  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.
• Once the pipeline is exposed, the pipe and
  coating are inspected for damage or signs of
  corrosion.

22

• The SDIP representative will remain on site until
  the pipeline is once again covered.

23
Emergency Procedures

• 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

25
Emergency Procedures

• In the unlikely event of a pipeline leak, you may
  hear a hissing noise, or a loud wind sound,
  accompanied by the odor of rotten eggs. Again,
  follow the afore mentioned procedures, and do the
  following
• 1) Evacuate the area in a 200 yard radius from
  the point of the incident.

26
Emergency Procedures

• 2) Remove ALL sources of ignition (no smoking,
  turn off motor vehicles,) from the evacuated
  area.
• 3) Contact SDIP IMMEDIATELY.
• 4) DO NOT attempt to contain the leak, or operate
  any SDIP equipment.

27
Emergency Procedures
