Each year, the Missouri Attorney General’s office takes action on member utilities and excavators who fail to comply with the Missouri Underground Facility Safety and Damage Prevention Act, RSMo Chapter 319.010-319.050.

Enforcement of the Underground Damage Prevention law results in penalties and warning letters issued to member utilities and excavators by the AG’s office.

If you feel there has been a violation to Chapter 319 be sure to document as much of the incident as possible such as date, time, address, name of company, person or persons involved, etc. If possible, take photographs of the incident.

Violation letter templates have been created for you to use to report a violation. Feel free to download the appropriate violation letter for your company to use. Click here to go to the violation letters.
