Gulf Coast Pipeline

Use caution in the event of a suspected pipeline leak or in the event of any of the following suspicious conditions:

Sight:

• Some gaseous and most liquid leaks or releases may be visually detectable. A dense white cloud or fog originating near a pipeline marker, vent or above-ground equipment may be the result of a leak. Extra caution should be used to avoid ignition as  such fumes and mists are likely flammable.
• Dust blowing from a hole in the ground
• Dead or discolored vegetation in an otherwise green area
• Continuous bubbling in wet or flooded areas
• Flames, if a release has ignited
• Large ice ball formation on above-ground piping

Sound:

• You cannot always see that there is a pipeline leak. Diamond Infrastructure Solutions transports a variety of products, some of which may not be detectable by sight should a leak occur. However, hearing a hissing or blowing sound may identify a release depending on the size of the release

Smell:

• Products escaping from a pipeline may sometimes be detected by a gas or "smelly oil" odor

The vast majority of products Diamond transports are hydrocarbon based products which means that they will ignite and burn if released and exposed to an ignition source.

Even though pipelines are the safest means of transporting products, according to the U.S. Department of Transportation, system leaks do occasionally occur. Leaks are most often caused by damage from digging near a pipeline. Here are a few ways in which you may get involved and help keep pipelines, underground utilities and our communities safe:

• Before you dig, drill or blast near a pipeline, call 811 to get the exact location of any pipeline or underground utility. Let pipeline or utility operators show you where the pipeline or underground utility is located. It's free and it's the law.
• Using specialized locating equipment, pipeline or utility operators can locate the pipeline or underground utility and determine the depth without disturbing the earth.
• Never try to locate a pipeline or underground utility with a backhoe, bulldozer, auger, pick or any other piece of equipment. These are dangerous substitutes for specialized locating equipment.
• Although pipelines are patrolled, your diligence is also essential for keeping them safe.
• Even seemingly minor damage must be immediately reported to the pipeline operator. A gouge, scrape, dent, crease or other damage to a pipe or to the pipe’s coating may one day result in a break or leak. It is very important that the pipeline operator evaluate the situation and, if necessary, repair any damage to the pipeline as quickly as possible. 
• Report suspicious and unauthorized activities on and near Diamond's pipeline right-of-ways and give us a call if you see something out of the ordinary.
• One simple phone call to 811 may prevent a pipeline or underground utility accident from occurring.  Before you begin digging, please call 811 or your local State One Call Center 48 hours in advance to get a location of pipelines and underground utilities in your area. Pipeline and utility representatives will come to your location and mark their lines for free.
  
  Before you dig, call 811, or contact your local State One Call Center directly.
