The hydraulic fracturing boom is apparently creeping closer to the boundaries of Grand Teton National Park. National Parks Conservation Association Program Manager for Grand Teton National Park Sharon Mader says Wyoming is seen as a leader in requiring companies to divulge ingredients used in fracking. However, she says a report recently released by the NPCA lists air quality as still being a concern. Some development is taking place about 60 miles from the park – a distance the report says is expected to shrink in the years to come. Mader points out, “Prevailing winds can often carry pollutants that impair visibility as well as create health problems.” Mader says the National Park Service is being proactive with regard to air quality, including the recent installation of an air quality tower in the Park. Mader says the NPCA report recommends that the National Park Service partner with federal agencies to review oil and gas development plans.
