Installation of the 5MN Pipelines and access risers will involve placement of construction erosion <br />controls (silt fence and/or straw wattles), removal and windrowing of soil materials; excavation, <br />placement, and backfilling around the risers; trenching in most areas for pipeline placement; placement <br />of suitable bedding materials; placement, connection, and pressure testing of the pipelines; backfilling <br />and compaction of suitable fill materials around and over the pipeline; backfilling and compaction of <br />the trench; regrading; replacement of soil materials; and revegetation of all disturbed areas. It is not <br />anticipated that any of the planned activities will occur within stream buffer zones. <br />While the associated pipeline disturbance areas will essentially be reclaimed within a reasonable time <br />period following pipeline installation, TC does not consider these areas to be reclaimed for purposes of <br />reporting, since there is some potential that they may be re -disturbed for pipeline repair or maintenance <br />in the future. At the time of final reclamation, the access risers will be removed or demolished to 3 - <br />feet below grade, and the pipeline will be cut-off below grade, capped, and abandoned in place. At <br />that time, any necessary maintenance of regraded areas will occur, along with any necessary <br />supplemental seeding. <br />This submittal includes revised PAP text and supporting materials, as identified by the accompanying <br />Summary of Revisions/Additions. In order to complete the proposed pipeline installation activities <br />during the summer/fall field season, TC requests the assistance and cooperation of the CDRMS is <br />completing review and approval of this application in a timely manner. Once you have opportunity to <br />review this submittal, please feel free to contact me with any questions, or to discuss the submittal and <br />related matters. We appreciate your attention and assistance. <br />Best regards <br />i% <br />1 <br />ierry"Ne on <br />Manag r nvironmental Affairs <br />cc: Mike Berdine/TC <br />Ed Brady/TC <br />Cody Bartkoski/TC <br />
