WARNING LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED

Mr. Todd Denton
President
Phillips 66 Pipeline, LLC
3010 Briarpark Drive
PWC-7109
Houston, TX, 77042
CPF 5-2014-5015W
Dear Mr. Denton:
From March 2013 through November 2013, representatives of the Pipeline and Hazardous
Materials Safety Administration (PHMSA) and the Washington Utilities and Transportation
Commission (WUTC), pursuant to Chapter 601 of 49 United States Code, inspected your
Yellowstone Pipeline System from Billings, Montana to Spokane, Washington.
As a result of the inspection, it appears that you have committed a probable violation of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected and the
probable violation is:



1. §195.452 Pipeline integrity management in high consequence areas.
(g) What is an information analysis? In periodically evaluating the integrity of each
pipeline segment (paragraph (j) of this section), an operator must analyze all
available information about the integrity of the entire pipeline and the consequences
of a failure. This information includes:
(4) Information about how a failure would affect the high consequence area, such as
location of the water intake.
At the time of the inspection, Hauser Lake was not defined as an HCA. However, interviews
with Phillips 66 personnel concerning the potential impacts to the reservoir and recreational
areas if a spill was to occur then the impact would be significant. Subsequently, Phillips has
indicated that they have designated the area as an HCA and have reevaluated HCAs along the
length of the pipeline.
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 Phillips 66 Pipeline, LLC being subject to additional enforcement
action.
No reply to this letter is required. If you choose to reply, in your correspondence please refer to
5-2014-5015W. 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).
