Antero’s produced and flowback water is stored in temporary and permanent tanks on producing well pads. Most water is taken directly to treatment or disposal. To mitigate spills and leaks all storage tanks on producing well pads are located within secondary containment and the perimeter of the well pads have an earthen berm to prevent materials from migrating offsite acting as tertiary containment.
Antero also has a limited number of centralized wastewater pits that were designed and built to robust regulatory standards including utilization of a dual liner design. Additionally, all centralized wastewater pits have a leak detection layer within the dual liner system, groundwater monitoring wells which are sampled quarterly for a list of parameters beyond which is required by regulations and a concrete containment with offload manifold to facilitate truck offloading.To reduce hazards to wildlife, all centralized wastewater pits have fencing and bird netting installed in compliance with the North American Migratory Bird Treaty Act (NAMBTA).
Other facilities that generate or receive liquids (ex. compressor stations) utilize closed top tanks and employ secondary containment and perimeter berms to manage liquids onsite and reduce potential impacts to the environment and wildlife.
Emissions from all sources are calculated and reported as required by state and federal laws and regulations.

Antero does not currently utilize residuals or waste products from the company’s operations for purposes other than hydraulic fracture stimulation and brine generation for downhole use.
Antero does not dispose of our wastewater or flowback from fracture stimulations by discharging to the surface or waterways. All of Antero’s wastewater is either treated for re-use downhole, sent for disposal via underground injection wells, or sent for solidification and offsite disposal, and thereby minimizes exposure to human and environmental receptors.
Hydrocarbons are recovered to the extent feasible and sent to a used oil recycler for processing and reuse (e.g. fuel oils, heat recovery, etc.). Additional details of the oil recycling program can be found in our waste summary section.
