Background
This case concerns the allocation of maintenance and inspection responsibility for drainage facilities on the Delair Bridge, a railroad bridge carrying Conrail’s Delair branch rail line over Interstate 95 in Philadelphia. In June 2018, multiple motor vehicles collided on I-95 near the Delair Bridge, and plaintiffs in subsequent lawsuits alleged that ponding water on I-95, caused by inadequate drainage maintenance, contributed to the crashes. After PennDOT took the position that Conrail bore responsibility for inspection of the bridge’s drainage system, Conrail petitioned the PUC for a declaratory order clarifying the parties’ respective duties under a 1966 PUC order that had originally approved construction of I-95 beneath the existing railroad right-of-way.
The 1966 Order had allocated construction and maintenance responsibilities between PennDOT and Conrail’s predecessor, the Pennsylvania Railroad Company. Paragraph 30 assigned Conrail responsibility for maintaining “the entire superstructure including the fixed and expansion bearings” of the bridge. Paragraph 33 assigned PennDOT responsibility for “the remainder of the crossing project, including the entire substructure of the new railroad bridge . . . and all drainage facilities pertinent to the improvement.” On January 2, 2025, the PUC issued a declaratory order concluding that Conrail, not PennDOT, bore responsibility for the drainage facilities, reasoning that drainage was part of the bridge superstructure and that paragraph 33’s reference to “drainage facilities” applied only to relocated Thompson Street based on the absence of an Oxford comma.
The Court’s Holding
The Commonwealth Court vacated the PUC’s declaratory order and remanded with direction that PUC enter an order finding that the 1966 Order assigned drainage facility maintenance to PennDOT. The court first held that a deferential standard of review applied: because PUC was interpreting its own prior order rather than a statute or regulation, the court would not set aside PUC’s construction unless it was “clearly erroneous, arbitrary, and unsupported by evidence.” The court rejected Conrail’s argument that the Statutory Construction Act of 1972 governed, noting that the Act by its express terms applies only to statutes, regulations, and documents that incorporate it.
Even under this deferential standard, the court found PUC’s interpretation clearly erroneous. The court identified three critical flaws. First, neither the preamble nor paragraph 30 of the 1966 Order mentioned drainage facilities in connection with Conrail’s responsibilities. Second, the PUC entirely overlooked paragraph 6, which assigned PennDOT responsibility for constructing “drainage facilities pertinent thereto” for the railroad bridges, demonstrating that drainage was always PennDOT’s domain. Third, the PUC’s Oxford comma argument was untenable because the 1966 Order did not consistently use Oxford commas, and if the comma was intentionally omitted, a missing conjunction (“and”) before the Thompson Street reference would create an even more glaring textual problem. Finally, the court noted that the 1966 Order consistently used “the improvement” in the singular to refer to the entire crossing project, not just Thompson Street.
Key Takeaways
- When the PUC interprets its own prior orders, a court will not overturn the interpretation unless it is “clearly erroneous, arbitrary, and unsupported by evidence,” a standard more deferential than ordinary substantial-evidence review but not bulletproof.
- The Statutory Construction Act of 1972 does not apply to PUC’s interpretation of its own orders; it is limited by its express terms to statutes, regulations, and documents that incorporate the Act.
- Courts will read agency orders as an integrated whole, and an agency cannot selectively parse one paragraph while ignoring another that uses nearly identical language to allocate the same category of responsibility.
- The absence of an Oxford comma, standing alone, is insufficient to override the plain meaning of an agency order when the document as a whole uses the disputed term (“the improvement”) consistently in a broader sense.
Why It Matters
This decision is significant for practitioners navigating PUC-ordered maintenance allocations at railroad-highway crossings across Pennsylvania. The court’s willingness to vacate even under a highly deferential standard signals that PUC interpretations of historic orders must be firmly grounded in the full text, not selective readings of individual paragraphs. The court’s analysis of PUC’s exclusive jurisdiction over rail-highway crossings under 66 Pa. C.S. sections 2702 and 2704 reaffirms that this authority extends to declaratory orders clarifying decades-old allocation disputes, but that PUC may not exercise that expertise to reach results the order’s language does not support.
The opinion also preserves PUC’s ability to prospectively reassign maintenance duties in a subsequent proceeding, a practical safety valve for situations where sixty-year-old allocations no longer reflect current infrastructure realities. Practitioners representing utilities or transportation agencies in legacy crossing disputes should carefully review the full text of original PUC orders and present competing paragraphs as part of a comprehensive textual analysis rather than relying on individual provisions in isolation.
