1-800-424-4372, ext. 0060
The U.S. Environmental Protection Agency (EPA) has direct implementation responsibility in Alaska for the regulation of Class I injection wells through the UIC program, which is authorized by Part C of the Safe Drinking Water Act. Class I injection wells are used for the deep disposal of industrial waste into naturally saline ground water, beneath any aquifers which could serve as current or future underground sources of drinking water (USDWs).
The facility and associated well was initially permitted with the EPA in November, 2004 under permit AK1I005-A. The current ten year EPA Class I Underground Injection Control (UIC) permit at Milne Point Facility will expire on November 2, 2014. BPXA has requested EPA to re-issue its Class I UIC permit that includes two Class I wells (or replacement wells if a well fails) including the existing well (MPB-50) that would continue to be utilized for the disposal of Resource Conservation Recovery Act (RCRA) Exploration and Production (E&P) exempt and non-exempt non-hazardous waste fluids including produced fluids in the oilfields that support the oil industry on the North Slope, Alaska.
EPA is proposing to re-issue BPXA’s Class I UIC permit, which will allow for the continuing operation of up to two Class I non-hazardous waste injection wells at Milne Point Facility. The existing active Class I well is located onshore at B-pad, Milne Point Facility, North Slope, Alaska.
EPA has considered available waste disposal options and determined that underground injection is an appropriate disposal method for RCRA E&P exempt and non-exempt non-hazardous waste fluids that includes oilfield produced water. Class I UIC well injection is an environmentally sound method for the RCRA E&P exempt and non-exempt waste fluid disposal that includes, but is not limited to treated sewage effluent, and this practice will eliminate or substantially reduce risk of discharge of oilfield production and domestic wastes to the surface waters of the North Slope. Class I wells increase safety and reduce environmental risks by reducing handling and transportation activities and provide safe subsurface disposal in a controlled manner. Re-issuance of BPXA’s Class I UIC Permit Number AK-1I005-B will allow EPA to maintain oversight and inspection of the wells. During the past nine years, EPA has inspected the facility on an annual basis during which mechanical integrity tests (MIT) were performed each year on the active well (MPB-50). The most recent MIT performed on the well and witnessed by EPA were in July, 2014.
The geologic setting at the Milne Point Unit (MPU) location is very compatible with the proposed deep disposal process. The naturally saline intervals of the Schrader Bluff (West Sak) and Ugnu (Prince Creek) Formations have been successfully used to dispose over 79.8 million barrels of waste fluids below the surface at MPU over the past approximately 9 years. The proposed EPA Class I permit limits injection to the existing and naturally saline injection intervals in the Schrader Bluff (West Sak) and Ugnu (Prince Creek) Formations that are located deeper than approximately 4200 feet below land surface. An aquifer exemption for Class I injection was granted by EPA on September 29, 2004. There are no underground sources of drinking water below the permafrost in the MPU area. The existing well (MPB-50) has successfully demonstrated mechanical integrity on an annual basis, and the MIT were witnessed by an EPA representative.
