Federal Rulemaking Process

Significant Rule

PHMSA Federal Register

Non‐Significant Rule

Significant rules must go through the Office of the Secretary of Transportation (OST) and the Office of Management & Budget (OMB).  OMB determines What Rules Are Significant

Page 7: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

What makes a rule Significant?

• Have an annual effect on the economy of $100 million or more

• Create a serious inconsistency or with another agency• Materially alter budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or 

• Raise novel legal or policy issues arising out of legal mandates, the President’s priorities, or the principles set forth in this Executive order.

Reducing Regulation and Controlling Regulatory Costs (Two for one order)

“Unless prohibited by law, whenever an executive department or agency… promulgates a new regulation, it shall identify at least two existing regulations to be 

repealed.” 

“… the total incremental cost of all new regulations, including repealed regulations, to be finalized this 

year shall be no greater than zero.”

Page 11: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

11

Reducing Regulation & Controlling Regulatory Costs

•Only applicable to significant rulemakings.•Exempt: Rules required by statute or court order; Independent agencies (but encouraged to follow)

•An agency can bank deregulatory actions for later use or trade across the whole department.

•With permission from OMB, one agency can use a banked deregulatory action created by another department. 

•Expect: More scrutiny of “significant rules”, longer timelines, more “non‐significant rulemakings”.

Page 12: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

Comprehensive Plan for Reorganizing the Executive Branch

•Federal agencies to send OMB (by 9/17) a reorganization plan that describes how “to reorganize governmental functions and eliminate unnecessary agencies…, components of agencies, and agency programs.”  

•OMB to invite “the public to suggest improvements in the organization and functioning of the executive branch.” 

•OMB to develop a plan to reorganize executive branch, considering public comments and “relevant factors”

Page 13: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

13

Comprehensive Plan for Reorganizing the Executive Branch – Relevant Factors

•Whether the functions are appropriate for Federal Government or would be better left to State/local governments or private sector; 

•Whether some or all of the functions or administrative capabilities are redundant; 

•Whether the costs of operating the agency, office or program “are justified by the public benefits”; and 

•The costs of shutting down or merging agencies, offices or programs, including “addressing the equities of affected agency staff.”

First, a few of AGA’s Pipeline SafetyMessages

Page 32: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

There is nothing more important to America’s natural gas utilities than the safety of the customers we serve and the communities in which we operate.

“AGA and its member companies are committed to promoting positive safety cultures among their employees throughout the natural gas distribution industry. All employees, as well as contractors and suppliers providing services to AGA members, are expected to place the highest priority on employee, customer, public and pipeline safety.”— Excerpt from AGA SafetyCulture Statement

Page 33: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

2.5Million miles of 

pipeline

Safely Transported Across the CountryNatural gas pipelines:• transport approximately 

one‐fourth of the energy consumed in the U.S.

• the safest form of energy delivery in the country

Natural gas is delivered to customers through a 2.5 million‐mile underground pipeline system. This includes 2.2 million miles of local utility distribution pipelines and 300,000 miles of transmission pipelines that stretch across the country.

Page 34: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

Modernizing InfrastructureAll natural gas utilities upgrade and modernize their infrastructure through risk‐based integrity management programs.

41 states including the District of Columbia have specific rate mechanisms that foster accelerated replacement of pipelines  no longer fit for service.

41States

• Work with governors, legislators and state regulators to develop innovative models for replacing pipe no longer fit for service 

• Enhances the safety and reliability of our pipeline network

• Provides natural gas access to homes and businesses across the nation

• $22 billion spend annually to help enhance the safety of natural gas distribution and transmission systems.

Page 35: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

• Pockets of this country do not have access to natural gas

• Homes, businesses, factories and electric generators have the capacity to efficiently utilize more natural gas

• Gas utilities are working with energy planners, regulators and policymakers to bring the comfort and savings of natural gas to these new customers.

Pipelines Bring Opportunity

An interstate natural gas pipeline construction or expansion project takes an average of about three years from the time it is first announced until the new pipe is placed in service.

Page 36: Pipeline Safety Update - energypa.org Event Gas/Presentation... · Pipeline Safety Update Christina Sames Vice President, Operations & Engineering Services ... Welding Procedures:

Regulatory ExpectationsPHMSA and State Regulators expect operators to:• Go above and beyond regulations

• Where possible, PHMSA will publicly support company efforts beyond regulations to improve pipeline safety. 

• Fully embrace integrity management• Know Your System!

• Base decisions on sound data• Confirm existing data; find ways to address data gaps

• Embrace Pipeline Safety Management Systems• Plan – Do – Check ‐ Act

Corrosion Control:  PHMSA should extend deadline for post‐construction/excavation coating surveys or at least provide a justification for the proposed 3‐month timeframe.‐ Industry Comments: 

‐ Remove prescriptive requirements to Subpart I & keep requirements performance based. 

‐ Remove duplication (i.e., §192.478(c) & §192.477).‐ Operators should have 1‐year to perform remedial action on deficiencies found during “indirect assessments” evaluating “adequate corrosion control measures.”

‐ Internal Corrosion Incident Data provided to clarify impact this threat has on on‐shore gas transmission pipelines. Operator case study provided to explain costs associated with PHMSA’s proposal for internal corrosion control monitoring.

‐ Appendix D: Criteria for Cathodic Protection & Determination Measurements should reference full Section 6 of NACE SP0169

Safety of Gas Transmission & Gathering Lines RuleOutputs from GPAC Meeting #1: For Further Discussion

Corrosion Preventive & Mitigative Measures‐ GPAC Discussion: 

‐ Discussion on §192.935(f) & (g) on Internal Corrosion & External Corrosion P&M Measures was limited during the first meeting. It will be revisited during Meeting 2. 

‐ Industry Comments: ‐ Much of the proposed additions to §192.935(f) & (g) are duplicative of sections in Subpart I that are applicable to all pipelines. PHMSA should remove these duplicative requirements.
