Dear Mr. Ledversis:
In a letter to the Pipeline and Hazardous Materials Safety Administration (PHMSA) dated
September 10, 2015, you requested an interpretation of 49 CFR Part 192. Specifically, you
asked whether a service line without an excess flow valve, which is damaged by excavation
activity, must be replaced with an excess flow valve under the requirement of§ 192.381 ( d).
Section 192.383(b) discusses the requirements for excess flow valve installation_ as follows:
§ 192.383 Excess flow valve installation.
(b) Installation required. An excess flow valve (EFV) installation
must comply with the performance standards in § 192.381. The
operator must install an EFV on any new or replaced service line
serving a single-family residence after February 12, 20 I 0, unless
one or more of the following conditions is present:
( 1) The service line does not operate at a pressure of 10 psig or
greater throughout the year;
(2) The operator has prior experience with contaminants in the gas
stream that could interfere with the EFV's operation or cause loss
of service to a residence;
(3) An EFV could interfere with necessary operation or
maintenance activities, such as blowing liquids from the line; or
( 4) An EFV meeting performance standards in § 192.3 81 is not
commercially available to the operator.
Where none of the conditions listed in § 192.383(b) are present, as discussed in your letter, a
replaced service line may require the installation of an excess flow valve. A replaced service
line is defined, under§ 192.383(a), as "a gas service line where the fitting that connects the
service line to the main is replaced or the piping connected to this fitting is replaced."
Furthermore, pursuant to § 192.383(b), the installation of an excess flow valve must comply with
the performance standards in § 192.381, including§ 192.381 (b) which states "An operator shall
locate an excess flow valve as near as practical to the fitting connecting the service line to its
source of gas supply."
The Pipeline and Hazardous Materials Safety Administration. Office of Pipeline Safety provides written clarifications of the Regulations (49 CFR
Parts 190-199) in the form of interpretation letters. These letters reflect the agency's current application of the regulations to the specific facts
presented by the person requesting the clarification. Interpretations do not create legally-enforceable rights or obligations and are provided to
help the public understand how to comply with the regulations.

We agree with your understanding that if an excess flow valve is installed, it should be placed as
near to the source of gas supply as practical to ensure the excess flow valve protects the
maximum length of service line. An excess flow valve is required if the service line from the
main to the customer's house, or a segment of service line near the fitting connecting the main to
the service line (where an excess flow valve is usually located), is replaced. However, an excess
flow valve is not required for replacement of short segments of service line far away from the
main or source of supply because excess flow valves in those locations may not provide
excavation-damage protection.
If we can be of further assistance, please contact Tewabe Ase be at 202-366-5523.

Re: Request for Letter of Interpretation
The Rhode Island Division of Public Utilities and Carriers (RIDPUC) requests an
interpretation of The Pipeline Safety Regulations 49 CFR Part 192.381(d) Service Lines:
Excess flow valve performance standards which states,
(d) An operator shall locate an excess flow valve as near as
practical to the fitting connecting the service line to its source
of gas supply.
Our interpretation relates to the particular situation where a gas service line that did not
originally have an excess flow installed on it is required to be repaired due to excavation
activities damaging the line requiring a section to be cut out and replaced with a new piece
of pipe. In the particular case where the gas service line did not originally have an excess
flow valve installed the operator is therefore required to install an excess flow valve if all the
criteria are met as described in 49 CFR Part 192.383(b)(1-4) Excess flow valve installation
which states,
An excess flow valve must be installed on any new or
replaced service line serving a single-family residence after
February 12, 2010, unless one or more of the following
conditions is present: (1) The service line does not operate at
a pressure of 10 psig or greater throughout the year; (2) The

operator has prior experience with contaminants in the gas
stream that could interfere with the EFV's operation or cause
loss of service to a residence; (3) An EFV could interfere with
necessary operation or maintenance activities, such as
blowing liquids from the line; or (4) An EFV meeting
performance standards in §192.381 is not commercially
available to the operator.
Assuming all the criteria above is met the operator would be required to install an excess
flow valve to the repaired service line since the cut out pipe section meets the definition of a
Replaced service line as defined in 49 CFR Part 192.383(a) Excess flow valve installation
which states,
Replaced service line means a gas service line where the
fitting that connects the service line to the main is replaced or
the piping connected to this fitting is replaced.
At this point the operator is required to install the excess flow valve to meet compliance
with Part 192.381(d) Service Lines: Excess flow valve performance standards. The Division
interprets Part 192.381(d) as requiring the installation of the excess flow valve at the main in
close proximity to the fitting connecting the service line to its source of gas supply and not at
the point of the excavation damage. For example if the repair is made only several feet
from the foundation wall of the residence the installation of an excess flow valve in such
close proximity to the foundation wall would provide very little safety for future excavation
activity. The misinterpretation of the word “practical” and the installation the excess flow
valve at the point of the excavation damage as a quick fix undermines the true safety
benefits of the excess flow valve. Excess flow valves can provide protection to the gas
customer properties from the consequences of a break in the service line.
The Division requests a Letter of Interpretation from PHMSA regarding the above issue.
