Safe Energy for Jenks

VPP Star

The Occupational Safety and Health Administration (OSHA) has awarded the Glenpool Terminal with the Voluntary Protection Programs (VPP) Star certification, signifying injury and illness rates well below the national average in their industry. To learn more about our commitment to operational excellence and sustainability, and what is required to earn a VPP Star certification, visit our VPP Star page.

What we're doing

We are committed to providing safe, clean energy to the Jenks, Oklahoma community. That's why Phillips 66 has been upgrading infrastructure at the Glenpool Terminal to enable butane blending in gasoline. Adding butane to gasoline brings the mixture up to required state and federal motor fuel volatility limits, which vary seasonally, and decreases carbon emissions. Similar facilities exist around the Tulsa area.

Committed to safety

We are committed to ensuring the safety of our employees and communities where we live and work. Glenpool Terminal in Jenks already has many safety features in place, and the new project will include additional safety features. Our plans have been approved by the State of Oklahoma, and the Jenks Planning Commission and City Council. We will continue to work with city officials and residents to ensure any remaining concerns are addressed.

Ensuring the safety of the community


Facilities that store hazardous products routinely calculate consequence scenarios to understand the possible safety concerns and then ensure the appropriate safety systems are in place to mitigate those risks.  The butane blending system is designed to meet and exceed State of Oklahoma Liquefied Petroleum Gas Administration and the National Fire Protection Association code for liquefied petroleum gas, and has many redundant safety controls, including:

  • Interlocking Emergency Shutdown (ESD) system which goes above and beyond standard safety requirements.
  • An alarm system alerts the operator(s) and area personnel, via audible and visual alarms, should any hazardous situation be suspected or identified.
  • Emergency shutdown actuators (ESDs) are installed at 8 separate system locations.
  • Atmospheric hydrocarbon detectors are placed in areas where leaks might be possible and can shut down the system if vapors are detected.
  • A grounding system ensures that proper grounding is in place between the delivery truck trailer and the offload station prior to offloading.
  • A breakaway hose and low-emission hose coupler are installed at the offload station.
  • Built-in interlocks prevent the tank from being overfilled and/or over-pressurized.
  • Pressure and thermal relief valves are installed system-wide around valves and check valves to prevent pressure build-up.
  • Fire extinguishers are located at the offload station, pump/tank area, injection skid and analyzer Enclosure.
  • Signage properly identifies all devices and operational equipment.
  • Additionally, the system uses pneumatic fail-safe valves, internal excess-flow valves on all tank inlet and outlet connections; and multiport pressure reliefs on the butane tank.
  • Blending is periodically shut down to provide maintenance, life-expectancy replacement and system-wide recalibration checks on the components.
  • Additionally, through our process hazards review process and consultation with the Jenks Fire Department, we have added remote activated fire monitors to the design which is above and beyond the regulatory requirements.
  • Phillips 66 has built and operated butane blending systems at several of its terminal facilities across the United States with no safety incidences, nor are we aware of any safety incidents involving similar facilities within our industry.
  • In the event of an incident at our facility, Phillips 66 has emergency response plans in place and regularly exercises those plans with the Jenks Fire Department.

Nothing is more important to us than ensuring the safety of the people who work at or live near our facilities. We take pride in being an industry leader in safety:

  • Our Glenpool Terminal has passed rigorous requirements to earn OSHA’s Voluntary Protection Star which recognizes employers and employees for going above and beyond industry safety requirements.  
  • We haven’t had an employee injury at this facility in almost 40 years.
  • Phillips 66 has been recognized with Safety Excellence Awards from the International Liquid Terminals Association for the past three years.
  • This facility will be regulated under OSHA PSM and EPA RMP and we put systems and procedures in place to meet those regulations.
  • Phillips 66 has a corporate Health, Safety, and Environment Management System (HSEMS) which applies to all of our business units, including Glenpool Terminal.  Key elements of the Management System are Risk Management, Asset and Operation Integrity, Emergency Preparedness, and Corrective Action Item Management.
  • Phillips 66 has a Corporate Audit Program and this facility is audited regularly to ensure compliance with regulations and company policies and procedures.
