regulations ▪ Reasonably Available Control Measures ▪ Non federally enforceable measures

▪ From energy efficiency programs, small business programs, expanding the use of electric vehicles, mower exchanges, and bicycle and pedestrian programs to name a few.

Control Measures in 2017 Inventory

Background Ozone

February 6, 2019 15

• Background ozone is a significant issue, especially in the West
• “Background ozone” is ozone arising from natural events and

non-U.S. anthropogenic sources

• Past and recent studies have shown >55-60% of high ozone in

NFR and Colorado due to background ozone

Planning Efforts for the 2008 (75 ppb) Ozone Standard

February 6, 2019 17

• We’ve identified sources of emissions
• Determined relative contributions
• Strategies will we use are already in process (AIM, etc.)
• Requires a demonstration of future attainment
• Clean Air Act allows states to flag and remove air quality data

influenced by exceptional events (EE)

• Colorado flagged 9/2 and 9/4 in 2017 due to significant

wildfire smoke influence and submitted documentation to EPA in May 2018

2008 Serious SIP Planning

Planning Efforts for the 2015 (70 ppb) Ozone Standard

• This work is complicated and much of the low hanging fruit is

gone.

• We are reducing NOx and VOCs and Ozone levels are trending

downwards.

• In the future we are focusing more on NOx sources
• 2008 SIP is due 5/2021 to EPA with a 7/2021 attainment date
• Strategies are already in process
• 2015 SIP is due 1/2023 with a 8/2024 attainment date
• Join us during our planning process.
