The facility operator/locator should communicate the delay with the excavator through an email, phone call, or both. The facility operator/locator may additionally post information on our Electronic Positive Response (EPR) system. Currently, participation in EPR is voluntary. To check the responses for your requests, go to: https://www.bluestakes.org/epr/. This is also accessible by clicking on the Positive Response icon or EPR Lookup icon from within our Mobile App.
