Plan of Operations Amendment Decision Dear Ms. Heebner: The Alaska Department of Natural Resources, Division of Oil and Gas (Division), in accordance with Alaska Statute 38.05 and Alaska Oil and Gas Leasing Regulations (11 AAC 83) grants authorization to conduct activities on state lands as proposed in the Milne Point Unit (MPU). Plan of Operations (Plan) amendment application dated October 24, 2017 for the above referenced project. Scope: Hilcorp Alaska, LLC. (Hilcorp) proposes to add a total of 2.29 acres of additional gravel to L Pad in the MPU to install three turbine skids, associated infrastructure, and drill five additional development wells. The gravel will be added to L pad in three distinct sections, 0.2 acres (southeasterly side), 1.14 acres (southerly side), and 0.95 acres (northerly side). The purpose of this project is to increase the pad size to accommodate the turbine skids, diesel tanks, electrical equipment room, switchgear rooms and to accommodate the additional development wells. The MPU does not have any spare power for adding new production wells, so additional pad space is required for the facilities. The proposed activities are anticipated to occur between March 2018 and February 2019. Plan activities include: • Excavation of gravel from existing permitted sources • Placement of gravel on tundra by equipment working from existing gravel pad • Install vertical support members (VSMs) and pilings for turbine skids, fuel gas metering skid, fuel gas and diesel piping, electrical equipment rooms and switchgear room • Install fuel gas metering skid • Install diesel piping in existing F to L Pad water pipeline pipe rack adding up to three VSMs as required • Install fuel gas and diesel piping on VSMs on pad • Expand electrical skid at the entrance to L Pad, adding up to six VSMs • Install electrical equipment rooms and switchgear room
