1 Project Plan for Baseline Ambient Air Monitoring near Potential Hydraulic Fracturing Zones in Lee County, NC Mike Abraczinskas, Deputy Director North Carolina Division of Air Quality Project Plan for Baseline Ambient Air Monitoring near Potential Hydraulic Fracturing Zones in Lee County, NC Mike Abraczinskas, Deputy Director North Carolina Division of Air Quality February 2013

2 Executive Summary Characterization of air emissions sources and identification of predominant air pollutants at potential hydraulic fracturing operations. Assessment of existing air quality monitoring network. Identified existing, well-placed upwind and downwind multi-pollutant air monitoring locations in Montgomery and Wake counties. –Sites near the Triassic Basin, but not within the area that may be considered most promising for shale gas production. Sanford sub-basin in Lee County –No existing air monitoring in Lee County. Recommendation: Establish a multi-pollutant air monitoring site in Lee County.

NC Air Quality Monitoring Network Deep River basin Sanford sub-basin Dan River basin Recommended air monitoring location

4 Other activities Expanding knowledge base –Emissions Inventory team –Permitting team Gathering information from other state air agencies where shale gas development activities are happening. Information will help shape DAQs approach.
