Mechanical equipment used for routine maintenance tasks shall be defined as aerators, hand-held rototillers, soil injection needles, lawn edgers, overseeders, and hand tools.

(6.7) "Subsurface utility engineering notification" means a notice to the notification association that a project is being designed by a licensed professional engineer and that the project will include the investigation and depiction of existing underground facilities that meet or exceed the ASCE 38 standard.

(6.8) "Subsurface utility engineering-required project" means a project that meets all of the following conditions:
