4. Ozone Compliance - 2014 * As of April 22, 2014, TCEQ Regulatory Monitoring Sites Fourth Highest (ppb) Current* 3-Year 201220132014*Average San Antonio Northwest C2381765671 Camp Bullis C5887836277 Calaveras Lake C5970695665 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.
