• Site specific review and permitting process required.
• Injection zone strata must be evaluated for ability to accept and retain injected fluid.
• Injection fluid/strata water quality must be fully characterized.
• Regulated by NYSDEC Division of Mineral Resources and USEPA (Underground Injection Control Permit)
On-site treatment systems can reduce sodium chloride and TDS levels. These will be operated by gas development company.
