• On-Site/Off-site Treatment and Discharge
– 2010 revised regulations required publicly owned treatment works and centralized waste treatment facilities to treat new or increased discharges of Total Dissolved Solids (TDS) to more stringent standards.
– Practice of treatment and discharge of unconventional wastewater voluntarily discontinued in April of 2011.
Wastewater Management Options - Discharge
8
• Reuse without Processing
– Permitted Well Site; or
– Off-Site Permitted Well Site
– Managed, transported and stored as a waste
– If stored off the well site, considered to be a transfer station requiring a permit
• Since 2010, wastewater reuse has increased from 2.6 to over 22 million bbl/yr.
Wastewater Management Options - Reuse
9
• Processing Prior to Beneficial Use – On a permitted well site approved by the Oil and Gas
Management Program • Managed, transported and stored as a waste
– Off Well Site • GP 123
• Individual waste permit
• Managed, transported and stored as a waste
– Since 2010, wastewater recycling has increased from 4.6 to over 7.8 million bbl/yr.
Wastewater Management Options - Recycling
10
• Processing and beneficial use of processed liquid wastes
generated by oil and gas well sites and associated infrastructure.
• Encourages the return of treated liquid waste to oil and gas well sites for reuse.
• Wastes include drilling fluid waste, hydraulic fracturing fluid waste and produced fluid.
• Minimizes water withdrawal and emission impacts on valuable water resources.
• Solids generated through treatment are processed for disposal in a landfill.
Processing Wastewater for Beneficial Use
General Permit WMGR123/Individual Permit:
11
• Administered by US EPA
• Eight permitted underground injection wells in Pennsylvania

• Form U Disposal Approval for PA Landfills
– Must meet Landfill Acceptance Criteria
– Submitted to DEP Regional Offices
• In 2012, the total amount of solid waste generated by the oil and gas industry and disposed of in Pennsylvania landfills was 1.3 million tons.
