White River National Forest Oil and Gas Leasing Environmental Impact Statement

White River National Forest Oil and Gas Leasing Environmental Impact Statement

White River National Forest Oil and Gas Leasing Environmental Impact StatementWREG 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.

Transmission Line Environmental Impact Statements

Transmission Line Environmental Impact Statements

Transmission Line Environmental Impact StatementsWREG prepared the air quality analyses and sections for two Environmental Impact Statements (EISs) for proposed transmission lines in Utah. The first EIS was for the Mona to Oquirrh Transmission Corridor Project. Rocky Mountain Power, a division of PacifiCorp, applied to the Bureau of Land Management (BLM) for a right-of-way grant to use public lands for portions of the Project. The BLM was the lead federal agency for National Environmental Policy Act (NEPA) review and preparation of the EIS. WREG prepared emission estimates and impact analyses for transmission line construction activities, including mobile source emissions, heavy equipment emissions, paved and unpaved road dust, fugitive dust from earthmoving activities, and construction and operation of a concrete batch plant. Emissions and impacts were also evaluated from construction or expansion of substations. Because the project traversed portions of several nonattainment areas, a detailed general conformity analysis was also conducted.

WREG also prepared air quality analyses and document sections for Rocky Mountain Power’s proposed Sigurd to Red Butte No. 2 345kV Transmission Project EIS and for the initial geotechnical investigation. In addition to the emission source types evaluated for the Mona-Oquirrh project, WREG determined emissions from helicopters proposed for use in both the geotechnical work and during transmission line construction. A total of 12 alternate routes were evaluated, as well as expansion of two existing substations and construction/operation of a concrete batch plant.

Power Plant Environmental Assessment Review

Power Plant Environmental Assessment Review

Power Plant Environmental Assessment ReviewWREG prepared a comprehensive review of the air quality analyses for a proposed natural gas-fired electric generating station Environmental Assessment (EA). The proposed project would operate as a peaking facility during periods of high energy demand, along with a combined-cycle facility to provide a year-round source of energy. The proposed facility would be located near Primm, Nevada, in southern Clark County.

Generating Station Environmental Impact Statement Review

Generating Station Environmental Impact Statement Review

Generating Station Environmental Impact Statement ReviewThe Bureau of Indian Affairs (BIA), in cooperation with the Bureau of Land Management, prepared an Environmental Impact Statement (EIS) for a 760 megawatt generating station to be located on an Indian reservation in Clark County, Nevada. WREG assisted the BIA in the review of the EIS and the environmental documentation associated with preparation of the EIS. WREG conducted a comprehensive air quality technical review of the EIS and associated documentation.
