## 8. Pipeline Safety: Safety of Underground Natural Gas Storage Facilities

**Citation:** 85 FR 8104  
**Type / status:** rulemaking / historical  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** 2020-03-13 / 2020-02-12

The Pipeline and Hazardous Materials Safety Administration is publishing this final rule to amend its minimum safety standards for underground natural gas storage facilities (UNGSFs). On December 19, 2016, PHMSA issued an interim final rule (IFR) establishing regulations in response to the 2015 Aliso Canyon incident and the subsequent mandate in section 12 of the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016. The IFR incorporated by reference two American Petroleum Institute (API) Recommended Practices (RPs): API RP 1170, "Design and Operation of Solution-mined Salt Caverns Used for Natural Gas Storage" (First Edition, July 2015); and API RP 1171, "Functional Integrity of Natural Gas Storage in Depleted Hydrocarbon Reservoirs and Aquifer Reservoirs" (First Edition, September 2015). The IFR required each provision in the API RPs to apply as mandatory (i.e., each "should" statement would apply as a "shall") unless an operator provides written justification for not implementing the practice, including an explanation for why it is impracticable and not necessary for safety. Based on the comments received to the IFR and a petition for reconsideration, PHMSA has determined that the RPs, as originally published, will provide PHMSA with a stronger basis upon which to base enforcement than the IFR. This final rule also addresses recommendations from commenters and a petition for reconsideration of the IFR by modifying compliance timelines, revising the definition of a UNGSF, clarifying the states' regulatory role, reducing recordkeeping and reporting requirements, formalizing integrity management practices, and adding risk management requirements for solution-mined salt caverns.

## 19. Alcohol Misuse Prevention Program; Rule DEPARTMENT OF TRANSPORTATION

**Citation:** Not assigned  
**Type / status:** rulemaking / historical  
**Agency:** Office of the Federal Register  
**Effective / published:** 1994-03-17 / 1994-02-15

This final rule sets forth regulations requiring operators of gas, hazardous liquid and carbon dioxide pipelines and liquefied natural gas (LNG) facilities subject to the pipeline safety regulations to implement alcohol misuse prevention programs for employees who perform safety-sensitive functions. This final rule is consistent with the alcohol rules of other operating administrations (OAs) published elsewhere in today's Federal Register, except that RSPA is not requiring pre-employment or random testing. The final rule requires only post-accident, reasonable suspicion, return-to-duty, and follow-up testing. This rule requires operators to remove from safety-sensitive functions employees who engage in prohibited alcohol conduct, and not permit them to return to those functions until specific requirements are met. Operators must provide covered employees with written materials that specifically identify the employees covered by the rule, explain the requirements of the rule, and establish the consequences of engaging in prohibited conduct. Operators must maintain records concerning their programs and report data regarding employee alcohol misuse to RSPA annually. The rules are intended to ensure an alcohol- free workplace, and increase the overall safety of pipeline operations.

## 28. Pipeline Safety: Integrity Management Program for Gas Distribution Pipelines

**Citation:** 74 FR 63906  
**Type / status:** rulemaking / historical  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** 2010-02-02 / 2009-12-04

PHMSA is amending the Federal Pipeline Safety Regulations to require operators of gas distribution pipelines to develop and implement integrity management (IM) programs. The purpose of these programs is to enhance safety by identifying and reducing pipeline integrity risks. The IM programs required by this rule are similar to those required for gas transmission pipelines, but tailored to reflect the differences in and among distribution pipelines. Based on the required risk assessments and enhanced controls, the rule also allows for risk-based adjustment of prescribed intervals for leak detection surveys and other fixed-interval requirements in the agency's existing regulations for gas distribution pipelines. To further minimize regulatory burdens, the rule establishes simpler requirements for master meter and small liquefied petroleum gas (LPG) operators, reflecting the relatively lower risk of these small pipelines. In accordance with Federal law, the rule also requires operators to install excess flow valves on new and replaced residential service lines, subject to feasibility criteria outlined in the rule. This final rule addresses statutory mandates and recommendations from the DOT's Office of the Inspector General (OIG) and stakeholder groups.

## 37. Pipeline Safety: Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences

**Citation:** 80 FR 41460  
**Type / status:** rulemaking / proposed  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** Not stated / 2015-07-15

Excess Flow Valves (EFVs), which are safety devices installed on natural gas pipelines to reduce the risk of accidents, are currently required for new or replaced gas service lines servicing single-family residences (SFR). PHMSA is proposing to make changes to part 192 to expand this requirement to include new or replaced branched service lines servicing SFRs, multi-family residences, and small commercial entities consuming gas volumes not exceeding 1,000 Standard Cubic Feet per Hour (SCFH). PHMSA is also proposing to require the use of manual service line shut-off valve (e.g., curb valves) for new or replaced service lines with meter capacities exceeding 1,000 SCFH. Finally, PHMSA is proposing that operators notify customers of their right to request installation of an EFV on service lines that are not being newly installed or replaced. PHMSA is proposing to delegate the question of who bears the cost of installing EFVs to service lines that are not being newly installed or replaced to the operator, customer, and the appropriate State regulatory agency.

## 43. Pipeline Safety: Expanding the Use of Excess Flow Valves in Gas Distribution Systems to Applications Other Than Single-Family Residences

**Citation:** 81 FR 70987  
**Type / status:** rulemaking / historical  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** 2017-04-14 / 2016-10-14

Excess flow valves (EFV), which are safety devices installed on natural gas distribution pipelines to reduce the risk of accidents, are currently required for new or replaced gas service lines servicing single-family residences (SFR), as that phrase is defined in 49 CFR 192.383(a). This final rule makes changes to part 192 to expand this requirement to include new or replaced branched service lines servicing SFRs, multifamily residences, and small commercial entities consuming gas volumes not exceeding 1,000 Standard Cubic Feet per Hour (SCFH). PHMSA is also amending part 192 to require the use of either manual service line shut-off valves (e.g., curb valves) or EFVs, if appropriate, for new or replaced service lines with meter capacities exceeding 1,000 SCFH. Lastly, this final rule requires operators to notify customers of their right to request installation of an EFV on service lines that are not being newly installed or replaced. PHMSA has left the question of who bears the cost of installing EFVs on service lines not being newly installed or replaced to the operator's rate- setter.

## 50. Pipeline Safety: Integrity Management Program for Gas Distribution Pipelines

**Citation:** 73 FR 36015  
**Type / status:** rulemaking / proposed  
**Agency:** Pipeline and Hazardous Materials Safety Administration  
**Effective / published:** Not stated / 2008-06-25

PHMSA proposes to amend the Federal Pipeline Safety Regulations to require operators of gas distribution pipelines to develop and implement integrity management (IM) programs. The purpose of these programs is to enhance safety by identifying and reducing pipeline integrity risks. The IM programs required by the proposed rule would be similar to those currently required for gas transmission pipelines, but tailored to reflect the differences in and among distribution systems. In accordance with Federal law, the proposed rule would require operators to install excess flow valves on certain new and replaced residential service lines, subject to feasibility criteria outlined in the rule. Based on the required risk assessments and enhanced controls, the proposed rule also would establish procedures and standards permitting risk-based adjustment of prescribed intervals for leak detection surveys and other fixed-interval requirements in the agency's existing regulations for gas distribution pipelines. To further minimize regulatory burdens, the proposed rule would establish simpler requirements for master meter and liquefied petroleum gas (LPG) operators, reflecting the relatively lower risk of these small pipeline systems. This proposal also addresses statutory mandates and recommendations from the DOT's Office of the Inspector General (OIG) and stakeholder groups.
