WITHDRAWAL of NOTICE LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED

Dear Mr. Lance:
On September 13, 2017, Oliktok Pipeline Company, a wholly owned subsidiary of
ConocoPhillips, was issued a Notice of Probable Violation and Proposed Compliance Order
(NOPV/PCO) letter for the case number referenced above. The Notice alleged that Oliktok
Pipeline Company (OPC) violated 49 C.F.R. § 192.195 by failing to provide adequate
protection against overpressure on the Oliktok Gas Pipeline (OPL). The Notice proposed to
require OPC to make certain modifications to protect the OPL from unsafe operating
pressures. Specifically, the Notice alleged that a remotely operated valve, ROV 9000, is
located at the upstream end of the OPL. The valve was designed to “fail in place”, that is fail
in its last position. In the event of a power loss to the valve’s actuator, the valve “fails in
place” and becomes unable and incapable of responding to an overpressure situation.
ConocoPhillips responded to the NOPV/PCO in a letter dated October 11, 2017, offering
information concerning modifications it had made to ROV 9000 and requesting that the
NOPV/PCO be reduced to a warning. ConocoPhillips has provided PHMSA with
documentation that a failsafe design has been implemented. PHMSA is satisfied that
ConocoPhillips has addressed the probable violation alleged in the Notice. This letter



withdraws the NOPV/PCO. A follow-up Warning Letter will be issued addressing the issues
This letter is to inform you that PHMSA hereby withdraws the Notice and that the case is now
at hand.
closed.
Sincerely,
Kim West
Acting Director, Western Region
