Hazard Zone

Williams is not required by law to notify those residents who live in the Hazard Zone of the Atlantic Sunrise pipeline, but we thought you'd like to know.

We oppose the pipeline because its benefits to Lancaster are negligible compared to the damage it will cause; because it is a money-saving "shortcut" for Williams, redundant to other existing lines; because we are Lancastrians who value our clean water, soil, and air; and because the project usurps private and public property for corporate profit. We believe that Williams's methods and practices have not been properly scrutinized, essentially that they have bought the regulatory bodies and courts that have permitted this project to continue, and that this project endangers our property and rights.

We've provided a map, below, which you can use to identify where the hazard zone crosses your property, but we suggest you contact FERC to confirm.

We urge you to be aware of the dangers of this project--and to join us in the movement to stop its construction.

What is the Hazard Zone?

The Atlantic Sunrise is a natural gas line that "moves flammable gas under extreme pressure, creating a risk of pipeline rupture and potential explosion. The 'potential impact radius' or 'hazard zone' is the approximate area within which there will be immediate damage in the case of an explosion. Should this occur, everything within the hazard zone would be incinerated and there would be virtually no chance of escape or survival." (Source, see also FERC.gov)

How is it calculated?

Based on the Atlantic Sunrise pipeline's diameter and pressure, the hazard zone can be calculated using the formula: potential impact radius = 0.69 * pipeline diameter * (√max pressure ).

Based on this formula, the hazard zone for the Atlantic Sunrise, with its diameter of 42 inches and maximum pressure of 1480 psi, is 1,115 feet (340 meters) on either side. That's the equivalent of more than 3.5 football fields on either side of the line.

If you live in this area, you should be aware of the dangers to your family and property.
