PLEASE NOTE<br />
Addenda to this Guide will also be issued in loose-leaf format so that users will be able to keep the<br />
Guide up-to-date by replacing the pages that have been revised with the new pages. It is advisable,<br />
however, that pages which have been revised be retained so that the chronological development of<br />
the Federal Regulations and the Guide is maintained.<br />
CAUTION<br />
As part of subscription service, <strong>GPTC</strong> (using AGA as Secretariat) will try to keep subscribers<br />
informed on the current Federal Regulations as released by the Department of Transportation (DOT)<br />
This is done by periodically issuing addenda to update both the Federal Regulations and the guide<br />
material. However, the <strong>GPTC</strong> assumes no responsibility in the event the material that is<br />
automatically mailed to subscribers never reaches its destination, or is delivered late. Otherwise, the<br />
subscriber is reminded that the changes to the Regulations can be timely noted on the Federal<br />
Register's web site.<br />
<strong>No</strong> part of this document may be reproduced in any form, in an electronic retrieval system or otherwise,<br />
without the prior written permission of the <strong>American</strong> <strong>Gas</strong> <strong>Association</strong>.<br />
Participation by state and federal agency representative(s) or person(s) affiliated with industry is not to be<br />
interpreted as government or industry endorsement of the guide material in this Guide.<br />

<strong>GPTC</strong> GUIDE FOR GAS TRANSMISSION AND §192.1<br />
DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART A<br />
PART 192<br />
MINIMUM FEDERAL SAFETY STANDARDS<br />
Authority: 49 U.S.C. 5103, 60102, 60104, 60108, 60109, 60110, 60113, and 60118; and 49 CFR 1.53.<br />
Source: 35 FR 13257, Aug. 19, 1970, unless otherwise noted.<br />
SUBPART A<br />
GENERAL<br />
§192.1<br />
What is the scope of this part?<br />
▌[Effective Date: 3-05-07]<br />
(a) This part prescribes minimum safety requirements for pipeline facilities and the transportation<br />
of gas, including pipeline facilities and the transportation of gas within the limits of the outer<br />
continental shelf as that term is defined in the Outer Continental Shelf Lands Act (43 U.S.C. 1331).<br />
(b) This part does not apply to—<br />
(1) Offshore gathering of gas in State waters upstream from the outlet flange of each facility<br />
where hydrocarbons are produced or where produced hydrocarbons are first separated, dehydrated, or<br />
otherwise processed, whichever facility is farther downstream;<br />
(2) Pipelines on the Outer Continental Shelf (OCS) that are producer-operated and cross into<br />
State waters without first connecting to a transporting operator’s facility on the OCS, upstream<br />
(generally seaward) of the last valve on the last production facility on the OCS. Safety equipment<br />
protecting PHMSA-regulated pipeline segments is not excluded. Producing operators for those pipeline<br />
segments upstream of the last valve of the last production facility on the OCS may petition the<br />
Administrator, or designee, for approval to operate under PHMSA regulations governing pipeline<br />
design, construction, operation, and maintenance under 49 CFR 190.9;<br />
(3) Pipelines on the Outer Continental Shelf upstream of the point at which operating<br />
responsibility transfers from a producing operator to a transporting operator;<br />
(4) Onshore gathering of gas—<br />
(i) Through a pipeline that operates at less than 0 psig (0 kPa);<br />
(ii) Through a pipeline that is not a regulated onshore gathering line (as determined in<br />
§192.8); and<br />
(iii) Within inlets of the Gulf of Mexico, except for the requirements in §192.612; or<br />
(5) Any pipeline system that transports only petroleum gas or petroleum gas/air mixtures to—<br />
(i) Fewer than 10 customers, if no portion of the system is located in a public place; or<br />
(ii) A single customer, if the system is located entirely on the customer’s premises (no<br />
matter if a portion of the system is located in a public place).<br />

Sample piping is pipe, valves, and fittings used for the collection of samples of gas or other fluids.<br />
SCADA is supervisory control and data acquisition. SCADA is a remote control system that allows the<br />
transmission of data from a remote site (e.g., a delivery point) to a central control location. SCADA<br />
systems are used to monitor and control flow, pressure, and other parameters of the pipeline system.<br />
SCADA systems may generate an alarm when an event has occurred or an unusual situation is<br />
developing.<br />
Seamless pipe is a wrought tubular product made without a welded seam. It is manufactured by hot working<br />
steel or, if necessary, by subsequently cold finishing the hot-worked tubular product to produce the<br />
desired shape, dimensions, and properties. See also Pipe manufacturing processes.<br />
Secondary stress is stress created in the pipe wall by loads other than internal fluid pressure. Examples are<br />
backfill loads, traffic loads, beam action in a span and loads at supports and at connections to the pipe.<br />
Service line valve is a valve located in the service line ahead of the service regulator, or ahead of the meter<br />
where there is no regulator.<br />
Solvent cement joint is a joint made in PVC piping by using solvent cement to join the piping components.<br />
Standup pressure test is a test to demonstrate that a pipe or piping system does not leak as evidenced by<br />
the lack of a drop in pressure over a specified period of time after the source of pressure has been<br />
isolated.<br />
Steel is an iron-base alloy, malleable in some temperature range as initially cast, containing manganese,<br />
carbon, and often other alloying elements. See also Carbon steel.<br />
Stress is the resultant internal force that resists change in the size or shape of a body acted on by external<br />
forces. See also Hoop stress, Maximum allowable hoop stress, Operating stress, Secondary stress,<br />

sustain before failure (psi)<br />
Thermoplastic is a plastic, which is capable of being repeatedly softened by increase of temperature and<br />
hardened by decrease of temperature.<br />
Thermosetting plastic is a plastic that is capable of being changed into a substantially infusible or insoluble<br />
product when cured under the application of heat or by chemical means.<br />
Thickness. See <strong>No</strong>minal wall thickness.<br />
Valve. See Curb valve and Service line valve.<br />
Vault is an underground structure which may be entered, and which is designed to contain piping and piping<br />
components, such as valves or pressure regulators.<br />
Yield strength is the strength at which a material exhibits a specified limiting permanent set, or produces a<br />
specified total elongation under load. The specified limiting set or elongation is usually expressed as a<br />
percentage of gage length, and its values are specified in the various material specifications acceptable<br />
under this Guide.<br />

§192.8<br />
How are onshore gathering lines and regulated onshore gathering<br />
lines determined?<br />
[Effective Date: 4-14-06]<br />
(a) An operator must use API RP 80 (incorporated by reference, see §192.7), to determine if<br />
an onshore pipeline (or part of a connected series of pipelines) is an onshore gathering line. The<br />
determination is subject to the limitations listed below. After making this determination, an<br />
operator must determine if the onshore gathering line is a regulated onshore gathering line under<br />
paragraph (b) of this section.<br />
(1) The beginning of gathering, under section 2.2(a)(1) of API RP 80, may not extend<br />
beyond the furthermost downstream point in a production operation as defined in section 2.3 of<br />
API RP 80. This furthermost downstream point does not include equipment that can be used in<br />
either production or transportation, such as separators or dehydrators, unless that equipment is<br />
involved in the processes of ‘‘production and preparation for transportation or delivery of<br />
hydrocarbon gas’’ within the meaning of ‘‘production operation.’’<br />
(2) The endpoint of gathering, under section 2.2(a)(1)(A) of API RP 80, may not extend<br />
beyond the first downstream natural gas processing plant, unless the operator can demonstrate,<br />
using sound engineering principles, that gathering extends to a further downstream plant.<br />
(3) If the endpoint of gathering, under section 2.2(a)(1)(C) of API RP 80, is determined by<br />
the commingling of gas from separate production fields, the fields may not be more than 50 miles<br />
from each other, unless the Administrator finds a longer separation distance is justified in a<br />
particular case (see 49 CFR §190.9).<br />
(4) The endpoint of gathering, under section 2.2(a)(1)(D) of API RP 80, may not extend<br />
beyond the furthermost downstream compressor used to increase gathering line pressure for<br />
delivery to another pipeline.<br />
(b) For purposes of §192.9, ‘‘regulated onshore gathering line’’ means:<br />
(1) Each onshore gathering line (or segment of onshore gathering line) with a feature<br />
described in the second column that lies in an area described in the third column; and<br />
(2) As applicable, additional lengths of line described in the fourth column to provide a<br />
safety buffer:<br />

3 MINIMUM REQUIRED WALL THICKNESS<br />
The minimum wall thickness (tm) for a given design pressure is determined from the formula below.<br />
Also, see §§192.123 (c) and (d) plus 3 of the guide material under §192.123.<br />
Where:<br />
tm = PD<br />
(P + 0.64 S)<br />
P = Design pressure, gauge, kPa (psi)<br />
D = Specified outside diameter, mm (in.)<br />
S = The long-term hydrostatic strength, for thermoplastic pipe, kPa (psi) determined at 23 o C<br />
(73 o F), 38 o C (100 o F), 49 o C (120 o F), or 60 o C (140 o F); for reinforced thermosetting<br />
pipe, 75,800 kPa (11,000 psi)<br />
4 INTERPOLATION OF HYDROSTATIC DESIGN BASIS (HDB) VALUES<br />
(a) For thermoplastic pipe that is to be installed at a service temperature greater than 73 ºF and less<br />
than that at which the next HDB has been established, the HDB at the anticipated service<br />
temperature can be determined by interpolation. The pipe manufacturer should be consulted for<br />
assistance in determining an interpolated HDB.<br />
(b) The interpolation formula as prescribed in §192.121 is published in PPI TR-3 as follows.<br />

)<br />
TH<br />
ST = Interpolated LTHS for the anticipated service temperature (psi)<br />
SL = LTHS established at a temperature below the anticipated service temperature (psi)<br />
SH = LTHS established at a temperature above the anticipated service temperature (psi)<br />
TL = Temperature at which the lower LTHS (SL) was established (K)<br />
TT = Anticipated service temperature (K)<br />
TH = Temperature at which the higher LTHS (SH) was established (K)<br />
(c) Section 192.121 requires that the interpolation be made between the LTHS values at the lower and<br />
higher temperatures. The resulting interpolated LTHS is categorized into an HDB. This interpolated<br />
HDB is then used to determine the design pressure under §192.121.<br />
(d) Example:<br />
An operator is installing SDR 11 PE pipe where the anticipated service temperature is 78 ºF. HDB<br />
values are established and published in PPI TR-4 at 73 ºF (296 K) and 140 ºF (333 K). Thus, the<br />
operator has the option of establishing an interpolated HDB at the anticipated service temperature,<br />
78 °F (299 K), or using the 140 °F HDB of 800 psi.<br />
(1) In order to calculate the HDB for the anticipated service temperature, the operator must obtain<br />
the actual LTHS values established for the material at the nearest temperature above and<br />
below the temperature for which the interpolated value is to be determined. These values are<br />
typically available from the pipe supplier. If these LTHS values are not available, the lowest<br />
LTHS for the HDB category in Table 192.121ii may be used as a conservative estimate.<br />
(2) Once the LTHS values are obtained, the interpolation calculation input is as follows.<br />
SL(73 °F) = 1567 psi<br />
SH(140 °F) = 845 psi<br />
TL = 73 ºF (295.93 K)<br />
TT = 78 ºF (298.71 K)<br />
TH = 140 ºF (333.15 K)<br />

2 INSTALLATION CONSIDERATIONS<br />
GUIDE MATERIAL<br />
(a) Attention should be given to a new pipeline's physical location, particularly if the location may<br />
subject the pipeline to stray electrical currents from other facilities, such as the following.<br />
(1) Other pipelines or utilities with associated cathodic protection systems.<br />
(2) Rail transit systems.<br />
(3) Mining or welding operations.<br />
(4) Induced currents from electrical transmission lines.<br />
(b) To the extent possible, the operator should identify and plan for the mitigation and control of<br />
anticipated stray electrical currents prior to construction. As soon as practicable after construction<br />
of the pipeline or facility to be protected is completed, the operator should implement monitoring,<br />
testing, and mitigation plans to control the effects of stray electrical currents. The rate of corrosion<br />
caused by stray electrical current can be higher than the rate of corrosion resulting from galvanic<br />
action.<br />
3 EXTERNAL CORROSION CONTROL EFFECTIVENESS<br />

DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART I<br />
1 GENERAL<br />
GUIDE MATERIAL<br />
In the presence of free water, gases containing certain constituents, such as carbon dioxide, hydrogen<br />
sulfide, and oxygen, can be corrosive to steel pipelines. Pipeline liquids may combine with these<br />
constituents and cause corrosion that may be detrimental to pipeline integrity. Because of this,<br />
monitoring and evaluating corrosion, operating conditions, gas quality, and liquids found in pipelines are<br />
important elements of internal corrosion control programs. The following are considerations for<br />
managing internal corrosion.<br />
2 DESIGN CONSIDERATIONS<br />
If it is anticipated or has been determined that the gas to be transported is corrosive, the following<br />
should be considered for the design of the pipeline system.<br />
(a) Selection of special materials.<br />
(1) <strong>No</strong>nmetallic materials.<br />
(2) <strong>No</strong>nferrous metals.<br />
(3) Special alloy steels.<br />
(b) Selection of steel pipe.<br />
(1) Increased wall thickness.<br />
(2) Pipe grade.<br />
(3) Metallurgy.<br />
(4) Internal coating.<br />
(c) Effect of high, low, or no flow velocities and liquid accumulation.<br />
(d) Piping configurations that can contribute to changes in flow velocities, which can cause the<br />
free water and constituents to settle out of the gas stream and build into concentrations that<br />
could lead to internal corrosion. Examples of these configurations include the following.<br />
(1) Dead ends.<br />
(2) Sags or low spots.<br />
(3) Fittings and mechanical connections.<br />
(4) Sharp bends (vertical or horizontal).<br />
(5) Sudden diameter changes.<br />
(6) Drips.<br />
(e) Corrosion monitoring devices and access fittings for them.<br />
(f) Physical location of the pipe, since external climate, heat sources, and environment can affect<br />
internal temperature.<br />
(g) Selection and location of liquid separation, dehydration, or gas scrubbing equipment.<br />
3 DETECTION METHODS<br />
The following may be used to detect internal corrosion.<br />
(a) Visual inspection of piping and components.<br />
(1) Access ports.<br />
(2) Selective cut-outs.<br />
(b) Corrosion monitoring devices.<br />
(1) Corrosion coupons and spools.<br />
(2) Resistance probes.<br />
(3) Polarization probes.<br />
(4) Hydrogen probes and patches.<br />
(5) Electrochemical probes.<br />
(c) Sampling.<br />
(1) Liquids analysis.<br />
(i) Chemical composition.<br />

(e) Internal inspection tools.<br />
(f) Ultrasonic inspection.<br />
(g) Radiography.<br />
(h) Failure analysis.<br />
(i) Internal corrosion direct assessment.<br />
4 FREQUENCY<br />
The following considerations could impact the frequency of monitoring or testing.<br />
(a) Location and history of water removal.<br />
(b) Age and condition of pipe and drips.<br />
(c) Internal corrosion history, including leaks and ruptures.<br />
(d) Liquids composition.<br />
(e) <strong>Gas</strong> composition.<br />
(f) System operating parameters (e.g., temperature, pressure, volumes transported, wet system vs.<br />
dry).<br />
(g) System physical layout (e.g., topography).<br />
(h) Flow characteristics.<br />
(i) Proximity to dwellings and the public.<br />
(j) Pipeline segments downstream of production or storage fields where free water and constituents<br />
might accumulate.<br />
(k) Solids composition.<br />
(l) Past inspection results.<br />
(m) Past results obtained using corrosion monitoring devices.<br />
(n) System design (e.g., materials of construction, pipe wall thickness, pigging facilities, presence of<br />
drips).<br />
5 MITIGATIVE MEASURES<br />
The following measures can be used to mitigate internal corrosion.<br />
(a) Control of moisture level (e.g., by dehydration, separation, or temperature control).<br />
(b) Reduction of corrosive constituents (chemical or biological) in the gas.<br />
(c) Internal coating.<br />
(d) Liquids or solids removal.<br />
(1) Pigging - frequency of pigging will depend on both the volume and the analysis of materials<br />
received during pigging operations.<br />
(2) Drips - frequency of operation will depend on both the volume and analysis of materials<br />
removed.<br />
(3) Separators - frequency of maintenance will depend on changes in results from liquids analyses.<br />
(e) Chemical or biological treatments.<br />
(1) Treatments should not cause deterioration of piping system components.<br />
(2) Treatments should be compatible with the following.<br />
(i) <strong>Gas</strong> being transported.<br />
(ii) Downstream gas utilization and processing equipment.<br />
(iii) Any other treatments.<br />

� Internal corrosion control: Design and construction of transmission line.<br />
� [Effective Date:5-23-07]<br />
(a) Design and construction. Except as provided in paragraph (b) of this section, each new<br />
transmission line and each replacement of line pipe, valve, fitting, or other line component in a<br />
transmission line must have features incorporated into its design and construction to reduce the<br />
risk of internal corrosion. At a minimum, unless it is impracticable or unnecessary to do so, each<br />
new transmission line or replacement of line pipe, valve, fitting, or other line component in a<br />
transmission line must:<br />
(1) Be configured to reduce the risk that liquids will collect in the line;<br />
(2) Have effective liquid removal features whenever the configuration would allow liquids<br />
to collect; and<br />
(3) Allow use of devices for monitoring internal corrosion at locations with significant<br />
potential for internal corrosion.<br />
(b) Exceptions to applicability. The design and construction requirements of paragraph (a) of<br />
this section do not apply to the following:<br />
(1) Offshore pipeline; and<br />
(2) Pipeline installed or line pipe, valve, fitting or other line component replaced before<br />
May 23, <strong>2007</strong>.<br />
(c) Change to existing transmission line. When an operator changes the configuration of a<br />
transmission line, the operator must evaluate the impact of the change on internal corrosion risk<br />
to the downstream portion of an existing onshore transmission line and provide for removal of<br />
liquids and monitoring of internal corrosion as appropriate.

access to the structure being inspected. In addition to the locations listed in §192.481(b),<br />
attention should be given to locations such as clamps, rest plates, and sleeved openings.<br />
(2) Piping that is thermally or acoustically insulated (jacketed) should be inspected wherever<br />
practical. To minimize damage to the insulation, a visual inspection of the pipe may be<br />
performed by cutting windows into the insulation.<br />

or to determine a lower MAOP. The pressure test should be in accordance with the general<br />
requirements of Subpart J (in particular §192.503), and the pressure should be held for at least 8<br />
hours. The established MAOP may be confirmed by testing to a pressure at least equal to the MAOP<br />
times the appropriate factor in Table 192.485i or ii below. A lower MAOP may be established by<br />
dividing the successful test pressure by the appropriate factor.<br />

2 REPAIR OR REPLACEMENT<br />
If a pipeline has an area of external corrosion that disqualifies it for service at the established MAOP, or<br />
if the MAOP cannot be reduced to the indicated safe level, it should be repaired or replaced. For<br />
acceptable methods of repair, see §§192.711(b), 192.717, and guide material under §192.713.<br />

DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART J<br />
1 GENERAL<br />
GUIDE MATERIAL<br />
The following preliminary considerations should be noted.<br />
(a) Because of the requirements of §192.611 and the possibility of a change in class location,<br />
especially in Class 1 and Class 2 locations, a strength test to at least 90 percent SMYS is<br />
recommended.<br />
(b) Pipelines and mains crossing highways and railroads may be tested in the same manner and to the<br />
same pressure as the pipeline on each side of the crossing.<br />
(c) Fabricated assemblies (e.g., mainline valve assemblies, crossover connections, and river crossing<br />
headers) installed in pipelines in Class 1 locations may be tested as required for Class 1 locations<br />
(even though §192.111 requires a Class 2 design factor).<br />
(d) Testing against closed valves is not recommended. Testing should include the use of test<br />
manifolds. Blinds (e.g., flanges or plates) should be used as necessary to minimize testing against<br />
any closed valves. Where valves exist in a test section, they should remain in the open or<br />
manufacturer’s recommended position during the test. To ensure that air does not enter the gas<br />
system, testing with air against a closed valve that is connected to the gas system is not advisable.<br />
(e) A single component with a valid ASME or MSS specification pressure rating may be installed<br />
without a pressure test. Rating examples are common designations, such as ASME Class 600.<br />
Corresponding temperature limits need to be considered for each pressure rating.<br />
2 TEST PROCEDURE<br />
The test procedure used should be selected after giving due consideration to items such as the<br />
following.<br />
(a) Equipment to be used.<br />
(b) Test medium.*<br />
(c) Environment.<br />
(d) Elevation profile.<br />
(e) Volumetric content of the line.<br />
(f) Test pressure.*<br />
(g) Duration of the test.*<br />
(h) Location of the line.<br />
(i) The effects of temperature changes on the pressure of the test medium.<br />
*See Guide Material Appendix G-192-9.<br />
3 HYDROSTATIC TEST<br />
3.1 Test preparation.<br />
It is recommended that the pipeline segment to be tested be physically isolated from all other pipelines.<br />
See 1(d) above. Testing against closed valves is not recommended. Weld caps, blind flanges, or other<br />
devices of appropriate design should be utilized to seal pipe ends. It is also recommended that spheres<br />
or squeegees be inserted in the pipeline ahead of the water to reduce air entrapment while filling and to<br />
facilitate dewatering operations.<br />
3.2 Test evaluation.<br />
(a) General.<br />
In order that intelligent interpretation of pressure variations can be made, it is important that<br />
accurate thermometers, deadweight pressure gauges, meters, etc., be used and that the readings<br />
be taken at properly located points and at proper intervals of time. The use of a pressure-volume<br />
plot is recommended for tests that are planned to approach SMYS.<br />
(b) Small changes in pressure during hold period.<br />
Experience has shown that a small steady decline in pressure often occurs during the hold period.<br />
This does not necessarily indicate the existence of a leak. Such declines can often be caused by a<br />
change in temperature of the test liquid, a small entrapment of air, or a leaking gauge connection. A<br />
Amendment <strong>No</strong>. 8, April <strong>2007</strong> 169
<strong>GPTC</strong> GUIDE FOR GAS TRANSMISSION AND §192.505<br />
DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART J<br />
pressure rise is usually caused by the warming of air trapped in the structure or the warming of the<br />
test liquid or both. When an appreciable amount of pipe is exposed to atmosphere (not backfilled)<br />
during the test, temperature effects are sometimes quite pronounced.<br />
In the event of a small steady pressure decline, it is considered good practice to periodically add<br />
liquid, thereby maintaining the desired pressure until the hold period is completed. Likewise, it is<br />
also considered good practice to bleed off small quantities of test liquid to prevent exceeding the<br />
maximum selected pressure.<br />
3.3 Locating minor leaks.<br />
When a hydrostatic strength proof test has been completed and there are indications of a minor leak<br />
which was not located during the test, the line may be filled with natural or other detectable gas at a<br />
pressure less than or equal to the maximum allowable operating pressure of the section of line being<br />
tested; and a suitable gas detection device (e.g., flame ionization analyzer, controlled catalytic<br />
combustion unit, infrared analyzer, or nitrous oxide detector) used to search for the leak.<br />
3.4 Repairs.<br />
Temporary repairs may be made in order not to interrupt the test, and a permanent repair made after<br />
completing the test and before placing the line in service. If permanent repairs are made after the<br />
conclusion of the test using pretested pipe, the tie-in welds must be inspected in accordance with<br />
§192.241.<br />
4 AIR, INERT, OR NATURAL GAS TEST<br />
Maximum hoop stress limitations are specified by §192.503(c). More stringent requirements for<br />
conducting such strength tests within 300 feet of buildings designed for human occupancy are specified<br />
by §192.505(a).<br />
4.1 Test preparation.<br />
(a) It is recommended that the pipeline segment to be tested be physically isolated from all other<br />
pipelines. See 1(d) above. Testing against closed valves is not recommended. Weld caps, blind<br />
flanges, or other devices of appropriate design should be utilized to seal pipe ends.<br />
(b) Purging should be considered to prevent an explosive air-gas mixture in the test segment. Refer to<br />
§§192.629 and 192.751 and the accompanying guide material.<br />
(c) In order that intelligent interpretation of pressure variations can be made, it is important that<br />
accurate thermometers, deadweight pressure gauges, meters, etc. be used and that the readings<br />
be taken at properly located points and at proper intervals of time.<br />
4.2 Test procedure.<br />
It is recommended that pressure in the test segment be applied in increments equal to 25 percent of the<br />
total test pressure. At the end of each incremental increase, the pressure should be maintained while<br />
the test segment is checked for leaks or other sources of rapid decline in pressure.<br />
4.3 Locating leaks.<br />
The location of leaks may be determined visually, by sound, by smell, or by utilizing leak detection<br />
equipment. The leak detection method to be used is dependent upon the test media. Caution -- multiple<br />
leaks may exist.<br />
4.4 Repairs.<br />
It may be prudent to lower pressure in the test segment prior to exposing the pipe for repair. While<br />
temporary repairs may be made to accommodate the test, permanent repairs must satisfy requirements<br />
of §§192.309, 192.711, 192.713, 192.715, or 192.717 as applicable.<br />

1.3 Increased frequency.<br />
Consideration should be given to increased frequency for leakage surveys based on the particular<br />
circumstances and conditions. Surveys should be conducted most frequently in those areas with the<br />
greatest potential for leakage and where leakage could be expected to create a hazard. Factors to be<br />
considered in establishing the frequency of leakage surveys include the following.<br />
(a) Piping system. Age of pipe, materials, type of facilities, operating pressure, leak history records,<br />
and other studies.<br />
(b) Corrosion. Known areas of significant corrosion, or areas where corrosive environments are known<br />
to exist. Cased crossings of roads, highways, railroads, etc., due to susceptibility to unique<br />
corrosive conditions.<br />
(c) Piping location. Proximity to buildings or other structures and the type and use of the buildings.<br />
Proximity to areas of concentrations of people.<br />
(d) Environmental conditions and construction activity. Conditions that could increase the potential<br />
for leakage or cause leaking gas to migrate to an area where it could create a hazard, such as<br />
the following.<br />
(1) Weather conditions.<br />
(2) Areas of known frost heaving.<br />
(3) Wall to wall pavement.<br />
(4) Porous soil conditions.<br />
(5) Areas of high construction activity.<br />
(6) Trenchless excavation activities (e.g., boring).<br />
(7) Blasting. See Guide Material Appendix G-192-16.<br />
(8) Large earth moving equipment.<br />
(9) Heavy traffic.<br />
(10) Unstable soil or areas subject to earth movement.<br />
(e) Other. Any other condition known to the operator that has significant potential to initiate a leak or<br />
to permit leaking gas to migrate to an area where it could result in a hazard, such as the<br />
following.<br />
(1) Earthquake.<br />
(2) Subsidence.<br />
(3) Flooding.<br />
(4) An increase in operating pressure.<br />
(5) The extensive growth of tree roots around pipeline facilities that can exert substantial<br />
longitudinal force on the pipe and nearby joints.<br />
1.4 Special one-time surveys.<br />
Special one-time surveys should be considered following exposure of the pipeline to unusual stresses<br />
(e.g., earthquakes, blasting) or trenchless installation of foreign buried facilities that cross gas pipelines.<br />
1.5 Establishment and review of survey frequency.<br />
Leakage survey frequencies should be based on operating experience, sound judgment, and a<br />
knowledge of the system. Once established, frequencies should be reviewed periodically to affirm that<br />
they are still appropriate. Leakage surveys may be accomplished in conjunction with patrolling,<br />
scheduled inspections, and other routine activities.<br />

The following general procedures are recommended and should be applied where appropriate. For planned<br />
shutdown in connection with abandonment or deactivation, see Guide Material Appendix G-192-12.<br />
1 ABANDONMENT OF TRANSMISSION PIPELINES AND DISTRIBUTION MAINS<br />
1.1 Check prior to abandonment.<br />
Office records should be checked and necessary field checks should be made to ensure the pipelines<br />
or mains scheduled for abandonment are disconnected from all sources and supplies of gas, such as<br />
other pipelines, mains, cross-over piping, meter stations, customer piping, control lines, and other<br />
appurtenances.<br />
1.2 Residual gas or hydrocarbons.<br />
Abandonment should not be completed until it has been determined that the volume of natural gas or<br />
liquid hydrocarbons contained within the abandoned section poses no potential hazard. Generally, it is<br />
advisable to purge 8-inch and larger pipe and long segments of smaller diameter pipe.<br />
1.3 Purging.<br />
Pipelines or mains may be purged using air, inert gas, or water. If air is used as the purging agent,<br />
precautions should be taken to ensure that no liquid hydrocarbons are present. See §192.629 and AGA<br />
XK0101, “Purging Principles and Practice” for purging of natural gas and liquid hydrocarbons.<br />

The following definitions apply to this subpart.<br />
Assessment is the use of testing techniques as allowed in this subpart to ascertain the<br />
condition of a covered pipeline segment.<br />
Confirmatory direct assessment is an integrity assessment method using more focused<br />
application of the principles and techniques of direct assessment to identify internal and external<br />
corrosion in a covered transmission pipeline segment.<br />
Covered segment or covered pipeline segment means a segment of gas transmission pipeline<br />
located in a high consequence area. The terms gas and transmission line are defined in §192.3.<br />

<strong>GPTC</strong> GUIDE FOR GAS TRANSMISSION AND §192.903<br />
DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART O<br />
Direct assessment is an integrity assessment method that utilizes a process to evaluate certain<br />
threats (i.e., external corrosion, internal corrosion and stress corrosion cracking) to a covered<br />
pipeline segment’s integrity. The process includes the gathering and integration of risk factor data,<br />
indirect examination or analysis to identify areas of suspected corrosion, direct examination of the<br />
pipeline in these areas, and post assessment evaluation.<br />
High consequence area means an area established by one of the methods described in<br />
paragraphs (1) or (2) as follows:<br />
(1) An area defined as —<br />
(i) A Class 3 location under §192.5; or<br />
(ii) A Class 4 location under §192.5; or<br />
(iii) Any area in a Class 1 or Class 2 location where the potential impact radius is<br />
greater than 660 feet (200 meters), and the area within a potential impact circle contains 20 or more<br />
buildings intended for human occupancy; or<br />
(iv) Any area in a Class 1 or Class 2 location where the potential impact circle contains<br />
an identified site.<br />
(2) The area within a potential impact circle containing —<br />
(i) 20 or more buildings intended for human occupancy, unless the exception in<br />
paragraph (4) applies; or<br />
(ii) An identified site.<br />
(3) Where a potential impact circle is calculated under either method (1) or (2) to establish a<br />
high consequence area, the length of the high consequence area extends axially along the length of<br />
the pipeline from the outermost edge of the first potential impact circle that contains either an<br />
identified site or 20 or more buildings intended for human occupancy to the outermost edge of the<br />
last contiguous potential impact circle that contains either an identified site or 20 or more buildings<br />
intended for human occupancy. (See Figure E.I.A. in Appendix E.)<br />
(4) If in identifying a high consequence area under paragraph (1)(iii) of this definition or<br />
paragraph (2)(i) of this definition, the radius of the potential impact circle is greater than 660 feet (200<br />
meters), the operator may identify a high consequence area based on a prorated number of<br />
buildings intended for human occupancy with a distance 660 feet (200 meters) from the centerline of<br />
the pipeline until December 17, 2006. If an operator chooses this approach, the operator must<br />
prorate the number of buildings intended for human occupancy based on the ratio of an area with a<br />
radius of 660 feet (200 meters) to the area of the potential impact circle (i.e., the prorated number of<br />
buildings intended for human occupancy is equal to [20 x (660 feet [or 200 meters]/ potential impact<br />
radius in feet [or meters]) 2 ]).<br />
Identified site means each of the following areas:<br />
(a) An outside area or open structure that is occupied by twenty (20) or more persons on at<br />
least 50 days in any twelve (12)-month period. (The days need not be consecutive). Examples<br />
include but are not limited to, beaches, playgrounds, recreational facilities, camping grounds,<br />
outdoor theaters, stadiums, recreational areas near a body of water, or areas outside a rural building<br />
such as a religious facility); or<br />
(b) A building that is occupied by twenty (20) or more persons on at least five (5) days a<br />
week for ten (10) weeks in any twelve (12)-month period. (The days and weeks need not be<br />
consecutive). Examples include, but are not limited to, religious facilities, office buildings,<br />
community centers, general stores, 4-H facilities, or roller skating rinks); or<br />
(c) A facility occupied by persons who are confined, are of impaired mobility, or would be<br />
difficult to evacuate. Examples include but are not limited to hospitals, prisons, schools, day-care<br />
facilities, retirement facilities or assisted-living facilities.<br />
Potential impact circle is a circle of radius equal to the potential impact radius (PIR).<br />
Potential impact radius (PIR) means the radius of a circle within which the potential failure of a<br />
pipeline could have significant impact on people or property. PIR is determined by the formula r =<br />
0.69 * (square root of (p*d 2 )), where ‘r’ is the radius of a circular area in feet surrounding the point of<br />
failure, ‘p’ is the maximum allowable operating pressure (MAOP) in the pipeline segment in pounds<br />
per square inch and ‘d’ is the nominal diameter of the pipeline in inches.<br />

accordance with §192.931. The table that follows this section sets forth the maximum allowed<br />
reassessment intervals.<br />
(1) Pressure test or internal inspection or other equivalent technology. An operator that<br />
uses pressure testing or internal inspection as an assessment method must establish the<br />
reassessment interval for a covered pipeline segment by —<br />
(i) Basing the interval on the identified threats for the covered segment (see §192.917)<br />
and on the analysis of the results from the last integrity assessment and from the data integration<br />
and risk assessment required by §192.917; or<br />
(ii) Using the intervals specified for different stress levels of pipeline (operating at or<br />
above 30% SMYS) listed in ASME/ANSI B31.8S, section 5, Table 3.<br />
(2) External Corrosion Direct Assessment. An operator that uses ECDA that meets the<br />
requirements of this subpart must determine the reassessment interval according to the<br />
requirements in paragraphs 6.2 and 6.3 of NACE RP0502-2002 (incorporated by reference, see<br />
§192.7).<br />
(3) Internal Corrosion or SCC Direct Assessment. An operator that uses ICDA or SCCDA in<br />
accordance with the requirements of this subpart must determine the reassessment interval<br />
according to the following method. However, the reassessment interval cannot exceed those<br />
specified for direct assessment in ASME/ANSI B31.8S, section 5, Table 3.<br />
(i) Determine the largest defect most likely to remain in the covered segment and the<br />
corrosion rate appropriate for the pipe, soil and protection conditions;<br />
(ii) Use the largest remaining defect as the size of the largest defect discovered in the<br />
SCC or ICDA segment; and<br />
(iii) Estimate the reassessment interval as half the time required for the largest defect<br />
to grow to a critical size.<br />
(b) Pipelines Operating Below 30% SMYS. An operator must establish a reassessment interval<br />
for each covered segment operating below 30% SMYS in accordance with the requirements of this<br />
section. The maximum reassessment interval by an allowable reassessment method is seven years.<br />
An operator must establish reassessment by at least one of the following —<br />
(1) Reassessment by pressure test, internal inspection or other equivalent technology<br />
following the requirements in paragraph (a)(1) of this section except that the stress level referenced<br />
in paragraph (a)(1)(ii) of this section would be adjusted to reflect the lower operating stress level. If<br />
an established interval is more than seven years, the operator must conduct by the seventh year of<br />
the interval either a confirmatory direct assessment in accordance with §192.931, or a low stress<br />
reassessment in accordance with §192.941.<br />
(2) Reassessment by ECDA following the requirements in paragraph (a)(2) of this section.<br />
(3) Reassessment by ICDA or SCCDA following the requirements in paragraph (a)(3) of this<br />

§192.941<br />
What is a low stress reassessment?<br />
[Effective Date: 4-6-04]<br />
(a) General. An operator of a transmission line that operates below 30% SMYS may use the<br />
following method to reassess a covered segment in accordance with §192.939. This method of<br />
reassessment addresses the threats of external and internal corrosion. The operator must have<br />
conducted a baseline assessment of the covered segment in accordance with the requirements of<br />
§§192.919 and 192.921.<br />
(b) External corrosion. An operator must take one of the following actions to address external<br />
corrosion on the low stress covered segment.<br />
(1) Cathodically protected pipe. To address the threat of external corrosion on cathodically<br />
protected pipe in a covered segment, an operator must perform an electrical survey (i.e. indirect<br />
examination tool/method) at least every 7 years on the covered segment. An operator must use the<br />
results of each survey as part of an overall evaluation of the cathodic protection and corrosion<br />
threat for the covered segment. This evaluation must consider, at minimum, the leak repair and<br />
inspection records, corrosion monitoring records, exposed pipe inspection records, and the pipeline<br />
environment.<br />
(2) Unprotected pipe or cathodically protected pipe where electrical surveys are impractical.<br />

DISTRIBUTION PIPING SYSTEMS: 2003 Edition SUBPART O<br />
If an electrical survey is impractical on the covered segment an operator must —<br />
(i) Conduct leakage surveys as required by §192.706 at 4-month intervals; and<br />
(ii) Every 18 months, identify and remediate areas of active corrosion by evaluating<br />
leak repair and inspection records, corrosion monitoring records, exposed pipe inspection records,<br />
and the pipeline environment.<br />
(c) Internal Corrosion. To address the threat of internal corrosion on a covered segment, an<br />
operator must —<br />
(1) Conduct a gas analysis for corrosive agents at least once each calendar year;<br />
(2) Conduct periodic testing of fluids removed from the segment. At least once each<br />
calendar year test the fluids removed from each storage field that may affect a covered segment;<br />
and<br />
(3) At least every seven (7) years, integrate data from the analysis and testing required by<br />
paragraphs (c)(1)- (c)(2) with applicable internal corrosion leak records, incident reports, safety-<br />
related condition reports, repair records, patrol records, exposed pipe reports, and test records, and<br />
define and implement appropriate remediation actions.<br />

§192.943<br />
When can an operator deviate from these reassessment intervals?<br />
[Effective Date: 4-6-04]<br />
(a) Waiver from reassessment interval in limited situations. In the following limited instances,<br />
OPS may allow a waiver from a reassessment interval required by §192.939 if OPS finds a waiver<br />
would not be inconsistent with pipeline safety.<br />
(1) Lack of internal inspection tools. An operator who uses internal inspection as an<br />
assessment method may be able to justify a longer reassessment period for a covered segment if<br />
internal inspection tools are not available to assess the line pipe. To justify this, the operator must<br />
demonstrate that it cannot obtain the internal inspection tools within the required reassessment<br />
period and that the actions the operator is taking in the interim ensure the integrity of the covered<br />
segment.<br />
(2) Maintain product supply. An operator may be able to justify a longer reassessment<br />
period for a covered segment if the operator demonstrates that it cannot maintain local product<br />
supply if it conducts the reassessment within the required interval.<br />
(b) How to apply. If one of the conditions specified in paragraph (a)(1) or (a)(2) of this section<br />
applies, an operator may seek a waiver of the required reassessment interval. An operator must<br />
apply for a waiver in accordance with 49 U.S.C. 60118(c), at least 180 days before the end of the<br />
required reassessment interval, unless local product supply issues make the period impractical. If<br />
local product supply issues make the period impractical, an operator must apply for the waiver as<br />
soon as the need for the waiver becomes known.<br />

1 MATERIAL SPECIFICATIONS, CODES, STANDARDS, AND OTHER DOCUMENTS<br />
The publications listed below provide information on pipe, components, specifications, and topics other<br />
than those covered currently or previously by Part 192. The list is intended to include all such<br />
publications referenced throughout the guide material. For some publication titles, certain initial words<br />
have been omitted for brevity, e.g., ASTM B43, "Standard Specification for Seamless Red Brass Pipe,<br />
Standard Sizes" is presented here as "Seamless Red Brass Pipe, Standard Sizes." Under some<br />
conditions, the application of the information is limited by provisions of Part 192 and this Guide. See<br />
Editorial Conventions of the Guide for explanation of "Discontinued." Most material specifications,<br />
codes, standards, and many other documents have been developed and approved in accordance with<br />
<strong>American</strong> National Standards Institute (ANSI) procedures and typically carry added identification<br />
referencing ANSI. Such identification is not routinely shown in the Guide. The appropriate guide<br />
material section is listed for each publication where applicable. Unless otherwise noted, the publications<br />
listed below are the latest available editions.<br />
