CASEY Q. Y0"..1R101
The purpose of letter is to report our review of the horizontal and vertical alignment of
the Homer Deep Unit, Medium Pressure Gas Pipeline as prepared by Wier &
Associates, Inc. Survey Department. In addition, this Tetter reports our review of the
pipeline materials specified by Summit Midstream for the proposed gas pipeline
alignment. Based on our review, and for the stated Maximum Allowable Operating
Pressure (MAOP) of the pipeline as provided by Summit Midstream, the specified
materials and layout of this pipeline appear to meet current design standards of AMSE
B31.8, Title 49 -- Pipeline Safety Party 192 Transportation of Natural and Other Gas by
Pipeline and generally accepted engineering practices.
This review does not waive the need for quality control during the construction phase. It
is highly recommended that testing of backfill compaction be performed at specified
stations and lifts per ASTM guidelines, and at critical areas along the pipeline. In
addition, an accurate survey of the pipeline placement should be documented and
Record Drawings should be prepared for future reference and location of the pipeline.
Finally, the proper pressure testing of the pipeline, based on pipeline class and the
current ASME B31.8 testing standards shall be performed with results properly
documented before the pipeline is placed into service.
Sincerely,
