Keep your natural gas appliances and/or equipment in good working condition by following these safety tips:
When dealing with a sewer blockage, there is a remote, yet potentially hazardous condition that could be created when dealing with a sewer blockage.
Directional Boring and Cross Bores
Utilities use a trenchless technology called horizontal directional drilling (or directional boring) to pull cables, conduit and pipe underground. This installation method causes minimal impact to the surrounding area and minimizes environmental disruption. It also saves time, allowing utility crews to work more efficiently. There are instances when an underground sewer line is not properly identified prior to directional boring activities and it’s possible that a natural gas pipe can be inadvertently pulled through a sewer line. The resulting condition is known as a “cross bore.” Cross bores can go unnoticed for months or even years. They are typically discovered when it becomes necessary to clear a sewer line blockage.
If a natural gas pipe has been bored through the sewer line, the gas pipeline could be damaged, resulting in a loss of service and a potentially hazardous leak condition. If you are aware of the existence of a cross bore, call Chattanooga Gas at 866.643.4170 and report it as a natural gas emergency.
Chattanooga Gas is committed to maintaining a safe and reliable natural gas pipeline infrastructure that serves the needs of its customers. We are committed to maintaining a safe and reliable natural gas pipeline infrastructure that serves the needs of customers, including emergency preparedness.
We work closely with local/regional emergency response officials located near our pipeline facilities to ensure a better understanding of the nature of our infrastructure and our emergency preparedness plans.
For Government and Emergency Response Officials
The National Pipeline Mapping System provides a list of pipeline operators within a specific county or ZIP code, including the appropriate contact information.
The federal Office of Pipeline Safety has developed the Pipeline Integrity Management Mapping Application (PIMMA) for use by pipeline operators and federal, state and local government officials. PIMMA is intended to be used solely by the person who is given access by the Office of Pipeline Safety.
Anyone wishing to use PIMMA should contact the Office of Pipeline Safety directly to obtain access. The Office of Pipeline Safety monitors user activity and reserves the right to remove individual access rights.
Safety is our number one value. That’s why we go beyond state and federal requirements when it comes to educating the public and our customers about:
We carefully maintain a network of natural gas mains and service pipelines that deliver safe and reliable natural gas to the communities we serve.
