Air Quality Monitoring

Upwind and downwind air quality monitoring equipment measuring PM2.5 (particulate matter) and VOCs known as BTEX was installed within 500’ of the well pad by a qualified third party, Clean Air Engineering.

The prevailing wind direction for this region is from the southwest. Clean Air Engineering positioned the PM2.5 monitors such that one would be subject to winds from upwind of the well pad and the other would be in the path of wind traveling across the well pad (downwind).

Due to the pre-existing monitoring configuration and constraints of the property (airport security restrictions) near the ACAA 4 Well Pad, standard spacing considerations for the placement of BAM monitors—ideally sited at a minimum distance of 500 feet—were not achievable. As a result, the location of the monitor placed in the prevailing upwind location may influence data interpretation due to its proximity to development activities, and users should consider this constraint when evaluating the measurements presented.

Prior to drilling and hydraulic fracturing operations on site, the chemical additives proposed for use are posted below. After operations are complete, the final disclosures are posted.

The Radical Transparency program includes monitoring of well pads in the construction, drilling, and completions phases of development through approximately 6 months of production. The first phase of air monitoring for this site was archived under the Radical Transparency program. Data from the archived, first phase is shown below.
