**This declaration will only be made through Positive Response, which is a code 110. **

Extraordinary Circumstances

The South Carolina Underground Damage Prevention Act states, ‘Extraordinary Circumstances’ means circumstances which make it impractical or impossible for the operator to comply with the provisions of this chapter. Extraordinary circumstances may include hurricanes, tornadoes, floods, ice, snow, and acts of God.

If an operator declares extraordinary circumstances and is unable to locate the area within the required time period, they will respond with a 110 code in the positive response system.  The below graphic references the information required to enter a 110 PR Code (Extraordinary Circumstances).

The operator must state in the remarks what type of event is taking place, as well as the date and time when the location will be marked. An excavator is required to check positive response before excavating. If a 110 code is used the excavator must not excavate or demolish until after the time and date that the operator provided in its response.

If a member operator has catastrophic event and is unable to respond due to power failures or other unforeseen conditions they can contact SC811 for assistance.

****If you are entering a new or subsequent action locate request after 9/10/18 PLEASE READ****

As Hurricane Florence approaches, many coastal areas in South Carolina have been ordered with a mandatory evacuation. As a result, excavators entering action notices may see areas on the map represented in a pink color when plotting their excavation site. Please keep in mind that notices in these areas are likely to receive a Positive Response 110 code for ‘Extraordinary Circumstances’.

What Does This Mean?

There will be no access to many of those areas for locators to mark facilities. Please consider postponing your work until after the storm. Locators should reference a remark date for when they will be able to locate if excavators choose to proceed. SC811 will update https://sc811.com/extraordinary-circumstance-declarations/ as we identify any members utilizing the 110 code with their member number.

Thank you all for your patience, and we hope that you and your loved ones stay safe during Hurricane Florence.
