TERC Project H13 has drawn attention to the importance of emission events of highly reactive VOCs (HRVOCs) in explaining the occurrence of rapid ozone formation and transient high ozone events (THOEs) in the Houston region. Emission events can occur during industrial process maintenance, start-ups and shutdowns, or from upsets. They may be associated with fugitive emissions points and emissions points associated with flares, cooling towers, and process vents.

Emission events occur most often in Houston and Brazoria counties at chemical manufacturing facilities, with ethene and propene being the dominant compounds released during the events. Control of HRVOCs from emission events may be an important strategy for ozone attainment. Causes of emission events are numerous and vary from emission event to emission event. This project looks at ways to control HRVOC event emissions by studying the co-benefits of reducing HRVOC’s (which also reduce other VOC’s), the impact of a HRVOC cap and trade program, and the possible adoption of other regulatory strategies (foreign and domestic) to control VOC's.
