How did OAQPS get involved?Region 8 requested OAQPS assistance with understanding the VOC emissions from the upstream oil and gas production due to public concern and ozone exceedencesEmissions sources and activities for this sector are extremely difficult to measure due to the complex nature, quantity and varietyAlmost no VOC data exists for this sector from actual field testing
