Underground Damage Prevention Program

Maine Law Requires Anyone Using Power Tools to Penetrate the Ground (Including Homeowners) to First:

  1. Pre-mark the boundaries of the proposed area of excavation with white markings.

  2. Call 811 three (3) business days (72 hours) prior to digging.  Dig Safe® will then automatically notify all of its member utilities that own underground facilities in the area of the excavation so that they can mark their facilities.

  3. Notify all non-member owners of underground facilities in the area of the excavation 3 business days prior to digging as some underground facilities may be private.

The Maine Public Utilities Commission (MPUC) is vigorously enforcing these rules and may fine you up to $5,000 per violation if you do not comply.  Therefore, please take time to review and understand the law (Title 23, §3360-A) and the MPUC Rules (Word).
