WARNING LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED
May 20, 2015
Ms. Colleen Starring
President
Enstar Natural Gas Company
P.O. Box 190288
Anchorage, AK 99519-0288
CPF 5-2015-0004W
Dear Ms. Starring:
On March 17-21, 2014, April 28-May 2, 2014, and June 2-6, 2014, a representative of the
Pipeline and Hazardous Materials Safety Administration (PHMSA), pursuant to Chapter 601
of 49 United States Code, inspected your natural gas distribution system in Anchorage,
Alaska.
As a result of the inspection, it appears that you have committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and
the probable violation(s) are:
1. §192.453 General.
The corrosion control procedures required by §192.605(b)(2), including those for
the design, installation, operation, and maintenance of cathodic protection
systems, must be carried out by, or under the direction of, a person qualified in
pipeline corrosion control methods.
Enstar Natural Gas Company (Enstar) did not document the qualified individuals who
performed periodic rectifier inspections and obtained readings. PHMSA representatives
discovered Corrosion Test Site Record forms, which were used to document rectifier
inspections and readings for Enstar’s cathodic protection system in the field that did not
indicate the individual qualified person who performed the task. Names and/or signatures
were missing from the forms on each date a particular rectifier location was inspected.



PHMSA representatives were unable to verify if a qualified individual performed the covered
task on each date of inspection. Enstar Operator Qualification Plan includes rectifier
inspection and readings as covered task number ASME-0101 “Inspect Rectifier and Obtain
Readings.”
2. §192.479 Atmospheric corrosion control – General
(a) Each operator must clean and coat each pipeline or portion of pipeline that is
exposed to the atmosphere, except pipelines under paragraph (c) of this section.
Enstar did not demonstrate that atmospheric corrosion repairs were completed as a result of
their periodic regulator station inspections. PHMSA representatives discovered Regulator
Station Maintenance Records for stations numbered A136 “Ft. Richardson Laundry” and
A140 “5th and Davis Hwy” that indicated “needs paint” on the date of inspection, April 24,
2013. At the time of inspection, no documentation was provided to demonstrate that the
“needs paint” indication was addressed and the date of completion.
3. §192.616 Public awareness.
(c) The operator must follow the general program recommendations, including
baseline and supplemental requirements of API RP 1162, unless the operator
provides justification in its program or procedural manual as to why compliance
with all or certain provisions of the recommended practice is not practicable and
not necessary for safety.
Enstar did not follow its procedures and did not adequately demonstrate that they are in
contact with all emergency officials annually. Enstar’s Standard Operating Procedures (SOP)
1162, titled “Public Awareness Program,” described a direct mailing process to send letters to
emergency officials every year by First Class US Mail. At the time of the inspection, PHMSA
representatives discovered only one letter that was mailed to emergency officials, dated
October 3, 2007.
Enstar did not adequately document audit results, findings, and/or improvements needed as a
result of its annual public awareness program audit for 2012 and 2013. Enstar did not
adequately document that it had addressed the action items indicated on audit records and
completed implementation of changes to the program.
Enstar did not follow API RP 1162 and did not complete effectiveness evaluations for all
stakeholder audience groups in their Public Awareness Program (PAP). PHMSA
representatives discovered that Enstar performed an effectiveness evaluation for only one
stakeholder audience group, the general public. Documentation was not provided for
effectiveness evaluations covering emergency officials, local public officials, and excavators.



Enstar did not document its effectiveness evaluation results, findings, and/or improvements
after completion of its 2009 and 2011 evaluations for the general public. Enstar did not
demonstrate that it reviewed the general public’s assessment results to determine PAP
effectiveness and implemented any changes if needed.
4. §192. 807 Recordkeeping.
Each operator shall maintain records that demonstrate compliance with this
subpart.
(b) Records supporting an individual’s current qualification shall be maintained
while the individual is performing the covered task. Records of prior
qualification and records of individuals no longer performing covered tasks shall
be retained for a period of five years.
PHMSA representatives discovered Operator Qualification (OQ) training records for two
Enstar supervisors that were not up-to-date with the expected qualification needs. These two
individuals were not re-qualified for covered task SOP 1150 titled “Damage Response
Procedures” within the required 3 year re-qualification period. Both individuals last took the
required written test for this covered task in 2009. Enstar must complete re-qualification for
these individuals or ensure that they do not perform any part of the covered task unless under
the direct supervision of a qualified individual.
5. §192. 1007 What are the required elements of an integrity management plan?
A written integrity management plan must contain procedures for developing
and implementing the following elements:
(b) Identify threats. The operator must consider the following categories of
threats to each gas distribution pipeline: corrosion, natural forces, excavation
damage, other outside force damage, material or welds, equipment failure,
incorrect operations, and other concerns that could threaten the integrity of its
pipeline. An operator must consider reasonably available information to identify
existing and potential threats. Sources of data may include, but are not limited to,
incident and leak history, corrosion control records, continuing surveillance
records, patrolling records, maintenance history, and excavation damage
experience.
Enstar did not adequately demonstrate that its Distribution Integrity Management Program
(DIMP) addressed risks specific to its higher pressure distribution main lines. PHMSA
representatives discovered higher pressure distribution main lines were included in the DIMP
in addition to its lower pressure distribution system.
Under 49 United States Code, § 60122, you are subject to a civil penalty not to exceed
$200,000 per violation per day the violation persists up to a maximum of $2,000,000 for a



related series of violations. For violations occurring prior to January 4, 2012, the maximum
penalty may not exceed $100,000 per violation per day, with a maximum penalty not to
exceed $1,000,000 for a related series of violations. We have reviewed the circumstances and
supporting documents involved in this case, and have decided not to conduct additional
enforcement action or penalty assessment proceedings at this time. We advise you to correct
the item(s) identified in this letter. Failure to do so will result in Enstar Natural Gas Company
being subject to additional enforcement action.
No reply to this letter is required. If you choose to reply, in your correspondence please refer
to CPF 5-2015-0004W. Be advised that all material you submit in response to this
enforcement action is subject to being made publicly available. If you believe that any
portion of your responsive material qualifies for confidential treatment under 5 U.S.C. 552(b),
along with the complete original document you must provide a second copy of the document
with the portions you believe qualify for confidential treatment redacted and an explanation of
why you believe the redacted information qualifies for confidential treatment under 5 U.S.C.
552(b).
