NOTICE OF ANALYSIS AND PROPOSED DECISION
TRANS-ALASKA PIPELINE SYSTEM, ADL 63574
Sagavanirktok River EROSION CONTROL STRUCTURE
The Alaska Department of Natural Resources (DNR), pursuant to Alaska Statute (AS) 38.35.080, hereby gives notice that DNR has prepared an Analysis and Proposed Decision for a request submitted by Alyeska Pipeline Service Company (APSC), to amend the Trans-Alaska Pipeline System (TAPS) Right-of-Way (ROW) Lease, ADL 63574. DNR proposes to add lands to the TAPS ROW approximately 48 miles south of Pump Station 1 in Deadhorse, Alaska. Recent high erosion events along the Sagavanirktok (Sag) River have resulted in channel changes and increased bank erosion towards TAPS. If not mitigated, erosion is likely to continue and could threaten TAPS in a major flood event.
APSC proposes to build a buried sill approximately 600 feet long using Class III and IV riprap between existing Spur Dikes 3 and 4 on the existing land buffer between TAPS and the Sag River. The proposed construction ROW is near TAPS Pipeline Milepost 48 and approximately 885 ft. long by 348 ft. wide. The project is located within SW1/4SE1/4 Section 23, Township 3 North, Range 14 East, Umiat Meridian; and containing approximately 7.06 acres.
The public is invited to comment on the Analysis and Proposed Decision. Comments must be submitted in writing to the address below before 5:00 p.m. on July 20, 2020. If public comment indicates the need for significant changes in the proposed decision, then additional public notice will be given on or after July 20, 2020. If no significant changes are required, then the proposed decision, including any minor changes, will be issued without further notice as the final decision after July 20, 2020.
The public may obtain printed copies of these documents, at cost, from the address below. The documents are also available online at: http://dog.dnr.alaska.gov/Home/Newsroom .
