decision approving, denying, or ordering modifications, in whole or in part, to the
utility’s gas infrastructure plan application filed in accordance with paragraph
4552(d).
(b) The Commission’s decision regarding the gas infrastructure plan application shall

presumption of prudence of the cost estimate for a planned project if the
Commission determines the record supports the reasonableness and maturity of
the cost estimate and evaluation of alternatives, as applicable.

paragraph 4552 (d), either in whole or in part, the utility shall make changes to
the plan in response to the Commission's decision. Within 60 days of the
issuance of a Commission decision disapproving a plan, the utility shall file an
amended plan with the Commission and shall provide the amended plan to all
parties who participated in the application proceeding concerning the utility’s
plan. All such parties may participate in any hearings regarding the amended
plan.
