On a hot, dusty day in August last year, a group of regulators from the New Mexico Environment Department and the Energy, Minerals and Natural Resources Department traveled to Counselor, New Mexico, to tour the oil and gas sites that dot the landscape of the Greater Chaco region.
The group included NMED’s Air Quality Bureau chief Elizabeth Bisbey-Kuehn, Environmental Protection Division director Sandra Ely, NMED Secretary James Kenney and EMNRD Secretary Sarah Cottrell Propst — all key regulatory figures in the state’s Methane Advisory Panel, tasked with developing new regulations around oil and gas emissions. Teresa Seamster, Navajo Nation Counselor Chapter Health Committee member, used the opportunity to present the findings of a recently completed health impact assessment (HIA), which found periodic spikes of formaldehyde and other pollutants associated with oil and gas development, recorded at unsafe levels for short periods of time near homes.
“Formaldehyde is probably one of the most carcinogenic chemicals in air that you can have,” Seamster told NM Political Report. “It will cause irritation of the respiratory tract, it can lead to throat and nose cancer, chronic respiratory inflammation and bronchitis, it’s definitely something you do not want in the environment, and we were getting it in the open air at levels that require mitigation.”
“Formaldehyde was detected at all sites at unhealthy levels,” she added.
Seamster and other volunteers from the chapter conducted the study under the guidance of the Environmental Health Project, a nonprofit public health organization that conducts scientific air quality monitoring for communities near oil and gas development. The report is currently unpublished — and will likely remain so until the COVID-19 pandemic subsides and the Navajo Nation government is able to reopen — but NM Political Report obtained a copy. It’s also the latest in a growing body of evidence, codified into multiple peer-reviewed studies conducted across the country, that indicates communities situated near oil and gas development are exposed to hazardous pollution at higher levels than either state or federal regulatory agencies recognize.
