§ 195.4 Compatibility necessary for transportation of hazardous liquids or carbon dioxide.

No person may transport any hazardous liquid or carbon dioxide unless the hazardous liquid or carbon dioxide is chemically compatible with both the pipeline, including all components, and any other commodity that it may come into contact with while in the pipeline.

[Amdt. 195–45, 56 FR 26925, June 12, 1991]

§ 195.5 Conversion to service subject to this part.

(a) A steel pipeline previously used inservice not subject to this part qualifies for use under this part if the operator prepares and follows a written procedure to accomplish the following:

(1) The design, construction, operation, and maintenance history of the pipeline must be reviewed and, where sufficient historical records are not available, appropriate tests must be performed to determine if the pipelineis in satisfactory condition for safe operation. If one or more of the variables necessary to verify the design pressure under §195.106 or to perform the testing under paragraph (a)(4) of this section is unknown, the design pressure may be verified and the maximum operating pressure determined by—

(i) Testing the pipeline in accordance with ASME B31.8, Appendix N, to produce a stress equal to the yield strength; and

(ii) Applying, to not more than 80percent of the first pressure that produces a yielding, the design factor F in §195.106(a) and the appropriate factors in §195.106(e).

(2) The pipeline right-of-way, all aboveground segments of the pipeline,and appropriately selected underground segments must be visually inspected for physical defects and operating conditions which reasonably could be expected to impair the strength or tightness of the pipeline. (3) All known unsafe defects and conditions must be corrected in accordance with this part.

(4) The pipeline must be tested in accordance with subpart E of this part to substantiate the maximum operating pressure permitted by §195.406.

(b) A pipeline that qualifies for use under this section need not complywith the corrosion control requirements of subpart H of this part until 12 months after it is placed into service,notwithstanding any previous deadlines for compliance.

(c) Each operator must keep for thelife of the pipeline a record of the investigations, tests, repairs, replacements, and alterations made under the requirements of paragraph (a) of this section.

§ 195.6 Unusually Sensitive Areas (USAs).

As used in this part, a USA means a drinking water or ecological resourcearea that is unusually sensitive to environmental damage from a hazardous liquid pipeline release.

(a) An USA drinking water resource
is:

(1) The water intake for a Community Water System (CWS) or a Nontransient Non-community Water System (NTNCWS) that obtains its water supply primarily from a surface water source and does not have an adequate alternative drinking water source;

(2) The Source Water Protection Area (SWPA) for a CWS or a NTNCWS that obtains its water supply from a Class I or Class IIA aquifer and does not have an adequate alternative drinking watersource. Where a state has not yet identified the SWPA, the Wellhead Protection Area (WHPA) will be used until the state has identified the SWPA; or

(3) The sole source aquifer recharge area where the sole source aquifer is a karst aquifer in nature.

(b) An USA ecological resource is: (1) An area containing a criticallyimperiled species or ecological community;

(2) A multi-species assemblage area;


### 187 Pipeline and Hazardous Materials Safety Administration, DOT § 195.6

(3) A migratory waterbird concentration area;

(4) An area containing an imperiledspecies, threatened or endangered species, depleted marine mammal species, or an imperiled ecological community where the species or community isaquatic, aquatic dependent, or terrestrial with a limited range; or

(5) An area containing an imperiledspecies, threatened or endangered species, depleted marine mammal species, or imperiled ecological communitywhere the species or community occurrence is considered to be one of the most viable, highest quality, or in thebest condition, as identified by an element occurrence ranking (EORANK) ofA (excellent quality) or B (good quality).

(c) As used in this part— Adequate Alternative Drinking Water Source means a source of water that currently exists, can be used almost immediately with a minimal amount of effort and cost, involves no decline inwater quality, and will meet the consumptive, hygiene, and fire fighting requirements of the existing population of impacted customers for at least one month for a surface water source of water and at least six months for a groundwater source.

Aquatic or Aquatic Dependent Species or Community means a species or community that primarily occurs in aquatic, marine, or wetland habitats, as well as species that may use terrestrial habitats during all or some portion oftheir life cycle, but that are still closely associated with or dependent upon aquatic, marine, or wetland habitats for some critical component or portion of their life-history ( i.e., reproduction, rearing and development, feeding, etc).

Class I Aquifer means an aquifer that is surficial or shallow, permeable, and is highly vulnerable to contamination. Class I aquifers include:

(1) Unconsolidated Aquifers (Class Ia)that consist of surficial, unconsolidated, and permeable alluvial, terrace, outwash, beach, dune and other similardeposits. These aquifers generally contain layers of sand and gravel that,commonly, are interbedded to some degree with silt and clay. Not all Class Ia aquifers are important water-bearing units, but they are likely to be both permeable and vulnerable. The only natural protection of these aquifers is the thickness of the unsaturated zoneand the presence of fine-grained material;

(2) Soluble and Fractured Bedrock Aquifers (Class Ib). Lithologies in this class include limestone, dolomite, and, locally, evaporitic units that contain documented karst features or solution channels, regardless of size. Generallythese aquifers have a wide range of permeability. Also included in this classare sedimentary strata, and metamorphic and igneous (intrusive and extrusive) rocks that are significantly faulted, fractured, or jointed. In all cases groundwater movement is largely controlled by secondary openings. Well yields range widely, but the important feature is the potential for rapid vertical and lateral ground water movement along preferred pathways,which result in a high degree of vulnerability;

(3) Semiconsolidated Aquifers (Class Ic) that generally contain poorly to moderately indurated sand and gravel that is interbedded with clay and silt.This group is intermediate to the unconsolidated and consolidated end members. These systems are commonin the Tertiary age rocks that are exposed throughout the Gulf and Atlanticcoastal states. Semiconsolidated conditions also arise from the presence of intercalated clay and caliche within primarily unconsolidated to poorly consolidated units, such as occurs in parts of the High Plains Aquifer; or

(4) Covered Aquifers (Class Id) that are any Class I aquifer overlain by lessthan 50 feet of low permeability, unconsolidated material, such as glacial till, lacustrian, and loess deposits.

Class IIa aquifer means a Higher Yield Bedrock Aquifer that is consolidatedand is moderately vulnerable to contamination. These aquifers generally consist of fairly permeable sandstone or conglomerate that contain lesser amounts of interbedded fine grained clastics (shale, siltstone, mudstone) and occasionally carbonate units. Ingeneral, well yields must exceed 50 gallons per minute to be included in this class. Local fracturing may contribute to the dominant primary porosity and permeability of these systems.

EORANKs are assigned by the Natural Heritage Programs. An EORANK of A means an excellent quality and an EORANK of B means good quality.

Imperiled species or ecological community (habitat) means a rare species or ecological community, based on TheNature Conservancy’s Global Conservation Status Rank. There are generally 6 to 20 occurrences, or few remaining individuals (1,000 to 3,000) or acres(2,000 to 10,000). These species and ecological communities are vulnerable toextinction due to some natural or manmade factor.

Ramsar site means a site that has been designated under The Conventionon Wetlands of International Importance Especially as Waterfowl Habitat program. Ramsar sites are globallycritical wetland areas that support migratory waterfowl. These include wetland areas that regularly support 20,000waterfowl; wetland areas that regularly support substantial numbers of individuals from particular groups ofwaterfowl, indicative of wetland values, productivity, or diversity; and wetland areas that regularly support 1% of the individuals in a population of one species or subspecies of waterfowl.


### 189 Pipeline and Hazardous Materials Safety Administration, DOT § 195.8

Sole source aquifer (SSA) means anarea designated by the U.S. Environmental Protection Agency under the Sole Source Aquifer program as the ‘‘sole or principal’’ source of drinking water for an area. Such designations are made if the aquifer’s ground water supplies 50% or more of the drinking water for an area, and if that aquifer were to become contaminated, it would pose a public health hazard. A sole source aquifer that is karst in nature is one composed of limestone where theporosity is derived from connected solution cavities. They are often cavernous, with high rates of flow.

Source Water Protection Area (SWPA) means the area delineated by the state for a public water supply system (PWS) or including numerous PWSs, whether the source is ground water or surface water or both, as part of the state source water assessment program(SWAP) approved by EPA under section 1453 of the Safe Drinking Water

§ 195.102 Design temperature.

(a) Material for components of thesystem must be chosen for the temperature environment in which the components will be used so that the pipeline will maintain its structural integrity.

(b) Components of carbon dioxidepipelines that are subject to low temperatures during normal operation because of rapid pressure reduction or during the initial fill of the line must be made of materials that are suitable for those low temperatures.

[Admt. 195–45, 56 FR 26925, June 12, 1991]

§ 195.104 Variations in pressure.

If, within a pipeline system, two or more components are to be connected at a place where one will operate at ahigher pressure than another, the system must be designed so that any component operating at the lower pressure will not be overstressed.

§ 195.106 Internal design pressure.

(a) Internal design pressure for thepipe in a pipeline is determined in accordance with the following formula: P=(2 St/D ) × E× F

P =Internal design pressure in p.s.i. (kPa)

gage. S =Yield strength in pounds per square inch

(kPa) determined in accordance with paragraph (b) of this section.
t =Nominal wall thickness of the pipe in

inches (millimeters). If this is unknown, itis determined in accordance with paragraph (c) of this section.
D =Nominal outside diameter of the pipe in

inches (millimeters).
E =Seam joint factor determined in accordance with paragraph (e) of this section.
F =A design factor of 0.72, except that a design factor of 0.60 is used for pipe, including risers, on a platform located offshoreor on a platform in inland navigable waters, and 0.54 is used for pipe that has been subjected to cold expansion to meet the specified minimum yield strength and issubsequently heated, other than by welding or stress relieving as a part of welding, to a temperature higher than 900 ° F (482 ° C) for any period of time or over 600 ° F (316

° C) for more than 1 hour.

(b) The yield strength to be used indetermining the internal design pressure under paragraph (a) of this section is the specified minimum yield strength. If the specified minimum yield strength is not known, the yieldstrength to be used in the design formula is one of the following:

(1)(i) The yield strength determined by performing all of the tensile tests ofAPI Specification 5L on randomly selected specimens with the following number of tests:

Pipe size No. of tests

Less than 6 5 ⁄ 8 in (168 mm) nominal outside diameter. One test for each 200 lengths.
6 5

⁄ 8 in through 12 3 ⁄ 4 in (168 mmthrough 324 mm) nominal outside diameter. One test for each 100 lengths.

Larger than 12 3 ⁄ 4 in (324 mm)
nominal outside diameter. One test for each 50 lengths.

(ii) If the average yield-tensile ratio exceeds 0.85, the yield strength shall be taken as 24,000 p.s.i. (165,474 kPa). If the average yield-tensile ratio is 0.85 or less, the yield strength of the pipe is taken as the lower of the following:

(A) Eighty percent of the averageyield strength determined by the tensile tests.

(B) The lowest yield strength determined by the tensile tests.

(2) If the pipe is not tensile tested asprovided in paragraph (b) of this section, the yield strength shall be taken as 24,000 p.s.i. (165,474 kPa).

(c) If the nominal wall thickness to be used in determining internal design pressure under paragraph (a) of this section is not known, it is determined by measuring the thickness of each piece of pipe at quarter points on one end. However, if the pipe is of uniformgrade, size, and thickness, only 10 individual lengths or 5 percent of all lengths, whichever is greater, need be measured. The thickness of the lengths that are not measured must be verified by applying a gage set to the minimum thickness found by the measurement. The nominal wall thickness to be used is the next wall thickness found in commercial specifications that isbelow the average of all the measurements taken. However, the nominal wall thickness may not be more than 1.14 times the smallest measurement taken on pipe that is less than 20inches (508 mm) nominal outside diameter, nor more than 1.11 times the smallest measurement taken on pipe that is 20 inches (508 mm) or more in nominal outside diameter.


### 198 49 CFR Ch. I (10–1–10 Edition) § 195.108

(d) The minimum wall thickness ofthe pipe may not be less than 87.5 percent of the value used for nominal wall thickness in determining the internal design pressure under paragraph (a) ofthis section. In addition, the anticipated external loads and external pressures that are concurrent with internalpressure must be considered in accordance with §§195.108 and 195.110 and, after determining the internal design pressure, the nominal wall thicknessmust be increased as necessary to compensate for these concurrent loads and

pressures.

(e) The seam joint factor used inparagraph (a) of this section is determined in accordance with the following table:

An operator must promptly, but no later than 180days after an integrity assessment, obtain sufficient information about a condition to make that determination, unless the operator can demonstratethat the 180-day period is impracticable.

(3) Schedule for evaluation and remediation . An operator must complete remediation of a condition according to a schedule prioritizing the conditions forevaluation and remediation. If an operator cannot meet the schedule for any condition, the operator must explain the reasons why it cannot meet the schedule and how the changed schedulewill not jeopardize public safety or environmental protection.

(4) Special requirements for scheduling
remediation — (i) Immediate repair conditions. An operator’s evaluation and remediation schedule must provide forimmediate repair conditions.

### 227 Pipeline and Hazardous Materials Safety Administration, DOT § 195.452

(i) What preventive and mitigative measures must an operator take to protect the high consequence area? —(1) General requirements. An operator must take measures to prevent and mitigate the consequences of a pipeline failure that could affect a high consequence area. These measures include conducting a risk analysis of the pipeline segment to identify additional actions to enhancepublic safety or environmental protection. Such actions may include, but are not limited to, implementing damageprevention best practices, better monitoring of cathodic protection where corrosion is a concern, establishing shorter inspection intervals, installingEFRDs on the pipeline segment, modifying the systems that monitor pressure and detect leaks, providing additional training to personnel on response procedures, conducting drills with local emergency responders and adopting other management controls.

(2) Risk analysis criteria. In identifying the need for additional preventive and mitigative measures, an operator must evaluate the likelihood of a pipeline release occurring and how arelease could affect the high consequence area. This determination must consider all relevant risk factors, including, but not limited to:

(i) Terrain surrounding the pipeline segment, including drainage systemssuch as small streams and other smaller waterways that could act as a conduit to the high consequence area;

(ii) Elevation profile; (iii) Characteristics of the product transported;

(iv) Amount of product that could be released;

(v) Possibility of a spillage in a farmfield following the drain tile into a waterway;

(vi) Ditches along side a roadway the pipeline crosses;

(vii) Physical support of the pipeline segment such as by a cable suspension bridge;

(viii) Exposure of the pipeline to operating pressure exceeding established maximum operating pressure.

(3) Leak detection. An operator must have a means to detect leaks on its pipeline system. An operator mustevaluate the capability of its leak detection means and modify, as necessary, to protect the high consequence area. An operator’s evaluation must, at least, consider, the following factors— length and size of the pipeline, type ofproduct carried, the pipeline’s proximity to the high consequence area,the swiftness of leak detection, location of nearest response personnel, leak history, and risk assessment results.

(4) Emergency Flow Restricting Devices (EFRD). If an operator determines thatan EFRD is needed on a pipeline segment to protect a high consequence area in the event of a hazardous liquidpipeline release, an operator must install the EFRD. In making this determination, an operator must, at least, consider the following factors—the swiftness of leak detection and pipelineshutdown capabilities, the type of commodity carried, the rate of potentialleakage, the volume that can be released, topography or pipeline profile, the potential for ignition, proximity topower sources, location of nearest response personnel, specific terrain between the pipeline segment and thehigh consequence area, and benefits expected by reducing the spill size.

(j) What is a continual process of evaluation and assessment to maintain a pipeline’s integrity? —(1) General. After completing the baseline integrity assessment, an operator must continue to assess the line pipe at specified intervals and periodically evaluate the integrityof each pipeline segment that could affect a high consequence area.

(2) Evaluation. An operator must conduct a periodic evaluation as frequently as needed to assure pipeline integrity. An operator must base the frequency of evaluation on risk factors specific to its pipeline, including the factors specified in paragraph (e) ofthis section. The evaluation must consider the results of the baseline andperiodic integrity assessments, information analysis (paragraph (g) of thissection), and decisions about remediation, and preventive and mitigative actions (paragraphs (h) and (i) of this section).

(3) Assessment intervals . An operator must establish five-year intervals, not to exceed 68 months, for continually assessing the line pipe’s integrity. Anoperator must base the assessment intervals on the risk the line pipe poses


### 228 49 CFR Ch. I (10–1–10 Edition) § 195.452

to the high consequence area to determine the priority for assessing the pipeline segments. An operator must
establish the assessment intervalsbased on the factors specified in paragraph (e) of this section, the analysis ofthe results from the last integrity assessment, and the information analysisrequired by paragraph (g) of this section.

(4) Variance from the 5-year intervals in
limited situations —(i) Engineering basis. An operator may be able to justify anengineering basis for a longer assessment interval on a segment of linepipe. The justification must be supported by a reliable engineering evaluation combined with the use of othertechnology, such as external monitoring technology, that provides an understanding of the condition of the line pipe equivalent to that which can be
obtained from the assessment methodsallowed in paragraph (j)(5) of this section. An operator must notify OPS 270 days before the end of the five-year (or less) interval of the justification for alonger interval, and propose an alternative interval. An operator must send the notice to the address specified in paragraph (m) of this section.

(ii) Unavailable technology. An operator may require a longer assessment period for a segment of line pipe (forexample, because sophisticated internal inspection technology is not available). An operator must justify the reasons why it cannot comply with the required assessment period and must also demonstrate the actions it is taking to evaluate the integrity of the pipeline segment in the interim. An operator must notify OPS 180 days before the end of the five-year (or less) interval that the operator may require a longerassessment interval, and provide an estimate of when the assessment can be completed. An operator must send anotice to the address specified in paragraph (m) of this section.

(5) Assessment methods. An operator must assess the integrity of the line pipe by any of the following methods.The methods an operator selects to assess low frequency electric resistancewelded pipe or lap welded pipe susceptible to longitudinal seam failure must be capable of assessing seam integrity and of detecting corrosion and deformation anomalies.

(i) Internal inspection tool or toolscapable of detecting corrosion and deformation anomalies including dents, gouges and grooves;

(ii) Pressure test conducted in accordance with subpart E of this part;

(iii) External corrosion direct assessment in accordance with §195.588; or

(iv) Other technology that the operator demonstrates can provide anequivalent understanding of the condition of the line pipe. An operator choosing this option must notify OPS90 days before conducting the assessment, by sending a notice to the address or facsimile number specified in paragraph (m) of this section.

(k) What methods to measure program effectiveness must be used? An operator’s program must include methods tomeasure whether the program is effective in assessing and evaluating the integrity of each pipeline segment and in protecting the high consequence areas.See Appendix C of this part for guidance on methods that can be used to evaluate a program’s effectiveness.

(l) What records must be kept? (1) Anoperator must maintain for review during an inspection:

(i) A written integrity management program in accordance with paragraph (b) of this section.

(ii) Documents to support the decisions and analyses, including any modifications, justifications,variances, deviations and determinations made, and actions taken, to implement and evaluate each element of the integrity management program listed in paragraph (f) of this section.

(2) See Appendix C of this part for examples of records an operator would be required to keep.

RISDICTION —S TATEMENT OF A GENCY P OLICY AND I NTERPRETATION

In 1979, Congress enacted comprehensivesafety legislation governing the transportation of hazardous liquids by pipeline, the Hazardous Liquids Pipeline Safety Act of 1979, 49 U.S.C. 2001 et seq. (HLPSA). TheHLPSA expanded the existing statutory authority for safety regulation, which was limited to transportation by common carriers ininterstate and foreign commerce, to transportation through facilities used in or affecting interstate or foreign commerce. It also added civil penalty, compliance order, and injunctive enforcement authorities to the existing criminal sanctions. Modeled largely on the Natural Gas Pipeline Safety Act of 1968, 49 U.S.C. 1671 et seq. (NGPSA), the HLPSA provides for a national hazardousliquid pipeline safety program with nationally uniform minimal standards and with enforcement administered through a FederalState partnership. The HLPSA leaves to exclusive Federal regulation and enforcement the ‘‘interstate pipeline facilities,’’ thoseused for the pipeline transportation of hazardous liquids in interstate or foreign commerce. For the remainder of the pipeline facilities, denominated ‘‘intrastate pipeline facilities,’’ the HLPSA provides that the same Federal regulation and enforcement willapply unless a State certifies that it will assume those responsibilities. A certified State must adopt the same minimal standards butmay adopt additional more stringent standards so long as they are compatible. Therefore, in States which participate in the hazardous liquid pipeline safety programthrough certification, it is necessary to distinguish the interstate from the intrastate pipeline facilities.

In deciding that an administratively practical approach was necessary in distinguishing between interstate and intrastate liquid pipeline facilities and in determininghow best to accomplish this, DOT has logically examined the approach used in the
NGPSA. The NGPSA defines the interstate gas pipeline facilities subject to exclusive Federal jurisdiction as those subject to the


### 237 Pipeline and Hazardous Materials Safety Administration, DOT Pt. 195, App. A

economic regulatory jurisdiction of the Federal Energy Regulatory Commission (FERC).Experience has proven this approach practical. Unlike the NGPSA however, theHLPSA has no specific reference to FERC jurisdiction, but instead defines interstate liquid pipeline facilities by the more commonly used means of specifying the end points of the transportation involved. For example, the economic regulatory jurisdiction of FERC over the transportation of both gas and liquids by pipeline is defined in much the same way. In implementing the HLPSA DOThas sought a practicable means of distinguishing between interstate and intrastate pipeline facilities that provide the requisitedegree of certainty to Federal and State enforcement personnel and to the regulated entities. DOT intends that this statement of agency policy and interpretation provide that certainty.

In 1981, DOT decided that the inventory of liquid pipeline facilities identified as subject to the jurisdiction of FERC approximates the HLPSA category of ‘‘interstate pipeline facilities.’’ Administrative use of the FERC inventory has the added benefit of avoiding the creation of a separate Federal scheme for determination of jurisdiction over the same regulated entities. DOT recognizes that the FERC inventory is only an approximation and may not be totally satisfactory without some modification. The difficulties stemfrom some significant differences in the economic regulation of liquid and of natural gas pipelines. There is an affirmative assertion of jurisdiction by FERC over natural gas pipelines through the issuance of certificates of public convenience and necessity prior tocommencing operations. With liquid pipelines, there is only a rebuttable presumptionof jurisdiction created by the filing by pipeline operators of tariffs (or concurrences) formovement of liquids through existing facilities. Although FERC does police the filingsfor such matters as compliance with the general duties of common carriers, the question of jurisdiction is normally only aired upon complaint. While any person, includingState or Federal agencies, can avail themselves of the FERC forum by use of the complaint process, that process has only been rarely used to review jurisdictional matters (probably because of the infrequency of real disputes on the issue). Where the issue has arisen, the reviewing body has noted the need to examine various criteria primarily of an economic nature. DOT believes that, inmost cases, the formal FERC forum can better receive and evaluate the type of information that is needed to make decisions of this
nature than can DOT.

In delineating which liquid pipeline facilities are interstate pipeline facilities withinthe meaning of the HLPSA, DOT will generally rely on the FERC filings; that is, if
there is a tariff or concurrence filed with FERC governing the transportation of hazardous liquids over a pipeline facility or ifthere has been an exemption from the obligation to file tariffs obtained from FERC, thenDOT will, as a general rule, consider the facility to be an interstate pipeline facility within the meaning of the HLPSA. The types of situations in which DOT will ignore the existence or non-existence of a filing with FERC will be limited to those cases in which it appears obvious that a complaint filed with FERC would be successful or in which blind reliance on a FERC filing would result in a situation clearly not intended by the HLPSA such as a pipeline facility not beingsubject to either State or Federal safety regulation. DOT anticipates that the situationsin which there is any question about the validity of the FERC filings as a ready reference will be few and that the actual variations from reliance on those filings will be rare. The following examples indicate the types of facilities which DOT believes are interstate pipeline facilities subject to the HLPSA despite the lack of a filing with FERC and the types of facilities over which DOT will generally defer to the jurisdiction of a certifying state despite the existence of a filing with FERC.

Example 1. Pipeline company P operates a pipeline from ‘‘Point A’’ located in State Xto ‘‘Point B’’ (also in X). The physical facilities never cross a state line and do not connect with any other pipeline which does cross a state line. Pipeline company P also operates another pipeline between ‘‘Point C’’ in State X and ‘‘Point D’’ in an adjoining State Y. Pipeline company P files a tariff with FERC for transportation from ‘‘PointA’’ to ‘‘Point B’’ as well as for transportation from ‘‘Point C’’ to ‘‘Point D.’’ DOT will ignore filing for the line from ‘‘Point A’’ to ‘‘Point B’’ and consider the line to be
intrastate.

Example 2. Same as in example 1 except that P does not file any tariffs with FERC.DOT will assume jurisdiction of the line between ‘‘Point C’’ and ‘‘Point D.’’

Example 3. Same as in example 1 except
that P files its tariff for the line between ‘‘Point C’’ and ‘‘Point D’’ not only with FERC but also with State X. DOT will relyon the FERC filing as indication of interstate commerce.

Example 4. Same as in example 1 except that the pipeline from ‘‘Point A’’ to ‘‘PointB’’ (in State X) connects with a pipeline operated by another company transports liquid between ‘‘Point B’’ (in State X) and ‘‘Point D’’ (in State Y). DOT will rely on the FERC filing as indication of interstate commerce.

Example 5. Same as in example 1 except
that the line between ‘‘Point C’’ and ‘‘Point D’’ has a lateral line connected to it. The lateral is located entirely with State X. DOT will rely on the existence or non-existence of a FERC filing covering transportation over


### 238 49 CFR Ch. I (10–1–10 Edition) Pt. 195, App. B

that lateral as determinative of interstate

commerce.

Example 6. Same as in example 1 except that the certified agency in State X has brought an enforcement action (under the pipeline safety laws) against P because of its operation of the line between ‘‘Point A’’ and ‘‘Point B’’. P has successfully defended against the action on jurisdictional grounds. DOT will assume jurisdiction if necessary to avoid the anomaly of a pipeline subject to neither State or Federal safety enforcement. DOT’s assertion of jurisdiction in such a casewould be based on the gap in the state’s enforcement authority rather than a DOT decision that the pipeline is an interstate pipeline facility.

Example 7. Pipeline Company P operates apipeline that originates on the Outer Continental Shelf. P does not file any tariff for
that line with FERC. DOT will consider the pipeline to be an interstate pipeline facility.

Example 8. Pipeline Company P is constructing a pipeline from ‘‘Point C’’ (in StateX) to ‘‘Point D’’ (in State Y). DOT will consider the pipeline to be an interstate pipeline facility.

Example 9. Pipeline company P is constructing a pipeline from ‘‘Point C’’ to ‘‘Point E’’ (both in State X) but intends to file tariffs with FERC in the transportation of hazardous liquid in interstate commerce. Assuming there is some connection to aninterstate pipeline facility, DOT will consider this line to be an interstate pipeline facility.

Example 10. Pipeline Company P has operated a pipeline subject to FERC economic regulation. Solely because of some statutory economic deregulation, that pipeline is nolonger regulated by FERC. DOT will continue to consider that pipeline to be an interstate pipeline facility.

As seen from the examples, the types of
situations in which DOT will not defer to theFERC regulatory scheme are generally clearcut cases. For the remainder of the situations where variation from the FERC schemewould require DOT to replicate the forum already provided by FERC and to consider economic factors better left to that agency, DOT will decline to vary its reliance on the FERC filings unless, of course, not doing so would result in situations clearly not intended by the HLPSA.

R ISK -B ASED A LTERNATIVE

This Appendix provides guidance on how a risk-based alternative to pressure testing older hazardous liquid and carbon dioxide pipelines rule allowed by §195.303 will work.
This risk-based alternative establishes test priorities for older pipelines, not previously pressure tested, based on the inherent risk of a given pipeline segment. The first step is to
determine the classification based on the type of pipe or on the pipeline segment’s proximity to populated or environmentally sensitive area. Secondly, the classificationsmust be adjusted based on the pipeline failure history, product transported, and the release volume potential.

Tables 2–6 give definitions of risk classification A, B, and C facilities. For the purposes of this rule, pipeline segments containing high risk electric resistance-weldedpipe (ERW pipe) and lapwelded pipe manufactured prior to 1970 and considered a risk classification C or B facility shall be treated as the top priority for testing because of thehigher risk associated with the susceptibility of this pipe to longitudinal seam failures.

In all cases, operators shall annually, at intervals not to exceed 15 months, review
their facilities to reassess the classification and shall take appropriate action within two years or operate the pipeline system at a lower pressure. Pipeline failures, changes in the characteristics of the pipeline route, orchanges in service should all trigger a reassessment of the originally classification.

Table 1 explains different levels of test requirements depending on the inherent risk of a given pipeline segment. The overall risk
classification is determined based on the type of pipe involved, the facility’s location, the product transported, the relative volumeof flow and pipeline failure history as determined from Tables 2–6.

A Additional pressure testing not required.

1 If operational experience indicates a history of past failures for a particular pipeline segment, failure causes (time-dependen t defects due to corrosion, construction, manufacture, or transmission problems, etc.) shall be reviewed in determining risk clas sification (See Table 6) and the timing of the pressure test should be accelerated.

2 All pre-1970 ERW pipeline segments may not require testing. In determining which ERW pipeline segments should be included in this category, an operator must consider the seam-related leak history of the pipe and pipe manufacturing information as available, which may include the pipe steel’s mechanical properties, including fracture toughness; the manufacturing process and controls related to seam properties, including whether the ERW process was high-frequency or low-frequency, whether the weld seam was heat treated, whether the seam was inspected, the test pressure and duration during mill hydrotest; the quality control of the steel-making process; and other factors pertinent to seam properties and quality.

3 For those pipeline operators with extensive mileage of pre-1970 ERW pipe, any waiver requests for timing relief should be supported by an assessment of hazards in accordance with location, product, volume, and probability of failure considerations consistent with Tables 3, 4, 5, and 6.

4 A magnetic flux leakage or ultrasonic internal inspection survey may be utilized as an alternative to pressure testing where leak history and operating experience do not indicate leaks caused by longitudinal cracks or seam failures.

5 Pressure tests utilizing a hydrocarbon liquid may be conducted, but only with a liquid which does not vaporize rapidly.

Using LOCATION, PRODUCT, VOLUME, and FAILURE HISTORY ‘‘Indicators’’ from Tables 3, 4, 5, and 6 respectively, the overallrisk classification of a given pipeline or pipeline segment can be established from Table 2. The LOCATION Indicator is the primary factor which determines overall risk, withthe PRODUCT, VOLUME, and PROBABILITY OF FAILURE Indicators used toadjust to a higher or lower overall risk classification per the following table.

A PPENDIX C TO P ART 195—G UIDANCE FOR I MPLEMENTATION OF AN I NTEGRITY M ANAGEMENT P ROGRAM

This Appendix gives guidance to help an operator implement the requirements of the integrity management program rule in §§195.450 and 195.452. Guidance is provided on:

(1) Information an operator may use to identify a high consequence area and factors an operator can use to consider the potential impacts of a release on an area;

(2) Risk factors an operator can use to determine an integrity assessment schedule;

(3) Safety risk indicator tables for leak history, volume or line size, age of pipeline, and product transported, an operator may use to determine if a pipeline segment falls into a high, medium or low risk category;

(4) Types of internal inspection tools anoperator could use to find pipeline anomalies;

(5) Measures an operator could use to measure an integrity management program’s performance; and

(6) Types of records an operator will have
to maintain.

(7) Types of conditions that an integrity assessment may identify that an operator should include in its required schedule for
evaluation and remediation.

I. Identifying a high consequence area and factors for considering a pipeline segment’s potential impact on a high consequence area.

A. The rule defines a High ConsequenceArea as a high population area, an other populated area, an unusually sensitive area, or acommercially navigable waterway. The Office of Pipeline Safety (OPS) will map theseareas on the National Pipeline Mapping System (NPMS). An operator, member of the public or other government agency may view
and download the data from the NPMS home

page http://www.npms.phmsa.gov/. OPS willmaintain the NPMS and update it periodically. However, it is an operator’s responsibility to ensure that it has identified all high consequence areas that could be affected bya pipeline segment. An operator is also responsible for periodically evaluating its pipeline segments to look for population or environmental changes that may have occurred around the pipeline and to keep its program current with this information. (Refer to §195.452(d)(3).)

(1) Digital Data on populated areas available on U.S. Census Bureau maps.

(2) Geographic Database on the commercial navigable waterways available on http:// www.bts.gov/gis/ntatlas/networks.html.

(3) The Bureau of Transportation Statistics database that includes commercially navigable waterways and non-commercially


### 241 Pipeline and Hazardous Materials Safety Administration, DOT Pt. 195, App. C

navigable waterways. The database can be
downloaded from the BTS website at http:// www.bts.gov/gis/ntatlas/networks.html.

B. The rule requires an operator to include a process in its program for identifying which pipeline segments could affect a high consequence area and to take measures to prevent and mitigate the consequences of apipeline failure that could affect a high consequence area. (See §§195.452 (f) and (i).) Thus, an operator will need to consider how each pipeline segment could affect a high consequence area. The primary source for the listed risk factors is a US DOT study on instrumented Internal Inspection devices (November 1992). Other sources include the National Transportation Safety Board, the Environmental Protection Agency and the Technical Hazardous Liquid Pipeline Safety Standards Committee. The following list provides guidance to an operator on both the mandatory and additional factors:

(1) Terrain surrounding the pipeline. An operator should consider the contour of the land profile and if it could allow the liquid from a release to enter a high consequence area. An operator can get this informationfrom topographical maps such as U.S. Geological Survey quadrangle maps.

(2) Drainage systems such as small streams and other smaller waterways that could serve as a conduit to a high consequence

area.

(3) Crossing of farm tile fields. An operator should consider the possibility of a spillage in the field following the drain tile into a waterway.

(4) Crossing of roadways with ditches along the side. The ditches could carry a spillage to a waterway.

(5) The nature and characteristics of the product the pipeline is transporting (refined products, crude oils, highly volatile liquids, etc.) Highly volatile liquids becomes gaseous when exposed to the atmosphere. A spillage could create a vapor cloud that could settleinto the lower elevation of the ground profile.

(6) Physical support of the pipeline segment such as by a cable suspension bridge. An operator should look for stress indicatorson the pipeline (strained supports, inadequate support at towers), atmospheric corrosion, vandalism, and other obvious signs of improper maintenance.

(7) Operating conditions of the pipeline (pressure, flow rate, etc.). Exposure of the pipeline to an operating pressure exceedingthe established maximum operating pressure.

(8) The hydraulic gradient of the pipeline.(9) The diameter of the pipeline, the potential release volume, and the distance between the isolation points.

(10) Potential physical pathways between the pipeline and the high consequence area. (11) Response capability (time to respond, nature of response).

(12) Potential natural forces inherent inthe area (flood zones, earthquakes, subsidence areas, etc.)

II. Risk factors for establishing frequency
of assessment.

A. By assigning weights or values to therisk factors, and using the risk indicator tables, an operator can determine the priority for assessing pipeline segments, beginning with those segments that are of highest risk, that have not previously been assessed. This list provides some guidance on some of the risk factors to consider (see §195.452(e)). An operator should also develop factors specificto each pipeline segment it is assessing, including:

(1) Populated areas, unusually sensitive environmental areas, National Fish Hatcheries, commercially navigable waters, areas where people congregate.

(2) Results from previous testing/inspection. (See §195.452(h).)

(3) Leak History. (See leak history risk table.)

(4) Known corrosion or condition of pipeline. (See §195.452(g).)

(5) Cathodic protection history. (6) Type and quality of pipe coating (disbonded coating results in corrosion).

(7) Age of pipe (older pipe shows more corrosion—may be uncoated or have an ineffective coating) and type of pipe seam. (See Age of Pipe risk table.)

(8) Product transported (highly volatile, highly flammable and toxic liquids present agreater threat for both people and the environment) (see Product transported risk table.)

(9) Pipe wall thickness (thicker walls give a better safety margin)

(10) Size of pipe (higher volume release if the pipe ruptures).

(11) Location related to potential groundmovement (e.g., seismic faults, rock quarries, and coal mines); climatic (permafrostcauses settlement—Alaska); geologic (landslides or subsidence).

(12) Security of throughput (effects on customers if there is failure requiring shutdown).

(13) Time since the last internal inspection/ pressure testing.

(14) With respect to previously discovered defects/anomalies, the type, growth rate, and
size.

(15) Operating stress levels in the pipeline. (16) Location of the pipeline segment as itrelates to the ability of the operator to detect and respond to a leak. ( e.g., pipelines deep underground, or in locations that makeleak detection difficult without specific sectional monitoring and/or significantly impede access for spill response or any other purpose).


### 242 49 CFR Ch. I (10–1–10 Edition) Pt. 195, App. C

(17) Physical support of the segment such as by a cable suspension bridge.

(18) Non-standard or other than recognized industry practice on pipeline installation ( e.g., horizontal directional drilling).

B. Example: This example illustrates a hypothetical model used to establish an integrity assessment schedule for a hypothetical pipeline segment. After we determine therisk factors applicable to the pipeline segment, we then assign values or numbers to each factor, such as, high (5), moderate (3), or low (1). We can determine an overall risk classification (A, B, C) for the segment using the risk tables and a sliding scale (values 5 to 1) for risk factors for which tables are not provided. We would classify a segment as C if
it fell above 2 ⁄ 3 of maximum value (highest overall risk value for any one segment when compared with other segments of a pipeline), a segment as B if it fell between 1 ⁄ 3 to 2 ⁄ 3 ofmaximum value, and the remaining segments as A.

i. For the baseline assessment schedule, wewould plan to assess 50% of all pipeline segments covered by the rule, beginning with the highest risk segments, within the first
3 1

⁄ 2 years and the remaining segments withinthe seven-year period. For the continuing integrity assessments, we would plan to assess the C segments within the first two (2) years of the schedule, the segments classified as moderate risk no later than year three or four and the remaining lowest risk segments no later than year five (5).

ii. For our hypothetical pipeline segment, we have chosen the following risk factorsand obtained risk factor values from the appropriate table. The values assigned to the risk factors are for illustration only.
Age of pipeline: assume 30 years old (refer to

‘‘Age of Pipeline’’ risk table)—
Risk Value=5
Pressure tested: tested once during construction— Risk Value=5 Coated: (yes/no)—yes Coating Condition: Recent excavation of suspected areas showed holidays in coating (potential corrosion risk)—
Risk Value=5 Cathodically Protected: (yes/no)—yes—Risk

Value=1 Date cathodic protection installed: five years

after pipeline was constructed (Cathodic protection installed within one year of thepipeline’s construction is generally considered low risk.)—Risk Value=3 Close interval survey: (yes/no)—no—Risk

Value =5 Internal Inspection tool used: (yes/no)—yes.

Date of pig run? In last five years—Risk
Value=1 Anomalies found: (yes/no)—yes, but do not

pose an immediate safety risk or environmental hazard—Risk Value=3 Leak History: yes, one spill in last 10 years. (refer to ‘‘Leak History’’ risk table)—Risk
Value=2 Product transported: Diesel fuel. Product low

risk. (refer to ‘‘Product’’ risk table)—Risk
Value=1 Pipe size: 16 inches. Size presents moderate

risk (refer to ‘‘Line Size’’ risk table)—Risk
Value=3 iii. Overall risk value for this hypothetical segment of pipe is 34. Assume we have twoother pipeline segments for which we conduct similar risk rankings. The second pipeline segment has an overall risk value of 20, and the third segment, 11. For the baseline
assessment we would establish a schedule where we assess the first segment (highest risk segment) within two years, the secondsegment within five years and the third segment within seven years. Similarly, for the continuing integrity assessment, we could
establish an assessment schedule where we assess the highest risk segment no later than the second year, the second segment no later than the third year, and the third segment no later than the fifth year.

Comprehensive Environmental Response, Compensation and Liability Act Reportable Quantity values may be used as an indication of chronic toxicity. National Fire Protection Association health factors may be used for rating acute hazards.

IV. Types of internal inspection tools to

use.

An operator should consider at least twotypes of internal inspection tools for the integrity assessment from the following list. The type of tool or tools an operator selectswill depend on the results from previous internal inspection runs, information analysisand risk factors specific to the pipeline segment:

(1) Geometry Internal inspection tools for detecting changes to ovality, e.g., bends,dents, buckles or wrinkles, due to construction flaws or soil movement, or other outside force damage;

(2) Metal Loss Tools (Ultrasonic and Magnetic Flux Leakage) for determining pipewall anomalies, e.g., wall loss due to corrosion.

(3) Crack Detection Tools for detecting cracks and crack-like features, e.g., stress corrosion cracking (SCC), fatigue cracks, narrow axial corrosion, toe cracks, hook cracks, etc.

V. Methods to measure performance.
A. General. (1) This guidance is to help an operator establish measures to evaluate the effectiveness of its integrity managementprogram. The performance measures required will depend on the details of each integrity management program and will be based on an understanding and analysis ofthe failure mechanisms or threats to integrity of each pipeline segment.

(2) An operator should select a set of measurements to judge how well its program is performing. An operator’s objectives for its program are to ensure public safety, prevent or minimize leaks and spills and preventproperty and environmental damage. A typical integrity management program will be an ongoing program and it may containmany elements. Therefore, several performance measure are likely to be needed tomeasure the effectiveness of an ongoing program. B. Performance measures. These measuresshow how a program to control risk on pipeline segments that could affect a high consequence area is progressing under the integrity management requirements. Performance measures generally fall into three categories:

(1) Selected Activity Measures—Measures that monitor the surveillance and preventive activities the operator has implemented. These measure indicate how well an operator is implementing the various elements of its integrity management program.

(2) Deterioration Measures—Operation and
maintenance trends that indicate when the integrity of the system is weakening despitepreventive measures. This category of performance measure may indicate that the system condition is deteriorating despite well executed preventive activities.

(3) Failure Measures—Leak History, incident response, product loss, etc. These measures will indicate progress towards fewer spills and less damage.

C. Internal vs. External Comparisons. These comparisons show how a pipeline segment that could affect a high consequence area is progressing in comparison to the operator’s other pipeline segments that are not covered by the integrity management requirements and how that pipeline segment compares to other operators’ pipeline segments.

(1) Internal—Comparing data from the pipeline segment that could affect the high consequence area with data from pipeline segments in other areas of the system may indicate the effects from the attention given to the high consequence area.

(2) External—Comparing data external to the pipeline segment (e.g., OPS incidentdata) may provide measures on the frequency and size of leaks in relation to other companies.

D. Examples. Some examples of performance measures an operator could use include—

(1) A performance measurement goal to reduce the total volume from unintended releases by -% (percent to be determined by operator) with an ultimate goal of zero.

(2) A performance measurement goal to reduce the total number of unintended releases (based on a threshold of 5 gallons) by

ll -% (percent to be determined by operator) with an ultimate goal of zero.

(3) A performance measurement goal todocument the percentage of integrity management activities completed during the calendar year.

(4) A performance measurement goal to
track and evaluate the effectiveness of the operator’s community outreach activities.

(5) A narrative description of pipeline system integrity, including a summary of performance improvements, both qualitative and quantitative, to an operator’s integrity management program prepared periodically.


### 244 49 CFR Ch. I (10–1–10 Edition) Pt. 198

(6) A performance measure based on internal audits of the operator’s pipeline system per 49 CFR Part 195.

(7) A performance measure based on external audits of the operator’s pipeline system per 49 CFR Part 195.

(8) A performance measure based on operational events (for example: relief occurrences, unplanned valve closure, SCADA outages, etc.) that have the potential to adversely affect pipeline integrity.

(9) A performance measure to demonstrate that the operator’s integrity management program reduces risk over time with a focus on high risk items.

(10) A performance measure to demonstrate that the operator’s integrity management program for pipeline stations and
terminals reduces risk over time with a focus on high risk items.

VI. Examples of types of records an operator must maintain.

The rule requires an operator to maintain certain records. (See §195.452(l)). This section provides examples of some records that anoperator would have to maintain for inspection to comply with the requirement. This is
not an exhaustive list.

(1) a process for identifying which pipelines could affect a high consequence area and a document identifying all pipeline segments that could affect a high consequence area;

(2) a plan for baseline assessment of the line pipe that includes each required plan element;

(3) modifications to the baseline plan and reasons for the modification;

(4) use of and support for an alternative practice;

(5) a framework addressing each requiredelement of the integrity management program, updates and changes to the initial framework and eventual program;

(6) a process for identifying a new high consequence area and incorporating it into the baseline plan, particularly, a process for identifying population changes around a pipeline segment;

(7) an explanation of methods selected to assess the integrity of line pipe;

(8) a process for review of integrity assessment results and data analysis by a person qualified to evaluate the results and data;

(9) the process and risk factors for determining the baseline assessment interval;

(10) results of the baseline integrity assessment;

(11) the process used for continual evaluation, and risk factors used for determining the frequency of evaluation;

VII. Conditions that may impair a pipeline’s integrity.

Section 195.452(h) requires an operator to evaluate and remediate all pipeline integrity issues raised by the integrity assessment orinformation analysis. An operator must develop a schedule that prioritizes conditions discovered on the pipeline for evaluation andremediation. The following are some examples of conditions that an operator should
schedule for evaluation and remediation.

A. Any change since the previous assessment.

B. Mechanical damage that is located on the top side of the pipe.

C. An anomaly abrupt in nature. D. An anomaly longitudinal in orientation. E. An anomaly over a large area. F. An anomaly located in or near a casing, a crossing of another pipeline, or an area with suspect cathodic protection.
