## Water Definitions Used for Regulatory

Purposes with respect to Storage

Encountered Water (EW) Water encountered during oil or gas drilling operations, 

### which is of sufficient quantity to require removal, and which is not Produced Water. Frac Flow- Back Fluid (FFBF) Fluids that consist of fresh water and solids such as sand or other proppant and additives that flow from a well following hydraulic fracturing operations. Produced Water (PW) Water produced from any productive or potentially productive oil or gas producing interval in the well, which is 

### not Frac Flow
- Back Fluid or Encountered Water. 5

### Shale Water Storage Regulations based On

Regulatory Definitions of Water Type

Encountered Water (EW) May be temporarily stored in reserve pit, land application 

### by permit, removed to SWD well, or transported to centralized recycle facility. Frac Flow- Back Fluid (FFBF) May only be stored in specialized (approved) reserve pit as part of recycle/reuse system, transported to centralized recycle facility, or removed to SDW well. Produced Water (PW) May not be stored in reserve pit. Must be stored in tanks, removed to SWD well, or transported to centralized recycle 

### facility. 6

## Storage Regulatory Framework Produced Water Storage Options (if not removed for SWD well disposal) 

## : Produced water storage at well - site authorized by AOGC Rule B 26, in - ground tank storage prohibited. Produced water may be transported to an offsite “ temporary” storage as part of an approved recycling/reuse facility authorized by Arkansas Dept of Environmental Quality (ADEQ) Off- site Storage/Treatment Facilities In - ground lined pit storage authorized Permitted under NPDES or a State Authorized “ No Discharge ” 4 facilities currently permitted Governed by ADEQ Regulation 6

## Storage Regulatory Framework Frac Flow- Back Water Storage Options (if not removed for SWD well disposal) 

## : Frac Flow- Back Water storage at well - site authorized for “ temporary” storage only in portable frac tanks. Frac Flow- Back Water may be transported offsite to an recycling/reuse facility authorized by Arkansas Dept of Environmental Quality (ADEQ) OR stored on - site in a reserve pit authorized for “ temporary ” storage as part of a recycling system. On - site Storage/Re - use – Reserve Pit Primary methodology currently used Authorization by AOGC/ADEQ Joint Rule B - 17 Pit construction standards by rule Pipeline transfer system standards – BMP, welded no -joint poly Spills/discharges reported to ADEQ
