WREG prepared the air quality specialist report for the White River National Forest (WRNF) Oil and Gas Leasing Environmental Impact Statement (EIS) Revision. The WRNF made an oil and gas leasing decision in 1993 that made 1.5 million acres of the WRNF in Colorado available for leasing and imposed stipulations on some of the lands when leased. In 2008, the WRNF prepared an EIS to review and update the 1993 Oil and Gas Leasing Final Environmental Impact Statement (FEIS) and Record of Decision (ROD).
In completing the air quality specialist report, WREG addressed designated indicators, including emissions related to vehicles, heavy equipment, and diesel generators; emissions related to temporary venting or flaring of natural gas; greenhouse gases and climate change; noise and odor; near-field air quality from fugitive dust during construction activities; near-field air quality related to operation and maintenance of well facilities; effects on air-quality-related values (AQRVs) including visibility impairment (regional haze) and acid deposition at Class I and sensitive Class II areas; compliance with Colorado and National Ambient Air Quality Standards (NAAQS); and compliance with Wilderness Act requirements to maintain or enhance conditions in designated wilderness areas. The impact analysis addressed how the next 20 years of oil and gas activity could affect each of the designated indicators.
