Background Ozone Background ozone is a significant issue, especially in the West Background ozone is 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 Colorado ~18-25 ppb 25-35% Interstate ~8-12 ppb 10-15% US Background ~42-47 ppb 55-60% 9
What can you do? Next board meeting: Friday 6 May at 9:30am at Chamber building Mower exchange: Sat 7 May at Dicks Sporting Good park (must pre-register) Ozoneaware: Everytripcounts.org : commit to reduce 2 car trips per week this summer Log trips: ozoneaware.org/calculator/ RAQC.org 10

New 2015 Ozone Standard - 70 ppb CAA section 109(d) requires EPA to review the scientific information and National Ambient Air Quality Standards every five years. In setting NAAQS, EPA may not consider cost. (Whitman v. American Trucking Associations, 531 U.S. 457, 473 (2001)) EPA was under court order to review standard by December 1, 2014 and finalize decision by October 1, 2015. EPA proposed a standard range between 65-70 ppb in Dec. 2014 EPA Administrator issued the final standard of 70 ppb on Oct. 1, 2015 17

Legal Challenges to 2015 Standard Some states and business groups have challenged the standard in court as being too stringent Other states and environmental/public health groups have challenged the standard as not being stringent enough In the meantime, EPA and the states are moving forward with the process to implement the standard 21
