Petroleum News

Oil Search (Alaska) has filed an application with the U.S. Army Corps of Engineers Alaska District to discharge fill into wetlands for support facilities for the company’s proposed seawater treatment plant, part of the company’s proposed Pikka development. The work described in the application is at several sites some 32 miles west of Deadhorse, Alaska, the Corps said.

The application covers the following discharges:

*7,900 cubic yards of fill into 1.2 acres of wetlands for equipment crossings for the sea water treatment plant, STP.

*8,800 cubic yards of fill into 0.4 acre of wetlands for STP road pipeline crossings.

*1,600 cubic yards of fill into 0.2 acre of wetlands for STP pigging platform at Spine Road Y.

*3,000 cubic yards of fill into 0.5 acre of wetlands for gas spur pipeline equipment crossings.

*4,400 cubic yards of fill into 0.4 acre of wetlands for gas spur pipeline parking pad/platforms at DS-1C Road.

*1,500 cubic yards of fill into 0.2 acre of wetlands for 30 STP vertical support members.

*1,840 cubic yards of fill into 0.1 acre of wetlands for 460 gas spur pipeline VSMs.

*170 cubic yards of fill into 0.1 acre of wetlands for bonding cable trenching.

The Corps said the total proposed discharge is 29,210 cubic yards into 3.1 acres of wetlands.

Purpose of the seawater treatment plant “is to provide a long-term supply of fuel gas and sea water that is reliable and in sufficient quantity to allow Oil Search (Alaska) to optimize production efficiency from the Pikka Development project,” the Corps said.

This would be a modification of the original permit, POA-2015-00025, issued under the Nanushuk project environmental impact statement.

The Corps issued a public notice of the application Jan. 31; comments are due March 2.
