Michigan Compiled Laws, Chapter 460. Public Utilities § 460.726a

Sec. 6a. (1) The notification system shall establish reasonable procedures, including marking response times, for design ticket notification to facility owners or facility operators of requests for project design or planning services to determine the type, size, and general location of facilities during the planning and design stage of a construction or demolition project. Facility owners or operators may charge the person requesting project design or planning services separate fees for design or planning services.

(2) Procedures under this section do not affect or alter the obligation of excavators to provide notice of blasting or excavation under section 5.  1

(3) The response to a design ticket is to provide general information regarding the location of underground facilities, not to mark any facilities. However, if a facility owner or operator does not have drawings or records that show the location of a facility, the facility owner or operator shall mark that facility under the procedures described in section 7.  2 A design ticket or information provided in response to a design ticket does not satisfy the requirement under this act for excavation or blasting notice to the notification system or marking the approximate location of facilities for blasting or excavation.
