Minutes of The Marking Guidelines Meeting
September 26, 2006
Miss Utility Call Center
Hanover, MD 21076

Wayne opened the meeting with introductions.

The Meeting Minutes from the August 22, 2006 meeting were reviewed and accepted. Contact information was corrected and verified.

Definition change: We are all in agreement of the marking for visual perimeter of a facility shall be a solid line and the facility owners can establish the size of the Safe Hand dig Zone. The recommended title is Perimeter Markings of Structures / Hand Dig Zone. A definition should be included. Visual facility structures that are on or beneath the surface, examples included but not limited to are manholes, underground tanks, poles, communication pedestals, gas and electric structures, vaults, water and sewer facilities, etc. While working in the proximity of an identified underground structure, it is incumbent upon it is the responsibility of the excavator to positively identify the outermost edges of the structure by hand or by vacuum excavation equipment or call the facility owner for assistance. Tim Kempa recommended the following: In referencing below ground structures, the structure will be identified by a minimum of a 3x3 box with arrows extending from each corner, see fig. 1-1. Regarding above ground structures, perimeter size is to be established by the utility owner. Within any established perimeter, identification of the outermost edges shall be determined by hand or vacuum excavation.
