· Properly drilling, completing, operating, and P&A to ensure and maintain isolation of productive zones from GW & SW.
· Properly storing, treating, reusing/recycling, transporting, and disposing of wastes.
· Properly installing and maintaining associated equipment & E&P waste management facilities.
· Rapid response to and thorough remediation of impacts from spills and releases.
GROUND WATER PROTECTION
· Collect samples from water wells, soil or other media for field and laboratory analyses.
· Collect samples of gas, oil, condensate, produced water, flow back, or other wastes from nearby oil and gas wells.
· Compare analytical results to background and water regional water quality.
· Compare stable isotopic signatures and composition of gas samples to determine source.
· If we verify a complaint:
· Operator must remediate impacts to meet standards.
· Operator must mitigate impacts.
