Protecting Our People, Partners & Environment

Nothing is more important than the safety of our employees and the communities and environments where we operate. Chaparral’s unwavering focus to make safety our number one priority is why we require ongoing training and certification for everyone who sets foot on our locations — employees, vendors and contractors alike. It’s why we never stop looking for opportunities to decrease our environmental footprint. And it’s why we’ve become a best-in-class safety operator.

Our goal is simple — safely and efficiently produce the resources needed to propel our company, partners and local communities forward.


Chaparral teams with ISNetworld to implement an enhanced screening and requirement process to ensure our vendors follow the necessary processes and safety procedures. These extensive efforts ensure not only the safety of our employees and facilities, but also that of the contractors working on our locations and the communities that surround them.

Pipeline Safety

Underground pipeline systems are the most efficient and safest way to transport vital oil and natural gas across the U.S. Often unseen avenues, people living and working near pipelines are not always aware of common safety practices. It is important for everyone to be familiar with the location of the pipeline, recognize and report any unauthorized activity or abnormal conditions and know how to safely react in the unlikely event of a pipeline emergency.

Chaparral operates more than 171 miles of oil, natural gas and CO2 pipelines in Oklahoma, Texas and Kansas. We monitor our pipelines 24-hours-a-day, 365-days-a-year to ensure the safety and integrity of our operations. In addition, we treat corrosion threats and conduct regular patrols and inspections of our pipelines and related rights-of-way (ROWs) to ensure the safety of our employees, neighbors and the environment. 

Pipeline Markers

Markers and warning signs are placed aboveground to indicate the general location of pipelines buried beneath the surface. This includes near river, railroad and street crossings and other heavily congested areas. These markers do not, however, show the exact location, depth, pressure or number of pipelines. You should also remember that pipelines do not always follow a straight path.

Yellow flags are used to temporarily mark the general location of a pipeline in a proposed excavation area. Be familiar with permanent markers and the information they contain including the: 

  • Material transported in the pipeline
  • Name of the pipeline operator
  • Telephone number where the operator can be reached in an emergency

Call Before You Dig

an image of Call Before You Dig

Call 811 at least 48 hours prior to digging or excavating.

It is important to dig with CARE as damage from excavation-related activities is the leading cause of pipeline incidents.

By law you are required to call 811 at least 48 hours prior to performing any excavation or logging activities. This includes starting home projects, such as building a pool or fence, widening a driveway or planting a tree. If Chaparral operates pipeline in the vicinity, we will be notified and will locate and mark our pipeline with temporary flags or spray paint before you dig at no cost to you.


Call Before You Dig

Use white paint, flags or stakes to mark intended dig sites and then dial 811 to contact the state’s one-call center.

Allow Time for Marking

Wait the required time before beginning any excavation activities. Marks should be made using the colors indicated by the American Public Works Association Uniform Color Code.

Respect the Marks

Verify the location of marked facilities and check for unmarked facilities before digging. A photograph of the marks should be taken before excavation begins.


Excavate Carefully

When excavating in the tolerance zone — 18” - 24” on each side of the marked facility — only use non-invasive methods, such as hand digging or vacuum excavation. An observer should be designated to watch for potential dangers or damages when digging around a pipeline.

Recognizing a Leak

Use Your Senses

Although pipeline leaks are uncommon, it is important to be able to recognize the warning signs. Sight, smell and sound are the common ways to recognize a possible pipeline leak. You should, however, remember that not all of these signs may occur at the same time.

Look For

  • Discolored or dead vegetation
  • Flames coming from the ground
  • A cloud of vapor, fog or mist
  • A pool of liquid on the ground or bubbling in a wet, flooded area
  • Dirt blowing in the air
  • A rainbow or sheen on the water

Smell For

The scent of gas, petroleum or an unusual odor, such as rotten eggs

Listen For

An unusual hissing or roaring noise 

If A Leak Occurs:an image of If A Leak Occurs:

  • Turn off and abandon any motorized equipment.
  • Evacuate the area quickly and cautiously by walking into the wind, away from possibly hazardous fumes.
  • Warn others to clear the area.
  • Call 911, your local fire or police department and the pipeline operator (or 811 if operator is not known) once you have reached a safe location. 
  • Do not touch, inhale or make contact with leaking liquids or gas.
  • Do not use open flames or anything that could ignite a spark (cell phones, flashlights, motor vehicles, tools, etc.).
  • Do not attempt to extinguish a natural gas fire.
  • Do not attempt to operate pipeline valves. Wait for an authorized representative from the pipeline operator.

Pipeline Encroachments

A right-of-way (ROW) is a defined clearing above and on either side of a pipeline. It is typically identified by pipeline marker signs and allows operators access to conduct regular inspections and in the event of an emergency. An encroachment is a structure or object that overlaps the ROW that might impede access or pose a significant risk to the pipeline and should not be installed without permission from the pipeline company. Examples include:

  • Buildings or structures
  • Decks 
  • Fences
  • Other pipelines
  • Parking lots
  • Ponds
  • Residential encroachments
  • Roads
  • Sheds
  • Sidewalks
  • Swimming pools
  • Trees
  • Utility lines
