FINAL ORDER
Between September 10 to 14, September 24 to 26, and on December 6, 2007, pursuant to 49
U.S.C. § 60117, a representative of the Pipeline and Hazardous Materials Safety Administration
(PHMSA), Office of Pipeline Safety (OPS), conducted an inspection of the integrity
management program (IMP) of ONEOK Partners, L.P. (ONEOK or Respondent). The
inspection occurred at Respondent’s facilities in Tulsa, Oklahoma, and El Paso, Texas, and
included a reviewed of the IMP for the OKTex and Norteno pipelines, both of which are owned
and operated by ONEOK. In total, Respondent owns and operates approximately 1,290 miles of
interstate natural gas pipelines across thirteen states, as well as numerous natural gas storage
facilities.
As a result of the inspection, the Director, Southwest Region, OPS (Director), issued to ONEOK,
by letter dated March 14, 2008, a Notice of Probable Violation and Proposed Compliance Order
(Notice). In accordance with 49 C.F.R. § 190.207, the Notice proposed finding that ONEOK had
violated 49 C.F.R § 192.619 and ordering Respondent to take certain measures to correct the
alleged violation.
ONEOK responded to the Notice by letters dated April 16, August 13, and August 28, 2008
(collectively, Response). Respondent did not contest the allegation of violation but instead
described corrective actions it planned to implement. ONEOK did not request a hearing and
therefore has waived its right to one.
FINDING OF VIOLATION
Item 1: The Notice alleged that ONEOK violated 49 C.F.R. § 192.619, which states:



2
§ 192.619 Maximum allowable operating pressure: Steel or plastic
pipelines.
(a) Except as provided in paragraph (c) of this section, no person
may operate a segment of steel or plastic pipeline at a pressure that
exceeds the lowest of the following:
(1) The design pressure of the weakest element in the segment,
determined in accordance with subparts C and D of this part. However,
for steel pipe in pipelines being converted under §192.14 or uprated under
subpart K of this part, if any variable necessary to determine the design
pressure under the design formula (§ 192.105) is unknown, one of the
following pressures is to be used as design pressure:
(i) Eighty percent of the first test pressure that produces yield under
section N5 of Appendix N of ASME B31.8 (incorporated by reference, see
§ 192.7), reduced by the appropriate factor in paragraph (a)(2)(ii) of this
section; or
(ii) If the pipe is 12 ¾ inches (324 mm) or less in outside diameter
and is not tested to yield under this paragraph, 200 p.s.i. (1379 kPa).
(2) The pressure obtained by dividing the pressure to which the
segment was tested after construction as follows:
(i) For plastic pipe in all locations, the test pressure is divided by a
factor of 1.5.
(ii) For steel pipe operated at 100 p.s.i. (689 kPa) gage or more, the
test pressure is divided by a factor determined in accordance with the
following table:
Factors1
, segment—
Class
location
Installed before
(Nov. 12, 1970)
Installed after
(Nov. 11, 1970)

§192.14
1 1.1 1.1 1.25
2 1.25 1.25 1.25
3 1.4 1.5 1.5
4 1.4 1.5 1.5
1 For offshore segments installed, uprated or converted after July 31, 1977, that are not located on an
offshore platform, the factor is 1.25. For segments installed, uprated or converted after July 31, 1977, that
are located on an offshore platform or on a platform in inland navigable waters, including a pipe riser, the
factor is 1.5.



3
(3) The highest actual operating pressure to which the segment was
subjected during the 5 years preceding the applicable date in the second
column. This pressure restriction applies unless the segment was tested
according to the requirements in paragraph (a)(2) of this section after the
applicable date in the third column or the segment was uprated according
to the requirements in subpart K of this part:
Pipeline segment Pressure date Test date
Onshore gathering line that first
became subject to this part (other
than §192.612) after April 13, 2006
Onshore transmission line that was
a gathering line not subject to this
part before March 15, 2006
March 15, 2006, or date line
becomes subject to this part,
whichever is later.
5 years
preceding
applicable date
in second
column.
Offshore gathering lines July 1, 1976 July 1, 1971.
All other pipelines July 1, 1970 July 1, 1965.
(4) The pressure determined by the operator to be the maximum safe
pressure after considering the history of the segment, particularly known
corrosion and the actual operating pressure.
(b) No person may operate a segment to which paragraph (a)(4) of
this section is applicable, unless over-pressure protective devices are
installed on the segment in a manner that will prevent the maximum
allowable operating pressure from being exceeded, in accordance with
§192.195.
(c) The requirements on pressure restrictions in this section do not
apply in the following instance. An operator may operate a segment of
pipeline found to be in satisfactory condition, considering its operating
and maintenance history, at the highest actual operating pressure to which
the segment was subjected during the 5 years preceding the applicable
date in the second column of the table in paragraph (a)(3) of this section.
An operator must still comply with §192.611.
(d) The operator of a pipeline segment of steel pipeline meeting the
conditions prescribed in §192.620(b) may elect to operate the segment at a
maximum allowable operating pressure determined under §192.620(a).2
2 This regulation was amended by final rule, effective December 1, 2008, to include section (d). See Pipeline Safety:
Standards for Increasing the Maximum Allowable Operating Pressure for Gas Transmission Pipelines, 73 Fed. Reg.
62148 (October 17, 2008) and 73 Fed. Reg. 72737(November 17, 2008) (codified at 49 C.F.R. 192.619). This
addition does not affect the violation alleged in the March 14, 2008 Notice.



4
The Notice alleged that ONEOK violated § 192.619 by failing to establish the maximum
allowable operating pressure (MAOP) for three segments of the Norteno Pipeline. Specifically,
the Notice alleged that Respondent could not show that it had properly established the MAOP for
the Norteno #1, Norteno #4, and Norteno #5 segments by taking into account all of the factors
listed in the regulation, including the design pressure of the weakest element in the segment,
certain test pressures, and the historical operating pressure of the line. The regulation requires
that the MAOP of a segment be established using these factors to ensure that Respondent is not
operating the line at an unsafe pressure. Operating a line at an unsafe pressure could cause a
potential pipeline leak or rupture and adversely impact public safety and the environment.
Respondent did not contest this violation and accepted the terms of the proposed compliance
order. Accordingly, I find that Respondent violated 49 C.F.R. § 192.619 by failing to establish
the MAOP for certain segments of the Norteno Pipeline.
This finding of violation will be considered a prior offense in any subsequent enforcement action
taken against Respondent.
COMPLIANCE ORDER
The Notice proposed a compliance order with respect to Item 1 in the Notice for violating 49
C.F.R. § 192.619. Under 49 U.S.C. § 60118(a), each person who engages in the transportation
of gas or who owns or operates a pipeline facility is required to comply with the applicable
safety standards established under chapter 601. The Director has indicated that Respondent has
demonstrated completion of the actions listed in the proposed compliance order:
1. Item 1 of the Proposed Compliance Order directed ONEOK to establish the MAOP of the
Norteno #1 pipeline based upon the requirements of § 192.619. Respondent provided
documentation of a July 19, 2007 eight-hour pressure test to 688 psig on the 12” Norteno
#1 line (segments #1, #2, and #3) to establish the MAOP at 454 psig for these Class 2 and
3 segments.
The Norteno #1 Pipeline, segment #4, was pressure tested to 499 psig on July 15, 2008,
to establish a MAOP of 454 psig for this Class 1 segment. Respondent submitted a
pressure test plan to OPS that included a review of the existing materials, operating
history, test limits, leak history, survey requirements and pressure test criteria. These
materials were deemed acceptable under § 192.619.
2. Item 2 of the Proposed Compliance Order directed ONEOK to provide documentation for
the MAOP for Norteno Pipelines, #1, #4, and #5. ONEOK submitted the documentation
to support the pressure tests that occurred on July 19, 2007 (Norteno #1), November 5-8,
2007 (Norteno #s 4 & 5), and July 15, 2008 (Norteno #1, segment #4).
• Norteno #1: 454 psig
• Norteno #4: El Paso RP to Canutillo DP-252 psig



5
• Norteno #4: Canutillo DP to end of line-104 psig
• Norteno #4: Gillette Road Lateral-104 psig
• Norteno #5: 61 psig
These materials were deemed acceptable under § 192.619.
3. Respondent provided proof to the Director of the safety improvement costs totaling
$29,104.08.
Since compliance has been achieved with respect to this violation, it is unnecessary to include
the compliance terms in this Order.
The terms and conditions of this Final Order shall be effective upon receipt.
