Presented to the 2016 Texas Transportation Planning Conference

June 16, 2016


Overview

• Ozone NAAQS and Trends • Implementation of the Standard • Conformity (General and Transportation) • Designation Recommendations


National Ambient Air Quality Standards (NAAQS)

• Required by the Federal Clean Air Act (FCAA) • Set by the United States Environmental

Protection Agency (EPA) • Health and welfare based standards set for

six criteria air pollutants: – Ground-Level Ozone (O3) – Particulate Matter (PM) – Nitrogen Dioxide (NO2) – Sulfur Dioxide (SO2) – Carbon Monoxide (CO) – Lead (Pb)


2015 Eight-Hour Ozone NAAQS

• On October 1, 2015, the EPA lowered the NAAQS for ground-level ozone to 70 ppb.

• Based on preliminary air monitoring data for 2015, the Dallas-Fort Worth, Houston-Galveston-Brazoria, San Antonio and El Paso areas are measuring levels above the new ozone standard. – State recommendations expected to be based on

the 2015 Design Value – Final EPA designation expected to be based on the

2016 Design Value

Based on Section 181(a)(1) of the Federal Clean Air Act: Marginal 2020 Moderate 2023 Serious 2026 Severe 2032 or 2034 Extreme 2037


Nonattainment: Federal Requirements


Transportation Conformity • Ensures that metropolitan transportation plans,

transportation improvement programs, and projects funded by the Federal Highway Administration or Federal Transit Administration are consistent with the air quality goals established in the SIP and do not: • cause new NAAQS violations; • worsen existing NAAQS violations; or • delay achievement of interim milestones or timely

attainment of the NAAQS • Required for new nonattainment areas one year after

effective date of designation and at least every four years in nonattainment and maintenance areas

• Requires motor vehicle emissions budget (MVEB) test or interim tests


Transportation Conformity • MVEB Test (40 CFR §93.118)

• Required for areas with adequate or approved MVEBs, including MVEBs from previous NAAQS for existing non-attainment areas

• Interim Tests (40 CFR §93.119)

• Required for areas without adequate/approved MVEBs • Newly designated areas classified as marginal

• Either Build ≤ No Build OR Build ≤ Baseline • Newly designated areas classified as moderate and above

• Both Build < No Build AND Build < Baseline


General Conformity • Ensures that federally funded actions in nonattainment and

maintenance areas that are not covered under transportation conformity are consistent with air quality goals established in the SIP

• Required for new nonattainment areas one year after effective date of designation

• Triggered when emissions from federal action are expected to equal or exceed de minimis thresholds (40 CFR §93.153)

Designation / Classification Threshold

Nonattainment / Marginal 100 tpy

Nonattainment / Moderate 100 tpy

Nonattainment / Serious 50 tpy

Nonattainment / Severe 25 tpy

Nonattainment / Extreme 10 tpy

Attainment (Maintenance) 100 tpy


State Designation Recommendations

• Designation recommendations made by Governor with input from TCEQ

• TCEQ considering nonattainment designations for counties: • with regulatory monitored 2015 design values

exceeding 70 ppb and/or • are currently designated as nonattainment for the

2008 ozone standard

• Areas monitoring above the 2015 ozone NAAQS based on 2015 design values: • DFW 10-County nonattainment area (83 ppb), HGB

8-county nonattainment area (80 ppb), Bexar County (78 ppb), Hood County (73 ppb), and El Paso County (71 ppb)


Recommended Nonattainment Areas Under the 2015 Ozone Standard


State Designation Recommendations

• 32 public comments received • The commission is scheduled to consider

staff’s recommendation at its August 3, 2016 meeting.

• If approved by the commission, the recommendation will be submitted to the governor’s office for consideration.

• Recommendations are due to the EPA by October 1, 2016.

• The EPA’s 120-day notice is expected on June 2, 2017.
