Any time an excavation is being done within 25 feet of our pipe, a representative from SDIP will be on site. This is for the safety of the excavator, as well as the integrity of the pipeline.

Natural gas is lighter than air, colorless and odorless.
At SDIP, we inject an odorizing agent to the gas we transport.
This chemical gives the gas a “rotten egg” odor, and makes the gas readily detectable.

24. Emergency Procedures
If you should detect the odor of rotten eggs in the vicinity of the pipeline, we would ask that you take the following actions:
Remove any sources of ignition (no smoking, matches or open lights)
Move to a safe area
Call our Toll-Free Emergency Number
