WARNING LETTER
CERTIFIED MAIL - RETURN RECEIPT REQUESTED
August 19, 2013
Mr. Vern Meier
Vice President, Field Operations
TransCanada, Great Lakes Gas Transmission
717 Texas Avenue, Suite 2400
Houston, Texas 77002-2761
CPF 3-2013-1014W
Dear Mr. Meier:
On May 14 – May 18, July 30 – August 2, September 17 - 25, October 4 and November 2,
2012, representatives of the Michigan Public Service Commission (MI-PSC) and the
Minnesota Office of Pipeline Safety (MNOPS) acting as interstate agents the Pipeline and
Hazardous Materials Safety Administration (PHMSA) pursuant to Chapter 601 of 49
United States Code inspected your pipeline facilities in Minnesota and Michigan.
As a result of the inspection, it appears that you have committed probable violations of the
Pipeline Safety Regulations, Title 49, Code of Federal Regulations. The items inspected
and the probable violation(s) are:
1. §192.605 Procedural manual for operations, maintenance, and emergencies
Each operator shall maintain the following records for transmission line for the
periods specified:
(a) General. Each operator shall prepare and follow for each pipeline, a manual
of written procedures for conducting operations and maintenance activities and
for emergency response. For transmission lines, the manual must also include
procedures for handling abnormal operations. This manual must be reviewed
and updated by the operator at intervals not exceeding 15 months, but at least
one each calendar year. This manual must be prepared before operations of a
pipeline system commence. Appropriate parts of the manual must be kept at
locations where operations and maintenance activities are conducted.



Great Lakes personnel did not follow their procedures for the inspection of the over-
pressure protection devices. TransCanada ANR’s procedures “DOT Regulator
Inspection and Maintenance, Section 5.0” and “Pressure Safety Valve Inspection
Section 5.0” both require that the “As Found” and “As Left” data be recorded. This
was not being documented on the overpressure protection inspection forms for Thief
River Falls and the Shevline Compressor Stations in Minnesota and Crystal Falls
Station in Michigan.
Great Lakes personnel indicated that the relief devices at the stations were inspected,
but could not provide documentation for the “As Left” and “As Found” data on the
overpressure protection forms.
2. §192.707 Line markers for mains and transmission lines.
(d) Marker warning. The following must be written legibly on a background of
sharply contrasting color on each line marker:
(1) The word "Warning," "Caution," or "Danger" followed by the words
"Gas (or name of gas transported) Pipeline" all of which, except for
markers in heavily developed urban areas, must be in letters at least 1
inch (25 millimeters) high with ¼ inch (6.4 millimeters) stroke.
Great Lake’s line markers did not contain marker warnings legibly on a background of
sharply contrasting color on numerous line markers throughout their system in
Minnesota and Michigan.
During the Minnesota field inspection, the marker warning on line markers were noted
as being faded/unreadable. There were a significant amount of line markers with faded
lettering that could not be read. The areas of pipeline right-of-way seen during the
inspection with faded line markers included Bemidji to Grand Rapids, Minnesota.
Pictures of a the line markers at Mile Post 149.5, Mile Post 250, and Grand rapids
Station were taken as a representative sample of the condition of the line markers.
Additionally, in Michigan, it was noted that line markers were faded throughout the
system. During the Blue Lake Area field inspection, the marker warning on the line
markers were observed as faded and unreadable at Mile Post 734.7 and 726.0. It was
also noted in the Northern Lakes Area field inspection where the marker warning on
numerous line markers were observed as faded and unreadable.
After the inspections, Great Lakes personnel surveyed and replaced all the faded line
markers along their right-of-way.
