OPINION BY SENIOR JUDGE LEAVITT FILED: May 5, 2023

Sunoco Pipeline, L.P. (Sunoco) petitions for this Court’s review of an adju dication 1 of the Pennsylvania Public Utility Commission (Commission) that imposed a civil penalty in the amount of $2,000 for violations of the Pennsylvania Public Utility Code 2 and federal regulations applicable to gas pipelines. 3 Sunoco
contends that the Commission erred and abused its discretion

. First, the federal regulations on pipeline construction were not an issue raised in any of the formal complaints adjudicated by the Commission. Second, Sunoco cannot be sanctioned
or ordered to revise its public awareness program unless or until the Commission promulgates a regulation that authorizes the ordered revisions

. The Commission has
filed a motion to dismiss Sunoco’s appeal of its adjudication related to the
construction of Sunoco’s pipeline s as moot because those pipelines are no longer

transporting highly volatile liquids (HVL s )

. For the reasons to follow, we deny the
Commission’s motion to dismiss , and w e reverse in part and affirm in part the
Commission’s remediation and civil penalty order to Sunoco

. Background Since 2014, as authorized by it s certificate s of public convenience
, Sunoco has transported HVL s , including butane, ethane and propane or a combination thereof, between Delmont, Westmoreland County, and Twin Oaks, Delaware County . Sunoco’s Mariner East pipeline system consist s of three pipelines. The Mariner East 1 (ME1) is an 8

- inch diameter pipeline built in the
1930s that ha s been repurposed to transport HVLs. The Mariner East 2 (ME2) is a newly constructed 20

- inch diameter pipeline that, at certain points, uses a 12

- inch “workaround pipeline” that was also built in the 1930s. The Mariner East 2X (ME2X) is a new 1 6

- inch diameter pipeline under construction. Admini strative Law Judge Initial Decision at 21

- 22, Findings of Fact (F.F.) Nos. 45

- 48.

Between July 2018 and January 2019, several formal complaints were filed to challenge Sunoco’s Mariner East pipelines as unsafe and not providing a reasonable utility service . The formal complaints were filed by Meghan Flynn, Rosemary Fuller, Michael Walsh, Nancy Harkins, Gerald McMullen, Caroline Hughes, and Melissa Haines (Flynn Complainants) ; the Andover Homeowners’ Association, Inc. (Andover) ; Melissa DiBerna r dino ; Rebecc a Britto n ; and Laura Obenski (collectively, Complainants) and A ligned I ntervenors

. 4 The formal complaints sought to stop the operation of the ME1 and ME2 pipelines and
construction of the ME2X pipelines , including the workaround pipelines used for

4 The A ligned I ntervenors include Downingtown Area School Distri ct , Rose Tree Media School District , Twin Valley School District, East Goshen Township , West Whiteland Township, Uwchlan Township, Middletown Township, Delaware County, West Chester Area School District, Thornbury Township, Chester County, Edgmont Township , Clean Air Council, and Senator Thomas Killion. Chester County and Clean Air Council have filed briefs in support of the Commission

HVL s . I n the alternative, the complaints sought to have Sunoco ordered to take
certain measures to protect public safety
, including an enhancement to its public awareness program and integrity management plan.

More specifically, t he Flynn complaint alleged that Sunoco ’s ME1 and workaround pipelines and valve stations have been unlawfully sited in densely populated areas of Chester and Delaware Counties. A large HVL leak at any location along the ME1 or a workaround pipeline creates the risk of “hundreds of fatalities.” Flynn Second Amended Complaint ¶ 30 ; Reproduced Record at 152a (R.R. __). The complaint also alleged that Sunoco failed to establish an ad equate emergency planning and public awareness program
, as required by Section 1501 of the Public Utility Code, 66 Pa. C.S. §1501; the Commission’s r egulation at 52 Pa. Code §59.33 ; and the f ederal r egulation at 49 C.F.R. § 195.440 ( governing public awareness )

. T he

c omplaint further alleged that Sunoco did not meet the federal minimum safety
standards in light of a 2017 leak in Morgantown , Pennsylvania, and a 2018 rupture in Beaver County , Pennsylvania

. Due to these safety problems, the complaint requested the Commission to order an independent party to do a “remaining life study” on Sunoco’s ME1 and workaround pipelines in Chester and Delaware
Counties

. Flynn Second Amended Complaint at 36; R.R. 179a.

The DiB ernardino complaint averred
, inter alia
, that Sunoco installed its pipelines in unstable soil; with coating flaws; and too close to other HVL pipelines
, which was “too dangerous to be permitted.” DiBernardino Complaint ¶ 14 ; R.R. 264a. The complaint alleged that Sunoco violated federal safety regulations by repurposing the pipelines built in the 1930s that “ha [ ve ] a long history
of leaks
, ” including a 2018 leak in Delaware County. DiBernardino Complaint ¶ 16;
R.R. 264a

. The complaint questioned the integrity of the “ 1930s pipelines ” and requested the Commission to require Sunoco to establish “a credible and adequate

emergency / evacuation plan [

. ] ” DiBernardino Complaint at 15 ; R.R. 270a. The4

complaint challenged Sunoco ’s exis ting public awareness program under 49 C.F.R. § 195.440 as inadequate because it did not explain how a gas leak would be detected

or be communicated to the public

. Further, s chool districts and municipalities have received “inadequate responses , or none at all ” to their requests for information
needed for their emergency response planning

. DiBernardino Complaint ¶ 23 ; R.R.
266a. The complaint requested the Commission to order Sunoco to suspend all horizontal directional drillings for installation of the ME2 and ME2X pipelines until “the risk to the public” is assessed and the “necessary geo

- physical tests and analyses” are performed. DiBernardino Complaint at 15; R.R. 270a.

The Britton complaint asserted that because Sunoco’s public awareness program account ed only for those living within the 1000

- f oo t impact radius
, it was insufficient

. T he Mariner East pipelines run through high consequence areas with private dwellings, industrial buildings, and places of public assembly , in violat ion
of 49 C.F.R. §195.210(a)

. The complaint alleged that a valve station in Upper
Uwchlan Township present s an unreasonable risk to school students and staff across
the street

. Britton Complaint ¶ 32 ; R.R. 370a

- 71a

. The complaint asserted that Sunoco’s public awareness program violated 49 C.F.R. § 195.440 because it did not provide sufficient information . Britton Complaint ¶¶11

- 14; R.R. 364a

- 65a. It also
raised concerns about the impact of Sunoco’s horizontal drilli ng upon public drinking water. The Britton complaint request ed the Commission to find that
Sunoco’s public awareness program, emergency alert system, and evacuation procedures d id not constitute saf e and reasonable services
, as required under 66 Pa. C.S. §1501

. Britton Complaint at 22

- 24 ; R.R. 376a

- 7 8 a.

The Obenski complaint also alleged that Sunoco’s public awareness

program violated 49 C.F.R. § 195.440 because it was not sufficiently informative on leak detection and evacuation procedures

. Obensk i Complaint ¶1; R.R. 635a

- 37a.
S chool districts were unable to maintain “updated, actionable, and reliable5

emergency preparedness plans” due to “ lack of cooperation from Sunoco. ” Obenski Complaint ¶ 3 ; R.R. 638a. The complaint requested
, inter alia
, that the Commission
find that Sunoco’s public awareness program “has resulted in significant ga ps in the ability of” local government to “appropriately plan for the hazards introduced by the Mariner East Project [

. ] ” Obenski Complaint at 8

- 9; R.R. 640a

- 41 a.

Finally, Andover ’s complaint asserted that Sunoco’s public awareness

program violated 49 C.F.R. §195.440 because it had left the association’s members “without either a credible notification system or emergency plan

. ” Andover Complaint ¶ 98 ; R.R. 749a

. This was unreasonable because the ME1 leaked three
times in 2016 and 2017, and the 12

- inch workaround pipeline has leaked at least four
times in Chester and Delaware Counties since 1987. Andover Complaint ¶ 77 ; R.R.
745a. Andover asserted that Sunoco’s emergency evacuation plan
, i.e ., “immediate

on

- foot self

- evacuation in the correct upwind or uphill direction,” was not workable
, particularly for evacuations at night or during inclement weather. Andover Complaint ¶ 93 ; R.R. 748a. Andover alleged that i t had made numerous requests of
Sunoco “ for a credible notification system and evacuation guidance” but received
neither. Andover Complaint ¶81; R.R. 746a. Andover requested the Commission

to order Mariner East operations limited or stopped until Sunoco provides a “comprehensive risk assessment and credible notification and evacuation plan.” Andover Complaint at 23 ; R.R. 751a.

The complaints were assigned to an Administrative Law Judge ( ALJ ) for disposition. By order of June 6, 2019, t he ALJ consolidated the proceedings on the formal complaints. The ALJ’s order identified “six central issues” that follow:

(1) the safety and integrity of ME1, ME2, ME2X, and the 12

- inch pipeline; (2) the safety of the location of the pipelines and related eq uipment (i.e. valve stations); (3) the adequacy of Sunoco , L.P.’s public awareness program;6 (4) the adequacy of Sunoco , L.P. ’s emergency response procedures and training; (5) Sunoco, L.P.’s integrity management protocols; and (6) the safety of the construction of ME2 an d ME2X.
ALJ Order, 6/6/2019, at 4; R.R. 845a.

The ALJ conducted in

- person hearings i n 2019 , at which members of the public appeared

. Sunoco
, Complainants and A ligned I ntervenor s all filed written direct and rebuttal testimony between January and August of 2020 . The ALJ then conducted evidentiary hearings from September 29, 2020
, to October 9, 2020, and

on October 13

- 14, 2020. All parties filed post

- hearing briefs.

On April 12, 2021, th e ALJ issued an Initial Decision denying Complainants ’ request that S unoco cease construction and operation of the Mariner
East pipeline s

. The ALJ reasoned that the Commission lack ed jurisdiction over pipeline siting; regardless, the location of the Mariner East pipelines and the valve
stations compl ie d with both state and federal law. The ALJ also concluded that Complainants and A ligned I ntervenors failed to prove that Sunoco violat ed the integrity management 5 provision in 49 C.F.R. § 195.452 or the cathodic protection provision in 49 C.F.R. § 195.571. The ALJ found that Sunoco followed its integrity management plan
, which treats all segments of the Mariner East pipelines in Chester and Delaware Counties as if they are located in a high consequence area. ALJ Initial
Decision at 115. Because the integrity management program requires on

- going testing, maintenance, and repair of the pipelines to keep them in compliance with regulatory requirements, the ALJ denied Complainants’ request that Sunoco hire an

5 “Integrity management” refers to a process in which pipeline operators “devote additional resources to preventing and m itigating hazards to pipeline safety within [high consequence areas].” Commission Adjudication at 24 n.8. As the Commission explained, the federal pipeline safety regulations use the concept of “high consequence areas,” or HCA, to “identify specific loca les and areas where a failure could have the most significant adverse consequences.” Id. The federal regulations require “the use of an in

- line inspection device or comparable technology to ensure hazardous liquid pipeline integrity within HCAs.” Id.7

independent party to conduct a “remaining life study” on the ME1 and the workaround pipelin es. Id. at 112.

The ALJ determined, however, that Sunoco had violated Section 1501
of the Public Utility Code, 66 Pa. C.S. §1501, in two ways. First, the ME1 and the
workaround pipelines did not satisfy the depth of cover and spacing regulations set
for th in 49 C.F.R. §§ 195.210(b), 195.248, and 195.250

. Second, Sunoco’s public

awareness program did not satisfy the requirements of 49 C.F.R. § 195.440

.

D epth of C over and D istance of P ipelines With respect to the violation of 49 C.F.R. §§ 195.210(b), 195.248, and
195.250 , t he ALJ relied on the presentation of complainant Gerald McMullen that
the ME1 is located within 50 feet of several homes , including his, a s well as the Chester County Library

. He testified that the ME1 is “shallow
, ” as are the “new pipelines that are proposed to go in

. ” Notes of Testimony (N.T.), 10/23/2019 , at 979; R.R. 929a. McMullen presented a photograph of an 8

- inch ME1 pipeline and another pipeline that were exposed in a dry creek bed near Whiteland West Apartments

. R.R. 950a. Another one of McMullen’s photograph s show ed that a n underground pipeline transect ed a ball field. R.R. 952a.

As to the distance between the pipelines, McMullen presented a n exhibit he created indicating “the distances between the two existing pipelines and the two proposed pipelines” between his home and the Chester County Library

. N.T. 951; R.R. 901a. The exhibit s howed the ME1 and the 12

- inch workaround pipelines placed 25 feet apart, and the ME1, ME2X, ME2, and the workaround pipelines placed 8 to 9 feet apart from each other

. Id

. ; see also R.R. 946a. McMullen also presented a photograph taken from his property showing Sunoco pipeline markers.
He testified , in relevant part :

Following the markers straight down, that is [ME]1. The markers to the right of that are the potential path of [ME]2X.8 Right on the other side of that wooden fence is [ME]2, and closest to the library is the 12

- inch workaround line.
N.T. 952; R.R. 902a. McMullen expressed concern that “there are four pipes in such a small space” because, should there be a leak or an accident, h e and other residents would have difficulty in following Sunoco’s recommendation to evacuate from the

scene, “upwind, uphill,” on foot

. N.T. 951

- 52; R.R. 901a

- 02a. In addition, McMullen presented photograph s of a parking lot in Exton, Chester County, showing markers on the ground for two pipelines buried underneath , one of them being ME1 , but he did not specify the distance between the two pipelines. R.R.
951a.
Based on McMullen’s testimon y about the shallow pipes and photographs, t he ALJ found that the ME1 pipeline is not always covered with 48
i nches of ground cover when located within 50 feet of dwellings
, as required under 49 C.F.R. §195.210(b). 6 ALJ Initial Decision at 93. Nevertheless, t he ALJ acknowledged that neither complainants nor Sunoco “offered any measurements regarding depth of cover of a pipe within 50 feet of the library and Mr. McMullen’s
house.” Id

. The ALJ explained , however, that her finding was consistent with the Pennsylvania Department of Environmental Protection’s September 11, 2019, order,

6 It states: (b) No pipeline may be located within 50 feet (15 meters) of any private dwelling, or any industrial building or place of public assembly in which persons work, congregate, or assemble, unless it is provided with at least 12 inches (305 millimet ers) of cover in addition to that prescribed in §195.248. 49 C.F.R. §195.210(b)

. Section 195.248 (a) provides: (a ) Unless specifically exempted in this subpart, all pipe must be buried so that it is below the level of cultivation. Except as provided in paragraph (b) of this section, the pipe must be installed so that the cover between the top of the pipe and the ground level, road bed, river bottom, or underwater natural bottom (as determined by recognized and generally accepted practices), as applicable, complies with the following table [requiring a maximum of 36 inches of coverage in industrial, commercial, and residential areas]. 49 C.F.R. §195.2 48 (a)

which directed Sunoco to cover exposed pipelines at 43 locations across the state
, one of which involved the transport of HVLs

. Id

. at 97.

The ALJ found that Sunoco violated 49 C.F.R. § 195.250, which requires a 12

- inch separation between pipelines transporting HVLs and underground

structures. 7 Despite McMullen ’s testimony and his diagram show ing t hat the ME1, ME2X, ME2, and the workaround pipelines are about 8 to 9 feet apart from each other, t he ALJ found that the pip elines under the parking lot and between McMullen’s home and the Chester County Library were placed approximately 8
inches apart

. In making these findings, the ALJ observed that Matt Gordon, senior
director of Sunoco operations in Chester and Delaware Coun ties , did not refute
McMullen ’s testimony

. With regard to McMullen’s photographs of exposed pipe lines in the stream bed next to Whiteland West Apartments , Gordon testified that those pipelines had been abandoned and were no longer in use

. H e could not recall
the distance between th os e two exposed pipelines

. Gordon testified there is 48 inches of cover over ME2, but he did not speak to the depth of cover over ME1 or
the 12

- inch workaround pipeline near McMullen’ s home , which McMullen
described as “shallow.” ALJ Initial Decision at 93. T he ALJ took judicial notice of Gordon’s testimony in a prior proceeding, Dinniman v. Sunoco Pipeline, L.P ., P

2018

- 3001453 and C

- 2018

- 3001451 ( Dinniman Proceeding), 8 that “10 fe et

7 Section 195. 25 0 provides: Any pipe installed underground must have at least 12 inches (305 millimeters) of clearance between the outside of the pipe and the extremity of any other underground structure, except that for drainage tile the minimum clearance may be less tha n 12 inches (305 millimeters) but not less than 2 inches (51 millimeters). However, where 12 inches (305 millimeters) of clearance is impracticable, the clearance may be reduced if adequate provisions are made for corrosion control. 49 C.F.R. §195.250

. 8 I n that case, state senator Andrew E. Dinniman filed a formal complaint with the Commission seeking to enjoin Sunoco’s operation of ME1 and the construction of ME2 and ME2X in West10

separation was a standard distance buffer between the ME1 and ME2 and ME2X pipelines.” ALJ Initial Decision at 94.

T he ALJ concluded that Sunoco did not refute Complainants’ evidence
that the ME1 was not buried at the correct depth and was too close to the other pipes

. Public Awareness Program With regard to Sunoco’s public awareness program , the ALJ made
numerous and detailed findings

. Beginning in 2014, Sunoco has done public awareness mailings for the Mariner East pipelines : one to the affected public ; one to excavators and public officials ; and one to emergency responders. The public pamphlet and emergency responder pamphlet state that natural gas liquids ( NGL s )

are flammable and can ignite when [they] come [] into contact with

an ignition sou rce. Exposure can cause moderate irritation including headaches and dizziness. NGL may contain hydrogen sulfide H 2 S.

ALJ Initial Decision at 134 (citing Sunoco Exhibits GG

- 1 and GG

- 2)

. However, t he pamphlet s do not mention “d eath, burns, serious injuries, frostbite or asphyxiation ”

as possible consequences of a pipeline rupture or ignition

. ALJ Initial Decision at
49
, F.F. No. 244. I n the event of a leak, the pamphlets advise one to leave the area
on foot to a safe distance ; warn others; turn of f electrical equipment; and call 911.
Each individual must determine a “safe distance” on a case

- by

- case basis. Id . at 51
, F.F. No. 261. The pamphlets do not address the evacuation of individuals with physical or mental limitations.

Whiteland Township that had allegedly caused sinkholes. The Commission affir med the ALJ’s emergency interim order directing Sunoco to cease construction of ME2 and ME2X. This Court reversed the Commission’s adjudication in Sunoco Pipeline L.P. v. Dinniman , 217 A.3d 1283 (Pa. Cmwlth. 2019) , and remanded the matter to the Commissio n with instructions to dissolve the interim emergency injunction and dismiss Dinniman’s complaint for lack of standing.11 Since 2014, Sunoco has developed and maintained websites with information about the Mariner East pipelines, including one dedicated specifically to pipeline safety. ALJ Initial Decision at 53, F.F. No. 270. Sunoco has also
disseminate d public awareness a nd safety information about the Mariner East pipelines through social media. Id ., F.F. No. 271. Since 2016, Sunoco has used billboards, radio advertising, and television advertising to provide information about the Mariner East pipelines

. Id ., F.F. No. 27 2

. Sunoco has held open houses in Chester and Delaware Counties to provide information about the construction of the Mariner East pipelines. Sunoco has engaged a consult ant that specialize s in community planning and emergency preparedness
, and Sunoco h as met with school
districts in Delaware and Chester Counties. Id ., F.F. No. 27 6

.

In 2019, Sunoco’s public awareness program was audited as part of the Public Awareness Program Effectiveness Research Survey (“PAPERS”), a program developed by the American Petroleum Institute (API)

. ALJ Initial Decisio n at 54
, F.F. No. 27 7

. The audit concluded that Sunoco’s public awareness program “ was effective in achieving program objectives and was comparable to the other pipeline operators’ programs. ” Id

. , F.F. No. 278.

Additionally, Sunoco me e t s with emergency responders in Delaware
and Chester Counties every other month to provide training, tours, and exercises.
ALJ Initial Decision at 59

- 63 , F.F. Nos. 314

- 45. Gregory Noll, Sunoco’s expert witness in emergency planning and emergency response training, conducted Mariner Emergency Responder Outreach (MERO) trainings in Delaware and Chester
Counties in 2017 and 2020. Sunoco participates in annual Coordinated Response
Exercise s (CoRE) for emergency responders in Delaware and Chester Counties

. Sunoco p articipates in bi

- weekly meetings with townships across Delaware and
Chester Countie s and monthly meetings with Chester County Association of Township Officials to provide project updates. The ALJ found that the level of12

training and funding for equipment provided by Sunoco in Delaware and Chester
Counties exceeds that of any other NGL p ipeline operator in these counties

. ALJ Initial Decision at 59, F.F. No. 320.

Sunoco ’s MERO training provides that the decision to evacuate or shelter in place should be made by the emergency responder on a case

- by

- case basis

. Delaware County has adopted an emergency response plan that includes factors to
be considered in making that decision

. Id . at 55, F.F. No. 290. Accordingly, Sunoco does not provide notice of a pipeline release directly to schools and municipalities.

The ALJ found that Sunoco must directly notify schools and municipalities in the event of a rupture or release because they are also “first responders.” Id . at 57, F.F. No s . 30 2

- 03

. M unicipalities and school districts are required to create their emergency response plans under the Emergency Management Services Code, 35 Pa. C.S. §§ 7101

- 79A33
, and they need information
from Sunoco to develop their plans. ALJ Initial Decision at 60, F.F. No. 323. The
information Sunoco has provided to municipalities and school districts in Delaware
and Chester Counties includ e s :

(i) the location of the pipelines; (ii) the location of the valve stations; (iii) proximity to schools; (iv) the products in pipelines and their physical properties; (v) the hazards of those products; (vi) a rule of thumb for a safe distance in the event of a significant release; (vii) the direction of flow of product in the pipelines; (viii) that in the event of a catastrophic release the product between the corresponding va lve sites will be released; (ix) plume modeling; (x) [ Sunoco ’s] integrity management, security and PHMSA compliance programs; and (xi) [ Sunoco ’s ] remote monitoring center for leak detection.
ALJ Initial Decision at 60, F.F. No. 324 (quotations omitted)

.

In sum, the ALJ found that Sunoco’s public awareness program
satisfied “many requirements ” of the federal pipeline safety regulations , including
the use of a one

- call notification system, identification of a pipeline release, steps t o13

take in the event of a release, procedure s to report a release, and limitations on cell phone use during a release. ALJ Initial Decision at 54
, F.F. No. 281

. Accordingly,

t he ALJ denied Complainants’ requests for mass warning systems, addition of
odora nts to the NGLs in the pipelines, and notice of evacuation procedures, as well as their requests to have Sunoco revise its public mailers to address “what a safe distance is before using a cellular phone, wind direction and other means of transporting persons other than walking away and upwind from a release.” ALJ
Initial Decision at 140
, 161, 167

- 69. The ALJ concluded that these requests should
be addressed in the Commission ’s on

- going rulemaking proceeding that was considering amendments to the public awareness regulations

.

On the other hand, t he ALJ found inadequacies in Sunoco’s public

awareness program

. William H. Turner, Deputy Director for C hester County ’s Department of Emergency Services, testified that Sunoco’s CoRE meetings and MERO trainings were insufficient for planning purposes

. Turner testified that trying
to get information from Sunoco for the County’s emergency response plan w as li ke hitting a “brick wall.” ALJ Initial Decision at 147. Should a leak occur in the pipeline valve located near the Downingtown Area School District , Turner estimated
that it would take 10 minutes for the pipeline operator to arrive on the scene with a gas meter. Turner believed that Sunoco should enhance its public outreach and education program s by providing municipalities and school districts information needed to develop their emergency response plan s

. Id

. at 148

- 4 9.

In these findings
, t he ALJ credited the testimony of Timothy Hubbard, the fire marshal and emergency management officer in Charlestown Township, Chester County. H ubbard explained it was difficult to have “consistent contact”
with Sunoco on information such as “what product is flowing at any given time, when it’s flowing, when products are changing and the nature of the products.” ALJ
Initial Decision at 148. Hubbard testified there was a lack of “real, true and credible14

assistance” from Sunoco
, such as “expert advice from the perspective of a pipeline operator or resources in the event that an emergency were to occur.” Id

. Hubbard
does not know , for example, how much product would be released in a leak before
the shut

- off valves can be activat ed.

The ALJ found emergency planning agencies, first responders, residents, school districts, and municipalities were “confused and concerned” about
how to protect their communities in the event of a gas leak . ALJ Initial Decision at
149. S chool offici als did not know whether cellphone s can be safely used in an evacuation that could involve thousands of children. Witnesses from multiple school districts expressed confusion over the first steps to take in a pipeline emergency.
West Chester and Twin Val ley School Districts planned to have students shelter in place until receiving further notice
, but this contravened Sunoco’s recommendation

to evacuate from the scene of a pipeline emergency, on foot, immediately. Hubbard,
who also serve s as the chief security officer of the Downingtown Area School District, questioned Sunoco’s recommendation to evacuate on foot and upwind

. The Downingtown Area School Distri ct has a student population that range s in age from kindergarten through twelfth grade
, and it includes special needs children

. D eciding
wind direction is a “hit

- or

- miss” situation , particularly since winds fluctuate

. Id . at
154. If a leak occurred near the playground , it could asphyxiat e children

. Should a car drive through a leak, it could ignite an explosion. Emile Lonardi, the superintendent of Downingtown Area School District testified that she “has been given conflicting information” and did not have a “credible or practical or realistic plan in place to keep the students safe in the event of leak” from the Mariner East pipeline s

. Id . at 153.

The ALJ found a “need for emergency response measures by [Sunoco] that will maximize the timeliness and effectiveness of the school districts’ response
at each of their facilities.” ALJ Initial Decision at 156. The ALJ found Sunoco’s15

existing CoRE exercises and MERO tr aining on accidents to be inadequate. Accordingly, the ALJ concluded Sunoco ’s failure to engage with the local emergency personnel upon their request constituted “unreasonable service,” in
violation of 66 Pa. C.S. §1501 and 52 Pa. Code §59.33. ALJ Initia l Decision at 151.
Sunoco ’s failure to provide sufficient guidance to schools located within a few
hundred feet of the Mariner East pipelines specifically violated 49 C.F.R. § 195.440(d)(4) , which require s Sunoco to reach out to “appropriate government

org anizations” with “steps that should be taken” in the event of an emergency. ALJ
Initial Decision at 151. The ALJ was persuaded that school districts should receive
the same information provided to emergency responder s in light of their responsibility to plan for emergencies

.

The ALJ also found deficiencies in Sunoco’s required communication with the public

. The federal regulation at 49 C.F.R. § 195.440(a) requires that a pipeline operator develop and implement a written continuing public education

pro gram that follows the guidance provided by API Recommended Practice (RP)
1162. In turn, Section 4.2 of API RP 1162 provides that “operators should provide a very broad overview of potential hazards , their potential consequences and the
measures undertaken by the operator to prevent or mitigate the risks from the pipelines.” R.R 1146a (emphasis added). 9

9 API R ECOMMENDED P RACTICE 1162 (First Edition, December 2003), Public Awareness Programs for Pipeline Operators , at 19

. Section 4.2 o f API RP 1162 states: Hazard Awareness and Prevention Measures Operators should provide a very broad overview of potential hazards, their potential consequences and the measures undertaken by the operator to prevent or mitigate the risks from pipelines (in cluding, at the operator’s discretion, an overview of the industry’s safety record). Additionally, operators should provide an overview of their preventative measures to help assure safety and prevent incidents. The scope of the hazard awareness and prev ention message should be more detailed for the emergency responder audience than for other audiences, and should include how to obtain more specific information upon request from the operator. R.R. 1146a.16 Based on these findings of fact and conclusions of law, t he ALJ recommended the imposition of a civil penalty of $ 2 ,000 on Sunoco for “having violated regulations: 49 C

of Law No. 71. Of th e $2,000 civil penalty, $1,000 was imposed for Sunoco’s “unreasonable service [] to not oblige [the school districts and municipalities’] request” for “more information and emergency responder training

. ” ALJ Initial
Decision at 140. The remaining $1,000 penalty, accordingly, was for the violation of the pipeline depth of cover and distancing regulations. The ALJ also recommended injunctive

- type relief to address these violations

. Commission Adjudication
Sunoco filed exception s to the ALJ’s I nitial D ecision

. It challenged the
ALJ’s determination that it had violated the pipeline d epth of c over and d istance

r egulations in 49 C.F.R. §§ 195.210(b), 195.248, and 195.250 , which were not an issue in the proceeding. In addition to violating Sunoco’s right to due process, the
ALJ misinterpreted th e cited federal regulations , which did not apply to the ME1
and the workaround pipelines
, and made findings of fact unsupported b y substantial evidence. Sunoco objected to the ALJ’s order to revise its public awareness program because it imposed a burden not required under Pennsylvania or federal law or imposed on any other pipeline operator

.

By adjudication of November 18, 2021, t he Commission denied
Sunoco’s exceptions. The Commission adopted the ALJ’s proposed findings of fact,
conclusions of law and recommended order as its own

. The Commission imposed a
civil penalty in the total amount of $2,000

.

With regard to Sunoco’s public awareness program, the Commission
also ordered remediation measures. They included the follow ing :17 18. That Sunoco Pipeline, L.P. is directed to contact Chester County Commissioners, Delaware County Commissioners, and all mun icipalities’ supervisors therein within thirty (30) days of the date of Final entry of this Opinion and Order in this consolidated proceeding to arrange for meeting(s) (either remotely or in

- person or a combination thereof as mutually agreeable) to: a) establish emergency contact list information for the operator’s controller and county liaison(s); b) disclose to Middletown Township, Delaware County, and Chester County any damage or potential damage to their respective facilities or properties resulting from the operation of the pipelines; c) assist with the establishment of emergency plans for first responders in the event of a leak, release, explosion, or other failure of the pipeline system and the communication of all information required under state and federal law to enable Middletown, Delaware County, and Chester County to prepare such emergency plans; d) inform and educate Middletown and Delaware County officials and staff on proper and effective disaster prevention and disaster response, including participation in “tabletop” activities and/or “boots on ground” exercises as referenced by Sunoco in its letter dated August 13, 2020 and admitted as exhibit SUNOCO

- 50 and as requested by Complainants and their aligned Intervenors; e) develop standard not ification templates for public warning systems to be used during a pipeline emergency and develop emergency classification levels (i.e., a small leak release versus a rupture event) which are specifically designed to make the public aware of the situation; f) provide detailed information regarding its infrastructure;18 g) assist in the development of an evacuation plan for use by municipalities with concept of how evacuation would occur; h) create a public outreach and public education program; i) introduce t o the operator’s designated County liaison(s) a tour of the area surrounding the pipeline facilities such that the liaison(s) may be made aware of the geology, terrain and location of schools, libraries, retirement and apartment housing as well as train tr acks, roadways, recreational parks, housing developments such that the liaison may provide local emergency planning assistance to local emergency management partners that could consist of dedicated employee(s) and or funding to support additional employees; j) notify not only the County but all municipalities in Delaware or Chester County of anticipated, scheduled or commenced work done in those counties; k) notify County officials, in advance, of any pipeline activity, such as simulations, testing
, routine maintenance, repairs, etc.; l) subject to a nondisclosure agreement, share with Chester County’s Department of Emergency Services maps of all transmission lines listing material moved, pipeline diameter, mainline valve locations and maximum opera ting pressures (MOP), and maximum allowable operating pressure (MAOP) and information about the location of any anomalies that merit pressure reduction in the pipeline and the presence of “immediate,” “60

Commission Adju dication at 113

- 15.

As to d epth of c over over, and d istance between
, Sunoco’s pipelines
, the Commission ordered remediation measures that follow :

24. That Sunoco Pipeline, L.P. is directed to conduct a depth of

cover and distance between other underground pipelines/structures survey regarding Mariner East 1 and the 12

- inch workaround pipelines as long as they are purposed for carrying highly volatile liquids a/k/a natural gas liquids. 25. That Sunoco Pipeline, L.P. is directed to bury its Marine r East 1 and 12

- inch pipelines as long as these pipelines are transporting Highly Volatile Liquids such that they are at least twelve inches apart from other underground pipes or structures unless the operator can show it is providing adequate corrosion

co ntrol in these areas where the pipes are less than twelve inches apart. 26. That within one hundred twenty (120) days of the date of Final entry of this Opinion and Order, Sunoco Pipeline, L.P. shall file a report with the Commission certifying whether Mar iner East 1 and the 12

- inch workaround pipelines that are transporting highly volatile liquids within Chester and Delaware Counties are buried so that they are below the level of cultivation and so the cover between top of pipe and ground level, road bed, river bottom or underwater natural bottom is in compliance with minimum regulatory requirements and the distance between pipeline exteriors and the exteriors of other underground pipelines/utility structures are at least twelve inches apart unless adequate corrosive control action can be shown, and that a copy of the report be served upon the Commission’s Bureau of Technical Utility Services and the Bureau of Investigation and Enforcement. 27. That the report as described in Ordering Paragraph No. 26 shall contain a corrective action plan regarding any areas of operating pipelines (including Mariner East 1, 8

- inch pipeline, and the 12

- inch workaround pipelines) carrying highly volatile liquids in Delaware and Chester Counties in need of remediation where th ere is lack of required cover and/or proper distance between other structures/pipelines in order to bring these pipelines up to federal minimum codified requirements.20 28. That the report as described in Ordering Paragraph No. 26 shall be filed annually for a period of three (3) years. Commission Adjudication at 11 6

- 17.

Sunoco appealed to this Court. On November 18, 2022, the
Commission filed a motion to dismiss S unoco’s petition for review , in part , on grounds of mootness

. Appeal

On appeal, 10 Sunoco raises two issues for our review. First, Sunoco argues that the Commission erred in holding that it violated the federal regulation s

on depth of cover and distance between pipelines . Th is issue was not raised in any of the formal complai nts and, thus, Sunoco was deprived of notice and an opportunity to be heard. Alternatively, Sunoco argues that the Commission
misconstrued and mis applied the federal regulations because they govern the
construction of new pipelines built after 1981
, when the federal regulations on depth
of cover and pipeline distance were promulgated

. T he ME1 and the workaround pipelines are exempt because they were constructed in the 1930s

. Further, o ther federal regulations govern the operation and maintenance of existing gas pipelines

. In any case, the ALJ’s findings of fact on depth of cover and spacing of the ME1
and the workaround pipelines are not supported by substantial evidence. Second,

10 On a petition to review an adjudication of the Commission , our standard of review is limited to determining whether substantial evidence supports the necessary findings of fact, whether the Commission erred as a matter of law, and whether constitutional ri ghts were violated. Retail Energy Supply Association v. Pennsylvania Public Utility Commission
, 185 A.3d 1206 , 1220 (Pa. Cmwlth. 2018) (quotations omitted) . We defer to the Commission’s interpretation of the Public Utility Code and its own regulations un less the Commission’s interpretations are clearly erroneous. Id

. (quotations omitted). We may not substitute our judgment for that of the Commission “when substantial evidence supports the [Commission’s] decision on a matter within the [C] ommission ’ s exp ertise.” Id

. (quotations omitted). “Judicial deference is even more necessary when the statutory scheme is technically complex.” Id . (quotations omitted). On issues of law, “our standard of review is de novo and our scope of review is plenary.” Id

.21

Sunoco argues that the Commission erred and abused its discretion in ordering
Sunoco to revise its public awareness program in ways not required by existing state
and federal regulation s

. Effectively, the Commission’s order to Sunoco constitutes the promulgation of a regulation that cannot be done in the course of an adju dication
but only in a rule

- making proceeding.

I n its motion to dismiss , the Commission argues that Sunoco’s appeal
of its adjudication with respect to the d epth of c over and d istance of the ME1 and
12

- inch workaround pipelines is moot because those pipelines are no longer transporting HVLs. On the merits, t he Commission argues that it acted within its authority under the Public Utility Code and the applicable regulations to ensure that
Suno co provi ded adequate, safe, and reasonable service . Further, it argues that the Commission’s interpretation of the Public Utility Code and applicable regulations, including the federal regulations , is entitled to deference. 11

Mootness We begin with the Commission’s motion to dismiss Sunoco’s appeal for mootness. The Commission asserts that Sunoco’s appeal on the Commission’s adjudication regarding “ depth of cover and pipeline distance applied directly and exclusively to Sunoco’s [ ME1 ] and 12

- inch workaround pipelines as long as these

11 The Commission regulations at 52 Pa. Code §59.33, promulgated pursuant to 66 Pa. C.S. §1501
, require that hazardous liquid utilities shall have minimum safety standards consistent with the pipeline safety laws at 49 U.S.C. §§60101

- 60503 and the regulation s at 49 C.F.R. Parts §§191

- 193, 195, and 199. The Commission regulations adopt federal safety standards for hazardous liquid facilities. These standards include what materials must be used for new hazardous liquid pipelines, and how those pipelines shoul d be constructed, as well as corrosion control, maintenance and testing of existing hazardous liquid pipelines. The standards also address emergency preparedness and public awareness plans.22

pipelines are transporting [ HVLs ] ” is now moot. Commission Motion, ¶5 (emphasis in original). T he ME1 and the 12

- inch workaround pipelines are no longer transporting HVLs

. Sunoco responds that because the adjudication ordered a civil penalty for violating the depth of cover and distance regulations , its appeal cannot
be moot . If Sunoco succeeds in its appeal, it can recover its payment. Further, an adju dicated violation will be used to establish a penalty in a future enforcement
action against Sunoco , should one occur

. See 52 Pa. Code §69.1201 (c)(6) (providing
that frequent, recurrent violations by a public utility may result in a higher penalty ).

Generally, a case will be dismissed as moot if there exists no actual case or controversy. Fraternal Order of Police v. City of Philadelphia
, 789 A.2d 858 (Pa. Cmwlth. 2002)

. The existence of a case or controversy requires

(1) a legal controversy that is real and not hypothetical, (2) a legal controversy that affects an individual in a concrete manner so as to provide the factual predicate for a reasoned adjudication, and (3) a legal controversy with sufficiently adverse parties so as to sharpen the issue s for judicial resolution. Mistich v. Pennsylvania Board of Probation and Parole , 863 A.2d 116, 119 (Pa. Cmwlth. 1994) (quoting Dow Chemical Company v. United States Environmental
Protection Agency , 605 F.2d 673, 678 (3rd Cir.1979) )

. A controversy must continue through all stages of judicial proceedings, trial and appellate, and the parties must continue to have a “personal stake in the outcome” of the lawsuit. Mistich , 863 A.2d at 119 (quoting Lewis v. Continental Bank Corp oration , 494 U.S. 472, 477

– 78 (1990) ). An exception to mootness will be found where (1) the conduct complained of is capable of repetition yet likely to evade judicial review; (2) the case
involves issues of great public importance ; or (3) one party will suffer a d etriment
in the absence of a court determination. Horsehead Resource Development Company, Inc. v. Department of Environmental Protection , 780 A.2d 856
, 858 (Pa.23

Cmwlth. 2001)

. It is within the court ’ s discretion to decide “ substantial questions, otherwise moot, which are capable of repetition unless settled.” Colonial Gardens Nursing Homes, Inc. v. Bachman
, 373 A.2d 748
, 750 (Pa. 19 77 )

.

Sunoco’s decision to discontinue using the M E 1 and the 12

- inch workaround pipelines for HVLs does not moot its challenge to the adjudicated
violation of the depth of cover and distance regulations because Sunoco has paid a $1,000 civil penalty for that violation and would like it refunded . Additiona lly, nothing in the Commission’s order prevents Sunoco from resuming the transportation of HVLs in the M E 1 and the 12

- inch workaround pipelines at some point in the future.

Accordingly , we deny the Commission’s m otion. We turn, then, to the
merits of Sunoco’s issues on appeal

.

Depth of Cover and Distance Pipeline Regulation Sunoco argues that it was denied due process because the pipeline depth of cover and distance regulations found in 49 C.F.R. §§195.210, 195.248 or 195.250 were not cited in any of the formal complaints. T he Flynn c omplain t originally cited
the federal depth of cover regulation , but not the distance regulation . However, the Flyn n Complainants withdrew tha t complaint and did not include that issue in their amended complaint. N one o f the other formal complaints cited these federal regulations , and n one of the Complainants or Aligned Intervenors raised these
federal regulations in their post

- hearing briefs. Sunoco argues that t he ALJ erred in raising, sua sponte , the depth of cover and distance regulation s for the first time in
her Initial Decision.

The Commission responds that the Flynn complaint alleged a violation
of 66 Pa. C.S. §1501, and the pipeline safety regulation at 52 Pa. Code §59.33. This put Sunoco on notice that compliance with all state and federal pipeline safety regulations would be at issue , e ven without a specific citation to 49 C.F.R.24

§§195.210, 195.248 or 195.2 5 0

. Further, t he ALJ’s pre

- hearing order stated that one of the issues to be addressed was “the s afety and integrity of ME1, ME2, ME2X,
and the 12

- inch pipelines” and “the safety of the locations of the pipelines[.]”
Commission Brief at 5 3 (quoting R.R. 844a

- 46a).

It is beyond peradventure that an administrative hearing is limited to the legal que stions raised by the parties. The hearing tribunal may not
, sua sponte , augment the subject matter of a proceeding. As this Court has recently explained:

Sua sponte consideration of an issue deprives counsel of the opportunity to brief and argue the issue s and the court of the benefit of counsel’s advocacy. Moreover, raising issues sua sponte after the record is closed and without notice to the parties constitutes a due process violation.
Orange Stones Co mpany v. Borough of Hamburg Zoning Hearing B oard , 991 A.2d 996, 999 (Pa. Cmwlth. 2010) ( quotations omitted).

On due process, this Court has directed that a utility must be “afforded
a reasonabl e opportunity to kno w the nature of its opponents’ contentions so that it can prepare a suitably responsi ve answer.” Duquesne Light Company v. Pennsylvania Public Utility Commission , 507 A.2d 433, 437 (Pa. Cmwlth. 1986).
See also Commonwealth v. Public Utility Commission , 3 31 A.2d 598, 600 (Pa. Cmwlth. 1975) (“anyone involved in a proceeding ” is entitled to “notice of specific charges or complaints”). In Duquesne Light Company , the Commission ordered an electric utility to refund customers the cost of replacement service re quired by the utility’s shutdown of a nuclear plant. The utility challenged the Commission’s order on grounds that it did not receive adequate notice that the reasonableness of its actions immediately preceding the shutdown order was a matter in issue . T his Court agreed, holding that the Commission violated due process by deciding an issue for which the utility did not receive notice

.25 In Pocono Water Company v. Pennsylvania Public Utility Commission
, 630 A.2d 971 (Pa. Cmwlth. 1993), a formal complaint alleg ed inadequate service
from a water utility

. Sua sponte , the ALJ imposed a penalty upon the water company
because it had not complied with a prior order of the Commission to build storage
tanks. In its appeal, t he utility asserted a violati on of due process because there was

no notice that a prior order was at issue . Reversing the Commission’s order, this
Court explained as follows :

Due process in matters before the Commission requires that a party be afforded reasonable notice of the natur e of the allegations against it so that the party can prepare a suitable defense. Duquesne Light Co. v. Pennsylvania Public Utility Commission , 507 A.2d 433

. Although the Commission may take notice of results it reached in other cases, the record must reflect that the parties had notice that the Commission would consider such evidence. City of Erie v. Pennsylvania Public Utility Commission , [] 398 A.2d 1084 ( [Pa. Cmwlth.] 1979)

. This Court has held that the Commission violated due process rights when it assessed liability by determining an issue which the utility had not been afforded a reasonable opportunity to address at an evidentiary hearing.

Pocono Water Company , 630 A.2d at 973.

Here, the depth of cover regulation was expressly withdrawn from the Flynn complaint
, and the pipeline separation issue was never raised

. Rather, the
formal complaints raised general safety concerns about the Mariner East pipeline
system. Ironically, the ALJ did not make a specific finding that the system was unsafe. More to the point
, a general allegation about “safety” did not put Sunoco on notice that it should prepare to defend the spacing and depth of its pipelines
, which

are very specific in their terms

. 12 Further
, Complainants and their A ligned

12 By contrast, the formal complaints put Sunoco on notice that it should prepare to defend its public awareness program. See Flynn Complaint ¶¶115

- 122 ; R.R. 174a

- 75a ( Sunoco failed to provide a n adequate public awareness program under 49 C.F.R

. §195.440 ); DiBernardino Complaint ¶¶22

- 32 ; R.R. 266a

- 68a ( Sunoco failed to provide an adequate emergency planning and26

I ntervenors made no argument in post

- hearing briefs with respect to depth of cover

or pipeline distancing. They sought neither injunctive relief n or a civil penalty under
49 C.F.R. §§195.210, 195.248 or 195.250.

We reject the Commission’s argument that a general citation to 52 Pa.
Code §59.33
, which adopted Part 1 95 of the C.F.R., was sufficient to put Sunoco on notice that it was charged with a v iolation of the specific requirements of 49 C.F.R. §§195.210, 195.248 or 195.250

. As in Duquesne Light Company and Pocono Water Company , this lack of notice to Sunoco violate d due process. Accordingly, we

reverse the Commission’s holding that Sunoco violated the pipeline depth of cover and distance regulations. 13 Public Awareness Program

Sunoco argues, next, that the Commission erred in ordering Sunoco to make changes to its public awareness program that are no t set forth in any state or federal law. Further, the Commission’s adjudication is in consistent with the ALJ’s findings about Sunoco’s public awareness program implemented in Delaware and
Chester Counties

.

The ALJ found that Sunoco does more training and funds more equipment purchases than any other pipeline operator in the area

. ALJ Initial

public awareness program under 49 C.F.R

. §195.440 ); Britton Complaint ¶¶5, 11 ; R.R. 361a, 364a (p olitical subdivisions were not presented with adequate information from Sunoco to adequately prepare and m itigate for the public health and safety under 49 C.F.R

. §195.440 ); Obenski Complaint ¶1 ; R.R. 635a

- 37a ( Sunoco’s public awareness program failed to appropriately educate all members of the community who are at risk from the operation of the Mariner East n etwork ); and Andover Complaint ¶¶87, 93, 97, 98 ; R.R. 747a

- 49a ( Sunoco’s public awareness program leaves association members without either a credible notification system or emergency plan ).

13 Because we reverse the Commission’s adjudication insofar that S unoco violated the federal pipeline depth of cover and distance regulations , we need not address Sunoco’s argument s that the Commission misinterpreted the se federal depth of cover and distance regulations because they apply only to the construction of new pipelines, not to the maintenance or operation of an existing pipeline. Likewise, we need not address Sunoco’s argument that, in any case, the findings of fact relevant to a purported violation are not supported by substantial evidence.27

Decision at 59, F.F. No. 320. The ALJ also found that Sunoco has informed the municipalities and school districts in Delaware and Chester Counties of the location
of its pipelines and valve stations and their proximity to schools; the products in the pipelines and their physical properties; the hazards of those products; a rule of t humb for a safe distance in the event of a significant release; the direction of flow of product in the pipeline s ; the product between the corresponding valve sites that will
be released in the event of a catastrophic release ; plume modeling; Sunoco’s
inte grity management, security and PHMSA compliance programs; and Sunoco’s remote monitoring center for leak detection. ALJ Initial Decision at 60, F.F. No.
324

. These findings demonstrate Sunoco ’s compli ance with the minimum requirements for its public awa reness program set forth in 49 C.F.R. § 195.440 and
API RP 1162

. Nevertheless, t he Commission concluded that Sunoco’s public

awareness program did not meet the requirement of “reasonable service” under 66
Pa. C.S. § 1501 and , thus, imposed more requirements listed in Paragraph No. 18 of
its order . The Commission did so without citing any “authority mandating these meetings or requiring Sunoco [] to undertake all the various elements of Order ¶18.”
Sunoco Brief at 59.

Sunoco argue s that the Commission ’s “reasonable service” expectations are not grounded in an existing state or federal law . T he ALJ acknowledged in the Initial Decision that the Commission has undertaken rulemaking in this area and is seeking comments regarding: (1) utility interaction with local government officials on such topics as emergency planning and response
coordination and periodic drills with utility/municipal coordination; (2) periodic public awareness meetings with municipal offic ials and the public; and (3) enhancements to public utility public awareness programs under 49 C.F.R. §195.440
and API RP 1162. ALJ Initial Decision at 77. Sunoco argues that the Commission28

has imposed these proposed rulemaking requirements on Sunoco
, in advance of their adoption. The Commission responds that as a public utility , Sunoco must provide
safe and reasonable service , which includes the obligation to “use every reasonable effort to properly warn and protect the public from danger .” 52 Pa. Code §59.33(a)

. The federal regulation at 49 C.F.R. §195.440 specifically require s enhance d communication with local public officials where the pipeline is located in a high

consequence area , which includes Delaware and Chester Counties. The Commission argues that Sunoco failed to meet this obligation.

The Commission asserts the Public Utility Code gives the Commission the discretion to order a utility to take action in the interest of reasonable service without a specific regulation

. T he Commission may “ prescribe
, by regulation or order
, ” the “ repairs, changes, alterations, extensions, substitutions, or improvements in facilities as shall be reasonably necessary and proper for the safety, accommodation, and convenience of the public. ” 66 Pa. C.S

. §150 5(a) (emphasis added)

. 14 That the Commission i s concurrently exercising its rulemaking power did not prevent it from prescribing specific measures to address the safety and
reasonableness of Sunoco ’s Mariner East pipeline system under authority of 66 Pa.
C.S. § 1505 (a).

14 It reads : (a) General rule.

-- Whenever the commission, after reasonable notice and hearing, upon its own motion or upon complaint, finds that the service or facilities of any public utility are unreasonable, unsafe, inadequate, insufficient, or unreasonably discrim inatory, or otherwise in violation of this part, the commission shall determine and prescribe, by regulation or order, the reasonable, safe, adequate, sufficient, service or facilities to be observed, furnished, enforced, or employed, including all such re pairs, changes, alterations, extensions, substitutions, or improvements in facilities as shall be reasonably necessary and proper for the safety, accommodation, and convenience of the public. 66 Pa. C.S. §1505 (a)

.29 The Commission contends that its interpretation of the Public Utility
Code and its own regulations is entitled to deference. Commission Brief at 34 ( citing Crown Castle NG East LLC v. Pennsylvania Public Utility Co mmission , 234 A.3d 665, 678 (Pa. 2020)). The regulation at 49 C.F.R. §195.440 requires the public

awareness program to “ be as comprehensive as necessary to reach all areas in which the operator transports hazardous liquid [.]” 49 C.F.R. §195.440(f). The Commission asserts that it acted “well within the purpose and intent” of the federal regulation s by pr es cribing reasonable public awareness measures appropriate for the high consequence areas of Chester and Delaware Counties. Commission Brief at
49.
In addition, Section 1501 of the Public Utility Code requires safe and
reasonable service. It states :

Every public utility shall furnish and maintain adequate, efficient, safe, and reasonable service and facilities
, and shall make all such repairs, changes, alterations, substitutions, extensions, and improvements in or to such service and facilities as shall be necessary or proper for the accommodation, convenience, and safety of its patrons, employees, and the public. Such service also shall be reasonably c ontinuous and without unreasonable interruptions or delay. Such service and facilities shall be in conformity with the regulations and orders of the commission.
66 Pa. C.S. §1501 (emphasis added). Consistent with Section 1501 , t he Commission
has promul gated 52 Pa. Code §59.33 , which has adopted the federal regulations on natural gas safety. It states
, in relevant part , as follows :

( a) Responsibility

. Each public utility shall at all times use every reasonable effort to properly warn and protect the public from danger, and shall exercise reasonable care to reduce the hazards to which employees, customers and others may be subjected to by reason of its e quipment and facilities. (b) Safety code

. The minimum safety standards for all natural gas and hazardous liquid public utilities in this Commonwealth shall30 be those issued under the pipeline safety laws as found in 49 U.S.C.A. §§60101

- 60503 and as implemen ted at 49 CFR Parts 191

- 193, 195 and 199, including all subsequent amendments thereto. Future Federal amendments to 49 CFR Parts 191

- 193, 195 and 199, as amended or modified by the Federal government, shall have the effect of amending or modifying the Com mission’s regulations with regard to the minimum safety standards for all natural gas and hazardous liquid public utilities.
52 Pa. Code §59.33(a), (b).

The federal regulation “prescribes safety standards and reporting requirements for pipeline facilit ies used in the transportation of hazardous liquids[.]” 49 C.F.R. §195.0. With respect to “public awareness
, ” it states :

(a) Each pipeline operator must develop and implement a written continuing public education program that follows the guidance provide d in the American Petroleum Institute ’ s (API) Recommended Practice (RP) 1162 (incorporated by reference, see §195.3). (b) The operator ’ s program must follow the general program recommendations of API RP 1162 and assess the unique attributes and characteristics of the operator ’ s pipeline and facilities

. (c) The operator must follow the general program recommendations, including baseline and supplemental requirements of API RP 1162 , unless the operator provides justification in its program or procedural manual as to why compliance with all or certain provisions of the recommended practice is not practicable and not necessary for safety. (d) The operator’s program must specifically include provisions to educate the public, appropriate government organizations, and persons engaged in excavation related activities on: (1) Use of a one

- call notification system prior to excavation and other damage prevention activities; (2) Possible hazards associated with unintended releases from a hazardous liquid or carbon dioxide pipeline facility; (3) Physical indications that such a release may have occurred;31 (4) Steps that should be taken for public safety in the event of a hazardous liquid or carbon dioxide pipeline release; and (5) Procedures to report such a n event. (e) The program must include activities to advise affected municipalities, school districts, businesses, and residents of pipeline facility locations. (f) The program and the media used must be as comprehensive as necessary to reach all areas in w hich the operator transports hazardous liquid or carbon dioxide. * * * * (i) The operator ’ s program documentation and evaluation results must be available for periodic review by appropriate regulatory agencies.
49 C.F.R. §195.440 (emphasis added).

In sum, a pipeline operator must follow “ the general program recommendations, including baseline and supplemental requirements of API RP
1162 [.]” 49 C.F.R . §195.440 (c) (emphasis added) . In turn, API RP 1162 defines
, in relevant part, “ b aseline p ublic a wareness p rogram[,]” as

[r] efer[ring] to general program recommendations, set forth in [ API RP] 116 2 [

. ] T

he baseline recommendations do not take into consideration the unique attributes and characteristics of individual pipeline operators’ pipeline and fa cilities. Supplemental or enhanced program components are described in the RP to provide guidelines to the operator for enhancing its Public Awareness Programs. R.R. 1129a (emphasis added). Satisfying the “baseline recommendations” does not preclude “enh anced program components.” Id

. Accordingly, API RP 1162 states
that a “one

- size

- fits

- all” Public Awareness Program across all pipeline systems would not be the most effective approach. R.R. 1134a.

Relevant hereto, API RP 1162 includes Table 2.1
, which sets forth the baseline messages to be included in pipeline operator s’ public awareness32

communications

. Table 2.1 then provides that in high consequence areas , or HCA, pipeline operators should increase the frequency of their communications, provide supplemental messages, and have personal contact with the local officials

and reasonable service

. Povacz v. Pennsylvania Public Utility Commission
, 280
A.3d 975 , 100 5 (Pa. 2022) ( citing Lansberry v. Pennsylvania Public Utility
Commission , 578 A.2d 600 , 602 (Pa. Cmwlth. 1990) ). Complainants presented
evidence that Sunoco ’s CoRE meetings and MERO trainings did not provide the
information needed by local officials to develop their emergency response plans;
that Sunoco refused to meet with local public officials and emergency respon ders outside the CoRE meetings and MERO trainings ; that emergency responders, school districts, and residents are confused and concerned over steps to be taken in a pipeline emergency ; and that local public officials found it difficult to obtain
additional information from Sunoco needed for emergency preparedness

. The ALJ
found that because Delaware and Ches ter Counties have been designated high consequence areas, Sunoco wa s “required to devote additional focus, effort and analysis to ensure the integrity of its pipelines.” ALJ Initial Decision at 140. Accordingly, “ if the school districts and municipalities and counties want more information and emergency responder training, then it is unreaso nable service for the operator to not oblige this request.” Id

.

The Commission agreed. Accordingly, the Commission ordered the payment of a $1,000 civil penalty and directed Sunoco to arrange meetings with the
commissioners of Delaware and Chester Count ies and with the relevant municipalities’ supervisors to assist their emergency preparedness and evacuation plans

. Sunoco argues that this order exceeded the Commission’s statutory authority

. Sunoco Brief at 58

- 59 (citing Commission Adjudication, 11/18/ 2021, ¶18). We are not persuaded

.

Section 1505 of the Public Utility Code authorizes the Commission to prescribe remedial action upon a violation of Section 1501 “as shall be reasonably

necess ary and proper for the safety, accommodation, and convenience of the public.” 66 Pa. C.S. §150 5

. The language in both 49 C.F.R. §195.440 and API RP 116234

provides that a public awareness program must be adapted to meet the particular
circumstances and con ditions present. The regulation specifically permits “appropriate regulatory agencies” to review operators’ program documentation and
evaluation results. 49 C.F.R. §195.440 (i). More specifically, Section 2.8 of API RP
1162 , Table 2.1, provides that operators, in their communications with emergency officials and local public officials
, should address, inter alia
, “pipeline purpose and reliability ,” “a wareness of hazards and prevention measures undertaken ,”

“ emergency preparedness communications
, ” and “how to get additional
information. ” R.R. 1138a

. Where a pipeline is located in a high consequence area, operators should have “personal contact” with local public officials and provide supplemental messages including “[m]aintenance construction act ivity

. ” Id

. S upplemental activity for communications with emergency officials should include “emergency tabletop, deployment exercises,” “ facility tour,” and “open house.” Id

.

W e conclude that the remedial actions ordered by the Commission with respect to Sunoco’s public awareness program fall within the scope of 49 C.F.R. §195.440 and API RP 1162 , which were adopted by the Commission at 52 Pa

. Code §59.33. These regulations authorized the Commission to order revisions in Sunoco’s existing program to ensure the delivery of safe and reasonable service

.

Notably, in adopting the ALJ’s Initial Decision, the Commission denied Complainants’ requests to include information in Sunoco’s public mailers such as
“what a safe distance is before using a cellular phone, wind direction and other means of transporting persons other than walking away and upwind from a release.”
ALJ Initial Decision at 140. These requests, as the ALJ concluded, are outside the scope of state and federal law and, thus, should be referred to the Commission’s rulemaking proceeding. The Commission’s injunctive relief was narrowly tailored to address the ways in which Sunoco’s public awareness prog ram , as implemented
,35

has not satisfied Section 1501 of the Public Utility Code and Section 59.33 of the Commission regulations.

For these reasons, w e affirm the Commission’s adjudication that
Sunoco’s public awareness program did not comply with 66 Pa. C.S

. §150 1 and 52
Pa. Code § 59.33
, and a civil penalty of $1,000

. Conclusion
Sunoco’s decision to discontinue transporting HVLs through ME1 and
the workaround pipelines did not render irrelevant the constraints imposed by the
Commission on Sunoco
, which may decide to use the pipelines to transport HVLs
in the future

. Accordingly, we deny the Commission’s motion to dismiss. W e hold
that Sunoco’s purported violation of the pipeline depth of cover and distance regulations set forth in 49 C.F.R. §§ 195.210( b), 195.248, and 195.250 was not a
matter at issue in the litigation before the Commission , and, thus, reverse the Commission’s adjudication thereon

. However, we hold that the Commission did not err in concluding that Sunoco’s public awareness program fai led to meet the
reasonable service standard required by 66 Pa. C.S. §150 1

. Accordingly, we affirm
the Commission’s adjudication requiring changes to Sunoco’s public awareness program and t he pay ment of a $1,000 civil penalty

.

For these reasons, we affirm in part and reverse in part the Commission’s adjudication.
