Ozone pollution at Carlsbad Caverns comes from oil and gas, study says

Air monitoring at Carlsbad Caverns National Park showed air pollution in the area increased in recent years alongside growth in oil and gas operations.  

New Mexico aimed to curb such impacts of extraction in the coming year as the State of New Mexico prepared to finalize new regulations aimed at ozone created by extraction.

The New Mexico Environment Department (NMED) announced a public hearing next month on the released draft of its ozone precursor rules, which would require oil and gas operators to reduce the emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NOx) from facilities used in fossil fuel production.

The chemicals combine with sunlight to create ground-level ozone, known to cause respiratory illness and cancer.
