Michigan Gas Safety Standards Revised

The 23rd edition of the safety rules, or standards, took effect December 23, 2014.

On July 15, 2013, the Commission sought permission from the Office of Regulatory Reinvention (ORR) to revise rules governing gas pipeline safety to incorporate updated federal standards into the Michigan rules. ORR approved the request for rulemaking and assisgned ORR #2013-070LR on August 7, 2013. The Commission submitted the draft rules to ORR and the Legislative Service Bureau (LSB) for informal approvals, which were granted on February 10, and March 10, 2014, respectively.

On June 19, 2014, the Commission issued an order providing the public with an opportunity to comment on the proposed revisions. See MPSC case docket number U-17462. The Commission held a public hearing on July 17, 2014, at which one person testified. The Commission also received three written comments. On October 16, 2014, the Commission issued an order approving revised rules and submitted them to LSB and ORR for their formal approvals, which they granted on December 2, and December 3, 2014, respectively. On December 3, 2014, the rules were filed with the Joint Committee on Administrative Rules (JCAR), which, by virtue of MCL 24.245a(1), had 15 session days to object to the rules by filing a notice of objection. On December 17, 2014, JCAR waived the remaining session days for rule review.

On December 18, 2014, the Michigan Public Service Commission issued an order formally adopting the proposed rules and transmitted the adopted rules to ORR for filing. The rules were filed with the Office of the Great Seal on December 23, 2014.

Prior to year 2000, the Michigan Gas Safety Standards were referred to as the Michigan Gas Safety Code and appeared under R 460.14001 to R 460.14999 of the Michigan Administrative Code. Starting on January 6, 2000, the Michigan Gas Safety Standards replaced them and appear instead at R 460.20101 - R 460.20606 of the Michigan Administrative Code.

Call 811 before you Dig

Homeowners often make risky assumptions about whether or not they should get their utility lines marked, but every digging job requires a call even small projects like planting trees and shrubs. The depth of utility lines varies and there may be multiple utility lines in a common area. Digging without calling can disrupt service to an entire neighborhood, harm you and those around you and potentially result in fines and repair costs. Calling 811 before every digging job gets your underground utility lines marked for free and helps prevent undesired consequences.
