The U S EPA has announced their proposed NAAQS for ozone; in the range of 65-70 ppb. They will also taking comments on NAAQS set as low as 60 ppb.
The complete announcement can be found at http://www.epa.gov/airquality/ozonepollution/actions.html#nov2014
EPA will take final action on the proposed standards by Oct. 1, 2015. Based on that date, the agency anticipates the following schedule for making area designations, if EPA revises the standards:
o By October 1 2016: States recommend the designation for all areas of the state, or any relevant areas in Indian country, and the boundaries for those areas.
o By June 1, 2017: EPA responds to states’ initial recommendations and identifies where the agency intends to modify the recommendations. States will have the opportunity to comment on EPA’s response, and to provide new information and analyses for EPA to consider.
o By October 1, 2017: EPA issues final area designations; those designations likely would be based on 2014-2016 air quality data.
o 2020 to 2021: States complete development of implementation plans, outlining how they will reduce pollution to meet the standards. State and tribal plans can include federal measures, and any local or statewide measures needed to demonstrate that a nonattainment area will meet the standards by its attainment date.
o 2020 to 2037: States are required to meet the primary (health) standard, with deadlines depending on the severity of an area’s ozone problem.
Our current ozone averages are 67 ppb at CAMS 4 and 66 ppb at CAMS 21. At our January meeting we will discuss the proposed NAAQS for ozone and plans to participate in the public comment period.
