**body:**

Upon application by an operator, the MPUC may grant a waiver from
compliance with the federal gas pipeline safety regulations for
intrastate pipeline transportation, subject to review by PHMSA.

  A. The MPUC may grant waivers for particular circumstances where it is
  inappropriate for an operator to follow a regulation of general
  applicability.

  B. Before granting a waiver, the MPUC must give notice and opportunity
  for written comments and hearing, unless the it finds that notice is
  impracticable, unnecessary, or not in the public interest.

  C. If the MPUC finds that a requested waiver is consistent with gas
  pipeline safety and is otherwise justified, the waiver must be issued
  under appropriate terms and conditions with a statement of reasons for
  granting the waiver.

  D. If the MPUC finds a requested waiver is inconsistent with gas
  pipeline safety or is otherwise unjustified, the request must be
  denied, and the applicant notified of the reasons for denial.

  E. The MPUC must give PHMSA written notice of each waiver at least 60
  days before it becomes effective. Each notice of waiver must provide
  the following information:

  1. The name, address, and telephone number of the applicant;

  2. The safety standards involved;

  3. A description of the pipeline facilities involved;

  4. The justification for the waiver, including the reasons why the
  standards are not appropriate and why the waiver is consistent with
  gas pipeline safety.
