What to look for in the Technology?
The equipment
▪ Low Emissions ▪ Reliable ▪ Efficient ▪ Cost Effective ▪ Small footprint
Market Focus:
▪ Produced water from oil and gas exploration and production ▪ Water from gas midstreamers (pipelines, compression) ▪ Other Applications: industrial wastewater such as cooling process blowdown or process waste (e.g., mining or power generation)

Mobilization: What should the provider handle?
It is optimal where the provider of the equipment takes complete responsibility for the successful, safe, and reliable operation of their unit, by doing the following: Handle the air permitting process (if any) in cooperation with producer’s permit and environmental staff A performance and quality check prior to the unit being shipped, including: – A 24-hour factory acceptance test, verifying evaporation rates, gas requirements, control sequences and start up/shutdown Plan, manage and execute all aspects of transportation, installation, commissioning and start-up Provide secondary containment for all units on customer’s pad Provide complete on-site operational support and maintenance for the unit

Mobilization: What Does the Customer Handle?
Site or customer specific HSE instructions/guidance/permits – Customer permits (OG 71/71a, WMGR 123) – Policies and procedures for safe and responsible operations – Equipment siting criteria (e.g., spacing from existing operations) – Operations and HSE emergency contacts – Police, fire and EMS contacts Site modifications to support evaporation which typically include: – Produced water and brine connection lines – Gas service to the unit – Access to pad – Produced water and brine storage Removal of concentrated brine – Pipeline – Truck

Permitting Process
If the equipment meets the annual particulate emissions (PM) under the 3 ton/year threshold, and a burner consuming less than 2.5 Mbtu/hr a unit should be able to be put in service quickly On Pad Processing ▪ Construction: RFD issued by Air Quality Department Regional Office based on GP-5A Category 38 exemption and completion of the standard RFD application with required supporting exhibits ▪ OG 71: Request for Approval of Alternative Waste Management Practices: captive processing of wastewater
Operations are subject to permit conditions including ongoing monitoring and
record keeping as established by DEP
Off Pad Processing
▪ Waste Permit: Individual Processing Permit (facility) ▪ Construction: RFD, (ideally unit should be exempt from Plan Approval)

What does Evaporation Technology offer?
Evaporation Technology Offers Customers: ▪ Immediate reduction in wastewater transportation and disposal costs ▪ Zero customer CAPEX based on pay for performance model ▪ Streamlined permitting based if meet exemption emissions ▪ Small footprint minimizes on-pad operations impact ▪ Modular design allows scaling to meet demand, rapid mobilization and easy redeployment ▪ Positive net benefits in environmental (emissions), safety, and community relations (reduced truck traffic)
