RE: Major Grading Permit Application: Mesa Pipeline, LINN Operating: GRAD -3306
Dear Andy:
This office has performed a review of the documents provided for the Major Grading Permit
Review Application of the Mesa Pipeline for LINN Operating, Inc. The submittal was found to
be thorough and well organized. The following comments were generated:
1. The Applicant should explain the parameters to be used for the rockfall hazard assessment,
explain what the anticipated protection measures are, and how the measures might be
implemented and/or installed.
2. The Applicant should explain how the pipe and coating is to be protected for the above-
ground construction.
3. The Applicant should identify what will be used to pressure test the pipeline and also the
associated filling, emptying, and disposal,
Feel free to call if you have any questions or comments.
Sincerely,
Mounta'n Cross Enginee ng, Ijc.

I will make it a condition to the permit. "As a condition to the permit and prior to construction, please provide specific
details involving the means and methods of construction, specifications and installation related to the above ground
pipeline section. This report should be sealed by an engineer."
Sounds like a good idea to me.
Thanks,
Andy

Andy:
I have reviewed the additional materials and contacted Mr. Don Berger to discuss his response to my comments. In
general the plans and specifications are very specific to the below grade construction. However the above grade
construction is vague with the main provision for construction being that the pipe has an increased wall thickness to
help protect the pipe from damage due to construction and rockfall. In conversation with Mr. Berger, there are not
available specifications for the above ground construction of pipe. The means and methods of construction and pipe
protection are likely going to be specific to the contractor selected, however LINN hasn't selected a contractor yet.

I think that it's prudent to have some understanding of the means and methods for the above ground construction
and/or construction specifications prior to beginning so that there are some assurances for safety and the integrity of
the pipe. I am wondering if we could have the selected contractor submit these prior to beginning construction?
Let me know your thoughts. Thanks in advance.

Phil,
Please see attached letter from Chris Hale. I believe a narrative with the added details for the 3 items and the bond are
all that is needed to get the permit issued.
Thanks,
Andy
