WARNING LETTER
VIA ELECTRONIC MAIL TO: gbacon@eprod.com
October 12, 2023
Graham Bacon
Executive Vice President and Chief Operating Officer
Enterprise Products Operating, LLC
1100 Louisiana Street
Houston Texas 77002
CPF 4-2023-058-WL
Dear Mr. Bacon:
From August 28 through August 31, 2023, representatives of the Pipeline and Hazardous Materials
Safety Administration (PHMSA), Office of Pipeline Safety, pursuant to Chapter 601 of 49 United
States Code (U.S.C.) inspected Enterprise Products Operating, LLC’s (Enterprise) facilities being
constructed or modified at Mont Belvieu, Texas, and Hobbs, New Mexico, as part of its flow reversal
project.
As a result of the inspection, it is alleged that Enterprise has committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (C.F.R.). The items inspected and
the probable violations are:
1. § 195.202 Compliance with specifications or standards.
Each pipeline system must be constructed in accordance with
comprehensive written specifications or standards that are consistent with
the requirements of this part.
Enterprise failed to construct its pipeline system in accordance with comprehensive written
specifications or standards that are consistent with the construction requirements of Part 195 as
required by § 195.202. Specifically, Enterprise failed to perform a review of the subsurface
conditions to determine the risks associated with hydrofracturing and inadvertent returns and had
not determined whether the factors of safety were acceptable as required by the Enterprise Products
Engineering Standard, STD.8709, Horizontal Directional Drilling, Rev. 2.1, section 4.1.(2).



During the inspection, PHMSA requested records documenting this review of the subsurface
conditions and determination of the safety factor for the Horizontal Direction Drill, but Enterprise
failed to provide any supporting documentation.
2. § 195.202 Compliance with specifications or standards.
Each pipeline system must be constructed in accordance with
comprehensive written specifications or standards that are consistent with
the requirements of this part.
Enterprise failed to construct its pipeline system in accordance with comprehensive written
specifications or standards that are consistent with the construction requirements of Part 195 as
required by § 195.202. Specifically, Enterprise failed to require its contractor to provide a written
description of the equipment, methods, and procedures for completion prior to commencement of
work as required by the Enterprise Products Engineering Standard, STD.8709, Horizontal
Directional Drilling, Rev. 2.1, section 4.2. During the inspection, PHMSA requested records
documenting the equipment, methods, and procedures for performing the work associated with the
Horizontal Directional Drill, but Enterprise failed to provide any supporting documentation.
3. § 195.202 Compliance with specifications or standards.
Each pipeline system must be constructed in accordance with
comprehensive written specifications or standards that are consistent with
the requirements of this part.
Enterprise failed to construct its pipeline system in accordance with comprehensive written
specifications or standards that are consistent with the construction requirements of Part 195 as
required by § 195.202. Specifically, Enterprise failed to ensure that the Horizontal Directional
Drilling (HDD) operations were being performed by supervisors and construction personnel
thoroughly experienced with HDD installations and operations as required by the Enterprise
Products Engineering Standard, STD.8709, Horizontal Directional Drilling, Rev. 2.1, section 9.1.
During the inspection, the PHMSA inspectors requested documentation showing the qualifications
of the contractor representative in charge of the HDD or any of the contractor personnel performing
the work, but Enterprise failed to provide any supporting documentation.
4. § 195.214 Welding procedures.
(a) Welding must be performed by a qualified welder or welding
operator in accordance with welding procedures qualified under
section 5, section 12, Appendix A or Appendix B of API Std 1104
(incorporated by reference, see § 195.3), or Section IX of the ASME
Boiler and Pressure Vessel Code (ASME BPVC) (incorporated by
reference, see § 195.3). The quality of the test welds used to qualify the
welding procedures must be determined by destructive testing.
(b) Each welding procedure must be recorded in detail, including the
results of the qualifying tests. This record must be retained and
followed whenever the procedure is used.



Enterprise failed to perform welding according to a qualified welding procedure as required by
§195.214. During the PHMSA inspection, the welders did not have a copy of the qualified
welding procedure and were unable to identify the qualified welding procedure being used to
weld the new terminal piping located at the C-Rack at the Hobbs facility. The welders were also
unable to state any of the welding parameters from the qualified welding procedure that they are
required to follow when welding, such as voltage, amperage, and travel speed. Consequently,
the welding could not have been performed in accordance with a qualified welding procedure.
5. § 195.228 Welds and welding inspection: Standards of acceptability.
(a) Each weld and welding must be inspected to insure compliance with
the requirements of this subpart. Visual inspection must be
supplemented by nondestructive testing.
Enterprise failed to inspect each weld and welding to insure compliance with 49 C.F.R. Part 195,
Subpart D, as required by § 195.228. During the inspection, PHMSA questioned the welding
inspectors and welders about visual weld inspections of the completed welds. The welders
confirmed that neither the root bead nor first filler pass of the completed welds had been visually
inspected by the welding inspector. When PHMSA requested documentation for inspection of the
welds, the welding inspector could not provide any documentation of visual inspections and had
no records for checking the welding parameters of the qualified welding procedure, such as
voltage, amperage, travel speed, to ensure the welding was being performed according to the
qualified welding procedure. Consequently, each weld and welding were not inspected to insure
compliance with this subpart.
Under 49 U.S.C. § 60122 and 49 C.F.R. § 190.223, you are subject to a civil penalty not to exceed
$257,664 per violation per day the violation persists, up to a maximum of $2,576,627 for a related
