- The pollutants included in our analysis “have fairly short atmospheric lifetimes and can only travel short distances.” As a result, only a small proportion of subjects included in these studies could reasonably be expected to have any exposure to these pollutants from shale development operations via the air pathway.
- Potential exposure from oil and gas (O&G) operations “vary both spatially and temporally, and act over short distances and time scales.” WA models assume that all wells, in the same phase of development (the durations of which were predetermined, not based on actual well data), continuously emit pollutants in all directions. There is no consideration of varying meteorological conditions mentioned by Buonocore et al. (e.g., wind direction, cloud cover, wind speed). None of these are realistic assumptions.
- The pollutants included in our analysis are not unique to shale development, but rather “come from a number of sources common in the area including vehicular traffic, combustion of coal and gas for electricity generation and home heating, not to mention natural gas processing and existing conventional O&G wells.” WA models do not take any of these other point and mobile sources into account. This is especially significant given that the models estimate exposure for study subjects who are, for the most part, far from any unconventional development.
