AIR LIQUIDE ADVANCED TECHNOLOGIES US LLC (WINNEBAGO PIPELINE), located at 8554 Lindenwood Road, Rockford, IL 61109, owns and operates a non-odorized natural gas transmission pipeline system in your area. Yellow vertical pipeline markers with our name indicate the approximate location and route of our pipelines. AIR LIQUIDE maintains and operates a Damage Prevention and Public Awareness Program for its operations of this pipeline system. Keeping the public, the environment, and our pipeline safe with valuable experience, sound judgement and by following federal codes is our top priority. The pipeline is reliable and no underground leaks have been detected. We use preventative measures such as routine patrols and leak surveys to keep the pipeline safe. A copy of this plan is available in our office. This program includes educating and notifying the residents about specific operations requirements and the existence of the program. These requirements include: 1. Contact AIR LIQUIDE if you plan to excavate and/or blast on or within two hundred (200) feet of our pipeline right-of-way. Company personnel will locate the pipeline for you to ensure safe excavation and/or blasting. All excavators must use Illinois 811 (J.U.L.I.E) program prior to digging. 2. Contact and/or advise others who you believe to be working near our pipeline to contact AIR LIQUIDE before performing any activity that might damage our pipeline system. 3. Be aware of gas leaks and hazards and report them immediately. Signs of gas leaks include the hissing sound of escaping gas, dead vegetation, blowing earth, bubbling water, and the smell of gas. Note that the gas in the AIR LIQUIDE pipeline does not contain artificial/added odorant so the odor of gas may not be present though a leak may exist. Emergencies include any gas leaks, fire or explosion, natural disasters or civil disobedience. If you suspect that the pipeline is leaking, stay away from the area, have others stay away from the area, and notify the company immediately. In case of fire/explosion or natural disaster near the pipeline, notify the company immediately. If you smell gas inside, get out immediately. If you suspect a leak outside, turn off and abandon any motorized equipment you might be using. Leave the area quickly. Gas is an asphyxiant and can be deadly since it displaces oxygen. By notifying AIR LIQUIDE immediately upon any of the above incidents, the appropriate responders will be dispatched promptly and effectively to take care of the emergency. 4. Do not attempt to locate the gas leak with matches or other open flames. Do not remain in a building if there is a strong odor. Do not turn lights on or off or unplug electrical appliances where there is a strong odor. Do not use a telephone in the area of a strong gas odor. Don't use anything that would spark ignition such as cell phones, flashlights, motor vehicles, power tools, electrical equipment, etc. To help us enforce our Damage Prevention and Public Awareness Program and ensure the safe operation of our pipeline system, please call these numbers to report excavation projects or suspected gas leaks: Day time #: 224-347-3985 24 Hour Emergency: 800-364-7378 *Identify your call as an AIR LIQUIDE (WINNEBAGO PIPELINE) Emergency, Rockford, Illinois Rockford Police: 911 Rockford Fire & Ambulance: 911 Log on to the PHMSA.dot.gov website for additional information.
