PHMSA Final Rule on Expanding Natural Gas Transportation in Plastic Pipelines

U.S. DOT Announces Final Rule to Enhance Public Safety by Expanding Natural Gas Transportation in Plastic Pipelines

WASHINGTON – The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) today announced the issuance of a Final Rule that amends the Federal Pipeline Safety Regulations for plastic piping systems used in the transportation of natural or other gas. The updates in the final rule are intended to improve safety, allow for the expanded use of plastic pipe products in the transportation of natural or other gas, and allow or require the use of certain materials and practices.

“Advancements in plastic pipe design and manufacturing have resulted in products that are much safer today than they were 20 years ago,” said PHMSA Administrator Skip Elliott.  “These regulatory updates will significantly contribute to advancing public safety.”

The updates which are on public display today’s Federal Register take into consideration the changing technologies and issues affecting plastic pipe. They address concerns with installation and operational safety issues associated with plastic pipe, as observed by federal and state inspectors during routine field activities.  Additionally, several industry petitions received by PHMSA requested that the agency consider regulatory updates for plastic pipe that align with new innovations in manufacturing and design, as well as current best practices in plastic pipe installation.

The Final Rule will only apply to new, repaired, and replaced pipelines.  Regulatory updates include an increased design factor for polyethylene pipe; updated standards governing the use, maximum pressure limits, and diameters for pipelines made of polyamide 11 and 12 thermoplastics; new and expanded standards for the installation of plastic pipe to help mitigate contact with other underground utilities and structures; and several other installation and operational related provisions for plastic pipe and plastic pipe components.

As a result of the Final Rule’s updated design factor, the cost of materials to produce new pipe is estimated to be reduced by 10 percent, resulting in an annual material cost savings of approximately $32 million for transmission, gathering, and distribution operators.

This final rule is effective 60 days after the date of publication in the Federal Register.

The mission of the Pipeline and Hazardous Materials Safety Administration is to protect people and the environment by advancing the safe transportation of energy and other hazardous materials that are essential to our daily lives. PHMSA develops and enforces regulations for the safe operation of the nation’s 2.6 million mile pipeline transportation system and the nearly 1 million daily shipments of hazardous materials by land, sea, and air.

Canceled Tickets

After listening to our facility owners and operators, the Board of Directors approved the request from management to no longer charge a ticket fee for canceled outgoing transmissions. This change will take effect on January 1, 2019.

Safety Commission

What are home rule cities and how are they different?

Home rule cities by the Colorado constitution are cities that have the full right of self-government in local and municipal matters.  The larger home rule cities include Denver, Aurora, Pueblo, Colorado Springs, Fort Collins and Grand Junction. Home Rule cities can create their own safety commissions and can enforce the one-call law and imposed penalties for failure to comply with the law.

Will Colorado 811 provide data to the Safety Commission on an annual basis?

Yes.  Colorado 811 will annually provide a report as well as real time data for the Safety Commission’s work related to underground excavations and safety.

Can engineering companies give feedback to Safety Commission once in place?

Any person can provide feedback to the Safety Commission.

Will there be an entity responsible for holding stakeholders accountable under the new law?

Yes, the Colorado Safety Commission will have the responsibility to enforce the provisions of the law related to safe practices.  The Safety Commission can impose penalties for failure to comply with the law.  Home Rule cities may create a safety commission which also have the power to impose penalties for failure to comply with the law.  Facility owners and operators and excavators may bring civil actions for damage claims separate from the actions of the Safety Commission.

What cities are exempt from complying with the new Safety Commission requirements?

Only Home Rule cities are exempt from complying with the Safety Commission requirements but they must create their own safety commissions.

Regarding "home rule", if a municipality decides to invoke the home rule, doesn't this simply mean that the State cannot enforce any penalties against the municipality? Yet, can't the state still impose penalties against an excavator that has violated the state law against the municipality. i.e. damage caused due to no locate request? Or does this require the municipality to establish their own safety commission?
CO 811 is not in a position to offer an opinion regarding whether or not the State of Colorado can enforce penalties against a municipality under the new law.  The newly created Safety Commission will establish regulations that address this issue in cooperation with the Colorado Attorney General.CO 811 is not in a position to offer an opinion regarding whether or not the State of Colorado can enforce penalties against a municipality under the new law.  The newly created Safety Commission will establish regulations that address this issue in cooperation with the Colorado Attorney General.
There does not appear to be a way for an accused violator to dispute whether “costs of investigation and trial, including reasonable attorney’s fees” are warranted in an enforcement action under CRS 9-1.5-104.2.  Please confirm whether the intent of this legislation is to give the Safety Commission the right to seek enforcement costs/fees with NO opportunity for rebuttal by the accused violator.

Please defer to the Safety Commission once established.

Subsurface Utility Engineering (SUE)

Will there be a fee for engineering tickets that is different from the existing fee?

 The cost or fee for the outgoing transmission will remain the same for all members. The costs associated with an engineering locate request will be paid by the project owner.

What is ASCE 38 Standard?

ASCE Standards provide technical guidelines for promoting safety, reliability, productivity, and efficiency in civil engineering. For more information please visit https://www.fhwa.dot.gov/programadmin/asce.cfm

How will licensed professional engineers receive documentation related to Subsurface Utility Engineering Notifications?

Within 10 days of the notice provided, licensed professional engineers will receive documentation through the Positive Response system at Colorado 811.


Did the definition for exemptions change under the new law?

Yes, there are several modifications in the new law regarding exemptions they include: farmers/ranchers and new requirements for governmental agencies relative to road grading. Please note, there is no exemption for gravity fed systems. Although, these exemptions exist it is extremely dangerous to dig without first notifying Colorado 811 for the location of underground facilities.

What is the significance of defining “gravity-fed systems” in the law? Where is it referenced under the new legislation?

Gravity fed systems are now defined to clarify what information has to be provided in the event there is a request for a locate related to sub-surface utility engineering. The law defining this exemption is located at section 9-1.5-102 (3.4).

Are there new requirements regarding road grading?

Yes, there are new requirements regarding road grading. The Procedures Committee of Colorado 811 is currently devising specific procedures and guidelines that will be available within the next couple of months. (From law: ANNUAL ROAD MAINTENANCE THAT DOES NOT EXCEED SIX INCHES IN DEPTH CONDUCTED BY A GOVERNMENTAL AGENCY ON AN EXISTING UNPAVED ROAD, THE MARKING SHALL BE CONSIDERED VALID FOR UP TO ONE HUNDRED EIGHTY DAYS.)


Who is required to locate laterals in the public right-of-way?

 All underground facility owner/operators are responsible for the location of service laterals in the public right-of-way.

How will Colorado 811 provide documentation of the underground facilities in the form of hand written/ digital sketches or photography?

It is Colorado 811’s intent to provide the excavator this information through the Positive Response system.

Can an excavator put another excavator on his/her ticket? How many can you list on one ticket?

 Yes, an excavator requiring existing marked underground facilities to be exposed may list a single secondary excavator on its notice to Colorado 811.

It also says in (c) (1) (A) "When utilizing trenchless excavation methods, the excavator shall expose underground facilities and visually observe the safe crossing of marked underground facilities when requested to do so by the underground facility owner or operator or the government agency that issued a permit for the excavation." Question is, will this require a new positive response code?
A new positive response code will not be necessary as the facility owner will still be required to locate the area of excavation, if applicable. However, the facility owner and excavator must communicate to ensure that the visual crossing of marked underground facilities has been exercised.
How does 811 propose to address the CORA implications of 811 having all member facilities’ location details?

Colorado 811 is not subject to the Colorado Open Records Act. 

What, specifically, are the requirements and components of a damage prevention safety program as it would be developed and managed by a home rule entity that is choosing to opt out of the jurisdiction of the safety commission?

It is our understanding that a home rule entity electing to establish their own safety commission they will need to comply with the same rules as the State Safety Commission. Please defer to the Safety Commission once established.


Have excavators been informed of the changes to the 811 program? How is 811 communicating with them?

Colorado 811 has and is currently communicating with all stakeholders (including excavators) through the co811.org website, social media, email blasts, employee email signatures, 811 hold recording, and news articles in industry media outlets. The Colorado 811 Damage Prevention Liaisons inform excavators of the legislative changes at Damage Prevention Council Meeting and onsite presentations at excavator’s offices.

How is 811 communicating with Tier Two members during the transition?

Colorado 811 has and is currently communicating members through the co811.org website, social media, email blasts and letters that were sent via USPS on 8/06/18.

Colorado 811 will host member legislative meetings across the state starting late November. These meetings will be posted on the events section of our website and emailed to our membership email list. We welcome all Colorado 811 members to attend.

Can you provide additional information regarding when new facilities are required to be electronically locatable?

We believe all new facilities installed on or after January 1, 2019 must be locatable. For example, what about new developments in progress? All infrastructure must be locatable in the future. Are pipe replacements considered “new development” and subject to electronically locatable requirements? In our interpretation, yes. What about underground irrigation infrastructure located on agricultural land or shared between neighboring farms/ranches? Yes, anything within public access areas (public right-of-way).
