NYSEG is reminding contractors and customers working on projects at home that every excavation project, no matter how large or small, always requires a call to 811. Every year, there are dozens of incidents involving third-party damage of NYSEG’s underground natural gas and electric facilities. These incidents can put people’s lives in danger, are costly and can interrupt essential utility service. 811 should be called at least two working days and no more than 10 working days before excavation work begins.
