We have installed emission reduction devices on our compressors, and, where practical, our loading and storage tanks and other equipment, and we use BTEX controllers on our dehydration units to reduce air pollutants. We make every effort to put the well in line and close pits promptly after completion so that we can further reduce emissions from the well site.
Regulations in the states in which we operate establish emissions limits, emissions control requirements, monitoring and test requirements and report requirements to protect and maintain air quality. We operate in compliance with applicable regulations and, in many cases, we exceed them.
Where infrastructure is in place, we use pipelines for the transportation of production to reduce transportation emissions.
Solid Waste and Sludge Residuals
It is our policy to dispose of drill cuttings and other solid waste and sludge only in licensed disposal facilities.
We also monitor and track NORM (naturally occurring radioactive materials) in our waste streams and, if necessary, we treat it and dispose of it properly at licensed facilities.
After completing the well, we retain a certified third party laboratory to collect and analyze water samples from the same water sources we collected from prior to drilling. We have not had any negative outcomes when comparing pre-drilling and post-completion water samples. We share the post-completion water testing results with the landowner once we receive them.
We install liners under, and metal firewalls around, oil tank batteries to insure the containment of any spills.
End of the Life of the Well
Approximately one year after the well starts producing, the well site is reclaimed and the size of the disturbed land necessary to produce the well is significantly reduced.
After the well has ceased producing, we plug the well in accordance with local regulations and take care to restore the land to leave it as close to the way we found it as is reasonably possible.
In the event we drilled a water-well for use in our operations, we offer the well to landowners for their personal use.
Our operations are handled by trained personnel, and we routinely conduct on-site safety reviews to ensure compliance with best practices. We have also adopted, in accordance with local regulation, emergency response plans so that we are prepared to respond quickly and effectively in the unlikely event of an unplanned incident.
Our contractors are routinely audited:
- Before they can commence our work, our Environmental, Health and Safety group audits our contractors to ensure the adequacy of their environmental, health and safety training;
- If we find their training is deficient, we require them to attend our training sessions;
- We require our contractors to register on ISN (www.isnetworld.com) which collects safety, sustainability, quality and regulatory information and verifies its accuracy; and
- In addition, in 2012, our outside independent internal auditing firm completed a specific environmental, health and safety audit.
