The oil and gas industry is adopting technologies for cleaner generators and the application of emission controls on diesel engines. Members of the industry are also switching from diesel engines to engines that operate on cleaner natural gas.
Potential Near-Source Ozone Impacts of Oil and Gas Sites in the Eagle Ford Shale
With financial support from the Environmental Defense Fund, Dr. Eduardo (Jay) Olaguer used the HARC microscale air quality model to assess the ozone impacts of oil and gas production facilities in the Eagle Ford Shale. Different geographical configurations and ozone transport conditions were used to gauge how much oil and gas sites may increase ambient ozone over regional background levels. A unique aspect of the assessment was the application of the model inverse mode and automated gas chromatograph measurements to determine the composition of suspected flare event emissions. Primary formaldehyde (HCHO) and reactive hydrocarbons from combustion sources were found to increase peak ambient ozone within the study area in Karnes County, Texas by up to ~4 ppb. Moreover, flare event emissions increased exports of odd oxygen (O3 + NO2) at the model edge by up to ~12 ppb. Carcinogenic species were also significantly enhanced; HCHO concentrations over 10 ppb and benzene concentrations over 50 ppb were produced within 10 km and 500 m respectively downwind of the flare event source.
The City of Houston recently announced its Climate Action Plan that will bring together stakeholders from across the community to develop a variety of cost-effective energy efficiency, renewable energy and
In 2015 HARC completed a project that identified the primary sources of fine particulate matter or PM2.5 pollutants in Harris County as well as the control measures that can be used to reduce them. Each control measure has a unique efficiency and cost.
HARC is working with the Environmental Defense Fund (EDF) to identify inexpensive methane sensors that can be deployed in a variety of oil and gas operations to rapidly identify and facilitate repair of natural gas leaks.
