WASHINGTON, DC 20590
In the Matter of
Marathon Ashland Pipe Line, LLC,
Respondent
CPF No. 5-2003-50I3
FINAL ORDER
On October 28-31, 2002, pursuant to 49 U S C ) 60117, a representative of the Office of
Pipelme Safety (OPS), Research and Special Programs Administration (RSPA), conducted an
on-site pipeline safety inspection of Respondent's Red Butte Pipe Line facilities from Silver Tip,
Montana, to Casper, Wyoming, and Respondent's manuals and records at its Powell and
Chatham, Wyoming offices. ' As a result of the inspection, the Director, Western Region, OPS,
issued to Respondent, by letter dated May 29, 2003, a Notice of Probable Violation, Proposed
Compliance Order, and Notice of Amendment (Notice) In accordance with 49 C F. R.
) 190. 207, the Notice proposed finding that Respondent had committed a violation of 49 C F. R
Part 195 and proposed that Respondent take certain measures to correct the alleged violation.
The Notice also proposed, in accordance with 49 C. F. R. ) 190. 237, that Respondent amend its
procedural manual for operations, maintenance and emergencies (OM&E).
After requesting and receiving an extension of time to respond, Respondent responded to the
Notice by letter dated July 18, 2003 (Response) Respondent contested several of the
allegations, offered information in explanation of the allegations, and provided information
concerning the corrective actions it has taken Respondent mitially requested a hearing; but
withdrew its request by letter dated June 23, 2004 Respondent submitted additional information
concerning the corrective actions it has taken by letter dated October 19, 2004
FINDING OF VIOLATION
Item 3 m the Notice alleged that Respondent violated 49 C F R $ 195 571 by failing to properly
The Norman Y. Mineta Researcli and Spn, ial Programs Iinprovement Act, Pub L. No 108-426,
118 Stat 2423 (2004), created the Pipeline and Hazardous Materials Safety Administration (PHMSA) and
transferred the authority of RSPA exercised under chapter 601 of title 49, United States Code, to the
Administrator of PHMSA See also 70 Fed. Reg 8299, 8301-8302 (2005).



consider voltage drop when measuring cathodic protection levels on the Red Butte Pipe Line
The Notice alleged that Respondent used a -850 mV criterion to conduct its 2002 cathodic
protection survey, but used an unacceptable method of considering voltage drop.
In its Response, Respondent contended that it complied with the requirements of 49 C. F R
) 195. 571 by using acceptable methods for considering voltage drop, including methods
recognized by NACE Standard RP0169-96 To support its claim, Respondent submitted sections
of its written procedures, inspection and testing reports, accounts of its corrosion control
programs, and other relevant documentation.
Section 195. 571 requires Respondent to ensure that its cathodic protection systems comply with
one or more of the applicable criteria contained in paragraphs 6. 2 and 6. 3 of NACE Standard
RP0169-96. Section 6. 2 of the Standard lists the -850 mV criterion for determimng whether
adequate levels of cathodic protection have been achieved, It also states that "voltage drops .
must be considered for valid interpretation of this voltage measurement. " The record shows that
Respondent used a -850 mV criterion to determine the adequacy of its cathodic protection system
during its 2002 annual cathodic protection survey. Accordingly, under ) 195, 571, Respondent
must determine the sigmficance of voltage drop in accordance with NACE Standard RP0169-96.
Respondent's procedural Standard No. MPLMNT-073 states that Respondent is to consider
voltage drop to interpret the potential or voltage measurement when using an "on" criterion, such
as the -850 mV criterion. Respondent's procedures list a number of methods for considering
voltage drop. Several of those methods are identical to those identified in NACE Standard
RP0169-96 for determimng voltage drop significance Despite Respondent's written procedures,
however, there is no indication that Respondent utilized any of those methods hsted in its
procedures during the 2002 cathodic protection survey The record shows that Respondent used
an IR free (IRF) reading during the 2002 survey, but the IRF reading alone is not an accepted
method for determining the significance of voltage drop, because the IRF reading is a pipe-to-
soil potential reading taken on the ground surface directly above the pipeline with the cathodic
protection rectifiers operating uninterrupted. When the readmg is taken with the rectifier
operatmg uninterrupted, the volt meter may not accurately discern the difference between the
'
potential voltage and the IR voltage
I his can cause the reading to appear more negative than the
potential readmg alone. Therefore, the IRF reading alone is not an accurate or acceptable
method for determining the significance of voltage drop
The record shows that Respondent also considered voltage drop during individual pipeline
inspections, noted on Respondent's "Land and Pipe Management Reports*' However, these
reports are inconclusive to show that Respondent utilized an accepted method for determining
voltage drop significance. The reports do not indicate the criterion that had been used to
consider voltage drop. In addition, the reports were not completed as part of a cathodic
protection survey; rather they were completed during separate and distinct inspections at
individual sites along the pipeline,
In its response, Respondent further contended that it used the 100 mV criterion at various
locations along the pipeline during 2001 and 2002. According to Respondent, this method



3
enabled Respondent to consider voltage drop by direct measurement calculations. While
section 6. 2 of the NACE Standard RP0169-96 recogmzes the 100 mV )riterion as an acceptable
method to determine the adequacy of cathodic protection, Respondent did not document use of
this method on the entire pipeline Respondent's test records show that Respondent used the 100
mV criterion at isolated locations along the line Therefore, Respondent's use of the 100 mV
criterion did not determine the adequacy of Respondent's cathodic protection or the significance
of voltage drop for the entire pipeline
Respondent provided documentation that it had installed a number of metal coupon test stations
These test stations are capable of measuring soil potentials with the cathodic protection current
interrupted. The coupon test stations appear to be acceptable methods for considering voltage
drop; but Respondent had not installed the coupons at every test station on the line.
While Respondent has taken a number of steps to consider voltage drop and determine the
adequacy of its cathodic protection system, I find Respondent failed to document the use of an
accepted method to consider the significance of voltage drop on the entire Red Butte Pipe Line
Accordingly, I find that Respondent violated 49 C F R g 195 571 as alleged in the Notice
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 3 of the Notice. Under 49 U. S C
) 60118(a), each person who engages in the transportation of hazardous liquids or who owns or
operates a pipeline facility is required to comply with the applicable safety standards established
under Chapter 601. The Director, Western Region, OPS has mdicated that Respondent has taken
the following actions specified m the Proposed Comphance Order.
Respondent implemented a new format for annual cathodic protection surveys that
documents the critenon, targets and actual readings to assure that IR drop consideration is
completed and documented. Respondent developed target "on" readings for each test
station and completed a comprehensive cathodic protection survey.
Accordingly, since compliance has been achieved with respect to this violation, it is not
necessary to include the compliance terms in this Order.
AMENDMENT OF PROCEDURES
Item 1 in the Notice alleged inadequacies in Respondent's OMBRE manual and proposed to
require amendment of Respondent's procedures to comply with the requirements of 49 C. F R
g 195, 402(f) and 195 55
Section 195 402(f) requires Respondent to have procedures for personnel to recognize safety-
related conditions subject to reporting under $ 195 55 Surges in pipeline pressure in excess of



110% of the maximum operating pressure is a safety-related condition that must be reported in
accordance with $ 195 55. The Notice alleged that Respondent's procedures listed this condition
as an abnormal operation, not a reportable safety-related condition.
In its Response, Respondent admitted that its "Standard Procedures" listed Lhe condition as an
abnormal operation, but argued that another portion of its OM&E manual titled "Safety-Related
Conditions" listed the condition as a safety-related condition in accordance with $ 195 402(f)
Therefore, Respondent contended, it complied with $ 195 402(f) and the inadequacy alleged in
the Notice should be withdrawn.
Although Respondent properly listed the condition as a reportable safety-related condition, the
condition was also listed elsewhere in its OMBRE manual as an abnormal operation. Respondent
had not cross-referenced the two sections. Were personnel to consult "Standard Procedures'*
only, they would recognize the condition as an abnormal operation, rather than a reportable
safety-related condition. Respondent agreed that clarification and cross-referencing would be
beneficial.
Respondent submitted copies of its amended procedures, which the Director, Western Region,
OPS, reviewed Based on the results of this review, I find that Respondent's original procedures
as described in the Notice were inadequate to ensure safe operation of its pipeline system, but
that Respondent has corrected the identified inadequacies Therefore, no need exists to issue an
order directing amendment.
WARNING ITEM
The Notice did not propose a civil penalty or corrective action for Item 2 of the Notice, but
warned Respondent that it should take appropriate corrective action to correct the item The
warning was for:
49 C. F R. $ 195. 569 — failing to examine exposed portions of bur~ed pipeline for
evidence of external corrosion.
In its Response, Respondent presented mformation showing that it has addressed this item.
Respondent is again warned that if OPS finds a violation for the cited item in a subsequent
inspection, enforcement action will be taken
The terms and conditions of this Final Order are effective on receipt
