Modeling the Impact of Oil and Gas Emissions on Ozone in New Mexico
Tammy M. Thompson, a Senior Air Quality Scientist at the Environmental Defense Fund, discusses the modeling of ozone from oil and gas production emissions in New Mexico. The analysis focuses on areas with high ozone concentrations and their overlap with oil and gas regions, highlighting the sensitivity of VOC emissions and their contribution to ozone formation. The study reveals the correlation between VOC sensitivity and ozone levels in different regions of New Mexico, emphasizing the local and downwind effects of VOC emissions on background ozone concentrations.

Comments on Modeling of Ozone from Oil and Gas Production Emissions in New Mexico Tammy M. Thompson Senior Air Quality Scientist, Environmental Defense Fund September 22, 2021
Ozone VOC Sensitivity is often highest in areas of relatively higher ozone We are most interested in areas with high ozone concentrations, and especially areas that overlap with O&G regions, so let s talk about the NOx/VOC sensitivity of those areas, not the state on average The modeling (NMED Exhibit 17, pp 158 184) shows, on high ozone days, the areas with highest MDA8 ozone are often co-located with the highest VOC sensitivity.
Location of modeled Oil and Gas emissions: NMED Exhibit 16 pp 52
The San Juan region shows both high contribution of NM emissions to ozone (left) and high VOC sensitivity (right) May 26, 2014 (pp 163)
Southeast NM shows both high contribution of NM emissions to ozone (left) and higher VOC sensitivity (right) May 28, 2014 (pp 164)
The San Juan region shows both high contribution of NM emissions to ozone (left) and high VOC sensitivity (right) June 5, 2014 (pp 166)
The San Juan region shows both high contribution of NM emissions to ozone (left) and high VOC sensitivity (right) July 12, 2014 (pp 167)
VOC emissions from Oil & Gas Production will produce ozone SOMEWHERE SOMEWHERE Often, especially in the San Juan region, ozone production from VOCs will occur locally And further downwind, VOC emissions from New Mexico Oil and Gas production will increase background ozone concentrations for everyone (in the Northern Hemisphere).
