Dear Mr. Knepper:
On August 28 through 31,2006 a representative of the Pipeline and Hazardous Materials
Safety Administration (PHMSA) pursuant to Chapter 601 of 49 United States Code inspected
CHS Inc.'s procedures for integrity management in Laurel, Montana.
On the basis of the inspection, PHMSA has identified the apparent inadequacies found within
CHS's plans or procedures, as described below:
1. 5195.452 Pipeline integrity management in high consequence arees.
$ rilhat are the elements of an integrity management program? An integrity
management program begrns with the initial framework An operator must
continually change the program to reflect operating experience, conclusions
drawn from results of the integrity assessments, and other maintenance and
surveillance data, and evaluation of consequences of a failure on the high
consequence area. An operator must include, at minimum, each of the following
elements in its written integrity management program:
(1) A process for identifying which pipeline segments could affect a high
consequence area;
(2) A baseline assessment plan meeting the requirements of paragraph (c)
of this section;
(3) An analysis that integrates all available information about the integrity



of the entire pipeline and the consequences of a failure (see paragraph (g
of this section);
(4) Criteria for remedial actions to address integrity issues raised by the
assessment methods and information analysis (see paragraph (h) of this
section);
(5) A continual process of assessment and evaluation to maintain a
pipeline's integrity (see paragraph (i) of this section);
(6) Identilication of prwentive and mitigative measures to protect the high
consequence area (see paragraph (i) ofthis section);
(8) A prlocess for review of integrity assessment results and information
analysis by a person qualilied to evaluate the results and information (see
paragraph (hX2) of this section).
o Item 1.A: $1es.4s2(D(r)
CHS's Integrity Management Program (IMP) does not contain enough detail regarding the
application of airborne toxicity buffers in determining which pipeline segments could affect
HCAs.
o ltem 1.8: Sl95 452(0(1)
CHS's IMP does not contain the process used by CHS to analyze the overland flow of liquids
released from potential pipeline failtres. This process must have sufficient detail to ensure
repeatability including the assumptions used for spill volume, the buffer size and the effects of
topography.
o Item l.C: 9r95.452(fxl)
CHS's IMP does not document the technical justification used for excluding tank volumes in
their detennination of facilifies and adjacent piping that may impact HCAs.
r Item l.D: gl95 452(fX2)
CHS's Baseline Assessment Plan has no provisions for assessing an each pipeline segment's
susceptibility to SCC. CHS stated thal they address SCC threats by performing magnetic
particle testing for all excavations involving repairs to dents and gouge type anomalies.
o Item l.E: 9195 452(fX3)
CHS's IMP does not contain a risk analysis that specifically addresses facilities and their
uique attributes.
r Item l.F: 5195 452(fX4)
CHS's IMP definition of "discovery" does not define a "discovery" process or provide
requirements regarding how much time can be taken to review information and declare



"discovery" following receipt of vendor reports or other information that includes evidence of
anomalies.
o ltem 1.G: 5195 452(D(4)
CHS's IMP does not speciS that "immediate" repair conditions must be repaired as soon .ui
possible.
o ltem l.If: Sl95 452(fX5)
CHS's IMP defaults to five years for all reassessments without any justification.
r ltem l.I: Sl95 452(D(5)
CHS's IMP does not contain a process for 1) examining causes of incidents, leaks, and near-
misses, 2) making recommendations for corrective actions, and 3) providing those lessons
learned to appropriate company employees.
o Item 1.J: 5195 452(fX6)
CHS's IMP does not describe a process for performing a leak detection evaluation as required
by $195.452(iX3). It is expected that such a leak detection process would include a
documented basis for all operator reactions credited in the leak detection evaluation.
o ltem l.K: 5195 452(fX6)
CHS's IMP does not describe a process for evaluating the need for additional EFRDs
including consideration of the factors required bV 195.a52(i)(a).
o ltem l.L: Sl95 452(D(8)
Appendix I of CHS's IMP specifies that anomalies selected for validafion are chosen from
anomalies in the "Marcimum, Minimum, and Midrange" (two from each). However, there was
no definition regarding what these ranges represent.
o Item 1.M: gl95 452(fX8)
CHS's IMP discusses how assessment results are integrated with pertinent pipeline risk-
condition information to discover integrity issues that might not be evident from the
assessment data done. However, the IMP does not provide details and specificity regarding
how this analysis is to be performed.
o Item l.N: gf95 452(fX8)
CHS's IMP does not contain a requirernent to document that an effective corrosion control



progmm is in place and that corrosion control is being effectively applied to segments where
hydro tests are performed as assessments.
