BLM Issues Preliminary Determination for Visibility Milestone

The Bureau of Land Management (BLM) has reviewed current emissions data and has made a preliminary determination that Pinedale Anticline Project Area (PAPA) operators have met the requirements for Visibility Milestone #2 as stipulated in the 2008 Supplemental Environmental Impact Statement Record of Decision.

The preliminary determination is based on a combination of reported 2011 and estimated 2012 NOx (nitric oxide and nitrogen dioxide) emissions. The estimated emissions total of 1,618.28 tons/year is below the modeled threshold value of 1,703.5 tons/year which predicted an impact of 10 days or less of visibility impairment greater than one deciview within the Bridger Wilderness Area.

The Wyoming Department of Environmental Quality (WDEQ) will receive actual 2011 emissions inventories from PAPA operators by April 30. The BLM’s final determination of operator compliance with Visibility Milestone #2 will be based on the verified 2011 emissions data submitted to WDEQ and will be issued at the PAPA Annual Planning Meeting for Air Quality in August.
