Mr. John Zager
General Manager
Union Oil Company of Cahfornia

Anchorage, AK 99501
CPF 5-2008-7001W
Dear Mr. Zager:
Between September 1 land 14, 2007, representatives of the Pipeline and Hazardous Materials
Safety Admmistration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected
your procedures and records for Union Oil Company of Cahfornia's (UNOCAL) Integrity
Management Program in Anchorage, Alaska.
As a result of the inspection, it appears that you have committed probable violations of the
Pipehne Safety Regulations, Title 49, Code of Federal Regulations The item inspected and
the probable violation is
$195. 452 (i) What preventive and mitigative measures must an operator take to
protect the high consequence area? (3) Leak detection. An operator must have a
means to detect leaks on its pipeline system. An operator must evaluate the
capability of its leak detection means and modify, as necessary, to protect the high
consequence area. An operator's evaluation must, at least, consider the following
factors-length and size of the pipeline, type of product carried, the pipeline's
proximity to high consequence area, the swiftness of leak detection, location of
nearest response personnel, leak history, and risk assessment results.



UNOCAL has not conducted an adequate analysis of its leak detection systems to
evaluate the capability of its leak detection system, as necessary, to protect the high
consequence area. UNOCAL's leak detection evaluation must, at least, consider the
following factors: length and size of the pipeline, type of product carried, the pipehne's
proximity to high consequence area, the swiftness of leak detection, location of nearest
response personnel, leak history, and risk assessment results. UNOCAL initiated a
review of its leak detection capabihties m 2002, but did not adopt the recommendations
of the draft proposal from the Vendor, due to the multi-phase flow of the pipehne.
UNOCAL chose not to adopt the Vendor's proposal at that time and as a result,
UNOCAL has not formally completed the leak detection study.
Under 49 United States Code, ) 60122, you are subject to a civil penalty not to exceed
$100, 000 for each violation for each day the violation persists up to a maximum of $1, 000, 000
for any related series of violations. We have reviewed the circumstances and supporting
documents mvolved 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 items
identified in this letter. Failure to do so will result in UNOCAL bemg subject to additional
enforcement action.
