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.

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).
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.

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).
