EPA Proposed NA Boundary: Metropolitan Statistical Area

Atascosa, Bandera, Bexar, Comal, Guadalupe, Kendall,

Medina, and Wilson Counties

Mandatory control strategies to reduce ozone are

implemented within the region contained in the final

nonattainment (“NA”) boundary

Ozone Compliance - 2014

* As of April 22, 2014, TCEQ

San Antonio Northwest C23 81 76 56 71Camp Bullis C58 87 83 62 77Calaveras Lake C59 70 69 56 65

2008 8-hr. av. O3 National Ambient Air Quality Standard: To attain this standard, the 3-year average of the fourth-highest daily maximum

8-hour average ozone concentrations measured at each monitor within an area over each year must not exceed 75 ppb (parts per billion).

The 3-year average described above is the single critical measure of compliance.

Ozone Season: April 1 – October 31. Calendar year data required for compliance.

Most Current (1/29/2014) Timeline

• July 2014: Review Process of 2008 Ozone Standard Ends

• January 2015: Proposed Rulemaking for Revised Ozone Standard

• September 2015: Final Rulemaking published

• September 2016: Nonattainment Designation Recommendations from Governors due to EPA; based on local monitoring data

• May 2017: EPA Proposes Nonattainment Designations No Later Than This Date (120 day letters)

• September 2017: EPA Nonattainment Designations Final

Implies that 2014-2016 will be theyears of record for ozone compliance

DRAFT

Will there be a New Ozone Standard?

DRAFT

“NOx Limited” => to reduce ozone, we need to reduce NOx
