CONTACT 811
Anyone planning to excavate is required to contact Miss Utility by calling 811 or visiting MissUtility.net at least three business days before work begins.
ALLOW REQUIRED TIME FOR MARKING
You need to wait three business days in Maryland for utility locators to have an opportunity to mark the location of utility lines with flags or a special spray paint.
RESPECT THE MARKS
In Maryland, the tolerance zone is defined as the width of the utility line plus 18 inches on each side. Do not use power digging equipment within the tolerance zone.
EXCAVATE CAREFULLY
State law requires that you hand dig or use other nonmechanical means within the tolerance zone.
Remember: Never assume pipeline location or depth. Locating procedures do not verify depth of main. Erosion, weather conditions, terrain modifications and previous digging projects can alter the landscape and bring pipelines closer to the surface.
