Update on 2008 Ozone NAAQS Implementation.

May 1, 2015

Trinity Consultants has published an informative update on implementation of the U.S. Environmental Protection Agency (EPA) 2008 Ozone National Ambient Air Quality Standards (NAAQS).epa logo

Both the primary and secondary standards were promulgated on March 12, 2008 and became effective on May 27, 2008. The 8-hr ozone NAAQS was set in 2008 at a level of 0.075 ppm. Once a NAAQS is promulgated for a criteria pollutant, area designations need to be assigned; and this occurred by July 20, 2012 for this ozone standard.

A full list of Non-attainment Areas can be found on the United States EPA’s Green Book Non-attainment Areas for Criteria Pollutant. Non-attainment area designations are: Extreme, Severe 15, Serious, Moderate, and Marginal.

The EPA published a final rule in the Federal Register on March 6, 2015, regarding the “Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State Implementation Plan Requirements“. This rule addresses a range of non-attainment area state implementation plan (SIP) requirements for the 2008 ozone NAAQS, including those requirements which pertain to demonstrating attainment, reasonably available control technology (RACT), reasonably available control measures (RACM), reasonable further progress (RFP), major new source review (NSR), emission inventories and emission control measures in the SIP submissions as well as compliance with emission control measures in the SIP.

Areas designated marginal non-attainment have three years from the date of last designation (i.e., July 20, 2015) to show attainment with the 2008 8-hr. ozone NAAQS. The attainment status is determined based on the ozone monitoring data from 2012 to 2014. If the monitoring data (over the reviewed time period) is threatening the area designations, per the provisions of the Clean Air Act (CAA), a state can request for a 1 to 2 year extension for showing attainment if the existing monitoring data meets certain criteria.

The rule also discusses the revoking of the 1997 ozone 8-hr standard (effective April 6, 2015); and the applicable anti-backsliding requirements that apply when the rule is revoked. Anti-backsliding requirements are for retaining and preserving the air quality improvements that were achieved under the previous NAAQS.

If the primary or secondary ozone NAAQS are revised in the future, the EPA expects that this rule will help facilitate implementation of any new standards. In November 2014, the EPA proposed lowering the ozone standard to a range between 65-70 ppb. By court order, the Agency must finalize the standard by October 1, 2015.

What this means to you
EPA published a final rule on March 16, 2015 regarding state implementation plan (SIP) requirements for implementing the 2008 NAAQS for ozone. Areas designated marginal non-attainment have three years from July 20, 2015 to show attainment for the 2008 standard (75 ppb). In November 2014 EPA proposed lowering the standard to a range between 65-70 ppb. EPA is under court order to finalize the standard by October 1, 2015.
