Challenge

An oil and gas client required decontamination of 10,295-square-feet of its industrial administrative offices at a natural-gas processing plant after an employee tested positive for COVID-19. The facility was located in a remote area in Wyoming that was experiencing adverse weather conditions of snow and flooding, causing widespread road closures.

A land-development company hired GES to inspect streams and their banks in areas difficult to access on foot. GES pilots created and modified multiple flight paths, flying at various elevations (100 ft., 200 ft., and 400 ft.) and in different patterns, to capture high-definition photos and videos, as well as data from beneath the dense tree canopy. The collected data was processed using DroneDeploy and ArcGIS software to create orthomosaic and topographic maps that were used to analyze stream and bank conditions and aid in ongoing stream redesign and mitigation efforts.

GES provided air compliance support by first identifying a methodology to demonstrate compliance with a longstanding, prohibitory rule. GES’ effort required regulatory knowledge and reconnaissance of the specific intent of the rule prior to preparing the compliance statement. The Title V permit was reviewed jointly by the local air-permitting agency and US EPA. GES’ regulatory expertise aided in ensuring air compliance and allowed for successful preparation of the required permit.
