Dear Mr. Mattson:
On July 27-29, 2010, a representative from the Pipeline and Hazardous Materials Safety
Administration (PHMSA), pursuant to chapter 601 of 49 United States Code, conducted an on-
site pipeline safety inspection of BP Exploration Alaska's procedures for the Badami Natural Gas
Transmission Pipeline in Prudhoe Bay, Alaska.
As a result of the inspection, BP Exploration Alaska was issued a Notice of Amendment on
September 21, 2010, which proposed amendment of your procedures.
BP Exploration Alaska submitted its amended procedures on October 20, 2010. My staff
reviewed the amended procedures, and it appears that the inadequacies outlined in this Notice of
Amendment have been corrected.
This letter is to inform you no further action is necessary and this case is now closed. Thank you
for your cooperation.
Sincerely,

NOTICE OF AMENDMENT
CERTIFIED MAIL - RETURN RECEIPT REQUESTED [7007 2560 0000 7825 9471]

Dear Mr. Mattson:
On July 27-29, 2010, a representative of the Pipeline and Hazardous Materials Safety
Administration (PHMSA), pursuant to Chapter 601 of 49 United States Code, inspected BP
Exploration Alaska’s (BPXA) procedures for the Badami Natural Gas Transmission Pipeline
in Prudhoe Bay, Alaska.
On the basis of the inspection, PHMSA has identified the apparent inadequacy found within
BPXA plans or procedures, as described below:
1. §192.605 Procedural manual for operations, maintenance, and emergencies
(b) (3) Making construction records, maps, and operating history available to
appropriate operating personnel. (3) Making construction records, maps, and
operating history available to appropriate operating personnel.
A. The Pipeline Alignment Sheet (G 254) indicated that the pipe wall thickness was .432
inches for the entire pipeline. The Badami Pipeline Site Specific DOT Operations,
Maintenance, Emergency Response (OMER) Manual lists the belowground river
crossings (Kadleroshilih, Shaviovik, and Sagavanirkok river crossings) as .432 wall
thickness and the rest of the pipeline as .375 wall thickness. During the field
inspection, pipe was found marked .432 wall thickness at the cased crossing at
Badami, and .375 along the causeway. The alignment sheets need to indicate the
actual wall thickness of the pipeline.
B. The Operator’s Badami Natural Gas pipelines, DOT Operation, Maintenance,
Emergency Response Manual (OMER) was found in need of updating as follows:



1. Page 5, “Physical Description” indicate that the Technical Specifications are
found in Appendix F ( they are found in Appendix A), DOT equipment are found
in appendix G (they are found in appendix B) and DOT boundaries are in
appendix H ( they are in appendix C)
2. Page 27, Appendix A, Technical Specifications indicate that the valves are rated
ANSI 600 #. This not consistent with the MAOP or the flange rating.
