Steam Heat Distribution System Safety Regulations
[47 Pa.B. 7314]
[Saturday, December 2, 2017]The Pennsylvania Public Utility Commission, on August 3, 2017, adopted a final rulemaking order to amend its existing steam heating service regulations and provide new steam safety requirements.
Executive Summary
Section 1501 of the Public Utility Code requires every public utility in Pennsylvania to ''maintain adequate, efficient, safe, and reasonable service and facilities'' and to ''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.'' 66 Pa.C.S. § 1501. Pursuant to that authority and Section 501 of the Public Utility Code, 66 Pa.C.S. § 501, the Pennsylvania Public Utility Commission (Commission or PUC) has amended and added safety regulations governing steam heat distribution facilities of steam utilities under the Commission's jurisdiction.
The Commission adopted these regulations to facilitate safety inspections of steam utilities by the PUC's Pipeline Safety Division. The regulations modernize and update the accident reporting regulations similar to recently revised regulations for electric, gas, and water utilities. The regulations add requirements for notification of major construction, operating and maintenance plans, customer education, recordkeeping, employee training, periodic inspections, steam leaks and emergency reports, welding, and service outage reports. The regulations also emphasize that steam utilities must adhere to Pennsylvania One Call (the Underground Utility Line Protection Act) and comply with standard safety codes.

Steam Heat Distribution System Safety Regulations, 52 Pa. Code Chapters 61 and 67; L-2015-2498111
Final Rulemaking Order By the Commission:
By Order entered November 5, 2015, the Pennsylvania Public Utility Commission (Commission) issued a Proposed Rulemaking Order to amend and expand its steam heating service regulations in Chapter 61 of the Pennsylvania Code. See 52 Pa. Code §§ 61.1—61.31. Pursuant to its authority and duty under the Public Utility Code, 66 Pa.C.S. §§ 501, 1501, the Commission proposed revisions and updates to Sections 61.1, 61.11, and 61.12. The Commission proposed adding a new subchapter titled ''Safety Requirements,'' adding Sections 61.41—61.53. The Commission also proposed minor revisions to Chapter 67 to apply the service outage regulations to jurisdictional steam distribution companies.
Comments to the Proposed Rulemaking Order were filed by NRG Energy Center Harrisburg LLC and NRG Energy Center Pittsburgh LLC (collectively the ''NRG Companies''), Veolia Energy Philadelphia, Inc. (''VEPI'') and the Independent Regulatory Review Commission (''IRRC''). The Commission has reviewed those comments and now issues this Final Rulemaking Order.
Background
The Commission first promulgated the current regulations governing steam heating service on March 11, 1946. See 52 Pa. Code §§ 61.1—61.27, 61.31. The Commission promulgated Section 61.28 regarding the filing of annual financial reports on May 7, 1988. See 18 Pa.B. 2106; see 52 Pa. Code § 61.28. Otherwise, Chapter 61 governing steam heating service has not been revised or amended. The Commission maintains jurisdiction over only a few steam heating utilities: the aforementioned NRG Companies and VEPI. Due to the low number of jurisdictional steam utilities and the perception of fewer risks and dangers presented in the regulation of steam than in the regulation of gas, the Commission historically retained very few staff and inspectors to oversee the few steam utilities operating in the Commonwealth.
While steam distribution systems present fewer dangers than natural gas distribution systems, accidents and incidents can still occur. For example, on July 18, 2007, a 20-inch diameter steam pipeline owned and operated by the Consolidated Edison Company of New York, Inc. (Con Ed) ruptured in Midtown Manhattan in New York City, where escaping steam broke through the pavement, creating a large crater at a busy intersection.1 The rupture also impacted surrounding telecommunications facilities and natural gas and electric transmission and distribution facilities. The New York Public Service Commission (NYPSC), which regulates jurisdictional steam corporations in New York, determined that Con Ed's procedures did not adequately address the regulatory requirements of 16 NYCRR 420.4(b)(5). See N.Y. PUB. SERV. LAW § 80 (general powers of the NYPSC as to steam heating). Therefore, the NYPSC identified a number of recommendations for improvement by Con Ed to its procedures, inspections, system surveillance, training, facility repairs, and feasibility analyses.2
State representatives of the Pennsylvania General Assembly, understanding that the Commonwealth has similar steam pipelines and facilities, asked the PUC's Gas Safety Division, now the Pipeline Safety Division, to spearhead inspections of steam heat facilities in Pennsylvania. Three PUC Pipeline Safety inspectors began steam training in 2009, first attending a week-long training with Con Ed in New York City. In 2010, three PUC Pipeline Safety staff began attending IDEA (International District Energy Association) training on a semi-yearly to yearly basis. This international training broadly covers all topics and facets of steam distribution.
The Commission's Pipeline Safety Division created a steam inspection form, based in significant part on New York's steam distribution system safety regulations. See 16 NYCRR 420.1—420.15. Accordingly, the Commission sought in the Proposed Rulemaking Order to memorialize the requirements provided in the steam inspection form through the promulgation of steam heat safety regulations.
In the spirit of the Regulatory Review Act, 71 P.S. 745.2, and in order to facilitate the regulatory review process, Commission staff informally proposed draft regulations outside the regulatory review process and discussed those draft regulations with company representatives of the NRG Companies and VEPI. Commission staff held numerous collaborations and discussions with NRG and VEPI.
Discussion
As stated in the November 15, 2015 Proposed Rulemaking Order, the Commission embarked on this rulemaking proceeding in order to modernize and update its existing steam heat regulations and to add steam heat safety regulations to empower the PUC's Pipeline Safety Division to conduct inspections of jurisdictional steam distribution facilities for the purpose of ensuring public safety and protecting the public interest. Section 1501 of the Public Utility Code requires every public utility in Pennsylvania to ''maintain adequate, efficient, safe, and reasonable service and facilities'' and to ''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.'' 66 Pa.C.S. § 1501. Pursuant to this authority and the Commission's power to promulgate regulations, 66 Pa.C.S. § 501(b), and the Commonwealth Documents Law, 45 P.S. § 1201, the Commission proposed steam heat safety regulations in order to prescribe the minimum safety requirements for the design, fabrication, installation, inspection, testing, operation, and maintenance of steam distribution systems in the Commonwealth of Pennsylvania.
As stated previously, the only active jurisdictional steam public utilities are the NRG Companies and VEPI, as those entities invoke public utility status by ''distributing or furnishing. . .steam. . .to or for the public for compensation.'' See 66 Pa.C.S. § 102. Notably, in the future the Commission and the Pipeline Safety Division may uncover other steam facilities in the Commonwealth that distribute steam to or for the public for compensation and therefore require a certificate of public convenience from the Commission in order to legally operate. See 66 Pa.C.S. §§ 1101—1103.
Accordingly, the Commission regulates the distribution facilities of jurisdictional steam public utilities. 66 Pa.C.S. §§ 102, 501. The Commission does not have safety jurisdiction over steam distribution companies that do not qualify as public utilities under the Public Utility Code. As to the production of steam, the Pennsylvania Department of Labor & Industry retains legal authority and regulatory oversight by conducting the inspections of the boilers3 that produce the steam. 35 P.S. § 1331.1; see 34 Pa. Code §§ 3a.1—3a.171.
In the Proposed Rulemaking Order, the Commission proposed specific revisions and additions to Chapter 61 and Chapter 67 of its regulations.
Revisions to Existing Sections 61.1, 61.11, and 61.12.
Section 61.1 Definitions
As stated in the Proposed Rulemaking Order, the proposed amendment to the definition of service line reflects a more specific, modern definition, and explains that the ''point of service termination is the customer's property line, unless otherwise provided by contract.'' See Annex A, Section 61.1. We proposed deleting the distinctions between low pressure and high pressure, as those archaic distinctions are not very helpful in the steam distribution industry as pressures utilized by companies differ and vary on a wider spectrum. Pressures can range from 100 pounds per square inch gauge (psig) to 210 psig, depending on the system and the company. We also proposed amending the definition for service line of the customer to stress and clarify the importance of the specific service line termination point and not just the general service line. See Annex A, Section 61.1.
Comments from VEPI and IRRC and Resolution
VEPI proposed two additional definitions for ''steam distribution system'' and ''steam utility'' to distinguish between distribution system safety and general plant or facility safety. IRRC recommended adding a definition for ''termination point'' to be used in the definitions of ''service line'' and ''service line of the customer.'' IRRC also recommended that the Commission should clarify the terms ''steam public utility,'' ''steam utility,'' ''utility,'' ''steam facility,'' ''facility,'' ''steam distribution system,'' and ''steam distribution utility'' as the terms appear to be used interchangeably.
We agree with suggestions of VEPI and IRRC and have made the appropriate changes in new Annex A. Specifically, we use the term ''steam utility'' throughout the regulations.
Section 61.11 Accidents
On September 23, 2011, the Commission entered a Final Rulemaking Order pertaining to public utilities' service outage response and restoration practices. See Docket L-2009-2104274 (Final Rulemaking Order entered Sep. 23, 2011); see 14 Pa.B. 4511 (effective Jan. 7, 2012). In that Final Rulemaking Order, the Commission modernized and revised the accident regulations for electric, gas, and water utilities. See id. at 7-25, Annex A (revising Section 57.11 for electric, Section 59.11 for gas service, and Section 65.2 for water service). However, we did not update the relevant section, 52 Pa. Code § 61.11, for steam utilities. Therefore, through this comprehensive rulemaking to modernize and update our steam heat distribution regulations, we proposed similar changes to Section 61.11, as currently exist in Sections 57.11, 59.11, and 65.2 of our regulations. Since IRRC approved these changes in 2011, the Commission sought in the Proposed Rulemaking Order comments on whether it should apply similar proposed revisions in our steam heat regulations.
We inserted the word ''steam'' in the existing Section 61.11(a) for clarity purposes. See Annex A, Section 61.11(a). We proposed revising Section 61.11(b)(2) regarding reportable accidents to reflect the existing language in the relevant electric, gas, and water regulations. We proposed revising Section 61.11(b)(3) to reflect the property damage provisions in Sections 57.11 and 59.11 of the electric and gas regulations. See Annex A, Section 61.11(a) (mirroring the $50,000 market value proper damage requirement). We proposed adding Section 61.11(b)(5) for steam facilities to mirror Section 59.11(b)(4) regarding the emergency shutdown of a liquefied natural gas facility. See Annex A, Section 61.11(b)(5). In 2011, we modernized our regulations to account for potential physical or cyber-attacks that cause an interruption of service or over $50,000 in damages, or both. Here, we proposed a similar provision for our steam regulations. See Annex A, Section 61.11(b)(6).
As in our existing electric, gas, and water regulations, we proposed an exception for reporting due to injuries suffered as a result of a motor vehicle accident with utility facilities unless a vehicle involved in the accident is owned by the utility or driven by a utility employee while on duty. See Annex A, Section 61.11(c).
The existing Section 61.11(c) provides for telegraphic reports. The term ''telegraph'' is antiquated and out of common parlance. In light of this and the fact that proposed Section 61.11(e) provides for written reports, we proposed deleting this section. Instead, we proposed requirements for telephone reports using similar language found in our electric, gas, and water regulations. See Annex A, Section 61.11(d).
As for written reports, we proposed adding similar requirements that are currently found in our existing electric, gas, and water regulations. Written reports will need to be made on the Form UCTA-8 within 30 days of the occurrence of a reportable accident. At a minimum, the accident report form will need to include: (1) the name of the steam utility; (2) the date of the reportable accident; (3) the date of the report; (4) the location of the reportable accident; (5) the name, age, residence, and occupation of injured or deceased persons; (6) a general description of the reportable accident; and (7) the name and telephone number of the reporting officer. See Annex A, Section 61.11(e).
In the same vein as our electric, gas, and water regulations, in this Section we proposed adding Section 61.11(f) providing for the availability of UCTA-8 forms on the Commission's web site and Section 61.11(g) explaining that reporting requirements may not be limited to the requirements of Section 61.11. See Annex A, Section 61.11(f)-(g); see also 52 Pa. Code §§ 57.11(f)-(g), 59.11(f)-(g), 65.2(f)-(g).
Comments from VEPI and Resolution
VEPI suggests changing the use of ''may'' in Section 61.11(c) to ''shall'' so that the steam utility clearly understands what type of injuries do not need to be reported. We agree with VEPI's suggestion and have made the appropriate changes in new Annex A. We have also changed the word ''may'' to ''shall'' in other appropriate sections of the new Annex A.
Section 61.12 Interruptions of service
Here, we proposed inserting the word ''steam'' in the existing Section 61.12(a) for clarity purposes. See Annex A, Section 61.12(a). Section 61.12 is very similar to the gas regulation in Section 59.12, except that Section 59.12 does not require records of interruptions of service be kept for six years. However, Section 59.45 in our gas regulations requires a natural gas distribution utility to keep records of service interruptions for five years. See 52 Pa. Code § 59.45 (item number 65). Therefore, we requested comments as to the appropriate duration for recordkeeping of a steam utility regarding interruptions of service.
Comments from VEPI and Resolution
VEPI suggests that maintaining records for 3 years is more reasonable than 6 years, and VEPI notes that 3 years is consistent with the record-keeping requirements under Section 61.42 and Section 61.49. We agree in part with VEPI's suggestion and have made the appropriate change. Specifically, we have changed the record retention requirement to 5 years.
New Safety Requirements Regulations: Sections 61.41—61.53
The Commission modeled some of these proposed safety regulations on New York's existing regulations, but made adjustments to reflect the current best practices and modern standards in the existing steam distribution industry in the Commonwealth. See 16 NYCRR 420.1—420.15.
Section 61.41 Purpose and Policy
In Section 61.41(a), the Commission explains the purpose of these steam distribution safety regulations: ''to prescribe the minimum safety requirements for the design, fabrication, installation, inspection, testing, operation, and maintenance of steam distribution systems in the Commonwealth of Pennsylvania.'' See Annex A, Section 61.41(a); see 61.41(b) (requiring steam public utilities to adhere to the requirements of this section). Section 61.41(c) clearly provides the Commission with the power to inspect the distribution systems of steam utilities. Section 61.41(d) explains that this section does not apply to the generation, production, or piping steam downstream of the customer's property line.
Comments from IRRC and Resolution
IRRC notes that based on the definitions in Section 61.1, the termination point may be the property line or a point provided by contract. Accordingly, IRRC suggests that the Commission should either add a definition of ''termination point'' or amend this subsection to include the possibility that the point is described in contract. To address IRRC's concern, we have added a definition for ''Customer's Piping'' in Section 61.1 which both clarifies and eliminates an additional definition or amendment.
Section 61.42 Safety and compliance with standard code
Similar to the Commission's gas regulations at 52 Pa. Code § 59.33, we proposed Section 61.42(a) explaining that a steam 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 equipment or facilities.'' See Annex A, Section 61.42(a). In order to ensure that steam companies keep up with best practices and the most updated and applicable standards of the American Society of Mechanical Engineers (ASME), we proposed Section 61.42(b) requiring steam utilities to comply with standard code. See Annex A, Section 61.42(b). Here, we also proposed providing the Commission with the discretion to determine whether a particular redesign, repair, modification, or replacement of a facility constitutes a new facility subject to these regulations and thus subject to the latest ASME standards. Annex A, Section 61.42(b). Generally, if a grandfathered facility is substantially redesigned, repaired, or replaced, we required the updated facility to conform to the latest governing code standards. The steam utilities may informally consult with Commission staff as to any questions on what may or may not constitute a redesign, repair, replacement, or modification.
Here, we also required steam utilities to adhere to the Underground Utility Line Protection Act (''PA One Call'' or ''Act 287''). See 73 P.S. § 176; see Annex A, Section 61.42(c). PA One Call requires underground facility owners, including public utilities, to become members of the One Call System, a Commonwealth-wide communication system that provides a single nationwide toll-free telephone number or 811 number for excavators, designers, or other persons covered by Act 287 to call facility owners and notify them of their intent to perform excavation, demolition, or similar work. 73 P.S. §§ 176-177.
Similar to our gas regulations, 52 Pa. Code § 59.33(d), we proposed Section 61.42(d), explaining that a steam utility shall be subject to enforcement and inspections of its facilities, books, and records. As in the gas regulations at 52 Pa. Code § 59.33(e), we proposed Section 61.42(e), requiring a steam utility to keep adequate records to assure compliance with this subsection. We proposed this recordkeeping requirement for three years. See Annex A, Section 61.42(e).
Comments from IRRC and Resolution
As to subsection (a), IRRC suggests deleting the word ''every.'' As to subsection (b), IRRC seeks clarification as to the standards for existing facilities and the possible difficulty for utility compliance. In subsection (c) and (e) respectively, IRRC suggests that the reference to ''PA One Call'' is premature as the legislation for PUC enforcement is still pending in the state legislature and that the term ''adequate records for compliance'' is vague.
We agree with IRRC in part. First, we have deleted the word ''every'' from subsection (a). As to the standards for existing facilities, we will rely upon the applicable standards of the ASME. As to the vagueness of the term ''adequate records for compliance,'' we are confident that the small number of steam utilities combined with their expressed willingness of cooperation will enable the Commission to obtain the necessary records for determining compliance.
We have also added a subsection (f) to define the applicability of this regulation. As to the reference to ''PA One Call,'' we note that at this point, there is proposed legislation that may be enacted before the effective date of this regulation. Notwithstanding, we do not believe it is a prerequisite for the Commission to have enforcement responsibility for ''PA One Call.'' Finally, we point out that we have been working very closely with the NRG Companies and VEPI before and after the drafting of these regulations and it is the firm opinion of the NRG Companies and VEPI that specifying the records for compliance at this point would not be in the Commission's best interest.
Section 61.43 Notification of major construction
Similar to the Commission's gas regulations at 52 Pa. Code § 59.38, we proposed requiring the steam utility to notify the Commission and the Commission's Gas Safety Division of proposed major construction, reconstruction, or maintenance at least 30 days in advance of commencing work. Similar to the gas regulation, we defined major work as a single project involving more than $300,000 in expenses or more than 10% of the cost of the utility's plant in service, whichever is less. See Annex A, Section 61.43. We sought comment on whether this is an appropriate definition for major construction. Similar to the gas regulation, we proposed requiring the notification of construction to include (1) description and location of proposed work; (2) type of facility involved; (3) estimated starting date; (4) estimated completion date; (5) design pressure; (6) estimated cost; (7) name and address of reporting steam company;( 8) contact information for person in charge of the project; and (9) notification to the Commission of the completion date. Annex A, Section 61.43; see also 52 Pa. Code § 59.38.
Comment from IRRC and Resolution
IRRC suggests that Paragraph 9 ''Notification to the Commission of the completion date'' should be restated. We agree with IRRC and have eliminated Paragraph 9 and created a subsection (B) which provides the necessary clarification. With consultation and agreement from the NRG Companies and VEPI, we have created a $250,000 threshold for notification of major construction.
Section 61.44 Operating and maintenance plan
In Section 61.44, we proposed requiring steam utilities to establish and file with the Secretary of the Commission and the Gas Safety Division a detailed, written operating and maintenance plan. See Annex A, Section 61.44(a). We listed the minimal requirements for this plan, including (1) detailed instructions for employees, (2) welding procedures, (3) procedures for reporting and investigating steam leaks, (4) procedures to correct deficiencies, (5) procedures for facility surveillance, (6) a list of qualified utility employees, and (7) steam distribution system turn-on procedures. See Annex A, Section 61.44(b). We required the steam utility to adhere to these operating procedures and maintenance plan filed with the Commission. See Annex A, Section 61.44(c). Revisions to the plan would need to be submitted at least 30 days in advance of the effective date of those revisions. See Annex A, Section 61.44(a).
Comments from VEPI and IRRC and Resolution
VEPI and IRRC both requests that the Commission specify and exact date by which the plan is required to be in place and VEPI and IRRC both request clarification as to whether ''the plan'' in the last sentence of Subsection (a) refers to the original plan, or if it is referring to subsequently revised plans. We have provided an exact date and the necessary clarification.
Section 61.45 Security planning and emergency contact list
At the outset, we noted that Chapter 101 of our regulations requires a steam utility to develop and maintain four written plans: (1) physical security plan, (2) cyber security plan, (3) emergency response plan, and (4) business continuity plan. 52 Pa. Code §§ 101.2—101.3. Therefore, we noted in this section that steam utilities shall adhere to the requirements of Chapter 101. See Annex A, Section 61.45(a).
Under Chapter 101, an emergency response plan must, at a minimum, include: (1) identification and assessment of the problem, (2) mitigation of the problem in a coordinated, timely, and effective manner, and (3) notification to appropriate emergency services and officials. 52 Pa. Code § 101.3(a)(4)(i)—(iii). Additionally, within its Chapter 101 emergency response plan, we proposed requiring a steam utility to also specifically provide procedures to establish: (1) the availability of necessary personnel, equipment, tools, and materials at the scene of an emergency, (2) an action plan that protects people first and then property, (3) emergency facility shutdown protocols, (4) safety protocols, and (5) safety service main or outage restoration protocols. See Annex A, Section 61.45(b).
We also required a steam utility to file with the Commission and the Gas Safety Division each January a list of the utility's responsible officials for contact during an emergency. See Annex A, Section 61.45(c). The steam utility would serve this list on affected municipalities and immediately report revisions of this list to those municipalities and to the Commission. See id.
Comments from IRRC and Resolution
IRRC questions the need to require annual reporting of the list of the utility's responsible officials to both the Commission's Secretary and the Gas Safety Division. IRRC also questions the filing of any revisions to the list on just the Gas Safety Division. While we appreciate IRRC's concern, we will respectfully continue our long-standing practice of dual reporting which has been agreed to by both the NRG Companies and VEPI. As to the revisions, we prefer that the revisions be reported solely to the now Pipeline Safety Division, which has an immediate need for updated information.
Section 61.46 Customer education and information program
We proposed requiring a steam utility to maintain customer and education programs through the use of media that sufficiently and comprehensively reaches, to the extent possible, all customers in the particular service territory. See Annex A, Section 61.46(a)-(b). We required a steam utility to file with the Commission and Gas Safety Division each January a current description of its customer education and information program, including the means of implementation and any samples of descriptive literature and other educational aids. See Annex A, Section 61.46(c).
Comment from IRRC and Resolution
IRRC suggests that this requirement is vague and should be replaced with a specific standard. As stated previously, the Commission has worked closely with the NRG Companies and VEPI. Both have indicated agreement with the requirement and all agree that flexibility is crucial. If experience indicates that specific standards in the form of binding regulations are required, we can revisit this issue in the future.
Section 61.47 Employee training
Here, we proposed requiring every employee and supervisor of a steam utility to receive and complete annual training at sufficiently progressive levels to ensure the safe implementation of all the procedures required in this subchapter on Safety Requirements. See Annex A, Sections 61.47(a). Before on-the-job training in field operations, new employees shall receive basic classroom training. See Annex A, Section 61.47(b).
Comments from IRRC and Resolution
IRRC has raised concerns regarding employee training. According to IRRC, Subsection (a) is vague regarding the training progression level. IRRC also is concerned about the subjects in which employees and supervisors must receive annual training. Finally, IRRC questions whether it is reasonable and appropriate for all employees in the operations, maintenance and testing to receive training at all progression levels.
In general, it is Commission's position that each employee is required to be qualified on the specific tasks as defined in the steam utilities comprehensive Operator Qualification Program. The level of training that the employees receive must qualify them to perform cover tasks that they are assigned. However, in response to IRRC's concern, we have clarified the category of new employees that should receive basic classroom training.
Section 61.48 Periodic inspections
In this section, we proposed requiring a steam utility to inspect steam traps and piping assemblies for general condition at least three times each calendar year, as we understand that this would be practicable and in alignment with best practices. We sought public comment on whether this requirement is sufficient.
Similar to the New York regulations, we also proposed mandatory checking of blow-off valves for operability immediately prior to closing each associated main valve during a scheduled shutdown of a section of the steam distribution pipeline system. We also proposed inspections of accessible expansion joints at least twice annually. See Annex A, Section 61.48(b)-(c); see 16 NYCRR 420.8(b)-(c).
We also proposed annual inspections of service valves and manholes owned by the steam utility. See Annex A, Section 61.48(d)-(e). Finally, we proposed requiring the inspection and testing of remote system pressure indicating devices every two years. See Annex A, Section 61.48(f).
Comments from NRG Companies and IRRC and Resolution
Both the NRG Companies and IRRC expressed concerns with the requirement of three inspections per year. The NRG Companies and IRRC both suggest one inspection of the steam traps and piping assemblies. We agree with the NRG Companies and IRRC and have changed the inspection requirement to once a year.
Section 61.49 Records
Here, we required a steam utility to maintain records documenting inspections, maintenance, tests, and all other matters required by this chapter for at least three years. Those records would be kept on file and readily available to Commission staff. See Annex A, Section 61.49. This provision is similar to the Commission regulation governing gas safety. See 52 Pa. Code § 59.33(e).
In light of Section 61.12 of our existing regulations (requiring service interruption records for six years) and proposed Section 61.42(e) (requiring records demonstrating compliance with safety codes for three years), we sought comment on whether any of these recordkeeping requirements are duplicative or whether we need to break out and specify different recordkeeping requirements for different subject areas, as in our gas regulations. See 52 Pa. Code § 59.45 (Preservation of records).
Comments from IRRC and Resolution
IRRC has raised two questions: Is the steam utility required to keep an extra copy of its records and is the steam utility required to have offices in Pennsylvania? We agree with IRRC's suggestion and have deleted both the reference to ''copies'' and ''in the Commonwealth of Pennsylvania.'' In response to IRRC's subsequent comment concerning record retention, we will change the time frame for record retention to 5 years throughout the regulation.
Section 61.50 Welding—qualification and nondestructive testing
In this section, we required the performance of welding in accordance with the latest standards of the American Society of Mechanical Engineers. See Annex A, Section 61.50(a). We required nondestructive testing of inaccessible field welds and new pipeline testing at system pressure. See Annex A, Section 61.50(b). New construction pipelines shall be pressure tested to 1.5 times the maximum allowable operating pressure. See Annex A, Section 61.50(c). Ten percent of all field welds on existing steam pipeline facilities shall be subject to random nondestructive testing. The results of this testing would determine the test rates in future years, decreasing or increasing the test rate based on results of the prior year. See Annex A, Section 61.50(d).
Comments from the NRG Companies, VEPI and IRRC
Noting the comments from the NRG Companies and VEPI, IRRC suggests that the Commission should review those comments and clarify the regulation to clearly state what types of testing are acceptable. IRRC also recommended that the Commission should explain why the testing required by the regulation is the best alternative.
After further consultation with the NRG Companies and VEPI, we have clarified this subsection by deleting the pressure testing requirement for new construction pipelines. We have also clarified the requirement for field welds and we have added a limitation on pressure tests.
Section 61.51 Steam leaks and steam emergency reports
Since emergency leaks ''require an immediate response to protect life and property'' we proposed requiring that those leaks ''shall be worked continuously until repairs are completed or until the condition is no longer hazardous.'' See Annex A, Section 61.51(a). We explained that emergency leaks are those that could cause property damage or personal injury or any leak which, in the judgment of the operating personnel at the scene, is regarded as potentially hazardous. See id. Notably, emergency leaks could be caused by forces outside of the steam distribution system, such as water main breaks, flooding, earthquakes, or other serious weather events.
In order to discern emergency leaks from nonemergency leaks, we explained that nonemergency leaks are those that are ''not immediately hazardous at the time of discovery and can be reasonably expected to remain that way.'' See Annex A, Section 61.51(b). Therefore, we proposed that those nonemergency leaks need not be confronted immediately, but must be reexamined within six months from the date of discovery, and repaired within a reasonable time. See Annex A, Section 61.51(b). We understand that many steam leaks are very minor and nonhazardous, similar to a faucet of dripping water. Unlike minor gas leaks, which present imminent danger, minor steam leaks may not necessarily require immediate confrontation and repair. However, we stressed to the steam utilities that these minor leaks shall be recorded, confronted, and repaired within a reasonable time, as even minor leaks, nonhazardous at discovery, could eventually become more hazardous over time. See Annex A, Section 61.51(c). Therefore, we proposed requiring a steam utility to identify all leaks, compile a written report of each emergency and nonemergency steam leak, and keep an event log on record. See Annex A, Section 61.51(c)—(e). The event log shall contain (1) the location of leak or emergency; (2) the time the report is first received; (3) description as to type of leak or emergency; (4) the time personnel are first dispatched to location; (5) the time of arrival of personnel at location; and (6) the times of dispatch and arrival of any additional personnel called to the location. See Annex A, Section 61.51(e).
Finally, we proposed that a steam utility shall have available for inspection by the Commission's Gas Safety Division, on or before the 16th day of each calendar month, a summary analysis of its performance in responding to reports of steam leaks and emergencies. See Annex A, Section 61.51(f).
Comments from the NRG Companies, VEPI and IRRC
In reviewing Section 61.44(4), which relates to an operating and maintenance plan, and subsection (b), which requires non-emergency leaks to be re-examined within 6 months from the date of discovery and reparable within a reasonable time, IRRC raises a concern as to whether these are two different standards for one type of leak? IRRC also requests an explanation as to what constitutes a ''summary analysis.'' The NRG Companies suggests that the date of the 16th of the month for the summary analysis of steam leak reports be changed to the end of the month to better coincide with normal company reporting procedures. VEPI raises a question concerning the extent of vaporization.
In response to IRRC's concern, we note that Section 61.44 specifically relates to required written operating and maintenance plans. As to the content of the'' summary analysis'' of the steam utilities performance in responding to reports of steam leaks and emergencies, we are expecting the steam utility to provide basic information that enables the Commission to access their overall performance. Simply stated, we are requesting a summary of the steam utilities' performance in responding to reports of steam leaks and emergencies. However, for clarification, we have deleted the word ''analysis'' and in response to a subsequent comment from IRRC concerning the time frame for record retention, we have added a 5-year requirement.
As to the NRG Companies and VEPI concerns, we have changed the date for the summary analysis from the 16th of the month to the end of the month and we have added a subsection that addresses vaporization.
Section 61.52 Facility failure investigation
Similar to New York's regulation, 16 NYCRR 420.14, we proposed requiring each steam utility to establish procedures to analyze each failure that causes injury or damage in order to determine the cause and minimize the possibility of recurrence. See Annex A, Section 61.52(a). These procedures would need to provide for the selection of samples of the failed facility or equipment for laboratory examination, as necessary. See id. The steam utility shall fully cooperate with Commission staff and any necessary independent consultants regarding the testing or surveying of any facilities or equipment deemed potentially attributable to the facility failure or accident. See Annex A, Section 61.52(b). During meetings between PUC staff and steam company representatives, the question of what constitutes a ''facility failure'' arose. We found consensus in determining that a ''facility failure occurs when the facility fails to perform the function it was designed for.'' See Annex A, Section 61.52(c).
Comment from the NRG Companies and Resolution
In response to a concern from the NRG Companies, we have added a subsection which addresses the qualifications of the independent consultant.
Section 61.53 Asbestos control
Many old buildings and facilities in the Commonwealth still contain asbestos. Therefore, we proposed requiring a steam utility to have procedures to safely manage and abate asbestos materials from all accessible manholes, vaults, and other areas that contain steam facilities. See Annex A, Section 61.53(a). We required the steam utility to have emergency procedures to control and eliminate asbestos-contaminated debris resulting from the failure of any steam pipeline or facility. See Annex A, Section 61.53(b).
The public health threat of asbestos is well-known and well-documented. Accordingly, we required a steam utility to have a program that maintains in safe condition all asbestos materials on all exposed piping and fittings in the steam distribution system and the gradual elimination of all asbestos materials to the extent practicable and feasible. See Annex A, Section 61.53(c). We proposed requiring a steam utility ''to eliminate all asbestos materials to the extent practicable and feasible.'' See Annex A, Section 61.53(c). We sought further public comment as to whether this proposed language best serves the public interest.
Finally, we emphasized that the procedures regarding asbestos control must comply with all applicable rules and regulations regarding the removal, handling, and disposal of asbestos materials. See Annex A, Section 61.53(d).
Comment from IRRC and Resolution
In response to IRRC's jurisdictional concern, we have deleted this subsection.
Service Outage Requirements: Chapter 67
Section 67.1 General Provisions
On September 23, 2011, the Commission entered a Final Rulemaking Order pertaining to public utilities' service outage response and restoration practices. See Docket L-2009-2104274 (Final Rulemaking Order entered Sep. 23, 2011); see 14 Pa.B. 4511 (effective Jan. 7, 2012). Among other things, the Final Rulemaking Order amended the Commission's service outages regulations in Chapter 67 of the Pennsylvania Code. Chapter 67 expressly applies to electric, gas, water, and telephone utilities, but does not expressly apply to steam utilities. See 52 Pa. Code § 67.1(a). The Commission also sought comment on whether Chapter 67 should apply to the service outage regulations of jurisdictional steam utilities. We have added a sentence which states that steam utilities with fewer than 50 customers shall provide such notice when at least 10% of total customers experience such an interruption. In addition, the Commission adds the word steam in four places in Section 67.1 to make the section's application to steam heat utilities clear. See Annex A, Section 67.1.
Regulatory Review
Under section 5(a) of the Regulatory Review Act (71 P.S. § 745.5(a)), on January 27, 2016, the Commission submitted a copy of the notice of proposed rulemaking, published at 46 Pa.B. 658 (February 6, 2016), to IRRC and the Chairpersons of the House Consumer Affairs Committee and the Senate Consumer Protection and Professional Licensure Committee for review and comment.
Under section 5(c) of the Regulatory Review Act, the Commission shall submit to IRRC and the House and Senate Committees copies of comments received during the public comment period, as well as other documents when requested. In preparing the final-form rulemaking, the Commission has considered all comments from IRRC and the public.
Under section 5.1(j.2) of the Regulatory Review Act (71 P.S. § 745.5a(j.2)), on October 11, 2017, the final-form rulemaking was deemed approved by the House and Senate Committees. Under section 5.1(e) of the Regulatory Review Act, IRRC met on October 12, 2017, and approved the final-form rulemaking.
Conclusion
Accordingly, under 66 Pa.C.S. §§ 501 and 1501; sections 201 and 202 of the act of July 31, 1968 (P.L. 769, No. 240) (45 P.S. §§ 1201 and 1202), and the regulations promulgated thereunder at 1 Pa.
