 Chris Wrobel, ConocoPhillips Alaska, Inc., states that the purpose is  to improve existing roads within the Kuparuk River Unit (KRU) by bringing them up to current engineering standards and providing safe travel for all types of equipment.

*Location: The project site is located within Section 24 T. 11 N., R. 8 E.; Sections 1, 11, 12, 14, 15, 16, 19, 20, 21, 29, & 32, T. 11 N., R. 9 E.; Sections 5, 6, 8, & 9, T. 11 N., R. 10 E.; Sections 2, 3, 10, 11, 15, 22, 23, 25, 26, & 36, T. 12 N., R. 9 E.; Sections 25 & 36, T. 13 N.,
R. 8 E.; Sections 28 & 33, T. 13 N., R. 9 E., Umiat Meridian; USGS Quad Map Beechey Point B-5; and Sections 23, 24, 26, & 27, T. 11 N., R. 8 E., Umiat Meridian; USGS Quad Map Harrison Bay B-1; with a centroid Latitude 70.3371º N., Longitude -149.7316º W.; half way between Prudhoe Bay and Nuiqsut, Alaska.

*Proposed Work: The placement of 293,000 cubic yards (cy) of gravel would be placed into 48 acres of Waters of the U.S., including wetlands (47.63 acres of Palustrine emergent (PEM) wetlands, 0.27 acre of Palustrine unconsolidated bottoms (PUB), and 0.1 Riverine
lower perennial unconsolidated (R2U)) for the widening of 26 miles of KRU roads and drill site access roads.  The roads would be 35 feet wide at the top of the road with the width varying at the toe-to-toe between 61 to 81 feet dependent upon the topography of the landscape.  The project would be phased over five years (starting in 2018 with the completion expected in 2022) with approximately six miles of road being completed each year.  The determining factor in which roads are completed first would depend on future drilling objectives. The complete project would place a total of 1,300,000 cy of gravel for road improvements, most of which would be placed on top of existing fill.  No new roads would be constructed under the proposed work.
