Mr. David Harris
President & CEO
AltaGas, Ltd.

Calgary, Alberta Canada T2P 0J1

Dear Mr. Harris:
On April 5 and 6, 2017, representatives of the Pipeline and Hazardous Materials Safety
Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code (U.S.C.),
inspected your subsidiary, ENSTAR Natural Gas Company’s (ENSTAR’s) Cannery Loop
Gas Storage Field in Kenai, Alaska.
As a result of the inspection, it is alleged that you have committed a probable violation of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items
inspected and the probable violation is:
1. §192.475 Internal corrosion control: General.
(b) Whenever any pipe is removed from a pipeline for any reason, the internal
surface must be inspected for evidence of corrosion. If internal corrosion is
found—
(3) Steps must be taken to minimize the internal corrosion.



ENSTAR failed to document whether internal corrosion was present during the examination
of removed pipe. ENSTAR provided worksheets showing instances where the inside of the
pipe had been exposed, but the worksheets did not indicate whether evidence of corrosion was
observed.
As of April 27, 2017, under 49 U.S.C. § 60122 and 49 CFR § 190.223, you are subject to a
civil penalty not to exceed $209,002 per violation per day the violation persists up to a
maximum of $2,090,022 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 identified in this letter. Failure to do so will result in Alta Gas,
Ltd. 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 5-2017-0007W. 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).
Sincerely,
Dustin Hubbard
