MCLEESE, Associate Judge: Petitioner Potomac Electric Power Company

(“Pepco”) challenges the determination of the Public Service Commission of the

District of Columbia (the “Commission”) precluding Pepco from recovering from

rate-paying customers Pepco’s pre-2018 costs incurred in connection with an

investigation into environmental conditions at Pepco’s Benning Road facility. We

vacate and remand for further proceedings.

I. Factual and Procedural Background

Except as noted, the following basic facts appear to be undisputed. Pepco

operates the Benning Road facility, which occupies an approximately seventy-

seven-acre site in the District of Columbia, bordering the Anacostia River.

Approximately twenty percent of the site was once occupied by a Pepco electrical

generating station. The generating station ceased operations in 2012 and was

subsequently demolished. Most of the site is now occupied by a service center

engaged in activities related to the construction, operation, and maintenance of

Pepco’s electric-power transmission and distribution system.

In 1999, Pepco applied to the Commission for approval to divest its generation

assets. Pepco reached a settlement with the parties to that proceeding, and the

Commission approved the settlement. The settlement agreement provided that if

Pepco decided not to sell the Benning Road generating station, Pepco would be 3

barred from recovering “stranded costs associated with” that generating station.

“Stranded costs” are infrastructure investments that a utility is unable to recover due

to changes in regulatory or market conditions. See, e.g., Cent. Vt. Pub. Serv. Corp.

v. Fed. Energy Regul. Comm’n, 214 F.3d 1366, 1367-68 (D.C. Cir. 2000) (describing

different varieties of stranded costs).

In 2008, a contractor working for the United States Environmental Protection

Agency (“EPA”) assessed the Benning Road site to determine whether action needed

to be taken on the site pursuant to the federal Comprehensive Environmental

Response, Compensation, and Liability Act, 42 U.S.C. § 9601 et seq. The contractor

reviewed the history of the site, physically examined the site, and took soil and water

samples on a specific date.

The contractor’s subsequent report noted that Pepco had conducted generation

and distribution activities on the site. The report described “numerous known spills

and leaks” of polychlorinated biphenyls (“PCBs”)—a contaminant of concern—at

the Benning Road site. Some of those known spills and leaks appear to have arisen

from generation activities and some appear to have arisen from

distribution/transmission activities. For some known spills and leaks, the nature of

the activity causing the spill is not clear from the description in the report. 4

The report explained that high levels of PCB contamination were found in the

Anacostia River downstream from the site. Although the site was properly managed

at the time of inspection and PCB spills were addressed promptly, the report

concluded that the PCB contamination of the Anacostia River was likely attributable

to activities on the site. The report identified the “sludge dewatering area” adjacent

to the former generation-station cooling towers as the only remaining potential

“uncontained” source of contaminants to the environment at the site. The report

indicated that the sludge dewatering area could “release [PCBs and other]

compounds via overland flow . . . into the storm water system that eventually

discharges into the Anacostia River.” The report also noted, however, that other

“historical releases of . . . hazardous substances from the site contributed to the

contamination documented in [the] Anacostia River.”

After the report was issued, the District of Columbia Department of the

Environment, now known as the Department of Energy and Environment (“DOEE”),

notified Pepco that it intended to sue Pepco for abatement of the hazardous

conditions identified in the report. The DOEE notice letter asserted that the

conditions DOEE sought to have abated resulted “from the disposal and

management of solid wastes at [the Benning Road] facility,” which the notice letter

stated was “used by Pepco to manage all operations and maintain all equipment

associated with its electrical distribution system.” The letter cited six “documented 5

releases of PCBs” described in the EPA report as the basis for the intended lawsuit

against Pepco. As previously noted, some of those known spills and leaks appear to

be attributable to generation activities and some appear to be attributable to

distribution/transmission activities.

In 2011, the District of Columbia sued Pepco and related companies seeking

abatement of conditions and recovery of costs relating to environmental

contamination on and near the Benning Road site. The complaint does not appear

to be in the record before the Commission, but the complaint is described in a

subsequent consent decree that is in the record. According to the consent decree, the

complaint relied on the EPA report, referred to the six documented releases of PCBs,

and alleged that “PCBs that have been released at the Facility over time may have

migrated from the property into the sediment of the adjacent Anacostia River.” In

the consent decree, Pepco agreed to conduct a remedial investigation and feasibility

study (“RI/FS”) to inform future remedial actions at the Benning Road site.

The stated purposes of the consent decree included “determin[ing] the nature

and extent of contamination and any threat to the public health, welfare, or the

environment caused by the release or threatened release of hazardous substances,

pollutants[,] or contaminants at or from the Facility, by obligating Pepco to conduct

a remedial investigation,” and “identify[ing] and evaluat[ing] alternatives for 6
