1 Reasons for Agency Action
Executive Order 12866 states that "Federal agencies should promulgate only such regulations as are
required by law, are necessary to interpret the law, or are made necessary by compelling need, such as
material failures of private markets to protect or improve the health and safety of the public, the
environment, or the well-being of the American people ... ." Part of the mission of the Pipeline and
Hazardous Materials Safety Administration (PHMSA) is to ensure the safety of the natural gas system.
Government regulation of pipeline safety standards addresses the market failure of negative
externalities, namely the costs that pipeline incidents impose on other parties for which there is no
market compensation. Recognizing the safety benefits of excess flow valve installation in natural gas
distribution systems, Section 22 of the Pipeline Safety, Regulatory Certainty, and Job Creation Act of
2011 directed PHMSA to require the installation of excess flow valves (EFVs) on multi-family residential
and small commercial entities. In addition, PHMSA is required to respond to the National Transportation
Safety Board’s (NTSB) recommendation P-01-2, which recommends that PHMSA “require that excess
flow valves be installed in all new and renewed gas service lines, regardless of a customer’s
classification, when the operating conditions are compatible with readily available valves.” The
proposed rule requires operators of gas distribution pipelines to install EFVs on all new or entirely
replaced residential and commercial service lines where the known load does not exceed 1,000
Standard Cubic Feet per Hour (SCFH) and to install manual shutoff valves on all other new or entirely
replaced lines.
2 Objectives of, and legal basis for, the proposed rule
This proposed rule implements statutory mandates of Section 22 of the Pipeline Safety, Regulatory
Certainty, and Job Creation Act of 2011 by requiring the installation of EFVs on new and entirely
replaced service lines serving branched single-family residences, multi-family residences, and small
commercial entities with known loads not exceeding 1,000 SCFH. The proposed rule also addresses
NTSB recommendation P-01-2, which calls for EFVs to be installed in all new and replaced lines
regardless of customer classification where operating conditions are compatible with readily available
valves. Recognizing that broader expansion of EFVs, particularly where known loads exceed 1,000 SCFH,
presents challenges, PHMSA is proposing the use of curb valves (manual service line shut-off valves) for
facilities with known loads that exceed 1,000 SCFH. PHMSA believes the proposed rule will satisfy
Recommendation P-01-2 by ensuring all service lines have adequate protection from either EFVs or curb
valves according to operational conditions.

3 Description and estimate of the number of small entities to which the
proposed rule will apply
This rule applies to all operators of gas distribution systems. This includes gas distribution operators
who file annual reports with PHMSA, plus master meter and small LPG operators who do not file annual
reports. No data on revenues or headcount are available for master meter and small LPG operators, but
most of the 6,184 operators in these categories1 can be presumed to be small entities due to the nature
of their operations.
Among distribution operators, there were 1,289 operators with unique OPIDs who submitted an annual
report to PHMSA in 2011. These include private natural gas distributors, private companies of other
types that operate service lines, and municipalities. Using a dataset provided by Dun and Bradstreet
with information on these operators, , this analysis breaks down the percentage of each type of
operator within the industry and identifies the percentage that are small businesses. There were 363
companies that identified Natural Gas Distribution as a business operation (the dataset listed up to 6
codes per company). Of those that did not indicate Natural Gas Distribution, 601 included a public NAICS
code (a code beginning with 92). Fifteen operators were unclassified and the remaining 310 were other
companies, largely electric utilities and other petroleum related industries. Figure 1 below summarizes
the breakdown.

operators, for a total of 6,184 operators, as of 9/20/2013.

Natural Gas Distributor Public Sector Entity Other Company Unknown
According to the Small Business Administration’s Table of Size Standards Footnote 19, size standards are
not developed for public sector operations. Instead, “concerns performing operational services for the
administration of a government program are classified under the NAICS private sector industry based on
the activities performed.” The NAICS code for Natural Gas Distribution is 221210 and the small business
size threshold is 500 employees. Of the 1,289 companies, 1,221 (95%) had fewer than 500 employees.
By industry sector, 55 of the 363 natural gas distributors are considered large, or 15%. In the public
sector, eight entities listed more than 500 employees, or 1% of the public sector distribution companies.
Among the other companies, 15, or 5%, listed more than 500 employees. Unclassified operators do not
have employment data.
The table below breaks down operators by type and the number of service lines they operate. It tracks
along with employees fairly closely, with distributors tilting to larger networks and public sector entities
on the smaller end.

Overall, because of the high percentage of gas distribution operators classified as small entities, as well
as the master meter and small LPG operators that are presumed to be small entities, the proposed rule
would impact a substantial number of small entities.
4 Description of the projected reporting, recordkeeping and other
compliance requirements of the proposed rule and their impact on
small entities
4.1 Excess Flow Valves
4.1.1 Requirements
PHMSA proposes to add four new categories of service for which an EFV must be installed on all new or
replaced lines. The four new categories that will be added to the existing requirement (49 CFR §
192.383) for single-family residences (SFRs) served by a single service line are:
- Branched service lines to a SFR installed concurrently with the primary SFR service line (a single
EFV may be installed to protect both lines)
- Branched service lines to an SFR installed off a previously installed SFR service line that does not
contain an EFV
- Multi-family installations, including duplexes, triplexes, and fourplexes with known customer
loads at time of service installation, based on installed meter capacity, that do not exceed 1,000
standard cubic feet per hour (SCFH) per service
- A single, small commercial customer, served by a single service line, with known customer load
at time of service installation, based on installed meter capacity, that do not exceed 1,000 SCFH
per service.
The section will continue to include exceptions for cases where installation would not be feasible. These
exceptions, currently listed in 192.383(b)(1)-(4) of the section, are:
- When the service line does not operate at a pressure of 10 psig or greater throughout the year
- When 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 the customer
- When an EFV could interfere with necessary operations or maintenance activities, such as
blowing liquids from the line

- When an EFV meeting performance standards in 192.381 is not commercially available to the
operator.
The exceptions will reduce the potential cost of the regulation. As there is no data available to estimate
the proportion of lines that are excepted, the analysis will assume conservatively that all lines have
operating conditions suitable for an EFV.
The revision also adds a regulation allowing optional installation of EFVs if requested by a customer.
Because this component deals with voluntary action only, it will not be considered in the regulatory
flexibility analysis. However, the analysis does include the associated notification and recordkeeping
costs for informing customers of this option.
4.1.2 Cost to small entities
Each additional valve imposes a small cost on the operator, as the cost of installation is estimated at $30
per EFV. Industry comments have referred to the cost as “relatively minimal.”2 These costs may be
slightly larger for smaller operators due to economies of scale in purchasing valves; however, the cost is
minimal. Additionally, public operators and natural gas distributors are able to pass on increased costs
through rate adjustments, further minimizing impacts to those entities. The one-time costs incurred by
the operators during the installation of new or replaced service lines provide safety benefits for
approximately 50 years following installation.
4.2 Curb Valve
4.2.1 Requirements
The proposed rule adds section 385 to part 192. This section would require operators to install a manual
service line shut-off valve (curb valve) on any new or replaced service line for which an EFV is not
installed in accordance with section 192.383.
4.2.2 Cost to small entities
Similar to costs related to excess flow valves, each additional valve imposes a small cost on the operator
of approximately $55 per installation. These costs may be slightly larger for smaller operators due to
economies of scale in purchasing valves; however, the cost is minimal. Additionally, public operators and
natural gas distributors are able to pass on increased costs through rate adjustments, further minimizing
impacts to those entities. Similar to EFVs, the one-time costs incurred by the operators during the
installation of new or replaced service lines provide safety benefits for approximately 50 years following
installation.
4.3 Recordkeeping Requirements and Cost to Small Entities
The proposed rule in part expands the scope of an existing rule that requires recordkeeping. Specifically,
operators are required to report annually the number of EFVs installed that calendar year and the total
number of EFVs in their system. This portion of the rule will increase the number of lines subject to the
requirement but does not itself add additional recordkeeping burden. The curb valve requirement, while

new, also imposes no additional recordkeeping requirement. The notification and recordkeeping costs
associated with the new notification requirement for optional EFV installation are estimated at $42 per
firm annually, which is a minimal cost even for the smallest operators.
4.4 Professional Skill Required
No additional professional skills are required. The proposed rule in part expands the scope of an existing
rule to new service lines, so skills required by the previous rule already exist within the entity. The curb
valve requirement, while new, imposes no additional skill requirement as curb valve installation is a
common practice within the industry.
5 Federal rules which may duplicate, overlap or conflict with the
proposed rule
To the best of the knowledge of PHMSA, no other Federal rules duplicate, overlap, or conflict with the
proposed rule.
6 Alternatives Considered
PHMSA considered the following alternatives to the proposed rule: no-action, the full implementation of
NTSB’s Recommendation P-01-2 (requiring EFVs on service lines regardless of known load size), and the
hybrid approach selected. The no-action alternative did not address the objectives of Section 22 of the
Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, and the full implementation of
Recommendation P-01-2 would have increased the potential economic impact of the proposed rule.
Because the proposed rule is focused on ensuring safety and does not have a significant economic
impact on small entities, PHMSA did not consider establishing different compliance or reporting
requirements or timetables for small entities.
7 Effect on the Cost of Credit
The proposed rule is not projected to increase the cost of credit for small entities in any way.
8 Summary and Conclusion
The natural gas distribution industry does have a substantial number of small entities as defined by the
SBA small business threshold of having fewer than 500 employees. However, the rule does not have a
significant impact on small entities because the additional costs are minimal.
