Air Toxics

• Leak Detection and Repair

• Industrial Flares

• Excess Emissions

Energy Extraction Initiative

Energy Extraction Initiative Goal

• By no later than the end of FY2016, investigate and address known land based natural gas extraction and production activities that may be causing or contributing to air and/or water impacts

Air Quality Impacts

• Pollutants: NOx, VOCs, HAPs, Methane

• Well Pads – high emissions, not highly regulated

• Compressor Stations – significant emissions, higher level of regulations

• Gas Plants – lower level of emissions, most highly regulated
