Underground Marking Standards
Marking Standards & White Lining
On October 20th, 2007, Georgia Public Service Commission Rule 515-9-4-.14, entitled
Georgia Underground Utility Marking Standards, went into effect. The first section of the rule describes white lining.
The Georgia Underground Facility Protection Act (GUFPA) states that if the location for the blasting or excavation cannot be defined with sufficient particularity, the person doing the blasting or excavating needs to white line the area where that work is to be done. (For official wording, see 25-9-6 B.) Section 1d of the commission rule is a directive to the Utilities Protection Center, d/b/a Georgia 811 to establish policies and procedures which determine sufficient particularity and identify when white lining is required.

As of January 1, 2008, excavators should have been proficient in the rule regarding white lining and should have applied this rule to current marking procedures.
