Ozone: Violations, NonAttainment & our Air Quality Future Peter Bella Alamo Area Council of Governments Guadalupe County Workshop / Randolph Metrocom Chamber October 9, 2012
Key Questions Today 1. What does the ozone violation mean? 2. What actions has San Antonio taken to reduce its contribution to ozone? 3. Why are all counties in San Antonio – New Braunfels Metropolitan Statistical Area (MSA) included? 4. What can surrounding counties do to reduce their ozone contribution? 5. What kinds of sanctions might ensue? 6. What is the role of what we call "transport”? 7. Will the Eagle Ford possibly increase area ozone?
What is ozone? Ozone is an odorless, colorless gas. Ground-level ozone can cause: –shortness of breath –coughing or wheezing –headaches nausea –throat and lung irritation Ground-level ozone’s effects are most profound on children, the elderly, and those with reduced lung capacity.
What Causes Ozone? Oxides of Nitrogen ( NOx ) & Volatile Organic Compounds ( VOC ) Note: NOx = NO + NO2 (<= criteria)
Emission Trends for VOC and NOx in San Antonio / New Braunfels MSA 1996 to 2018 San Antonio 8-County MSA Population

Violation: the three year average of ozone levels on local monitors was too high. On August 21, two monitors violated the 2008 ozone standard.

Requirements vs. Discretion Requirements: The current 2008 ozone standard is now under review: – May be revised in 2013 according to the five-year review cycle. IF the standard revised in 2013, and timeline did not change: – Proposal for a revised standard would be published in 2013 – Final standard promulgated in – Nonattainment designations promulgated in Designations would be made based on data. Next summer: possibly the 1 st year in the 3-year average for designations under a more stringent ozone standard. Now is a great time to initiate dedicated air quality improvements.
Requirements vs. Discretion EPA’s Discretion: It is within the EPA Administrator’s discretion under the Clean Air Act to notify the Governor of any state that a designation revision should be revised. – “…on the basis of air quality data, planning and control considerations, or any other air quality-related considerations the Administrator deems appropriate...“ Now is a great time to initiate dedicated air quality improvements, especially in light of the Ozone Advance program.
What is AIR Committee Doing? Ozone Advance –EPA program to provide assistance to areas interested in staying in attainment –Voluntary program for voluntary progress –If we are subject to a nonattainment designation, AND we have implemented adequate reduction, EPA administrator MAY allow time.
What is AIR Committee Doing? Ozone Advance –Outreach to local business and industry TERP: Cleaner fuels for cleaner fleets Catalogue existing “clean” practices –June 25, 2013: “Path Forward” letter to EPA with list of control strategies to put in place Eagle Ford Shale (EFS) Emissions Inventory for Ozone Precursors –Develop best estimations for activities –AACOG staff under contract with TCEQ

Key Programs under NA Nonattainment New Source Review: – Seeks industry and business emission reductions – Allowances are reduced under emissions permits Transportation Conformity – Requires that engineers demonstrate that “added capacity” roadway projects will not add pollution – One year from the date of a non-attainment designation, federally funded highway and transit projects require demonstration: no increase in emissions due to build-out
RACT/BACT/LAER BACT, or Best Available Control Technology, is required on major new or modified sources in clean areas (i.e., attainment areas). RACT, or Reasonably Available Control Technology, is required on existing sources in areas that are not meeting national ambient air quality standards (i.e., non- attainment areas). LAER, or Lowest Achievable Emission Rate, is required on major new or modified sources in non-attainment areas. Under EPA's "New Source Review" (NSR) program, if a company is planning to build a new plant or modify an existing plant such that air pollution emissions will increase by a large amount, then the company must obtain an NSR permit.
