FINAL ORDER
From January 9 through May 24, 2017, 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 on-site pipeline safety inspection of the facilities and records of Enterprise
Products Operating, LLC (EPO or Respondent), in Houston, Texas. EPO is a wholly-owned
subsidiary of Enterprise Partners, LP. (Enterprise).1 Enterprise conducts substantially all of its
operations through EPO, including approximately 50,000 miles of pipeline and 260 million
barrels of hazardous liquid storage capacity.2
As a result of the inspection, the Director, Southwest Region, OPS (Director), issued to
Respondent, by letter dated May 3, 2018, a Notice of Probable Violation and Proposed
Compliance Order (Notice). In accordance with 49 C.F.R. § 190.207, the Notice proposed
finding that EPO had violated 49 C.F.R. § 195.575(e) and proposed ordering Respondent to take
certain measures to correct the alleged violation.
EPO responded to the Notice by letter dated June 7, 2018 (Response). The company contested
the allegation, offered additional information in response to the Notice, and provided information
concerning the corrective actions it had taken. Respondent did not request a hearing and
therefore has waived its right to one.

FINDING OF VIOLATION
The Notice alleged that Respondent violated 49 C.F.R. Part 195, as follows:
Item 1: The Notice alleged that Respondent violated 49 C.F.R. § 195.575(e), which states:
§ 195.575 Which facilities must I electrically isolate and what inspections,
tests, and safeguards are required?
(e) If a pipeline is in close proximity to electrical transmission tower footings,
ground cables, or counterpoise, or in other areas where it is reasonable to foresee
fault currents or an unusual risk of lightning, you must protect the pipeline against
damage from fault currents or lightning and take protective measures at insulating
devices.
The Notice alleged that Respondent violated 49 C.F.R. § 195.575(e) by failing to evaluate the
potential threat of fault currents and lightning on one of the company’s pipeline systems.
Specifically, the Notice alleged that the Chaparral pipeline system was observed to be in close
proximity to high voltage electrical transmission power lines (HVPLs) for “a considerable length
of miles between Mont Belvieu and Bryan, Texas.” EPO failed to provide any records
demonstrating that the Chaparral system was protected from damage. Additionally, EPO stated
to OPS inspectors that no fault analysis or engineering analysis had been performed on the
Chaparral line to evaluate the potential for damage from fault currents and lightning.3
In its Response, EPO did not contest that its actions constituted a violation of Part 195, but
argued that PHMSA should have cited the company for a violation of 49 C.F.R. § 195.402(c)(3),
rather than § 195.575(e). Respondent raised four interrelated arguments against the proposed
violation: (1) OPS did not prove that the Chaparral line was in close proximity to an HVPL; (2)
an analysis of potential fault current or lightning damage was not required by § 195.575(e); (3)
EPO’s pre-PHMSA inspection maintenance activities and records reviews demonstrated that the
pipeline did not require protective measures against damage from fault currents or lightning; and
(4) EPO’s post-PHMSA inspection soil-resistivity measurements further demonstrated that the
pipeline did not require protective measures against damage from fault currents or lightning.
With respect to EPO’s first argument, the company argues that PHMSA has never explained
what constitutes “close proximity” under § 195.575(e); it also argues that PHMSA offered “no
evidence of the distance between the Chaparral line and the HVPL.”4 Both Respondent and OPS
cite to a 1998 PHMSA interpretation of 49 C.F.R. § 192.467(f), a substantively-identical
regulation applicable to operators of natural gas pipelines.5 In that interpretation, PHMSA
stated, in relevant part: “’close proximity’ means near enough to the listed structures to
reasonably expect that a lightning strike or fault current involving the structure might harm the
pipeline's corrosion control system. Close proximity is not an absolute or minimum distance,

and it could vary depending on site conditions.”6 In the instant case, OPS made a factual
determination that the Chaparral line was in close proximity to an HVPL “for a considerable
length of miles.”
Respondent cites a PHMSA enforcement case, In the matter of Golden Pass Pipeline, LLC
(Golden Pass),7 to suggest that factual statements made by OPS in the Notice and the VR must
be corroborated with additional evidence to overcome an operator’s statements to the contrary.
In Golden Pass, the alleged violation was withdrawn because OPS did not offer any additional
evidence (e.g., photographs or maps) to support its interpretation of a definition in an industry
standard.8 Respondent recognizes that “close proximity” is not defined in terms of “an absolute
or minimal distance,” and offers no evidence to contest OPS’ factual assertion that the pipeline
was in close proximity to an HVPL.9 Given the lack of evidence countering OPS’ credible
factual statement, and both parties’ reliance on PHMSA’s analogous interpretation of
§ 192.467(f), Respondent’s argument that OPS was required to demonstrate some specific set of
additional facts in order to sustain a violation of § 195.575(e) is without merit.
I also note that both parties cite to a 2017 PHMSA Notice of Amendment, In the Matter of
Williams Olefins Feedstock Pipelines, LLC (Williams), for the proposition that an operator must
first evaluate “when protection against damage from fault currents or lightning is needed” in
order to determine whether action is required to comply with § 195.575(e).10 Exhibit A to EPO’s
Response, Enterprise’s Procedure CPP-GEN-06, specifies that pipelines “located within or near
HVPL corridors may be at risk” of fault current or lightning damage, and that HVPLs
“collocated in the same [right-of-way] ROW or in close proximity to a pipeline” may cause
damage.11 Exhibit P contains photographs of HVPL tower footings that Respondent describes as
collocated with the Chaparral line.12 In the Response, EPO lists a variety of records and data that
it reviewed to determine whether the line was subject to potential damage from fault currents and

Pipelines, §§ 2.1, 3.1 (rev. Apr. 19, 2018). Respondent noted in the Response that, prior to the PHMSA inspection,
“the Company did not have a document summarizing the actions it takes to determine if a pipeline is in close
proximity to a HVPL and whether additional protection was necessary,” but claimed that the actions required in
CPP-GEN-06 were “incorporated in other individual procedures.” Response at 2.

lightning.13 Given that Enterprise clearly considers collocation of its pipelines with HVPLs to be
a risk-factor for fault current or lightning damage, and the presented evidence that the Chaparral
line is collocated with HVPLs, it is unclear why Respondent is contesting OPS’s factual
determination that Chaparral line is in close proximity to HVPLs. Issues concerning the type of
analysis or evaluation necessary to determine whether a pipeline in close proximity to an HVPL
or other structures listed in § 195.575(e) must have additional protection are addressed in
response to Respondent’s second argument, below.
In Respondent’s second argument, it argues that PHMSA is attempting to require operators to
conduct an engineering analysis not contemplated by § 195.575(e) when evaluating the threat of
fault current and lightning damage.14 This is not the case. In the Notice and the VR, OPS
alleged that EPO failed to evaluate the potential threat of fault current and lightning damage and,
in the absence of evidence that a line in close proximity to an HVPL was not subject to such
damage, failed to demonstrate that said line was protected. OPS did not assert any requirement
to conduct a particular engineering analysis. In light of Williams and related PHMSA guidance,
an operator must determine whether a line in close proximity to listed structures is subject to
potential damage from fault currents and lightning. Respondent’s assertions that its pre-
inspection activities were sufficient to demonstrate the Chaparral line was not subject to potential
damage are addressed in response to its third argument, below.
With respect to the third argument, Respondent alleges that it took several steps to evaluate the
potential threat of fault currents and lightning on the Chaparral line, prior to the PHMSA
inspection. Specifically, EPO argues that it evaluated the potential threats “through evaluating
operational data and assessment records.”15 The company alleges that this data and records
review “demonstrated that the Chaparral Pipeline is not in close proximity to an HVPL to trigger
the need for additional protective measures under § 195.575(e).”16 However, the records
provided as exhibits to the Response simply describe the type of coating used on the line, note
the results of prior cathodic-protection surveys, and observe that the line has not previously
shown any signs of fault current or lightning-related damage. There is no evidence to
demonstrate that Respondent conducted an evaluation of whether the Chaparral line was at risk
of damage from fault currents or lightning, sufficient to justify the lack of protection required by
§ 195.575(e).
With respect to the final argument, EPO’s May 2017 taking of soil-resistivity measurements17
was an action taken during and after the PHMSA inspection to comply with the requirements of
§ 195.575(e). The additional data and arguments in the Response constitute post hoc attempts to
13 Response at 7 (describing, however, the review for potential fault current and lightning damage as one to
determine “close proximity to an HVPL,” rather than a review of data for a line that is already determined to be in
close proximity).

justify Respondent’s decision to not provide protection against damage from fault currents or
lightning. After PHMSA discovers a violation of the Pipeline Safety Regulations, subsequent
operator actions to come into compliance do not warrant the withdrawal of the proposed
violation. Furthermore, the soil-resistivity measurements and other data provided in the
Response still do not contain any computation of AC voltage and AC current densities on the
Chaparral line or any other analysis as to whether additional protection is needed.
Accordingly, after considering all of the evidence and the arguments presented, I find that
Respondent violated 49 C.F.R. § 195.575(e) by failing to evaluate the potential threat of fault
currents and lightning on one of the company’s pipeline systems.
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 violation of 49
C.F.R. §§ 195.575(e). 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.
With regard to the violation of § 195.575(e) (Item 1), Respondent argued the compliance terms
should be considered satisfied in light of its April 2018 revisions to Procedure CPP-GEN-06, AC
Fault and Lightning Evaluation for Existing Pipelines. As currently written, CPP-GEN-06 does
not provide sufficient detail, or reference other procedures or standards, that the operator can use
to determine if its pipelines are in close proximity to an HVPL and whether any additional
protection against fault currents or lightning is required. Additionally, CPP-GEN-06 does not
require Enterprise to maintain records sufficient to allow proper evaluation in § 2.0 of the
procedure.
For the above reasons, the Compliance Order is not withdrawn or considered satisfied.
Pursuant to the authority of 49 U.S.C. § 60118(b) and 49 C.F.R. § 190.217, Respondent is
ordered to take the following actions to ensure compliance with the pipeline safety regulations
applicable to its operations:
1. With respect to the violation of § 195.575(e) (Item 1), Respondent must review its
procedure, CPP-GEN-06, AC Fault and Lightning Evaluation for Existing Pipelines,
to ensure that the procedure provides adequate guidance, details, and a method for
recording how existing pipelines are being evaluated for their protection against the
threat of AC fault currents and lightning. Respondent must also provide a copy of the
management-of-change (MOC) documentation that shows the procedure is effective
and the date it became effective. Respondent shall submit the revised procedure and
MOC documentation to PHMSA no later than 30 days from issuance of this Final
Order.



CPF 4-2018-5009
Page 6
The Director may grant an extension of time to comply with any of the required items upon a
written request timely submitted by the Respondent and demonstrating good cause for an
extension.
It is requested (not mandated) that Respondent maintain documentation of the safety
improvement costs associated with fulfilling this Compliance Order and submit the total to the
Director. It is requested that these costs be reported in two categories: (1) total cost associated
with preparation/revision of plans, procedures, studies and analyses; and (2) total cost associated
with replacements, additions and other changes to pipeline infrastructure.
Failure to comply with this Order may result in the administrative assessment of civil penalties
not to exceed $200,000, as adjusted for inflation (49 C.F.R. § 190.223), for each violation for
each day the violation continues or in referral to the Attorney General for appropriate relief in a
district court of the United States.
Under 49 C.F.R. § 190.243, Respondent may submit a Petition for Reconsideration of this Final
Order to the Associate Administrator, Office of Pipeline Safety, PHMSA, 1200 New Jersey
Avenue, SE, East Building, 2nd Floor, Washington, DC 20590, with a copy sent to the Office of
Chief Counsel, PHMSA, at the same address, no later than 20 days after receipt of service of this
Final Order by Respondent. Any petition submitted must contain a statement of the issue(s) and
meet all other requirements of 49 C.F.R. § 190.243. The terms of the order, including corrective
action, remain in effect unless the Associate Administrator, upon request, grants a stay.
The terms and conditions of this Final Order are effective upon service in accordance with 49
C.F.R. § 190.5.
